4 System Management Features This chapter provides information about new features, changes, and enhancements for system managers. 4.1 OpenVMS Support for New AlphaServer GS Series Systems OpenVMS Alpha Version 7.3 provides support for Compaq’s AlphaServer GS80, GS160 and GS320 systems, which was introduced in OpenVMS Version 7.
System Management Features 4.1 OpenVMS Support for New AlphaServer GS Series Systems 4.1.3 OpenVMS Support for CPU Online Replace With OpenVMS Alpha Version 7.3, you can replace secondary CPUs on a running system without rebooting, which provides increased system maintainability and serviceability. This feature is supported only on AlphaServer GS160/320 systems. Note that replacing the primary CPU requires rebooting. To use this feature, you must first download console firmware Version 5.
System Management Features 4.3 Class Scheduler for CPU Scheduling To invoke the class scheduler, you use the SYSMAN interface. SYSMAN allows you to create, delete, modify, suspend, resume, and display scheduling classes. Table 4–1 shows the SYSMAN command, CLASS_SCHEDULE, and its sub-commands.
System Management Features 4.4 Dedicated CPU Lock Manager (Alpha) 4.4 Dedicated CPU Lock Manager (Alpha) The Dedicated CPU Lock Manager is a new feature that improves performance on large SMP systems that have heavy lock manager activity. The feature dedicates a CPU to performing lock manager operations. A dedicated CPU has the following advantages for overall system performance as follows: • Reduces the amount of MP_SYNCH time • Provides good CPU cache utilization 4.4.
System Management Features 4.4 Dedicated CPU Lock Manager (Alpha) In addition, if the number of active CPUs should ever be reduced below the required threshold by either a STOP/CPU command or by CPU reassignment in a Galaxy configuration, the Dedicated CPU Lock Manager automatically turns off within one second, and the LCKMGR_SERVER process goes into a hibernate state. If the CPU is restarted, the LCKMGR_SERVER process again resumes operations. 4.4.
System Management Features 4.4 Dedicated CPU Lock Manager (Alpha) • You can eliminate the first available nonprimary CPU as an available Fast Path CPU. To do so, clear the bit associated with the CPU ID from the IO_ PREFER_CPUS system parameter. For example, let’s say your system has eight CPUs with CPU IDs from zero to seven and four SCSI adapters that will use Fast Path. Clearing bit 1 from IO_PREFER_CPUs would result in the four SCSI devices being bound to CPUs 2, 3, 4, and 5.
System Management Features 4.
System Management Features 4.8 MONITOR Utility New Features These enhancements are discussed in more detail in the MONITOR section of the OpenVMS System Management Utilities Reference Manual and in the appendix that discusses MONITOR record formats in that manual. Also in the MONITOR utility, the display screens of MONITOR CLUSTER, PROCESSES/TOPCPU, and SYSTEM now have new and higher scale values. Refer to the OpenVMS System Management Utilities Reference Manual: M–Z for more information. 4.
System Management Features 4.9 OpenVMS Cluster Systems 4.9.2 Fast Path for SCSI and Fibre Channel (Alpha) Fast Path for SCSI and Fibre Channel (FC) is a new feature with OpenVMS Version 7.3. This feature improves the performance of Symmetric MultiProcessing (SMP) machines that use certain SCSI ports, or FC. In previous versions of OpenVMS, SCSI and FC I/O completion was processed solely by the primary CPU.
System Management Features 4.9 OpenVMS Cluster Systems Configurations that use Fibre Channel fabrics can be extremely large. Distances up to 100 kilometers are supported in a multisite OpenVMS Cluster system. OpenVMS supports the Fibre Channel SAN configurations described in the Compaq StorageWorks Heterogeneous Open SAN Design Reference Guide, available at the following Compaq web site: http://www.compaq.
System Management Features 4.9 OpenVMS Cluster Systems 4.9.5.1 SCA Control Program The SCA Control Program (SCACP) utility is designed to monitor and manage cluster communications. (SCA is the abbreviation of Systems Communications Architecture, which defines the communications mechanisms that enable nodes in an OpenVMS Cluster system to communicate.) In OpenVMS Version 7.3, you can use SCACP to manage SCA use of LAN paths.
