Operational metadata describes the events and processes that occur and the objects that are affected when you run a WebSphere® DataStage® and QualityStage job.
After you run a job, you can store and report on the following information about the job run:
When the job started and finished, and how long it took to run
How many rows were read, written, or referenced
Which tables or files were read from, written to, or referenced
Which stages and links were used
Whether the job failed or had warnings
The project the job was in
Any parameters used by the job
The invocation ID of the job
Any notes about running the job
