Hi,
I need to learn RMAN in which I don't know the basics. So can some body please let me know any book or material to learn basics of RMAN ?
Thanks

Trying to learn RMAN

I'm trying to learn RMAN, so I tried the following test:
rman
Connect Target;
shutdown immediate;
startup mount;
backup database;
Then I deleted all the tables in the SCOTT schema and did this:
rman
STARTUP FORCE MOUNT;
RESTORE DATABASE;
RECOVER DATABASE;
ALTER DATABASE OPEN;
After restoration, everything in the SCOTT schema was still gone.
Any ideas why restoration did not seem to work?

First of all this backup is for media failure, if you drop some tables then you dont need to restore the whole backups.
In your case what you did is:
First took the backup which was having those scott tables
Then you delete the tables but the whole stuff was still there in redo files
Then you restore and recover the database and oracle applied all the available redo on database which contains your delete statements too and thats why you are not getting those tables back. And thats the reason why you are able to open the database using "ALTER DATABASE OPEN" statement.
Try running "alter system switch logfile" command around 5-6 times after dropping tables and then try to restore and recover and see what happen. Also from now onwards start reading this:

RMAN script for hot backup (looking for code critic) code attached.

Hello Guru's,
I have been having soem trouble running a successful hot full rman backup nightly.
We max our CPU load whenever our RMAN takes too long and conflicts with a Legato tape backup. I have a development server that I attempted to get a consistent backup time duration that is rock solid as to not conflict with the Legato backup time.
I just found out about duration with RMAN scripts here is my code:
#!/bin/bash
#rman backup script for daily hot whole database backup
at -f /hd1/rman_scripts/rman_backup 0600 tomorrow
rman target/
run {
allocate channel d1 device type disk format '/path/%U';
backup duration 1:00 partial minimize load database filesperset 1;
backup as BACKUPSET tag '%TAG' database;
backup as BACKUPSET tag '%TAG' archivelog all delete all input;
delete noprompt obsolete;
release channel d1;
exit
It completes the backup, but does not use the 1 hour allocated- it only uses 15 minutes on average and creates many files instead of normally three backup files.
Here is the results from querying the v$rman_status table for operation,status,start_time:
RMAN,FAILED, 17-OCT-06 0600
BACKUP,FAILED,17-OCT-06 0600
RMAN,FAILED,17-OCT-06 0606
BACKUP,COMPLETED,17-OCT-06 0606
BACKUP,COMPLETED,17-OCT-06 0606
BACKUP,FAILED,17-OCT-06 0615
RMAN,COMPLETED,17-OCT-06 1513
REPORT,COMPLETED,17-OCT-06 1513
DELETE,COMPLETED,17-OCT-06 1513
However, the timestamps of the backupset files it creates is:
06:15 and not 1513?????????????
RMAN appears to have only taken 15 minutes to create the files, why do I have a completed timestamp from v$rman_status of 1513???
Please advise and comment, I am just learning RMAN.

Try to remove the DURATION option in your script.
Here more details about that part.

Rman - rolling foward with archive logs during recovery

Database: 9.2.0.6; OS Windows 2003, Rman Backups performed through OEM 10g.
I have been a long time "write your own scripts" for backups but now I'm learning rman. Purchased the Oracle Database 10g RMAN Backup and Recovery book, but it doesn't have all the answers.
I have previously recovered a database using my "scripts" and rolled the database forward using archive files, but how is this done with rman? Rman seems to rely on the control file and backup pieces, where the scripts allowed me to just specify "recover database until cancel".
I have successfully recovered a database. It stopped once it could no longer find the next scn number. I then thought I could copy over the archive logs I have and try it again, try to roll forward, however, during the recover process there were two archive files created which were the next sequence, so I have dupes.
How do I perform a recover, and apply any archives which were not part of the rman backup?
The following is what I performed. I copied all my rman backup pieces to a new server. I created a clone of the directory structure,
oradim -new -sid <dbname>
orapwd file=<file_name> password=tiger
set oracle_sid=<dbname>
rman target /
startup force nomount
restore spfile from <file_name>
shutdown immediate
startup nomount
restore controlfile from <file_name>
restore database
-- NOTE: It ran and then stopped when it could no longer file the next log sequence
alter database reset logs;
The database opened and I can access it, but I really need to roll the logs forward.
thanks in advance.

If these are archive logs that RMAN doesn't know about, you'll need to CATALOG these archivelogs before RMAN can use them.

