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.

Cisco Expressway Core & Edge Cluster, or Disaster Recovery Setup

Hi All,
Dear experts,
I have two sites HQ & Branch.below are my questions for Expressway Core & Edge Cluster
1. Can i create one cluster for 6 sever for Expressway Core and distribute 3 server in HQ & 3 server in Branch for HA
2. Can i create one cluster for 6 sever for Expressway Edge and distribute 3 server in HQ & 3 server in Branch for HA
3. How would be the DNS SRV records and call flow work if the main site Expressway Edge goes down in HQ. How the Branch Side Expressway Edge becomes active for B2B calls.
4. What is the best design to have disaster recovery for Expressway core and Expressway Edge between Sites(HQ & Branch)
Regards,
Irf

Regarding 1 and 2, as long as the round trip delay is no more than 30ms maximum, you should be fine. I presume the HQ Branch offices for the Expressway-Core have a shared internal network, since the Core goes inside the corporate network, while the Edge goes in the DMZ or outside the network for public access.
For 3, as long as you have your SRV records setup correct, you can set the priority of which office gets used first, and then second, in case of a failure.
I don't have an answer for 4 unfortunately.

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,

Need help for Disaster Recovery setup and configuration

Hi Gurus.
We are planning to have disaster recovery test plan. Normally we setup our network at another site and then restore data there and then do configuration and setup to run SAP system to new network.
But this is little more time consuming. We are planning to do something which will might save our time.
We want to create one Application instance on Central instance on current production server. This instance will be "deactivated" and will not run on production server.
When we will do the disaster recovery, we will restore CI filesystem to Disaster recovery network. That time this new application instance will aslo get copied. Once this is done, we just need to go to this instance and start SAP System. This way we will save our time of configuring the new instance and then starting it.
e.g
Production host -> prdhost1
Central Instance -> /usr/sap/P01/DVEBMGS00
and it's subdirectory: data, work, log, sec
create new application instance -> /usr/sap/P01/D03
and it's subdirectory: data, work, log, sec
create new instance profile -> P01_D03_prdhost1, START_D03_prdhost1
this configuration will be created but SAP instance will not be started. It will be copied to Disaster Recovery new site and in that new network , there we can start this new application instance.
Please let me know if we can do that ? if yes, are we going to face any issue in production?
Other than mentioned above, what FileSystem we need to take care for creating new instance?
Any help will be highly appreciated.
Thanks in advance

Basis CK

Hi!
Sorry but your scenario is a little bit confusing.
Let me guess if I understood, you want to configure a "virtual" instance to be able to use it in case of DR.
I don't advise you to do things that way. Why not use virtual hosts and virtual instances like we do when implementing instances within a cluster or metrocluster.
You must have the license from DR server installed. I you use virtual hosts all DR issues like printers, logon groups, RFC groups, etc... will be solved.
If you use virtual hosts and virtual instances all you need to do is replicate the environment into DR site, restore the system and start production.
Of course... you are using UNIX and within UNIX world all these things are much easier.
Bear in mind that if you have JAVA instances then I think this is the only recommended procedure.

Disaster Recovery setup for SAP Portal

Hello,
I am trying to setup a DR site for our portal system. We are using EMC Recover Point to do the SAN replication between Production and DR site. We are using MSCS cluster with one CI and DI in Production. For DR, we are planning to go with a distributed installation with one portal and database node.
Can I create the DR system using System copy assuming that the SID is going to be the same, and the host names/IP addresses are different. How can we make sure that the custom applications deployment in production is in sync with the DR site? I don't think replicating the database preserves everything as the Java system persists data in both the database and the file system, for example the Software Delivery Manager (SDM) is persisted in the file system.
So, how can I make sure that the file system is also gets replicated between production and DR site? Should I keep the DR system shutdown and bring it up for weekly sync up or it can run parallel with the production system?
Thanks.

Hi,
Regarding the system copy, last time I did one myself (its a while ago so I'm not sure if it is still a limitation) it was not possible to have the Target SID the same as the Destination SID.
If this is not a limitiation anymore then yes you can use the system copy procedure as it also takes the SDM with it.
Cheers,
Benjamin

T4-1 rack mount server as a remote server for disaster recovery setup.

