Failover Testing

Failover testing is a testing technique that validates a system's ability to be able to allocate extra resource and to move operations to back-up systems during the server failure due to one or the other reasons.

Run the following commands on server 1 and server 2 for failover testing:

On Server 1

dspmq -x -o standby

QMNAME(MQT24)                         STANDBY(Permitted)
INSTANCE(Host1) MODE(Active)
INSTANCE(Host2) MODE(Standby

On Server 2

dspmq -x -o standby

QMNAME(MQT24)                         STANDBY(Permitted)
INSTANCE(Host1) MODE(Active)
INSTANCE(Host2) MODE(Standby

On Server 1

endmqm -is MQT24

Waiting for queue manager 'MQT24' to end.
WebSphere MQ queue manager 'MQT24' ending.
WebSphere MQ queue manager 'MQT24' ended, permitting switchover to a standby
instance.

dspmq -x -o standby

QMNAME(MQT24)                                             STANDBY(Permitted)
INSTANCE(Host2) MODE(Active)

On Server 1

dspmq -x -o standby

QMNAME(MQT24)                                             STANDBY(Permitted)
INSTANCE(Host2) MODE(Active)

On Server 1

strmqm -x MQT24

WebSphere MQ queue manager 'T24QM1' starting.
The queue manager is associated with installation 'Installation1'.
A standby instance of queue manager 'T24QM1' has been started. The active
instance is running elsewhere.

dspmq -x -o standby

QMNAME(MQT24)                         STANDBY(Permitted)
INSTANCE(Host2) MODE(Active)
INSTANCE(Host1) MODE(Standby

On Server 2

dspmq -x -o standby

QMNAME(MQT24)                         STANDBY(Permitted)
INSTANCE(Host2) MODE(Active)
INSTANCE(Host1) MODE(Standby

Testing Failover in MQ Explorer

You can test the failover in MQ explorer using the following procedure.

1. Open MQ Explorer.

   

2. In the menu on the left, expand IBM WebSphere MQ. Right click Queue Managers and select Add remote Queue manager.
3. Specify Queue manager name and click Next.

   

4. Select the Is this a multi-instance queue manager? check box and specify the IP address of server 1 and 2.

   

5. Click Finish.

   

6. In the menu on the left, click IBM WebSphere MQ > Queue Managers > MQT24 on '10.9.237.185(1414)' and select a queue.
