I've a problem. My open_cursors in init.ora is 2048.
If i query (select * from v$sysstat
where statistic# = '3' gives me a value 3463
and my query (select count(*) from v$open_cursor gives me a value of 2734. Which one is correct / or what could be wrong ?
The database is 8.1.5 on Solaris.

from v$open_cursor==> implicit cursors used + distinct explicit cursors opened + dynamic cursors parsed but not closed
from v$sysstat ===>implicit cursors used + distinct explicit cursors opened + dynamic cursors opened.
Hope it is clear.

Thanks Raghu. But what does the init parameter OPEN_CURSORS indicate and what is the relation between them..!! ?

what is it
the parameter OPEN_CURSORS will state the MAXIMUM open cursors allowed in the DB. I forget what the default is but it is fairly low (5 or 10). I remember that we used to get ORA errors until I increased the open_cursors parameter.

In 7.3 , The Default Open_cursor is 50 , I think the value states the number of the cursor opened defaultly after starting the instance .
Am I right ?

it states the maximum number of open cursors per session
