7.2 Managing Server Configuration Parameters
The Advanced Server software relies on the OpenVMS Registry to store and
reference server configuration parameters. (For information about
managing the OpenVMS Registry, refer to the OpenVMS System Manager's Manual.)
In previous versions of the server software (for example, PATHWORKS for OpenVMS servers), the LANMAN.INI file is used to store server parameters. Advanced Server stores these parameters in the OpenVMS Registry, which is similar to the Windows NT Registry. If you are upgrading a system from PATHWORKS V6 for OpenVMS (Advanced Server) to Advanced Server for OpenVMS, the parameters and settings in the existing LANMAN.INI file are migrated to registry parameters when you run the PWRK$CONFIG.COM initial configuration procedure, as described in the Advanced Server for OpenVMS Server Installation and Configuration Guide.
With Advanced Server for OpenVMS, server parameters are stored in the OpenVMS
Registry. The server parameters described in Appendix A, Server Configuration Parameters, are
available for modification.
7.2.1 OpenVMS Registry Overview
The OpenVMS Registry, like the Windows NT Registry, is a single
cluster-wide hierarchical database of configuration information about
hardware and software (including both the operating system and
applications). The OpenVMS Registry is accessible from Windows NT
applications as well as from OpenVMS utilities and Advanced Server
utilities.
7.2.1.1 Registry Architecture
Both the Windows NT and the OpenVMS Registry contain keys and values:
The OpenVMS Registry contains two predefined roots of keys:
Parameters defining the configuration of the Advanced Server are stored in the key HKEY_LOCAL_MACHINE. Each server parameter and the key under which it is defined is listed in Appendix A, Server Configuration Parameters.
Figure 7-6, Example Keys to Advanced Server Registry Parameters, shows the registry architecture on OpenVMS as displayed by the Windows NT registry editor.
Figure 7-6 Example Keys to Advanced Server Registry Parameters
The selected key, Parameters, contains the SrvComment value, which defines a text string that is broadcast to identify the Advanced Server.
For more information about the server configuration parameters and data
that may be associated with them, see Appendix A, Server Configuration Parameters.
7.2.1.2 The Registry Server
The OpenVMS Registry Server starts automatically when the Advanced Server
is started. The Registry Server must be running in order for the
Advanced Server to run. If the Registry Server is not running when you
initially configure the Advanced Server or when the Advanced Server is
started, the Advanced Server attempts to start the Registry Server. For
more information about configuring and starting the Registry Server,
refer to the OpenVMS Alpha V7.2 Upgrade and Installation Guide.
7.2.2 Registry Parameters
Server parameters are stored in the OpenVMS Registry when you configure the Advanced Server. A parameter is stored in the registry only if the data associated with the parameter is changed from the supplied default setting. A server parameter is stored in the OpenVMS Registry when:
You can manage server parameters in the OpenVMS Registry using any one of a number of utilities and tools, depending on the way you manage the Advanced Server software.
Managing the Registry from a Windows NT Computer
You can manage Advanced Server software remotely, from a Window NT computer running Windows NT Server software. Windows NT provides two registry editor utilities: REGEDT32 and REGEDIT. Use the REGEDT32 application to display and modify server parameters. For more information about using REGEDT32, refer to the Window NT product documentation. (The REGEDIT utility does not provide security and cannot be used to modify the OpenVMS Registry. Refer to the Windows NT documentation for more information.)
When you access the OpenVMS Registry from a network client, the connection is based on network user authentication. Therefore, you must be logged on to the network in order to access the registry from a network client. If you are using Windows NT REGEDT32 to modify server parameters, you must be logged on as Administrator.
To access the server parameters in the OpenVMS Registry:
Figure 7-6, Example Keys to Advanced Server Registry Parameters, provides an example of the REGEDT32 display.
Managing the Registry from OpenVMS
If you are managing the Advanced Server from the OpenVMS system (using a workstation or terminal emulator), you can use either the the OpenVMS system registry control program (REG$CP) or the PWRK$REGUTL utility supplied with the Advanced Server.
Compaq recommends that you use PWKR$REGUTL to manage server
configuration parameters, because it has built-in knowledge of keys and
values used by the Advanced Server, including the attributes of the data,
such as minimum, maximum, and default values. The following sections
describe how to manage server configuration parameters using the
PWRK$REGUTL utility.
7.2.3 Using the PWRK$REGUTL Utility
The PWKR$REGUTL utility is available for you to use after you install the Advanced Server software. The program is found at:
SYS$SYSTEM:PWRK$REGUTL.EXE |
If your process has included the Advanced Server command definitions in the PWRK$DEFINE_COMMANDS.COM file, or if you have defined the REGUTL command, you can start the PWRK$REGUTL utility by entering the REGUTL command. To define the REGUTL command and start the utility, enter the following commands at the OpenVMS command prompt:
$ REGUTL :== $SYS$SYSTEM:PWRK$REGUTL.EXE $ REGUTL REGUTL> |
The PWRK$REGUTL utility responds by displaying the REGUTL> prompt.
To use PWRK$REGUTL to access the OpenVMS Registry, your process must have one of the following:
The PWRK$REGUTL utility has a command line user interface that is compatible with OpenVMS DCL command conventions.
When you use the PWRK$REGUTL utility, the Registry Server must be
running on the OpenVMS system. However, the Advanced Server need not be
running. This allows you to modify server configuration parameters
before the Advanced Server is started.
7.2.3.1 How to Exit PWRK$REGUTL
To exit the PWRK$REGUTL utility, enter the EXIT command in response to the REGUTL> prompt. For example:
REGUTL> EXIT $ |
The PWRK$REGUTL program includes complete online help, displaying the PWRK$REGUTL commands, qualifiers, and parameters. The following sections describe some common operations performed with PWRK$REGUTL. For example, display the online help as follows:
The PWRK$REGUTL utility is provided with Advanced Server for OpenVMS
for setting and modifying server configuration parameters. Refer to
the Advanced Server for OpenVMS Server Administrator's Guide for more
information about using this utility.
You can get more help by entering any of the following commands:
CREATE KEYS DELETE KEY
DELETE KNOWN KEYS DELETE KNOWN VALUES
DELETE VALUE EXIT
HELP SET MODE
SET VALUE SHOW MODE
SHOW VALUE
Topic?
REGUTL>
|
This example shows the top-level help, listing the possible commands.
The help file displays further information about specific commands when
you enter the command name after the Topic? prompt.
