As part of the startup and shutdown services SECTION of the Properties dialog box, you can specify what services webMethods Integration Server should AUTOMATICALLY execute when packages are loaded into memory or unloaded from memory.

• Startup Service: This displays the list of startup services a package can use, as well as the list of startup services assigned to a package. When a webMethods Integration Server loads a package into memory, it automatically executes a startup service. A startup service is useful to generate initialization files and prepare the environment (like SETTING up or cleaning up) before a package is loaded.
• Shutdown Service: This displays the list of shutdown services a package can use, as well as the list of shutdown services assigned to a package. When a webMethods Integration Server unloads a package from memory, it automatically executes a shutdown service. Shutdown services are useful for PERFORMING cleanup tasks like closing files and cleaning TEMPORARY data. In addition, they can be used to capture state information or work-in-progress before a package is unloaded.
