Do u have a consistent backup of the database ?? If so, restore the same and issue the command :

recover database until cancel;

When all the archived logs have been applied, issue the command :

alter database open resetlogs;

This should create the online redologs.

Hope this helps,

Samir

Hi everybody,

This all started with the halon firing in our data center last night around 10pm so you can imagine my condition.

I lost a disk that contained only redo logs.

When I try to open the database I get

ORA-00313: open failed for members of log group 1 of thread 1
ORA-00312: online log 1 thread 1: 'F:\ORACLE\ORADATA\OWBREPOS\REDO01.LOG'
ORA-27041: unable to open file
OSD-04002: unable to open file

I thought what I needed to do was switch the log files, drop the members that are on the bad disk, and then I'd be able to open the database.

So I mounted the database and did

alter system switch logfile;

and its telling me ORA-01109: database not open

I thought I could swicth logfile with the database mounted?

Could someone suggest the right steps I should take to recover?

Many TIA,

Beth
