Parameters for Buffer Synchronization

Default value: true

Value range: Boolean

For performance reasons, the SAP system buffers special data on the database in the main memory of the respective application server. If this data is changed on the database, this must be communicated to the application servers. This also applies for changes that are made by the transport tools tp and R3trans. However, for special requirements, you can switch off the synchronization mechanism.

Normally, the synchronization mechanism is used for the data changed on the database. tp resets all the buffers of the SAP system for some steps during a tp put call so that all the application servers can react to changes in the database. Buffer synchronization takes several seconds until all the application servers have read the request to reset all buffers. You can set the repetition period for reading the synchronization requests with parameters in the SAP system (rdisp/bufreftime). You can therefore set the parameters for the time tp waits until it can assume that all the buffers have been reset. See the description of the parameter bufreftime.

Default value: 180

Value range: Numeric

The value of this parameter specifies how long tp waits in seconds until it can assume that all the buffers of the SAP system have been synchronized. The value of this parameter must correspond to the rdisp/bufreftime profile parameter of the relevant SAP system.
