Error description
File Manager DVT when accessing Format4 DSCB for a non-conforming (eg. z/VM volume) or newly initialized VTOC was using more CPU than necessary when searching for a user specified data set.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All File Manager users displaying VTOCs. * **************************************************************** * PROBLEM DESCRIPTION: The DVT function may waste processor * * and I/O time when encountering volumes * * that do not have a valid z/OS VTOC or * * that have an empty VTOC. * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * **************************************************************** File Manager was not always performing a validity check on the extents of a VTOC, and then attempting to scan such VTOCs for entries matching the requested pattern. Empty DSCBS for non- indexed volumes were also being unnecessarily stored internally.
Problem conclusion
File Manager DVT processing has been updated in order to always check the validity of VTOC extents in order to avoid unnecessary processing and to avoid storing empty DSCBs for non-indexed volumes.
