Recently, we bounced our database for maintenance.  When it came back up, we had open_cursors set to 1000.  Last night, some of our clients didn't get their reports because maximum open cursors was exceeded.  I set open_cursors back to 5000, the value before the database was bounced, so they could run the necessary reports.  One of the developers made this comment "  We do close the connection and that closes associated resultsets also. The connection is passed to ReportSessionBean.writeReport() and is closed in finally clause. ".  A few questions come to mind:

 

1.  Does closing a connection really close the associated resultsets?

 

2.  5000 open_cursors seems excessive to me.  How do I determine if this is really what's needed or do we have other "code" options?

 

2.  What can I do to help my developers?  I'm new to the development DBA world and not familiar with Java yet.  Also new to the company so I don't understand all the code relationships yet.

 

3.  What effect do all these open cursors have on my database?  Can we improve our efficiency/performance by explicitly closing cursors?

 

I would appreciate any insights.
