Command parameters
- -duration duration_num
- Specifies that trace is turned on for the specified time in seconds.

consuming EDUs. If this option is not specified the default time period
is 10 seconds.

The value of <time-stamp> has the
following format, hours_minutes_seconds.
- -fmt
- Generates a trace format report. The name of the format files
are db2trcon.<time-stamp>.fmt. The value

Examples
The following example turns the
db2trc command
on for 1 minute:
db2trcon -duration 60
To turn the
db2trc command
on for the top 10 CPU consuming EDUs for the default time period of
10 seconds and to place the trace in
tmpDump.dmp,
issue:
db2trcon -top 10 -f tmpDump.dmp
The following example turns the
db2trc command
on for 45 seconds for the top 5 processor time consuming EDUs, collected
in 15 second intervals. When the
db2trc command
is turned off,
db2trcon generates the dump, flow
and format files.
db2trcon -duration 45 -top 5 -interval 15 -fodc -ff
Usage notes
The db2trcon command
always generates a dump file if issued with the -duration parameter.
The db2trcon command also always generates a trace
dump file if it is issued without the -f parameter
from the db2trc command. The name of the dump file
is db2trcon.<time-stamp>.dmp. The value
of <time-stamp> has the following
format, hours_minutes_seconds.
