Different number of Business service endpoint for prod/non prod env in OSB

Question

Hi,
I have a scenario in my project. We have 2 managed servers in all non production environment and 4 servers in production environment.
In non production environments, have added 2 end point uri in the business service. If we create customization file from this, it will have only 2 endpoint uri details.
Now problem is how to get all 4 enpoint uri added for production environment. Dont know how if we try to add 2 uris in customization file will work fine or not. Also it will be very cumbersome as there are more than 100 business services.
Tried with comma seperated urls, but load balancing is not happening. Same thing when cluster address is used.
Any pointers on this will be helpful.
Regards,
Pravin

Hi..
There's several ways to do it.. What I prefer to do is to generate the customization files and have a seperate set for each environment. As you say hand modifying the customization files is a pain (and error prone), so I wrote a program to generate the customization files.. basically it runs against my local dev environment, creates an edit session, modifies the env values (these are held in a properties file (easier to maintain)), exports the customization files and sbconfig jars, then discards the edit session.
I then use a wlst/jmx script to perform the imports and running the customization files, then after the customization is ran, then I have a section that modifies the business service with multiple endpoints to set them up to load balance/failover..
this is the function in my utils script to set the load balancing/failover....
