Recovery using Hot Backup

We have to create a new enviornment(pre-prod) using Hot backup (restore from tape of last week) of the current prod DB, we have installed the same version of software as in prod and prepared init file but i am not sure about how we are going to do the recovery from last week backup,it would be a incomplete recovery as they want data till last week only,to my knowledge..we will create a new control file and open the DB using resetlogs...please can somebody help/guide me more on this...please share the steps required.If you have backup of one week older, then
1)startup instance in nomount status
2) check the logfile of RMAN for controlfile backup piece
or from Production give below command and check for the backup of the last week controlfile.
RMAN> list backup of controlfile;
note the backup piece
3) again back to pre-prod
RMAN> restore controlfile from 'backup piece';
5) SQL> alter database mount;
6) RMAN> Restore database;
after restore database open database with resetlogs, If you see any inconsistency apply archives 1/2 or as needed for consistency. and open database with resetlogs.
Here duplicate from active database wont work as you want 1 week older data.

ORA-01610: recovery using the BACKUP CONTROLFILE option must be done

Hello All,
I have an instance on my LAB server. To explore more avenues in cloning a DB I did the following.
1. On my Oracle 10g Instance I fired an large query which would take atleast an hour to execute.
2. Opened another session and executed shu ABORT to shutdown the above instance abruptly.
3. Took backup of datafiles, archive logs and redologs [ prior to shu abort, I had issued ALTER DATABASE BACKUP CONTROLFILE TO TRACE]
Restoration steps:
NOMOUNT with pfile edited to hold the name of the new DB_NAME
Create control file script edited to reflect the new paths of datafile and redologs.
MOunted succesfully.
ALTER DATABASE OPEN RESETLOGS;

Greetings,
If I understood, you basically have a copy of a primary database and the redo log archives of this pretty same database, you have backed up the control file of this primary database, edited it pointing all paths of your datafiles to the new location but renaming the instance name.
I am assuming that you have edited the first line of your control file to something like "CREATE CONTROLFILE SET DATABASE "DB02" RESETLOGS ARCHIVELOG", in this case are you sure that the redolog archives have not loose the sequence? In this case it will ask more and more archives and it will never end, take a look at the date and time of the thread that your instance is asking for recovery. Is your instance a production database? If it is NOT production and you are SURE that the database is completely recovered and is asking for redolog files that does not even exist you can try to add the ALLOWRESETLOGS_CORRUPTION=TRUE to your init.ora and open the db... This solution is not recommended and you should never use it on production instances... take this hint as a LAST effort to bring your db online.

RAC Cloning using hot backup

Hi,
can somebody help me with the steps for cloning 2 node to 2 node RAC, using hot backup.
Thx.

Actually, the procedure to clone a RAC database do not differ substantially from those of a single-instance database.
You can perform your cloning as if it is a single instance database and once you have your single instance up, you just have to add another instance - and the high level steps would be:
1) Preparing the init.ora file for the second instance.
2) Adding the redo logs for thread 2;
3) Updating the OCR

Dataguard setup using hot backup files

Hello,
I am planning to setup dataguard using Hot backup (Not RMAN) files from the primary instance. I have a few doubt as, How shall I recover the Standby database using the archive files generated while taking hot backup of primary? Shall I directly execute the "alter database recover managed standby database" command? Will this command take care of the archives generated durring hot backup also?
Appreciate any help on the above.
DB Version:10.2.0.4
Regards.

Guys by using below procedure you can rebuild your data gurad by using manual hot backup.
1) On the primary database, defer the archival of redo data .
ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=DEFER;
2)
put primary database in backup mode
copy all the datafiles from primary database to Standby database (you can copy to other location in primary server and tar&zip it and send it to stand by and unzip and untar there)
Once you copy the datafiles to another location on primary server,you can use below command for tar and zip
go to the copied datafiles location and issue below command
tar cvf - .|gzip -c > /dump/backup/drdb_backup.tar.gz
put primary database in end backup.
3) create stabdby controlfile by using below command and send it to standby server
alter database create standby controlfile as '/dump/drbackup/2standby.ctl'
4) copy all generated archive logs (from the time of database begin abckup) from primary database server to standby database log_archive_dest location.
5) on standby database once we placed all datafiles and controlfiles in place use below commands
export ORACLE_SID=standbydb
SQL> starup nomount;
SQL> alter database mount standby database;
SQL> recover standby database;
--AUTO
SQL> alter database open read only;
SQL> shut immediate
SQL> startup nomount;
SQL> alter database mount standby database;
SQL> alter database open read only;
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;
6) On the primary database, issue the following statement to reenable archiving to the physical standby database:
SQL> ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=ENABLE;

Hi,
What is the OS and version of Oracle?
Do you have all the archivelogs after the hot backup? Is the backup a valid backup? Is it a RMAN backup or normal file system backup of the datafiles?