Hi,
I would like to ask some basic questions, as Solaris is not my area.
1)
T4-1 server is a rack mount server. Now, we would like to use it for DR purpose. Can we keep this rack mount server on remote location without conversion kit (to use it as a tower server).
2)
As I am new to this, would like to ask a basic question. This T4-1 server has 4 * 300GB hdd. To expand storage capacity, we would like to add hard disks to this server. Do we have to add 300gb hard disks only ? or we can add 2 new 600 GB hard disks.
Thanks

1) Yes, it does not need to be racked to run. Putting it on a wire rack should work fine. Just verify the power and cooling requirements.
2) You can add new internal disks, the system holds up to 8 internal 2.5" disks. Using a zpool, I would consider adding 4 more 600G disks for a RAIDZ pool, though you can add 2 600G disks and mirror them.

Disaster Recovery Solution

I have 2 copes of the same database on 2 different server at two different locations. I have to synchronize the data 100% between the two databases... Please help me to select an appropriate solution to accomplish this.
The 2 databases should be always online
What I can think of is
- Merge Replication.
- Transactional Replication with Updatable subscription..
If you can point some other solutions that would be really great... how about Mirroring.. If I use this I may need a 2 way mirroring... is this possible.

Hi Sudhakar,
According to your description, there are lots of built-in ways in SQL Server
to make two servers synchronize. Some points you should take into account, for example, how much bandwidth and latency between two server, and the size of two database, how often and how much do data change and so on. you can choose the method
most suited for your needs. Merge replication allows various sites to work autonomously and later merge updates into a single. As other post, you can choose replication as a disaster recovery solution. In database mirroring, secondary database
is in an offline mode while mirroring is in place. This can ensure integrity in the secondary database in the event of a failover being required.

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.

Best Way to setup a disaster Recovery site for a logical standby database

I have a logical standby DB (L1DB) as a reporting db on the same machine as the primary (P1DB). We are planning on building a disaster recovery site with similar hardware and potentially have disk mirroring of atleast the redo log files.
The DR site can hold an additional physical standby (S1DB) for the primary (P1DB). I am trying to understand what would be the best way to setup the Disaster Recovery site for the L1DB logical stdby. Ideally, when the disaster happens, and I no longer have P1DB and L1DB, I should be able to switch to S1DB as the new primary. But how do I setup to have a L2DB that takes the place of L1DB and has its contents and can be setup as a logical standby of S1DB?

If you already setup one logical standby, then you know how it works, so not sure what question you are asking ?
Personally I would setup L2DB as a standby of the original primary P1DB. Having downstream standby databases complicates things, and adds additional lag between primary transaction time and L2DB apply.

UCM setup DR (Disaster Recovery) environment

Hi all,
We did implementation part in production. Now we are planning setup DR (Disaster Recovery) environment.When ever Production will goes down automatically RD will take place to provide continue services to user, But in installation part of RD little bit challenging,let me know below problems how we can override.
1) While installing UCM in DR environment I need to give Production DB schema details, Is it workout (if I give production DB Schema details , is there any effect in production )
2) All ways production and DR both file systems will sync up every time. How we can achieve these thing?
Thanks.

Vijay,
read this document: http://download.oracle.com/docs/cd/E17904_01/doc.1111/e15250/recommendations.htm#CHDGAEEA
In a nutshell:
- as for installation, configuration, etc. I'd suggest you to use images (OracleVM will do you the service and it's almost free)
- you will need to synchronize database AND file system
- if Oracle DB Enterprise Edition is your database, you may use DataGuard to synchronize primary and secondary locations (DG is free in EE, in SE or other databases you may use Oracle Golden Gate or a third party product)
- for file system you will need a 3rd party system (I was recommended TrueCopy - this very much depends who is your HW provider)
Note that you can use file system synchronization even for database - I'd suggest to use Partitioning option, because the size of files that need to be synchronize will be smaller - but you might transfer also errors in the database, whilst DataGuard will transfer only correct transactions, so your secondary db will always be in a consistent state.

