Parameter
rdisp/bufrefmode
Short text
Buffer Refresh Mode
Parameter Description
For performance reasons, a large amount of data that is actually stored in database tables is held in local buffers in the ABAP server to improve access times. This is also true for data that “seldom” changes. So that the buffer content is read again after changes, a buffer synchronization is performed periodically. You can configure this synchronization as follows:
• The default setting sendon,exeauto means that the buffer synchronization is activated.
• sendon means that changes to buffered objects are logged in the table DDLOG
• exeauto means that the local buffer is updated by cyclical processing of the new DDLOG records.
• sendoff,exeoff deactivates the buffer synchronization.
