Management Tools

Your primary management tool is the Subsystem Control Facility (SCF) module for the

OSS Monitor, used from the Guardian environment. Reference information for that

module appears in Section 12, Open System Services Monitor.

Any Guardian-environment command that you can enter at an HP Tandem Advanced

Command Language (TACL) prompt can also be entered from the OSS environment

using the gtacl command at an OSS shell prompt. See the gtacl(1) reference

page either online or in the Open System Services Shell and Utilities Reference

Manual for additional information about that command.

You might find it convenient to manage the OSS environment from the OSS

environment. Therefore, you should know something about OSS commands and

utilities.

The Open System Services User’s Guide contains tables that show the approximate

correspondence between commands supported in the Guardian environment and the

UNIX commands and utilities supported in the OSS environment.

The OSS command set differs from other implementations of UNIX shell commands

and utilities. Many OSS commands contain HP extensions that display Guardian

environment information or allow actions that do not exist in the UNIX environment.

Figure 1-1. The Operating System Environments

Note. Before using an OSS command, read the appropriate reference page either online or in

the Open System Services Shell and Utilities Reference Manual to make sure that the

command behaves in the way you expect. OSS commands conform to the XPG4 standards,

but some OSS commands and utilities might have different options and behavior from the

version of the UNIX operating system that you are familiar with.
