Display Status of Management Instances (mgmtStatus)

The mgmtStatus command displays status information for the management instances. 

ttGridAdmin mgmtStatus

(Also see Examine Management Instances (mgmtExamine). The mgmtExamine command recommends actions to repair any reported problems with the management instances.)

Examples

% ttGridAdmin mgmtStatus
Host        Instance  Reachable RepRole(Self) Role(Self) Seq RepAgent RepActive
----------- --------- --------- ------------- ---------- --- -------- ---------
mysys1host  gridmgmt1 Yes       Active        Active     554 Up       Yes
mysys2host  gridmgmt1 Yes       Standby       Standby    554 Up       No

For each instance displayed:

  • Host and Instance show the name of the instance and the name of the host where it is located.

  • Reachable indicates whether the command was successful in reaching the instance to determine its state.

  • RepRole(Self) indicates the recorded role, if any, for the instance in replicating data between management instances.

  • Role(Self) indicates the recorded role, if any, for the instance.

  • Seq is the sequence number of the most recent change on the instance. If the Seq values are the same, then the two management instances are synchronized; otherwise, the one with the larger Seq value has the more recent data.

  • RepAgent indicates whether the replication agent is running on the instance.

  • RepActive indicates whether changes by the mgmtStatus command to management data on the instance were successful. The mgmtStatus command attempts to modify management data on each management instance, but this will not work on the standby management instance, which is read-only.

  • Message has any further information about the instance. (For brevity, this column is not shown in the example.)
