Why should we use this utility:
We should use this utility so that each and every entry will be removed which was created while installing the ORACLE_HOME, if we will directly remove the ORACLE_HOME using OS Commands, we may face further issues of the oracle configuration.
Because when we install Oracle Software many files gets created and updated accordingly, so going to each file and delete the entry for this new software will be cumbersome and time consuming. So the faster and safer solution is to use this utility.
First of go to Oracle Site and Download the De-install Utility:
Above link is for Sparc Solaris 64 bit version.
Software name would be like this: solaris64_11203_deinstall.zip
Use WinScp or any other software to place this on Solaris Server. I have placed it under (/u06/oracle/software/11g/deinstall/) and unzip the software which will create a “deinstall” directory in the same folder.
bash-3.00$ ls -lrt
total 283600
drwxr-xr-x 20 oracle dba 512 Sep 30 2011 deinstall
-rw-r–r– 1 oracle dba 145111670 Oct 16 14:08 solaris64_11203_deinstall.zip
bash-3.00$
Go to deinstall directory and locate the utility:
bash-3.00$ cd deinstall/
bash-3.00$
bash-3.00$ ls
assistants crs deinstall diagnostics lib oui response sysman
bin cv deinstall.pl jlib logs perl srvm usm
bootstrap.pl dc_ocm deinstall.xml jre mapfiles readme.txt sshUserSetup.sh utl
bash-3.00$
Before we run this utility, i would like to mention the fact that using this utility we can remove the ORACLE_HOME while putting the option -home with this utility.
Here in this example i am uninstalling the ORACLE_HOME=/u01/app/oracle/product/11.2.0.3/.
This directory – /u01/app/oracle/product/11.2.0.3/ contains the whole software.
Run the utility with the ORACLE_HOME from the deinstall directory:
bash-3.00$ ./deinstall -home /u01/app/oracle/product/11.2.0.3/
Location of logs /u01/app/oracle/oraInventory/logs/
