Installation Guide
About NetMaster NetMaster is a comprehensive Network Management System offering centralized operation and maintenance capability for a range of network elements. NetMaster offers full range management of network elements. It has the ability to perform configuration, fault, performance and security management. NetMaster is the user interface to transmission and access products and the key issue for the system is to present management networks in the simplest possible manner. The software has network auto-discovery and uses the configuration data in the network elements to automatically build the managed network. The various elements and their attributes may be accessed using the intuitively graphical presentation of the element and its components. NetMaster has a continuously updated display of network status and network events are reported from the elements using notifications. An extensive database and context sensitive help facilities enable the user to analyze and report network events. NetMaster provides the following network management functionality: Fault Management Configuration Management Performance Monitoring Security Management Graphical User Interface with Internationalization Network Topology using Perspectives and Domains Automatic Network Element Discovery
HW and SW Inventory Software Download jobs Northbound interface to higher order OSS Report Generator
Functionality is maintained during network growth, with solutions covering the entire range of radio networks from a single hop to nationwide multi-technology networks. High availability and reliability is obtained through various redundancy schemes. NetMaster functionality
The NetMaster system is scalable both in size and functionality. The NetMaster NMS Server is the basis for any NetMaster system, providing basic functionality within the Fault, Configuration, Performance and Security (FCPS) management areas. The NMS Server is by itself an advanced tool for the user to perform operations and monitor network elements for the whole operational network in real time. The flexible client/server architecture gives the operators easy access to all network elements and full control of the system from many different locations. By selecting among a set of optional features, the NetMaster system can be enhanced and tailored to each operator’s individual needs and requirements. With Ceragon Proprietary and Confidential

Installation Guide
NetMaster Installation The language of the operating system and database on which NetMaster is installed must be English (U.S.).
2.1
NetMaster Installation on Windows
2.1.1
Language and Date/Time format requirements When installing NetMaster on a Windows machine, make sure the Windows language format and date and time formats are as shown in the figure below.
2.1.2
Special Requirements for Windows 2012 Server To improve overall system performance in large-scale setups using a Windows 2012 server, it is recommended to set the server’s power plan (in Control Panel > All Control Panel Items > Power Options) to High Performance. Note that if you are installing NetMaster on a Windows 2012 server with multiple Ethernet NICs, you must set the priority of each NIC such that one NIC is the primary or prioritized NIC and the others are standby. If this is not done, the NetMaster license generated for the machine may be generated for the wrong MAC address, with the result that the NetMaster server will not run.

Installation Guide
NetMaster Server Pre-Installation for Windows Prepare Database
NetMaster Server requires a database to work. Make sure that a database server is installed and reachable from the computer on which you want to install NetMaster Server. The database server can be installed on the same computer as the NetMaster Server – refer to the NetMaster System Requirements document for guidance. However, it does not need to be installed on the same computer. If the database server is running on a different computer than the NetMaster Server, the firewall settings on the database server may have to be modified (i.e. open the port used for communication with the database server). Oracle and PostgreSQL database servers are supported – see the NetMaster System Requirements document for information about supported database editions. Note that these pre-installation steps are not required for NetMaster Client or the Northbound SNMP Agent installations. Java installation 1. We recommend removing all JRE installations from the computer on which
you will install NetMaster (client and/or server) 2. Download both the 32 and 64 JRE versions from the official Oracle site:
JRE and JDK 1.7.80 can be found currently on the following Oracle links: http://www.oracle.com/technetwork/java/javase/downloads/jre7downloads-1880261.html http://www.oracle.com/technetwork/java/javase/downloads/javaarchive-downloads-javase7-521261.html#jdk-7u80-oth-JPR Note: The Oracle links for downloading JRE and JDK 1.7.0_80 may change. Take care to download the recommended JRE version which is 1.7.0_80, except in the case of Windows 2012 where you should download version 1.7.0_45. 3. Install both the 32 and 64 JRE versions. 4. Configure two system environment variables to point to the two JRE versions.
For example: Variable name: NMS_JAVA_HOME_32 Variable value: C:\Program Files (x86)\Java\jre7 Variable name: NMS_JAVA_HOME_64 Variable value: C:\Program Files\Java\jre7 5. Restart the computer.

