Tracing level in the case of informatica specifies the level of detail of information that can be recorded in the session log file while executing the workflow.

4 types of tracing levels supported

1.Normal: It specifies the initialization and status information and summerization of the success rows and target tows and the information about the skipped rows due to transformation errors.

2.Terse specifies Normal + Notification of data

3. Verbose Initialisation : In addition to the Normal tracing, specifies the location of the data cache files and index cache files that are treated and detailed transformation statistics for each and every transformation within the mapping.

4. Verbose data: Along with verbose initialisation records each and every record processed by the informatica server

For better performance of mapping execution the tracing level should be specified as TERSE
Verbose initialisation and verbose data are used for debugging purpose.

RE: What are tracing levels in transformation?
Tracing level keeps the information aboaut your mapping and transformation.
there are 4 kind of tracing level which is responsible for giving more information on basis of their characterictis.

Thanks
