A System Management Scenario
This section provides several examples of the INFO, STATUS, and STATS commands,
showing various syntax options for these commands and the resulting display
information.
The following scenario illustrates how to use the information provided by the INFO,
STATUS, and STATS commands to detect problems within your environment and
determine how to reconfigure the system to rectify these problems.
A System Management Scenario
You know that users are encountering problems with a RUN PROGRAM command
associated with the TCP named TCP-PROBLEM. The problem occurs more often in
the morning than in the afternoon. You take these steps to investigate the problem:
1. At 9:00 a.m., you use the STATUS TCP command to check the status of
TCP-PROBLEM and its TERM objects, and find that all TERM objects are in use−
everyone is reading e-mail, for example.
This means that any other user attempting a RUN PROGRAM command
associated with TCP-PROBLEM experiences a delay (or an error) because
TCP-PROBLEM can support only a finite number of TERM objects; this number, of
course, is determined by TCP-PROBLEM’s configuration.
(Remember, a RUN PROGRAM command creates a temporary TERM object for
that device or process.)
2. You use the INFO TCP command to find that TCP-PROBLEM supports a
maximum of 25 TERM objects.
3. You use the INFO PATHWAY command to find that this PATHMON environment
can support a total of 150 TERM objects; currently, 42 TERM objects are defined
(25 of these are under control of TCP-PROBLEM).
The INFO PATHWAY command also tells you that this PATHMON environment can
support a maximum of 20 TCPs; currently, 11 TCPs are defined, one of which is
TCP-PROBLEM.
You have several options for solving this problem:
•
You can ask users to stop reading e-mail at 9:00 a.m. Of course, this solution is
probably not appropriate for an e-mail application, but it might be appropriate for
other types of applications.
•
You can increase the number of TERM objects supported by TCP-PROBLEM to
fifty. Fifty users can then issue a RUN PROGRAM command to TCP-PROBLEM.
•
You can associate the RUN PROGRAM command with another TCP (assuming
another TCP is less busy at 9:00 a.m. and can accommodate other TERM
objects). To associate the command with another TCP, copy the program
description (INFO PROGRAM, OBEYFORM), edit the description to change the
TCP, and add the description to the configuration.
