OIM Disaster recovery installation

Hi,
I am using OIM 9.1.0.2 BP 12
Oracle DB 10.2.0.4.0
Oracle SOA App server 10.1.3.3
Could someone tell me about how to install Oracle Identity manager in a two different servers (S1 and S2) with Disaster Recovery plan. Means, when one server (S1) went down I should be able to bring up the other server (S2) with the latest data that I should have already synced to it.
Thanks,
Vasanth

this may help you

OIM Disaster Recovery Setup

We are in the processing of completing setup of our production environment with OIM 9.1.0.2. Our setup is running on WAS 6.1 in a two node cluster. We run to an Oracle database. For DR we were planning to take a backup of the production database and restore it on the DR database. We would install OIM in WAS on a DR server as well, pointing to the newly restored database.
Does anyone have any pointers on things to watch out for or configuration changes that may need to be done to allow this to work?
Thanks for any assistance,
Rich Shok

What are the requirements/expectations out of DR? Do you need to replicate the same infra in terms of NFR's e.g. DR site has same performance and user capacity like production then you need to replicate the production infrastructure/architecture in DR data center. However DR strategy completely depends on Client strategy. In Ideal scenerio DR site is cold (i.e. only active in case of production failure) and has same capacity like production. But depending on the client you may want to propose the scale down version of production on DR site and you can also check if you can keep the DR site active also to increase the solution performance. All this need to think through in terms of criticality of the IAM functionality, cost of infrastructure, cost of licence and DR policy for the Client. Now a days every client prefer RAC database but few clients go with Non RAC databases also with storage/disk backup in DR site on every interval.

DR (Disaster Recovery) server installation.

Dear Experts,
We have one server for BI PRD. We are not using it at the moment. We wish
to carry out DR (Disaster Recovery) trial on this server. Regarding thiswe have following queries :
1. Do we require separate SAP License key for this server when setup forDR (already SAP license key exists for it as BI server)
2. We will re-install BI on the same server after our DR test so whetherwe need to regenerate License key for BI or not?
3. We have two R/3 PRD servers in HACMP mode in SAN. Can we take the
backup of R/3 PRD and restore it on DR Trial Server? If yes, whether we
will face any problem for existing PRD server?
4. Whether Existing PRD and Trial DR Server will clash or hang since
these will be in the same local network and SAN
Please advise.

Kailas Padwale.

Hi,
As per your query you have not mentiones here what is your opreting system and whcih SAP verson you are using. If any one need related to implimentaion then we keep in mind to os,sap version,database etc.
Your Question: If you want to DR of PRD then you have to get my answer.
1. Do we require separate SAP License key for this server when setup forDR (already SAP license key exists for it as BI server)
ANS= Yes you can generated from SAP Site becasue now this is BI and you want to DR but for this you have not paid any thing to SAP its free.
2. We will re-install BI on the same server after our DR test so whetherwe need to regenerate License key for BI or not?
ANS=NO becasue you have to use only PRD copy you can not run BI here otherwise how can you say this is DR server. DR Server means you can copy in existing running server, in case you running server get down then within short period you can provide the solution. After rectificaton actual server you will shift in old one.
3. We have two R/3 PRD servers in HACMP mode in SAN. Can we take the
backup of R/3 PRD and restore it on DR Trial Server? If yes, whether we
will face any problem for existing PRD server?
ANS=You can restore backup but you have to take backup only one PRD server and restore it in DR. Just chang your IP Address and rest can be same. You will not face any issue on this if you run in the same network. I will recmond if you use database in DR server itself then good for your running system will not impect.
4. Whether Existing PRD and Trial DR Server will clash or hang since
these will be in the same local network and SAN
ANS= No because you will use seprate IP address and data will be in DR server not in SAN.
In case you need more help, pls get in touch.

OIM 11gR2- Disaster Recovery Setup

Hi,
Does anyone has suggestions/already in place architecture for Deploying OIM11gR2 setup in Disaster Recovery Mode.

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.

Tycho

Welcome to the SQL Server Disaster Recovery and Availability Forum

(Edited 8/14/2009 to correct links - Paul)
Hello everyone and welcome to the SQL Server Disaster Recovery and Availability forum. The goal of this Forum is to offer a gathering place for SQL Server users to discuss:
Using backup and restore
Using DBCC, including interpreting output from CHECKDB and related commands
Diagnosing and recovering from hardware issues
Planning/executing a disaster recovery and/or high-availability strategy, including choosing technologies to use
The forum will have Microsoft experts in all these areas and so we should be able to answer any question. Hopefully everyone on the forum will contribute not only questions, but opinions and answers as well. I’m looking forward to seeing this becoming a vibrant forum.

