V$CLOUD_LINK_ACCESS_STATS and GV$CLOUD_LINK_ACCESS_STATS Views
V$CLOUD_LINK_ACCESS_STATS tracks the elapsed time, DB CPU
time, the number of rows retrieved, the number of executions, and the unique database
identifier of the database accessing a registered data set.
In addition to the V$CLOUD_LINK_ACCESS_STATS information, the
GV$CLOUD_LINK_ACCESS_STATS view contains an extra column named
INST_ID of data type NUMBER. The
INST_ID column displays the instance from which the associated
V$ view information was obtained. The INST_ID
column can be used as a filter to retrieve V$CLOUD_LINK_ACCESS_STATS
information from a subset of available instances.
The unique database identifier does not disclose the OCIDs (Tenancy, Compartment, Database). This information can be used for auditing an Autonomous Database.
