Generating the compression reports
You can generate the VSAM Compression and Expansion Statistics report (VSAM component) and the Non-VSAM Compression and Media Usage report (non-VSAM component).
These reports provide formatted information extracted from the REGISET by the Extract utility.
To generate Compression reports
- Use the JCL in member DACVRPT1 (VSAM Compression and Expansion Statistics report) or DACORPT1 (Non-VSAM Compression and Media Usage report) of either the HLQ.DCPSAMP or HLQ.BMCSAMP data set on the distribution tape.This JCL sorts the output from the Extract utility and produces a report.
- Modify the JOB statement, as necessary.
- Modify the PARM parameter of the BCSUEXTR statement to reflect the subsystem ID of the BCSS you are using.This step executes BCSUEXTR to retrieve information from the REGISET.
- Modify the program name of the SORT statement if you use a name other than SORT for your sort routine.This step sorts the data obtained by BCSUEXTR.
Modify the STEPLIB DD statements to reflect the names of the BMC Consolidated Subsystem (BCSS) and DATA ACCELERATOR Compression load libraries at your site.This step produces the detailed statistical report from the sorted data. You can produce a summary report, rather than a detailed report, by adding the following parameter to the DACVRPT1 EXEC statement or the DACORPT1 EXEC statement:
,PARM=SUMMARYSubmit the job.The job generates a VSAM Compression and Expansion Statistics report and non-VSAM Compression and Media Usage report. These contain statistics for all entries in the REGISET that were extracted by the Extract utility and group statistics for the prefixes of all the entries extracted by the Extract utility.
