a successful backup cos, we have a script which reads in the list of filesystems from a file. what happened is that this file was not updated to reflect the latest filesystem. so what happens is that the backup automatiaclly will not backup it since the filesystem file did not register the new filesystem.


anyway....


the good news is we managed to get it up and running without offline any datafile.

steps
1) copy the datafile to the restored database
2) startup
3) of course, there will be errros
4) re-create control file
5) recover database using backup controlfile until cancel
6) will prompt for which online log file
7) alter dataabse open resetlogs;
8) and it works
9) smile
