Disaster recovery - Oracle

Hello!
Is there some simple step-by-step guide for disaster recovery of Enterprise 4.7, WAS 620, Oracle?
I am trying to create a disaster recovery scenario for our production based on DB13 backup and brrestore (I am doing backup to disk). The backup works fine and I have got the new machine to play with restore.
I am not very experienced BC and here's how my unsuccessfull try went on:
1. Installed the new SAP system on the "playground" machine with the file structure same as on production (the system was installed properly, I was able to log-on)
2. Stopped the new system and its database
3. messed a little with init<DBID>.sap until brrestore went on
4. brrestore-ed from the backed-up production files (the entire 'sapbackup' folder):
brrestore -b bdrfydrx.and -m full
; the brrestore run successfully and the files on the new system were replaced by the backed-up production files.
5. Attempted to run SAP: the processes were green for about 1 minute; however, I wasn't able to log on, and then the disp+work died (went not yellow, but rather grey)
6. Stopped the services
7. Replaced kernel with the production kernel (copied the entire 'usr' folder, shared the 'usr\sap' folder as saploc and sapmnt)
8. Attempt to start the services - it got even worse: the SAP<SAPSID>_<SYSNO> service wouldn't start. The popup says that the service returns no error, but it's rather a Windows or internal service error.
And now I'm stuck. Please help! The SAP notes on this matter (such as 96848 - Disaster recovery for SAP R/3 on Oracle) have endless iterations of reference notes, and are not very tutorial-organized. The Installation Guide "Homogeneous and Heterogeneous System Copy..." includes only copy based on running SAPinst to export the database, not on backup/restore.
Is there something better?
Thanks in advance!
Kind regards,
Igor
P.S. If I survive, I promise to write a "restore for dummies" weblog on this.

Hello,
Here is the guide:
http://help.sap.com/saphelp_nw04s/helpdata/en/72/96d34c435c3c4ca5894749ef1435ac/frameset.htm
Also,
I thought after you restroed the brrestore backup, you need to recover you database by restoring all your redo log files to the target server and issuing the command in sqlplus:
recover database until cancel auto;
Can you paste your alert log ?

Disaster Recovery For SAP ECC 6.0 On Oracle

Hi All,
This is our infrastructure
Windows 2003 Server
SAP ECC 6.0
Oracle 10
Legato Networker Client / Library
Actually our Backup Strategy is to do an Online Backup Every Night from monday to saturday. We want to test our backup by doing a Restore. We are assuming a complete loss of the system including hardware.
What we do:
1. Install the SAP System on a new host with the same hardware characteristic of the source system.
2. Install & Configure the legato utility.
3. Copy the E:\oracle\MIS\sapbackup\ directory from the source system to the test system.
4. Them we put the database in mount mode.
5. Execute the command: brrestore -b bdyxwoqv.fnf -m full (bdyxwoqv.fnf-> Full Online Backup that was executed without problems).
It gives the following errors:
BR0386E File 'F:\ORACLE\MIS\SAPDATA2\SR3_10\SR3.DATA10' reported as not found by
backup utility
BR0386E File 'F:\ORACLE\MIS\SAPDATA3\SR3700_9\SR3700.DATA9' reported as not foun
d by backup utility
BR0280I BRRESTORE time stamp: 2008-10-01 17.45.19
BR0279E Return code from 'backint -u MIS -f restore -i E:\oracle\MIS\sapbackup\.
rdyybrzp.lst -t file -p E:\oracle\MIS\102\database\initMIS.utl': 2
BR0374E 0 of 63 files restored by backup utility
BR0280I BRRESTORE time stamp: 2008-10-01 17.45.19
BR0231E Backup utility call failed
BR0406I End of file restore: rdyybrzp.rsb 2008-10-01 17.45.19
BR0280I BRRESTORE time stamp: 2008-10-01 17.45.19
BR0404I BRRESTORE terminated with errors
Since this is a new SAP system it never will find the SAPDATA files because they where on the source system and this is a new test system.
We found the following note:
96848 Disaster recovery for SAP R/3 on Oracle
But this note is for SAP R/3 no for SAP ECC!
It explain that you have to install your SAP system with the System Copy Method (is this the only way??).
2.) Installation of the R/3 System
The installation of SAP software contains the software installation of the database. The initial SAP database should be created again but the SAP data should not be loaded.
Install the SAP system with the Oracle-specific system copy method, which is based on backup/restore. This method is described in the system copy guide for your Product/Release. Refer to Note 659509 for products that are based on Web AS.
3.) Modification of the installation
Above all, you must take into account the mounted file systems at the time of the loss. If necessary create new SAPDATA directories (mount points). These generally identify a disk or a logical storage area (logical volume).
Are we working in the right way? maybe there is a formal procedure to do a Restore from an Online backup when you complete loss your system.
Please some tips.
Best Regards,
Erick Ilarraza

