Pushpith, these are what I think
1. there is no limit on how many domsrvr/webengine you can configure. however, there could be resource
limitation so you would need to know why you need a domsrvr/webengine and know if the resource is
available.
2. there is no requirement that you have to configure domsrvr/webengine pair. for example, you can configure
a domsrvr for handling web service calls and in this case you don't configure webengine. however, when you add
a webengine to the env it is recommended to configure a domsrvr before that so the newly added webengine will
connect to that domsrvr; otherwise the newly configured webengine will use the default domsrvr, which is not
recommended as the default domsrvr has a lot workload already.also, it is recommended that the domsrvr/webengine
pair should be on the same SDM server
Lastly, you could configure multiple webengines to one domsrvr but it is not the other way around.
