I have ORA-01000: maximum open cursors exceeded.
Can you please help me with advice/or a script to close the cursors?

How do you access the DB?! Via JDBC or ADO...?! A common problem here is NOT closing/disposing the connection properly...
I suppose we do need more background information considering your issue...

I agree with the above post.  It is likely the code isn't properly closing and disposing of connections.

I just wanted to add that it this is in PL/SQL, it is a simple close command:

If you don't have direct control over the application code, your other option is to change the limit for open_cursors in your init*.ora or spfile to a higher value.

We are setting up the new 12c OEM.
We have the app server hosting the 12c OMS and backend is single instance oracle database.

I did change the limit from 300 to 500 hundred, but i think as suggested above i need to find how the connection to the DB is made and check the code to properly close or dispose of the connections..

Hi Shobha,

Increasing cursor limits is not a permanent solution.Just check the objects which is making the continuous connection and keep the same open.There you need to add "Close Cursor_name" condition to resolve the issue permanently.

>>Increasing cursor limits is not a permanent solution

It can be a permanent solution.  If it is decided that this is 'normal' behavior for the applications based on the number of users, then you need to tune the database appropriately.
