[V9.1.0 Jul 2018][z/OS]

New IBM MQ 9.1.0 features for z/OS

For IBM® MQ 9.1.0, IBM MQ for z/OS® delivers a number of new features and enhancements that are available with base product entitlement, and with Advanced entitlement. These features include an updated IBM MQ resource adapter, improved workload balancing options for shared queues, and the ability, with the IBM MQ for z/OS Service Provider for IBM z/OS Connect Enterprise Edition, to process requests arriving through IBM z/OS Connect EE.

Additional support for messaging within CICS Liberty JVM server

IBM MQ 9.1.0 provides an updated IBM MQ resource adapter, which has support to allow connections from the CICS® JVM server Liberty profile to IBM MQ, using either client or bindings mode. This additional support for messaging that the resource adapter now provides has a dependency on the CICS Liberty JVM server profile environment. For more information, see Using IBM MQ classes for JMS in a CICS Liberty JVM server.

IBM MQ for z/OS Service Provider for IBM z/OS Connect Enterprise Edition

From IBM MQ 9.1.0, IBM MQ for z/OS Service Provider for IBM z/OS Connect Enterprise Edition (MQ Service Provider) processes requests arriving through IBM z/OS Connect Enterprise Edition (IBM z/OS Connect EE). The MQ Service Provider allows REST aware applications to interact with z/OS assets, that are exposed using IBM MQ for z/OS queues and topics. You can achieve this without having to worry about the coding required to use asynchronous messaging. For more information, see IBM MQ for z/OS Service Provider for IBM z/OS Connect EE.

IBM MQ for z/OS Unix System Services Web Components feature

From IBM MQ 9.1.0, if you want to use the IBM MQ Console, or the administrative REST API to IBM MQ for z/OS you need to install this feature.

Note that to install this feature, you must install the IBM MQ for z/OS Unix System Services Components feature.

See Create and customize the IBM WebSphere® Liberty Profile server definition and Create a procedure for the IBM WebSphere Liberty Profile server for information on how you set up the feature.

Improved workload balancing options for shared queues

IBM MQ for z/OS queue sharing groups can take advantage of a new configuration option provided by the coupling facility which can, in some configurations, improve the distribution of workload, and minimize the number of empty MQGET calls. For more details see Tuning coupling facility list monitoring.
