the Oracle Restart stack produces a shutdown abort..
I was unable to find official documentation about that (expect for crsctl stop crs which causes a ASM shutdown abort , that is in RAC case. )
Is it an expected behaviour or is something like a bug?
Yes , thanks it explains crsctl stop commands should be
used as emergency procedure to stop ASM or databse and that a shutdown immediate on a database could provide an unwanted delay.
Anyway, as both database and ASM are Oracle Restart managed resources it's pretty strange that
while asm shutdown is fine , database is not.
