How To Fix DB6101 - Buffering quality

SAP Error Message - Details

• Message type: E = Error

• Message class: DB6 - DB6: Alert Monitoring and Alert Configuration

• Message number: 101

• Message text: Buffering quality

What causes this issue?

The quality of the buffer pool is determined by the hitrate for read
accesses. This is the percentage of requested data that is already in
the buffer and does not have to be physically read from the buffer.

System Response

If the quality falls below the assigned threshold value, the access
performance suffers as a consequence of increased input/output.

How to fix this error?

You should increase the size of the pool if the buffer pool performance
is poor. Note that the increased demand for virtual memory causes more
paging if there is not enough real main memory available.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
