How to Upgrade Oracle Database 11.2.0.1 to 11.2.0.4 ?

Upgrade Oracle Database 11g

=================================================

===============

Database upgrade important part of DBA life . So when doing upgrade database we make note some important point :-

1. Verify all the prerequisite h/w  and s/w  for target version .

2. Use out of place upgrade method (recommended by oracle  ) 

3. Take backup of existing database which going to upgrade and  keep backup  if possible on another     server (mount point  like /bkp)

   use RMAN (Recovery manager) to take full  backup of database 

 Step 1:
============

Download Software from Oracle site.

Oracle Database (includes Oracle Database and Oracle RAC) Note: you must download both zip files to install Oracle Database.	p13390677_112040_platform_1of7.zip p13390677_112040_platform_2of7.zip
Oracle Grid Infrastructure (includes Oracle ASM, Oracle Clusterware, and Oracle Restart)	p13390677_112040_platform_3of7.zip
Oracle Database Client	p13390677_112040_platform_4of7.zip
Oracle Gateways	p13390677_112040_platform_5of7.zip
Oracle Examples	p13390677_112040_platform_6of7.zip
Deinstall	p13390677_112040_platform_7of7.zip

We need for Database:

p13390677_112040_platform_1of7.zipp13390677_112040_platform_2of7.zip




After unzip  the downloaded software :-

unzip  p13390677_112040_platform_1of7.zip
unzip p13390677_112040_platform_2of7.zip




Step 2:
==================

Click on runInstaller and install software  with new oracle home 





Step 3:
=================
After  software install  run pre-check before upgrade on running database using new oracle home  run the prerequisite script

SQL> @/u01/app/oracle/product/11.2.0.4/db_1/rdbms/admin/utlu112i.sql

SQL> !pwd

Miscellaneous Warnings

**********************************************************************

WARNING: --> Database is using a timezone file older than version 14.

.... After the release migration, it is recommended that DBMS_DST package

.... be used to upgrade the 11.2.0.1.0 database timezone version

.... to the latest version which comes with the new release.

WARNING: --> Your recycle bin is turned on and currently contains no objects.

.... Because it is REQUIRED that the recycle bin be empty prior to upgrading

.... and your recycle bin is turned on, you may need to execute the command:

        PURGE DBA_RECYCLEBIN

.... prior to executing your upgrade to confirm the recycle bin is empty.

WARNING: --> Database contains schemas with objects dependent on DBMS_LDAP package.

.... Refer to the 11g Upgrade Guide for instructions to configure Network ACLs.

.... USER APEX_030200 has dependent objects.

.

**********************************************************************

Recommendations

**********************************************************************

Oracle recommends gathering dictionary statistics prior to

upgrading the database.

To gather dictionary statistics execute the following command

while connected as SYSDBA:

    EXECUTE dbms_stats.gather_dictionary_stats;

**********************************************************************

Oracle recommends reviewing any defined events prior to upgrading.

To view existing non-default events execute the following commands

while connected AS SYSDBA:

  Events:

    SELECT (translate(value,chr(13)||chr(10),' ')) FROM sys.v$parameter2

      WHERE  UPPER(name) ='EVENT' AND  isdefault='FALSE'

  Trace Events:

    SELECT (translate(value,chr(13)||chr(10),' ')) from sys.v$parameter2

      WHERE UPPER(name) = '_TRACE_EVENTS' AND isdefault='FALSE'

Changes will need to be made in the init.ora or spfile.

SQL>

In  above output all component all valid state and check all recommendation by this script

Check db must be running using spfile

-------------------------

Set the display 

export DISPLAY=yourip :0.0

then run xclock its show popup 

Run the ./runinstaller  from command prompt

We skip this step click on netxt

We not provide support email id then show the error ignore this error click on yes

select Skip software and click on next

For upgrade select install database software only then click on next

As per  environment we select type of database 

In my case stand alone single instance database so we select single instance database installation then click on next 

select the language as  per requirement in my case is English then click on next

Choose  which database edition need to install in my case choose Enterprise Edition
then click on next

Define the Oracle Base and Software directory here we careful  when give directory locations
then click on next

we use new home here
/u01/app/oracle/product/11.2.0/db_1/

Select group then click on next

check prerequisite must be check all package are install and meet software requirement
then click on next

In my case swap alert i am ignore all here but  must be validate in environment
Then click on next

Check all parameter which you give before  parameter you define validate then click next

Here software is almost install then popup  on execute Root Script

We login from root user and run script show on popup
after successful  run root.sh click on ok .

then click on close

This stage software installation done we start upgrade database 

Start Upgrade database

====================

We set some env. variable 

set ORACLE_HOME new oracle oracle home which we install 

set display

$export DISPLAY=yourip:0.0

check umask value should be 022

cd u01/app/oracle/product/11.2.0/db_1//bin

and run ./dbua

check =>umask 022

check =>xclock

Execute dbua from new oracle home

click on next

Here we select which database need to be upgrade then click on next

Check here warning then click on next

Here select appropriate value and degree of parallelism  as per env. here we take 1

if you upgrade time zone tick on timezone  dbua also recommend to take backup if need then ypu specify backup location then click on next

Here choose do not move database files as Part of upgrade

if you move file system to ASM so choose as per requirement
then click on next

check  report after upgrade report all components are show successful .

then you login the database from new ORACLE_HOME

check the /etc/oratab file

change .profile in unix/aix .bash_profile in linux set new oracle home location


Enjoy!!!
