thxs"while i cannot c the datafiles thoes r on san"
I guess that must some shorthand for "I cannot see the datafiles, those are on san."
If so, what does being on san have to do with being able to see the files?
In any event the answer to any question about "how do I backup" is the same .... RMAN.

Oracle R12 12.1.3, how to make cold backup

Hello guys
After a month long efforts, I was able to deploy the 12.1.3 templates successfully and the full vision instance is accessible without any technical hickups. I have setup VM Server 3.1.1 and VM Manager 3.1.1 using Oracle VirtualBox. The application is running on a two node structure now and I would like to take cold backups for both apps and database tier, later merge them to a single node and move to Oracle Linux 6.2/6.3 so that I could take it around in my laptop for demonstration purposes (We are on 12.0.4) right now and dwelling the possibilities of migrating to 12.1.3)
regards,
raj

I already have two node application R12 (12.1.3) structure, now what I want is
I want to take a cold backup of application tier, and database tier.
Then move the backup to a new server and setup a single node, which will be on Oracle Enterprise Linux 6.2
So, basically I want to know how to take a cold backup and then setup a new server with the backup.You can use any of the commands mentioned in this link -- http://www.oracle-base.com/articles/misc/os-backup-commands.php
You might also use rcp/scp.
http://linux.about.com/od/commands/l/blcmdl1_rcp.htm

Please note for cold backup you will need to shutdown the application/database properly (clean shutdown).
Thanks,

How to take a backup manually in oracle 11g express edition?

how to take a backup manually in oracle 11g express edition? i want to take backup of a database and want to restore later on on a different computer .

Stop database, and copy all files to another machine.That sounds to me to be the closest answer to the question posted. And perhaps the easiest solution.
Install XE on the "another machine", shut it down. Shutdown the source database. Copy the datafiles to the new host. Startup your "new" database, it will be an exact clone of the original.
To find out what files need to be copied, as system (or sysdba) run:
select name from v$datafile;
... file1, file2 ...
show parameter control
... control_files ... file1 ...
alter database backup controlfile to trace [reset logs];
show parameter diag;
... diagnostic_dest ... <drive:>|/diag_pathTo do a proper database clone its better to recreate the controlfile and reset the archive sequence number- leave out the controlfile copy part. In the diag_path location find the trace file under diag/rdbms/$ORACLE_SID/<db_name>/trace it should be the latest ora*.trc file.
The trace file has the commands to recreate the controlfile, which includes the datafiles and putting the tempfile back in place. If the datafiles are in a different location, i.e. in Windows going to a different drive, or you want do put datafiles in a different folder location, the create controlfile statement is the easiest time to get the file directories right.
If you add the "reset logs" qualifier (don't use the brackets!) you'll get just the reset logs version of the create controlfile statement, otherwise you'll get both NORESETLOGS and RESETLOGS versions of a create controlfile statement, run one or the other. Not both. Not the entire trace file, just the create controlfile, alter database open [reset logs], alter tablespace temp add tempfile ... bits. No recovery is needed for a database that is shutdown when datafiles get copied to a new location/host.

How to take schema backup

Hi All,
Can you please tell me how to take schema backup.
DB : 10.2.0.2
Thanks in advance.

1. 1. what is the time difference between for this two utilities to export the data for a schema, i.e "expdp" and "exp"?Go for EXPDP
2. If i using COMPRESSION option in "expdp" utility, how many times data size will be reduced to original size?When “Y”, export will mark the table to be loaded as one extent for the import utility. If “N”, the current storage options defined for the table will be used. Although this option is only implemented on import, it can only be specified on export.
3. 3. With out importing the data, how can i check the data which is exported, is correctly exported or not? You can do import with show=y option. This will not import any thing in the database. this will only generate the Sql file and your Export file can be validated. This will work similar to normal import except that this will not insert anything in the database.
Imp 'userid/password' fromuser=userid touser=userid show=y file=filename.dmp log=logfile.log

How to restore cold backup + archived log files

Hi,
Suppose I take a cold backup on 18th. After that I have four days of archived log files. if the database crashes on 5th day, I have to restore the 18th cold back + 4 days of archived log files. How do I restore since it is a cold backup and I cant do incomplete recovery.
can I use
Recover database ( with 18th cold backup) in mount state and apply archived logs.
Prabhath

The details of how you perform forward recovery using a cold backup depends on
1- rman or manual backup
2- using current or backup control file
3- if rman, recovery catalog or no recovery catalog
4- if full database recovered or only a few files
Each of these conditions will affect what is known to Oracle and what needs to be done. For example if you restored the entire cold backup including the control file then Oracle would see a consistent database and not need to perform recovery so you would need to startup mount and tell the database to perform recovery using a backup control file. If using rman and no recovery catalog you might need to catalog some of the archived redo logs, etc....
It is advisable to consult the Backup and Recovery manuals before attempting recovery for any new scenario.