Note:
Installation Guide
All NetMaster services must be stopped before installing the new version. This includes the NetMaster Server, the NetMaster System Manager, and the NetMaster SNMP Agent. In rare cases in which you do not manage to stop one of these services, you must reboot the machine and then verify these services are stopped.
If the installer detects an older version of NetMaster installed on the computer, the installer will run in Upgrade mode. In this mode you will be able to upgrade the existing components and also to reselect which components to be installed on the computer. The existing installation will be uninstalled and replaced with the components selected in this maintenance installation. Note that existing components not selected will be uninstalled. NetMaster System Manager can be launched after the NetMaster software installation and gives options to upgrade or reset the NetMaster database. Note:
Action permissions for new functionality are default disabled for all user groups; these must be specifically granted for user groups needing access. The netmaster_environment.cmd file will be generated however the database administration user and password will be left empty.
Most of the installation steps are identical to the New Installation mode: Introduction step – informs that a previous version of NetMaster is detected, and displays some information about the detected installation.
License Agreement step is omitted in upgrade installations. Choose Install Items step – this step initially displays the components detected in the existing NetMaster installation. In this step you can select which components to be installed on the computer. Note that if you deselect existing components, those will be uninstalled. Choose Install Folder and Choose Shortcut Folder steps – omitted in upgrade installations. The installer will use the folders detected from the previous installation. Pre Install Summary step – gives an overview of the current selections. Installing step – watch the product features being presented during the installation progress. Installation Summary – same as in new installations.
Proceed with the NetMaster Server Post installation steps. As a final step, delete the following two folders:
C:\Program Files (x86)\NetMaster\Server\JBoss-4.2.3\server\ngnms\tmp C:\Program Files (x86)\NetMaster\Server\JBoss-4.2.3\server\ngnms\work

Installation Guide
Server High Availability considerations
Both NetMaster servers participating in a server high availability setup must run the same software version. Therefore, to upgrade the NetMaster versions of two NetMaster servers in a High Availability configuration, you must perform the following: 1. Uninstall NetMaster from both servers. 2. Install the new NetMaster version on both servers. 3. On both server, open System Manager and run the Initial Setup wizard,
specifying the existing database. This will automatically upgrade the existing database.
4. Reconfigure Server High Availability in System Manager. 5. Start the primary server. 6. Start the secondary server.
2.1.4.4
Maintenance installation If the installer detects an existing NetMaster installation with the same version, the installer will run in Maintenance mode. In this mode you will be able to reselect which components to be installed on the computer. The existing installation will be uninstalled and replaced with the components selected in this maintenance installation. Existing components not selected will be uninstalled. NetMaster System Manager can be launched after the NetMaster software installation and gives the option to reinitialize the NetMaster database. Most of the installation steps are identical to the New Installation mode:
Introduction step – informs that an existing installation is detected, and displays some information about the detected installation. Choose Install Items step – this step initially displays the components detected in the existing NetMaster installation. In this step you can select which components to be installed on the computer. Note that if you deselect existing components, those will be uninstalled. Installation Summary - same as in new installations. Installing step – the existing NetMaster installation will be uninstalled before this installer installs the selected components. (This step requires no user interaction)
Pre Install Summary step – this step gives an overview of the current selections.

Installation Guide
System Manager Installation on Database Server The System Manager tool is installed together with the NetMaster Server and provides the NetMaster operators an easier and more flexible way to deal with some NetMaster administrative tasks: Set up NetMaster database connection
Upgrade old NetMaster database to a new version Backup/restore database (requires System Manager on database server)
Schedule database backup and database maintenance tasks Configure email notification
Start and stop of NetMaster Server
As database backup and restore operations MUST be run on the actual database server, you have to install System Manager as a standalone application on your database server if you want System Manager to handle database backup and restore for you.
A database export will then work like this: 1. User logs on to System Manager on the NetMaster server and requests a
database backup. (Or a periodic database backup job has just started.) 2. A request is sent to System Manager on the database server that runs a
database backup job and stores the export file in the default folder C:\NgNMS\backup\database on the database server. 3. System Manager on the NetMaster server then copies the newly created
database export file from the database server and places it in the location specified in the Database view available from the System Manager Settings menu. The default location is C:\NgNMS\backup\database on the NetMaster server.
Ceragon Proprietary and Confidential

