SDUMPs are continually getting larger, and the critical nature of SDUMP is continually increasing. So, the component trace (CTRACE) service that provides a method for MVS™ components to collect data about problem events now supports SDUMP. The inclusion of SDUMP in CTRACE assists with diagnosing and debugging SDUMP problems and helps to significantly reduce the amount of time that is required to resolve them.
The following specific enhancements are provided to handle the larger storage capacity:
Larger SUMDUMP buffer
SDUMP CTRACE facility
New SDATA options to limit high virtual common storage in SVC dumps
