DATABASE UPGRADE FROM 10.2.0.5 TO 11.2.0.1 - DBUA.pdf

UPGRADE ORACLE DATABASE FROM 10g TO 11g - DBUA

UPGRADE DATABASE FROM 10.2.0.5 TO 11.2.0.1 This article is intended as a brief guide to upgrade Oracle Database from 10.2.0.5 to 11.2.0.1 on LINUX OS for Self Practice. I explain step by step how to upgrade database from 10g to 11g. The purpose of this article to minimize the downtime while upgrading the database using DBUA. WHY UPGRADE ?

Several Bugs that are causing outages and/or business impacts? Upgrade your database because numerous Bugs fixed. Several new features deployed with higher versions. Improved Performance and Scalability for latest versions rather than previous versions. Already Thousands of customers upgraded their database from lower versions to recent versions. Extended support fee can be avoided; no bug fixes unless you pay extra fee to get extended support. Upgrade means the process of changing the data dictionary contents of a database to reflect particular release. Upgrading from 10.2.X to 11.2.X is a major release upgrade. Ex: 10.2.0.5.0 to 11.2.0.1.0 Upgrading from 10.2.0.X to 10.2.0.X is a patch set upgrade. EX: 10.2.0.1 to 10.2.0.5

IMPORTANT POINTS BEFORE YOU START 11G UPGRADE

1. Read Chapter 1, 2 & 3 of Database Upgrade Guide here 2. Read 11g online documentation INSTALLING & UPGRADING from here DIFFERENT WAYS TO UPGRADE AN ORACLE DATABASE.

UPGRADE ORACLE DATABASE FROM 10g TO 11g - DBUA

Generally peoples are using MANUAL & DBUA method. But I would prefer to use DBUA method. DBUA

– Database Upgrade Assistant – Recommended by Oracle.

MANUAL – Using SQL scripts and utilities. WHEN TO CHOOSE DBUA ?

Remains same operating system as well as at least 90 mins avg downtime. GUI is preferred rather than command line interface because, Less manual effort & automatically performs pre-upgrade checks. CONSIDERATION

Source & Target $ORACLE_HOME should reside in same system. Cannot rerun if any error encountered mid-upgrade. DBUA automates the upgrade process by performing all of the tasks which are performed manually. Some steps which can be performed when the database is running. If these steps can be done manually before upgrading using DBUA, the downtime can be minimized. ABOUT DBUA

It provides GUI Mode – Graphical User Interface. Recommended method to perform Database upgrade (major release). Automates the upgrade process by performing all of the tasks. DBUA makes appropriate recommendations for configuration options such as tablespaces & redologs.

DBUA PERFORMS FOLLOWING CHECKS BEFORE UPGRADE PROCESS

Stale optimizer statistics. Invalid user accounts or roles. Invalid data types or invalid objects. Desupported character sets. Timezone file versions. Adequate resources, including rollback segments, tablespaces, and free disk space Missing SQL scripts needed for the upgrade. Listener running (If OEM database control upgrade or configuration is requested). Oracle Database Software linked with Database vault option. If database vault is enabled, DBUA will ask you to disable Database vault before upgrade. ** DBUA does NOT begin the upgrade until all of the pre-upgrade steps are completed. **

FIX DUPLICATE OBJECTS

Check for duplicate objects in SYS and SYSTEM schemas. Ensure that you do NOT have duplicate objects in the SYS and SYSTEM schema. SYS> select OBJECT_NAME, OBJECT_TYPE from DBA_OBJECTS where OBJECT_NAME||OBJECT_TYPE in (select OBJECT_NAME||OBJECT_TYPE from DBA_OBJECTS where OWNER='SYS') and OWNER='SYSTEM';

PACKAGE BODY

Please refer 1030426.6 how to clean up duplicate objects owned by SYS & SYSTEM schema. I would not be clean anything from SYS & SYSTEM schema. IMO, it is safe to leave above items as it is. INSTALL 11g ORACLE DATABASE SOFTWARE

Download 11g Software from here. 

Transfer files to target server and unzip those files.



Install 11g s/w in separate location.



Step by step 11g installation on OEL explained here.

UNZIP DOWNLOADED FILES

# First unzip file1 then unzip 2nd file. Do not unzip parallelly both files. $ cd /u04/software $ unzip linux_11gR2_database_1of2.zip $ unzip linux_11gR2_database_2of2.zip Once you unzip both files, you will get database directory; then need to change the ownership of that s/w or else set the appropriate permissions to oracle user to install the database s/w. INSTALL 11g SOFTWARE ON NEW MOUNT POINT

$ mkdir –p /u01/app/oracle/product/11.2.0/db_home

# In my case, 11g S/W already installed.

WHY SEPARATE $ORACLE_HOME FOR 11g

We cannot upgrade existing 10g $ORACLE_HOME for 11g database. 11g is NOT a Patchset. We have to install 11g $ORACLE_HOME separately. To upgrade existing database into 11g, install only Oracle 11g Server software into new location. $ORACLE_HOME for 10g : /u02/app/oracle/product/10.2.0/db_home $ORACLE_HOME for 11g : /u01/app/oracle/product/11.2.0/db_home

