Command - Take a full database backup

Hi,
I have to simulate a database failure. However prior to doing so, I have to take a "Take a full database backup". How do I execute this command? It is my understanding that this is different from selecting "Backup database"
Thanks in advance for the help!

This channel can be allocated manually or can be pre-configured by using
automatic channel allocation.
The number of allocated channels determines the maximum degree of
parallelism that is used during backup restore or recovery. For example if
you allocate 8 channels for a backup operation 8 background processes for the
operation can run concurrently.
Parallelism of backup sets allocates multiple channels and assigns
files to specific channels. You can configure parallel backups by setting a
PARALLELISM option of the CONFIGURE command to a value greater than 1 or by
manually allocating multiple channels.

Full database backup and restore

I have a doubt on the syntax for a full database backup and restore. For a single schema, the syntax for backup & restore is :-
exp JISPREPCORBILLINGPRD501/JISPREPCORBILLINGPRD501 owner=JISPREPCORBILLINGPRD501 STATISTICS=none
log=JISPREPCORBILLINGPRD501_exp.log grants=y constraints=Y rows=y compress=N
file=JISPREPCORBILLINGPRD501
imp <userid/password> file=<export dump file location> fromuser=<export user name> touser=<import user name>
grants=y constraints=Y rows=y log=<import log file location>
I hope, my question is clear.
Please, help in solving the doubt.

hi,
thanks, for your answer. I took a export of one schema of the database. But, when I tried to import the schema to the destination database, it showed
imported with errors with the existence of functions showing. The commands used by me for export and import are as follows:-
exp JISPREPCORBILLINGPRD501/JISPREPCORBILLINGPRD501 owner=JISPREPCORBILLINGPRD501 STATISTICS=none log=JISPREPCORBILLINGPRD501_exp.log grants=y constraints=Y rows=y compress=N file=JISPREPCORBILLINGPRD501

Do, we need to drop the existing schema before importing or somethinig else. Please, help.

Full Database Backup

Hi people,
I´ve the next doubt about the backups of MS SQL Server.
If I make a full database backup, the transaction log (SIDLOG1) are backed? Or I´ve to do the backup of transactional log separated?
In the note Note 44449 - Backup strategies with the SQL server, says this:
"If you run a complete database backup, the contents of the transaction log are saved (database dump), but the log is not shortened. The transaction log is only shortened when you save the log (transaction dump)."

A FULL SQL backup includes all of the changes that are contained in the LOG file, so that the backup is recoverable to any point in time from the beginning to the end of the time it takes to backup the database. However, it does NOT truncate the log file because you may still need a log backup in order to be recoverable to a point in time AFTER the FULL backup mentioned earlier, or if you have to utilize a different FULL backup in the event the other backup is corrupted, lost, etc.
For example:
Full backup A taken 11/8/2010, begin 8:00 AM, completed 9:00 AM.
Transaction Log backup 1 taken 11/8/2010, 11:00 AM
Transaction Log backup 2 taken 11/8/2010, 3:00 PM
Transaction Log backup 3 taken 11/8/2010, 7:00 PM
Full backup B taken 11/9/2010, begin 8:00 AM, completed 9:00 AM.
Transaction Log backup 4 taken 11/9/2010, 11:00 AM
Transaction Log backup 5 taken 11/9/2010, 3:00 PM
Transaction Log backup 6 taken 11/9/2010, 7:00 PM
If you need to recover to point in time 11/9/2010 at 8:30 AM, all you need is Full backup B.
If you need to recover to point in time 11/9/2010 at 5:00 PM, you need Full backup B, and Transaction Logs 4, 5, and 6.
If you need to recover to point in time 11/9/2010 at 5:00 PM, and Full backup B is corrupted, you need Full backup A, and Transaction Logs 1, 2, 3, 4, 5, and 6.
If Full backup B had truncated the log, then you would not be recoverable to any point in time after 7:00 PM on 11/8/2010.

