Hi

I am using MQ client enviornment and connecting to MQ server machine through use of MQSERVER enviornment variable. If after MQREAD(), i want to rollback the read, how i can do ? I can't use MQBEGIN() in client enviornment.
Thanks
Gyan

Location: US: west coast, almost. Otherwise, enroute.

The APR confirms that MQBEGIN is not supported from a client.

The MQBEGIN call is used when you application intends to coordinate a global unit of work - a UofW that includes MQ calls and, for example, DB2 calls.

If you app only intends to commit/rollback MQPUTs and MQGETs, you will use MQCMIT to commit the MQ calls, and MQBACK to rollback.
