Backup of application file system is also required ?

Hi,
Basic question.
Suppose database is creashed and we have restored it with cold backup taken 2 days back.
How do Oracle Application file system will be in sync with database?
We need to backup the application file system also ?
Thanks,
Kishore

Hi,
It's also worth mentioning that your concurrent logs in the application file system will be out of sync with the records in the database.
If you restore the database from a backup taken a couple of days ago then the records in FND_CONCURRENT_REQUESTS will be a couple of days old, but the users will have been running requests since the backup was made and creating files in $APPLCSF/log/<context>. The danger is that when you restart the environment the users start to run concurrent requests and the output of the request will be appended to the end of the existing logfile.
So best to find the maximum request number in the table and remove any output files newer than that to avoid confusion.

Application file system deleted R12.1.3

Hi,
In one of our development R12.1.3 instance(db 11.2.0.3) application file system got deleted accidentally. Please help us in getting the EBS instance up.
1. We have a backup taken on 27th Oct.(Both database and application )
2. We applied 8/10 patches during this period and couple of rounds of testing.
3. Application file system got deleted accidentally on 4th Nov. No issues on Database node .
I want to continue using the same database and old application file system.
Is it possible !!!!! (as we have applied patches within this period)
Please share your thoughts if it can be done ! ! !
Regards,
Djay

Hi Djay,
You may restore the application binary files from your backup, and re-apply the patch. So the necessary application level binaries will be re-generated while the necessary coding at the DB level will also be re-applied.
Note: When re-applying an already existing patch it prompts you that the patch has been already applied and do you wish to re-apply. Just say yes and proceed
Also let us know, what file did you really delete so that we may better assist you.
Thanks &

SAP Backups ; R/3 & file system

Hello,
What is the different between SAP R/3 backup and SAP File System backup?
what are the files that backing up in each cases
To which back up does the oracle DB fit in. (Data Files,Control files, Redo Logs, SPFILE)
To which back up does the O/S files fit in. (here Suse O/S)
thankx

There is not any concept of SAP file system backup.....it means OS level file system backup.
SAP R/3 backup can backed up all the sapdata(database) files, controlfiles as well as redologs.
OS filesystem level backup can backed up all the files based on your requirement and rotation.
Both backups you can use for restorations.....SAP R/3 backup will take all the responsibilities in backup as well as in restoration.
but in OS level backup first you must know which files need to be backed up and what exactly the all directoruies contains.

Shared Application File System.

After moving to shared application tier in production
In $IAS_ORACLE_HOME/Apache/Apache/conf I see the security.conf file has version security_ux_ias1022.conf 115.25 2009/04/23 10:04:40 mmanku ship $
but in $CONFIG_TOP/Apache/Apache/conf the sercurity.conf file has the following version security_ux_ias1022.conf 115.29 2009/12/21 05:56:02 sbandla ship $
Which top does oracle use ?
why is the shared IAS Home have a lower version of than the CONFIG_TOP
why does not the one which is not used gets deleted?

Shared and non-shared application file system in R12

Hi,
We have a oracle apps 11.5.10.2 on mutli node architecture with node 1 hosting DB,CCM and admin while node 2 hosting Form and web servers on Windows 2003.
Some of our Products are in Shared status(Installation) like AD,AU etc and I found that R12 currently does not support the shared file system infrastructure on application tier server nodes running on Windows platforms
Metalink note:384248.1
what will be the impact of this if we plan for R12 upgrade?
Thanks!
Shekhar

Hi Shekar,

I'm slightly confused by your question. Shared application tier file system isn't supported on Windows platforms in 11i, either. From Note 233428.1: 
<blockquote>
The shared file system infrastructure is not supported on application tier server nodes running Windows platforms or using Oracle9iAS releases earlier than 1.0.2.2.2. Application tier nodes must be running on the same operating system to implement a shared file system.
</blockquote>

Are you perhaps referring to the licensing status of your Applications products (i.e. either Installed, Shared, or Not Installed) from the Installed Products report in OAM? If yes, then this should have no impact on your upgrade to R12...those statuses should remain the same when you upgrade. "Shared" in this case relates only to the licensing status of the product, implying that the product is not explicitly licensed (i.e. Installed status), but its functionality is required for used with other Installed products.

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. ;-)

Does Time Machine backup open applications/files?

