Beth,

This is one of those conditions where not backing up everything gets one in trouble, on occasion. What I believe you'll have to do, which would be true in any case, is rebuild the control file. Now I'm not absolutely certain, but I do believe you can issue a "alter database backup controlfile to trace" command on a mounted database. That will at least give you the script you'll need.

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
