We are planning to have a Android 4.2 - UltraliteJ - Sybase Mobilink - Sybase DB 16.0 setup. Concurrent user sessions will be around 10K with a max upload/download size of 10Mb.
I was wondering if anyone has done this kind of setup and what should ideally be our RAM size?
Yes we did this, and the bottleneck is not the RAM size. The minimum requirements for Sybase DB 16 will suffice. The real challenge is to properly define the upload/download scripts.
