Diagnostic data set (EQQDUMP)
The tracker, controller, and server write debugging information to diagnostic data sets when validity checking discovers internal error conditions. When diagnostic information is logged, a 3999 user abend normally accompanies it. For service purposes, always include an EQQDUMP DD statement for every HCL Workload Automation for Z address space, dialog user, batch job, and server.
Diagnostic data sets are usually allocated as DASD data sets, but they can also be allocated to SYSOUT. Usually only a small volume of diagnostic information exists, so an initial allocation of two tracks on DASD should be enough.
