Environment:
Standalone database 19c (19.0.0.0) running on ASM instance with a remote physical standby database on WINDOWS 2012 R2 operating system. Oracle restart configured on the servers.
Problem:
1- Best way to stop Oracle components ? i.e. when I am using "srvctl" commands or "sys" and "sysasm" user to stop database and ASM instance the windows services still showing "running" status.
2- Do I need to first patch "GRID home" and start ASM service and then patch "database" home like RAC OR patch "GRID home" and "DB home" at the same time while all services are in stop state ?
In APRIL security patch read me file, it talks about RAC database procedure and DB standalone procedure but not talk about standalone DB running on ASM.
Plus in ready only file it says, apply patch first in standby environment then in PRODUCTION is it compulsory ? or we can apply patch first in Production and then on standby after testing the application ?
Any help would be appreciated.