How to take Auto backup from External Network Drive to Mac pro internal Dri

Hi,
I have a External Network Drive (Buffalo 1TB) which i use as a server, now i need to take auto backup from that external drive to the Mac i am working on, which has 2TB Internal hard Disk.
Please could anyone help me on this.....
Thanks in advance

If you are looking to actually integrate what you have on the external one terabyte hard drive with the 2 TB hard drive you're using inside the Mac the best move for you if you want access to that data when using the Mac Pro server is going into utilities click on the top bar where it says go fall that down to the utilities told them that folder quickly once you are there you will see migration assistant click on that you will be asked to type your admin password to that. It will ask you "how do you want to transfer your information" then select from a Time machine backup or other disk when it asks you will be transferring information to your Mac Pro from your 1 Tb backup external hard drive once it's finished eject the drive or reformat it and use it again if your objective was to infect keep compress the data on the external so you have more space but do not have access to it I strongly recommend Carbon Copy Clone 3.3.1 is 100% free and does a fantastic job here is the link http://www.pure-mac.com/downloads/carboncopyclonerdl.html of copying every block to create an exact replica of your source hard drive. If you want something different and don't mind paying SuperDuper! is a great product as well this WebSite will have many options I would stick to carbon copy clone http://www.pure-mac.com/backup.html I also like EMC Retrospect backup and recovery software for the Mac it is a great product but very much on the expensive side for backup utilities although if you need word offers this might be right up your alley.
I hope I wasn't help,
Sincerely,
Thomas

How to take the Backup of all XI-Design Objects(Repository, Directroty,SLD)

Deal All,
Actually I am facing problems with XI Server.
we have decided to reinstall the server. So, please tell me how to take the back up for all the scenarios that has been created in that. And also tell me how to take the back up for all the things.
Then how the backups can be used in Newly initialed XI-Sys.
Please help me.
Thanks in advance.
Danab

Hi,
In your IR and ID , you can export the Objects as TPZ files which can be reimported later.
To expoert, select the SWCV in your IR or the Configuartion Scenario in ID and then Tools --> Export and then specify the directoy in your XI server to which export should be done and then export the same.
Now, they will be available as TPZ files. When you need to reimport, tools --> Import and you can import.

How lot take log backup using script in HANA

We have SAP HANA SPS09.
1) We are using script provided by SAP Note#1651055 to take the data backup.But it seems it is not taking log backup.HOw can we schedule logbackup ? or we have to use DBACOCKPIT or Studio only?
2) My DB is log_mode OVERWRITE.I have taken backup using script.But when I tried to check the backup using below command
hdbbackupdiag --check -f -d /mnt/resource/backup/xb8_bkp_19022015/ --logDirs /mnt/resource/logbackup/,/usr/sap/XB8/HDB00/backup/log
ERROR: [110081] Catalog backup log_backup_0_0_0_0 not found

Is it like we have the DB in OVERWRITE mode thats why we are getting this error?Will my recovery work ?
Thanks,
Mofizur

Did your issue got resolved?
We are having same issue. We are on Rev 82 and using DD Boost EMC to take the backup using BACKINT.
Though we are on Rev 82 I tried option provided by Pavan which didn't worked for me.
hdbbackupdiag --check --useBackintForCatalog --backintDataParamFile /opt/ddbda/config/sap_hana_ddbda.utl -d /usr/sap/A0T/SYS/global/hdb/backint

How to take RMAN backup through a single (default) channel

Sir,
In an interview I was asked a question that how can I allocate a single channel to multiple databases to take simultaneous backup. I was unanswer.
Pl. tell me if it is possible what will be the query with an example.
Regards
Neeraj

No it's not at all possible to take backup of multiple database through the manually allocated channel.
Allocating the channel manually is only possible while running the commands in batch mode
eg. run {
allocate channel ch1 type disk format='/backup1/RMANBACKUP/PROD521_%s_%p';
allocate channel ch2 type disk format='/backup1/RMANBACKUP/PROD521_%s_%p';
backup database setsize=12582912;
release channel ch1;
release channel ch2;
And you can connect through single rman prompt to only one target database not more than that. So at any point of time you connect to only one database you can user channels to backup that database only.
connected to recovery catalog database
RMAN> CONN TARGET SYS/ORACLE@RMAN
RMAN> CONNECT TARGET SYS/ORACLE@RMAN
connected to target database: RMAN (DBID=1528877161)
RMAN> CONNECT TARGET SYS/ORACLE@CLS
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-06167: already connected

How to restore cold backups on other server

Hi all
On Oracle9i production server, we have windows scheduled job to take the cold backups every day night. The size of the database is 2GB.
Now, the cold backup consists of
- Database files & Log files
- Parameter file
- Control file.
I am required to check the validity of the cold backup we have. So, I need to restore the database in another server.
So, please provide me the steps I need to do to restore the database.
Thanks.

"Oracle9i User-Managed Backup and Recovery Guide Release 2 (9.2)" (Part Number A96572-01)
http://download.oracle.com/docs/cd/B10501_01/server.920/a96572/osrestore.htm#26029
Best to start with Chapter 1 "Introduction ..."

How to take list backup with lookup columns data in sharepoint 2010

Hi friends,
I have one issue on "Copy the list in one sitecollection to another sitecollection"
I have one list like "ABC" and with lookup column "Status" this column is looked to anthor list columns
My task is i want to Copy the same list with lookup columns with Data(lookup columns Data) in one site and restored in another site.
Error is Lookup columns Data is not coming.
How to Copied list with lookup columns data to restored in another list?
Badri

i think there is no such method to move the list with lookup column.
couple of things which cause the failure, Number Source list may be not available on the target site collection, Column IDs / List IDs different from Site collection a to B.
I would try to use the backup of site collection and restore it, i am not sure whether it will work not.
i think copy the data from the lookup clomn in the excel, then move the list to different site collection with blank data then copy the data from excel to new list.
check this one for another idea:

How to take client backup in development SAP server

Hi Expert,
I want to take backup Client Specific like (Ex.200) database. we are using SQL database.
1 Its very urget if possibe then please suggest me.
Points will be rewardable
Thanks @ Regards
Arpan Saini

Hi,
As far as i know a backup would be taken for the database completely,there is no such option to backup a single client.
If you want to backup a client there is no other option rather than backing up the sap system,as far as i know.
