I am aware that Windows Services can "lock" Oracle DLL's and that this can prevent a successfull Opatch, even after stopping all Oracle services. Some examples: "VMware tools", "Microsoft Monitoring Agent", "Windows Management Instrumentation", virus scanner.
So i have a complete list of services to stop before I can start Opatch.
However, since the july 2019 PSU for Oracle 18 i am having trouble with one new DLL that will stay in use after stopping all known services: ORAEVRUS18.DLL
Verifying environment and performing prerequisite checks...
Prerequisite check "CheckActiveFilesAndExecutables" failed.
The details are:
Following files are active :
D:\oracle\product\18.0\bin\ORAEVRUS18.dll
UtilSession failed: Prerequisite check "CheckActiveFilesAndExecutables" failed.
Log file location: D:\oracle\product\18.0\cfgtoollogs\opatch\opatch2019-10-25_16-11-23PM_1.log
OPatch failed with error code = 73
Anyone knows what process or service locks this DLL?
