Changing or deleting Essbase security entities, such as filters, users, groups, applications, databases, substitution variables, disk volumes, passwords, and other Essbase artifacts, can cause fragmentation in the security file (essbase.sec). Too much fragmentation in files can slow down security-related performance.
Essbase compacts the security file automatically each time the Agent is stopped. You can check the fragmentation status of the security file and you can compact the security file without stopping the Agent.
