Oracle Trace Files Generated When Launching Toad or Connecting to a Database (4282748)

Each time Toad for Oracle is launched or a connection to an Oracle database is established, trace files are created on the system.

Common locations include:

• C:\temp
• C:\Users\<user_name>\Oracle\oradiag_<user>\diag\clients\user_<user>

Example trace file:

client_2912.trc

This behavior is controlled by the Oracle Client tracing configuration, not by Toad for Oracle.

If Oracle client tracing is enabled (e.g., TRACE_LEVEL_CLIENT is set to a value other than OFF), trace files will be generated automatically during client activity such as application launch or database connection.

Disable Oracle client tracing by setting the trace level to OFF.

Steps:

1. Launch Toad for Oracle.
2. Go to Session → New Connection.
3. Click the SQLNET Editor button.
4. Locate the parameter:

   TRACE_LEVEL_CLIENT
   

5. Set the value to:

   OFF
   

6. Save the changes.
7. Restart Toad for Oracle.
8. Verify that new trace files are no longer generated.