# ANY INVALID OBJECTS, EXECUTE FOLLOWING SCRIPT. SYS> @?/rdbms/admin/utlrp.sql; ... Should be NO invalid objects from SYS and SYSTEM schema. Recompile all invalid objects using utlrp.sql before upgrade process

CHECK ANY FILES IN MEDIA RECOVERY

SYS> select * from v$recover_file; no rows selected. SYS> select * from v$backup where status != 'NOT ACTIVE'; no rows selected. Make sure no files need media recovery as well as nothing is in backup mode. GATHER DICTIONARY STATS

In order to reduce the amount of downtime, you can collect statistics prior to perform actual database upgrade. As of 10g Oracle Database, Oracle recommends to use DBMS_STATS procedure to gather statistics. This procedure gather statistics for dictionary schemas SYS, SYSTEM, etc..

# STATISTICS FOR ALL DICTIONARY OBJECTS SYS> EXEC DBMS_STATS.GATHER_DICTIONARY_STATS; ... If you ignore to keep stats up to date on data dictionary, then updating itself time taking process. Oracle recommends collect stats on you dictionary as part of pre-upgrade task prior to downtime. CHECK ANY CORRUPTION IN THE DICTIONARY

# EXECUTE AS SYS SCHEMA SYS> spool analyze.sql; SYS> SELECT 'Analyze cluster "'||cluster_name||'" validate structure cascade;' FROM dba_clusters WHERE owner='SYS' UNION SELECT 'Analyze table "'||table_name||'" validate structure cascade;' FROM dba_tables WHERE owner='SYS' AND partitioned='NO' AND (iot_type='IOT' OR iot_type is NULL) UNION SELECT 'Analyze table "'||table_name||'" validate structure cascade into invalid_rows;' FROM dba_tables WHERE owner='SYS' AND partitioned='YES'; SYS> spool off;

ORACLE DATABASE VAULT

If you have enabled Oracle Database vault option in your current home, you must disable it. If you do not disable it, DBUA will return an error to disable prior to upgrade. # CHECK ORACLE DATABASE VAULT IS ENABLED OR NOT SYS> select * from v$option where parameter='Oracle Database Vault'; PARAMETER

FALSE

NOTE 453903.1 – Enabling and Disabling Oracle Database Vault in UNIX.

BACK UP ENTERPRISE MANAGER DATABASE CONTROL DATA

You may ignore this action. After upgraded to 11g, suppose you decide to downgrade from 11g to 10g then direct downgrade of EM is not supported. So it is better to save the EM data and restore it back. The utility emdwgrd can be used to keep a copy of database control files and data before upgrading your database. It resides in $ORACLE_HOME/bin directory. Please refer 870877.1. RUN PRE-UPGRADE INFORMATION SCRIPT

Copy the Pre-Upgrade information script (utlu112i.sql) from 11g $ORACLE_HOME/rdbms/admin/ into /tmp directory and start SQL*Plus. Execute the script. This script checks the database (which you want to upgrade to 11g R2) and reports any changes need to be done before the upgrade process.

Adjust the warnings reported by the utlu112i.sql script. I have fixed following warnings prior to upgrade with help of oracle docs.

FIX THE WARNINGS REPORTED BY PRE-UPGRADED TOOL

If the current database contains objects with stale optimizer statistics, then it would be better to collect the statistics before upgrade process. If we ignore upgrade process will be slower depending upon number of objects with stale optimizer statistics.

Pre upgraded scrip reported some tablespaces need adequate space for upgrade process; they can automatically extend by itself, if auto extendable option is enabled for those tablespaces. Using above SQL statement you can verify which tablespaces have auto extend option.

Exploring the Oracle DBA Technology by Gunasekaran ,Thiyagu

UPGRADE ORACLE DATABASE FROM 10g TO 11g - DBUA

If auto extend clause is not enabled, you can resize the tablespace at command line. As per warnings, you need to resize required tablespaces to set sufficient space.

# EXAMPLE FOR RESIZING SYSTEM DATAFILE SYS> alter database datafile '/u02/app/oracle/oradata/devdb/system01.dbf' resize 1000m; ... MISCELLANEOUS WARINGS

You can see bunch of various warnings about the current database. Even you ignore them, they may make the upgrade to run slower and may effect some of Oracle features that you use. You need to take care some warnings prior to upgrade and some after the upgrade.

When you create a listener on a NON DEFAULT PORT, PMON tries to register the database service(s) with this listener. PMON utilizes TNSENTRY naming method for this. PMON will look in tnsnames.ora file for the value it found in LOCAL_LISTENER. If it does not find this entry in the tnsnames.ora file, it will throw error.
