Not sure if this still applies for latest version
But the OIF 10g (10.1.4.0.1) does have limitation when running on HA mode (using DB as the message store)
Reference : here for the test for message store
Using DB Result: 125 TPS
Using Memory Result: 240 TPS
While the R11 Ha doc says


So why not make the memory HA compliant and get rid of the excess baggage
If OAM can do it without DB, why not OIF?
