The following errors occur when adding a standby database to DG:
DGMGRL> add database 'stdby_db' as connect identifier is 'stdby_db' maintained as physical;
Error: ORA-01033: ORACLE initialization or shutdown in progress
Failed.
SOLUTION
Make sure the password file is copied from primary database, and configured properly in RAC:
On standby database server:
$ srvctl config database -d stdby_db
...
..
Password file: <======= password file is not on ASM and will be read from $ORACLE_HOME/dbs instead
Copy the correct password file from Primary’s ASM to the Standby’s ASM and modify the password file path in OCR:
$ srvctl modify database -d stdby_db -pwfile <ASM path for the password file>
