When you select trace-to-disk reporting (see Configuring the Trace Utility), at least one trace file is used per day. You can specify the maximum size of this file. When the maximum size is reached, another file is created for that day. You can also specify the maximum number of trace files created for a day. If the maximum number is reached and another trace file is required, the oldest file for that day will be overwritten. If you specified the createBackup option, the overwritten file is saved with a filename extension of "bak."
You can specify the path and name of the trace file in the trace section of the toolkit configuration file, the dse.ini file. Two parameters are available for sequential file naming: %date and %order. The %date parameter will be replaced by the date of the trace call in the form mm.dd.yyyy, and the %order parameter will be replaced by the two-digit ordinal number of the trace file for that day, starting at "00". (The value of the %order parameter will be reset to "00" if it exceeds the specified maximum number of files per day.) For example, if the filename setting is specified as c:\dse\logs\dse-%date-%order.log, then the second trace file created for January 17, 2003 would be named c:\dse\logs\dse-01.17.2003-01.log.
