ECO NUMBER: VMS722_DCL-V0200 PRODUCT: OpenVMS Alpha OPERATING SYSTEM V7.2-2 UPDATE PRODUCT: OpenVMS Alpha OPERATING SYSTEM V7.2-2 COVER LETTER 1 KIT NAME: VMS722_DCL-V0200 2 KITS SUPERSEDED BY THIS KIT: None. 3 KIT DEPENDENCIES: 3.1 The following remedial kit(s), or later, must be installed BEFORE installation of this, or any required kit: VMS722_UPDATE-V0100 3.2 In order to receive all the corrections listed in this kit, the following remedial kits, or later, should also be installed: None. 4 KIT DESCRIPTION: 4.1 Version(s) of OpenVMS to which this kit may be applied: OpenVMS Alpha V7.2-2 4.2 Files patched or replaced: o [SYSEXE]DCL.EXE (new image) 5 PROBLEMS ADDRESSED IN VMS722_DCL-V0200 KIT o On a fast SMP machine, complex pipe commands running in batch may hang. In the most common scenario, some of the subprocesses created by the pipe command are hanging in the LEF state with the parent process hanging in a HIB state. Images Affected: - [SYSEXE]DCL.EXE -- COVER LETTER -- Page 2 3 April 2003 o Exit handlers declared in user images with upcalls enabled may not run to completion. Network disconnects or Y interrupts without a CONTINUE could cause this problem. Images Affected: - [SYSEXE]DCL.EXE o Because of a change to DCL, images that get data input from command procedure lines do not return the correct exit status ($STATUS). If the image exits with a severity error having a fatal or warning status and there remain unprocessed data lines in the command procedure, the exit status is overwritten with DCL-W-SKPDAT. Below is a procedure showing the behavior change: $ SET VERIFY $ RUN TEMP !this is random test 1 !this is random test 2 !this is random test 3 !this is random test 4 this is random test 5 that DCL should just skip $ SAY "HI!" $ SET NOVERIFY Results of running command procedure before change: -------------------------------------------------- $ @temp $ RUN TEMP !this is random test 1 %NONAME-F-NOMSG, Message number 00000004 %DCL-W-SKPDAT, image data (records not beginning with "$") ignored $ Results of running command procedure after behavior change: ---------------------------------------------------------- $ @temp $ RUN TEMP !this is random test 1 %NONAME-F-NOMSG, Message number 00000004 %DCL-W-SKPDAT, image data (records not beginning with "$") ignored $ SAY "HI!" %DCL-W-IVVERB, unrecognized command verb - check validity and spelling \SAY\ $ SET NOVERIFY $ -- COVER LETTER -- Page 3 3 April 2003 Images Affected: - [SYSEXE]DCL.EXE o A file created by DCL will erroneously inherit the file extension quantity value from a previously opened file. For example: $ DIR/FULL LOGIN.COM . . . File attributes: Allocation: 18, Extend: 5000 ** Note that LOGIN.COM has DEQ set to 5000 $ OPEN/READ/SHARE FILE LOGIN.COM $ CLOSE FILE $ $ @tt/out=out.txt _$ put something in file %DCL-W-IVVERB, unrecognized command verb - check validity and spelling \PUT\ _$ Exit $ $ DIR/FULL OUT.TXT Directory $2$DKB0:[TEST] OUT.TXT;1 File ID: (8282,1,0) Size: 1/5004 Owner: [SYSTEM] Created: 21-AUG-2002 10:35:50.40 Revised: 21-AUG-2002 10:35:57.94 (1) File attributes: Allocation: 5004, Extend: 5000, Global buffer count: 0 Client attributes: None Total of 1 file, 1/5004 blocks. Images Affected: - [SYSEXE]DCL.EXE o If an upcall enabled image's execution is interrupted with ^y, and execution of a DCL command procedure is entered as the first command at the ^Y DCL prompt, an access violation occurs. For example: ^y $ @TEST %SYSTEM-F-ACCVIO, access violation, reason mask=00, virtual address=0000000000000004, PC=FFFFFFFF80B4FBEC, PS=0000001B ... -- COVER LETTER -- Page 4 3 April 2003 Images Affected: - [SYSEXE]DCL.EXE o The following call to F$GETSYI, on a system that does not support partitioning, will crash the process: $ write sys$output f$getsyi("cpu_failover") Improperly handled condition, bad stack or no handler specified. Signal arguments: Number = 0000000000000005 Name = 000000000000000C 0000000000000004 000000007FFAE000 000000007FFAE000 000000007FFAE000 0000000000000012 . . . . %DCL-S-RETURNED, control returned to process GUY %SYSTEM-F-ACCVIO, access violation, reason mask=00, virtual address=000000000000000C, PC=000000000000000C, PS=7FFAC4C3 Images Affected: - [SYSEXE]DCL.EXE 6 KIT INSTALLATION RATING: The following kit installation rating, based upon current CLD information, is provided to serve as a guide to which customers should apply this remedial kit. (Reference attached Disclaimer of Warranty and Limitation of Liability Statement) INSTALLATION RATING: INSTALL_3 : To be installed by customers experiencing the problems corrected. -- COVER LETTER -- Page 5 3 April 2003 7 INSTALLATION INSTRUCTIONS: Install this kit with the POLYCENTER Software installation utility by logging into the SYSTEM account, and typing the following at the DCL prompt: PRODUCT INSTALL VMS722_DCL /SOURCE=[location of Kit] The kit location may be a tape drive, CD, or a disk directory that contains the kit. Additional help on installing PCSI kits can be found by typing HELP PRODUCT INSTALL at the system prompt This kit requires a system reboot. Compaq strongly recommends that a reboot is performed immediately after kit installation to avoid system instability If you have other nodes in your OpenVMS cluster, they must also be rebooted in order to make use of the new image(s). If it is not possible or convenient to reboot the entire cluster at this time, a rolling re-boot may be performed. 7.1 Special Installation Instructions: 7.1.1 Scripting of Answers to Installation Questions During installation, this kit will ask and require user response to several questions. If you wish to automate the installation of this kit and avoid having to provide responses to these questions, you must create a DCL command procedure that includes the following definitions and commands: - $ DEFINE/SYS NO_ASK$BACKUP TRUE - Add the following qualifiers to the PRODUCT INSTALL command and add that command to the DCL procedure. /PROD=DEC/BASE=AXPVMS/VER=V2.0 - De-assign the logicals assigned For example, a sample command file to install the VMS722_DCL-V0200 kit would be: $ $ DEFINE/SYS NO_ASK$BACKUP TRUE $! $ PROD INSTALL VMS722_DCL/PROD=DEC/BASE=AXPVMS/VER=V2.0 $! $ DEASSIGN/SYS NO_ASK$BACKUP $ DEASSIGN/SYS NO_ASK$REBOOT -- COVER LETTER -- Page 6 3 April 2003 $! $ exit © 2002 Compaq Information Technologies Group, L.P.
