Preparing CICS application programs in AIX

Use this information when preparing CICS programs in AIX .

Use XA switch modules to link CICS with IBM MQ . For more information on the XA switch structure, see The XA switch structures.

The sample source code file is provided to enable you to develop the XA switches for other transaction messages. The name of the switch load module provided is listed inTable 1.

Description	C (source)	C (exec) - add to your XAD.Stanza
XA initialization routine	amqzscix.c	amqzsc - CICS for AIX

Use the prebuilt version of the IBM MQ switch load file amqzsc, which is provided with the product.

Always link your C transactions with the threadsafe IBM MQ library libmqm_r.a., and your COBOL transactions with the COBOL library libmqmcb_r.a..

We can find more information about supporting CICS transactions in the Administer IBM MQ System Administration Guide.

• TXSeries CICS support
  IBM MQ on AIX supports TXSeries CICS using the XA interface. Ensure that CICS applications are linked to the threaded version of the IBM MQ libraries.
