Note
This view was renamed from GV$PLAN_CACHE_PLAN_STAT to GV$OB_PLAN_CACHE_PLAN_STAT starting from V4.0.0.
Purpose
The GV$OB_PLAN_CACHE_PLAN_STAT view displays the status of each cached object in the plan cache of all tenants on all OBServer nodes.
Notice
This view caches not only SQL plan objects but also PL objects, such as anonymous blocks, PL packages, and PL functions. Some fields are only valid for specific object types.
