CICS XMS Subtask Startup

Use one of these methods to start the XMS subtask automatically:

• When the CICS region is started, use the DFHPLTPI definition to automatically start the XMS subtask.
• Define a transaction for the EC0CINIT program to allow for manual startup.
• Write a CICS program to transfer control (XCTL) to EC0CINIT when you want to start the XMS subtask.

Until the XMS subtask is started, expect the transactions referencing EC0XMCIC to terminate with an error message that indicates that the XMS subtask is not active

Note:

• When the CICS region is terminated, the DFHPLTSD definition is to be used to terminate the XMS subtask.

  You can manually terminate the XMS subtask through a user application program that links the EC0CIEND, or you can use the optional transaction defined for EC0CIEND for manual termination.

• If you want to terminate the XMS subtask manually, we recommend that you use the DFHPLTSD entry to terminate the XMS subtask. This definition is needed to clean up linkages to the XMS address spaces.
• To prevent users from shutting down the XMS subtask, secure the optional transaction for program EC0CIEND.
