Oracle database Upgrade from 10.2.0.2 to 10.2.0.4

Hi All,

When we upgrade database from 10g to 11g ,

Firstly check the database of 10g if it is 10.2.0.2 then need to upgrade 10.2.0.2 to 10.2.0.4.

I have create a document for this. Please see the details.

Oracle database Upgrade from 10.2.0.2 to 10.2.0.4

Prerequisites and Precautionary actions before starting DB Upgrade:

1) Take a backup of the Oracle database: Online or Offline

2) Take a file system level backup of 102_64 Directory

     Tar command or backup command or even cp (Recursive) is

     recommended for oracle binary backup as it will back up the links and

     Permissions of the binaries

     Example:

     tar –cvf 102_64.tar ./oracle/<SID>/102_64

                                 OR

     cp –pR /oracle/<SID>/102_64 /backup  

3) Download the Oracle Patch Set 10.2.0.4 from SAP Service Market place

     https://websmp209.sap-ag.de/patches > Database Patches (from other vendors)

     Add the four BIN files to the download basket as shown below and download it

4) Copy the files to the DB Server (AIX) :

Ftp the downloaded files to Server where DB Instance runs:

Directory should have 10 GB Free space (check by du –g command)

Patchset_10204_AIX5Laa.bin

Patchset_10204_AIX5Lab.bin

Patchset_10204_AIX5Lac.bin

Patchset_10204_AIX5Lad.bin

Concatenate the four files using cat command

Example:

cd /oracle/Oraclepatchset

“cat Patchset_10204_AIX5Laa.bin Patchset_10204_AIX5Lab.bin

Patchset_10204_AIX5Lac.bin Patchset_10204_AIX5Lad.bin >> Orapatch.zip”

     unzip Orapatch.zip    # this will create the Oracle Patch directory “Disk1”

Change the ownership of the directory to oracle user and dba group

“chown –R ora<sid>:dba Disk1”  as root user

4) Download Opatch tool and all the Opatch available from SAP SMP and copy the

files to a directory in the DB Server and unzip the files using unzip command

Example:

unzip p5561212_10204_AIX5L.zip
