Step by Step RMAN configuration for full hot backup daily

Dear experts,
i am new to oracle RMAN , i have gone through couple of RMAN guides for configuration ,
i have oracle e-business suite (R12.1.1) and database is ( 11.1.0.7) on red hat enterprise linux 5.3 . All of this is 64 bit.
i have a database about 175 gb which is as usual growing day by day as data entry is taking place.
Untill now we have a cold backup strategy in the midnight 3 am a script down the database and make abc.tar.gz file of 25 gb approx. . This process takes about 100 minutes. But now due to new sales system we want our database up 24/7 .
So we want to configure RMAN hot backup.
I want to take backup on disk.
daily full hot backup.
backupsets
currently database is in no-archivelog
plz help me to proceed with this .

1.please tell me that it is covering all aspects of a backup . Can i do complete recovery with this backup in case of disaster?
Define "all aspects".
2. i only get database and controlfile backup at my location. There is no backup of archivelogs , What happened with
that ?Without seeing the output that rman generated from running the above block, and without seeing all of the persistent rman settings, it is impossible to diagnose anything. I will say that your script looks overly complex.
Just to give you a point of comparison, here's my setup. First the persistent rman settings. Take note of anything that is NOT marked as "default";

using target database control file instead of recovery catalog

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.

RMAN Scripts for 9i RAC

We have just recently started to use Oracle 9i RAC on Red Hat linux 2.1. And we are going to use RMAN for backing up the archived logs.
Currently we have 2 node cluster and the archived logs of respective nodes are on their respective local hard disk. e.g for node1 logs are archived on /arch1 and for node2 on /arch2 individually.
Can I have some sample RMAN scripts for backing and restoring the logs of this individual nodes.?
An early guidance is highly appreciated.
Thanks

you can use the same scripts as you where running before you upgraded to RAC. The main difference is that to distribute the load you can allocate channels from other nodes. A simple backup could be done as follows:
#rman
#connect target /
#connect catalog rman/cat@cat
#run{
#allocate channel ch1 type sbt_tape;
#allocate channel ch2 type sbt_tape;
#configure channel 1 device type 'SBT_TAPE' connect = 'node 1'
#configure channel 2 device type 'SBT_TAPE connect = 'node 2'
#backup database;
that will work (he says) but thats the main difference, remember oracle only recommend you allocate the same number of channels as you have devices (EG if you have 2 tape drives you can allocate 2 channels to maximize effiantcy)...
hope this helps a bit,
Marky Mark...

RMAN Backup script for RAC Database..please suggest

Hi All,
I am currently working on backup policy for RAC Database for my client.The client requirement is to backup while database is shutdown(mount state).I have made below script and could any one please suggest what further things should I need to add with below rman script.
echo "Shutdown Database";date
srvctl stop database -d PROD
srvctl status database -d PROD
echo "Database shutdown on";date
echo "Mount Database ";date
srvctl start instance -d PROD -i "PROD1" -o mount
srvctl status database -d PROD
echo "Start Full Database Backup on";date
$ORACLE_HOME/bin/rman target / nocatalog <<EOF
configure controlfile autobackup on;
configure controlfile autobackup format for device type disk to '/BACKUP/PRODBKP/%F';
run{
allocate channel c1 device type disk connect 'sys/******@node1-vip:1521/PROD';
allocate channel c2 device type disk connect 'sys/*****@node2-vip:1521/PROD';
backup format '/BACKUP/PRODBKP/PROD_df_%t_%s_%p.bak'(database);
backup format '/BACKUP/PRODBKP/archive_%t_%s_%p.bak' archivelog all;
copy current controlfile to '/BACKUP/PRODBKP/PROD.ctl';
delete noprompt obsolete;
release channel c1;
release channel c2;
exit
EOF
echo "RMAN Backup Finished on";date
echo "Shutdown Database";date
srvctl stop database -d PROD
echo "Start Database";date
srvctl start database -d PROD
srvctl status database -d PROD
Please share your experiences.
Regards

Hi,
Some tweaks for your script.
echo "Shutdown Database";date
srvctl stop database -d PROD
srvctl status database -d PROD
echo "Database shutdown on";date
echo "Mount Database ";date
srvctl start instance -d PROD -i "PROD1" -o mount1. If you database does not shutdown properly , does your script stops the execution of next step?
2. configure controlfile autobackup on;
configure controlfile autobackup format for device type disk to '/BACKUP/PRODBKP/%F';(Why you need to configure this every time) ?
It's persistent at db level one time setting (until some other script changes the settings by other dba - else remove that - set the configuration at db level once for all)

