Displaying Table Buffers (SAP Library - Monitoring in the CCMS)

Displaying Table Buffers

Procedure

From the SAP initial screen, choose Administration ® System administration ® Monitor ® Performance ® Setup/Buffers ® Buffers ® Goto ® Current local data ® Table buffers ® Single record or Generic key.

Note

You should only buffer tables that you change infrequently. You specify whether or not a table should be buffered in Transaction SE13.

Changes to buffered information must be updated in the buffers of other application servers that are sharing that information. These updates can adversely affect performance. The more servers that need updating, the more expensive the update process.

If all operations are performed on a central server, you can deactivate the buffer update messaging service.

There are two profile parameters that control the behavior of synchronization for the application server:

Parameter name	Recommended value
rdisp/bufrefmode	sendoff, exeoff (central system)
rdisp/bufrefmode	sendon, exeauto (client/server)
rdisp/bufreftime	60

Displaying Parameter Settings for the Current Instance

You define current parameters in the SAP instance profile. Restart the instance to activate any changes. To display the parameter settings:

From the SAP initial screen, choose Administration ® System administration ® Monitor ® Performance ® Setup/Buffers ® Buffers ® Goto ® Profile parameters ® Current.
