1.1 Accessing WebSphere MQ With and Without the Tuxedo MQ Adapter

WebSphere MQ is an XA compliant resource manager, and it is possible to access WebSphere MQ directly from Tuxedo server programs that issue MQ APIs such as MQGET and MQPUT1. Such server programs can be placed in a group associated with the WebSphere MQ Resource Manager, and no adapter program is required to access such servers.

Some customers have existing WebSphere MQ programs that they want to access from Oracle Tuxedo without having to modify their MQ programs or to write any MQ code on the Tuxedo side of their applications. For these customers, Oracle has developed the MQ Adapter for Tuxedo. The Oracle MQ Adapter for Tuxedo supports both transactional and non-transactional access to WebSphere MQ applications and data.