NetMaster NMS R15A01
Notes:
Installation Guide
If System Manager is not installed on the database server, the database backup and restore feature in System Manager is not available. If the local computer has more than one network card, in order to let know to System Manager which IP can be used for remote connection with secondary System Manager please define own IP in C:\Program Files (x86)\NetMaster\SystemManager\sysman.properties In the case of a backup done before an upgrade operation (started either from the Initial Setup Wizard or from the "Upgrade User/Schema" menu), the backup is kept only on the database server.
2.1.5.1

Page 27 of 68
NetMaster NMS R15A01
Installation Guide
All configuration should in general take place using the System Manager that is installed on the NetMaster server, and not on the Database Server. However, please note that database backups will by default be saved in a folder on the same drive as the database installation folder. As the database backups occupy too large amounts of space on the storage drive, it might be helpful to change the database folder to a location on a different drive. On a system with standalone Database Server, this must be done manually. How to change folder for backups on a standalone Database Server
If you want to change the folder for backups on a standalone Database Server, do the following: 1. On the database server, go to the folder:
/SystemManager/conf/system/
2. Open the file:
[email protected] 3. Change the path to another existing location and save the file

NetMaster Installation on Solaris
2.2.1
NetMaster Server Pre-installation for Solaris Register NetMaster Server at DNS
To establish connection between NetMaster Client and NetMaster Server, it is required that the NetMaster Server host is registered in DNS. Prepare Database
NetMaster Server requires a database to work. Make sure that a database server is installed and reachable from the computer on which you want to install NetMaster Server.
Ceragon Proprietary and Confidential
Page 30 of 68
NetMaster NMS R15A01
Installation Guide
If the database server is running on a different computer than the NetMaster Server, the firewall settings on the database server may have to be modified (i.e. open the port used for communication with the database server). Supported databases are Oracle and PostgreSQL. See the NetMaster System Requirements document for information about supported database editions. Note:
For an Oracle database ,we recommend installing a stand-alone database on Windows Server 2008 64bit platform instead, using the procedure System Manager Installation on Database Server.
Java installation
The Java Runtime environment (JRE) can be downloaded from the Internet. Note:
Solaris 11 comes with a pre-installed JRE, so if you are installing NetMaster on Solaris 11, check whether JRE version 1.7.0_xx, where xx is 45 or higher, is installed. If yes, no further steps are necessary. If however JRE is not installed, or a version lower than 1.7.0_45 is installed, or a version 1.8.0.xx or higher is installed, then follow the instructions in this sections.
JRE and JDK 1.7.80 can be found currently on the following Oracle links: http://www.oracle.com/technetwork/java/javase/downloads/jre7-downloads1880261.html http://www.oracle.com/technetwork/java/javase/downloads/java-archivedownloads-javase7-521261.html#jdk-7u80-oth-JPR Note: The Oracle links for downloading JRE and JDK 1.7.0_80 may change. Take care to download the recommended JRE version which is 1.7.0_80, After the JRE 1.7.0_80 is installed, do the following steps: 1. Open a command prompt (cmd). 2. Verify that the installed JRE is in PATH by typing java –version 3. If the java command is not recognized, you must add the bin directory under
the JRE installation directory to the PATH 4. If the command is recognized, you shall see the version of the installed JRE
which shall be 1.7.0_80. If the version is not 1.7, do the following (assuming you have version 1.7.0_80): cd /usr rm java ln -s /usr/jre/jre1.7.0_80 java Prepare Apache Ant
Ensure that Apache Ant of version at least 1.8.1 is installed on the Solaris machine. If not installed, do the following: 1. Install ant (unpack the archive from folder /ant on installation media) on a file
system with enough space.
Ceragon Proprietary and Confidential

2. Create a symbolic link:
ln -s /apache-ant-1.8.1/bin/ant /usr/bin/ant
Server High Availability considerations
Both NetMaster servers participating in a server high availability setup must run the same version of Solaris. You must verify this yourself, as this is not checked by the application. Full server high availability functionality is provided whether both NetMaster servers run Solaris 10 or Solaris 11.
2.2.2
NetMaster Server Installation for Solaris The following chapter guides you through NetMaster Server, System Manager and SNMP Agent installation on Solaris platform. This guide requires that the steps for Pre Installation for Solaris already have been completed.

