CA JCLCheck Runtime Options › Description of Runtime Options › SPACE

SPACE

The SPACE option activates the direct-access space efficiency analysis and reporting feature.

This option has the following format:

SPace[([Rpt|NORpt] [min-percentage] [All|NOAll])]|NOSPAce

Default: NOSPace

RPT|NORPT

Controls whether CA JCLCheck lists direct-access space used by existing files or requested for new files. If you specify RPT, the DASD space usage is listed on Report 3 - Data Set Cross-Reference Report and Report 7 - Summary Data Set Cross-Reference Report

Default: NORPT

min-percentage

Specifies the minimum percentage of track utilization used in space efficiency checking. With this feature, if CA JCLCheck finds files using less than the specified minimum percentage of a track, a warning message is issued. The user specifies any value from 0 to 99. A value of 0 suppresses this efficiency check feature. Initially, we recommend a value of 75-80 percent.

Default: 0, which suppresses the feature.

ALL|NOALL

Controls whether the space efficiency check (specified by operand 2) is performed on both new and existing (ALL) data sets or only on new (NOALL) data sets created by the input job stream. Use this operand only if the minimum track efficiency percentage requested is greater than 0. The operands are positional. At least one of these operands must be specified if the SPACE option is requested.

Default: NOALL

• If this feature was specified as a system default during installation, you must code nullification of this option as NOSPA (to distinguish it from NOSP that activates the NOSPIE option).
• This option does not check the percentage of space used in a total allocation, rather, this option checks the efficiency of track utilization based on block size.

Examples: Analyze and report on space

The following example requests CA JCLCheck to report on space usage for all files and to issue a warning on any new files using less than 75 percent track capacity.

SP(RPT 75)

The following example requests that CA JCLCheck not report on data set DASD usage, except to issue a warning for any file (new or existing) using less than 75 percent track capacity.

SP(NOR 75 ALL)

The following example requests that CA JCLCheck report on space usage for all files but not perform any track efficiency analysis.

SP(RPT)
