PowerCenter session and workflow logs are stored in a separate location from the domain, application service, and user activity logs. The PowerCenter Integration Service writes session and workflow log events to binary files on the node where the PowerCenter Integration Service runs.
The Log Manager performs the following tasks to process PowerCenter session and workflow log events:
During a session or workflow, the PowerCenter Integration Service writes binary log files on the node. It sends information about the logs to the Log Manager.
The Log Manager stores information about workflow and session logs in the domain database. The domain database stores information such as the path to the log file location, the node that contains the log, and the PowerCenter Integration Service that created the log.
When you view a session or workflow in the Log Events window of the Workflow Monitor, the Log Manager retrieves the information from the domain database. The Log Manager uses the information to determine the location of the logs.
The Log Manager dispatches a Log Agent to retrieve the log events on each node to display in the Log Events window.
