A System Management Scenario
For all of these commands, you can direct the display output to a text file by including
the OUT option in your command. For example, this command directs output to the
text file named JUNE95:
= INFO /OUT JUNE95/ PATHWAY
With the INFO command, you can use the OBEYFORM option to capture a
configuration for use in future start operations. (See Capturing a Configuration on
page 5-21.)
This section provides several examples of the INFO, STATUS, and STATS
commands, showing various syntax options for these commands and the resulting
display information.
This scenario illustrates how to use the information provided by the STATUS
commands to detect problems within your environment and determine how to rectify
these problems.
A System Management Scenario
You know that users are encountering difficulties with some of their workstation client
applications. The applications will not come up. By asking a few questions, you
determine that RSC is running. Investigation on the host side reveals no
telecommunications outages, so the problems must be in the PATHMON environment.
1. You use the STATUS SERVER * command to determine which server classes are
currently running.
2. You notice that no server processes are running in the server class A-NAME-
SERVE. You know that this server class is required for all client applications.
You also know that all other server classes must be stopped before the A-NAME-
SERVE server class can be started.
3. You decide to gracefully shut down existing applications using the FREEZE
SERVER * command.
4. You use the STATUS SERVER * command to confirm that all server classes are
frozen.
The STATUS command display reveals that two server classes are still running,
presumably because they contain servers processes that are still completing long
transactions. These two server classes are named B-NAME-SERVE and C-
NAME-SERVE.
5. You use these two commands to attempt to freeze the two server classes:
= FREEZE SERVER B-NAME-SERVER !
= FREEZE SERVER C-NAME-SERVER !
6. You use a STOP SERVER * command to stop all server classes.
