How often should we run the Cleanup Tracking file every day? or once a week?
You need to run a ETCL#DBU RELOAD every day so that the Cleanup Tracking File gets refreshed every day with new resources added to the security file.
If the resource is not on the Cleanup Tracking File, it cannot be tracked.
So by running the RELOAD every day, your Cleanup Tracking File will be in synch with the security file within 24 hours.
