This section 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.
