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
