Activating the Database Trace
Use
Use this command only when told to do so by support. The database trace is not required for normal database operation.
You activate the database trace with this command. In this way, selected database kernel activities are logged.
The database trace is stored in the binary file
knltrace in the run directory of the database instance. To evaluate the file, you first create the text version of the database trace (
Creating the Text Version of the Database Trace).
The
<file_id> (see also:Opening a Database File) for opening this binary version is KNLTRC.
You specify which activities are to be logged using the option
<activity_list> or ALL. Separate multiple activities by spaces.The special option
ALL activates the logging of all activities.Prerequisites
You have the DBM operator authorization
DBInfoRead or DBFileRead.