Installation Guide
Install Modes
For the Solaris platform, this version of the installer supports only new installations. (No Upgrade/Maintenance). This means that you must uninstall the current version before installation. Please note that the installation of NetMaster on Solaris is less automated compared to Windows installer, and some steps need to be done manually. 2.2.2.2
New Installation Note:
For the Solaris platform, this version of the installer supports only new installations, no Upgrade or Maintenance. This means that you must uninstall the current version before installing a new version.
Execute the installer as root Unpack the NetMaster installer netmaster-sol_R****.zip to a temporary folder and do the following: cd /Disk1/InstData/NoVM/ sh Setup.bin When choosing installation directory in the installer, ensure that the folder has enough free space, and is within the boot partition. This is to make sure that the services will start automatically after a reboot of the machine. Complete the installation wizard. The steps in the installation for Solaris are basically the same as in New Installation for Windows, except that Client is not an option in Solaris version. If the Installer reports that the installation succeeded with some errors, you can search for ERROR in /NetMaster_InstallLog.log. If the only errors relates to Modify Text File and Create Link, then everything is OK. 2.2.2.3
Register NetMaster Services When installation wizard is completed, register services by executing: cd ant Check Service Status
If you want to check the status of the NetMaster services: svcs ngSysMgr ngNMSService ngNIFService If you installed NetMaster Server (ngNMSService), System Manager (ngSysMgr) and SNMP Agent (ngNIFService), the result should be something like this: STATE

Post Installation
2.3.1
NetMaster Server post installation This section describes post installation steps for a NetMaster Server installation. This guide requires that the steps for NetMaster Installation on Windows or NetMaster Installation on Solaris already have been completed. Note that for a new and upgrade installation, NetMaster is not ready to run until System Manager's NetMaster Initial Setup wizard is completed. Windows only: Windows Services and Server Monitor
At the end of an installation on Windows platform, the NetMaster Server is installed as a Windows service and a Server Monitor application is automatically started (look for the systray icon ). If you don't want the NetMaster Server to start automatically upon computer reboot, you can set the mode of the NetMaster Service to manual in the Services applet in the Control Panel.

Installation Guide
System Manager The System Manager tool contains database related tasks and also general NetMaster maintenance tasks intended to ease NetMaster configuration. After closing the NetMaster Installer you will be prompted to start the System Manager to complete the NetMaster configuration (this is only valid for Windows platform for Solaris platform, System Manager must be launched manually) Log in using System Manager administrator user. System Manager will if needed automatically launch the NetMaster Initial Setup wizard that will help you through the necessary setup pages. The initial authentication credentials for the System Manager administrator are: User name: root Password: pw Note:
It is strongly recommended to change the password of the root account as soon as possible to prevent unauthorized access. To change the password, open the System Manager Settings view.
See System Manager online help or PDF document on install media for more information. 2.3.1.4
NetMaster Heap Size configuration NetMaster is predefined with a Maximum Heap Size of 768 MB. However this parameter should be tuned on servers where the number of managed network elements is expected to increase above 100. The maximum allowed heap size is highly dependent on available memory on the server. To configure the heap size: 1. In the NetMaster System Manager: open the Settings menu and click
NetMaster Server.
2. Change the default value for Maximum Heap Size to a new value. i.e. 1400. 3. Restart NetMaster Server
If the server fails to start, reset the Maximum Heap Size, as above, using a lower value than the one suggested. If the server starts successfully, leave the server running or increase the value even further until server start fails. Then use the last value it successfully started with. Server should now have an optimal Heap Size. 2.3.1.5
Firewall settings If connecting any remote NetMaster clients to the server, and the computer’s firewall is enabled, it is necessary to configure the firewall to allow the following ports to be opened towards the NetMaster application server:

