Information in this document applies to any platform.
In a Grid Infrastructure managed environment (either Grid Infrastructure Standalone a.k.a. Oracle Restart OR Clustered Grid Infrastructure) on Windows, starting a database instance resource takes a very long amount of time (such as 25 minutes).
Further investigation determines that starting Oracle High Availability Services Daemon (OHASD) takes just 1 minute
and starting ASM (ora.asm) also takes just 1 minute, but starting the database instance(s) takes approximately 25 minutes to start.
The Grid Infrastructure alert.log file shows messages such as the following:
After multiple attempts, OHASD brings up the database instance but the start up time is increased to 25 minutes or even longer.
In this case, the issue was observed after a Windows patch was applied and the server was rebooted.
