Buffer monitoring?

Answer Posted / pranay

Every SAP instance has various buffers, in which data to be
accessed by users is stored. When the data is in the buffer,
the database does not have to be accessed, because buffers
enable direct reads from the main memory of the application
server.

There are two advantages to this:

1> Accesses to SAP buffers are normally 10 to 100 times
faster than accesses to the database.

2> Database load is reduced. This is increasingly important
as your system grows in size.

Monitoring SAP Table Buffering

Three problems can occur in the area of SAP table buffering
and they Problem areas should be monitored:

1> Tables are designed too small and as a result,
displacements (swaps)occur. Check that the table buffer has
at least 10% free space and at least 20% free directory entries.

2> Tables may be buffered that, for reasons of performance,
should not have been buffered, either because they are
changed (invalidated) too often or because they are too large.

3> Tables that should be buffered for reasons of performance
are not buffered. This is mainly the case for tables that
are created in the customer system, whether explicitly in
the ABAP dictionary or implicitly in customizing (for
example, condition tables).
