The Oracle9i release 1 (9.0.1) Real Application Clusters features and enhancements described in this section are part of an effort to simplify application deployment. Real Application Clusters is a new architecture offering scalability and high availability features that exceed the capabilities of previous Oracle cluster software releases.
You can deploy a wide variety of application types on Real Application Clusters without significant code modifications.
You no longer have to assign locks to datafiles or partition your application when launching applications on Oracle cluster software. In addition, Real Application Clusters introduces direct cache-to-cache block transfers to improve performance.
V$GCSHVMASTER_INFO
for Global Cache Service resources except those belonging to files mapped to a particular master
V$GCSPFMASTER_INFO
for Global Cache Service resources belonging to files mapped to instances
V$HVMASTER_INFO
for Global Enqueue Service resources
These views track the current and previous master instances and the number of global cache (V$GCSHVMASTER_INFO
) and global cache resources belonging to a file accessed frequently by a single instance (V$GCSPFMASTER_INFO
), as well as the number of re-masterings of enqueue (V$HVMASTER_INFO
) resources.
