Operating the OSS Environment
You operate the Open System Services environment from the Guardian environment.
As a system operator, when you are operating the OSS environment, there is little you
need to do differently from operating the Guardian environment. This section describes
what you do to operate the OSS environment that is unique to the OSS environment.
The primary sets of operating tasks are as follows:
•
Starting and Stopping the OSS Environment on page 2-1
•
Managing the OSS Subsystem on page 2-6
•
Removing the OSS File System on page 2-19
•
Monitoring OSS Processes on page 2-20
•
Managing OSS Processes on page 2-22
•
Managing OSS Interprocess Communication Facilities on page 2-34

Starting and Stopping the OSS Environment
The OSS environment was started when the system first came up. An application
program can run in the OSS environment without any additional action by using a
startup mechanism that assigns it an OSS process ID. Therefore, you actually cannot
stop the OSS environment.
However, for a program or an interactive user to start an OSS shell, use an OSS utility,
or use an OSS file, the OSS file system must be running. For most users, starting and
stopping the OSS file system is equivalent to starting and stopping the OSS
environment.
You start the OSS file system by starting the root fileset. The OSS file system runs as
long as the root fileset for your local node is started (mounted). Stopping the OSS
Monitor does not stop the OSS file system.
Possible Ways to Start the OSS File System
Starting the OSS file system is a multiple-step process:
1. The OSS Monitor must be started at least once.
2. All filesets needed by users must be started (mounted), beginning with the root
fileset.
3. All servers managed by the OSS Monitor should be started.
These steps can be performed in several ways:
•
Using the automatic startup service AUTOSTART feature described under
Automatic Startup Service on page 2-2. Configuring and using this feature properly
