Doubt between RMAN and User Managed Backup

Friends,
OS: RHEL AS 3.0
DB: 9iR2
Currently we are taking user managed backup.
rman is in testing(learning) process.
Is it possible to take rman backup and user managed backup of a database one after another?
what i mean is.....suppose, if we configure rman for auto backup at 9pm daily. can i take user managed backup before 8pm or after 10pm?
Am i have to take any precaution's?
suppose, rman is failed can i restore the db with user managed backup?
thanks

Yes, it is possible to perform both user managed backups and RMAN backups.
It is a waste of resources, but it is possible.
You would need to make sure both backups do not overlap each other.
Whether you can restore your database with user managed backup depends completely on the quality of the user managed backup, and whether you have proper (and tested) restore procedures in place.

DB Taken out of Backup Mode During User-Managed Backup

I was taking a user-managed backup and the DB was accidentally taken out of backup mode in the middle of the backup. The backup continued and backed up all the datafiles, but many of the datafiles were backed up after backup mode was turned off. Can I restore the DB using this backup? What are my options?

The backup might be usable and it might not. When you put a tablespace (actually all data files in the tablespace) into backup mode, Oracle continues to perform writes to those data files. However, when first modifying a block in a data file after it has been put in backup mode, Oracle will put a before image of that entire block in the redo log (instead of just the row changes). After this first data block change is written to the redo log, further changes to this data block are written as just normal. Oracle does this initial write of the whole block to prevent fractured blocks during recovery. You see, when the OS copies the files for backup, it copies in chunks that might, or might not, fall on a data block boundary. A data block may be updated on disk between two OS file copy chunks. Thus when the file is restored it is possible that part of a data block will have new data and another part have old. This is a fractured block. When applying undo, Oracle first lays down a full block, which will cure a possible fractured block, and then apply redo as normal to complete the recovery operation.
This is why it is important to make sure that your hot backup set includes all redo generated between the time you put the tablespaces in backup mode and the time you took them out of backup mode.

Dv6775us HP Backup and Recovery Manager software corrupted - can't find download

I am getting an HP error message saying the HP Backup and Recovery Manager software has been corrupted and needs to be updated. For over an hour I have been frustrated trying to find where on this site to download a replacement of what was installed or an upgrade that would repair the problem.
Can anyone point me to where I can get the software? Thanks.
HP Pavilion dv6775us
Vista Home Advanced

Did you make a recovery disk set or usb recovery media?
If you did, then you are in luck because that is the software that can be used to reinstall the Recovery manager.
The downside is that you will have to do a factory image recovery to reinstall the software. A recovery is a destructive process, unlike a Windows stystem restore. A recovery will mean that you will needto save all of your data externally to avoid losing it and reinstall all of your programs after the recovery is complete.

HP Backup and Recovery Manager for Windows 7

I installed all the softwares and drivers that came along with the HP upgrade DVD. But, I find that the Backup and Recovery Manager missing on the DVD. Is there a Backup and Recovery Manager for Win 7? I liked the backup and recovery manager that was available on my Vista when I bought this laptop but is now unavailable because of the upgrade!! Any solutions for this? I do not want to use the default Windows Backup as I do not have a separate HDD at the moment to store the backup there and do not wish to populate my local hard disk with backup data!! Thanks.
This question was solved.
View Solution.

Yea, basically. There's no working program for your laptop so it seems that you can use from within Windows 7.
However, if you have problems, recovery discs will work. As well, if your recovery partition still exists, you can still access it by pressing F11 when you see the HP logo at startup.

Is User-managed Backup&Recovery Useless Because of RMAN?

Is user-managed backup&recovery method useless because of RMAN?

Nice dicussion!
Also, one has to remember that if your database is using ASM, RMAN is the only option for backup/restore/recover (atleast in 10g).
Can SAN Snapshot/SplitMirroring be used to take a backup of database using ASM?

Droping and renaming tablespace druing hot user managed backup

Will dropping and renaming of tablespace will have any effect if hot user managed backup of that db is in progress ?
thanks in advance

However, you will encounter a more serious issue because of the way DROP TABLESPACE works.
Even if the DROP fails, the "INCLUDING CONTENTS" causes all segments to be dropped !!
SQL> drop table ASSM_TABLE purge;
Table dropped.
SQL> create table ASSM_TABLE (pk_col number not null, descr_col varchar2(30)) tablespace ASSM_TBS;
Table created.
SQL> create unique index ASSM_TABLE_PK on ASSM_TABLE (pk_col) tablespace ASSM_TBS;
Index created.
SQL> select segment_name, segment_type from user_segments where tablespace_name = 'ASSM_TBS';
SEGMENT_NAME                   SEGMENT_TYPE
ASSM_TABLE_PK                  INDEX
ASSM_TABLE                     TABLE
SQL> insert into ASSM_TABLE select rownum, 'ABCD ' || rownum from dual connect by level < 10;
9 rows created.
SQL> commit;
Commit complete.
SQL>
SQL> connect / as sysdba
Connected.
SQL>
SQL> alter tablespace ASSM_TBS begin backup;
Tablespace altered.
SQL> drop tablespace ASSM_TBS including contents and datafiles;
drop tablespace ASSM_TBS including contents and datafiles
ERROR at line 1:
ORA-01150: cannot prevent writes - file 7 has online backup set
ORA-01110: data file 7:

