Hi Linda,

It has major difference. RAC based on Oracle Database cluster and HACMP based on Operating System based cluster.

Oracle RAC http://www.oracle.com/technology/products/database/clustering/index.html

HACMP - http://publib.boulder.ibm.com/infocenter/clresctr/vxrx/index.jsp?topic=/com.ibm.cluster.hacmp.doc/ha...

Hi Linda,

the major difference is that HACMP is a failover cluster with one active database instance and thus a single point of failure where RAC is an active/active cluster with two or more database instances and all of them are active.
