An administrator noticed that one of the servers in the core group is experiencing OutOfMemory. As a result,
other servers in the core group failed to start.
What core group custom property should the administrator tune to prevent the affected server from impacting
other servers in the core group?

A.
IBM_CS_OOM_ACTION

B.
IBM_CS_DATASTACK_MEG

C.
IBM_CS_WIRE_FORMAT_VERSION

D.
IBM_CS_HAM_PROTOCOL_VERSION

Explanation:
IBM_CS_OOM_ACTION
Use this custom property to explicitly enable exception handlers that are specific for OutOfMemoryExceptions
that occur when sending or receiving network messages. When this property is set to Isolate, if an
OutOfMemoryException occurs when a network message is being sent or received, these exception handlers
stop High Availability Manager communications to the Out of Memory process.
If IBM_CS_OOM_ACTION=Isolate is not added to the configuration settings for a core group, if a core group
process runs out of memory, the Out of memory process might not be able to respond to all messages. This
situation prevents multi-step protocols from completing, and prevents the starting server from receiving its
initial view of the distributed state.
