How To Fix RT047 - Buffer value for the application server

RT047 - Overview

• Message type: E = Error

• Message class: RT - Monitoring infrastructure MSG and alert texts

• Message number: 047

• Message text: Buffer value for the application server

&DEFINITION&
This MTE offers information on the quality and efficiency of critical
buffers that the SAP system uses to speed performance.
For each buffer, the alert monitor tracks the following data:
The percentage of directory entries in use. Directory entries hold the
management data for data in a buffer. Directory entry usage must never
reach 100 percent, while free space for data is still available. If all
directory entries are used, then remaining free space goes to waste, as
no new entries can be added.
Space used: The amount of space used in the area of a buffer that is
reserved for buffered data.
Hit ratio: The efficiency of the buffer (the percentage of the time that
the buffer can satisfy the information requirements of the SAP system).
After a warm-up phase while a buffer is being loaded, the hit ratio
should always be at 95% or above. Otherwise the buffer is probably too
small.
The message to the right of the MTE shows the current status of free
storage on the file system or the most critical open alert, depending
upon the view that is active in the alert monitor.
You can display detailed information on the file system by marking the
