The Jarvis service needs to be externalized for 4.3 portal set up. The documentation Hardware and Software Requirements - CA API Developer Portal - 4.3 - CA Technologies Documentation talks about having a separate server with specific Hardware config. However there is also a link to Jarvis Hardware Optimizer provided underneath which lists a whole host of components and a different nodes, making it difficult to comprehend the use and the relevance of it. Can you please let me know the exact need for this. Is a single server for Jarvis installation not sufficient or we need to take account of the various parameters provided here ?
