Troubleshooting Guide
Use the diagnostic tools described in this chapter to gather
and process data that can help identify the cause of a problem you are having
with your OS/2 system.
Once the data is collected, it can be examined by you or by someone who is
familiar with the problem, or provided to DB2 Customer Service for analysis.
Some of the diagnostic tools available for OS/2 include:
- OS/2 logging utility
- The OS/2 logging facility provides a record of error information for
OS/2 programs. See "Using the OS/2 Logging Facility".
- FFST for OS/2 and SNA alert routing
- FFST for OS/2 allows you to capture error information at the point
of occurrence and to route SNA generic alerts either to a specified dump file
or over an SNA session to a host or to a LAN alert collection facility. See "Using the FFST for OS/2 Utility" and "Taking an SNA Trace".
- pstat
- The pstat command lists status information on which processes
are running. See "Using the pstat Command".
- SPM/2
- The System Performance Monitor for OS/2 (SPM/2) is a separately orderable
product that helps you monitor memory, memory utilization, CPU times, threads
and processes, and input/output.
- WarpCenter
- Available for Version 4 of OS/2 Warp Connect, the WarpCenter provides
access to problem determination tools, including:
- Logging and tracing tools
- Browsers to see the hardware and software configuration, and FFST settings
- A problem determination tutorial
For information, see your Version 4 OS/2 Warp documentation.
- Standalone dump utility
- The standalone dump utility records the contents of all physical memory.
This utility, which runs independently of the OS/2 program, can be used
to dump data when a problem is very difficult to reproduce, or when other
methods of problem determination cannot solve the problem. It is seldom
required by DB2 Customer Service.
- Kernel debugging for advanced problem diagnosis
- In severe situations, DB2 Customer Service can connect remotely to your
site and use kernel debugging to diagnose the cause of a problem.
