Error: ORA-16820: fast-start failover observer is no longer observing this database

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

    SID_HOSTNAME - (*) Physical standby database

      Error: ORA-16820: fast-start failover observer is no longer observing this database

  (*) Fast-Start Failover target

  Properties:

    FastStartFailoverThreshold      = '240'

    OperationTimeout                = '30'

    FastStartFailoverLagLimit       = '30'

    CommunicationTimeout            = '180'

    ObserverReconnect               = '0'

    FastStartFailoverAutoReinstate  = 'TRUE'

    FastStartFailoverPmyShutdown    = 'TRUE'

    BystandersFollowRoleChange      = 'ALL'

    ObserverOverride                = 'FALSE'

    ExternalDestination1            = ''

    ExternalDestination2            = ''

    PrimaryLostWriteAction          = 'CONTINUE'

Fast-Start Failover: ENABLED

  Threshold:          240 seconds

  Target:             SID_STDBYHOST

  Observer:           thirdhost _observer

  Lag Limit:          30 seconds (not in use)

  Shutdown Primary:   TRUE

  Auto-reinstate:     TRUE

  Observer Reconnect: (none)

  Observer Override:  FALSE

Configuration Status:

ERROR

--->

DGMGRL> show configuration

Configuration - sid

  Protection Mode: MaxAvailability

  Databases:

    sid_primary - Primary database

      Error: ORA-16820: fast-start failover observer is no longer observing this database

    sid_stdby - (*) Physical standby database

      Error: ORA-16820: fast-start failover observer is no longer observing this database

Fast-Start Failover: ENABLED

Configuration Status:

ERROR

---------------------------------------------------

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.
