This parameter enables you to modify the ddname that CA OPS/MVS uses to locate the source REXX program when using OPS/REXX command processors. These command processors include the OPS/REXX compile command processors (OICOMP and OXCOMP) as well as other OPS/REXX command processors (OI, OPSIMEX, OX, OPSEXEC, and their aliases).
If you set the value of the REXXDDNAME parameter to a null value or a blank string, CA OPS/MVS treats it as though you set it to the default value of SYSEXEC. If you set the value to an invalid ddname, all attempts to use the OPS/REXX command processors fail.
The value of the REXXDDNAME parameter is effective even when
CA OPS/MVS is down, as long as CA OPS/MVS has been started at least once since the last system IPL, and the parameter value was set. If CA OPS/MVS has never been started, the default value of SYSEXEC is always used.
If you are using subsystems other than OPSS, always use the keyword format of the OPS/REXX command processors, using SUBSYS(OPSx), to reference the correct REXXDDNAME parameter value for that subsystem or allocate the OPS$OPSx ddname.
For more information about running multiple copies of CA OPS/MVS, see the Administration Guide.
SYSEXEC
Any 1- to 8-character string that is a valid ddname
Anytime; however, we strongly recommend that you modify this parameter only during product initialization, and that you do not change it thereafter.
Example: REXXDDNAME
This function defines SYSOEXEC as the ddname CA OPS/MVS uses to locate the source REXX program.
