I have to migrate all data for an Oracle server from the present SAN to a new SAN. It is an 11g database in production on a Linux server. Database software is on local disk but all data (including datafiles, archive logs, control files, etc) are on a SAN via NFS.
The plan is to shut down Oracle before the sysadmin copies over the data to the new SAN. Since we are using NFS, when I start up Oracle again, the change should be transparent to Oracle.
The sysadmin has been told that the redo logs do not need to be copied. It seems to me that the redo logs should be archived before the copy. Should I force a log switch (alter system switch logfile)before the shutdown and then copy the archive logs? Or will a shutdown trigger the redo logs to be archived?
