Thanks a lot Bashar.It fixed problem.Please help me to understand.
So shall we have to update snapshot everytime we do patch analysis?My understanding is adpatch utility will upadate snapshot after patching.
Manual refresh is taking around 2 hours.
Maybe you never ran maintain snapshot information manually since you installed or upgraded your current system.
Try applying another patch and then run the patch wizard for a patch that contains a more recent version of one of the files delivered by the first one.