DB Backup with RMAN

Hi experts;
May be this question can be consider ingenuo, but I need to create a backup for a DB, but I'm learning RMAN, I know how to write a script in unix to create an export/import, but I don't know how to create a script to do a backup for the complete DB. The DB it's not in archive mode.
So, I need ideas how to write the script to backup the complete DB.
Can somebody help me with this?
Thanks and regards
ANG

Well, I was executing the followings commands, and this is what I got:
First in SQL;
SQL> connect /as sysdba
Connected.
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> STARTUP MOUNT;
ORACLE instance started.

Then, in RMAN after setting ORACLE_HOME and ORACLE_SID:
RMAN> backup database;

What I'm doing wrong?

How popular is RMAN

I've been working as a DBA supporting applications development. Now,i have decided to move to Production Side. Now i am preparing for interviews. Before i spend time learning RMAN, I just want to know whether it is worth learning RMAN coz It wasn't very popular back in 2005.
Corrected to popular

Hi,
>>Before i spend time learning RMAN, I just want to know whether it is worth learning RMAN coz It wasn't very popular back in 2005.
Of course it is ... In addition to Richards' post, I think that even though the user managed backup has been historically helpful in previous Oracle versions (7, 8 ...), I think that the current trend shows that not only most larger database sites, but also small and medium databases are using RMAN to conduct their backups. The reason for this is because of RMAN’s extended it capabilities (9i, 10g, 11g). However, either the OS backup or user managed backups can be still useful to the DBA (it depends of each Oracle environment). For me, had been performed user managed backups has been very useful to understand the physical backup/recovery fundamentals. In the same way, I believe that you can use RMAN also to train yourself so that you understand the physical backup fundamentals though. Well, my tip here is: after you have learned as much as you can from the user managed backup, move on to RMAN, in order to build on these fundamentals ... ;-)

Learning where to look things up in the documentation is time well spent investing in your career. To that end, you should drop everything else you are doing and do the following:
Go to tahiti.oracle.com. Drill down to your product and version.
Spend a few minutes just getting familiar with what is available here. Take special note of the "books" and "search" tabs. Under the "books" tab you will find the complete documentation library.
Spend a few minutes just getting familiar with what kind of documentation is available there by simply browsing the titles under the "Books" tab.
Open the Reference Manual and spend a few minutes looking through the table of contents to get familiar with what kind of information is available there.
Do the same with the SQL Reference Manual.
Do the same with the Utilities manual.
You don't have to read the above in depth. They are reference manuals. Just get familiar with what is there to be referenced. Ninety percent of the questions asked on this forum can be answered in less than 5 minutes by simply searching one of the above manuals.
Then set yourself a plan to dig deeper.
- Read a chapter a day from the Concepts Manual.
- Take a look in your alert log. One of the first things listed at startup is the initialization parms with non-default values. Read up on each one of them in the Reference Manual.
- Take a look at your listener.ora, tnsnames.ora, and sqlnet.ora files. Go to the Network Administrators manual and read up on everything you see in those files.
- When you have finished reading the Concepts Manual, do it again.
Give a man a fish and he eats for a day. Teach a man to fish and he eats for a lifetime.

RMAN Backup suggestion

Hi all,
I have migrated database from 8i to 10gr2.For Backup in 8i, we used a RMAN shell script (scheduled uding cron tab) to backup the database to Tape.(VERITAS BACKUP).
I am new to 10G.I checked out the options to backup the database using Oracle Enterprise manager DB console.
http://www.oracle.com/technology/obe/10gr2_db_single/ha/rman/rman_otn.htm#t1d
I am planning to take a test backup using the steps mentioned inthe above url.Could any one suggest whcih is the best option for database backup,eiether to use Oracle Enterprise manager DB console or thru RMAN shell script for backup..?

