With Oracle 8.1.7, Solaris 8 OS.

I have a shared storage device for storing all my datafiles, control files, redo logs, archive logs, etc.. everything except for the ORACLE_HOME and Oracle binaries.

If I have the file system and database mounted to one machine, and have a fully open, available database running. What happens if someone else tries to mount the same files to another machine and start up the same database on it. (No OPS or RAC involved)

I get the following error on the on the second machine...

SVRMGR> ORACLE instance started.
Total System Global Area 272359584 bytes Fixed Size 73888 bytes
Variable Size 88678400 bytes
Database Buffers 183427072 bytes
Redo Buffers 180224 bytes
Database mounted.
SVRMGR> ORA-00283: recovery session canceled due to errors

ORA-01122: database file 1 failed verification check
ORA-01110: data file 1: '/fs1/oradata/db1/system01_raw.dbf'
ORA-01207: file is more recent than controlfile - old controlfile

SVRMGR> alter database open
*

ORA-01122: database file 1 failed verification check
ORA-01110: data file 1: '/fs1/oradata/db1/system01_raw.dbf'
ORA-01207: file is more recent than controlfile - old controlfile

SVRMGR> Server Manager complete.
EXITING 1
Unable to start Oracle instance

Will this corrupt the database? Will it harm/corrupt the original instance? What happens if someone tries to recover it at this point? Does it make a difference whether its a RAW or cooked file system?

Any help is appreciated!
