Script For Checking The Environment Before Opatch Operations

The script, “deopatch.bat” is a precheck for the 10.2.0.X.X opatch.
This script will check the environment settings which are required for executing opatch and also provide some recommendations.
This script can be executed as a precheck before performing any of the inventory operations such as patch apply, patch rollback, lsinventory, etc.
This script can also executed to find the problem if opatch fails with any environment settings and will display detailed information about the reason for failure. According to the reason for failure, recommendations are also displayed.
This script also shows the detailed information about how opatch is checking and setting the environment variables, java etc.
This script will not perform the actual inventory operation which opatch is doing, but will do the check if all the settings are correct for opatch to proceed.
Software Requirements/Prerequisites
This script can be invoked from the command prompt in Windows.
Configuring the Script
The name of the batch file is “deopatch.bat”.
You can download and keep the script in any location.
Running the Script
This script will not perform the actual inventory operation which opatch is doing, but will do the check to see if all the settings are correct for opatch to proceed.
This script can run in the same way as opatch is executed. For example: To apply a patch: The opatch command is : “opatch apply”.
So opatch will first check if :
> All the environment variables are set
> Opatch is able to find the location of “java”
> Also if java.exe exists in the java location.

If opatch is able to find java, the opatch will proceed with the java operations for applying the patch. If opatch is not able to do the same the opatch will error out accordingly.
You can execute the script “deopatch” in the same way if opatch fails with above checks or before executing the opatch.

The command is : “deopatch apply”
“deopatch” will do all the above mentioned checks and will display the result if you can proceed with the opatch apply. If any errors found “deopatch” will give recommendations accordingly for rectifying the error

This script will check the following:

All the environment variables are set
If ORACLE_HOME is set in the environment
If ORACLE_HOME is specified using “-oh”
If java location is specified using “-jdk”
If java location is specified using “-jre”
If java location is found under ORACLE_HOME\jdk
If java location is found under ORACLE_HOME\jre
If java location is found under ORACLE_HOME\jre then the version is greater than or equal to 1.4
If java location is found under ORACLE_HOME\oui\oraparam.ini
If java location is found then does “java.exe” exists in the java location.
Also display the version of java.