Unable to Restore Database

We are attempting to migrate from an older windows platform to a Windows 2008 platform. The old configuration had two disk drives, and Oracle Express was installed on E: - the new server, being virtual has been configured with only the C: drive.
I've been reading up on RMAN, and have confirmed that the daily backup process on the old server does create an RMAN backup.
I've installed (and several repeat uninstall/installs) a copy of Oracle Express 10g in the default location, accepting all defaults except for my password (which is irrelevant under RMAN).
I've duplicated the directories, I've figured out how to restart the database so I don't have to reinstall, but I am unable to restore the application database. I'm not eager to use other utilities than RMAN, since learning RMAN has already taken up more time than is budgeted for this task.
I receive varying error messages, depending on the techniques I try to use. Usually I receive this closing message:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of startup command at 12/14/2010 13:39:24
RMAN-04014: startup failed: ORA-02778: Name given for the log directory is invalid
The other message I receive is the following or a variation on the theme:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at mm/dd/yyyy hh:mm:ss
RMAN-06564: must use the TO clause when the instance is started with SPFILE
The second message is a direct response to the following:
rman target /
startup force nomount;
run
{set controlfile autobackup format for device type disk to 'c:\backup\oracle\XE_%F';
# use 'c:\oraclexe\app\oracle\product\10.2.0\server\database\SPF2FILE_%F'
RESTORE SPFILE FROM AUTOBACKUP;
I have no clue how to specify correctly that the SP2FILE.ORA file is the backup of the control file (can provide the script to create the backup if you think it will help, which runs a series of logs to capture settings and then executes the backup.) The backup process was inherited and I cannot explain why the default RMAN process is not being used to create the backup. However, I've been unable to use the default RMAN output to restore on a different server, as well.
Please help - this task is now very late, and I'm not even sure whether I'm asking the correct questions to solve the problem(s) I'm experiencing.

I'm not sure what you mean by the instance 'status'. I install a fresh copy of Oracle Express 10g. Copy over the backup files for the database and logs, copy over the SPFILE..., and attempt to restore, with the errors reported above.
When I install XE, the instance is up and running (as confirmed by the 'home page' of XE being displayed in the browser waiting for logon and password. When I start the process to restore, XE is no longer available (in some form of maintenance mode and unavailable to normal users).
What do you mean 'using pfile/spfile'? How would I 'use'? (I did verify that if I take a 'backup' using the XE tools, I CAN restore on the same instance where I took the backup. Just not on a different, new instance of XE.)
The article is quite interesting, but it seems to assume that I'm working in the same instance where the backup was taken. The instructions also seem to contradict the error messages I presented above.
I don't have any autobackup settings on my brand new copy of XE, so the following command in the article does not seem meaningful to me. Clearly it makes sense to use both a TO and FROM. It seems that what I should be doing is using a 'FROM' where I have the 'TO'; what happens if I point to my backup copy of the SPFILE in the FROM clause instead of 'AUTOBACKUP'? The command string I provided in my original post may be trying to do that, but I can't tell from the source article (which I now have to go find...)
"RMAN> RESTORE SPFILE TO '/tmp/spfileTEMP.ora' FROM AUTOBACKUP;"
Additional question - "DBID"? In express, I do not see any value for DBID. I understand why it would be relevant in a more advanced implementation, with multiple databases being maintained under the same Oracle installation, but it's not clear to me what DBID identifies - the database's internal "primary key" value in a directory of databases, or some other implication.

Oracle 10g on Windows Server off-line database backup - a few questions

I'd like to do an Oracle off-line backup every night. Please tell me what you think about my plan.
First, run this batch file.
set oracle_sid=PLDG
C:\oracle\product\10.2.0\bin\sqlplusw.exe /nolog @c:\oracle\product\oradata\pldg\shutdb.sql
C:\oracle\product\10.2.0\bin\oradim -shutdown -sid PLDG -shuttype srvc
net stop OracleORADB10GTNSListenerPLDG
This is the shutdb.sql script that the above batch file calls.
set echo on
spool C:\oracle\product\oradata\pldg\shutdb.log
connect /@pledgemaker as sysdba
shutdown immediate
spool off
exit
....that should shut down the database.
Now I will copy the files that the following three queries pulls up to another server.
SQL> select name from sys.v_$datafile;
NAME
C:\ORACLE\PRODUCT\ORADATA\PLDG\SYSTEM01.DBF
C:\ORACLE\PRODUCT\ORADATA\PLDG\UNDOTBS01.DBF
C:\ORACLE\PRODUCT\ORADATA\PLDG\SYSAUX01.DBF
C:\ORACLE\PRODUCT\ORADATA\PLDG\DRSYS01.DBF
C:\ORACLE\PRODUCT\ORADATA\PLDG\ODM01.DBF
C:\ORACLE\PRODUCT\ORADATA\PLDG\PLEDGEMAKER_DATA01.DBF
C:\ORACLE\PRODUCT\ORADATA\PLDG\PLEDGEMAKER_INDX01.DBF
C:\ORACLE\PRODUCT\ORADATA\PLDG\TOOLS01.DBF

