Incrementing/Decrementing the Trace Level 

Use

Use this procedure to increment/decrement the trace level for the developer trace files (dev_jcontrol, dev_<component name>) of the processes. By default, the trace level is set to 1. In some critical cases and in problem analysis, it is recommended that you increase the trace level to log more information in the developer trace files.

The value range of the trace level property can be between 0 (the lowest) and 3 (the highest).
