Switching Data Centers - Challenges
Hi all,
We are in the process of switching our data centers for better service.
We are currently on DataStage 8.1 as of FP1, UNIX - Server Edition.
Our topology:
Engine tier, Metadata repository tier (Oracle) resides on host 'DVETL1'
Websphere App Server resides on host 'DVETL2'
Our new data center folks took images of 'DVETL1' and 'DVETL2', and then restored the images to the new servers called 'DVETL1' and 'DVETL2'. Please note that the new servers at the new data center are still being called with the same exact names as the old data centers.
I still haven't gotten a chance to play with the new servers yet but I have this basic question. Is it even possible to deploy the images to a new servers at a different location and can successfully make it work?
What kind of challenges would I face to make it work? I would appreciate if any one can share their valuable experiences.
Thank you,
Kiran

Yes, it is possible. There are teams in IBM and other companies that do data server migrations every single weekend. They have specialized software for the imaging. The most important thing is for you and your team to test it thoroughly ASAP post-migration.

Thanks all for the positive replies... Its very encouraging...
I will make sure that host names are unchanged in the host files... BUT IP addresses in the host files will definitely change. I believe the host names are embedded in the product, not the IP addresses. But please feel free to correct me if I am wrong.
Happy Friday.

I really doubt that the IP address is embedded anywhere in the software. We have changed IP addresses on our servers without incident.
As PaulVL mentioned, there should be firewall concerns, and also between your Information Servers and all other computers communicating to and from--clients and other servers (FTP, database, MQ, web services, etc.).
IP address changes could require a lot of firewall rule changes.

Yah my bad, went back and searched for some of the topics I thought I was remembering on the subject and it is the host names that are the key.qt_ky wrote:I really doubt that the IP address is embedded anywhere in the software. We have changed IP addresses on our servers without incident.
