Galaxy Configuration Utility 10

Single-instance Open. VMS Galaxy q. On any Open. VMS Alpha system q. GCU creates a configuration file q. System parameter GALAXY set to 1 q. System boots as single-instance Open. VMS Galaxy complete with “shared memory” q. It is not a simulator: it is the real code q. Allows Open. VMS Galaxy application development and testing 11

Compatibility q No software changes are needed to run in an Open. VMS Galaxy instance q Existing command procedures run unchanged q Existing applications run unchanged 12

Availability q Instances can be rebooted independently n upgrade software versions n AUTOGEN n expand system capacity q The entire system never needs to be down 13

Scalability q multiple instances can make better use of the machine’s resources q CPUs - distribute the SMP overhead q I/O - distribute the interrupt processing 14

Adaptivity q physical resources are dynamically reassigned n CPUs n some memory 15

Cost of Ownership q multiple instances means fewer systems, reducing n management requirements n floor space n licenses 16
