What's changed in IBM MQ 9.1.0 Fix Pack 1

New -caseno parameter for the runmqras command

The -caseno parameter is equivalent to -pmrno, except it allows a valid Salesforce case number to specified. -caseno or -pmrno are both optional parameters, but it is not permitted to supply both together. For more information, see runmqras (collect IBM MQ diagnostic information).

Behavioral changes to IBM MQ client connections

From IBM MQ 9.1.0 Fix Pack 1, there are a number of minor changes to the way in which a client channel connects to a queue manager. The changes are most specifically in the interactions between security exits and the application of CHLAUTH mapping rules. For more information, see the technote Behavioral changes to MQ client connections introduced by APAR IT25839.