NetMaster Server High Availability Server High Availability is intended to ensure continuous NetMaster operation. NetMaster also offers a Database High Availability option, which can be implemented if Server High Availability is implemented. For information about database high availability, refer to NetMaster Database High Availability.
3.1
Overview In a server High Availability setup, two NetMaster servers (called mates) are configured so that one is the Primary server, and the other is the Secondary server. At any given time only one of the two servers is Active and the other is on Standby. The Active server can both read from and write to the database, while the Standby can only read from the database. NetMaster clients are always connected to the Active server. The Primary server is the Active server unless it has stopped. If the Primary server is stopped, the Secondary server becomes the Active server and the Primary server becomes the Standby server. When the Primary server is restarted, it switches back to being the Active server (after a pre-configured grace period), and the Secondary server switches back to being the Standby server.
3.2
Database architecture supporting NetMaster server High Availability The NetMaster Server High Availability solution supports the following database architectures: A single Relational Database Management System (RDBMS) and single database – Postgres or Oracle. Multiple RDBMS and single database – using Oracle RAC.
3.3
NetMaster server High Availability configuration instructions Setting up a server High Availability solution requires the following: 1. Defining certain settings during the initial setup stage of the Primary server
and Secondary server. Refer to Initial setup of NetMaster servers participating in server High Availability.
2. Configuring the two NetMaster servers for High Availability. Refer to:
a. Prerequisites to configuring Server High Availability b. Configuring Server High Availability c. Setting up secure communications between the two mate machines

Prerequisites to configuring Server High Availability
You must obtain a license with a server High Availability feature for each of the two servers. The license settings on both servers must be identical. The Operating System on both servers must be identical: either both Solaris or both Windows. The NetMaster version on both servers must be identical. Both servers must use the same user/schema. Both servers should be set up as Trap Managers. Northbound interface should be configured for both servers. In both servers, the NG NMS SNMP Agent service should be set (in the operating system’s Services) to start automatically upon a server restart. Ensure that the UTC time on both servers is the same. System Manager must be installed on all servers in which a NetMaster server and/or database are installed.

Installation Guide
Configuring Server High Availability 1. Run System Manager for both servers. 2. Stop both servers by pressing Stop in the Dashboard View of their System
Managers.
3. Ensure there is connectivity between the two System Managers. 4. For each of the two servers, load a license in which High Availability is
enabled, and run one of the following: Import License Wizard to import a new license into NetMaster. Update Capabilities wizard to invoke the additional capabilities provided by a new imported license.
5. Configure secure communications between the machine hosting the Primary
server and the machine hosting the Secondary server, as described in Setting up secure communications between the two mate machines. This will enable file synchronization for server High Availability.
6. In the NMS HA View of the Primary server’s System Manager:
a. Set the Server Mode to Primary. b. Optionally change the default settings of the Automatic Switch Time and Time for sync file system fields. c. Specify the IP address of the Secondary server in the Mate Server IP field. d. Specify a domain username of the mate server in the Mate Username field.

Installation Guide
7. In the same NMS HA View, click Generate Keys, and confirm you wish to
generate new security keys. This generates a pair of security keys (private key and public key) for encrypting communications between the Primary server’s system manager and the Secondary server’s system manager. The keys are placed in the SystemManager\conf\keys subfolder of the NetMaster server installation folder. For example: C:\Program Files (x86)\NetMaster\SystemManager\conf\keys
in a Window installation. /usr/NetMaster/SystemManager/conf/keys/
in a Solaris installation. 8. Copy the entire keys subfolder to the SystemManager\conf\ subfolder of the
Secondary server’s installation folder. 9. In the NMS HA View of the Primary server’s System Manager, press Save.
If the HA configuration completes successfully, no error messages appear, and the Save button is greyed out. If the following error is displayed in the dashboard: Something went wrong during mate verification, this indicates that there is a problem/inconsistency with the configuration between the two servers. In that case, verify the following at the Secondary server: Connectivity with the mate Connectivity with DB The correct keys were copied to the correct location 10. In the Dashboard View of the Primary server’s System Manager, verify that HA
Configuration Status is Configuration saved. Note: In the Dashboard View of the Primary server, the HA State will be Active. In the Dashboard View of the Secondary server, the HA State will be Standby.
11. Start the Primary and Secondary servers, by pressing Start in the Dashboard
View of their System Managers. You must start the Primary server first, and wait until it is up and running before starting the Secondary server. Note that in any case where you need to start both the Primary and Secondary servers, you must start the Primary server first, and wait until it is up and running before starting the Secondary server.
12. When logging in, enter in the Server field the addresses of both the Primary
and the Secondary servers, separated by a semicolon.

