Catalog Files

Each SMF process uses its own catalog, which is a group of files enabled by TMF

containing persistent configuration and status information needed for process start up

and execution. When you start a process for the first time, three catalog files are set

up, the $ZSMS catalog, the storage pool process catalog, and the virtual disk process

catalog.

$ZSMS Catalog

Five files make up the $ZSMS catalog:

DISKTHRESHOLD DISKTHRESHOLD Specifies a threshold at which the disk

processes associated with physical

volumes in the storage pool should emit

an EMS disk full event.

DISKINTERVAL DISKINTERVAL Specifies a percent interval at which disk

full events should be generated after the

DISKTHRESHOLD value has been

reached.

EXTENTTHRESHOLD EXTENTTHRESHOLD Specifies a threshold at which the disk

processes associated with physical

volumes in the storage pool should emit

an EMS file full event.

EXTENTINTERVAL EXTENTINTERVAL Specifies an extent interval at which file

full events should be generated after the

EXTENTTHRESHOLD value has been

reached.

Virtual disk process attribute set:

STARTDOWN STARTSTATE Specifies if the execution state of the

virtual disk process should be set to UP

or DOWN when the process is started.

This is useful if you are trying to

diagnose a problem and do not want

processes to start automatically, or if you

have a large SMF configuration and want

to bring up parts of it separately.

CACHESIZE CACHESIZE Specifies the number of file mappings in

the SMF name cache. In some cases,

this can be used to improve file open

performance. See VDP and File System

Caches on page 2-4.

IDENTITY Contains the name of the process that created the catalog.
