Recover Database Using Cold Backup
Dec 7, 2007
I have an oracle 8i recovery scenario. I have database cold backups of MONDAY and WEDNESDAY evenings. backup contains control files, data files, redo files
Database runs in Archive log mode and all archives of the month are available. Hard disk crashed on SATURDAY
all archive logs are still available at different location. Control files are not backed up to trace or file name or automatically means no backup control file (except ones in cold backups described above)
restoring all files from cold backup of either MONDAY or WEDNESDAY (I recovered to Wednesday) leaves nothing to recover. Querying V$RECOVER_FILE returns nothing. All log sequences higher to the number nnn displayed as result of ARCHIVE LOG LIST are present at correct location in correct format
My question is how do i ROLL Forward the Database from WEDNESDAY to SATURDAY in the above scenario.

I've got a database I need to restore from a cold backup, but I don't have a copy of the multiplexed members of the redo groups - each group has 2 members, and we've only got a backup of the first.
I know this won't stop the database from starting, and I can recreate them, but for ease can you copy and rename a redo log file from a multiplexed copy to correct location like you can with a control file?

I have the following situation: a customer sent me a group of files, that he said to be a "backup" of an old database, that is no longer online (he doesn´t use our software anymore). However, he needs to recover the data in this database. The person at the company who generate these files doesn´t work there anymore, so we don´t have any of the following information:
- Database version, connection details, service names, user names neither tablespace names.
We were just told that these files were recorded in a DVD, and is que only source remaining.
The files he sent are the following:
ctrlcf_satp_01.ctl
ctrlcf_satp_02.ctl
ctrlcf_satp_03.ctl
daddf_satp_dad_01.dbf
[code]......
Is there a way to access this data? Or can I tell our costumer that your data is lost forever..

Does the full cold backup of rman include online redologs?
So that at the time of recovery when i restore the database the online redologs also restored to that point?

multiple disk failure, the database was open at the time.We have managed to recover the data from the disk and have put it on another disk.We have got a new server with oracle 9 running.
A blank database has been created.I have copied the control files and redo files onto the new server and left the datafiles , (.dbf,.ora) on a seperate external disk F drive (this is because the original database resided on F drive)I can mount the database , however when I try to open it I get the following
ORACLE instance started.

Fixed Size 453492 bytes
Variable Size 109051904 bytes

I am doing some test, seeking your expert opinion.I have a database and have the following backup strategy.
1) Database running in archive log mode.
2) First I backup all the table space excluding one tablespace 'DP_TS_LOB'.
RMAN> CONFIGURE EXCLUDE FOR TABLESPACE 'DP_TS_LOBS';
RMAN> BACKUP DATABASE;
3) I take a separate Backup of DP_TS_LOB tablespace.
RMAN> BACKUP TABLESPACE DP_TS_LOB;
4) I backup all the archived redo logs.
RMAN> SQL 'ALTER SYSTEM ARCHIVE LOG CURRENT';
RMAN> backup archivelog all delete input;
Now I wanted to restore the database from the backup excluding the DP_TS_LOB and bring it up and running. DP_TS_LOB is huge and used only on certain work flows. I don't want the database to be down until we restore DP_TS_LOB. I wanted to restore all the other tablespace and bring the database up operational and restore and recover the DP_TS_LOB tablespace datafile's in background taking the datafiles of DP_TS_LOB tablespace offline.I tried the following but unsuccessful.
RMAN> restore controlfile to 'g:ctl_bckctl_01' from autobackup;
RMAN> restore spfile to 'g:ctl_bckspfile' from autobackup;
RMAN> sql "create PFILE = ''G:ctl_bckPFILE'' from SPFILE = ''G:ctl_bckSPFILE''";
Update the new parameter with new control file name. Copied the control file and parameter file to corresponding location.
RMAN> startup nomount pfile=D:appdivaproduct11.1.0db_1databasepfile;
RMAN> restore database skip tablespace 'dp_ts_lob';
RMAN> alter database mount;
RMAN> sql 'alter database datafile 8 offline'; ==> datafile of DP_TS_LOB tablespace.
First I assumed "Recover Database" will only recover online database files. But got the following error.
RMAN> recover database;
Starting recover at 27-JUL-11
using channel ORA_DISK_1
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-03002: failure of recover command at 07/27/2011 18:23:03
RMAN-06094: datafile 8 must be restored
Then I tried recovering data file separately, but same error.
RMAN> recover datafile 1;
Starting recover at 27-JUL-11
using channel ORA_DISK_1
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

URL....I'm practicing for the OCP test and one of the questions is that there is a backup from yesterday and the last archived logs are from the day before yesterday not mentioned if it's cold or hot backup.
If its a cold backup - cant we recover it? is it a must to have the archived redo logs also when recovering a cold backup? That sounds not logical since those logs are made only for a hot backup. URL.....

My scenario is: database is in archivelog mode.
I run DLY cold backups including controlfile & archivelogs and keep 3 gens of backups and archivelogs to 3 days also. What is the correct procedure to restore back to an old cold backup. Database is backed up Mon,Tue,Wed on Thur we require to bring database back to Tuesday DLY security.
I have tried:
startup mount
restore database from tag 'DLYTUE'
recover database
( this just rolls forward on all archive logs once it restores datafiles, not getting to point to alter database open resetlogs.)
Next tried to :
recover database archivelog tag 'DLYTUE'
( same outcome )
What is the correct rman procedure including should I remove old archive logs from working OS directory ? Also need to know once I restore back and open database to TUE security how do you tidy up the archive logs and dumps which are no longer require i.e. : weds..
I have read about using the set until time option but how to I get absolute time from when cold backup completed if this is the correct procedure.

I'm in the process of testing a restore/recover from a simulated full system and media loss. A level 0 backup was taken from the server, and I'm trying to restore/recover to a point in time on a second server. I have created the database (with the same name) and have been able to successfully restore both the controlfile and spfile from the autobackup.
how does RMAN treat the "set until time"? The level 0 was taken on a database/server that is in CST while the database I'm trying to do a restore/ recover to is in EST. So when trying to do a point in time recovery, should I specify the time in EST or CST?

My scenario is use RMAN to restore and recover database to a new host.The structure of two hosts are same.
In Host A:
1. Take a full backup.
2. Import a schema which has 191 tables in order to generate archivelogs.
In Host B:
I put all the folders(backupset, autobackup, archivelog) to the same directory. But after recovered the database, i checked that schema just has 175 tables, the latest few tables are missing.
