DSNARRS

Module DSNARRS is part of the Subsystem Support Subcomponent (SSS) facility. The Subsystem Support Subcomponent facility is responsible for providing support for Db2 to act as a formal z/OS subsystem, and to supply a medium that allows for communication between other (allied) address spaces and Db2. DSNARRS contains Resource Recovery Services Attachment Facility (RRSAF) routines to provide connection services. DSNARRS contains application program support in CSECT DSNAPRH allowing programs to link to the Db2 allied address space connection function.