Hi Eric,
Thanks a lot for your reply, I will follow the Note 96848 Disaster recovery for SAP R/3 on ORACLE point 5.
5.) Restore profile and log files, as you sayed in case of disaster we will lost our "source" system.
On the other hand to configure the legato client we take care of the name of the server, we configured the .sap, .cfg and .utl files so in theory the restore will be done on the new test system since we run the brrestore command from that system.
Officially there is not a documentation from SAP to do a Restore from a Online Backup with SAP ECC, SAP Netweaver (ABAP / ABAP + Java). You only have the 96848 note??? I found the following information:
http://help.sap.com/saphelp_nw70/helpdata/en/65/cade3bd0c8545ee10000000a114084/frameset.htm
But there is not a official procedure like a System Copy Guide or Installation Guide.

Oracle Application Server 10g Disaster Recovery

Hi all,
This is regarding Disaster Recovery approach for Oracle Application Server 10g. There are two environments Active (DC-PROD) and Stand-By (DR-PROD). Each environment have 2 nodes where OAS Instances are installed in both nodes and each environment has a Virtual Hostname (Virtual IP) used. The 2 nodes hostnames of DC-PROD environment differs from 2 nodes of the other environment DR-PROD.
However the Virtual Hostname is same between two environments.
The env DC-PROD is setup already and is working fine. Now we have to setup DR-PROD env for disaster Recovery purpose. DR-PROD is also setup independently from DC-PROD. Each env has seperate DB servers in RAC mode. We are using EMC SRDF replication technology to do DB replication between DC-PROD and DR-PROD environments.
There is no disk replication between Oracle Application Servers of two environments DC-PROD and DR-PROD. DC-PROD is NOT setup using Oracle AS Guard for some reasons and we are in a situation that DC-PROD should not be touched at all.
So if the Database is replicated from DC-PROD to DR-PROD servers using EMC SRDF replication technology, while bring up OAS Infra services in DR-PROD node, OC4J is failing to come up. After some workarounds, OC4J cameup but we are unable to login to OIDDAS console.
ssoServer.log shows the following: -

Please provide us the inputs to achieve Disaster Recovery for OAS 10g without using Oracle AS Guard.
This is very urgent and your inputs are greatly appreciated.
Regards,
Mahendra.

Another point to add for the environment details. Both DC-PROD and DR-PROD environments does not have connectivity at all. Only the DB connectivity is there for doing DB replication.
EMC SRDF replication technology is a block by block replication i.e., a disk replication. Hope these details are sufficient for environment specifications.

