9i to 10g Incremental Backup

I have an Oracle 9i database which I need to do incremental backup into my 10g database in the different server. What is the best way to do this?
any help would be greatly appreciated

I'm not sure I understand what you're after.
"Backup" generally means a physical backup-- RMAN or user managed backups. But that doesn't sound like what you're after. You don't restore physical backups into another database and the restored backup will always be the same Oracle version as the source database.
"Backup" might also refer to a logical backup taken via export (classic or DataPump). But you cannot (functionally and practically) generate an incremental export. You could import an export generated from a 9i database into a 10g database.
Perhaps you mean "replication" rather than "backup". If that is the case, can you explain the business problem you're trying to solve? There are a variety of ways to replicate data from one database to another-- Streams, materialized views, CDC, DataGuard, etc.-- depending on the problem you're trying to solve.

Optimized incremental backup in 10g

Hi,
I study the http://www.oracle.com/technology/products/database/oracle10g/pdf/twp_general_10gdb_product_family.pdf and i have one question about it...
In "Incremental backup" feature/option there is a note :"SE/XE no optimized incremental backup".
What are the features of "optimized incremental backup"...????
Thanks......
Sim

I believe that is referring to block change tracking. That allows Oracle to track which blocks have actually changed since the last backup, so RMAN can just read the tracking file and backup those blocks rather than examining each block to see whether it has changed.

How do I create an Oracle 10g offsite backup

Total size of the datafiles that make up the tablespaces of the DB = 1532121.6875 Mb
This size will eventually grow to about 6-7 terrabytes
I used the following query to determine the above size:
SELECT sum(bytes/1048576) FROM dba_extents; I saw this question poseted on another site
QUESTION POSED ON: 15 August 2007
I recently handled a project whereby we have many site servers at various places in our country and there is a central server in Delhi (India). My project is to take a backup of the local server and post that backup to the central server via Internet. I chose the RMAN (Recovery Manager) approach. Using that approach I can back up the database and connect to the remote database. But I can't find how to post the backup to the remote server. Please give me guidance regarding this project.
This was the answer:
EXPERT RESPONSE
Basically, there are two options to have RMAN back up to a remote server. One, back up locally and then FTP the backup to the remote server. Two, create a network file share from the database server to the remote server. Have RMAN back up to the network file share. It will think the file system is local, but in actuality, the file system is in another location.
Currently a level 1 incremental backup is done at 10:00PM every night to the array (this takes approximately 1 hour to be completed). I am interested in doing a full hot offsite backup of the DB to a disk on another server.
Can anyone tell me how would I be able to do this using RMAN and/or backing locally and then FTP'ing the backup to a remote sever.
Can anyone also confirm if the calculation for the size of the DB is accurate?
( I did the calculations based on what I saw at this site and this site)
I would like to do this in preperation for some firmware upgrade that our Sun support would like to do on the array, I would like to implement a script (or maybe use RMAN) to do a nightly offsite backup. I would still need to do the DB backup to the array...but what files do I copy off the array (to the remote server) for an offsite backup of the DB.
I would really appreciate any help.

Thanks for the help, I took a look at the script. Suppose however I didn't/couldn't do any modification of the Oracle RMAN settings (without voiding my support contract). Could I simply copy the necessary DB files to a remote server, would I be able to do a restore (if necessary) from those copied files?
Like I have pointed out before, currently an incremental level 1 backup (to the array) is done nightly at 10 (and it takes approximately 1 hour)

About incremental backup

Dear Friends ,
We have a ORacle 10g database server which is 24x7 hours running . We take everyday RMAN full backup ,now we want to run "Incremental rman backup" 6 days in a week and "Full Backup" rest of the week . But in oracle article we read that
"RMAN can only create incremental backups of datafiles, not of archived redo log files or other files."
(source: http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup001.htm#BRBSC131)
In this moment I think , archivelog is very important for database recovery and it is necessary to take archivelog backup regularly .Now if we want to run Incremental backup then I think I cannot take "archivelog" backup using following script :
run
allocate channel t1 type 'sbt_tape' parms
'ENV=(TDPO_OPTFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.opt)';
sql "alter system switch logfile";
backup incremental level 1 database plus archivelog;
Give me some idea plz ... ...what should I need to ?

