Once you deploy an adapter you may need to deliver a fix. You can identify the fix to Integration Server through the adapter's package manifest file. Whenever the adapter package is loaded, the "patch_history" field is read from the file and displayed on the adapter's About page. The management of this field is the responsibility of the adapter writer. The Integration Server facilities for creating partial package installations can be used deliver adapter fixes. For more information, see the webMethods Integration Server Administrator’s Guide for your release.
