External security when Application Performance Analyzer is in a sysplex group

When Application Performance Analyzer operates as a member of a sysplex group, it must use the same security method (Internal, External, or External(Compat)) as the other members of the group. The first Application Performance Analyzer member to initialize sets the security method, all other Application Performance Analyzer members that start must use the same method or they will fail. In addition, it is highly recommended that the External security method be used by all members. Internal and External(Compat) will not produce desired results and are only supported for backward compatibility.
