Hi,
Again it's me, with my newbie like questions.
I have no experience with mainframes so I always think to map mainframe
world with intel based servers world.
If we have an J2EE based application which we need to deploy on
WebSphere application server, and our J2EE application uses DB2 as its
database, what can be possible deployment schema if our system need to
be highly available, assume that we have redundant network
infrastructures, power supply and a secondary site in another
geographical location.
What I am looking to understand is how our application server instances
and DB2 instances will run inside the each mainframe.
For now, I have two dell servers each one has two instance of
application server, so I have four instance of application server with a
load balancer in front of them to route the request and keep each server
busy enough. I have two Database server instances which handle all
database requests.
I find some information from the articles available in IBM web site,
articles like :
https://www6.software.ibm.com/developerworks/education/websphere/0708_faulhaber/index.html
I found that ODR will act as load balancer instead of web server that I
used with dell servers.
But I can not understand do we install all ODR instances and real work
load servers into one single operating system?
Or we should install several instance of zOS into mainframe LPARs and
then install each of these instances into a separate operating system?
Please, If there are some articles or presentation that can help me
learn more about this schema, give me a link to it.
Thank you.
