DB2A and DB2B are in the same data sharing group on separate LPARs There are two coupling facilities CF01 and CF02. CF01 contains the Lock and SCA structures and CF02 contains the GBP structures. The group buffer pools are not duplexed. The structures can reside on either CF01 or CF02 as specified in the CRFM policy PREFLIST and AUTOREC is set to YES.
