DirMaint Overview
IBM Directory Maintenance (DirMaint) for z/VM is a CMS application that helps manage an installation's VM directory. Directory statements can be added, deleted, or altered using the DirMaint directory statement-like commands. DirMaint provides automated validation and extent allocation routines to reduce the chance of operator error. [ More ]

With z/VM V6, DirMaint is a priced, optional feature and is automatically shipped on the z/VM V6 base product media: See the announcement letter for further details, z/VM 6.4.

The priced, optional feature of the IBM Directory Maintenance Facility (DirMaint) has released a new function level (FL640) in z/VM V6.4. DirMaint FL640 includes all service applied since FL630 plus support is added for the z/VM upgrade installation procedure exit (UPGDVHXT EXEC). This exit provides the interface between the z/VM upgrade installation procedure and DirMaint so that DirMaint can be used for all of the directory updates associated with the upgrade installation. In order for this exit to work successfully, some DirMaint configuration is necessary. If you plan to use the z/VM upgrade installation procedure with DirMaint, please see Appendix C. Preparing for the z/VM Upgrade Installation Procedure here.

New support was added in DirMaint FL640 for Control Program changes. The DIRM GLOBALOPTS, MACHINE, and SETMACH commands have been updated with the new "Z" option to allow the definition of a z/Architecture-only virtual machine.

z/VM V6.4 does not support Expanded Storage (XSTORE) for either host or guest usage. The XSTORE DirMaint operand has been removed from the documentation and is supported only for compatibility. The XSTORE statement in a user directory has no function. If the directory entry for a guest includes the XSTORE statement, message HCP1401I will be issued when the guest logs on to state that XSTORE is not supported.

In DirMaint FL640, the DirMaint RACF connector support has been enhanced. New exits and configuration data specifications are added to the interface between DirMaint and RACF/VM for link and NICDEF creation and deletion, allowing for further coordination of CP and RACF privileges and discrete resource profile creation and deletion.