Full Database Backup in DB13 for MS SQL Server databases

Hello,
We have some SAP systems using the MS SQL Server database. I want to know if it is possible to setup the Full Database Backup option in transaction DB13 to store the files in a hard disk space.
I already did this type of configuration in SAP systems in Oracle databases and for this I used the init<SID>.sap where we can put all the configuration, for instance the disk path where we want to save the backup files! But for MS SQL Server databases, in DB13, I don´t know how to do that, when I add the "Full Database Backup" option in DB13, this show me some options but only for tape, but I don´t want to store the backup files in tapes, I want to store/save the files on the server disk itself or else to an external disk but I don´t see where I can set this way of storage!
This is what you see in DB13 (when using a MS SQL Server database) in "Full Database Backup" and as you see I only have options for TAPE not for a disk or other type of storage! How can I do that? (if that is possible):
Can you help me please?
Kind regards,
samid raif

Hello Raja
Sorry for the delay of my answer! Many thanks for that tip, it helps a lot and it solve the last error/problem that I reported here, in fact, the problem was we had named the device with two words containing a space. So we removed that space from the backup device (in SQL management studio) with one word only and the job runs successfully without any errors!
It works in Development and Quality systems but in our Production system (AM1) the Full backup option in DB13 stopped with the following error, in fact the error is on verification of backup, it means that the Full backup finished with success, but when it does the backup verification, the job in DB13 stops with an error, the following one:

Urgent -- need to restore table from full database backup

Hello,
Can somebody tell me the process for restoring just a table from a full database backup?
I did a full online database backup yesterday, and one of my tables got ruined today. I need to restore it as soon as possible, but I don't know how. When I tried flashback tables, it said that feature wasn't enabled. Should I restore the datafile or the tablespace?
Thanks much,
Nora

If you only want to recover the table and not the other objects in the tablespace, and assuming the table was damaged by a user statement (and not, say, block corruption), you would need to recover your backup to a different system, export the table that was damaged, and import the table into your real production database. If you can recover the entire tablespace to an earlier point in time, or if you can lose some committed changes to other database objects, you may have other options.

            1) First of all I gone to /oracle/<SID>/102_64/dbs/init<SID>.sap and I changed the settings backup_dev_type = disk
             backup_root_dir = /home/db0/test/sateesh/DB0backup
             stage_root_dir = /home/db0/test/sateesh/DB0backup

Restore a single table from full database backup

Hi,
I have a full database (10.2.0.1) backup with RMAN.
Suddenly a table got truncated. How to get back that table without restoring and recovering the full database (Point in time recovery) since if I restore the database to an earlier time then the other transactions will hamper.
Also creating a standby database and import export the table will solve my problem. But is there any other way to restore the lost table.
Thanks in advance.

No other way to restore the data if you don't want do point in time recovery. If you drop the table then you can restore it from the recyclebin but for the truncate operation it won't help. If you have enabled the flash back table for that particular table then you can restore the data for only that table.

Estimating the backup size for full database backup?

How to estimate the backup file size for the following backup command?
Oracle 10g R2 on HPUX
BACKUP INCREMENTAL LEVEL 0 DATABASE;
Thank you,
Smith

Depends on the number of used blocks, block size etc. You could probably get a rough formula for backup size based on the contents of dba_tab_statistics (subtract empty_blocks), dba_ind_statistics etc.

Need to take SQL Azure database backup into blob using dacpac services, the blob has to be encrypted.

We are able to take backup of our database into blob storage using dacpac services, but we need to encrypt the blob data. Please suggest the efficient way to do it.

Hello,
As per my understanding, Windows Azure Storage does not transparently encrypt data or provide any special encryption mechanisms. Azure Blob Storage protect the data by using a storage key to control access to all data in that Storage Account.
If you want to encrypt data of file inside Azure Blob Storage Services , you can refer to the following thread about same requirement:

Java code to take database backup

Hi,
I need java code which can take Ms.access database backup on 15th of every month. Please help me to do that.
Advance thanks

make a batch file to copy the little db from it's location to the backup location or invoke the backup command with the correct commandline parameters so you do not get prompted for input, go into the Windoz scheduler and tell it to run the batchfile on the 15th of ever month. Doing this with a language is going to be a problem in logistics you do not have to deal with.

Is it possible to take a full backup without shutting down an instance?(10g

Hi. everyone.
Is it possible to take a full backup without shutting down an instance?
The db version is 10gr2.
As far as I know, in order to take a full backup of a database,
one need to shutdown a database.
Our db environment is a RAC environment which has two nodes.
Yesterday, I heard from a hardware vendor that we do not need to shutdown
instances(2-nodes) in order to take a full backup.
Best Regards.

Hi,
>>As far as I know, in order to take a full backup of a database, one need to shutdown a database.
In fact, a database operating in NOARCHIVELOG mode is necessary to shutdown the database in order to perform a full backup (Cold Backup), but otherwise a database that is operating in ARCHIVELOG mode, then is possible to perform a full database backup with the database in a open state. (Hot Backup)
