We are starting up ACS. ATS and AQ on same host so its a local connection. In this scenario using "-XX:MinRAMPercentage=50 -XX:MaxRAMPercentage=80" might not help. We should use fixed xms and xmx values, otherwise component-wise heapsizes will become more than the actual memory on the host. Also would adding ATS require to increase db pool size and max connections on DB ?