MEMBER

C:\ORACLE\PRODUCT\ORADATA\PLDG\REDO01B.LOG
C:\ORACLE\PRODUCT\ORADATA\PLDG\REDO02A.LOG
C:\ORACLE\PRODUCT\ORADATA\PLDG\REDO02B.LOG
C:\ORACLE\PRODUCT\ORADATA\PLDG\REDO03A.LOG
C:\ORACLE\PRODUCT\ORADATA\PLDG\REDO03B.LOG
SQL> select name from sys.v_$controlfile;
NAME
C:\ORACLE\PRODUCT\ORADATA\PLDG\CONTROL01.CTL
C:\ORACLE\PRODUCT\ORADATA\PLDG\CONTROL02.CTL
C:\ORACLE\PRODUCT\ORADATA\PLDG\CONTROL03.CTL
After copying the above files, I want to start the database back up. First I run this batch file
set oracle_sid=PLDG
net start OracleORADB10GTNSListenerPLDG
C:\oracle\product\10.2.0\bin\oradim -startup -sid PLDG -starttype srvc,inst
Then run this script.
set echo on
spool C:\oracle\product\oradata\pldg\startdb.log
connect /@pledgemaker as sysdba
startup
spool off
exit
- Is this plan complete?
- Will the filenames that the above three queries retrieve ever change in the future? Or do they remain the same?
- There are other files in the C:\ORACLE\PRODUCT\ORADATA\PLDG\ directory, such as TEMP01.DBF. I am assuming that I do not need to back these files up. Is this correct?
Thanks so much for your help!

I agree that I should eventually get to learning RMAN and should understand it thoroughly. I've read a lot of the documentation on it but it can be really confusing. I mean there are 666 page books on Oracle backups - it is intimidating.

Edited by: DataHandle on Jun 14, 2012 9:49 AMYes, the official documentation can be pretty overwhelming. I suggest you go to amazon and look up "RMAN Backup and Recovery" by Hart and Freeman. It is very well written and cuts through a lot of the clutter of the actual reference manual.
For the immediate, here's what you need to do
log on the the sever as 'oracle' - or whoever owns the oracle installation
then

i need to know how to create a back up disc in the latest version of i tunes the directions in the article dont apply to my version it says to go to file then library then to back up to disc from the menu but back up to disc doesnt appear in my menu

Hi and welcome to Forum!
You should learn RMAN (Recovery Manager) to do your backup with Oracle suggested way
Then you can restore and recover this backup in any instance
For more information, you can refer to below listed documentations :
[Backup and Recovery Basics|http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/toc.htm]

Accessing unix script from Apex

Hi There,
Is it possible to access unix script from apex?
Or to run a batch file through apex?
Please help!!
Thanks in advance,
Pushpesh Pallav

The solution depends on the purpose of the script.
"I want to run a database backup"
learn RMAN, create an RMAN repository, and have Oracle backup itself
"I want to backup a schema on demand"
use dbms_datapump
"I want to put/get a blob to/from a file on an internal machine"
one method:
Install and register Oracle Agent on internal machine
use dbms_scheduler.put_file()/get_file()
"I want to get a file on an external machine that is available via HTTP(s)"
I've used ORDDoc( 'http://...' ) to get this file.
"I want to run the script and parse the results. - no input parameters are needed"
Enhance the script to return CSV like results
Then, create an EXTERNAL TABLE with a preprocessor
".. and the script returns performance matrix of a server"
I believe Oracle has already written (and incorporated) those scripts.
"..and the script checks to see if a new file exists"
DBMS_SCHEDULER.FILE_WATCHER()
"I want to give it some parameters,run the script, and then parse the results"
Wrap the script with SOAP/REST.
Example wrapper stuff:

How to become a junior DBA?

Hi everyone,
I finished my oracle training program and want to become a junior DBA.
I know 10-month training program is not enough for becoming a junior DBA. SO, could someone please tell me to the way or your story to become a junior DBA?
Thanks in advance for any advice!

and then install a patches the OP would have to have a MetaLink account to get patches. Since he doesn't even have a DBA job, it's extremely doubtful he has access to MetaLink
to ur oracle for updating by doing these you can learn how to update the database it is most important role in DBA and make some tuning to your database without using any tools go through sql optimization method by doing these you can learn all commands very well. then after practicing all these take your database backup and unistall oracle in your system after doing that again install oracle and import that previous backup database by doing these you can learn importing and exporting concepts and also learn RMAN concepts when ever ur attending any interview please go through all these concepts.
better luck for your future.
