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 6.2.
The priced, optional feature of the IBM Directory Maintenance Facility
(DirMaint) has released a new function level (FL620) in z/VM
V6.2. DirMaint FL620 includes all service applied since FL540.
Support is added for z/VM Single System Image
Clusters. A z/VM single system image (SSI) cluster is a
multisystem environment in which the z/VM member systems
can be managed as a single resource pool and running virtual
servers (guests) can be relocated from one member to another.
For more information about the SSI environment and setting up SSI
clusters, see
z/VM: CP Planning and Administration.
To support SSI clusters, the following changes have been made in
DirMaint FL620:
- Many DirMaint commands have been updated to support new
IDENTITY and SUBCONFIG directory entries and the new BUILD
directory statement.
- DIRM ADD command has been updated for cloning SUBCONFIG
entries. In support of this, a new :SSI_VOLUMES. section
has been added to the EXTENT CONTROL file.
- DIRM DIRECTORY command has been updated to add, change or
delete the SSI option and additional volume labels.
- DIRM GLOBALOPTS, OPTION and SETOPTN commands have been updated to
add, delete, alter or query the new CHPIDVIRTUALIZATION option.
- New DIRM SSI command has been added to prepare a source
directory for use within an SSI cluster.
- New DIRM UNDOSSI command has been added to reverse changes
made to a source directory by the DIRM SSI command.
- New DIRM VMRELOCATE command has been added to support the new
VMRELOCATE directory statement in a user or profile entry.
- New support has been added for the satellite server machines
to act as a spool file bridge for commands to and responses from
the DIRMAINT machine for users on remote nodes to the DIRMAINT
machine in an SSI environment.
Note: To use the functions that define and maintain an SSI
cluster, the IBM z/VM Single System Image Feature must be
licensed and enabled.
