I'm planning a new XPages application on a new Lotus Domino server and am wondering
a) is it better to choose Domino 9 rather than Domino 8.5.3 FP2?
b) better to choose Domino 64 bit or 32 bit?
Any advice is greatly appreciated.
If I had the choice of server and client. I would pick Domino 9 server and the 9 client/Designer. This will ensure you have the latest and the greatest, with the extension library installed by default. Only reason to go with the OpenNTF extlibx would be to get the relational DB access through xPages.
If the server is dedicated to Domino and has more than 4GB of RAM I would run Domino64.
I am not sure if this question is best asked on this site or on serverfault?
