Pagers are tasks in the user kernel thread.

Pagers write data from the data cache to the data area at each savepoint. If a large amount of data was changed so that the pagers would need to write a large number of pages at the next savepoint, they write data from the data cache to the data area before the next savepoint.

When the database starts, the pagers load the converter into the working memory.

When you remove a data volume, the pagers read the data from the volume to be removed and then write the data to the remaining data volumes.
