Description

---

This table reflects the table buffer manager statistics for all of the sessions that are present on the ElevateDB server that the current session is logged in to. This information is useful in determining how efficient the ElevateDB Server is with respect to I/O, and also how much I/O is actually taking place. For example, a large number of reads for the row buffer manager for a table may indicate that you have an un-optimized query or filter present in your application that is causing an inordinate number of row reads. The current user must be granted the system-defined Administrators role in order to view this table. Please see the User Security topic for more information.

The BufferMgr column values are as follows:
