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.

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.

Disaster Recovery site for Exchange 2013

Hi, I have to build DR site with Exchange 2013 environment and unable to see document for Exchange 2013 perspective.
In new environment will contain 10 CAS/MBS co-located servers in primary datacenter with two mailbox copies and disaster recovery site with 5 Exchange 2013 CAS/MBS co-located servers with one database copy in blocked activation mode. Any document related
to this screnario would be helpful. The required solution is when all the servers in PDC goes down then DR site would be activated at DMZ level and Server level. Can I use same IP subnet/Site for the DR site?

Hi,
Yes, you can use the same subnet for DR site. If you use the same subnet, you need to use stretched VLAN.
Here is a related thread for your reference. (This case is for Exchange 2010, but it also applies to Exchange 2013 DAG deployment)

I want to setup a Disaster Recovery Server for Sharepoint Server 2010

There are four production server running sharepoint server 2010 and one SQL server for
ContentDB management.

DR depends upon your backup stratgies, i.e
1) if you taking full backup of sharepoint using SharePoint tool
2) If you taking just SQL backup( Content DB and Services DB).
3) using the 3rd party tool for backup and recovery.
apart from above, you also have make a decision what point of time you want recovery.
from your questions, what i think for you.
Setup new farm with same SharePoint level.same customization, same services configuration, and same number of web apps.
then backup from Prod server( SQL content DBs) and then restore into new farm and mount them.
this is one time thing, Now you have to make decision, how data move from Prod to QA( i mean frequency i.e daily, monthly etc).
Please remember to mark your question as answered &Vote helpful,if this solves/helps your problem. ****************************************************************************************** Thanks -WS MCITP(SharePoint 2010, 2013) Blog: http://wscheema.com/blog

Disaster Recovery Plan for SAP BW

Dear All,
We are planning for robust Disaster Recovery Site for BW . We have similar R3 & BIW servers at DR site at different location and data is being copied every 3 Hrs.
R3 & BIW at DR site is exact replica of primary site. When primary site is down DR site will act as a primary. In that case we might face data loading issue from DR R3 to DR BW because of source system change. If we change the source system then we loose data consistency and might need initialisation. We are looking for the solution which will involve less efforts to up the system.
Does anyone has done this or overcome this situation ?
Regards,
Manish

Hi Raman,
We are doing disaster recovery test for both ECC and BW systems so whole PR system switched to DR system for some time and then back to PR system. so in that case what precautions we need to take from BW side?
Thanks

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.

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.

Synchronizing Disaster Recovery site with the production server

Hi All,
One of the customer is asking the following query:
"How Disaster recovery site can be synchronized with the production server and how do they switch? Will the web logic server do this for them?"
This customer is having two sites one live and one a DR (Disaster Recovery) site on different location.
Can somebody answer my query?
Thanks in advance.,

Firstly
Is your Datagaurd Physical( Redo Apply) or Logical( SQL apply)?
Does it have Datagaurd Broker?
When Datagaurd is setup in your environment - on the primary database( live database) the Datagaurd users LGWR or/and ARCH process to collect redo data and ship this data to standby ( DR site) and the FAL process to provide client-server mechanism for shipping archived logs to standby.
On standby database, The Datagaurd users RFS process to receive redo records from primary database, the MRP process applies redo information to standby database.
If the Data Gaurd Broker is enabled, Datagaurd also used DMON process to manage and monitor both primary and standby databases as a unified configuration.
When there is any connectivity issue to the standby and when connection is re-established, the accumulated archive logs are automatically shipped and apploed to stanby, until stanby is resynchronized with the primary. This process does not require any administrative intervention.
If there is a very large Archive Gap between the primary and secondary due to some major issue. Then the unshipped archive logs need to be shipped manually from primary to standby and needs to be applied in standby to sync up with primary. For some reason there will also arise rare issues like problem with not applying of archive logs though log shipping is success. So some work arround will solve it.
Comming to planned /unplanned outages of production site.
Datagaurd has Failover and Switchover( planned ) methods, These are not automatic, but have to be explicitly initiated by the administrator( So there will be downtime but minimal). Once initiated, Datagaurd automates the processes involved.

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.

What's the best way to setup a media server/central storage for all of my?

