Oops, I forgot to clarify that I have the production database in archivelog
mode, but the recovery database not in archivelog mode.

I think you may have put your finger on a possible misconception of mine.
Here is my situation/understanding.
- On production,
- Archive logging.
- RMAN backup to disk without shutting the database down.
- Not using RMAN to backup the archive logs.
- Disaster recovery scenario.
- This is a "burn the server" scenario. Imagine the computer room no
longer exists. All you have is the backup tape from the offsite storage. No
stringent recovery timeframe. If you tell the managers that it will take you
a week to recover the data, no big deal. If you tell them you cannot recover
the data because you forgot to copy some critical file to tape, that is a
big deal.
- I would assume that all of you that use RMAN have performed such a
test.
- My concept was to perform the equivalent of a cold backup/cold
recovery. Just recover using the RMAN backup set that was written to disk
and subsequently written to tape.
- What RMAN commands should I use to perform this recovery? I have
made assumptions, but they may not be correct.
- I assumed this would be an incomplete recovery since I can't
recover to the present time. So I inserted the SET UNTIL TIME command
because I think that is how you get RMAN to perform an incomplete recovery.
I picked a time just after the end of the RMAN backup.
- Do I need any archive logs under this scenario? I can change my
production procedure to use RMAN to backup the archive logs if that is what
is required.
- Do I need the RECOVER DATABASE command?
Any ideas would be appreciated. Thanks for everyone's patience while I flail
around with this.

Dennis,
This is just a wild guess and I'm probably wrong but I saw in you're
original post this DB was not in archivelog mode, try putting it in
archivelog mode and running the restore again???

Okay, I implemented everyone's comments and re-executed the RMAN
recovery.
Here is what I did and the results.
1. Action: Removed "alter database open resetlogs" from the run
statement.
Result: No change.
2. Action: Added trace=1 to the allocate channel command.
Result: No trace file is produced in udump.
3. Action: Reviewed Note 145624.1
Result: Did not see the solution to my problem. Most of the
suggestions
seem appropriate to backup rather than recovery jobs.
4. Action: Added log and debug trace statements to rman invocation
line.
Result: Produced log and trace file. The trace file at the point of
the
recovery hang contains the following:
krmxrpc: xc=5372006336 kpurpc2 returned 0
krmxrpc: xc=5372006336 RPC #10 completed immediately
RMAN-08523: restoring datafile 00006 to /ora05/ams/data0501.dbf

krmxr: callback returned TRUE, skipping sleep
krmxpoq: xc=5372006336, action="0000013 STARTED", col_l=15, ind=0,

krmxr: sleeping for 1 seconds
krmxpoq: xc=5372006336, action="0000013 STARTED", col_l=15, ind=0,

krmxr: sleeping for 2 seconds
krmxpoq: xc=5372006336, action="0000013 STARTED", col_l=15, ind=0,

krmxr: sleeping for 4 seconds
krmxpoq: xc=5372006336, action="0000013 STARTED", col_l=15, ind=0,
sid=13
krmxr: sleeping for 8 seconds
And the trace continues with this statement.
Any suggestions would be appreciated, as are the suggestions to this
point.
I'm about ready to think it is TAR time.

I am trying to perform an RMAN disaster recovery task. While I use an
RMAN
catalog to make backups, I am trying to recover using just the control
file
information.
Oracle 8.1.6, Compaq/HP Tru64
I start RMAN with
rman target sys/password nocatalog
then,
startup mount
run {
set until time "to_date('08/11/2002 01:00:00','MM/DD/YYYY
HH24:MI:SS')";
allocate channel d1 type disk;
restore database;
recover database;
alter database open resetlogs;
}
Everything appears normal for awhile. In the alert log RMAN tries to
find
each file, doesn't find them. Then it successfully recovers 5 data
files
(including system and rollback) and reports success in the alert log.
Then .
. . nothing for hours. RMAN doesn't return an error. The RMAN shadow
processes are still present but with no CPU consumption. Nothing is
written
to the alert log.
I check V$SESSION_WAIT, and the only entry for the RMAN shadow
processes is one is SQL*Net message to client with seconds_in_wait =
0,
state = waited unknown time.
In V$SYSTEM_EVENT, time_waited and average_wait are zero for all
events. The following events have values of total_waits that are
increasing:
Increase in total_waits in
10-minutes
rdbms ipc message 401
pmon timer 57
control file parallel write 56
SQL*Net message to client 24
SQL*Net message from client 24
virtual circuit status 5
dispatch timer 3
smon timer 1
Archiving is turned off.
I have attempted this recovery many times using different RMAN backup
sets,
but the system always hangs at this point.
Any ideas would be appreciated.
