Features of This Release

Compaq ACMS for OpenVMS, Version 4.4 includes corrections made to the product since the release of ACMS Version 4.3 and offers the following new features for ACMS and the Remote Manager.

1.1 General ACMS Features

This section describes the general features included in ACMS Version 4.4.

1.1.1 Enhanced OpenVMS and Layered Product Support

Version 4.4 provides support for ACMS with the following versions of the Compaq OpenVMS operating system and related layered products:

Compaq OpenVMS Alpha Versions 6.1, 7.1--2, 7.2--1, and 7.3
Compaq OpenVMS VAX Versions 6.1, 7.1, 7.2, and 7.3
Oracle CDD/Repository Version 7.0
Oracle Rdb Version 7.0
Oracle CODASYL DBMS Version 7.0
Compaq DECnet Phase V for OpenVMS (with Phase IV protocols)
Compaq DECforms Version 3.2 or later

1.1.2 New Flag for the ACMS$DEQUEUE_TASK Service

The ACMS$M_QUE_NORRL flag prevents the ACMS$DEQUEUE_TASK service from accessing the queue file, regardless of whether a record lock has occurred.

1.1.3 Updated ISSUBVAL.B32 Function in the ACMS$GETUAI Service

The updated ISSUBVAL.B32 function (ACC) in the ACMS$GETUAI service keeps the SYSUAF.DAT file open between calls to this service.

1.2 Remote Manager Features

This section describes the general features included in the ACMS Remote Manager Version 4.4.

1.2.1 Web-Enabled ACMS Systems Management

A new interface for Remote Manager enables ACMS users to perform most Remote Manager functions from a remote client system via one of the supported web browsers.

Known as the Remote Manager web agent, this interface is available for use with Remote Manager Version 4.4 server systems. The web agent software contains its own web server, which is installed on an OpenVMS Alpha system local to the Remote Manager server hosts used for monitoring ACMS systems. Once installed, ACMS system managers can then use the web browser from a privileged client system running TCP/IP to access the Remote Manager agent web page. From this web page, they can monitor and manage all ACMS systems as they would normally using the ACMSMGR utility.

The Remote Manager web agent is designed to be used in conjunction with the Compaq Management Agents for OpenVMS software. For information about this software and the underlying web-based enterprise management (WBEM) architecture, visit the following web site:

http://www.openvms.compaq.com/openvms/products/mgmt_agents/

For instructions on how to install, configure, and use the web interface, see Chapter 3 of the Compaq ACMS for OpenVMS Remote Systems Management Guide.

1.2.2 Enhanced System Tuning Capability

Updated ACMSMGR SET and SHOW commands (and API functions) allow system managers to better monitor and tune their ACMS systems. In addition to the standard ACMSGEN parameters, Remote Manager users can now view or set the following ACMS and OpenVMS system information:

Active, current, and stored values for the following OpenVMS system resources used by ACMS:
Channel count (CHANNELCNT)
Global sections (GBLSECTIONS)
Global page count (GBLPAGES)
Global page file (GBLPAGFIL)

The new ACMS system update rights identifier (ACMS$MGMT_SYSUPD), enables users to adjust the stored values for these system parameters per the ACC process. Using the ACMSMGR SHOW ACC command, users can also view all applicable values (current, active, and stored).
Active, stored, and current values for the following OpenVMS process resources used by ACMS:
AST queue limit (ASTLM)
Buffered I/O count limit (BIOLM)
Buffered I/O byte limit (BYTLM)
Direct I/O count limit (DIOLM)
Lock queue limit (ENQLM)
Open file limit (FILLM)
Paging file limit (PGFLQUOTA)
Timer queue limit (TQELM)
Working set default (WSDEFAULT)
Working set maximum (WSEXTENT)
Working set quota (WSQUOTA)

Users can adjust the stored values for these quotas per entity (ACC, CP, EXC, QTI, and TSC). Using the appropriate ACMSMGR SHOW command, users can also view all applicable values (current, active, and stored).
Size of the buffers used to send messages via MSS

For more information on the updated API functions, Remote Manager parameters, and ACMSMGR commands, see Chapters 6, 8, 9, and 11 of the Compaq ACMS for OpenVMS Remote Systems Management Guide.

1.2.3 ACMS Run-Time Error Collection and Filtering

Through a new class of data, ERROR, Remote Manager users can view most ACMS run-time errors normally sent to SWL or ATR logs. The Remote Manager now collects, consolidates, and stores informational messages generated by ACMS processes in an error log. This log assists ACMS system managers in troubleshooting and system monitoring by providing a single, comprehensive view of error information across multiple ACMS nodes.

The error log contains most messages generated by ACMS processes and applications at run-time and is stored in a location determined by the logical name ACMS$MGMT_ERR_LOG.

Several new ACMSMGR commands have been added that enable users to display and manage the contents of this log. SHOW ERROR lists the contents of the Error log for one or more nodes. To prevent unnecessary errors from filling the error log, users can choose to filter errors. The Error Filter table holds records that contain symbolic name, code, and ACMS node for messages to be filtered. Users create error filter records using the ADD FILTER command and display records using the SHOW FILTER command. To create a backup of the error records, users can also save filters to an ASCII text file using SAVE FILTER.

For more information on working with error logs and filters, updated Remote Manager parameters, and new ACMSMGR commands, see Chapters 5, 6, 8, 9, and 11 of the Compaq ACMS for OpenVMS Remote Systems Management Guide.

1.2.4 Data Collection Storage and Viewing

Remote Manager now allows users to save data collections at predetermined intervals for later analysis. Known as data snapshots, information storage is activated per collection record and written to a data snapshot file. Multiple collection records can share the same file, which is stored in a location determined by the logical name ACMS$MGMT_SNAPSHOT.

A new utility, ACMSSNAP, enables users to view the contents of the data snapshot file. This utility navigates through data records in the file by date and displays information using functions equivalent to ACMSMGR SHOW commands.

For more information on saving data collections, updated Remote Manager parameters, and updated ACMSMGR commands, see Chapters 5, 6, 8, 9, and 11 of the Compaq ACMS for OpenVMS Remote Systems Management Guide.
