PJ40790: CTIN0004E - PROGRAM CHECK IN INITIALIZATION - ABORTED
Closed as program error.
See Problem Summary.
APAR NUMBER: PJ40790 PRODUCT: z/TPF FUNCTIONAL AREA: INITIALIZATION SHIPPED IN PUT: 10 ABSTRACT: Due to PJ36565, error "CTIN0004E - PROGRAM CHECK IN INITIALIZATION - ABORTED" may be received. PACKAGE CONTENTS: Source Segments: (C) base/cp/ct40.cpy Object Only Binaries: None. Configuration Independent Binaries: None. Support Files: None. OTHER BINARIES TO BUILD: YES (C) <sys>/obj/ccctin.o (C) <sys>/load/CPS0.so COMMENTS: When an IPL without clear or a ZRIPL is executed and a memory table has increased in size, it is possible that CTIN0004E Program check in initialization may be received. In this case the IPL will stop. A subsequent IPL with clear should prevent the CTIN0004E Program check in initialization error. When a memory table increases in size, less memory is available for VFA and VFA may need to be re-sized. If the machine supports enhanced Dynamic Address Translation (DAT), VFA will use enhanced DAT. As a result the size of VFA control areas and VFA buffer areas must be in 2 meg multiples. In CCCTIN ct40.cpy, the routine following label CT4VFBGET adjusts the size of the VFA control area and VFA buffer area if VFA could not be recovered on an IPL. The logic in this routine does not round the size of the VFA control and buffer areas to 2 meg boundaries. As a result, the subsequent initialization of the newly allocated VFA control area will take an error if enhanced DAT is being used.
SOLUTION: CCCTIN ct40.cpy routine to recalculate the size of the VFA control area and VFA buffer area has been updated. The size of the VFA buffer area is rounded down to the next 2 meg boundary. The size of the VFA control area is rounded up to the next 2 meg boundary. COREQS: NO None. MIGRATION CONSIDERATIONS: NO None. BUILD COMMANDS AND INSTRUCTIONS: YES #maketpf commands for linux maketpf -f CPS0 ccctin.o maketpf CPS0 link UPDATED INFORMATION UNITS: NO None.