System Management Features 4.9 OpenVMS Cluster Systems Migration support is a superset of the Rolling Upgrade support provided in earlier releases of OpenVMS and is available for mixes that are not warranted. Migration support means that Compaq has qualified the versions for use together in configurations that are migrating in a staged fashion to a newer version of OpenVMS VAX or of OpenVMS Alpha. Problem reports submitted against these configurations will be answered by Compaq.
System Management Features 4.10 OpenVMS SMP Performance Improvements (Alpha) must be placed into a mutex wait state or when mutex waiters must wake up, SCHED will still need to be acquired. • Improved Process Scheduling Changes made to the OpenVMS process scheduler reduce contention on the SCHED spinlock. Prior to OpenVMS Version 7.3, when a process became computable, the scheduler released all IDLE CPUs to attempt to execute the process. On NUMA systems, all idle CPUs in the RAD were released.
System Management Features 4.10 OpenVMS SMP Performance Improvements (Alpha) Prior to OpenVMS Version 7.3, the mailbox driver FDT routines called a routine that locked the MAILBOX spinlock and delivered any required attention ASTs. In most cases, this routine did not require any attention ASTs to be delivered. Because the OpenVMS code that makes these calls already has the MAILBOX spinlock locked, the spinlock acquisition was also an unneeded second acquire of the spinlock. As of OpenVMS Version 7.
System Management Features 4.12 New System Parameters 4.12 New System Parameters This section contains definitions of system parameters that are new in OpenVMS Version 7.3. 4.12.1 AUTO_DLIGHT_SAV AUTO_DLIGHT_SAV is set to either 1 or 0. The default is 0. If AUTO_DLIGHT_SAV is set to 1, OpenVMS automatically makes the change to and from daylight saving time. 4.12.2 FAST_PATH_PORTS FAST_PATH_PORTS is a static parameter that deactivates Fast Path for specific drivers. FAST_PATH_PORTS is a 32-bit mask.
System Management Features 4.12 New System Parameters 4.12.5 LCKMGR_MODE (Alpha) The LCKMGR_MODE parameter controls usage of the Dedicated CPU Lock Manager. Setting LCKMGR_MODE to a number greater than zero (0) indicates the number of CPUs that must be active before the Dedicated CPU Lock Manager is turned on. The Dedicated CPU Lock Manager performs all locking operations on a single dedicated CPU. This can improve system performance on large SMP systems with high MP_Synch associated with the lock manager.
System Management Features 4.12 New System Parameters In this case, the OpenVMS system allocates a total of approximately 6,291,456 bytes of nonpaged pool. Of this amount, the system divides 2,097,152 bytes among the RADs that are not the base RAD. The system then assigns the remaining 4,194,304 bytes to the base RAD.1 4.12.8 RAD_SUPPORT (Alpha) RAD_SUPPORT enables RAD-aware code to be executed on systems that support Resource Affinity Domains (RADs); for example, AlphaServer GS160 systems.
System Management Features 4.12 New System Parameters By default VCC_READAHEAD is 1, which means that the Extended File Cache can use read-ahead caching. The Extended File Cache detects when a file is being read sequentially in equal-sized I/Os, and fetches data ahead of the current read, so that the next read instruction can be satisfied from cache. To stop the Extended File Cache from using read-ahead caching, set VCC_READAHEAD to 0.
System Management Features 4.12 New System Parameters WBM_MSG_LOWER is the lower threshold for the number of messages sent during the test interval that initiates single-message mode. In single-message mode, the writes issued by each remote node are, by default, sent one by one in individual SCS messages to the node with the master write bitmap. If the writes sent by a remote node reach an upper threshold of messages during a specified interval, single-message mode switches to buffered-message mode.
System Management Features 4.13 Volume Shadowing for OpenVMS 4.13.1 Minicopy in Compaq Volume Shadowing for OpenVMS (Alpha) The new minicopy feature of Compaq Volume Shadowing for OpenVMS and its enabling technology, write bitmap, are fully implemented on OpenVMS Alpha systems. OpenVMS VAX nodes can write to shadow sets that use this feature but they can neither create master write bitmaps nor manage them with DCL commands. The minicopy operation is a streamlined copy operation.
System Management Features 4.13 Volume Shadowing for OpenVMS For more information about this new feature, including additional memory requirements for this version of Compaq Volume Shadowing for OpenVMS, refer to Volume Shadowing for OpenVMS. 4.13.2 New Volume Shadowing Features for Multiple-Site OpenVMS Cluster Systems OpenVMS Version 7.3 introduces new command qualifiers for the DCL commands DISMOUNT and SET for use with Volume Shadowing for OpenVMS.
