RAC backup advice

Hi,
I have running Oracle 11gr2 RAC with R12.0.6 Oracle application. All databases are using ASM disk.
What are the best backup & recovery plan for RAC in ASM for database server?
I'm using RMAN daily backup for Database and Application backup on weekly basis.
thanks

Please refer to "Chapter 7 Managing Backup and Recovery" in (Oracle® Real Application Clusters Administration and Deployment Guide 11g Release 2 (11.2)) manual.

SOS Need RAC Specialist Advice

Hi,
I am working in a Big Company and currently one of our Systems using having RAC 10g have crashed.
And we have very important data that we need to recover in it.
Here is the situation. If I do a startup command in sqlplus I receive this message:
SQL> conn sys as sysdba
Enter password:
Connected to an idle instance.
SQL> startup
ORA-01078: failure in processing system parameters
ORA-01565: error in identifying file '+DATA/mvtptd/spfilemvtptd.ora'
ORA-17503: ksfdopn:2 Failed to open file +DATA/mvtptd/spfilemvtptd.ora
ORA-15077: could not locate ASM instance serving a required diskgroup
I have tried solutions found in the net but it failed to solve our problem.
But when I checked the Oracle Services if All are running, I found out the following Oracle Service in Stop State:
1. OracleOraASM10g_home1TNSListener_<nodename>
2. OracleEVMService
3. OracleCRService
4. Oracle Process Manager
When I tried to run the services from 1 to 3 I receive the following Messages:
For #1 Could not start the OracleOraASM10g_home1TNSListener_<nodename> service on Local Computer. Error 1067: The process terminated unexpectedly.
For #2 The OracleEVMService service on Local Computer started and then stopped. Some services stop automatically if they have no work to do, for example, the Performance Logs and Alerts service.
For #3 Could not start OracleCRService on Local Computer. Error 1068: The dependency service or group failed to start.
For #4 It can Start.
I am planning to reinstall CRS but I am wondering if I will be accidentally lossing data in my ORADATA stored in SAN.
Then I am also planning to reinstall ASM and just reuse the Diskgroups I have but very sceptic and I might also loosing data.
And also I was planning to reinstall everything but formatting the DATA and FLASH Disks and just reattach them. Is this possible?
Hope anyone can help me in my issue and give me advice on what to do.
I have been surfing the net for solutions for the past week and still have no success.
Our target is to restore the db and do a backup of it.
Best Regards,
Frank

APC Power Backup Advice for Small Office

I wasn't sure where to post this but I was hoping someone would not my pointing me to the right forum or offering some advice.
I am trying to put the finishing touches on a conversion to mac and have been looking at buying a Power Backup in part for the power part (no crashes and safe shutdown) but also for surge protection.
I have a MacPro (and a monitor), a Time Machine (for the MBP), 2 - 1TB WD externals, a 500 GB Iomega External (for the MBP), a 3DConnection spaceball device and 2 printers on the "desktop". And then I have a 1 TB Seagate External that I keep plugged in on another table for backing up the MacBookPro now and then.
A. Is there anything else (other than temporary power and surge protection) I should be looking for when purchasing such a piece of hardware?
B. Should I be getting everything on the "desktop" plugged in to a backup device such as this and if so how do I calculate which device to buy?
C. Is it a crime to leave the 1 TB Seagate that is not conveniently located off this backup/surge protection system? I suppose it would be wise to unplug it and only plug it in when I am running a backup?
TIA for any advice. It's been a long haul and I'd love to make sure I am finishing this with some pro level advice/approval.

Hi Jon,
...C. Is it a crime to leave the 1 TB Seagate that is not conveniently located off this backup/surge protection system? I suppose it would be wise to unplug it and only plug it in when I am running a backup?- external hard drives use very little power, you can keep it plugged in to the power back up or not. Since you're not using it often, the odds of it suffering a surge power problem are rare...
A couple of things to consider in that scenario: first, while it's not necessarily true of all external drives, some, such as LaCie, are noted for the early failure of their power bricks. Since I've been using a LaCie power brick for over ten years without a problem, I suspect that's because it's not connected to a power source except when it's in actually in use. Even when an external drive is not actually spinning, the power source is still live and perpetual cooking is probably not good for its health. I follow that rule with all devices that use power bricks, including Seagate and WD external backup drives and no brick has ever quit.
Second, the Seagate external drives I've used tend to run very hot because of poor or nonexistent ventilation. Indeed, the SMART record of one of them showed a heat failure with a 155 degree F. reading "in the past." Especially if leaving the drive plugged in means the drive is actually on, keeping it unplugged except when it's in use is a good idea.

Oracle 11gR2 RAC Backup & Recovery

I am new to Oracle RAC, I have installed Oracle 11gR2 RAC (2 node) on HP-UX with ASM, configured FRA location on ASM.
Now I would like to configure RMAN backup, Can someone give some idea or document to setup RMAN backup for Oracle 11gR2 RAC.

There won't be any different settings for RMAN for RAC except for where and how you would be configuring the Archive logs and place your backups. Both, ideally speaking, should be on the shared storage like ASM but there are other combinations also possible. Review the above given links for the same. That should provide a good starting point.

RAC Backup of archivelogs in local destinations

Suppose there is 10g RAC Database using RMAN Backups.
Suppose It is a 2 node or 4 node RAC with archivelogs going to local destinations in all of them. What command we require to run to make sure all four node archivelogs are backed up at once ?
Is there such a command ? Or shall we run backup archivelog all command in all 4 nodes ?

two ways to do it:
1 automatic
configure parallelism to 4.
Backup archivelog etc.
This will automagically open a channel on each node and run a backup command.
2 semi-automatic
alllocate channel .... connect to 'sys/<password>@tns4node1'
alllocate channel .... connect to 'sys/<password>@tns4node2'
alllocate channel .... connect to 'sys/<password>@tns4node3'
alllocate channel .... connect to 'sys/<password>@tns4node4'
backup archivelog etc
Note: RMAN is a lot smarter than you seem to suggest in your last line.
Actually, you are handicapping recovery by setting up local archives.
If the destination would have been shared, all 4 nodes would automagically participate in recovery.
You may want to reconsider your archivelog strategy.

RAC backup procedure failover

We have Oracle 11gR2 RAC database on two nodes. We also have a RMAN backup script that works fine, using a recovery catalog database which is located in a town 20km from the data center. The script for database backup works fine, and is started from crontab Job or from Oracle dbconsole (for now it works from crontab). A recovery procedure is checked and everything is working properly.
The problem is that the script runs from the first node in the cluster, and if the node is turned off, backup can't be run. How can we ensure that our script have a failover backup version. We also tried to do the backup over dbconsole but this only works if the node from which to start job was started.
Essentially the question is "How to ensure that our backup works, whether or not both nodes are active"

Essentially the question is "How to ensure that our backup works, whether or not both nodes are active"Don't use nodes of clusterware to start backup. You can use the host of recovery catalog database which is located in a town 20km.
Move all scripts of rman to host of recovery catalog and configure the scripts in crontab of host of recovery catalog. The RMAN works as client only the backup is always performed on server side.
Create a Service on RAC to RMAN connect (e.g RMAN_BACKUP). The service should run on nodes 1 of the RAC, but is able to run on node 2 or 3 if nodes 1 are not available. (If you use the default service name of RAC (name of database) and you are using parallelism the RMAN can start a session in each node and the backup be perfomed by all nodes at same time, this is not a problem, but you can have perfomance problems on your environment). Because that I recommend create a Service.
http://download.oracle.com/docs/cd/E11882_01/rac.112/e16795/hafeats.htm
Configure a net service name using the local naming method on host of recovery catalog.
If you are using SCAN Feature do this above, if not put all VIP hostnames on Address.
e.g:
RMAN_BACKUP =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = node-scan.oracle.com)(PORT = 1521))
     (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = RMAN_BACKUP)
)Regardless of the node that is active your backup will be started if a node is active
This will only work if you are performing online backup. I hope so.
Hope this helps,

Help required for RAC backup

Hello Support,
We have Oracle 11g R1 RAC enviornement on Windows 2003 Enterprise.
We want to take full database backup to restore in case of any failure.
We are planning to install Oracle on single instance to different hardware and location having same windows.
I appreciate to have proper steps for analysis please.
Currently what are considering are;
- Shutdown RAC database
- Copy control/datafile/redo log files
- paste to other hardware
- using Oracle configuration manager to create template for the existing RAC database.
please add further steps for anaylsis
Thanks

Copy the Cold Backup.
Startup one instance of the database.
And that's it. You are DONE.
If you want to do a cleaner job you can also
Disable the second instance (thread) and then drop the Redo Log Groups of that thread on the Single Node after you have copied the Cold Backup.
I agree with your customer and disagree with the other posters in this thread. A Cold Backup Restore is much much easier than an RMAN Duplicate.
The documentation, unfortunately, covers scenarios where you delete an ORACLE_HOME and/or a Node from an existing RAC Cluster :
http://download.oracle.com/docs/cd/B28359_01/rac.111/b28254/adddelwin.htm#CHDFAEJB
See the ALTER DATABASE commands : DISABLE INSTANCE and DROP LOGFILE clauses.
http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_1004.htm#i2079942
Do these only the the second database server where you copy the Cold Backup.
Do NOT DO NOT DO NOT DO NOT do anything on the actual RAC environment !!

Q: Oracle RAC backup

Hi Guys,
I'm new in RAC. I have a Oracle RAC database with 2 nodes. I want to know if it is good/appropriate to backup the 2 nodes instead of 1. Since I believe they both use the same database.
Thanks,
Benjo

>
Currently we are backing up two nodes of the Oracle RAC individually. What is on my mind is to backup only 1 node and that is all.
>
It seems to me that you should first get a clear understanding of what to backup . There is only one database to backup in a RAC, regardless of the number of nodes. If you are happy to connect with RMAN to one node and take a backup there, everything is fine. There is no need to connect to the other node and do the same there.
That is, if you have placed the archivelogs on the shared storage. This is a best practice. If they are on node-local devices, there is actually something node specific to backup. Else there is not.
Kind regards

External hard drive and backup advice please

hi,
Sorry if this is a common question to the forum but I have only just registered and need advice that is a bit more taylor made than the other posts I've read.
I am going to be buying an external hard drive - firstly I have read that it's better to get firewire so that if need be I can boot up from it. Is this the case??
I want to make a clone of my hard drive, this can be done using deja vu, but is this the best thing to use? or do i need to get something like carbon copy cloner?
next.....partitioning disks. How is this done and what are the advantages? Why do this? This may be the answer to my next question.....
...I want to use the external drive for (1) making a clone of my HD that I can do each week for backup purposes and (2) using it to copy files onto daily/weekly - keeping it separate from the clone
help would be much appreciated
thanks

Yes.

You can also try SuperDuper to perform the clone.
next.....partitioning disks. How is this done and what are the advantages? Why do this? This may be the answer to my next question.....
To partition a disk, use the Disk Utility in the /Applications/Utilities/ folder. Partitioning a drive on your model of computer will usually only give you benefits if you want to maintain multiple bootable installations of Mac OS X or Linux on a single disk.

Just lost 10+years of work...Backup advice now needed

After loosing 10+ years of work from an external hdd crash + a pc hd crash both withing 10day perios, I now have a new iMac and trying to find the best backup solution PLUS syncing solution with my Macbook Pro and iPhone before picking up and with my photography. Believe me, I don't think I'll ever be the same because of this loos.
After much research, it's time for feedback from others. I have a concept diagram that I created and can be found here of what I currently looking at - this is a WIP: http://gallery.me.com/nvert#100232/backupdiagram&bgcolor=black
Any help/advice is appreciated.
Brad (aka nvert)

