Even if you switched current, or all before shutdown?

Related to this...  we were testing some recovery scenarios for a "tech night" this past monday night and walked through controlfile recovery among other things...


Even if you have a clean database shutdown (immediate) and restore *only* your controlfiles, we found that you still need to process the last online redo log then open with resetlogs.  If you just say CANCEL then it won't open the database.  This is interesting because your datafiles do not actually need recovery.  However Oracle makes you process that last online log and open with resetlogs.  My theory is that Oracle doesn't actually update the SCN in the control file until it "recovers" a logfile...  even if there's nothing in that logfile to actually process...


FYI, we were testing on

ORA-00600: internal error code

The "USING BACKUP CONTROLFILE"  tells Oracle that the SCNs in the
Controlfiles are NOT
the current ones .  Oracle keeps prompting for as many archivelogs as
you have available because
it does not know how many you really have.
[Say that on Wednesday you restore the databasefiles as of
Monday.  You also do not have the "current"
controlfile of Wednesday. You have had to recreate the controlfile
and tell Oracle that you are
using a Backup Controlfile.  Oracle then doesn't know if you have
ArchiveLogs for Monday and also
ArchiveLogs for Tuesday and also ArchiveLogs for Wednesday.  You may
have Monday's files
and Tuesday's files but not Wednesday's ArchiveLogs. Oracle just
doesn't know because the
"current" status is not available in the controlfile that you have
Oracle keeps prompting for the next archivelog until you have applied
all your archivelogs
at which point YOU as the DBA must say CANCEL  and then OPEN RESETLOGS.

Why Archivelogs ?    Again, because information is no longer
available in the controlfile
that you have intialized !    If you really have no ArchiveLogs [you
weren't running ArchiveLog !]
just say CANCEL and then OPEN RESETLOGS.

In all cases, ensure that you HAVE CORRECTLY CREATED THE CONTROLFILEs,
naming every DataFile  -- once you OPEN, Oracle does a Data
Dictionary check and any
datafile in the Data Dictionary but not in your Controlfile becomes
a   "MISSING" datafile !
{so sometimes we do another backup, if we can, before the OPEN RESETLOGS

Having said all that, why are you sure that you DID need to recreate
your controlfiles
and reset your online logs ?  Was the problem something to do with
mountpoints and
permissions only ?
