The Compaq Object Monitoring Facility (OMF) is used in problem identification
and prevention. OMF monitors the same devices as an SCF STATUS command:
processors, disks, files, processes, spooler components, audit trails, audit dumps,
TMF transactions, and tape mount requests. For more information, see the Object
Monitoring Facility (OMF) Manual.

The TSM EMS Event Viewer helps you perform many tasks associated with
viewing and monitoring EMS event logs ($0 and $ZLOG). It enables you to search
for and view log files in several ways and retrieve events based on start and end
time, subsystem, source, and multiple or specific events. The TSM EMS Event
Viewer is part of the TSM client/server application, which provides troubleshooting,
service, and maintenance, tools that run on a Compaq NonStop™ Himalaya S-series
server and on a PC-compatible workstation. For more information, see the TSM
Configuration Guide.
A Problem-Solving Process
Table A-1 shows a worksheet that you can use to help you through the problem-solving
process. You can use such a worksheet to:
•
Get the facts about a problem
•
Find and eliminate the cause of the problem
•
Focus on prevention
•
Make any appropriate escalation decisions
Copy this worksheet and use it to collect and analyze facts regarding the problem you
are experiencing. The results might not tell you exactly what is occurring, but they will
narrow down the number of possible causes.
