ALBPM Enterprise Standalone Clustering - HA Setup

Question

I wanted to know how would the HA setup be done for ALBPM standalone edition as it comes with a built in Tomcat?

Answer 1

We checked the ADF source (pasted below). It reads that markScopeDirty is getting skipped if ADF_SCOPE_HA_SUPPORT is not configured but when we debug our application the serialization fires after every pageScope/viewScope variable gets changed regardless of markScopeDirty() is being called or not. That signifies that markScopeDirty() call is not needed. Do we really need markScopeDirty() everywhere in our application or this is just a public helper method to manually trigger replication for some exceptional case? Can anyone from team Oracle explain this behavior?
@Override
public void markScopeDirty(Map<String, Object> scopeMap)
Boolean handleDirtyScopes =
(Boolean)ControllerConfig.getProperty(ControllerProperty.ADF_SCOPE_HA_SUPPORT); //checks for adf-scope-ha-support
if (handleDirtyScopes.booleanValue())
if (!(scopeMap instanceof SessionBasedScopeMap))
String msg = AdfcExceptionsArb.get(AdfcExceptionsArb.NOT_AN_ADF_SCOPE);
throw new IllegalArgumentException(msg);
((SessionBasedScopeMap)scopeMap).markDirty();
}
