Abstract

Various enhancements are made to the architecture of a list processor to facilitate its use in implementing a message queue that is shared by queue managers residing across a multisystem complex. A new list structure control—a program list entry identifier indicator, or PLEIDI—is defined to allow the user to specify whether user-defined entry IDs are used when the list is allocated. A new delete list (DL) command is added that sequentially processes list entries in the order in which they exist on the specified list. A new move list entries (MLES) command provides a performance-optimized means to process an input list of entries. New key comparison functions and list monitoring enhancements have also been added. A new type of key called a secondary list entry key (SLEK) allows the user to specify a secondary key value as a means to identify a list entry.