System Management Features 4.13 Volume Shadowing for OpenVMS The device specified must be a member of a shadow set that is mounted on the node where the command is issued. • /MVTIMEOUT=yyyyyy DSAnnnn: Specifies the mount verification timeout value to be used for this shadow set, specified by its virtual unit name, DSAnnnn. The value supplied by this qualifier overrides the SYSGEN parameter MVTIMEOUT for this specific shadow set. The valid range for yyyyyy is 1 to 16,777,215 seconds.
System Management Features 4.13 Volume Shadowing for OpenVMS This qualifier indicates to the shadowing driver the site location of the shadow set member or of the shadow set (represented by its virtual unit name). Prior to using this qualifier, you can define the site location in the SYLOGICALS.COM command procedure to simplify its use. The valid range for nnn is 1 through 255.
System Management Features 4.13 Volume Shadowing for OpenVMS 4.13.2.1 How to Use the New DISMOUNT and SET Command Qualifiers The diagram in this section depicts a typical multiple-site cluster using Fibre Channel. It is used to illustrate the steps which must be taken to manually recover one site when the site-to-site storage interconnect fails. Note that with current Fibre Channel support, neither site can use the MSCP server to regain a path to the DGA devices.
System Management Features 4.13 Volume Shadowing for OpenVMS On Site A: $ DISMOUNT /FORCE_REMOVAL= $1$DGA2000: Once the command has completed, the shadow set will be available for use only at site A. On Site B: $ SET DEVICE /ABORT_VIRTUAL_UNIT DSA42: Once the command completes, the shadow set status will be MntVerifyTimeout. Next, issue the following command to free up the shadow set: $ DISMOUNT/ABORT DSA42: These steps must be taken for all affected multiple-site shadow sets. 4.13.
5 Programming Features This chapter describes new features relating to application and system programming on this version of the Compaq OpenVMS operating system. 5.1 3D Graphics Support The PowerStorm 300 (PBXGD-AD) and PowerStorm 350 (PBXGD-AE) graphics cards are now supported on Alpha-based systems.

Programming Features 5.2 3X-DAPBA-FA and 3X-DAPCA-FA ATM LAN Adapters (Alpha) 5.2 3X-DAPBA-FA and 3X-DAPCA-FA ATM LAN Adapters (Alpha) The 3X-DAPBA-FA (HE155) and 3X-DAPCA-FA (HE622) are PCI based ATM LAN adapters for Alpha based systems that provide high performance PCI-toATM capability. The 3X-DAPBA-FA adapter offers a 155 Mbps fiber connection; the 3X-DAPCA-FA adapter offers a 622 Mbps fiber connection. The datalink drivers for these adapters function in a new OpenVMS ATM environment.
Programming Features 5.4 Compaq C Run-Time Library Enhancements With OpenVMS Version 7.3, XPG5-compliant strptime becomes a default strptime function in the Compaq C RTL. However, the previous nonpivoting XPG4-compliant strptime function is retained for compatibility. The pivoting is controlled by the DECC$XPG4_STRPTIME logical name. To use the nonpivoting version of strptime, either: • Define DECC$XPG4_STRPTIME to any value before invoking the application.
Programming Features 5.4 Compaq C Run-Time Library Enhancements All C RTL functions that accept or report full file specifications will process file specifications up to 4095 bytes long, subject to the rules defined for the media format. For file specifications in OpenVMS format, there are no special restrictions. In situations where a full file specification cannot be reported because the buffer is too short, the function attempts to report the abbreviated name.
Programming Features 5.4 Compaq C Run-Time Library Enhancements 5.4.6 Alternate Way of Translating UNIX File Specifications The Compaq C RTL was enhanced to allow interpreting the leading part of a UNIX-style file specification as either a subdirectory name or a device name. The default translation of a "foo/bar" UNIX-style name to a "foo:bar" VMS-style name remains the default. To translate a "foo/bar" UNIX-style name to a "[.

Programming Features 5.7 Multipath System Services • SET DEVICE device-name/PATH=path-description-string/[NO]ENABLE • SHOW DEVICE/MULTIPATH device-name In OpenVMS Version 7.3, the capability to return path information and allow you to enable, disable, and switch specific I/O paths to any device is now implemented in the following new system services: • SYS$DEVICE_PATH_SCAN This service returns path information for a given Multipath I/O device.