BIG thanks to each of you for your suggestions and advice and taking the time to help a bro out. Aside from a few glitches in my diagram (to redondant or out of sequence) I have a better grasp on how to approach this thanks to your input. The question I still can't really figure out is the syncing concept - how to keep my iMac and MBP synced? If both are connected to a NAS RAID setup, can it be programed to 'push' the most current file version to the other computer? Since I travel and make changes on the fly with my MBP and then refine/revise on the iMac, I'd like to find a way that does this efficiently. ay or two..
By the way, more info for everyone regarding my attempts to recover my data:
"The Accident": One evening I knocked my external HDD off the PC tower which sits under my desk on carpet. The drive fell less than 18" - all cords attached - and I'm sure that slowed the fall a bit. Either way, the drive was powered on 24/7 and most likely spinning at the time of the fall. Once I put everything back in place, the ext HDD began clicking. Immediately I shut it down and went to the forums as well as tech help from my university. The click was truly the "click of death". Because my university has a contract with DriveSavers, I sent it to them hoping for the best. After 2 levels of analysis by DS, nothing on the 320GB drive recoverable. What few items they were able to pull off the drive, even they were not able to decipher if those files were jpgs or txt files.
nd my job was willing to foot part of the bill since we already have an account with DriveSavers. I was ready to pay 2K for data recovery and work was willing to meet me part way. The sick irony of it all is that I was looking at another backup level 2 months before this happened - I just couldn't decide on what and now I have lost all originals. I have lots of work on the web but as you all know that format is limiting.
I lost great work, family pics, travel pics, SCUBA pics, published work, work to be published, writing, course+teaching materials, financial data...EVERYTHING YOU HAVE! So....
...For all of you thinking about upgrading...follow your gut and do it now before something like this happens to you. Not to be pessimistic...it will happen eventually. I'm just thankful the house didn't burn etc but loosing all that work is a bit debilitating. At least my Canon is right beside me at this moment...been the first time in over 5 weeks and usually it's always "the appendage" my friends tease me about.
Again, thanks for responding so fast to my post. I already have a MobileMe account setup up to sync my contacts, bookmarks, dock, keychains, etc. I also have it setup to keep my work related teaching docs up to date but that is done by me on a manual "when I think of it" basis. Right now, my 1st priority to to get a NAS RAID going but not sure if both the MBP and iMac should use TM or something like both of you proposed such as CarbonCopy or SuperDuper.
Best to all,

Reconfiguring backup advice

i am trying to reconfigure the backup for my "new used" 2012 mac pro which is replacing my 2006 machine. i am hoping for some solid advice.
right now i am setup with a 2 TB TIME CAPSULE that is wirelessly backing up my 250 GB laptop via TIME MACHINE.
in the Mac Pro i /now/ have a 1 TB OS drive (with data) and a 4 TB "database" drive that i am using to store large database files. i am using the other two hard drive slots in this machine for DAILY CLONES of these two drives. these both run at 1:00 AM.
i am currently considering one of two options:
1. to /add/ the 1 TB OS drive to the 2 TB TIME CAPSULE and have TWO TIME MACHINE backups to this one device. one being my OS drive on the mac pro and the other being my laptop HD which accesses the Time Capsule via Wifi. the mac pro is connected via ethernet to the TIME CAPSULE.
2. buy a new 3 TB drive to use as a TIME MACHINE backup hard drive for the 1 TB OS drive and leave the 2 TB Time Capsule to only backup the laptop.
in both cases i am imagining buying a 4 TB /external/ drive to use as a CLONE of the 4 TB database drive. this obviously means that the OS drive with data gets a Time Machine backup whereas the Database drive does not have a Time Machine backup.
in the past i have also kept "periodic" cloned backups of all these hard drives in an "off site" location in my truck in addition to the internal cloned backups and the time machine backups but i think i am going to take a step back on this and ONLY have the additional periodic cloned backups in the off site location in the truck and to not also have an additional external backup of all these hard drives on my desk.
any help on finalizing all this would be really welcome.

RAC Backup

Hi to All,
In my company,I'll backup the database at the servers with RAC.There is one database instance at 2 servers.I scheduled a backup job at one of them,is it enough,or do I have to do the same thing at the other one?
Can you give me information about backup at RAC Servers?
Thanks...

RAC Backup using RMAN

Hi Gurus
I want to know what are the reason we need to take a backup of all the instacnes means that why should rman create a channel for all the instances while taking a backup? Since RAC used a shared storage, so we can take a backup from any one instance is more enough right? Please clarfiy me.
Regards
Bathrinath

You need to back up all archive log threads one per instance.
If all of your archived redologs for all threads are on shared storage, as far as I know you don't need multiple channels.
If these threads are on local storage, you must allocate a channel per instance or you won't have a complete backup.

