Disaster Recovery Server for EP 6.0

Hello All,
We are running EP 6.0 with Windows 2003 / MSSQL 2005 platform. We would like to have a DR server for the same. Can we prefer the log shipping method to set up DR server?
For ECC we use the log shipping method in our DR server, but I am not sure if this works for Portal. Please clarify
Regards,
Anand

Hello All,
Any help on this?

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>?

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

Hi Anil.
you should be sure if user SAPINPDB exists in the database system and it is mapped to the SAPINPDB user of the DB.... this if you use SQL Server, but the rule should be something like this in other DB systems!!!

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??
Details
SAP version :- 4.7
WAS :- 620
Database :- Oracle 9.2
Operating system :- AIX 5.3

I am in a process of DR Planning.
My present setup :
O/S : HP-UX 11.31
SAP ECC 6
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

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.
Please check these links:

i have a server where O/S installed. i want to make this as a disaster Recovery server.
now i want to know.
1- what is the man power needed.?
2 -which technical guys i needed.?
3-how much time it will take?
4- can a basis consultant only do this job?
5-Is any separate team for DR server installation.
kindly guide me in detail regarding this.

It's possible to do all this with one guy, but if you're inventive you can surely employ more people with this.
> 2 -which technical guys i needed.?
You will need people that are actually capable to do this.
The most likely people for that seem to be HP-UX and Oracle admins.
> 3-how much time it will take?
Depends totally on the business recoverability requirements.
How much downtime can it take until your business breaks?
How much is business willing to pay for that?
Usually you build the whole backup setup around those two questions.
> 4- can a basis consultant only do this job?
Depends on the basis consultant.
Usually those guys can at least recover the database.
> 5-Is any separate team for DR server installation.
Well, if there is one in your company - yes.
Most often and usually there won't be an extrea team for that as ensuring recoverability is one of the prime tasks of every DBA.

Disaster Recovery steps for BO

BO XI R2 SP 1
Oracle10g
Windows 2003
We would like to do a drill for BO recovery and need to know what proper steps would be required.
This is so far I understand; if I'm missing something then please advise.
Take backups of Prod CMS, PMDB and Data warehouse schemas
Restore all these schema's in the DR (disaster recovery) database
Now the issue is when we restore CMS; it shows Prod server information and Infoview doesn't let you log in.
Appreciate any assistance. Thanks

Hi Tim - Thanks for sharing the guide; it was very helpful.
I still have one question;
suppose we take the backup of schemas from production database server connecting to production BO server, say BOPRODmachine.domain.com
and then we restore all schemas in disaster recovery server database and file store on disaster recovery BO server, say BODRmachine.domain.com
How will the restored CMS data recognized this new disaster recovery BO server?
We tried to do that and BODRmachine shows that all servers are running on BOPRODmachine in CMC -> Servers
When we tried to connect via Infoview, it didn't let us as server name was different.
Do we have to rebuild the database for CMS on disaster revocery environment before starting the CMS server?
Please advise. Thanks

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"

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.

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

How to migrate Planning from Production to Disaster-Recovery server?

We are using Planning 11.1.1.3 Oracle repository. Presently our DR Planning Application name is different than production's name, and the DR's Windows server names are different from Production's. Otherwise, all other configuration the same.
How do we migrate Planning from Production to Disaster-Recovery server? We stopped Planning on DR server. Then we exported production planning Oracle repository and imported it to DR Planning. We restarted DR's Planning. DR planning seems to be running fine, but I am afraid to click "Refresh Planning" on DR Planning - it might update Production server. So how can I be sure DR and Production planning are disconnected ?
Is there anything we need to do? This method seems to be faster than migrating with LCM.
Edited by: Essbase Fan on Oct 18, 2010 10:11 AM

You are definitely go about it the correct way, if you are migrating the whole planning application I have to agree it is a safer and quicker route.
The connection information to essbase is stored in the planning system database/schema so as long as you have not migrated that then you should be good to refresh.
To put your mind at rest, log into the planning application and edit the datasource associated with the application then you will see where the essbase server is it is going to refresh.
Cheers

Disaster Recovery scenario for MSCS Production system.

Hi
Our production system is on win2008/sql2008 MSCS. We decided to install a disaster recovery system. We will use a database replication software. If we have a standalone production system, not a MSCS system, i know that i can install Disaster Recory system with same SID and hostname and i don't need any homogeneous system copy procedure to switch to DR system. But in our scenario, we have many hostname (sap cluster group, sql cluster group, hostnames of nodes... etc.).
How can i install my DR system (which hostname.. etc.) to make our DR scenario easy?
Best Regards...

You May have trouble with RFC connections:
So, one possible solution is, your new server name(Host name) should be your message server name to minimise the trouble and you have to maintain this for all RFC connections (to Prod ECC system) to virtual host which could be message server.
If I could think if any other possible issues, I will update.

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.
Regards,
Kailas Padwale.
BASIS Team.

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.
