XA Considerations

This appendix explains how your program can use XA features.

XA Support

CA IDMS supports XA for Assembler and VS COBOL II programs. To run your application in 31-bit mode, the following conditions must be met:

Your program must be able to run above the 16-megabyte line. For more information, refer to the appropriate IBM documentation.
Your DC system must contain at least one XA program pool, XA reentrant pool, and XA storage pool.

You must link edit your program with the following options:

RMODE=ANY,AMODE=31

You must define the task, either at sysgen or by using a DCMT VARY DYNAMIC TASK command, with the LOCATION=ANY parameter.