Disaster recovery in Oracle BPEL

Hi,
For a disaster recovery scenario, how does Oracle BPEL support lost transactions? Is there any mechanisum which takes care of re-sending the lost transactions and checking for duplicates?
As Oracle BPEL maintains state information, does Oracle BPEL take's care of lost transactions on server startup.
Can anyone please, through some light on Disaster recovery in Oracle BPEL.
Thanks and Regards

> I am confused. Option 3 will be restoring backup
Yes - but what will you restore? Everything? If you're running on a cluster it's unlikely that both nodes will fail at the same time so there is still one node that can and will run the software, no?
> and 4 will be sapinst. Isn't it? Are both options supported by SAP?
Yes.
> Is there a SAP standard documentation for building cluster from scratch and build SAP system from backup or sapinst for DR?
The standard installation documentation cover a cluster installation.
> I am sure there will be installation document if it is a fresh installation. But not sure if there is one for DR.
If you have a cluster then you have a high availability already. If a node fails, you will "just" reinstall that node and put it back into the cluster.
What kind of DR scenario are you thinking about?

Fusion Middleware, Disaster Recovery Sites with Oracle Applications

I have oracle applications EBS R12.x.x deployed with one disaster recovery site. I have some composite applications built on SOA 11g suite deployed at OFM which is taking care of my EBS R12.x.x (not disaster recovery site) instance. When my EBS R12.x.x down, is it possible that services deployed at OFM starts taking care of my disaster recovery site.

Oracle VM disaster recovery network meta file discovery fails.

I am using the Oracle White Paper "Oracle VM 3: Integrating Oracle VM into a Disaster Recovery Solution using SAN"
http://www.oracle.com/technetwork/server-storage/vm/ovm3-disaster-recovery-1872591.pdf
The problem I am facing is that during the server discovery process in part 2 step 8 the meta network config files from the Primary site are not being recognized by the servers at the DR Site.
I received no errors during the DR Site server discoverer process which should have picked up the meta network config files brought over from the Primary Site OVM servers. I have rediscovered the servers and I have restarted the servers with no success. I am stuck any help or guidance would be appreciated.
Thank you, Russell

After working with Greg King the Author of "Oracle VM 3: Integrating Oracle VM into a Disaster Recovery Solution using SAN" and Sairam Thota from Oracle support, we have come to the conclusion that this is a bug. We did upgrade to OVM 3.2.6 from OVM 3.2.1 with no success on resolving this issue. However, Greg did get the network config files working on the DR site but he had to do it manually. The SR with Oracle that I created is still open and I am awaiting a bug number to be assigned for this issue.
Thank you, Russell

Oracle Business/Disaster Recovery Test Plan ?

I've been asked to create a business/disaster recovery plan (Cover our Oracle environment) outlining what to test in the event of a DR/BR situation once the DB has been restored. Does anybody have a word template or any information would assist me in this task
Thanks

I cannot give you a templace since that would be a site specific confidential documents; however, you really do not need one.
You might just consider adding a note that the exact steps required would depend on the exact nature of the diaster but in all cases would basically follow the pattern of
restore missing files
forward recovery the restored database using the backed up archive logs
open the restored, recovered database
Upon startup Oracle will check itself for consistency. If the database is found to be consisten, which it should be, then the database will be opened. The application can now be started. No additional checks by the DBA are required.
In the event the database is not consistent then the steps above would be repeated for the file(s) not restored as part of the first attempt and the process repeated. Error information will be logged to the database alert log file.

Disaster recovery of Oracle Apps(financials)

We have an 11i Financials App server and 8i backend database installed on two seperate units. At our remote location, we have a standby database. Archive log files generated by production are copied and applied to the standby. To minimize support costs, we would like to have a Finanncials App server on the same machine as the standby database. The Financial's app server is more for disaster recovery in case the production office is inaccessable for an extended period of time.
Are there any white papers on Financials (Apps) disaster recovery?

Recovering lost data from a very old backup (disaster recovery)

Hi all,
I am trying to restore and recover data from an old DAT-72 cassette. All I know is the date when the backup was taken, that is back in November 2006. I do not know the DBID or anything else except for the date.
To recover this, I bought an internal SCSI HP c7438a DAT-72 tape drive on eBay and installed it on a machine running Windows 2003 Server SP2. I made a fresh Oracle 11g Enterprise Edition installation. HP tape drivers have been installed and Windows sees the tape drive without problem. To act as a Media Manager, I have installed Oracle Secure Backup. Oracle Secure Backup sees the HP tape drive without problems as well.
I have to admit my information about Oracle is not very in-depth. I read quite a lot of documents, but the more I read the more confused I become. The closest thing I can find to my situation is the following guide about disaster recovery:
http://download.oracle.com/docs/cd/B10500_01/server.920/a96566/rcmrecov.htm#1007948
I tried the suggestions in this document without success (details below).
My questions are:
1. Is it possible to retrieve data without knowing the DBID?
2. If not, is it possible to figure out the DBID from the tape? I tried to use dd in cygwin, also booted with Knoppix/Debian and Ubuntu CDs to dump the contents of the tape with dd but all of them failed to see the tape device. If there is any way to dump the raw contents of the tape on Windows, I would also welcome input.
3. Is there any way at all to recover this data from the tape given all the unknowns?
Thanks very much in advance,

Hi 845725,
If the backups were created with OSB might be you can query the tape with obtool.
http://www.stanford.edu/dept/itss/docs/oracle/10gR2/backup.102/b14236/obref_oba.htmTo list pieces you could use <lspiece> within obtool.
http://www.stanford.edu/dept/itss/docs/oracle/10gR2/backup.102/b14236/obref_oba.htm#BHBBIFFEIf this works you should be able to identify the controlfile autobackup if it has the standard naming < c-dbid-date-xx > and you than know the DBID or you are able to restore a controlfile from a backup piece in the output list.
Might be you have to install 9i or 10g rdbms software as 11g was released a year later in 2007.
Anyway goodluck.
Regards,
Tycho

Advice on best way to setup Disaster Recovery for SOA Suite 10.1.3.4

Hi Everyone,
I need some advice on the best way to setup Disaster Recovery for a SOA Suite 10.1.3.4 install deploying JSF/ADF OC4J applications.
The way we are trying to do it at the moment is manually copy the "applications" and "applications-deployments" folders for the OC4J application on the production server, then compress and ship the files across to the DR application server nightly. (We don't require high availability).
In the event of a disaster we then extract the files and copy to the OC4J instance (pre-created and configured) on the DR server. Unfortunately to date we haven't been able to reliably setup a DR application (seem to mostly get 404 errors etc), even though the OC4J application has its connection pool resolved to the DR database and is showing as "up" in the ASConsole.
My question is, is there a more "native" way to do what we are trying to do. We do not have Enterprise version of SOA Suite or 11g database so any advanced recovery features are not an option. The setup is also stand alone, i.e. we are not using clustering or RAC etc.
Any ideas would be really helpful.
Thanks,
Leigh.
PS we are also running the production apps server with Oracle Application server 10g 10.1.2.3.0 as the HTTP apache server (with Forms, Reports and Discoverer deployed) and the SOA Suite 10.1.3 applications use the 10.1.2 HTTP server via the HTTP to AJP bridge. So the 10.1.3 OC4J instance is configured to use AJP on port range 12501 - 12600.

For enterprise solutions, AS Guard would work.
http://download.oracle.com/docs/cd/B25221_04/core.1013/b15977/disasrecov.htm#sthref303
However, since advanced recovery options are not available (as you said), then what you are doing should not be too bad.

What is the quickest to upgrade disaster recovery system to NW04s in MSCS?

Hi,
I have an issue which I need assistance from SAP/Windows 2003 experts.
Hope you can share your opinion on an SAP upgrade issue we're grappling with.
Objective : Upgrade our SAP Bank Analyzer disaster recovery environment from NW04 to NW04s SR2, to be same as production. Both production and disaster recovery (DR) run under two node WIN2003 Enterprise MSCS. The SAP CI usually runs on node A and Oracle 10g runs on node B.
The Oracle software, parameters, database files and the SAP folder \usr\sap are already matching. These files and folders are on EMC mirrored disks, so this will be automatically synchronized from production status.
Therefore I believe it is only the SAP software components on the local hard disks - binaries, DLLs, registry, DCOM, environment variable etc, that need to be upgraded on the two DR machines.
For your information, the current SAP 6.40 instance, Oracle 10g instance, MSCS failover capability are all working in the DR environment as we just did an exercise a month ago to prove this.
 Disaster Recovery Environment :
On shared drives that are synchronized between prod and DR : SAP folder \usr\sap including the kernel binaries, Oracle parameter files, database datafiles, redologs, sapbackup etc.
Issue : What is the quickest and reliable method to achieve the objective? Other than the SAP kernel binaries and profiles, I'm not certain what other related components are updated/replaced that are stored locally on each of the clustered machine.
There are three different approaches we can think of :
1) Repeat the whole NW04s upgrade process in the DR environment. This takes several days. The exposure of not having a disaster recovery environment for several days is a minus.
 or
2) Un-install the SAP CI and MSCS definitions. Synchronise the DR shared disks from production to have the upgraded production NW04s database contents and SAP folder \usr\sap.
Use SAPINST to re-install either traditional CI or ASCS option 'System Copy". And then re-create the MSCS definitions for SAP CI using SAPINST again.
The disadvantage is I can't trial this in any other of our environments. Also, we want to run with the traditional CI instead of ASCS until early next year for other reasons. So we would have to reverse the ASCS back to traditional CI with this method, by reversing the steps in OSS NOTE 101190 "Splitting CI after upgrade to 700".
 or
3) Somehow identify all the SAP components that are stored locally on each machine (eg. environment variables, registry settings, DCOM definitions, DLL in various folders). Then just copy them from Production to DR machines or recreate them. I'm not confident of identifying the local SAP components. And I have not been able to find any good OSS NOTEs or forum threads on this topic. The most helpful OSS NOTE I can find is 112266 point 13 and 19.
Thanks for any input.

Datafiles Mismatch in production & disaster recovery server

Datafiles Mismatch in production & disaster recovery server though everything in sync
We performed all the necessary prerequisites & processes related to DRS switchover successfully also our DRS server is constantly updated through logs application in mount state whan we opened DRS database in mount state it opened successfully however when we issued command
Recover database
It dumped with foll errors:
ora-01122 database file 162 failed verification check
ora-01110 data file 162 </oracle/R3P/sapdata7/r3p*****.data>
ora-01251 unknown file header version read for file 162
as I do not remember the exact name now
However upon comparing the same file at production(which was now in shutdown state) the file sizes were mismatching so we went ahead to copy the datafile from production to DRS in database shutdown state at DRS through RCP utitlity of AIX 5.3 since our Operating system is AIX 5.3
Though this remote copy was success
we again started database in mount state & issued command
Recover database
But still it dump the same error but now for another datafile in DRS
I mean I would appreciate if somebody could point out that despite our DRS was constantly being updated through our Production in terms of continuous log application before this activity logs were sync in both the systems also origlos,mirrorlogs & controlfiles were pulled from production system as it is infact the whole structure was as replica of production system , then why did datafile sizes mismatch??

Oracle 10g Database.
I know about dataguard and i have implemnted same on our other application but not for SAP.
I have ame doubts and I request you to please guide me for the same.
1. SAP License key -- it required hardware key. So will i have to generate license key another hardware key i.e. for machine where standby database.
2. Database on standby site will be in manage recovery mode. Will I have to make any changes or any other file realted to SAP on standby host ? (some i know such as I upgrade SAP kernal, same i have to upgrade at standby host)
Will you give me some link related to document for DR

RMAN backup and restore for Disaster Recovery

Hi Guys,
I am very new to Oracle and have a question about RMAN backup and restore feature. I am simulating a disaster recovery scenario by having two VMs running oracle 11g, say hosta and hostb, hosta is sort of production db and the other a disaster recovery db (one that will be made primary when disaster occurs). My goal is to backup production db using RMAN and restore it on the other machine. For some reason when I restore the db on hostb, the command restores the previous backup but not the most recent one e.g. I took a backup yesterday (09/20) and applied it to the hostb that worked fine, but when I try to apply a fresh backup from today (09/21) it always picks up the old backup. Here's a dump of the screen:

