I try to apply the Oracle 18.104.22.168 patch to my DB 22.214.171.124. I shutdown down all database and the services with Oracle_xxx. but when the setup program running it raise an error - Certain files which need to be re-installed ... are being used by one or more applications' when the status showing "Processing RDBMS Required Support Files Patc....." at 88%.
Form the message it didn't tell which files/application was inuse.
Is anyway I can find out what file/application are opened. the system is Windwos 2K sp4 / Oracle 126.96.36.199
Any help is much apprecated.