Sorry Hemant ,
Accroding to ur advice , I run the script following way :
run
allocate channel t1 type disk;
backup incremental level 1 database;
sql "alter system switch logfile";
backup archivelog;
But I got the following ERROR :
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================

RMAN>
But when I use the following script , it shows no error :
run
allocate channel t1 type disk;
sql "alter system switch logfile";
backup incremental level 1 database plus archivelog;
I think here database is backup only using LEVEL 1 , but archivelog is backed up full . Here is the output :

3> allocate channel t1 type disk;
4> sql "alter system switch logfile";
5> backup incremental level 1 database plus archivelog;

Incremental BACKUP to resolve large gap in Data Guard

Hi, all,
We run into a situation that standby database was shutdown for a long time and had a large gap between the primary and standby. I am interested in the idea to use incremental backup from primary db to resolve the gap. Does anyone know the procedure to do the work? Our environment is Oracle 10g RAC R2 on both primary and standby, ASM. Any suggestions are highly appreciated. Thanks in advance

Is Fast Incremental Backups possible on standby databases for 10.2.0.5?

Hi,
Can anyone help to clarify if it is possible to have Fast Incremental Backups on 10.2.0.5 standby . The information in MOS (Doc ID 262853.1) stated:
Note : Fast Incremental Backups were not possible on standby databases till 10g
but from 11g Fast Incremental Backups are available on standby databases also.
It sounds ambiguous.
Thanks

The answer is No, due bug 6130588.

Oracle incremental backup too slow

Hello All,
Oracle 9.2.0.7
Windows 2003 server
Database size around 200 GB.
Daily archive generation may be around 40. Archive log size 200 MB.
We have implemented the below backup strategy
1. weekly once full incremental level 0 backup(differential).
2. Daily incremental level 1 backup(differential).
Daily incremental backup size will be around 1 GB.
Now we are facing a problem because of the incremental backup. The incremental backup is taking more than 1 hour time to complete. So we are not able to run it in the production time.its a 24/7 production database.
Please advice how to reduce the incremental backup time ?
Is there any options like what we have in 10g Block change tracking. please advice..
TIA,

Restoring Incremental Backup using Netbackup

Hi,
Need your help. We have a backup of our Oracle 10g Database(one full backup and one incremental backup). The full backup (level0) is done by Netbackup and the incremental backup is done by local rman.
Now we want to restore the database. I have modified the script of Netbackup to restore the controlfile of incremental backup and allocate 2 channels for tape and disk. Our incremental backup resides in disk. Is the script we used below correct?
RUN {
ALLOCATE CHANNEL ch00 TYPE DISK;
send 'NB_ORA_CLIENT=prod01, NB_ORA_SERV=NAS';
RESTORE CONTROLFILE FROM '/rman/backup/incremental/ctl_PROD_c-86955024-20101221-
03';
ALTER DATABASE MOUNT;
RELEASE CHANNEL ch00;
RUN {
ALLOCATE CHANNEL ch00 TYPE 'SBT_TAPE';
ALLOCATE CHANNEL ch01 TYPE DISK;
send 'NB_ORA_CLIENT=prod01, NB_ORA_SERV=NAS';
#SET UNTIL SEQUENCE 138730 thread 1;
RESTORE DATABASE;
RECOVER DATABASE;
RELEASE CHANNEL ch00;
RELEASE CHANNEL ch01;
thanks,
Benjo

Hi benjo,
You cannot allocate two types of channels at the same time so you should try a three step approach.
(Every time create a new connection to the target.)
Restore controlfile
No need for:
send 'NB_ORA_CLIENT=prod01, NB_ORA_SERV=NAS';exit
Restore database from tape.
remove from your second run block
ALLOCATE CHANNEL ch01 TYPE DISK;
RECOVER DATABASE;
RELEASE CHANNEL ch01;exit
Than create a recover command with disk channels
basicly remove the tape channel and restore commands from your second run block and add
alter database open resetlogs;Regards,
Tycho

