Alistair Thomson from Xynomix wanted to do oracle 9i monitoring after installing the trial version of ManageEngine Applications Manager on Windows XP Pro. But unfortunately, the Tablespace status and Table space usage areas showed no data or error.
Alistair soon reported that it might be an Oracle version issue. After upgrading to Oracle 220.127.116.11 from 18.104.22.168, the problem was fixed. All tablespace information was now appearing in the monitor window.
Kudos to you .. Alistair Thomson!
