Type of failure: |
What happens: |
Channel initiator communications subsystem failure |
The channels dependent on the communications subsystem
enter channel retry, and are restarted on an appropriate queue-sharing group
channel initiator by a load-balanced start command. |
Channel initiator failure |
The channel initiator fails, but the associated queue
manager remains active. The queue manager monitors the failure and initiates
recovery processing. |
Queue manager failure |
The queue manager fails (failing the associated channel
initiator). Other queue managers in the queue-sharing group monitor the event
and initiate peer recovery. |
Shared status failure |
Channel state information is stored in DB2(R), so a loss of
connectivity to DB2 becomes a failure when a channel state change occurs.
Running channels can carry on running without access to these resources. On
a failed access to DB2, the channel enters retry. |
