Summary :
The SAP Note explains the profile parameters controlling buffer synchronization. The key parameters are rdisp/bufrefmode and rdisp/bufreftime. The former dictates whether synchronization records are logged and if periodic buffer invalidation occurs. In systems with multiple instances, rdisp/bufrefmode must be set to "sendon,exeauto" for all instances to ensure data consistency. For single-instance systems, it can be set to "sendoff,exeauto," but must be adjusted when adding more instances. The rdisp/bufreftime parameter sets the interval for buffer invalidation, defaulting to 120 seconds. Kernel patches now ensure systems with multiple instances default to "sendon" mode automatically, enforcing consistent synchronization.