Securing communications on Windows 1. On both mate machines, install Cygwin with the following packets: unzip, zip,
openssh, openssl and rsync. Refer to http://docs.oracle.com/cd/E24628_01/install.121/e22624/preinstall_req_cy gwin_ssh.htm#EMBSC281. 2. Open the Cygwin terminal as an Administrator, and configure and start the
SSH service as follows (refer also to https://docs.oracle.com/cd/E24628_01/install.121/e22624/preinstall_req_c ygwin_ssh.htm#EMBSC281): a. Configure the SSH service by executing: ssh-host-config. Enter No in response to the query: Do you want to use a different name? (yes/no)
b. After setting up the SSH service the following message should appear: Host configuration finished. Have fun!
c. Start the SSH service by executing the following command: cygrunsrv -S sshd
3. Configure SSH to work between the two mates without a password, by
performing the following in each of the two mate machines:
4. Generate a pair of RSA keys without a password, using the following Cygwin command: ssh-keygen –t rsa.
a. Save the keys in the default folder /home//.ssh/ 5. Copy the public key of each mate machine to the other mate machine, as
follows:
a. In one machine, open the id_rsa.pub file with a text editor, and copy its content, which is this machine’s public key. Ceragon Proprietary and Confidential

b. In the other machine, create an authorized_keys file under C:\cygwin\home\\.ssh\ and paste the copied public key into the file. 6. If any of the mate machines uses SFTP, change the SSH default port to a number other than 22 in the machine’s SSH_config file. 7. In each of the two machines, connect from one computer to another via SSH using: ssh @.
This adds the host to the known_hosts list. 8. In each of the two machines, create a home user directory for the SYSTEM user
as follows: Under C:\cygwin, create a root subfolder, and under root create a .ssh subfolder.
9. Make the owner of the root folder the SYSTEM user by executing the following Cygwin commands: chown SYSTEM /root and chown SYSTEM /root/.ssh. 10. In each of the two machines, copy the private and public keys and the known_hosts file to the root/.ssh/ directory by copying the id_rsa.pub file, the id_rsa file and the known_hosts file from C:\cygwin\home\\.ssh into the C:\cygwin\root\.ssh
folder you created in step (8). 11. In each of the computers, modify the password file in C:\cygwin\etc\passwd as follows: In the line that starts with SYSTEM insert /root before the last colon on the line, and the append /bin/bash after the last colon on the line. 12. For example: SYSTEM:*:18:18:U-NT AUTHORITY\SYSTEM,S-1-5-18:/root:/bin/bash 13. If a passwd file does not exist in the C:\cygwin\etc\ folder, you need to create it by creating in the C:\cygwin\etc\ folder a new file named passwd
(without an extension), and then executing the following command in the Cygwin terminal: mkpasswd –l >> /etc/passwd
3.7.2
Securing communications on Solaris 1. On each mate machine, install rsync with all its dependencies. 2. Configure SSH to work between the two mates without a password, by
generating a pair of RSA keys without a password, in each of the two mate machines. 3. Copy the public key of each mate machine to the other mate machine, as
follows:
a. In one machine, open the id_rsa.pub file with a text editor, and copy its content, which is this machine’s public key. b. In the other machine, create an authorized_keys file under /.ssh/ and paste the copied public key into the file. Ceragon Proprietary and Confidential

4. If any of the mate machines uses SFTP, change the SSH default port to a number other than 22 in the machine’s SSH_config file. 5. In each of the two machines, connect from one computer to another via SSH using: ssh @.
This adds the host to the known_hosts list. 6. In each machine, test rsync as follows: type rsync into a terminal window, and make sure the command is recognized. If instead a command not found message appears, add rsync to the PATH variable by appending /usr/bin/
to the PATH variable.

