V$SESSION_CURSOR_CACHE

This view displays information on cursor usage for the current session.

Note: The V$SESSION_CURSOR_CACHE view is not a measure of the effectiveness of the SESSION_CACHED_CURSORS initialization parameter.

Column	Datatype	Description
MAXIMUM	NUMBER	Maximum number of cursors to cache. Once you hit this number, some cursors will need to be closed in order to open more. The value in this column is derived from the initialization parameter OPEN_CURSORS.
COUNT	NUMBER	The current number of cursors (whether they are in use or not)
OPENED_ONCE	NUMBER	Number of cursors opened at least once
OPEN	NUMBER	Current number of open cursors
OPENS	NUMBER	Cumulative total of cursor opens minus one. This is because the cursor that is currently open and being used for this query is not counted in the OPENS statistic.
HITS	NUMBER	Cumulative total of cursor open hits
HIT_RATIO	NUMBER	Ratio of the number of times an open cursor was found divided by the number of times a cursor was sought