How to ask a good question
Make sure to give all the pertinent information that people will need to answer your question. Questions like “I got an IO error, any ideas?” or “What’s the best technology for me to use?” will likely go unanswered, or at best just result in a request for more information. Here are some ideas of what to include:
For the “I got an IO error, any ideas?” scenario:
The exact error message. (The SQL Errorlog and Windows Event Logs can be a rich source of information. See the section on error logs below.)
What were you doing when you got the error message?
When did this start happening?
Any troubleshooting you’ve already done. (e.g. “I’ve already checked all the firmware and it’s up-to-date” or "I've run SQLIOStress and everything looks OK" or "I ran DBCC CHECKDB and the output is <blah>")
Any unusual occurrences before the error occurred (e.g. someone tripped the power switch, a disk in a RAID5 array died)
If relevant, the output from ‘DBCC CHECKDB (yourdbname) WITH ALL_ERRORMSGS, NO_INFOMSGS’
The SQL Server version and service pack level
For the “What’s the best technology for me to use?” scenario:
What exactly are you trying to do? Enable local hardware redundancy? Geo-clustering? Instance-level failover? Minimize downtime during recovery from IO errors with a single-system?
What are the SLAs (Service Level Agreements) you must meet? (e.g. an uptime percentage requirement, a minimum data-loss in the event of a disaster requirement, a maximum downtime in the event of a disaster requirement)
What hardware restrictions do you have? (e.g. “I’m limited to a single system” or “I have several worldwide mirror sites but the size of the pipe between them is limited to X Mbps”)
What kind of workload does you application have? (or is it a mixture of applications consolidated on a single server, each with different SLAs) How much transaction log volume is generated?
What kind of regular maintenance does your workload demand that you perform (e.g. “the update pattern of my main table is such that fragmentation increases in the clustered index, slowing down the most common queries so there’s a need to perform some fragmentation removal regularly”)
Finding the Logs
You will often find more information about an error by looking in the Error and Event logs. There are two sets of logs that are interesting:
SQL Error Log: default location: C:\Program Files\Microsoft SQL Server\MSSQL.#\MSSQL\LOG (Note: The # changes depending on the ID number for the installed Instance. This is 1 for the first installation of SQL Server, but if you have mulitple instances, you will need to determine the ID number you’re working with. See the BOL for more information about Instance ID numbers.)
Windows Event Log: Go to the Event Viewer in the Administrative Tools section of the Start Menu. The System event log will show details of IO subsystem problems. The Application event log will show details of SQL Server problems.

hi,I have a question on sql database high availability. I have tried using database mirroring, where I am using sql standard edition, in this database mirroring of synchronous mode is the only option available, and it is giving problem, like sql time out errors on my applicatons since i had put in the database mirroring, as asynchronous is only available on enterprise version, is there any suggestions on this. thanks ---vijay

Planning Disaster Recovery Site for SAP ERP ECC 6.0

Dear All,
I am planning for DR ( Disaster Recovery ) Site. Our current environment is
Production Site
OS        : AIX 5.3
DB        : IBM DB2      version 8.2
SAP      : SAP ERP 6.0 ECC 6
Disaster Recovery Site
OS        : AIX 6.1
DB        : IBM DB2      version 9.5
SAP      : SAP ERP 6.0 ECC 6
I have following confusion in planning the solution.
1 - If I export the data at db level from production site and import that data in DR Site ... than DR Site will be equivalent to Production Site or not.
2 - if answer of point 1 is yes then for SAP DR ... HADR is the best solution or there is any other better solution exist.
regards
Syed Saifuddin

Hello Syed,
If you export from the prod db and import into the disastor recover db then they will be the same provided that SAP environment is all the same. I would recommend that you update the prod side to the same db2 release and fixpack level as soon as possible though as 9.5 (or even better 9.7) has some advanced features that make administration alot easier and save much space.
HADR would be the best setup for disaster recovery in db6 environment.
Check the following documentation which should answer most of your queries.
SAP Note 960843 # DB6:Installation SA MP

and Windows"

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.

