Beginning with Oracle8, the dynamic performance data dictionary views (V$ views) were augmented with a complementary set of global dynamic performance data dictionary views (GV$ views). The V$ views provide information about the instance to which you are connected and its management of the database. The GV$ views provide the same information for all other instances that have the same database mounted and are primarily of interest in a Real Applications Cluster or Oracle Parallel Server environment.
The global dynamic performance data dictionary views add the column INST_ID to their names, which allows you to identify the instance for which information is being provided.
