Description

The XDMSSN parameter is available only for z/OS with CRAM-XDM.

The XDMSSN parameter passes a z/OS secondary subsystem name that overrides the value stored in the CRAM IGCLM244 module. That value, a maximum of four characters, is initially specified during CRAM installation.

Example: XDMSSN=SS03

On the client side, the XDMSSN parameter applies to the following IODEV threads and can be in the form:

subsystem:channel

where subsystem is a 4-character name, separated by a colon (:) from channel, which is an 8-character name.