Installation Guide
NetMaster Database High Availability Database High Availability is intended to ensure continuous NetMaster database operation. In the current NetMaster release R15A01, Database High Availability requires that NetMaster Server High Availability also be enabled. NetMaster offers a database high availability setup, in which two NetMaster databases are configured so that one is the Active database, and the other is the Failover database. At any given time only one of the two databases is active. If the machine hosting the active database is stopped, the server detects the failure and switches to the other (failover) database which then becomes the active database. This switchover may take up to 10 minutes. When the machine that stopped is restarted, the database on that machine becomes the failover database. In a database high availability setup, the currently active database is regularly replicated to the failover database. You can set the replication frequency, with the default frequency being once a day.
4.1
NetMaster Database High Availability configuration instructions Setting up the database high availability solution requires the following: 1. Verifying you follow the Prerequisites to configuring Database High
Availability. 2. Defining certain settings during the initial setup of the Active and Failover
databases. Refer to Initial setup of NetMaster databases participating in database High Availability.
4.2
Prerequisites to configuring Database High Availability
In the current NetMaster R15A01 release, database high availability requires that NetMaster Server High Availability also be enabled. In the current NetMaster R15A01 release, database high availability requires that the NetMaster server be installed on a Solaris machine, and the database be a Postgres database. Both the Active and the Failover databases must be the same Postgres 9.4.x version. Both the Active and the Failover databases must use the same database encoding method: UTF8 or ASCII. Encoding is set during database creation; instructions for how to set the encoding method can be found on the Postgres support site. The Active and Failover databases must have different names.

NetMaster NMS R15A01
Installation Guide
The Active database and Failover database should be installed on separate servers, which do not also host a NetMaster server. That is, installation will include four distinct nodes: two servers hosting the NetMaster high availability servers (one each) and two servers hosting the high availability databases (one each). System Manager must be installed on all servers in which a NetMaster server or database are installed. On both the Active and the Failover database machines, make sure that you add to the pg_hba.conf file the IP address of the other (mate) database, and of the Primary and Secondary NetMaster servers. For example: host host host
all all all
all all all
1.1.1.1/32 1.1.1.2/32 1.1.1.3/32
md5 md5 md5
Where 1.1.1.1 is the IP address of the mate database, 1.1.1.2 is the IP address of the Primary Active NetMaster server, and 1.1.1.3 is the IP address of the Secondary Standby NetMaster server.
4.3
Initial setup of NetMaster databases participating in database High Availability This section describes the steps required for initial setup of NetMaster databases intended to participate in a database high availability setup. These steps must be performed on the System Manager of the NetMaster server. If server high availability is implemented, these steps must be performed identically in the System Manager of each of the two mate servers. The steps, described in Defining the Active and Failover databases and the replication frequency, include the following: 1. Defining two databases – an active database and a failover database. 2. Defining the replication frequency.
4.3.1
Defining the Active and Failover databases and the replication frequency 1. On the System Manager of the NetMaster server, define the active database, as
follows: a. In the Introduction page of the Set Active/Failover User/Schema wizard, set Operation type to Set Active User/Schema.

Note that for Solaris, this path must be manually added. 3. Set the database replication frequency in the Backup Active User/Schema page
of the Backup Active User/Schema wizard, as follows. Note that replications will always be made from the currently Active database to the current Failover database. a. Select the Schedule Backup checkbox, and set the Start date and time, as well as the frequency of the periodic backup. The frequency settings apply also to database replications. b. Select the Database Replication backup checkbox. The replication frequency you set will apply to the database that is the active database at the time replication occurs.

