You can specify the extension by setting the ptr parameter to a text or data address within the extension. The extension's file name is noted in the dump, and snap can be used to cause this file to be bundled with the snap data when the dump is collected for sending to IBM®.
Execution Environment
The dmp_kernext kernel service can be called from either the process or interrupt environment.
