ASTC relies on Component Integration Services to handle all communication with remote servers.
ASTC uses the configuration option enable xact coordination. Since ASTC is enabled by default, Component Integration Services is also enabled by default.
This option, enabled by default, allows ASTC to manage all transactions involving remote servers. You must enable Component Integration Services before xact coordination is enabled. While xact coordination is enabled, Component Integration Services cannot be disabled. When xact coordination is enabled, transactional_rpcs are implicitly enabled.
