Performing database backup using SAPDBA

Guys could u please let me know how to take whole database backup using SAPDBA to another hard disk attached to the system (i.e rather than taking the backupto /oracle/<SID>/sapbackup on the same system i want to take the backup to another harddisk attached to the same system?)
should i change any parameter in init<SID>.DBA?

You dont need to change the init<SID>.dba.
Rather you need to change init<SID>.sap.
make a copy of init<SID>.sap and save it as for e.g. init<SID>1.sap change the value of the following entries as follows.
backup_root_dir=your desired directory
stage_root_dir=your desired directory
Now use this init<SID>1.sap as the profile parameter file in sapdba and your backup will be stored in the"your desired directory".

Error in Database backup using RMAN.

Hi
While taking full online backup using RMAN i got the following error.
ORA-19566: exceeded limit of 0 corrupt blocks for file /oracle/DEV/sapdata2/dev640_6/dev640.data6
Please help me how to resolve this issue.

Hi,
Please perform DBverify Job and Also analyze the alert<SID>.log file for your Database to get more information about such logical or physical corruption. You may require Block level recovery for the complained DB Files. Please refer this useful document " [Early Detection and Correction of Data Block Corruptions Using RMAN |http://www.ioug.org/client_files/members/select_pdf/04q4/RMAN.pdf]" and share the same with your Oracle DBA.
You can execute the following commands to get information about corrupted block(s), if its there.
select * from v$backup_corruption;
select * from v$database_block_corruption;

Scheduling a script performing database backup

I wrote a script performing a backup of all databases located on a SQL Server's instance using the Backup-SqlDatabase command. As a script from the Windows Powershell ISE it works fine. I am working on a Windows Server 2012
The next step is to schedule this from the Windows Task Scheduler. The Action program is PowerShell and the arguments is -command "& 'C:\folder\myscript.ps1'" and it doesn't work, the script appears to fire off but it doesn't
perform the backup. The error looks strange it looks like it can't connect to the SQL Instance, I tried a whole bunch of options I found googling around but none worked. What am I missing ?

1) Using -File instead of -Command didn't work, it didn't even fire the script
2) I have got 'Run with the highest privileges' selected
3) The error
4) The script

Performing database operations using EJB 3.0

I need to create a session bean that will perform operations on backend database. I am new to EJB 3.0 and need a gentle guidance to the solution
This is what I believe is suppose to be done
1. Create stateless bean interface marking operations.
2. Create bean implementation for above
3. Init stage will require me to connect to the Oracle database. Now am confused how will it get the connection details? Is there a way to extract the url username and password using resource bendle which can be accessed from within bean implementation?
4. Bean method will perform update, read oprations
5. Predestroy will close the connection
6. A client will simply call this ejb with some input parameter(s)
Please let me know if am doing anything wrong here

If you use EJB technology for which it is designed, the container (server) will manage the transaction (and also the connections to the database) for you, so no creation or cleanup of connections on your part. I advise you to read into JPA which is designed to be used in conjunction with EJB tech. The books Enterprise Javabeans 3.0 and Pro EJB 3: the Java Persistence API may help you a lot.

Database backup using RMAN

Hello All,
I am new to RMAN.
I am trying to make some backups of my database using enterprise manager, so i choose to backup my database based on the Oracle-Suggested Backup schedule.
I got the below command from EM:
Daily Script:
run {
allocate channel oem_disk_backup device type disk;
recover copy of database with tag 'ORA_OEM_LEVEL_0';
backup incremental level 1 cumulative copies=1 for recover of copy with tag 'ORA_OEM_LEVEL_0' database;
}i have the below question:
what does the above script do ? EM will create a job that will run it daily ? how can i check this job ? where is it logged?
where and how can i check the already configured channels ? for ex: channel oem_disk_backup
what does this script do ? recover copy of database with tag 'ORA_OEM_LEVEL_0' does it recover the database?
What are the RMAN scripts (run block), to backup my database once per week (for ex on Sunday)as level 0 backup and every day as incremental level 1 cumulative backup ? Since I think that the above script will run a level 0 backup once on the first execution and then the remaining backups are level 1 Incremental backups
Thanks and regards,

Database Backup using batch mode doesn't work

Hello,
i try to use the batch mode to backup the HANA DB (1.00.21) but nothing happens.
my backup.sql
\connect -n <server name> -i <instance number> -u <user> -p <password>
BACKUP DATA USING FILE ('Monday')
excecute the backup
/usr/sap/<SID>/HDB<instance number>/exe/hdbsql -I backup.sql
The instructions work for themselves but with this script nothing happens.
Any ideas?
Thanks

