Hi,

I have a .Net application with Oracle database. I received the below error while trying to run a report in my application. Request anyone to check and advice if there is a fix for this problem.
Also note that I have spoken to my DBA and he says that there is something in the .Net code that is not ending the sessions.

The error message is :

ORA-2391: exceeded simultaneous SESSIONS_PER_USER limit

Let me know if you need any more info

For DB side:

Check this
Error: ORA-02391: exceeded simultaneous SESSIONS_PER_USER limit[^]

Coding side:

There's possibilities that you didn't close/dispose the connection object properly. When you open a connection, you should close after the use & you should dispose the objects properly. Check these articles for reference
ASP.NET - How To Use(Open/Close) Connections Correctly[^]