I have all my archive files in the archive dest location.
Is there any way to prevent this warning messages and let oracle find all the archive files?
As you can see from the messages, Oracle is finding the correct file, then why there is an error message and why we have to provide the file names one-by one.
Please help !!!

Oracle will look for needed archive logfile from your log archive destination.
If you are sure all these files are under /d01/oradata/devl/arc/, you can input AUTO, Oracle will work down the list until done.

Hi,
I would really appreciate if you could please share with us what is the process to recovery EBS 11i environment to an alternate DR server using the latest tape backup in case any disaster happens to the existing production server.
I need to prepare and test disaster recovery plan document using the latest tape backups.
We have single node EBS 11i environment with Apps and DB installed on the same AIX Unix Server.
We also have full database RMAN backup every night.
The new alternate DR Unix server will have different hostname and IP address.
Thanks in advance.

Recovery from Online backup

Hai All,
I regularly take hot backup via a script. In script copy all datafiles and archivelogs to the backup destination. One conrolfile is created using 'alter database backup control file to c:/backup.ctl' . Thus controlfile is also generated.
I copy the backup files (includes datafiles and controlfiles) to a test machine . In test machine I created a database with the same name of production database. I replace the present files with the hot backup files (keep existing redo log files). When I open the database, recovery asked... I apply the backup archive log files. Even when reach the maximum archive files in my hand. recvery not stop... . This is the problem .. How It happened ? How to open the database with the backup files in my hand only.
I copy the remaining archive log files and redo log files from production database and apply. then I open the database with resetlogs . It works fine......
How to resolve the mentioning problem in second paragraph?
Please help?
Shiju

How do you backup your database? Do you using RMAN to backup your database? or you use ALTER TABLESPACE BEGING BCKUP method to backup your database?
Which version of Oracle are you using? Is there anything wrong configure autobackup of controlfile to avoid explicitly taking controlefile bakup?
If you want to test your bakcup or wanted to create another copy (clone) of the database using your valid backup, why did you create the second database and did the other fuss?
You can simply, bring up the instance, restore and recovery using your backups.
I guess, the problem was with redo log files. You have overwritten all the datafiles, controlfile, but not redo log files, may be the redo log sequence mismatch cuased this behaviour.

Implementing Hot Backups

HI ,
i am new to the idea of hot backups , so need abit of advice on how to implement them by using RMAN and User based techniques
a little bit abt my production environment
Oracle 9.2.0.6
EBS 11.5.10
OS is HP UX 11.11
earlier i used to get downtime of 2 hrs , so iused to cold backups wid RMAN as well OS based techniques , now due to 24 hr system requiremnt
i have to use hotbackups, DB size is 200GB, how can i use hot backups so as my system works efficiently without any extra load

Soli wrote:
Hi,
Each tablespace that needs to be backed-up must be switched into backup mode before copying the files out to secondary storage.
This can be done as shown below:
ALTER TABLESPACE xyz BEGIN BACKUP;
! cp xyfFile1 /backupDir/
ALTER TABLESPACE xyz END BACKUP;
The above would only be for user managed backups, which the OP has no reason to be doing. We should be guiding him in how to use rman, not in how to use obsolete techniques -- ESPECIALLY since he is new to the whole subject of backups and would easily be confused by mixing the techniques.
Recovery Manager command:
run {
allocate channel t1 type `SBT_TAPE';
backup
format `df_%s_%t'
(datafile 10);
When Recovery Manager executes the above command, it sends the Oracle backup request to the Oracle server performing the backup.
The Oracle server process identifies the output channel as the type `SBT_TAPE', and requests the Media Management Library to load a tape and write the output specified.
but ther you must ask sysadm which storage you use and how to backup there.
btw.
there is link how to setup RMAN

