The way Integration Server behaves when it cannot connect to the Terracotta Server Array depends on whether Integration Server has made the initial connection to the Terracotta Server Array and has obtained the tc-config.xml file. When Integration Server starts up, it connects to the first specified Terracotta Server Array server in the Terracotta Server Array URLs list and downloads the tc-config.xml file. Integration Server then uses the settings in the tc-config.xml file to make connections to the servers in the Terracotta Server Array.
