Oracle 10g Installation on Redhat Enterprise Linux | RHEL - 5 Installing Required Packages The Oracle Universal Installer (OUI) performs checks our machine during installation to verify that it meets the appropriate OS package requirements. We have to verify and install all packages (RPMs) required by Oracle Database 10g. An easier method is to run the #rpm -Uvh

.

Required Packages for Oracle 10g R2 on the i386 (32-bit). Login as “root” user and execute package installation command on terminal. Check appropriate disc (If more than one disc) - to set required packages. # cd /media/cdrom/Redhat/RPMS # rpm -Uvh setarch-2* # rpm -Uvh make-3* # rpm -Uvh glibc-2* # rpm -Uvh libaio-0* # rpm -Uvh compat-libstdc++-33-3* # rpm -Uvh compat-gcc-34-3* # rpm -Uvh compat-gcc-34-c++-3* # rpm -Uvh gcc-4* # rpm -Uvh libXp-1* # rpm -Uvh openmotif-2* # rpm -Uvh compat-db-4* # cd / eject It is possible to query each individual package to determine which ones are missing and need to be installed , Check the following command.

Oracle 10g Installation on Redhat Enterprise Linux | RHEL - 5 POINTS TO REMEMBER : If packages are not installed , use the rpm command with -i option install. If anyone wants to upgrade it to the new version, use -U option  Upgrade.  # rpm -ivh setarch-1* and # rpm -Uvh setarch-1* To improve the performance of the software on

Linux systems, should

increase shell limits for the oracle user In limits.conf file . Here , “nproc" is the max no of processes available to the user and "nofiles" is the no of open file descriptors. Finally make sure that there is an entry in /etc/hosts file for your machine like IP

HOSTNAME.DOMAIN

ALIAS

127.0.0.1 192.168.2.15

localhost.localdomain rhel5.linuxserver

localdomain rhelserv

Machine gets started, it will need to know the mapping of some hostnames to IP addresses before DNS can be referenced. This mapping is kept in

the /etc/hosts file. Environment Variable Setup for linux # echo $dispaly # echo env | more or env The string 0.0 identifies a server number and an optional screen number. In $ DISPLAY=localhost:0.0 ; export DISPLAY 0.0 refers to screen zero , on server 0 on the current system. 3.1 would be screen 1 on server three on system "anothermachine".

Oracle 10g Installation on Redhat Enterprise Linux | RHEL - 5 xhost

-

Server access control program for X.

The xhost program is used to add and delete host (computer) names (user names) to the list of machines and users are allowed to make connections to the X server. If access control is enabled ; xhost Access control enabled , only authorized clients can connect

If access control is disabled ; xhost Access control disabled, clients can connect from any host

To disable the access control ; xhost + Allows any host to access X Server.

To enable the access control ; xhost only authorized clients/hosts are allowed.

xhost + hostname Adds hostname to X server access control list. xhost - hostname Removes hostname from X server access control list.

Oracle 10g Installation on Redhat Enterprise Linux | RHEL - 5 Browser based tools in Oracle 10g Oracle 10g comes with two browser-operated database administration features namely Enterprise Manager and iSQL*PLUS. These are automatically installed during Oracle 10g installation. ISQL*Plus iSQL*Plus is a component of the SQL*Plus product. It is a web-based utility similar to the SQL*Plus command line utility for executing SQL and PL/SQL commands. It means a browser-based interface to SQL*Plus. iSQL*Plus is used to write SQL and PL/SQL commands to ,  Enter, edit, run and save SQL commands and PL/SQL blocks.  Calculate, and print query results.  List column definitions for any table.  Access and copy data between databases.  Perform database administration. To Start/Stop iSQL*Plus  $ isqlplusctl start  $ /u01/app/oracle/product/10.2.0/db_1/bin/isqlplusctl start  $ isqlplusctl stop We can invoke iSQL*Plus as a normal user, or with SYSDBA or SYSOPER privileges. When connecting iSQL*Plus to use connect identifier (specifying for which database we want to connect it ). Successful People in life seem to like LINUX

should need a

username and password that identifies as an authorized user. Who wants to connect as sysdba in iSQL*Plus  http://localhost:port/isqlplusdba  Only for sysdba  http://localhost:port/isqlplus  Normal users like scott , hr etc .. Example URLS  SQL*Plus URL  (Normal users)  http://rhel5.myserver:5560/isqlplus  iSQL*Plus DBA URL:  (SYSDBA)  http://rhel5.myserver:5560/isqlplus/dba ISQL*Plus LOGIN PAGE

Oracle 10g Installation on Redhat Enterprise Linux | RHEL - 5 Starting iSQL*Plus $ isqlplusctl start iSQL*Plus 10.2.0.4.0 Copyright (c) 2003, 2005, Oracle. All rights reserved. Starting iSQL*Plus ... iSQL*Plus started. I don’t know how to find iSQL*Plus URL .. How Can I get it ? The iSQL*Plus URL looks like http://machine_name.domain:port/isqlplus http://oel.linuxserver:5560/isqlplus/ http://myserver:5560/isqlplus/ Enter the iSQL*Plus URL in web browser's Location or Address field POINTS TO NOTE iSQL*Plus uses HTTP port 5560 by default. If iSQL*Plus is not available on port 5560, read the $ORACLE_HOME/install/portlist.ini file on the computer running the iSQL*Plus Application Server to find the port on which iSQL*Plus is running. POINTS TO REMEMBER Oracle decided to desupport

iSQL*Plus with the Oracle 11g

release. Users should migrate to SQL Developer instead. Successful People in life seem to like LINUX

Oracle 10g Installation on Redhat Enterprise Linux | RHEL - 5 Installing SQL*Plus Instant Client SQL*Plus is a command line interface to the Oracle Database. SQL*Plus allows to define and manipulate data in oracle database. SQL*Plus is a basic oracle database utility used by Admins/Developers. SQL*Plus recognizes SQL commands and sends these commands to Oracle server for execution. SQL*PLUS OPERATIONS Listing definations of tables. Accessing and transferring data between databases. Execution of SQL commands (Editing/Saving/Loading) and PLSQL blocks. Formatting, saving, printing, calculations on the results of a query in the form of reports. Functions for Oracle database managing like users administration, tablespaces, operations management of archiving and recovery. To Install SQL*Plus Instant Client, we need two Packages: 1 ) SQL*Plus Instant Client package. 2 ) Basic OCI Instant Client package.

(or)

3) The lightweight OCI Instant Client Package.
