Streaming Cluster Replication (SCR) was introduced as a performance enhancement to cluster replication in 8.0 but was found to cause problems in 8.0, 8.0.1, and 8.0.2. These issues were fixed in 8.0.2 FP1 and 8.5.
The DEBUG_SCR_DISABLED parameter can be used to disable SCR while continuing to provide traditional cluster replication service.
SCR was disabled as a default feature in 8.0.2 but is enabled by default in all other releases of 8.x and 8.5.x.
Set DEBUG_SCR_DISABLED=1 in the server's notes.ini for Domino releases 8.0 and 8.0.1. Enabling the parameter is not necessary for 8.0.2 because it is disabled by default. For releases 8.0.2 FP1, 8.5 and later, remove the parameter to take advantage of SCR's performance optimization.
This setting is only recommended for Domino server versions 8.0 and 8.0.1.
The Domino server must be restarted after modifying this setting.
