Database altered.
SQL> select open_mode from v$database;

if I disable the system triggers using
ALTER SYSTEM SET "_system_trig_enabled"=FALSE scope=both;
The error doesn't appear but when trying to switch to active dataguard the open_mode goes from READ ONLY to MOUNTED rather than READ ONLY WITH APPLY
Any help much appreciated

Answer 1

Have you checked what your guard status is set to?
SQL> SELECT guard_status from v$database;I've had a similar issue before but with a standby, whereby the status was set to ALL. This means all users apart from SYS are unable to make changes on the database.
My resolution was to set the status to standby:
SQL> ALTER DATABASE GUARD STANDBY;You may wish to set the guard status to NONE however.
I took some notes:
