User exit daemon for use with special-purpose processor, mainframe including user exit daemon, and associated methods

Abstract

Certain example embodiments relate to techniques for use with mainframe computing systems that include both general-purpose processors (e.g., CPs) and special-purpose processors that can be used to perform only certain limited operations (e.g., zIIPs). Certain example embodiments automatically help these special-purpose processors perform user exits and other routines thereon, rather than requiring those operations to be performed on general-purpose processors. This approach advantageously can improve system performance when executing programs including these user exits and other routines, and in a preferred embodiment, it can be accomplished in connection with a suitably-configured user exit daemon. In a preferred embodiment, the daemon and its clients can use a user exit property table or the like to communicate with one another about the state of each user exit or other routine that has been analyzed, classified, and possibly modified.