Programming Features 5.9 Performance Application Programming Interface (API) 5.9 Performance Application Programming Interface (API) The Performance Application Programming Interface (API) provides a documented functional interface—the $GETRMI system service—that allows performance software engineers to access a predefined list of performance data items. For more information about $GETRMI, refer to the OpenVMS System Services Manual. 5.
Programming Features 5.11 New Process Dump Tools (Alpha) 5.11.1 DCL ANALYZE/PROCESS_DUMP Command The DCL ANALYZE/PROCESS_DUMP command invokes the OpenVMS debugger to analyze a process dump, giving you access to debugger commands for your analysis. In OpenVMS Version 7.3, most of the old DCL ANALYZE/PROCESS_ DUMP qualifiers have no effect. Only the /FULL and /IMAGE qualifiers are still valid. Both these qualifiers are still optional.
Programming Features 5.11 New Process Dump Tools (Alpha) 5.11.4 Analyzing Process Dumps on Different Systems You can analyze a process dump file on a system different from the one on which it was generated. However, if there is a base image link date/time mismatch between the generating system and analyzing system, you must copy SYS$BASE_ IMAGE.EXE from the generating system and point to it with the SDA$READ_ DIR logical name. For example: $ COPY other_node::SYS$LOADABLE_IMAGES:SYS$BASE_IMAGE.
Programming Features 5.11 New Process Dump Tools (Alpha) 5.11.6.1 Special Rights Identifiers You can use the new rights identifier IMGDMP$READALL to allow a nonprivileged user to read a complete process dump. You can use the new rights identifier IMGDMP$PROTECT to protect a complete process dump from being read by the user that created the process dump. These rights identifiers are created during the installation of OpenVMS Version 7.3 by the image SYS$SYSTEM:IMGDMP_RIGHTS.
Programming Features 5.11 New Process Dump Tools (Alpha) 2. Create a protected directory with rights identifier IMGDMP$PROTECT. For example: $ CREATE /DIRECTORY DKA300:[PROCDUMPS] /PROTECTION=(S:RWE,O:RWE,G,W) /OWNER_UIC=IMGDMP$PROTECT $ SET SECURITY DKA300:[000000]PROCDUMPS.DIR /ACL=((DEFAULT_PROTECTION,SYSTEM:RWED,OWNER:RWED,GROUP:,WORLD:), (IDENTIFIER=IMGDMP$PROTECT,ACCESS=READ+WRITE), (IDENTIFIER=IMGDMP$PROTECT,OPTIONS=DEFAULT, ACCESS=READ+WRITE+EXECUTE+DELETE+CONTROL), (CREATOR,ACCESS=NONE)) 3.
Programming Features 5.12 RMS Locking Enhancements • Caches the read-mode lock as a system lock, which is retained over accesses and only lowered to null when the lock is blocking an exclusive write request. This functionality significantly reduces both local and remote lock request traffic (the number of $ENQ and $DEQ system service calls) as well as associated IPL-8 spinlock activity and System Communications Services (SCS) messages for a cluster.
Programming Features 5.12 RMS Locking Enhancements an RMS$_RLK status. Otherwise, the record is returned with one of the following statuses: • RMS$_SUC — No other writers • RMS$_OK_RLK — Record can be read but not written • RMS$_OK_RRL — Exclusive lock is held (lock request denied) but the readregardless (RAB$V_RRL) option is set When only the RAB$V_NLK option is specified, record access can be denied.
Programming Features 5.12 RMS Locking Enhancements Table 5–2 (Cont.) Methods Available for Specifying No Query Record Locking To... Use This Method... Enable no query record locking on a per-record read operation. Set the RAB$V_NQL option in the RAB$W_ROP_2 field. Enable no query record locking at the file level.
Programming Features 5.12 RMS Locking Enhancements With this release, you can optionally request that RMS set these flags in record lock requests by setting the corresponding options RAB$V_NODLCKWT and RAB$V_NODLCKBLK in the new RAB$W_ROP_2 field. For more information about using these options, refer to the flag information in the $ENQ section of the OpenVMS System Services Reference Manual: A–GETUAI. 5.13 OpenVMS Registry Beginning in OpenVMS Version 7.
