V$DATA_ACCESS_URL_STATS and GV$DATA_ACCESS_URL_STATS Views
When a Table Hyperlink is accessed, CPU time, User I/O wait time, are updated
in the V$DATA_ACCESS_URL_STATS view.
The GV$CLOUD_LINK_ACCESS_STATS view contains the additional
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.
