Identity Manager Database Maintenance best practices: ReIndexing

해결 방안
#1 For tables that are less than 1GB, or have less than 1 million records, there is a built-in scheduled task called "Rebuild table index".
The job runs nightly, if needed reconfigure its running schedule to run more often.
#2 For larger tables (more than 1GB, or have more than 1 million records), there is no built-in task.
As per the official documentation:
"Reindexing of tables does not take place anymore if they are larger than 1 GB or have more than 1 million data records. Maintenance of these tables must be performed by the database administrator within maintenance periods."

This falls into the general system maintenance and should be discussed with a Database Administrator.
Additionally, here are some resources which can help on how to run these reindexing maintenance tasks:
