What is Patch and Why we need to apply Patch??
Patch: To add new features to the existing environments with modifying simple codes in the background, Vendor will release patches instead of next version.
Why Patch: After releasing version, may vendors got response from users or clients like they are facing issue in using some features. Those might be bugs in that version. So, Development Team will work on those bugs and Vendor will release Patch to add the functionality to the existing version.
Now, Main part in patching.....!!!! How to apply Patch??
Go to Oracle My Support and search for Patches.
Click on Read Me, to get patch instructions.
Here also, i am briefing how to apply
Download and unzip to the following path, (Change Drive name as per your environment)
C:\Oracle\Middleware\EPMSystem11R1\OPatch
As Mentioned in Read Me, first see Prerequisites before applying patch.
for example, we have FDM in our environment, for this we need to change Enable 32bit application to false in IIS.
Go to Command Prompt and change path to OPatch Location and execute the Opatch as mentioned in Read Me.
and we get result as OPatch Succeeded.
Now my 11.1.2.3 environment patched with 500 patch.
Thanks,
