I know this is probably a simple thing. I installed Oracle 7.3.4 on an NT Server selecting all of the defaults. It automatically creates a lot of tiny rollback segments and put them online. The application I installed required larger segments, so I created a couple of larger rollback segments and deleted the default smaller segments. These work great for the application, but when the machine gets its weekly reboot, those new segments default to offline. <br><br>Using Oracle OEM, how do I set those segments to automatically go online?<br><br>Thanks in advance...<br><br> <p>Terry M.