I was wondering what the best way to achieve a central media server for all my iTunes content + iPhoto's, calendar syncing and contact sharing is? This is what I currently have:
iMac 20" Aluminum + External HD Backup (kids)
Macbook Black (wife)
Macbook Pro 15" (me)
Airport Extreme 802.11n (obvious)
TimeCapsule 1TB (wifi backup for wife/me)
I would like to replace my PC in my office with a brand new Mac Pro Nehalem 8-Core, 8GB Ram, and 4TB, and replace my PC laptop in my living room attached to my tv, with an Apple TV.
I want to centralize all our Photos from vacations, etc. Music, videos, movies, that are currently split up over wife's macbook, kids imac and my macbook pro onto my soon to be purchased Mac Pro.
I want to be able to stream everything from my living room via Apple TV for when guests come over, dinner parties, etc. (plus I love apple and it keeps things clean)
I'm currently using MobileMe to sync all of our Calendars and Contacts with my main account, which is great, but MobileMe doesn't sync to family members accounts =
What would I need to do to centralize all this onto my future Mac Pro so that everyone has access all the time when they are home and the key here is, modify/update/change from their machines and sync it back/update it on the Mac Pro.
Also, I'm hoping Snow Leopard has some changes to iTunes to make this a little more possible, since we're right around the corner from this release. I don't really want to spend an additional $900+ on Snow Leopard Server to have to achieve these results, but if it makes it easier, and does the job, then I guess I might. This is all speculation though, since it's not out yet. I'd like to get this all sorted and setup within the next month.
I was considering a Drobo, they say they can throw up iTunes Server but, I appreciate everyone for reading this, and taking the time to respond!
Thanks!

I'm in the process of setting up a smaller (and cheaper) but somewhat similar setup to what you want to do, so maybe one example might help point you in the right direction. My needs consist of a centralized location for data storage, which will include iPhoto libraries (I keep two separate ones), iTunes (which I also want served to the home theater system), something other than my laptop to play internet videos and downloaded content on my TV, all with ideally the lowest cost and energy use possible.
My solution was the new Mini with a FW800 external drive as the server/media hub and Airport gigabit as the network hub (it also handles the backup drive).
FW800 is fast enough to saturate a gigabit ethernet link, so I don't consider that much of a bottleneck. The Mini then has iTunes running at all times with its centralized library on it; it is hooked to the home theater via HDMI-DVI video and optical audio, so it can play music and also handle videos when desired; Front Row with the Apple remote is close enough to an AppleTV that I think it handles that well, and it's more full-featured than an AppleTV. It can further be used to display photos/slideshows/whatever on the TV for guests or such, or to surf from the couch with a wireless mouse/keyboard. You can also toss in an EyeTV for $150 and use that as a DVR if you feel like it.
When I want to edit photos or such on my desktop, the gigabit link is fast enough that I can run iPhoto without noticing any significant slowdown. Its also usable over wireless, though I have a dangling extra network cable to plug into a laptop for full gigabit speed if need be. iTunes, of course, shares its library, which can be played from any of the computers in the house if so desired (iPhoto can do that too if you just want to display).
If I REALLY wanted top speed (though I've even done video editing in iMovie via ethernet without issue), I could use a third party synch app (I like Sync) to mirror any of the content from the mini server to a local drive; this works fine with anything but multi-way synching, such as address books being modified in different locations. I'd probably try to set up one of those Mobile Me clone systems or use a 3rd party app if I needed to do that.
Again, maybe this isn't powerful enough or "synched" enough in terms of local storage for your taste, but the advantage is that a Mini uses a minute fraction of the power of a Mac Pro, so you're saving a lot on electricity if the computer will be powered up at all times as a server, and it's also a lot more full-featured as a home theater media hub than an AppleTV. And, heck, the thing is about as well equipped as my old top-of-the-line G5 tower for a 5th the cost and 1/15th the power and noise.

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.

What is the best way to setup premiere sequence for export when mixing 24fps and 23.976fps for final

What is the best way to setup a premiere sequence for export when mixing 24fps (CG) and 23.976fps (live action) for final output at 23.976 (vimeo and such).
Right now my sequence is at 24fps, and when I export to 23.976, my dialogues seem to shift.
Should I set my sequence at 23.976fps instead of 24fps?
Thanks in advance for the help, and sincere apologies if this is a noob question.
David

That makes it easy. Remove the CGs from the project. Go to Edit>Preferences>Media... and set the Indeterminate Media Timebase to 23.976. Then when you import the image sequence, PP will assign it the correct frame rate.
Edit in a 23.976 sequence.

Hi,
The disaster recovery strategy should include a backup and restore plan that determines which data should be backed up and the procedures that will be used to recover it.

What's the best way to master an MPEG 2 file for DVD Studio Pro.

In version 4.5 of FCP I was able to use QuickTime conversion to encode to MPEG2. Now that option is not there. I hate using compressor 2 to create MPEG 2 because when I do the MPEG 2 files always seem to studder and I don't know why. I shot my project in HDV. It is about 64 minutes long. Any suggestions on the BEST way to master an MPEG 2 file for DVD Studio pro? Thanks in advance!
Peter
PS - I'm using FCP 5

Some people have reported a field reversal problem with HDV to SD DVD encodes. There's an Apple technical document on this issue somewhere, but the problem was supposed to be addressed by a Pro Applications update a couple of years ago... This site might help you get to the bottom of the problem.
