Hello,
I am facing an issue with dataguard on my oracle.
The dataguard observer is running on a separate host - other than the primary and the standby/auxillary.
Find the commands output as below.
-------------------------
DGMGRL> show configuration verbose
Configuration - SID
Protection Mode: MaxAvailability
Databases:
SID_HOSTNAME - Primary database
Error: ORA-16820: fast-start failover observer is no longer observing this database

---------------------------------------------------
Now My doubt is to start the observer , should i login into the observer host or i can start it from either the primary or standby.
If i can start it from one of these (prim/stby) ,can i do this as below:
------> % dgmgrl -logfile observer.log / "start observer"
-------> START OBSERVER; from DGMGRL prompt;
Please help me on this.
Thanks and regards,
uday.
