Data Set Allocation Parameters

This section discusses the data set allocation parameters.

Non-SMS Parameters (ignored for SMS-controlled data sets)

If the spool files are not under SMS control, you can define either the VOLSER or UNIT parameters to control the placement of spool data sets.

In the VOLSER field, you can specify the volume serial number of the disk that will be used for the spool files. If this field is left blank, the system will select a volume based on UNIT type.

In the UNIT field, you can specify a generic device type such as 3390 or an esoteric device group name such as SYSALLDA. The default is SYSDA.

SMS Parameters

If the spool files are under SMS control, you can use these parameters to control the placement, archive, backup, etc. of the spool data sets.

In the MGMTCLAS field, you can specify the management class name to be used. This management class must be one of those that have been set up by the storage administrator at your site. It should also be a management class that excludes the spool data sets from backup and migration.

In the STORCLAS field, you can specify the storage class name to be used. This storage class must be one of those that have been set up by the storage administrator at your site. The storage class set by this parameter is used instead of the UNIT= and VOLUME= parameters and it determines where a data set is allocated.

Spool Control Parameters

The Spool transfer interval is the period between transfers from the spool to the KSDSJOB file. This parameter can be set in the range from 5 to 60 minutes. A short interval is recommended if currency of the job file is the prime consideration; the use of a longer interval will reduce the resources that are used by the servers.

The Refresh the Top Scope values parameter sets the frequency that the Top Scope values are recalculated during the spool transfer process. This function is a heavy resource user and the frequency should be set to reflect this fact. Once per day should be more than sufficient for most sites. The frequency can be related to time by using the calculation (interval * frequency = refresh period in minutes).
