Hi All,
We are planning to migrate our systems from WBIMB 5.0 with CSD 05 to 6.0 with FP05. Totally there are 13 applications which interact with each other via message broker, so there are 3 EAI servers in production now.
My questions are
Is it a good way to merge 3 EAI servers to single EAI server and create 3 different brokers? if so what are its pro and con?
Or it is better just to upgrade the 3 EAI servers to newer versions? if so what are its pro and con?
Will there be any Implementation risk while migrating?? because we have WBI adaptor framework, WBI Adapter for mySAP.com and WBI Adapter for Oracle Apps also.
Please give me some suggestions/  .
Thanks in Advance

Why not to the latest 6.1 ?

When you say 3 EAI Servers you mean 3 hardware boxes, each running one of the 3 brokers ? I suppose these 3 brokers should be talking amongst themselves too ?

Do you mean 1 hardware box with 3 brokers in LPAR ? If yes, it can be done BUT depends on your loads and confidence to have a one box solution.

You might have to upgrade the above too...what do the manuals say ? I hope you are first implementing this onto a staging environment.
Sorry, if I'm asking more questions that giving answers...such situations need a lot of info about the hardware, software, system load etc etc..

Hey Elvis,
I have also suggested for latest Version 6.1 but still waiting for the response.
Yes 1 mean 3 hardware boxes only, which contains a single broker running on it.
Does it make much difference if we deploy all the flows in single broker or 3 brokers in a single machine??
Planning to migrate others also, off course will be doing in staging env 1st. But wanted to know pro and cons before dat.
Regards

The company should have maintained a regular upgrade path...guess no point talking about it now. If 6.0, why are you not looking at the latest fixpack atleast ? I thought it was at 9 or 10.

What we would like to know is if the flows running on the 3 are a mix of all flows for all 13 systems, or you have divided the flows based on which system they integrate, which would mean each broker is unique...

No difference in terms of the software, but all the difference in terms of it's being able to support the enterprise.
How powerful are your current boxes ? Remember that you are talking about putting the load of 3 onto 1...is it capable of running it ?
There are many possibilities here
1. All flows on 1 broker on 1 box means you need to have a powerful box and perhaps use the 'now free boxes' as active-active or active-passive support...in other words this is a 3 boxes with 1 broker each(running all flows).
2. 3 brokers on 1 box could mean they share the system resources. This does not make too much sense. I would rather go with 1st option.
3. 3 Brokers on 1 box could be 3 LPARs, each broker running on each LPAR and thus having it's own system resources (no sharing). No fun, would feel like handicapped brokers.
I would prefer the first as I have 3 boxes doing the same thing and I can upgrade each one by one whenever.
I don't have to worry about situations where the hardware crashes and brings down all 3 brokers.
Wait a while, you might get better suggestions from more experienced guys here.
Regards. |
