this is a 11gr2 RAC ASM instance. when RAC is up and an import is loading data to database, I log onto ASM sqlplus / as sysasm, then 'select name from v$database', I got 'ora-01507: database not mounted'.
when I 'select user from dba_users', I got 'ora-01219: database not open: queries allowed on fixed table/views only'.
1. I dont think the ASM instance should be in not mounted status when RAC is up, am I wrong here?
2. As we still can import data to the database, that means ASM diskgroup mounted and worked
3. After I added all 8 nodes to OEM 12cr2 and promoted them, All associated targets like listeners, database instances etc are promoted, but ASM instance in a 'down' status
My question is 'Should ASM instance stay in 'not mounted' or not?' if yes, is there any other reason that OEM can not prompt these ASM instance.
