CMS Batch Facility

There is a CA ACF2 for z/VM interface for the CMS Batch system component that provides logonid and password inheritance for jobs submitted to the CMS Batch. To submit a job to the CMS Batch under your own logonid, you do not need to perform any additional steps (such as inserting a password in your job).

The interface also lets you submit a CMS batch job on behalf of another user. We provide an exec, called SUBATCH, that prompts you for an CA ACF2 for z/VM password. SUBATCH automatically inserts a password into the job stream before it submits it.

CMS Batch requires you to supply link passwords in the CMS Batch job whenever a CP link command is executed. With the CA ACF2 for z/VM interface, even if link password check is ignored, you must still supply a dummy password in the CMS Batch job.

Required BATEXIT2 Exit

You must use the BATEXIT2 exit we provide with CA ACF2 for z/VM to implement the CMS Batch interface.

Installing the CMS Batch Interface

Use the following procedure to install the CMS Batch interface:

• Give each CMS batch machine the VMD4TARG logonid privilege. We recommend you also assign the AUTOONLY privilege to the CMS batch machine to prevent its use on a terminal device. Do not assign the CMS batch machine additional CA ACF2 for z/VM privileges. The only privileges you should grant to this machine are VMD4TARG, the system VMCHK value, and AUTOONLY.
• Assemble the supplied CA ACF2 for z/VM version of BATEXIT2 and place it on the S‑disk. If you use this exit for local purposes, be sure to compare the supplied CA ACF2 for z/VM version to yours, make any necessary adjustments, and then merge the two versions.
• Copy the supplied CA ACF2 for z/VM SUBATCH EXEC to a commonly accessible disk, such as the Y‑disk.
• Copy the supplied CA ACF2 for z/VM SUBTPRF XEDIT to the same disk.
• Copy the supplied CA ACF2 for z/VM SUBTPRF2 XEDIT to the same disk
• Copy the supplied CA ACF2 for z/VM BATPROF EXEC to the same disk that contains the supplied CA ACF2 for z/VM version of BATEXIT2 (usually the S disk). Review BATPROF EXEC and modify it to reflect your CMS batch virtual minidisk configuration. CA ACF2 for z/VM automatically detaches any minidisk this exec does not include at the start of each new job. This ensures subsequent jobs cannot access the minidisk of a previous job.
• Define the CMS batch machine strictly as a class G virtual machine in the VM directory.
• Installation is now complete.

Submitting Jobs on Behalf of Another User

To submit a CMS batch job on behalf of another user, use the SUBATCH EXEC to enter the password and have CA ACF2 for z/VM automatically insert it into the job stream. Or you can manually insert a job statement with the password using the following format:

/JOB machid acct# job PX password