MaxDB disaster Recovery site setup

Hello Experts
We are hosting SAP apllication in our datacentre. For one of our customer we need Disaster Recovery site. As planned by our maneegment we are going to have a DR centre at some other location. Our DC and DR are connected by suffcient link.
My SAP Instance is running ion MaxDB database and RHEL5. Can you please suggest me how I should look forward to set up the DR site?
Can I setup a SAP server in my DR site with same SID server will restore the initial backup from DC and then go for log mirroring? In this case I will have to install SAP system with same SID? IP address?

There are several possibilities to approach your goal, for a start check
Note 952783 - FAQ: MaxDB high availability
It has a nice comparison of the different possibilities.

EP6 disaster recovery environment setup

I would like to check if anyone on (EP6 SP2 patch 5, Windows 2003 server platform, Oracle database) who may have setup a disaster recovery (DR) environment (obviously in a different location to their production environment). We are also using KM and collaboration.
We need to create an off-site DR environment for our EP6 solution and need to replicate data to this site every 4-6 hours so that we could recover in the event of a disaster (and not lose more than 6 hours worth of data).
If you know have experience or know of someone who has done this before,(Windows platform), pls let me know.

Hi Rajev,
Duplicating your EP6 installation on a differend server is rather straightforward, so I will not go into that part. With respect to your Oracle DB, one way of doing this would be to cross-link your log files to the DR server. Then in case of recovery, you would only need to bring-up the Oracle DB, apply the log files, and then startup your EP6 instance. Depending on the hardware you're using, your DR environment shoud be able to take over within a matter of 10-15 minutes.

Need recommentation to setup Disaster recovery site

Hi All,
1.What are the basic things we need to analyze before we recommend the business to go for oracle Dataguard for DR setup?
2. Do you know any technology that will replicate the schema from one datacenter[one primary database ] to another datacenter [secondary or replication database]?
3. What are the various option to configure the disaster recovery plan at schema level?
Thanks

Hello;
1.What are the basic things we need to analyze before we recommend the business to go for oracle Dataguard for DR setup?Network - bandwidth requirements. How much Redo do you generate? How far away is the standby site? ( proposed network bandwidth and latency )
Power - UPS requirements ( how will you monitor the standby site )
RMAN requirements - Where would you backup? At the primary site or the standby site? If Standby what is the cost of extra equipment? How far away should the standby site be?
Business needs for data ( 24/7, 6 to 6 Monday - Friday etc ) This would help determine a possible protection mode and what switchover failover options you might need.
Allowed downtime if any ( patches, upgrades etc)
How much data loss can be tolerated if you have network, hardware issues? For Primary site? If standby site is lost?
The idea is to develop a plan that meets your business needs.
2. Do you know any technology that will replicate the schema from one datacenter[one primary database ] to another datacenter [secondary or replication database]?Data Guard Logical Standby since you pick what you want to apply
Data Pump will also work
3. What are the various option to configure the disaster recovery plan at schema level?Going to depend upon how much protect the business requires. If all you want is a copy then Data Pump might work.
If you require zero data loss then Data Guard is the way to go.
Frankly I would not use a Logical Standby, I would use a physical standby so I could switchover.
A Logical Standby is a nice idea, but a physical gives you an exact copy and I believe is much easier to maintain.

SharePoint 2010 backup and restore to test SharePoint environment - testing Disaster recovery

We have a production SharePoint 2010 environment with one Web/App server and one SQL server.
We have a test SharePoint 2010 environment with one server (Sharepoint server and SQL server) and one AD (domain is different from prod environment).
Servers are Windows 2008 R2 and SQL 2008 R2.
Versions are the same on prod and test servers.
We need to setup a test environment with the exact setup as production - we want to try Disaster recovery.
We have performed backup of farm from PROD and we wanted to restore it on our new server in test environment.Backup completed successfully with no errors.
We have tried to restore the whole farm from that backup on test environment using Central administration, but we got message - restore failed with errors.
We choosed NEW CONFIGURATION option during restore, and we set new database names...
Some of the errors are:

Aborted due to error in another component.
Could you please help us to resolve these issues?

I'd totally agree with this. Full fledged functionality isn't the aim of DR, getting the functional parts of your platform back-up before too much time and money is lost.
Anything I can add would be a repeat of what Jesper has wisely said but I would very much encourage you to look at these two resources: -
