Failed when executing ALTER DATABASE

124626Feb 28 2004 — edited Feb 28 2004
I am trying to convert the character set from US7ASCII to WE8MSWIN1252. I connect through sql and start the database in restricted mode.

I then execute the following command:

alter database character set internal_use WE8MSWIN1252

But every time I do this, I get the following message:

ORA-12721: operation cannot execute when other sessions are active

When the database is started in restricted mode, any mode actually, there is always 8 background processes actively running. I cannot seem to kill those sessions which seem to be preventing the alter database command to execute.

I am on a Windows box if that is of any help.

Thanks in advance for any feedback.
