Coding parameters that produce a synchronous dump

MVS™ produces a synchronous dump when you code BRANCH=NO to request an SVC dump of only the primary address space or global data spaces. Be careful if you code the following parameters:
  • LISTD=list addr. MVS produces a scheduled— not synchronous— dump when the STOKEN represents either an address space that is not the primary address space, or a SCOPE=SINGLE data space owned by a program that is not running in the primary address space.
  • SUBPLST=subpool id list addr. MVS produces a scheduled— not synchronous— dump when the list of address spaces with associated subpool IDs contains at least one address space other than the primary address space.
Do not code the following parameters if you want a synchronous dump; these parameters automatically cause MVS to produce a scheduled dump:
  • ASID=asid addr
  • ASIDLST
  • TYPE=XMEM or TYPE=XMEME
  • LISTA.