SQL> connect hemant/hemant
Connected.
SQL> select segment_name, segment_type from user_segments where tablespace_name = 'ASSM_TBS';
no rows selected
SQL> alter tablespace ASSM_TBS end backup

Tablespace altered.
SQL>The DROP TABLESPACE failed but the contents did get dropped !

Oracle Backup and Recovery 101: where can I get more information?

Hey everyone. I'm a pretty new Oracle DBA and backup and recovery is something I want to learn as much about as I can.
I read a blog about "how to be a good DBA" and it really drove home the importance of backups. I know how important they are, I just want to learn more.
What I mean is, I understand a lot of the high level concepts. It is pretty much straight forward. What I am looking for is something that really goes down in the internals of what is going on behind the scenes so I know what is going on.
I thought it would be extremely beneficial for me to learn about user backups. Granted, RMAN is the direction my company is heading to, but right now, we are doing user made backups. My thinking is that if I can get a solid grip and understanding of backup and recovery, user made backups, it will make the transition to RMAN much easier. That way, when I am working in RMAN, issue a command to do backup, I know the equivalent of a user backup and what is going on.
I hope that makes sense.
Is there a recommended book that goes over backup and recovery in depth?
I'd like to learn about all the user-made backup commands that can be executed at the command line (example, putting a tablespace in backup).
Since backups are essential to the life of a DBA, I thought the more I know, the better off I would be.

You can always find good information from Oracle document site,
Oracle® Database Backup and Recovery Basics
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/toc.htm
Oracle® Database Backup and Recovery Advanced User's Guide
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14191/toc.htm
User managed backup is quite different from RMAN backup. For RMAN backup you need to get familiar with the RMAN command syntax and configure.

User-managed backups of a 10g DB using ASM

Is it possible to do user-managed backups of a 10g database which is using ASM?
When I run the following SQL command
SELECT NAME FROM v$datafile;
It returns
+DBDATA/db_test/datafile/system.256.617633575
+DBDATA/db_test/datafile/users.259.617633757
The ASM is setup in 'normal redundency' across 2 partitions, both of which are not formatted.
If there is anyone who has done user-mangaged backups on a 10g DB using ASM who could provide an insight I would be greatful.
Basically what I would like to know is how do I access the datafiles, so I can back them up to a location of my choosing?

I think it's a good product, we use it for many years now. A big advantage is Backtrack automates not only backups (that do all products), it also provides automatic restore/recovery in many cases (not in all!). That means the product detects what is wrong with the database and automatically performs all necessary steps to bring back the database to working. In case of trouble that's good for operators by night and also good for the DBA, who does not need to come.
Disadvantage (may be true for all 3rd party products) Backtrack is always behind Oracle's newest technology, so it took some time to support ASM and it's still not a full support.
There's no problem with online backups, Backtrack uses the traditional way (ALTER TABLESPACE BEGIN BACKUP .... END BACKUP), they don't use RMAN technology in the background.
We use both in our company, Backtrack and RMAN. Besides the technical point of view, there's also a license issue. Backtrack's license fee is due to amount of data, the larger your databases the larger the fee.

User managed backup

I am a newbie to Oracle. I am having a question regarding user managed hot backup. My oracle version is 11.2.0.2 and OS version is OEL.
What will happen, if we perform User Managed Hot Backup without setting tablespaces in BEGIN BACKUP mode?

The bigger question is why you would do a user managed backup in the first place. User managed backup means user managed recovery. The oracle supplied utility for database backup is 'rman', and the 'r' stand for 'recovery' -- as in "Recovery Manager". Not using rman to do your backups is akin to not using the spare tire, jack, and lug wrench that came with your car to fix a flat tire.
============================================================================
BTW, it would be really helpful if you would go to your profile and give yourself a recognizable name. It doesn't have to be your real name, just something that looks like a real name. Who says my name is really Ed Stevens? But at least when people see that on a message they have a known identity. Unlike the system generated name of 'ed0f625b-6857-4956-9b66-da280b7cf3a2', which is like going to the pub with a bag over your head.
