The DB2 extenders include a trace facility that records extender server activity. You should use the trace facility only under instruction of IBM service personnel.
The trace facility records information in a server file about a variety of events, such as entry to or exit from a DB2 extender component or the return of an error code by a DB2 extender component. Because it records information for many events, the trace facility should be used only when necessary, for example, when you are investigating error conditions. In addition, you should limit the number of active applications when using the trace facility. Limiting the number of active applications can make it easier to isolate the cause of a problem.
Use the DMBTRC command to control tracing. You can issue the command from a command line on an OS/2 server, AIX server, or Windows NT or later server. You must have SYSADM, SYSCTRL, or SYSMINT authority to issue the command.