I recently lost my calendars (in Entourage, Ical, Mobileme, etc.), and wanted to restore from a time machine backup.
I tried to restore the Entourage identity from a day or two before only to see that the date in Time Machine for the file was way old.
I suspected that because I leave the app open all the time, particularly all night when my backups run at 11 pm that the file never got backed up. Does this sound right?
Ical, on the other hand (which is synched to mobile me and entourage), even though I rarely open it and use it, seemed to have the updated data.
How does Time Machine deal with files that are in use?

Entourage needs some special handling. I don't use it, so can't tell you exactly how to do it, but if you search this forum for Entourage you should find a post or two (by Kappy and/or Baltwo, I think) with good advice.

Upgraded my macbook pro to mountain lion. But during windows installation, it refuses coz of FAT file system. Also is it possible to partition after windows installation???

I just upgraded my macbook pro to mountain lion. Now I want to install windows, but during installation using bootcamp, it says windows can't install on FAT partition. I couldn't change it to NTFS. Also how can I partition my hard disk after windows installation. Coz before windows installation, if I partition hard disk, it won't allow me to install windows saying startup disk can't be partitioned.......help would be appreciated.
Thanks

Yosemite does not allow a new installation of XP, but an existing XP installation is self-contained and will continue to work. Does your XP installation use a FAT partition? You may be better off using NTFS and then upgrading to Yosemite.
Will the Yosemite upgrade process delete my Windows XP partition or crash my current BootCamp? Can I still have an option to load OS X or Windows XP (press 'alt/option' key during boot up) after upgraded to Yosemite?
If you have made any re-sizing attempts to WXP partition Yosemite will cause problems, otherwise the Yosemite upgrade leaves XP untouched.
Are there any specific reasons to upgrade to Yosemite?

Oracle DB and File system backup configuration

Hi,
As I understand from the help documents and guides, brbackup, brarchive and brrestore are the tools which are used for backing up and restoring the oracle database and the file system. We have TSM (Trivoli Storage manager) in our infrastructure for managing the backup centrally. Before configuring the backup with TSM, I want to test the backup/restore configuration locally i.e. storing the backup to local file system and then restoring from there. Our backup strategy is to have full online backup on the weekends and incremental backup on the weekdays. Given this, following are the things, I want to test.
1. Full online backup (to local file system)
2. Incremental online backup (to local file system)
3. Restore (from local file system)
I found help documents to be very generic and couldn't get any specific information for the comprehensive configuration to achieve this. Can someone help with end to end configuration?
We are using SAP Portal 7.0 (NW2004s) with Oracle 10g database hosted on AIX server.
Helpful answers will be rewarded
Regards,
Chandra

Thanks for your feedback. I am almost clear about this issue now, except one point need to be confirmed: do you mean that on linux or unix, if required, we can set "direct to disk" from OS level, but for windows, it's default "direct to disk", we do not need to set it manually.
And I have a further question: If a database is stored on a SAN disk, say, a volume from disk array, the disk array could take snapshot for a disk on block level, we need to implement online backup of database. The steps are: alter tablespace begin backup, alter system suspend, take a snapshot of the volume which store all database files, including datafiles, redo logs, archived redo logs, controll file, service parameter file, network parameter files, password file. Do you think this backup is integrity or not. please note, we do not flush the fs cache before all these steps. Let's assume the SAN cache could be flushed automatically. Can I think it's integrity because the redo writes are synchronous.

Backup into file system

Hi
Setting backup-storage with the follwoing configuration is not generating backup files under said location - we are pumping huge volume of data and data(few GB) is not getting backuped up into file system - can you let me know if what is that I missing here?
Thanks

Shared Application Tier File System in Oracle Applications R12

Hi
Recently I came to an environment, here we are having 3 nodes with Shared Application Tier File System - One is Admin & DB and the other two are Applications Nodes(Apache and Forms) with load balancing. Its a Shared Application Tier File system so APPS_TOP is NFS mounted on two Applications Nodes. But i see ADMIN Node INST_TOP is also mounted on these two Applications Nodes...Could you please let me know what for this is????? or for what reasons we can keep like this?????

my question is Admin node and two Application Nodes are having INST_TOPS locally on those nodes it self,the best practice is to have $INST_TOP directory located on a each server local mount directory.
Re: Shared Application File System on Linux
other than that Why ADMIN Node INST_TOP is mounted on these two Application Nodes.you have to check with your admins who implemented initially.but best practice is to have $INST_TOP directory located on a server local mount point.

Backup of application file system is also required ?