Incremental Backup Levels

Hello Everybody.
I want to know the description of all 0-4 levels of incremental backups. Anybody please tell me in details.
Thanks and Regards

ora-boy
Questions like this have version specific answers. Almost all questions have.
It is useless and silly to post any question without any version information.
Here's why
In 8i and 9i: incremental levels are between 0 and 3. There is nothing to explain,
1>0, 2>1, 3>2. That's all.
In 10g there is only 0 and 1. The higher levels have been removed.
Please stop asking questions without version information, assuming people keep track of your version (which we don't) or will summarize it for all available versions (which we won't )

Question about using an incremental backup to update a standby

We have a 2TB Oracle 10g database with a standby and the application that uses it is about to be updated. We're using cumulative incremental backups with block change tracking to back it up with weekly level 0 backups. The application upgrade will be making a lot of changes (several hundred GB) and we have stop the standby during the upgrade process as a quick way to get back (we don't have the space for a flashback recovery) in the event that there are issues with the upgrade. We can just let the archivelogs back up and get them over to the standby and applied once they decide they like the upgrade but, it looks like it would be simpler and perhaps quicker to use an incremental backup to update the standby. I probably won't but, If we do that, it looks like we can turn off archivelogs in the primary and not deal with them at all. I've never tried this but, I do have some questions.
Does it make sense to take this approach?
If we were to turn off archivelogs in the primary, would that have any effect on block change tracking? I don't see why it would but, had to ask. Of course, we would turn archivelogs back on and take a level 1 backup after the upgrade.
Thanks in advance for the education.

Funny you should mention that rolling upgrade, I'm actually planning to do that in another environment. My testing says it works pretty well and I'll be able to move a 400GB database to new hardware and upgrade it to 11g with very little downtime. However, in this case, the database is not being upgraded. The application is. It's just that, as part of that upgrade, there are a lot of updates and I'd just as soon not deal with the archivelogs for that. Here's what I was thinking about:
Set logs shipping to defer in the primary.
Stop log apply in the standby.
Turn off archivelogs in the primary.
Do the application update.
If they like the results, turn archivelogs back on in the primary.
Take an rman incremental backup from scn in the primary.
Apply the incremental backup to the standby.
Start log log apply in the standby.
Start log shipping in the primary.
The process for getting and using the incremental is described here:
http://docs.oracle.com/cd/B19306_01/backup.102/b14191/rcmdupdb.htm#BGBCEBJG
This isn't your regular incremental backup.
So, am I the only crazy one? Has anyone else tried this?

Incremental backup Doubt!

hi,
Oracle version:10.2.0.1.0
In 10G is there any way to merge the incremental backup into a fullbackup?
I read it here
"Incremental backups are merged into the online full
image backup thereby creating a new full backup current
to the point of the merged incremental "
if yes. how ?plz explain...
TIA,

This particular syntax only applied to image copies.
Backups have always been "refreshable" with incrementals by virtue of simply doing 'recover database': if it thinks it appropriate, RMAN has always been able to take block images from a later incremental and 'slot it in' to the base backup to effectively bring it more up to date. Then, redo is applied to bring it completely up to date.
The new syntax available in 10g was designed to allow the same sort of 'refresh' capability to image copies which had previously lacked them and which could therefore previously only be brought up to date by applying redo to them. If you image copies were taken only once a week (say), and your database crashed on the 6th day, that could be a very slow recovery (lots of redo takes a long time to apply). If you can take your Sunday image copy and slot in blocks copied during a Wednesday backup, you effectively have a Wednesday image copy. So a recovery done by applying redo to it on the Friday will have much less work to do.

RMAN weekly full backup and daily incremental backup script.

Hallo! I would like to implement an Oracle 10g database backup policy where every Sunday night at 10 pm, a hot full compressed database backup is done, for every other day i.e. Monday to Saturday, a daily incremental compressed backup is done also at 10 pm.
If anyone as an RMAN script that can perform such a backup, please provide me with it.
Thanks.

Use DBMS_SCHEDULER or cron job (I hope you're using Linux) to create a schedule which invokes rman script to take backup you want
Try it and we'll help you
