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:

7.2.2.1 How to Manage Server Parameters

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:

  1. Start the REGEDT32 application using the Run... menu item in the Start menu.
  2. Select the Select Computer... menu item from the Registry menu.
  3. Enter the name of the OpenVMS server in Computer: edit box. Click on OK.
  4. Select the panel HKEY_LOCAL_MACHINE on the OpenVMS server.
  5. Expand the key you want to open by double-clicking on it.
  6. Display the data associated with a value by double-clicking on the value.

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 
 
$ 

7.2.3.2 How to Get Online Help

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