Notice that it reads the backup piece from this location /oracle/app/dev/flash_recovery_are

whereas my latest backups are stored at a different location.
I am executing following steps at the RMAN prompt on hosta and hostb:
hosta (production site)
backup as compressed backupset database plus archivelog
backup current controlfile format'/oracle/oracle_bkup/ctl_%U'
backup spfile
hostb (Disaster site)

Any help will be greatly appreciated.
Thanks,
Rajesh

Thanks guys, I really appreciate all your help here. I redid everything all over again to get all the information you guys wanted. Since I noticed that more eyes are looking into this I am going to reiterate my steps one more time followed by specific answers to questions. My first backup on Host B is located under ..../restore_db/backupset whereas the subsequent one is under .../restore_db/backupset/backupset2.
I take backup on Host A using:
rman target /
backup as compressed backupset database plus archivelog;
backup spfile;
quit;
I restore the backup on Host B using:
set dbid=13732232063;
startup force nomount;
restore spfile to '/oracle/app/dev/product/11.2.0/dbhome_1/dbs/spfileforums.ora' from '/export/home/dev/restore_db/backupset/o1_mf_nnsnf_TAG20110928T171830_787gbpxh_.bkp'
shutdown immediate;
startup force nomount;
restore controlfile from '/export/home/dev/restore_db/backupset/o1_mf_ncsnf_TAG20110928T171638_787gbkxn_.bkp'
quit;
/* restart rman here */
alter database mount;
catalog start with '/export/home/dev/restore_db/backupset' noprompt;
restore database;
recover database;
alter database open resetlogs;
quit;
I take another backup on Host A using (notice no spfile backup this time):
backup as compressed backupset database plus archivelog;
quit;
I restore the database on Host B using:
alter database mount;
catalog start with '/export/home/dev/restore_db/backupset/backupset2' noprompt;
recover database;
alter database open;
quit;
Output of List Backup of database (I have done this after I recovered the second time, also note that it is referring to backupset2 which is were my second backup is stored)
RMAN> list backup of database;
using target database control file instead of recovery catalog

Disaster Recovery from tape library!

Hi,
I am using oracle 10g and Backup Exec 12 as the media management software. How do i perform the disaster recovery. My entire scenario is like this:
Server A has the DB (Database).
Configured Backup Exec with RMAN and took full DB backup along with autobackup of controlfile to the tape.
Server A crashes and is unusable.
Installs Oracle on server B and needs to restore the DB on this new server.
I know the DBID of the DB but how to configure RMAN to work with Backup Exec, so that I can restore the db from the tape library?
When you configure the RMAN integration with Backup Exec, it finds the database running on the server and will perform the integration. But in my case, since the database does not exist, how will the Backup Exec agent configure the integration?
How do we go about the restoration to Server B in this case?
Thanks!

Hi!
I am still not able to restore the db. The scenario is like:
Took a full database backup to tape from server A with controlfile autoconfig
Trying to restore the db on server B. The following is the script used to restore.
connect target /
set dbid=152417844;
startup nomount;
run
+{+
allocate channel sbt1 type 'sbt_tape';
SEND 'BSA_SERVICE_HOST=ipaddress,NBBSA_TOTAL_STREAMS=1';
set controlfile autobackup format for device type 'sbt_tape' to 'cf_%F';
restore spfile from autobackup;
restore controlfile from autobackup;
alter database mount;
restore database;
recover database;
release channel sbt1;
+}+
alter database open resetlogs;
When i try to restore, the output is:
channel sbt1: looking for autobackup on day: 20090624
channel sbt1: looking for autobackup on day: 20090623

Please advice!
