A cluster, Cluster1, contains application servers Server1 and Server2. Cluster1 is configured as a member of service integration bus(SIBus)Bus1 using the High availability messaging engine policy.
A messaging engine (ME) for Busl starts up on Server1, then Server1 crashes. An ME for Busl will:

A.
already be running on Server2. When Server1 recovers, an ME for Busl will start on Server1.

B.
start on Server2. When Server1 recovers, a second ME for Busl will start on Server1.

C.
start on Server2 but fail back to Server1 after Server1 has recovered.

D.
start on Server2 and continue running on Server2 even after Server1 has recovered.