Migration from PolyView to NetMaster
5.1
Overview For PolyView NMS customers that are migrating to the NetMaster NMS, a special tool is provided to import: The managed elements from PolyView into NetMaster (see Importing Topology from PolyView to NetMaster). NetMaster processes the list of elements that were managed by PolyView and carries out the “discovery” and “manage” processes on these elements. The elements are placed in the Geographical or Logical Trees under the same hierarchy that existed in PolyView.
5.2
The PolyView users (not Groups) into the NetMaster (see Importing users from PolyView to NetMaster). The users to be imported into NetMaster are selected from the list of users that were defined in PolyView.
Importing Topology from PolyView to NetMaster You can export discovered elements and subnetworks from PolyView into a file and then import them, while preserving their hierarchy, into NetMaster as managed elements in administrative domains. This can spare you the need to enter all the IP addresses again and create the domain hierarchy manually. Note:
5.2.1
NetMaster supports only IPv4 addresses. Import will not succeed if the network elements in PolyView only have IPv6 addresses.
Step 1: Create a PolyView Export File 1. In the PolyView topology tree, select which part of the network data to export. 2. Select File > Export data. The Export Data window appears.

3. In the Data types area, clear the checkboxes of any data types you wish to
exclude from export.
4. In the File area, enter or browse to the desired output destination path and
filename.
5. Click OK to perform the export.
5.2.2
Step 2: Prepare for Import into NetMaster Before starting the import process, you may want to prepare in any of the following ways:
The topology import process is guided by NetMaster’s default connection templates. To enable the process to discover elements with a custom community name, change the default connection template accordingly.
By default, the import process places elements in the geographical map. However, you can instruct the import process to place the element in the logical map by changing the defaultDomain parameter in the config.properties file, from: defaultDomain = G
to defaultDomain = L
By default, the import process performs all import stages: parsing the import file, discovering elements, creating an administrative domains (AD) tree, and managing the elements. However , you can instruct the import process to perform only some of these stages by setting the processMode parameter of the config.properties file to any of the following values: 0 – only parse the import file and display a summary 1 – parse and discover 2 – parse, discover, and create an AD Tree 3 – parse, discover, create an AD Tree, and manage. This is the default
setting. Note:
5.2.3
The config.properties file is located in the NetMaster installation folder, under .../NetMaster/PolyTopoImport/conf.
Step 3: Run the Topology Import Tool Note:
The topology import tool is located in the NetMaster installation folder, under .../NetMaster/PolyTopoImport.
1. Make sure the NetMaster server is running. 2. Make sure no other discovery or management process is running. Ceragon Proprietary and Confidential

Installation Guide
3. Make sure you have PolyTopoImport permission. Note that all Administrators
group members have this permission.
4. On the computer running the NetMaster server, run the command line tool as
follows: In Windows, run:
polytopoimporter.bat
or polytopoimporter.bat
In Solaris, run: polytopoimporter.sh
or polytopoimporter.sh
where: is the full path and name of the export file. For example: c:\67-68.exp. instructs the tool to place all
hierarchical domains exported from PolyView under: Geographical/subdomain1/subdomain2/subdomain3
or Logical/subdomain1/subdomain2/subdomain3
5.2.4
Step 4: View Import Results After import is complete, you can view a summary of the parsing, discovery and management operations in the console and the log file. The summary lists, for example:
How many IPs were successfully discovered and managed during the import process.
The elements that failed to be managed, together with the reason for failure. You can also view these elements in the Unmanaged Elements view.
The error titles of any errors that occurred. For detailed error information, see the error log.
Note that if the import file contains IPs that are already managed in NetMaster, these IPs are not affected by the import process. These IPs will be reported in the console and the log file.

Installation Guide
Importing users from PolyView to NetMaster Only the root user is allowed to import PolyView users. Only PolyView users can be imported, not PolyView groups. After they are imported, users are assigned to the default group and may be reassigned to other groups. If an imported PolyView user already exists in NetMaster, the existing user's attributes are overwritten by the imported user. Note:
5.3.1
An Admin user cannot be imported from PolyView.
Step 1: Export PolyView User Definitions to a File 1. Select Start > All Programs > PolyView > PolyView Server Security or in
CeraMap, select Settings > Security Settings to open the PolyView server security application.
2. Select File > Export users to save user definitions to a file.
5.3.2
Step 2: Import the User Definitions into NetMaster The views needed here are found in the User Management perspective. 1. In the User Administration view select the Import PolyView Users operation.
An Open window appears, allowing you to select the import file. 2. Navigate to and select the file created in Step 1 above, and click Open. An
Import users window opens.
3. Select the users to be imported and click OK. The new users will appear in the
Users table.
