Bind Break is an internal serialization mechanism in z/OS. It involves signalling the online CPUs, and does not complete until all of the online CPUs have enabled for I/O and External interrupts (not necessarily at the same time). So its cost tends to rise as the number of online CPUs increases. This APAR changed data space delete processing in RSM to reduce the number of Bind Breaks that RSM needs to do when multiple jobs are doing DSPSERV DELETE concurrently.
