webMethods Adapter Runtime assets, connections, listeners, and notifications are initialized during Integration Servers startup and when packages are loaded. As a part of package loading, the enabled connections connect with the external systems. The listeners and notifications are initialized after the connections are initialized. The communication with external systems can be erroneous due to multiple reasons, such as broken connectivity and others. The communication with external systems also increases the time taken by the packages to load and subsequently increases the Integration Servers startup time. To address this issue, webMethods Adapter Runtime supports parallel asset initialization. For more information, see webMethods Adapter Runtime User's Guide.
