Configuring Tracing and Logging

You use the File Handler configuration parameters TRACE, TRACEFILEEXTEND, TRACEFILENAME, LOG and LOGFILENAME to control tracing and logging activities:

• Set TRACE=ON to turn tracing on
• Set TRACEFILEEXTEND=ON to indicate that you want trace information to be written to the end of the current trace file, if the trace file already exists
• Set TRACEFILENAME=filename if you want the trace file to have a name other than the default, which is xfhtrace.xfh
• Set LOG=ON to indicate that you want any unusual file-related situations, such as corrupted files, or automatic file recovery, to be recorded in a log file for later examination
• Set LOGFILENAME=filename if you want the log file to have a name other than the default, which is xfhlog

You can set TRACE and LOG either globally or for individual files, but you can only set TRACEFILEEXTEND, TRACEFILENAME and LOGFILENAME globally.

Here is an example configuration file:

[XFH-DEFAULT]
TRACE=OFF
TRACEFILENAME=/trace/mftracefile.xfh
TRACEFILEEXTEND=ON
LOG=ON
LOGFILENAME=/temp/mflogfile.log

[datafile1.dat]
TRACE=ON

[datafile2.dat]
LOG=OFF

In this example file tracing is set off globally and set on for the data file named datafile1.dat; new trace records are appended to the trace file, c:\trace\mftracefile.xfh, if it already exists. Logging is set on globally and set off for the data file named datafile2.dat.
