APAR NUMBER: PJ41015 PRODUCT: z/TPF FUNCTIONAL AREA: DATA SET SUPPORT, GENERAL FILE SHIPPED IN PUT: 10 ABSTRACT: VSAM indices are not properly flushed on dismount. PACKAGE CONTENTS: Source Segments: (C) base/cp/cvf3.cpy Object Only Binaries: None. Configuration Independent Binaries: None. Support Files: None. OTHER BINARIES TO BUILD: YES (C) <sys>/obj/ccvfac.o (C) <sys>/load/CPS0.so COMMENTS: When a virtual storage access method (VSAM) dataset is dismounted all BCAs belonging to this dataset are to be removed from VFA. Routine CVF3FLVSAM loops through all BCAs and invalidates any with an index matching the input VSAM dataset. CVF3FLVSAM is invoked properly, but is not finding any matching VSAM indicies in the BCAs. When a BCA is allocated it is populated with the 8-byte FARF address from the IOB (MIOXSON) and, if possible, the same value occupies the 4-byte FARF address area in the BCA. When a BCA is allocated for GDS purposes there is no FARF address (MIOXSON is zero); the GDS index is in field MIOMCHR of the IOB. This means a VSAM record can be put into VFA, but the index saved to BCAFA is zero. When a VSAM dataset is dismounted the loop finds no matching index and so all VSAM records still reside in VFA after the dismount completes. VSAM BCAs must be populated with the VSAM dataset index rather than a FARF address of zeroes.
SOLUTION: Copy member cvf3.cpy of CSECT CCVFAC was updated, before label CVF3AL22A, to populate a VSAM BCA with information from field MIOMCHR of the IOB rather than MIOXSON. This change will allow a GDS BCA to have valid information in it so that when a VSAM dismount occurs the related BCAs will be invalidated. COREQS: NO None. MIGRATION CONSIDERATIONS: NO None. BUILD COMMANDS AND INSTRUCTIONS: YES #maketpf commands for linux maketpf -f CPS0 ccvfac.o maketpf CPS0 link UPDATED INFORMATION UNITS: NO None.