RAC backup with RMAN...put backup on diff file system

hello all,
I have not work a lot on SAN storages. One of my client has implementated 9i RAC. Now he wants to Add two more disk in SAN storage (Implemented RAID). So sun engineers will do this but before this i have to take full database backup(80GB database) throught RMAN. The problem or confussion from my side is that the database is on Sun SAN storage and i have to put the Full database backup taken by RMAN on local hard disk on the node (node 1 of rac). Is the possible since the SAN storage is RAW file system (as i guess) and i am putting the backup on local system.
Please help me out ...i have do this in couple of days..
Please tell me prosedure too to how to change the path of backup in RMAN if above is possible..
Its urgent
Thanks and Regards!!
Pankaj Rawat

Two things:
1) You will not have any problems taking RMAN backup for RAC and raw devices. None of them make your backups any different.
2) Based on your post, you are not very confident in your RMAN skills and this is your real problem. What is a must for you - take the backup, copy it on another machine and try to restore from it. Note, that you should NOT look at your original database during restore or take any files from there (even init.ora or spfile). If you don't have this done and don't have exact procedure - consider your backup as useless. This is a conservative approach but believe me - it's wort it when you SAN engineers screw up your storage. And they warned you. ;-)

2 external drives for samples/recording/backup - advice needed

Hi, all!
Recently, I experienced a system drive crash which had taken to nowhere land all my system software, as well as a lot of music applications including Logic Studio, Kontakt 3, plug-ins, etc. However, all my samples and recording projects were residing on a separate external drive and survived.
Now, to prevent such occurrence in the future, I am planning a backup system which includes the following:
G5 Dual 2.5 with 8 GB RAM running OS X 10.5.6
Echo Audio Layla 3G with an interface card installed in one PCI slots
PCI-X SeriTek/1VE2+2 interface card residing in 133 bus slot and connected via eSata ports to:
internally:
drive 1 - VelociRaptor 300GB - system (Logic, Kontakt, etc.)
drive 2 - VelociRaptor 300GB - backup of drive 1 (smart backup with SuperDuper)
externally:
drive 3 - OWC Mercury Elite 750GB (samples and recordings)
drive 4 - OWC mercury Elite 750 GB (backup? RAID 1 with drive 3?)
Drive 4 has just arrived and I would like to get the advice of the most efficient way of using two external OWC drives: RAID 1 configuration, or simply backing up the contents of drive 3 to drive 4 via SuperDuper? Forgive me my ignorant question as it is my first time dealing with various RAID configurations: will my drive 3 be erased if I try to arrange two Mercury drives as RAID 1 through disk utility?
Many thanks in advance for your help.
sercher

I use both methods, for different reasons.
I do use SuperDuper to clone my system drive, but I also use other strategies. The benefit of SuperDuper is that it makes a bootable backup. The drawback is that you have to manually run it, and it is advisable to not use your system while it is running.
For this exact reason, Raid 1 has huge benefits over a manual backup scheme, especially for drives writing new data often, or in great amounts. Whatever you write to disk 1 is simultaneously written to disk 2. No manual intervention necessary. If you use an external drive enclosure with a raid chipset in it, the setup is dead easy. Software raid is a different story although it achieves the same level of security. You would have to erase drive 3 to set up software raid with D.U., and it would be less efficient as it uses your system cpu.
Although I keep a bootable clone on hand as I said above, I use this mainly for testing new software (ie. 10.5.7). I use my laptop for many other purposes as well, so new data is added to the internal drive regularly, so I want constant backups: my strategy looks like this:
System backed up constantly using Time Machine (incremental, constant and transparent).
Bootable clones made weekly with SuperDuper.
All media data written to a hardware raid enclosure (I use a G-Raid mini 2, but there are much less costly alternatives). All photos in my Aperture library are referenced and reside on the raid drive, and all audio captured is also written to this drive.
Don't mean to step on any toes, hope this is useful info.
