Configure the PL/I importer for a PL/I program on an IMS system

Depending on the prefix style that the target PL/I program uses on an IMS transaction system, configure the PL/I importer.

The message prefix style used by PL/I programs can either be LLZZ (4 bytes in all) or LLLL (4 bytes) followed by ZZ (2 bytes). All other IMS programs such as COBOL, C, or C++ use a two-byte LL field. For the field lengths applicable for the various IMS programs, see IMS Input Message formats and contents.

To enable IMS support, configure the PL/I importer under IBM Integration Designer and convert the LLLL (4 bytes) field into LL (2 bytes). Select the Enable IMS support option when working with the IMS TM resource adapter, but this selection is optional when working with WOLA.

When exchanging information between a WOLA external service and the target PL/I IMS program, you must specify the format for the message prefix style.

For example, if you enabled IMS support for the PL/I program, use the LLZZ prefix style. However, if you did not enable the IMS support, use the LLLL prefix style with the appropriate field length so that WOLA correctly parses the message at run time and delivers it accordingly to IMS OTMA. The IMS Transaction Manager (TM) ensures that correct LLLL size is used when delivering the message to the PL/I IMS program.

When creating the WOLA import using the New External Service wizard, you can set the values for the request and response prefix styles under the IMS OTMA connection properties area which is under Advanced.

To configure the PL/I importer, choose one of the following methods:
