Build standby database using cold backup on a different file system & host

Hi gurus,
The database version is 11.2.0.3. OS is HP UX Itanium 11.31
I am building a standby database using cold backup of primary. The primary mount points are (/p003/oracle, /p004/oracle) on HOST1 and the standby file system on HOST2 are (/s003/oracle,/s004/oracle). I am not using Data Guard to apply logs as we have a script that mounts the log location periodically to standby server and apply the logs to make it current. I am using cold backup as the database is small like 200G and can be taken down. Could someone help me with the steps to build standby using cold backup for a different file location in standby ?? My concern is I can copy the data files from /p003 to /s003. How will I build the controlfile ?
If it was same File system on both HOST 1 and HOST2 I can copy the cold backup to the standby server, build a standby control file on primary and copy and replace the standby control file and everything was set.
Thanks

Hello;
I have a note on this using a cold copy of the current files instead of a copy backup :

Recover database using cold backup

Hi All,
One of the table is delete by one of our DBA from PROD accidentally. We have a cold backup on one day before.
Now we are trying to restore it from the cold backup. PROD DB is in archivelog and all the archive is in tact.
The table got truncated today at 8 PM. Can we apply the database till 8 PM so that we can restore the truncated table using cold backup.
Please find the below steps which we are using to restore.
creating controlfile
starting the db in mount state
recover database;
Will it ask for latest archive log when we try to recover it.
ENV details -
DB - 11.2.0.1
Please suggest.
Thanks

Hi,
If you have doubts about the procedure to use to restore a backup to a point in time, then please take a look at the documentation first: Performing Flashback and Database Point-in-Time Recovery - 11g Release 2 (11.2)
After you specify the time when the recovery must end (UNTIL clause in rman), then the RECOVER command will try to use the archivelogs needed.
Before starting with this PITR operation, you should check if your database has flashback active, because it will be much easier to recover using it.
This is also explained on the same document linked above.

Recover database from cold backup and add ol archivelogs....

1. Kill current instance with SHUTDOWN ABORT.
2. Copy all control files and data files from your cold backup to original destination.
3. Make sure all archived redo logs from 01-JAN to 04-JAN are available in the database archive destination (LOG_ARCHIVE_DEST or LOG_ARCHIVE_DEST_x).
4. Run as SYSDBA:
startup mount
recover database using backup controlfile until cancel;When prompted for something like

Database cloning using cold backup

Hello Guys,
I am doing cloning of a database from cold backup for testing, actully one datafile has been croupted, so my issue is that, can i exclude tht datafile from controlfile when creating the controlfile and is that poosible that controlfile will created sucessfully and database will open sucessfully.
Please reply.
Thanks

@asif, @ckpt
With humble, how all you know that corrupted datafile is not belonging to system and undo tablespace? If this case, then do you think we can restore that corrupted cold-backup ? Sorry, but this is not the way to just start providing help without asking OP :
1.Current Oracle Version ?
2.Where he want to restore i.e. restoring platform info Oracle version OS ?
3.After cold backup how he came to know that one datafile is corrupted ?
4.When and how datafile became corrupted ?
5.How he taken cold backup ? Was db running fine just before shut immediate for cold backing ?
6.What he has done so far to restore the cold backup ?
7.What error he is getting right now ?
Here problem is corrupted datafile. So, first let come problem clear from OP, ask all missing question in one go, and then start helping is the right way... (my personal opinion, may be wrong!).

Upgrade 10.2 to 11.2 manualy using cold backup copy on new server.

Hi,
I am going to manually upgrade my databases to 11.2 from 10.2. I will use cold backup of 10.2 and copy in to the new server Red Hat Linux 5.
I got a Note (742108.1) done for upto 10.2.0.5 and it tells to set
orapwd file=$oracle_HOME/dbs/orapw<SID>
But my upgrade path is 10.2 to 11.2 and i would like to verify whether i need to do the same before startup in upgrade mode?? Nothing mention regarding this in Upgrade Guideline. Just telling only to copy password file to $oracle_HOME/dbs/
if so how i set it ? i mean in $ prompt or SQL Prompt?

I have 10 databases in one server and 2 seperate servers. I will do 3 changes mainly 32 bit to 64 bit, Suse Linux 9 to red Hat Linux 5 and 10.2.0.4 to 11.2.0.1
So best path to do all at once is cold backup and i verified it from oracle Support as well. because 32 bit o 64 bit conversion will automatically happend when upgrade.
My databses are nearly 300GB each and not much big . use for datawarehouse.

Recover datafile using cold backup in archivelog mode

Hi,
I have lost one of my datafiles i.e New.dbf from the disk. I have full database cold backup of last sunday. Also I have the archives. Is it possible to restore and recover only the lost datafile? Please help.

If you used RMAN to create the backup, then use RMAN again to restore that one datafile alone (RESTORE DATAFILE n) and then recover it (RECOVER DATAFILE n).
If you didn't use RMAN but you are sure that the backup was a COLD Backup, manually restore the datafile and then issue a RECOVER DATAFILE n from the SQLPlus command.
In either case you must ensure that the datafile is OFFLINE before you restore the file -- or take it OFFLINE with ALTER DATABASE DATAFILE n OFFLINE IMMEDIATE before doing the restore.
After the RECOVER is completed, you must bring it ONLINE with an ALTER DATABASE DATAFILE n ONLINE

Using Cold Backup for a 42GB database

I plan to have a Cold backup for a 42GB db (v 8.1.6). Since it's size is quite large, i am not sure how to back it up quicker.
I did a trial copy for a 3GB file, it took almost 9 hours to finish.
Please help!!!
Thanks a lot :)
Tracey

I did a trial copy for a 3GB file, it took almost 9 hours to finish.Wouaw, what is your network ?
You can copy the files in local, restart db, and move files on an other drive trough network, like this, the service is not down for a long time.

How to Create new database from cold backup files.

Dear Experts,
I have an oracle 10g databae on windows 2003 server.
The database is in Archive log mode and backup strategy is Taking cold backup ever night.
Backup steps:
shut down database.
copy data files, control files, redo logs, archive logs and parameter files to safe location.
Startup.
I have taken a backup at Tuesdaay 1AM and I have archive logs also.
On Wednesday, I want to Create a new database on another server with the available cold backup files and archive logs. I want to recover the database upto 4PM Wednesday. How can I do this.
I am not using control file auto backup or control file backup to trace.
Please help me how can I do this. I am new to oracle database Administration.
--Thanks

The steps :
shut down database.
copy data files, control files, redo logs, archive logs and parameter files to safe location -- you mean the alternate location for the new databaseare correct (except that I would say "alternate location for the new database").
If you do not have controlfile backups, you cannot either OPEN the database or RECOVER the database until and unless you CREATE the Controlfiles. You have to generate a CREATE CONTROLFILE script using a BACKUP CONTROLFILE TO TRACE from the Production serer and create the controlfile on the new server.
BEFORE the Startup, I would use
RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL;The "using backup controlfile" tells Oracle to continue attempting Recovery -- ie doing a RollForward -- till the last archivelog made available to it.
For the Recover command, you then keep applying the ArchiveLogs from the Tuesday 1am ColdBackup upto Wednesday 4pm.
Once you have applied the last ArchiveLog, you do an
ALTER DATABASE OPEN RESETLOGS;Here are my notes of doing a RollForward "Recovery" from a Cold Backup :
http://hemantoracledba.blogspot.com/2007/05/rollforward-from-cold-backup.html
If you are attempting all these steps on a different server from your current Production database, you should be safe.
Once you OPEN the database, you can use CREATE CONTROLFILE or the NID utility to rename the database.
If you are attempting to create the new database on the same server there are many other precautions you have to take and unless you have experience with cloning databases, I would advice you against doing so (only the RMAN DUPLICATE DATABASE command has a safer method of cloning a database).

Create a standby controlfile using cold backup

Hi All,
We have to setup a DR for a production database.
Here we have the coldbackup which backups all the datafiles and the control file from the production database.
For cloining we generally copy them to another instance and then create controlfile manually. But for setting up as a DR , we would be creating it for standby controlfile.
I tried to google but I am not able to find a way to create a standby controlfile from the existing controlfile cold backup.
OS version solaris 10 , database version 11.2.0.1

Stop and start database for cold backup

Hi,
Database :Oracle 10g R1
OS : Red hat 3
I have a RAC database with 2 nodes.
I build this script to make a cold backup of the database. (I will put it in the cron tab).
My question is the SRVCTL will work in this scripts??
# ***** COLDBACKUP ORACLE DATABASE ON LINUX *****
DIRECTORY=/u02/backup/script/; export DIRECTORY
cd ${DIRECTORY}
# ***** SHUTDOWN THE DATABASE *******
export oracle_sid=RCDB
srvctl stop database -d RCDB
# *****cold backup for "RCDB" database on 13-FEB-07 ... *****
# ***** COPY FILES *****
# Redo logs
cp /u02/oradata/RCDB/redo01.log ${DIRECTORY}
cp /u02/oradata/RCDB/redo07.log ${DIRECTORY}
cp /u02/oradata/RCDB/redo03.log ${DIRECTORY}
cp /u02/oradata/RCDB/redo08.log ${DIRECTORY}
# Datafiles
#*********START UP DATABASE AND SERVICES********
srvctl start database -d RCDB
exit

I need to put a quick policy backup ... and cold
backup it's what I use and it works.And reduces the availability of your cluster.
The problem about RMAN is that we never use it. I
have to learn about it to make scripts to test....
and this will tack me 2 or 3 days...I'd assume that installing RAC didn't go overnight, so why underfund the crucial part of any database system, the backup?
There's even a step by step guide for backup on the Getting Started: DBAs page.
Samples (and changes) on the latest version of RMAN can be found for example in RMAN Enhancements.
Or take a look at this Oracle Magazine article:Faster Backup, Faster Recovery
Backup and Recovery Basics in the user documentation may also be a good starting point.

NEED TO RECOVER A DATABASE USING RMAN with CONTROL FILE AND NO RMAN CATALOG, DISK FAILURE..

Hello All,
The disk failure caused our production data on the disk to be resotred with the backup data available and recovered through RMAN with cotrolfile , and no catalog DB is configured.
I had the restored the spfile and control file then recovered the database,
startup nomount;
RESTORE SPFILE FROM ' path ' ;
Shutdown immediate;
startup nomount
Restore controfile from autobackup;
restore database;
[AT POINT , A MESSAGE PROMPTED LIKE " failur of restored command - some targets not found" (thinking may be few archives are not found, i proceeded to incomeplete recovery of DB) ]
recover database;
Finished reocvery .
Now in the Grid control i see that 60 blocks of a particular datafile are corrupted and needs recovery. Do i need to get the data file resotred again and recover it or any simple way to recover this data file
When i perform the block recovery , it says recovery failed and when i run the data file recovery it succeeds. Please provide you inputs to recover the database as it is production BI database and pretty critical to our client.
Thanks for your valuable time in advance.
Regards,
Ran G.

These is a common problem if the object are created due to NOLOGGIN option. If you check most of the object which are facing block corruption is indexes .
Use the below query to check the objects :
It will map each block from v$database_block_corruption to either a segment or if the block is free.
$ sqlplus / as sysdba
set pagesize 2000
set linesize 250
SELECT e.owner, e.segment_type, e.segment_name, e.partition_name, c.file#
, greatest(e.block_id, c.block#) corr_start_block#
, least(e.block_id+e.blocks-1, c.block#+c.blocks-1) corr_end_block#
, least(e.block_id+e.blocks-1, c.block#+c.blocks-1)
- greatest(e.block_id, c.block#) + 1 blocks_corrupted
, null description
FROM dba_extents e, v$database_block_corruption c
WHERE e.file_id = c.file#
AND e.block_id <= c.block# + c.blocks - 1
AND e.block_id + e.blocks - 1 >= c.block#
UNION
SELECT s.owner, s.segment_type, s.segment_name, s.partition_name, c.file#
, header_block corr_start_block#
, header_block corr_end_block#
, 1 blocks_corrupted
, 'Segment Header' description
FROM dba_segments s, v$database_block_corruption c
WHERE s.header_file = c.file#
AND s.header_block between c.block# and c.block# + c.blocks - 1
UNION
SELECT null owner, null segment_type, null segment_name, null partition_name, c.file#
, greatest(f.block_id, c.block#) corr_start_block#
, least(f.block_id+f.blocks-1, c.block#+c.blocks-1) corr_end_block#
, least(f.block_id+f.blocks-1, c.block#+c.blocks-1)
- greatest(f.block_id, c.block#) + 1 blocks_corrupted
, 'Free Block' description
FROM dba_free_space f, v$database_block_corruption c
WHERE f.file_id = c.file#
AND f.block_id <= c.block# + c.blocks - 1
AND f.block_id + f.blocks - 1 >= c.block#
order by file#, corr_start_block#;
