How to display open cursors in Oracle?
Problem:
You want to display open cursors in Oracle.
Solution
We can query the data dictionary to determine the number of cursors that are open per session. "V$SESSION" provides a more accurate number of the cursors currently open than "V$OPEN_CURSOR".
Example
select a.value ,c.username ,c.machine ,c.sid ,c.serial# from v$sesstat a ,v$statname b ,v$session c where a.statistic# = b.statistic# and c.sid = a.sid and b.name = 'opened cursors current' and a.value != 0 and c.username IS NOT NULL order by 1,2;
The OPEN_CURSORS initialization parameter determines the maximum number of cursors a session can have open.
