PJ40971: INCORRECT INFORMATION ON ZDTIM STP INFO COMMAND AFTER CTNID CHANGE.
Closed as program error.
See Problem Summary.
APAR NUMBER: PJ40971 PRODUCT: z/TPF FUNCTIONAL AREA: CLOCKS SHIPPED IN PUT: 10 ABSTRACT: Due to PJ36831, command ZDTIM STP INFO may display incorrect information. PACKAGE CONTENTS: Source Segments: (C) base/cntl/tpf_app_base.cntl (C) base/rt/cqbz.asm Object Only Binaries: None. Configuration Independent Binaries: (C) base/obj/cqbz.o (C) base/load/CQBZ.so Support Files: base/lst/cqbz.lst base/lst/CQBZ.map OTHER BINARIES TO BUILD: NO None. COMMENTS: Command ZDTIM STP INFO obtains Server Time Protocol (STP) information from the system clock area memory table. CINFC R,CMMCLST points to the system clock area and macro SC0TM describes it. The STP information in the system clock area is initialized in restart. If the STP configuration changes, STP interrupt logic will refresh the system clock area in memory. However, if STP interrupts are disabled on z/TPF, changes to the STP configuration are not reflected in the system clock area in memory. On a processor that has STP enabled, z/TPF will disable STP interrupts for the LPAR when the TOD clock on that LPAR is local. When command ZATIM xxxx TOD GOOD or ZATIM xxxx TOD GOOD SSTP or ZATIM xxxx LOCAL is used, the TOD clock will be local on the LPAR where the command was input and STP interrupts will be disabled. Therefore, when one of these commands are used, the system clock area may not have current STP information and ZDTIM STP INFO may display old information.
SOLUTION: Command ZDTIM STP INFO has been updated. First, the system clock area is refreshed with the most current STP configuration information. Next, information for command ZDTIM STP INFO is obtained and displayed. COREQS: NO None. MIGRATION CONSIDERATIONS: NO None. BUILD COMMANDS AND INSTRUCTIONS: YES #maketpf commands for linux maketpf -f CQBZ cqbz.o maketpf CQBZ link UPDATED INFORMATION UNITS: NO None.
