Question

I am trying to drop a tablespace in oracle 10g , using my application .

A bit about my application — In my application I can create tablespaces.

Now what happens in oracle is that when you create a tablespace , then a new user automatically gets created and is attached to the database.

When you have to drop a tablespace what one has to do is to , first drop the user connected to the database and then the database.

When I try to drop a user associated with a tablespace.
An exception is thrown by the database which is the System.Data.OracleClient.OracleException

The details of the exception are as follows – ORA – 01904 (Can Not drop a user that is currently connected)

The thing is I have closed all the connections.Pretty sure about this.

Still oracle is throwing this exception.

Any suggestions???

Still it is not able to drop the user and throws the exception.

It can happen that you closed applications but did not ended Oracle sessions for that user. Log in as sysdba and query active sessions:

SQL> select sid, serial#, username from v$session;

       SID    SERIAL# USERNAME                      
---------- ---------- ------------------------------
       122       2557 SYS                   
       126       7878 SOME_USER                      

If you find your user in this list then kill all his sessions:

SQL> alter system kill session 'sid,serial#';
