Understanding Serviceguard Extension for SAP
The Replicated Enqueue
Chapter 134
SAP offers two possibilities to configure Enqueue Replication Servers:
1. SAP self-controlled using High Availability polling
2. Completely High Availability failover solution controlled
SGeSAP provides a completely High Availability failover solution
controlled implementation that avoids costly polling data exchange
between SAP and the High Availability cluster software. There are
several SAP profile parameters that are related to the self-controlled
approach. Most of these parameters have names that start with the
string enque/enrep/hafunc_ . They will not have any effect in SGeSAP
clusters.