Please help with RMAN dup for RAC db

Happy Holidays!! All,
I need help with the following issue:
Both target and auxiliary databases are:
Database version is 10.2.0.3 with 2-node RAC db
Servers are MS 2003
Oracle Clusterware 10.2.0.3
Oracle ASM for storage
I have run the rman dup from RAC to a single instance db for a while. This is the first time I ran from RAC to RAC. This auxiliary db was refreshed before and was up for a while and was managed by server control tool. Now I am trying to refresh it with new backup files from production. I did the following as people suggested:
1)     shutdown instance in the second node.
2)     Startup nomount mode in the first node
3)     Run RMAN dup
It failed in the same place with slightly different errors. I pasted error messages at the bottom. I already created a TAR with Oracle but would like to know if anybody has any info related to this. Also I have several questions to ask:
1)     Should I stop all services related to Oracle in node-2
2)     Should I stop all clustware related services in node-1 except oracleCSServie since ASM uses it?
3)     Is there any way I can finish the dup manually from the place I failed? What going to happen if I don’t finish the rest of the dup and go ahead with “alter database open resetlogs”?
4)     How do I remove the database from under Server control – I already run “srvctl remove database -d atlrac” successfully. Is this all?
Thanks a lot for your help and have a great holiday season!!!

1) Should I stop all services related to Oracle in node-2
No, you just need to stop the second instance.
2) Should I stop all clustware related services in node-1 except oracleCSServie since ASM uses it?
No, you don't need to stop anything. Just have the instance startup nomount.
3) Is there any way I can finish the dup manually from the place I failed? What going to happen if I don’t finish the rest of the dup and go ahead with “alter database open resetlogs”?
You have not shown enough information. Did the restore succeed ? Did the recover succeed ? What was it doing when it failed ?
4) How do I remove the database from under Server control – I already run “srvctl remove database -d atlrac” successfully. Is this all?
Yes, srvctl remove database is all you need. (unless you also want to remove from listener.ora, tnsnames.ora, oratab etc)

RMAN script for Unix

We have decided to abandon user managed hot backups and go with RMAN. Could you critizize the following approach and see if we are missing anything? I am making whole database backup and controlfile and archivelogs. I am using RMAN catalog.
In a Unix script setting all of the environment variables and then
connect target ********
connect catalog *********
configure snapshot controlfile to '${ORACLE_HOME}/snapshot_${ORACLE_SID}_${TIMESTAMP}_ctl';
run {
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
backup database plus archivelogs;
release channel c1;
release channel c2;
p.s. control file autobackup is on
Also, I have these questions:
1. How do I direct the output of this backup to a file?
2. Is there a way to check for errors within this file to see if the backup went ok?
3. Would anyone have a unix shell script example of the above?
4. How do I make sure that catalog is synched with control file and what is on the file system?
5. Is it customary to delete archive logs via RMAN script if, say, my policy is to keep it on the file system for 7 days?
thank you for any input!

Hi,
You didnot mention the db version, assumed it's 10g.
If you planned to schedule this job at os level, you might use crontab (unix). The snapshot controlfile config can set with catalog once, so it's not needed to include in your backup script. Like wise your retention can set as "recovery window of 7 days".
1. How do I direct the output of this backup to a file?
==> inside rman script you might use the following command,
set log to '/home/oracle/rmanbkp.log';
2. Is there a way to check for errors within this file to see if the backup went ok?
==> you might check in the logfile for ORA- and RMAN- errors.
3. Would anyone have a unix shell script example of the above?
I use to schedule this job either by OEM or crontab using rman script file.
4. How do I make sure that catalog is synched with control file and what is on the file system?
RMAN will do auto sync with controlfile.
5. Is it customary to delete archive logs via RMAN script if, say, my policy is to keep it on the file system for 7 days?
Upon successful backup you may delete the archivelogs or you might decide to keep it for 7 days and then delete by applying "delete obsolete" command.
Thanks,
Nirmal

RAC Hot Backup

I have a hot backup script for single-instance.
Any one who want to explain me points to take care in a hot backup for RAC environment?

Hello,
I am sorry to bring this up again since it was last posted on Feb 2007. Does anyone know exactly how to perform user managed backup or at least convince me not to use it in a RAC environment? For example, if my storage array has the snapshot capability and I run Oracle10g RAC on Linux with two nodes cluster using OCFS2 (file systems), can't I just put the database in online backup mode for both instances and just take a snapshot of my Linux volumes? The reason is that I create one shared volume for database datafiles, and one shared volume for online redo logs, and one shared volume for archived logs, in a RAC environment, if one instance fail, then the database is still OK, but if a datafile is missing, then I can just startup one instance, recover the datafile, and then restart the other instance. Is this OK or am I smoking something? Please explain.
Thank you,
TD

Script for daily Incremental Backup with Weekly full back?