Need some advice about hot backup under linux

hi, I want some advice about db files hot backup between two machines(Named A and B).A is primary machine which will write and read database and have the lastest db file. B is backup role and no database file in it.
Now I want hot backup A's db file to B in order to B have the lastest db file too.
At A,my db file support transaction and environment, and I set autoremove unnecessary log files.
The code such as follows:
dbenv->set_flags(dbenv, DB_AUTO_COMMIT |DB_LOG_AUTOREMOVE | DB_TXN_WRITE_NOSYNC, 1);
ret = dbenv->open(dbenv, NULL,
DB_CREATE | DB_INIT_LOCK | DB_INIT_LOG | DB_INIT_MPOOL | DB_INIT_TXN ,0)
I don't want to use db_hotbackup utility. and db_hotbackup may be backup files to the same machine with different dir.
How can I make machine A's db files backup to machine B.
Thanks for your help.
Best Regards
hangsy

Hi Hangsy
Now I want hot backup A's db file to B in order to B
have the lastest db file too.What do you mean? Do you want to have the latest version... from when you did the latest backup, or you want to keep it updated in the same time with the main database?
I don't want to use db_hotbackup utility. and
db_hotbackup may be backup files to the same machine
with different dir.You can copy the backup anywere you want.
If you want to run recovery on a different machine, it must be the same pointer size and endianness as the original machine.
Database and log file archival: http://www.oracle.com/technology/documentation/berkeley-db/db/ref/transapp/archival.html
It is usually simpler to take the hot backup on the main machine and run recovery there before copying the databases to the remote system.
In this setup, only the databases are required on the remote system, not the log files.
Since you are using NOSYNC, you should run a checkpoint which will ensure you that the database files are up to date.
Please read "Recovery procedures" ( http://www.oracle.com/technology/documentation/berkeley-db/db/ref/transapp/recovery.html ) first. "you cannot perform a hot backup of databases and log files, restore the backup and then run normal recovery -- you must always run catastrophic recovery when using hot backups."

Unique Error while doing hot backup Cloning!

Dear All,
I am using EBS 11.5.10.2 with DB 9.2.0.6.
I am doing hot backup cloning by referring *[Cloning Oracle Application 11i /R12 with Rapid Clone - Database (9i/10g/11g) Using Hot Backup on Open Database|https://metalink2.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=760772.1]*
I am facing a unique issue, when I run adcfgclone.pl dbconfig <my_context_file>, application of my Production Server start misbehaving and it gives me an error:
Node Id does not exist for the current application server id.When I check the FND_NODE table I found that there server id was empty in it.
I have to run than run the following steps as the resolution:
1. Shutdown all the services.
2. EXEC FND_CONC_CLONE.SETUP_CLEAN;
3. COMMIT;
4. Run AutoConfig on all tiers, firstly on the DB tier and then the APPS tiers,to repopulate the required system tables.
5.start all the services and verify the issue.
Than application behaves normally.
Is there any additional step to be followed while Hot Backup Cloning other than mentioned in the above mentioned ML Doc?
Please suggest,
Anchorage :)

I am facing a unique issue, when I run adcfgclone.pl dbconfig <my_context_file>, application of my Production Server start misbehaving and it gives me an error:
Node Id does not exist for the current application server id.Where did you get this error?
This is very strange, how come this happens in Production, when you are doing cloning in TEST/DEV instance.
Is there any additional step to be followed while Hot Backup Cloning other than mentioned in the above mentioned ML Doc?I feel there are no other additional steps, as I Recently did successfully hotbackup cloning using the same document.

Hot backup slow

Hi,
I am working in oracle8i.We are using hot backup in our database. Normally it takes 2 hrs to complete the backup process.
but today it took 5 hrs to complete the backup process. Kindly let me know what are the possible ways to identify the solution for taking more time.
Rgds.

Hi,
There could be any number of reasons for the backup taking longer - but here are a few likely candidates:
The server was busier than usual - run top to see if anything unusual is hogging CPU.
The database was busier than usual - did someone run a large report/update
Tape drive contention - do you share a tape device with another app?
The database has grown significantly.
Cheers,
Andy Barry
