CBR7530E OAM degraded. DB2 is not available. Start DB2.

Explanation
 DB2® is not
available; therefore, there is no way to access the optical configuration
database. The operator is required to start DB2. Once DB2 has
been started, OAM will attempt to reconnect to DB2. If this reconnection attempt fails MULTIPLE
times, the operator may need to cancel OAM.
 All OAM commands, including START OAM, DISPLAY OAM,
and MODIFY OAM,RESTART, will be unresponsive until DB2 has been restarted. If DB2 cannot be restarted, the CANCEL OAM command
can be used to terminate OAM. However, CANCEL should be a last resort
because it can cause unexpected results. 

System action
 Withhold all requests of the Database Manager
until DB2 is available.

Operator response
 START DB2 to continue OAM object processing or CANCEL OAM to terminate
OAM.
