ECO NUMBER: VAXSYSA02_062 PRODUCT: OpenVMS VAX OPERATING SYSTEM 6.2 UPDATE PRODUCT: OpenVMS VAX OPERATING SYSTEM 6.2 COVER LETTER 1 KIT NAME: VAXSYSA02_062 2 KITS SUPERSEDED BY THIS KIT: VAXSYSA01_062 3 KIT DEPENDENCIES: 3.1 The following remedial kit(s) must be installed BEFORE installation of this, or any required kit: None. 3.2 In order to receive all the corrections listed in this kit, the following remedial kits should also be installed: VAXF11X04_062 For an explanation of the cause for the following dependencies, see the MME-related problem descriptions under the section titled "PROBLEMS ADDRESSED IN VAXSYSA02_062 KIT": VAXINIT01_062 VAXBACK03_062 VAXMTAA03_062 VAXDISM02_062 VAXMOUN03_062 4 KIT DESCRIPTION: 4.1 Version(s) of OpenVMS to which this kit may be applied: OpenVMS VAX V6.2 4.2 Files patched or replaced: o [SYS$LDR]ERRORLOG.EXE (new image) o [SYS$LDR]EXCEPTION.EXE (new image) o [SYS$LDR]EXEC_INIT.EXE (new image) -- COVER LETTER -- Page 2 17 November 1998 o [SYS$LDR]IMAGE_MANAGEMENT.EXE (new image) o [SYS$LDR]IO_ROUTINES.EXE (new image) o [SYS$LDR]LOCKING.EXE (new image) o [SYS$LDR]MESSAGE_ROUTINES.EXE (new image) o [SYS$LDR]PAGE_MANAGEMENT.EXE (new image) o [SYS$LDR]PROCESS_MANAGEMENT.EXE (new image) o [SYS$LDR]SYSLDR_DYN.EXE (new image) o [SYS$LDR]SYSTEM_PRIMITIVES.EXE (new image) o [SYS$LDR]SYSTEM_PRIMITIVES_MIN.EXE (new image) o [SYS$LDR]VBSS.EXE (new image) o [SYS$LDR]WORKING_SET_MANAGEMENT.EXE (new image) o [SYS$LDR]EXCEPTION.STB 5 PROBLEMS ADDRESSED IN VAXSYSA02_062 KIT o If a system has been up for 497.1 days without rebooting, the system cell EXE$GL_ABSTIM_TICS (number of 10 millisecond tics since boot) will overflow. This problem can cause some processes to remain indefinitely in the RWMPB or COMO scheduling state. Furthermore, candidate processes for Virtual Balance Set Slot (VBSS) selection can be missed. Code using the EXE$GL_ABSTIM_TICS cell to time other activity could get stuck if a reference counter is large (FFFFxxxx) and the EXE$GL_ABSTIM_TICS value is low due to the overflow (0000xxxx). Most such checks compare to see if the number of tics is larger than the reference value, i.e. has the event come due? o A possible system crash occurs during Host Based RAID Unbinds with MME code enabled. A mailbox read synchronization problem causes the crash. This problem only occurs when a host-based RAID UNBIND command is done while an MME-based application is running. This problem can occur in several different code areas of the operating system. In order to eliminate all known instances of this problem, the following remedial kits (or their supersedants) will also need to be installed: -- COVER LETTER -- Page 3 17 November 1998 o VAXBACK03_062 o VAXDISM02_062 o VAXINIT01_062 o VAXMOUN03_062 o VAXMTAA03_062 o A process using MME could potentially "miss" the VOL1 label on a tape. Also, a process could "hang" trying to send a message to the MME process. o The performance counter PMS$GL_NPAGDYNEXPS (cell) was never incremented above its initial value of zero. It can be displayed by: 6 PROBLEMS ADDRESSED IN VAXSYSA01_062 KIT o Updates to application ACE get lost. Customer code locks the ACL, reads their ACE, updates a count field, re-writes the ACE, and unlocks the ACL. The change to the count gets lost. In order to get this full fix you must also install the VAXF11X04_062 remedial kit. 7 PROBLEMS ADDRESSED IN VAXSYS11_062 KIT o An application (DSM) was hanging with processes going into an RWMBX state. DEFMBXBUFQUO was increased in case DSM didn't specify the sizes of its mailboxes. Later the processes went into RWNPG. 8 PROBLEMS ADDRESSED IN VAXSYS10_062 KIT o OpenVMS VAX systems using the SYS$SET_SECURITY or SYS$CHANGE_ACL system services to protect File Objects are inconsistent. o The image PROCESS_MANAGEMENT would not LINK properly due to an undefined symbol, SCH$GL_MAXPIX. o OpenVMS could potentially create processes in the same group UIC with the same process name. -- COVER LETTER -- Page 4 17 November 1998 On OpenVMS VAX systems, SS$_NOSLOT could be returned when there is one process entry slot left, the last one used. o SECREFNEG bugchecks can occur when running heavy loads on SMP systems. The SECREFNEG bugcheck occurs when the reference count on a section is decremented; the count ends up negative, rather than at zero. o A potential problem exists when a batch job process termination message is sent to the JOB_CONTROL process. If the Job Controller's mailbox is full at the time the message is sent, the message could be dropped and lost. The result could be that SHOW QUEUE shows "executing" jobs with no associated process on the system. o A BADPRCPGFLC bugcheck occurs if more than 2^20 pagefile pages are used and only a single pagefile is installed. 9 PROBLEMS ADDRESSED IN VAXSYS04_062 KIT o An ALLOCATE/GENERIC command erroneously returns the message "no such device available". 10 PROBLEMS ADDRESSED IN VAXSYS08_062 KIT o Crash caused by R1 corruption. 11 KIT INSTALLATION RATING: The following kit installation rating, based upon current CLD information, is provided to serve as a guide to which customers should apply this remedial kit. (Reference attached Disclaimer of Warranty and Limitation of Liability Statement) INSTALLATION RATING: INSTALL_1 : To be installed by all customers. 12 INSTALLATION INSTRUCTIONS: Install this kit with the VMSINSTAL utility by logging into the SYSTEM account, and typing the following at the DCL prompt: @SYS$UPDATE:VMSINSTAL VAXSYSA02_062 [location of the saveset] The saveset location may be a tape drive, or a disk directory that -- COVER LETTER -- Page 5 17 November 1998 contains the kit saveset. The images in this kit will not take effect until the system is rebooted. If you have other nodes in your VMS 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. Copyright (c) Compaq Computer Corporation, 1998 All Rights Reserved.