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

Disaster Recovery server for SAP and HACMP Cluster script for SAP ECC 6.0

Hi,
I need document for Disaster Recovery server for SAP? I have to configure the DR Server If you have, please share this document if possible.
Have you any cluster script ( HACMP Cluster script for SAP ECC 6.0 ) ?
Thanks & Regards,

Hello, I'm doing a "Plant ECC6 to do a test disatre / Recovery.
During the installation, I would use the same <sidadm> existing as it is in the PRD.
If I tell you to install it during the same <sidadm> it will overwrite what already exists, or do I just enter the password of existing <sidadm>?

Disaster Recovery Soltuion

Hi Everyone,
In the case of Production system unavailable, by the destruction like due to fire or water floods, to avoid the system down-time for couple of days/weeks. We are planning to go for Disaster Recovery solution.
We are planning to go with this solution for our production systems like EHP4 for SAP ERP 6.0/NW 7.01, Solution Manager 7.0 EHP1 systems.
Our landscape was configured in Distributed systems (CI+DB), OS:Win2003 and DB: MS SQL Server 2005.
My doubts are as follows.
1.) I am not able to find any document for DR solution, can anyone guide me where can I find the Documents releated to DR Solution
2.) In the DR Solution Systems as well we need to connect to SAP or not? I mean for remote support or RFC Connections and etc?
3.) Where can I find the Best Practices for DR? I have gone through the Best Practices but not able to find the proper things related to DR.
4.) Can anyone guide me the correct procedure or steps for the DR solution to follow?
I'm planning to do like these OS intallation, DB installation then SAP Installation then copy the Back-up of Production system to Back-up system (DR solution system).
Thanks and Regards

[Disaster recovery] Moving the Essbase server to another physical server

Hi All,
I have 3 Solaris servers part of the EPM 11.1.2.1 environment:
Server1.company.com:
Foundation services, APS, EAS
Server2.company.com:
Essbase Server, Essbase Studio Server.
Installation done on a SAN disk using user ID hypadmin
Server3.company.com:
*Nothing installed here*.
Its the standby server in case Server2 goes down.
Note: I couldn't find any documentation for my below approach... So please understand the risk involved before attempting the same.
Pre-disaster recovery:
I copy the home directory of hypadmin from Server2 to Server3.
During disaster recovery:
I update the Essbase server host name from Server2.company.com to Server3.company.com and similarly update the opmn.xml file.
Finally mount the SAN onto Server2 and start up the services.
Has anyone done the same..? Have you faced any issues? Is there a better way of doing this?
Thanks

Hi,
I believe the usual way of doing this is to have a DR environment, rather than just one server (so for you you would have 2 DR servers). The DR environment has hosts file entries to map Production host names to DR IP addresses.
In DR you are connected to a separate SQL instance and you install and configure the products exactly as you would for Production (exactly the same hostnames).
Then when you are finished you shut down the DR environment and turn on SQL log shipping between the Production and DR databases.
If your Production environment goes down you stop the SQL log shipping, then you can bring up DR and change the DNS names (as required) to give your users access.
For Essbase storage you can either backup Production cubes to DR or mount the Production SAN in DR. The only problem with the latter is that if Production goes down and the SAN is lost you can't bring up DR fully either.
Let me know if you still have questions.

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?

Disaster Recovery in Windows 2003/Cluster, SQL 2000 and R3

Hi,
Can someone share experience/knowledge of disaster recovery scenarios in MSCS/SQL Server/SAP. One of our customer has R3/SQL Server2000/Win 2003 (Cluster).
We would like to evaluate best possible options for the Disaster Recovery which are supported by SAP.
We have thought about
1. Log shipping
2. Standby Database
3. Restore backup on new cluster
4. Homogeneous System copy.
We do not want to go for first two and would like to explore on 3rd and 4th option.
Any links to documents/blogs will be helpful.
Thanks,
Manoj

Crystal Disaster Recovery server

Is there a known best practice to have 2 mirrored Crystal Servers running simulaneously? We have 1 we use in production and we are trying to configure one for disaster recovery. I haven't been able to find anything on this. I welcome any help.

Hello, I'm doing a "Plant ECC6 to do a test disatre / Recovery.
During the installation, I would use the same <sidadm> existing as it is in the PRD.
If I tell you to install it during the same <sidadm> it will overwrite what already exists, or do I just enter the password of existing <sidadm>?
