thanks Karl, I have deployed in my local as simple example and in Dev and QA with the recomendation of Dev Ops team we deployed as multiprocess file example we had brief discussion about considering multiprocess-zk-example and at that time we were unsure of multiprocess-zk-example.
But i will check and let you know if we can change the set up now? One question do we need to do fresh install or can we upgrade to multiprocess-zk-example? Thanks for anticipation.
