Technical data

You can also use UNIX management commands to manage some components of
TCP/IP Services.
To use UNIX management commands at the DCL prompt, run the following
command procedure:
$ @SYS$MANAGER:TCPIP$DEFINE_COMMANDS
ThenenterUNIXcommandsasyouwouldonaTru64UNIXsystem.
TCP/IP management commands are described fully in the Compaq TCP/IP
Services for OpenVMS Management Command Reference manual, and in the
TCP/IP Services online help.

To exit the management control program, enter the following command:
TCPIP> EXIT
To obtain information about TCP/IP Services, enter the following command at
the DCL prompt:
$ HELP TCPIP_SERVICES
4.2 Defining Logical Names
Logical names allow you to customize component behavior. Logical names can
point to directories, database files, and log files.
To define a logical name, enter the following DCL command:
$ DEFINE
logical-name
For more information about these logical names, refer to the Compaq TCP/IP
Services for OpenVMS Management guide.
The TCPIP$CONFIG database predefines logical names for various databases.
During the menu-driven installation procedure, the software configures either the
components you select or all of the TCP/IP Services software components. These
defaults are designed to get your system up and running as an internet host with
minimal effort. TCPIP$CONFIG creates the database files.
After the initial configuration of a component, you can use logical names to modify
the settings of the component-specific parameters. Many logical names are
defined as “existence logical names”; that is, they can be either on or off. Any
value associated with them is ignored. Others require a value of text string as a
definition. Every logical name has a default setting.
For more information about how TCP/IP Services components uses logical names,
see relevant chapters in this manual and refer to the Compaq TCP/IP Services for
OpenVMS Management guide.
4.3 OpenVMS System Dump Analysis (SDA) Tool
TCP/IP Services for OpenVMS provides network-specific enhancements to the
OpenVMS System Dump Analysis (SDA) tool. For more information about SDA
enhancements, refer to DCL online help.
If your system fails, you can run the SDA tool on system reboot to analyze
the system crash dump. You can do this by adding command lines to the
SYSTARTUP_VMS.COM procedure.
