DBSPACE an IDMS tool for reviewing space utilization

DBSPACE

A tool for quickly determining space utilization for CA-IDMS areas.

PTF'S For DBSPACE Rel 2.0 - CA-IDMS 10.X Compatible

PTF 01 -

Scratch requests bypass IDMSDBMS and use IDMSDBIO directly. Space management pages (maintained by IDMSDBMS) are NOT used for the scratch area. Instead, CV's scratch manager uses a bitmap (in storage) of scratch pages currently allocated. No pages are reserved for space management in the scratch area. (IDMSINIT initializes some pages as SMPs, but the scratch manager doesn't treat them any differently from non-SMP pages).
When DBSPACE is run with a global DMCL and PROCESS=TOTAL, DBSPACE was attempting to process the scratch area just like any other area. If scratch data had been written on a page that IDMSINIT had initialized as an SMP, DBSPACE was interpreting the page's contents as space management entries, often finding values that are negative or larger than the scratch page size. This would cause an ERROR 040 message to be issued and cause the jobstep to issue a completion code of 8.
This PTF causes DBSPACE to ignore the scratch area. This allows PROCESS=TOTAL using the global DMCL to execute without issuing the error message.

PTF 03 -

This PTF causes DBSpace to print a ? on the map report if an invalid SME value is encountered and to continue processing as if no error had occurred. Without this PTF, DBSpace issues error message 40 and skips the remainder of the area/file.
Pages whose SMP is invalid will not be tallied for the Recap or Histogram reports, so the total pages on these reports will be less than the actual number of pages.
