Tracing level in Informatica PowerCenter

In Informatica PowerCenter, the tracing level refers to the level of detail recorded in the session log during the execution of a workflow or session. It helps in troubleshooting and debugging the workflow by providing detailed information about each step of the workflow's execution.

The tracing level can be set at different levels of granularity, ranging from minimal information to very detailed information. The available tracing levels typically include:

1. Terse: This level provides minimal information in the session log. It only records essential information such as the start and end times of tasks and the final status of the session.
2. Normal: This level provides moderate detail in the session log. It includes information about the progress of the session, such as the start and end times of tasks, row counts, and transformation errors.
3. Verbose Data: This level provides detailed information in the session log, including the data passing through each transformation. It records every row that passes through the mapping, making it useful for debugging data transformation issues.
4. Verbose Initialization: This level provides detailed information about the initialization process of the session, such as parameter values, mapping initialization, and connection details.
5. Verbose: This level provides the highest level of detail in the session log. It includes all the information from the previous levels, as well as additional debug information such as memory usage, buffer allocations, and SQL queries.

The tracing level can be configured at the session level in the Workflow Manager or Workflow Monitor interface when creating or editing a session. It allows developers and administrators to adjust the level of detail recorded in the session log based on the specific debugging requirements of the workflow.
