Upgrading to Version 18.0 › Changes in CV Startup

Changes in CV Startup

l CVs and DC/UCF systems now share a common CA-delivered startup module: RHDCOMVS in z/OS.

Installation assigns the aliases IDMSDC and IDMSCV to the startup module named RHDCOMVS. You can refer to the startup module in your EXEC statement using either alias (IDMSDC or IDMSCV) or the standard name (RHDCOMVS). However, to attach a CV in z/OS, you must use the name IDMSCV to invoke it.

You no longer link your own startup modules to specify parameters or include user exits. The following startup changes have been made for 18.0:

• In 18.0, all startup parameters are specified through the PARM field on the EXEC statement. The #DCPARM macro and sample RHDCPARM program source are no longer distributed.
• User exits identified by name, such as WTOEXIT, are either enabled using the PARM field in your startup JCL or are linked with IDMSUXIT. They are no longer linked with the DC/UCF startup module.
