CBLVCAT Examples Menu

Searching for the 'best-fit' extent to locate a dataset or data space can be a time consuming business, but one single report is all you need with CBLVCAT.

Notes:

For MVS systems the DEV=ALL parameter will produce a VTOC report for each DASD device belonging to the esoteric group SYSALLDA.

For VSE systems the DEV=ALL parameter will produce a VTOC report for every disk drive that has a current programmer logical unit assignment.

The MERGE parameter instructs CBLVCAT to produce a single report, containing the information from all VTOCs.

The SORTD ALLOC parameters of the REPORT command request that the output be sorted in descending order of allocation size.

The SUMMARY parameter causes only freespace information to be displayed.

The STOPAFT parameter ensures that only the 100 largest freespace areas are included in the report.
