Manual intervention for dump creation

IMS produces SDUMPs for some internal errors without manual intervention. However, IMS Wait/Loop or partial loss-of-function conditions require manual intervention to produce an SVC dump.

IMS hangs can be caused by interaction with many address spaces, including those shown in the list below:

  • IMS control region
  • IMS DLI/SAS region
  • DBRC region
  • IRLM region
  • CQS
  • Operations Manager
  • Resource Manager
  • Structured Call Interface
  • Troublesome IMS dependent regions
  • CCTL regions
  • ODBA
  • IXGLOGRC
  • z/OS® Resource Recovery Services
  • APPC
  • VTAM®
  • WLM
  • TCPIP
  • WebSphere® Application Server
  • ESAF - Db2 for z/OS, IBM® MQ, others