Hello,
The manual advises against your proposal rather, because the password is visible in the process.
Actually it is not advising against what I suggest and what it in the blog.
You have three options:
1.) run everything from command line (this is what SAP suggested that is wrong because you would see the password)
2.) store password in file - less wrong than option 1.) because everyone having access to file can see the password
3.) store password in encrypted user store and use just -U <user> (no password needed)
This is also suggested in guide:
In addition, the password must be saved in the hdbuserstore, and not in a file.
The issue is in separator - it is stated that default is '//' but apparently it is not - it is ';'.
This syntax would work:
\connect -n <server name> -i <instance number> -u <user> -p <password>;
BACKUP DATA USING FILE ('Monday');
Anyway - it is wrong from security perspective. User store is much better because the password is encrypted.

The purpose of taking the backup is, we are upgrading our oracle to 11.2.0.3 and We don't have any regular backups (RMAN or EXPORT) on these databases. these are QA databases.
Please let me know, how i need to prepare for this DB backup.
Thanks in advance for your help.

>

>
Why not? You can have expdp create multiple files on export so that each file is no larger than the size you specify. This makes it easier to manage large exports.
Using multiple files and a parallel export will handle this for you.
See the DUMPFILE section of the database utilities doc - http://docs.oracle.com/cd/B19306_01/server.102/b14215/dp_export.htm
It has this example of file splitting using PARALLEL
>
Example
The following is an example of using the DUMPFILE parameter:
expdp hr/hr SCHEMAS=hr DIRECTORY=dpump_dir1 DUMPFILE=dpump_dir2:exp1.dmp,exp2%U.dmp PARALLEL=3
The dump file, exp1.dmp, will be written to the path associated with the directory object dpump_dir2 because dpump_dir2 was specified as part of the dump file name, and therefore overrides the directory object specified with the DIRECTORY parameter. Because all three parallel processes will be given work to perform during this job, the exp201.dmp and exp202.dmp dump files will be created and they will be written to the path associated with the directory object, dpump_dir1, that was specified with the DIRECTORY parameter.

Why database backup information is not in rc_rman_status

Hi,
I used rman to backup dozen of databases. Only 3 database backup info is in rc_rman_status. I can see all databases fromrc_database. From EM console, every database target page shows the daily backup information. What happened?
I need to create a report for daily backups of all databases. I want to pull information directly from rc_rman_status. Any suggestions?
Thanks
Laura

Hello,
It is possible that your recovery catalog is 10g but you have performed a backup using a lower RMAN client such as 9i. I believe RC_RMAN_STATUS is a 10g addition and hence the 9i RMAN client will not populate these tables. Obviously I can't guarantee this is your problem, but if you have a mixed Oracle environment, this is a high possibility.
Hope that helps
Andy

Cold backup using RMAN

Dear All,
db_version :10.2.0.4
os_version:Window 2003 server
Environment:Test
I wish to perform cold backup using RMAN for the same i want to know following :
1. What is the script / command ?
2. How to restore cold backup completely ( ex:- if i lost all my data,redo and archives )
3. Is it mandatory to open the database in RESETLOG mode after recovery ( since i have a cold backup ) ?
Thanks in advance

A "Cold" Backup is called a "Consistent" Backup.
See http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup003.htm#sthref297
Backup :
From the RMAN command line :
SHUTDOWN IMMEDIATE
STARTUP MOUNT
BACKUP DATABASE
BACKUP CURRENT CONTROLFILE -- to get the controlfile in a separate backupsetRestore :
STARTUP MOUNT
RESTORE DATABASE
ALTER DATABASE OPENIf you use an SPFILE, you can have an SPFILE backup included automatically with the controlfile backupset with CONFIGURE CONTROLFILE AUTOBACKUP ON and CONFIGURE CONTROLFILE AUTOBACKUP FORMAT ...

Tnsname resolve failed after performing an restore using rman

I create an full database backup using rman and I want to perform an restore on another server. Steps are as follows.
1. Install the same release of oracle database and apply the same release of patches in the testing server.
2. Create an instance with the same name of original database.
3.Perform the restore using rman.
4.Create an spfile from pfile.
5.Add an new tempfile then delete the old one.
6. Shutdown the instance and restart it.
7. reconfigure the listner.
8. reconfigure the tns.
In this step it fails,saying that "TNS:listener does not currently know of service requested in connect descriptor",but if I change the servername to the original server name,it succeed.

