RE: Oracle not available???
YOur network guys may have turned off access to ports 1521 or 1575 if you are using onames to stop the spread of the worm. I used to DBA 30 some instances on several windows boxes. Both NT and 2k. Pretty much made a point of rebooting at least once a week. Did cold backups so database was down anyway and adding a reboot was easy. One box we did not reboot regularly and it would eventually crash or lose its mind. I don't think we had a windows box up for more than 120 days on windows. (patching, crashes, memory leaks, hardware failure etc...) These were canned apps and they tended to have lots of extra crap installed on the DB server so rebooting was a prudent to prevent business hours downtime. One box was rebooted nightly due to poorly designed interface between a phone switch and a database. -Original Message- Sent: Thursday, September 04, 2003 1:45 AM To: Multiple recipients of list ORACLE-L Thanks Patrice, I'll look into this, however I find it way strange that the server has been running no problems for almost three months.

No, in Task Manager. place the cursor over the task bar (at the bottom of the screen), right-click, and Task Manager will be one of the items listed. Open it, go to the Performance tab.

If the database was shutdown cleanly, the online logs are not required or desired. If the database was not shutdown cleanly, you will not be able to open the database without them.

RE: oracle not available ???
A Cold Backup is always a Full backup --- all datafiles (and, highly
recommended, all control files
and redo log files).
Did you shutdown the database twice but only backup 6 files each time ?
How many log switches
occurred between the first backup and the second ? If the transactions are
still in the online redo logs,
you might try a recovery.

RE: oracle not available ???
Maybe I don't understand what you are saying but a cold backup is the complete database. There is no part there like you can do with a hot backup. So if you only backed up part of it the first time and part of it the second time and you are not in archive mode you are screwed. However, if it is indeed a full backup then just restore your latest. -Original Message- Panyam Sent: Tuesday, January 01, 2002 11:55 AM To: Multiple recipients of list ORACLE-L Hi list I have a database recovery problem.