Hi Can abybody plz give me the scrip for the daily incremental backup and weekly full backup.
Do we need 2 different scripts each for Incrmental and Full Backup or one will do.
Thanx in advance
Gagan

I will suggest you always
-backup archivelog daily when after yours backup database completion
-keep two days archivelog out of yours database storage to others device or
always take frequent archivelog to tape cartrideg after an hour depends yours
database activity pace.
You should also include archivelog backup within these backup scripts to others teriotry device i.e tape cartridge as well keep frequent archivelog backup if you think yours backup storage space is an issue or if you dont trust on yours backup storage media,keep an alternate tape cartridge for archivleog for frequent archivelog backup after every one hours depends the pace of yours database activity.Either backup archivelog frequently or multiplex the archvivelog to other devices.
Now you probably may confuse thats why i need archivelog backup command within this script when i am going to take incremental/full backup, its due to some thing happened with yours last backup got corrupted then you have alternate to restore before last backup.
Mon      Incremental + Archivelogs
Tue       Incremental + Archvielogs
Wed      Yours Database files got smokesWhat will you do
You will restore Tue backup and will apply alls redo from archivelogs which are generated to other devices yours data chances to be lost is minumum.You may lose only the current archivelog which is not yet to be log switched.If yours archivelog destination devices may corrupt then you have alternate to restore from tape cartridge.
If yours Tue backup cannot be restored even though you validate it after backup then you will have alternate to restore monday backup and you have backup of tue archivelog as well yours two days archivelog is also at another device then you may also recover the database till before crash.In this case you may lose only the current archivelog which is not yet to be log switched.
You cannot pile up archivelog to others device cause they begin to take a serious issue on disk thats why i mentioned two days archivelog to other device.
I hope now you clear why archivelog backup is essential with daily backup either its incremental or non incremental.

OSB / RMAN configuration for recovery area backup

Hi
I am having trouble performing a recovery area backup to tape.
Current config
Media server - attached tape library (OSB installed as media server, admin and client - Contains RMAN Repository) - configured as per guide. I can see the library tapes and have tested an OSB filesystem backup to tape which was fine, this was done from the OSB GUI.
Server 1 - databaseA, DatabaseB (OSB client installed) .
ZFS device - Shared storage where the FRA for DatabaseA belongs. All databaseA backups go here (currently databaseA is running in nonarchivelog mode).
I have set the tape details for databaseA, done a backup to the FRA but the backup recovery area to tape backup just hangs, no real errors and the job list through the obtool and list the job it always has state as 'retryable', I am wondering if I have missed some configuration somewhere? I am using Grid control for this.
I did have a couple of RMAN messages tried to resolve this as per some metalink notes to no avail, I am assuming this is causing the problem? Or am I missing something else?
specification does not match any archived log in the repository
specification does not match any datafile copy in the repository
Can anyone help?

Rest the times on the servers and now get the following errors:
RMAN-00571: ===========================================================

Scripting for Windows Server Backup for Exchange 2010

Hi,
I'm new to writing scripts and was wondering if anyone could assist with writing a script to backup an Exchange Server in a windows 2008 r2 environment. I currently use Windows Server Backup with a full VSS backup to run exchange backups, however,
each backup overwrites the previous one, and i would really like to have multiple backups. I would also like to specify backup log locations, and have emails sent upon successful backups or failed backups. I am trying to write this powershell
but cant seem to get things to work.
Thanks
Debbian

You can use PowerShell in conjunction with the Windows Backup command line utility, wbadmin.exe. The code below should help get you started. I have included the date in order to help maintain multiple back ups, but if you do more than one back up per day,
you will need to change the date format to include the time. You cannot control the built in logging of Windows Backup, but you could collect your own backup information and write that out to a text file. As far as sending emails, look into the Send-MailMessage
cmdlet including the -Attachment parameter that could send your log file with your mail message. Cheers.
$Date = Get-Date -Format 'MM-dd-yyyy'
$Path = "\\server\share\$Date"
New-Item -Path $Path -ItemType Directory | Out-Null
Start-Process wbadmin.exe -ArgumentList "start backup -backupTarget:$Path -allCritical -vssFull -quiet"

Win2000/NT hot backup script

Can someone provide a basci script for online(hot) backup for Oracle9i(8i) on Windows2000/NT server? we have a online application, and plan to back it up every night.
Also, Windows should have administrative tool to schedule the backup by envoking the script every night after we set it up, right?
Many THANKS for your help!!!

Rman backup for rac by oem

Br,Hi,
DB : 10.2 and 11.2
How to schedule rman backup for cluster in OEM?How to schedule without OEM?
If one of the node failed,Is it possible to run in another node automatcially?
How to schduel export/datadump in rac by oem?
Br,
Raj

I Am not using oem, without oem you should write several scripts....
for linux hot backup(archive log enabled):
bck.sh
set ORACLE_SID=mydb
set ORACLE_HOME=....
rman target sys/.... @'.../bck.ora'
bck.ora
run
BACKUP AS COMPRESSED BACKUPSET FORMAT "..../db_%d_%T_%s_%p_%U.bak" INCREMENTAL LEVEL 0 DATABASE PLUS ARCHIVELOG DELETE INPUT FORMAT "...../archivelogBackup/arch_%d_%T_%s_%p_%U.bak";
delete force noprompt obsolete redundancy 3;
backup FORMAT '..../ctl_%d_%T_%s_%p_%U' current controlfile spfile;
And create executable job which instance_id=1 and will run your bck.sh script and create schedule for this job, when first node will down you must change instance_id attribute to second one, and be sure that all backup paths exists in all nodes.
