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.

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.
regards

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
imp JISPREPCORBILLINGPRD501/JISPREPCORBILLINGPRD501 file=JISPREPCORBILLINGPRD501 fromuser=JISPREPCORBILLINGPRD501 touser=JISPREPCORBILLINGPRD501 grants=y constraints=Y rows=y log=JISPREPCORBILLINGPRD501_imp.log
Do, we need to drop the existing schema before importing or somethinig else. Please, help.
regards

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,

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:

regards

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.

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.

Tablespace Restore From Whole Database Backup

Hi
I tooks whole database backup.
BACKUP DATABASE;
Note:- No saperate tablespaces backup.
After that, if required I use to restore saprate tablespace from above backup.
RESTORE TABLESPACE tb_1;
RECOVER TABLESPACE tb_1;
Is this tecnique recomanded or not?

Jawad

There's no need to recover the whole database, if only one component has a failure. Tablespace recovery will only work, if the database runs in archivelog mode.

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,

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.

[Forum FAQ] How do I restore the CDC enabled database backups (FULL + DIFF) while maintaining the CDC integrity

Question
Background: When restoring Full + DIFF backups of a Change Data Capture (CDC) enabled database to a different SQL server, the CDC integrity is not being maintained. We did RESTORE the databases with the KEEP_CDC option.
How do I successfully restore the CDC enabled database backups (FULL + DIFF) while maintaining the CDC integrity?
Answer
When restoring a CDC enabled database on a different machine that is running SQL Server, besides using use the KEEP_CDC option to retain all the CDC metadata, you also need to add Capture and Cleanup jobs.
In addition, as you want to restore FULL + DIFF backups of a CDC enabled database, you need to note that the KEEP_CDC and NoRecovery options are incompatible. Use the KEEP_CDC option only when you are completing the recovery. I made a test to display
the whole process that how to restore the CDC enabled database backups (FULL + DIFF) on a different machine.

Question
Background: When restoring Full + DIFF backups of a Change Data Capture (CDC) enabled database to a different SQL server, the CDC integrity is not being maintained. We did RESTORE the databases with the KEEP_CDC option.
How do I successfully restore the CDC enabled database backups (FULL + DIFF) while maintaining the CDC integrity?
Answer
When restoring a CDC enabled database on a different machine that is running SQL Server, besides using use the KEEP_CDC option to retain all the CDC metadata, you also need to add Capture and Cleanup jobs.
In addition, as you want to restore FULL + DIFF backups of a CDC enabled database, you need to note that the KEEP_CDC and NoRecovery options are incompatible. Use the KEEP_CDC option only when you are completing the recovery. I made a test to display
the whole process that how to restore the CDC enabled database backups (FULL + DIFF) on a different machine.
Create a database named ’CDCTest’ in SQL Server 2012, then enable the CDC feature and take full+ differential backups of the database.
-- Create database CDCTest
CREATE DATABASE [CDCTest] ON PRIMARY
( NAME = N'CDCTest ', FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\ CDCTest.mdf' , SIZE = 5120KB ,
MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )
LOG ON
( NAME = N'CDCTest _log', FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\ CDCTest _log.LDF' , SIZE = 3840KB ,
MAXSIZE = 2048GB , FILEGROWTH = 10%)
GO
use CDCTest;
go

Undo tablespace currupt and no clean backup

Hello,
We are facing critical problem with database. We have not any clean backup and database in no archive log mode. Suddenly database is shutdown and when we are trying to open database it is giving error:-
ORA-01172: recovery of thread 1 stuck at block 350230 of file 3
ORA-01151: use media recovery to recover block, restore backup if needed
File 3 is Undo file.
Is there any way to open database?
Thanks in advance and please reply us ASAP.

1) First, follow Howardjr recomendations and allways do a backup first.
2) Open a SR with Metalink to help with your problem
3) If you want to try something here are some options, but never skip the point 1 previously explained.
Well, you have two possible scenarios, one supported other unsupported.
This is an inconsistency issue..
Solution
============
*1]Supported Solution:*
Restore-Incomplete recovery the DB from backup or rebuild the DB using an export dump.
*2]Internal (Not-supported) Solution:*
Update undo$ to change the status$ = 1 (undo segment is dropped) for the corrupted undo segment.
Caution:
This is NOT a supported solution. Therefore ensure that a full database cold backup is taken bbefore doing this data-dictionary patching.
Steps to do the patching:
1) First ensure that a full database backup is taken.
2) Modify/add the following parameters in initSID.ora:
undo_management=manual
job_queue_processes =0
aq_tm_processes=0
systemtrig_enabled=false
3) Shutdown
4) Startup restrict pfile
5) set transaction use rollback segment system;
if set transaction above fails, then not to proceed further.
6) Update undo$ to change the status$ = 1 (undo segment is dropped) for
the corrupt undo segment.
update undo$ set status$ = 1
where us# = <'undo segment id'>
and ts#=<'tablespace id'>
and file#=<'file id'>
and block# = <'block id'>
and status$=2;
or
update undo$ set status$ = 1
where name = <'corrupt undo segment name'>
and status$=2;
This will update only 1 row. Rollback the update if more than 1 row is updated.
7) Commit;
8) Shutdown abort
9) Set back in init.ora parameters modified in Step 2.
Startup restrict
10) Drop the corrupt undo tablespace using command:
drop tablespace <corrupt undo tablespace name> including contents;
11) Create new undo tablespace.
In initSID.ora, set undo_management=auto, undo_tablespace=<'new undo tablespace name'>
Restart the instance.
12) Take a backup.
*Parameter offlinerollback_segments is not useful:*
Trying to drop the corrupt undo segment or the undo tablespace by setting parameters undo management=manual and offline_rollback_segments in initSID.ora will fails with error: ORA-00600 [ktssdrp1].
To see the information about the corrupt block use this query:
select us#, name, ts#, file#, block#,status$ from undo$
where (ts#, file#, block#) not in
(select ts#, file#, block# from seg$ where type# in (1,10)) and status$ > 1;I had the same problem some time ago, and the unsupported solution works great, but never try it without a full backup first.
Cheers,