SAP SQL 2008 Database Backup

Hi,
One of our client is taking the SAP SQL database backup using BRTOOL, backup happen on Standalone LTO 5.
They are taking backup of 1.4 TB in 1hr 30 Min.
I would like to know is it possible to achieve same as max write speed of LTO 5 in 140 MBPS, if we consider the are getting max throughput rate then too it should take around 3 hr 40 Min.
If it is possible then it would be grateful if someone can explain how.
Thanks & Regards
Mitt Gori

Hi Mitt,
You may refer the details shared under thread Full Database Backup in DB13 for MS SQL Server ... | SCN on configuration of backups using db13 for MSSQL.
What it comes to my mind is ..
1) Can you check whether you have SSDs configured for the database
2) What is the Tape write speed.
Note: SSD disks can drastically improve the backup times as it has excellent read/write performance over SAS disk.
Hope this helps.

Deepak Kori

Incremental Backup using "imsbackup"

Dear every body,
I have a trouble and need the help from you, please help me in this case if you can, thanks.
I want to backup incrementally my mailboxes with "imsbackup" command. I have tested following below example but not succeeded:
1. I send/receive email between 2 users in my domain at 08:00AM.
2. I performed FULL backup the whole message store using imsbackup
3. At 09:00AM I send/receive another email between 2 users in my domain
4. I performed INCREMENTAL backup the whole message store using "imsbackup -d 20091217:083000....." but my backup file including the messages that I sent before 08:30AM
I have done this several times and get the same result.
Please kindly help me in this case, how can I use imsbackup to incrementally backup my mailboxes.
Any help and advices from you is appreciated.
Thanks all of you so much.

Hi Shane,
Thanks so much for your response.
The version of Messaging Server I am using is:
{color:#ff0000}bash-3.00# ./imsimta version
Sun Java(tm) System Messaging Server 7.0-3.01 64bit (built Dec 9 2008){color}
For your question:
Does this problem occur if you incrementally back up a single mailbox e.g.
./imsbackup -d 20091217:083000 ... user/<uid>/
My Answer is:
I have not performed above step yet because I want to backup mailboxes of all users.
For your question:
Is the time/timezone set correctly on the server?
My answer is:
Yes, of courses. I already set time/timezone correctly. I also checked the time stamp of newly created email in message store in server, their date are correct.
For your question:
Are you in daylight savings time i.e. you shift the imsbackup incremental time back-forward an hour and get the correct result?
My answer is:
I already tried many times but got the same result. For example, At{color:#ff0000} 9AM Dec 16th 2009{color} I sent an email. At{color:#ff0000} 9AM one day later (Dec 17th 2009){color} I sent another email. I performed incremental backup using{color:#ff0000} "./imsbackup -d 20091216:120000 -f- / > /email_backup/incremental.120000".{color}
The backup file I got contained the email I sent at 9AM Dec 16th.
Any advice on this ?
Anyway, thanks so much for your help. I am awaiting your response.

After formatting and creating two partitions on my external HD, why is Time Machine taking 25x longer to perform a backup?

Hi.
I bought a macbookpro 13"retina, new two weeks ago and a G-tech 1TB external drive from the apple store. It's my first mac.
I performed a backup, using Time Machine, which copied 18 GB onto he 1TB external HD in around 20 minutes.
After a little more reading, I realised I should use Disk utility to partition the 1TB external G-tech drive into a 250gb partition, and a 750gb partition.
[My MBP has a 250gb flash HD. I'll use the other 750gb for storage of my other files, like photos, music etc.]
So, using disk utility I formatted the 1TB exernal drive, then created two partitions.
However, I've started backing up my data using time machine again, onto the 250gb partition, on the external drive, and its now taking 5 hours to copy the 19.81GB
So why is it taking 25x longer than the first time I did it? [First time it took 20 minutes]
Thanks

Since performing the fist backup, a couple of days ago, which took twenty minutes, and the second backup, which is taking 5 hours, I installed MS office for Mac 2011 and Silverlight.
Dont know if thats responsible?

Full db backup using expdp

Hi All,
My database version is 10.2.0.2 & I want to take full database backup using expdp.
This is the parfile I use.
userid=system/manager
full=y
directory=exp_dmp
parallel=4
The database size is 45 gb & the expdp dumpfile size comes to around 31gb. What can be done to compress the expdp dumpfile?
or is there some other parameters which i need to use?
thanks

I agree expdp is logical backup.
In 10g compression=metadata_only is the only option that can be used, so that does not help to compress the backup.
due to size restrictions, i want the dumpfile to be compressed as and when the backup is running, how to achieve this?
