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: 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. 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. Verbose Data: This level provides detailed information in the session log, including the data passing through each transformation. It...

The Lookup Transformation and Joiner Transformation are both commonly used in Informatica PowerCenter for data integration, but they serve different purposes. 1. Lookup Transformation:    - The Lookup Transformation is used to look up data from a relational table, view, or flat file. It is typically used to retrieve related data from a reference table based on a specified condition.    - Lookup transformations are useful when you need to perform a lookup operation to find matching records in a reference dataset and then use that information to enrich or filter the input data.    - Lookups can be either connected or unconnected. Connected lookups are part of the mapping flow, while unconnected lookups are called from within expressions or other transformations. 2. Joiner Transformation:    - The Joiner Transformation is used to join data from two heterogeneous sources or from the same source. It combines rows from two sources based on a con...
