If you need to report an error to an IBM representative, you may be asked to switch on tracing so that information can be written to a file that can be used for locating the error.
As system performance is affected when tracing is switched on, only use the trace facility when directed by an IBM Support Center representative, or by your technical support representative.
To turn tracing on, use the DB2 facility:
db2trc on
See the DB2 UDB Command Reference documentation for further information.
To receive information specific to Net Search Extender, a mask with component in 96 can be used:
db2trc on -m *.*.96.*.*
In the case of severe errors, it may also help to look in db2diag.log.
