A trace file is a log of SQL run in a particular session or sesesions focused on selects, inserts, updates, and deletes. A trace file can be used in many circumstances including reviewing performance, finding tables and views referenced, or finding the root of an error.
One can enable trace through the forms by using the Help menu, choosing the daignostics menu,trace and then selecting the appropriate trace for your needs .
Most commonly if debugging an error, you should at least provide trace with binds When debugging a performance issue, you may consider using trace with binds and waits.
For example, the following is the navigation to enable trace in a form:
Goto the Oracle Applications -->Login -->Open the form where the error occurs but do not yet cause the error.
Enable SQL*Trace by choosing Help > Diagnostics > Trace > Trace with binds
A message appears indicating that the trace will be recorded
Note the file name and location of the file
Now reproduce the error.
Once the error occurs, disable trace as soon as possible.
Disable SQL*Trace by choosing Help > Diagnostics > Trace > Trace off
The same file name and location will be noted in case you need it again.
Retrieve the trace file.
A simple way to enable trace in a concurrent program is to review the concurrent program definition and select trace enabled. This will enable trace without binds for all users that run the program.
For example, the following steps could be used.
Goto Sysadmin > Concurrent > Program > Define
Query the concurrent program
Check the trace box to enable trace

How does one enable trace in the Oracle Application screens / forms?
