APAR NUMBER: PJ40690 PRODUCT: z/TPF FUNCTIONAL AREA: DASD MOUNT/DISMOUNT SHIPPED IN PUT: 10 ABSTRACT: After PJ32026, unplanned module down can get hung due to infinite loop condition. PACKAGE CONTENTS: Source Segments: (C) base/rt/cpad.asm Object Only Binaries: None. Configuration Independent Binaries: (C) base/obj/cpad.o (C) base/load/CPAD.so Support Files: base/lst/cpad.lst base/lst/CPAD.map OTHER BINARIES TO BUILD: NO None. COMMENTS: Unplanned module down purges the module queue then calls dismount to dismount the module. Dismount checks the module queue and will wait for the module queue to be empty before proceeding. Unplanned module down freezes the module queue however causing an infinite loop if dismount finds an IOB on the queue. This can be found by a long running ECB that keeps issuing a DLAYC in CPAD.
SOLUTION: If unplanned module down is found to be calling dismount and the module queue is not empty, the module queue will be purged again instead of entering the DLAYC loop and waiting for an empty queue. COREQS: NO None. MIGRATION CONSIDERATIONS: NO None. BUILD COMMANDS AND INSTRUCTIONS: YES #maketpf commands for linux maketpf -f CPAD cpad.o maketpf CPAD link UPDATED INFORMATION UNITS: NO None. See your IBM representative if you need additional information.
