  • The response output from the command will be sent back to the terminal session.
ESMAC
  • DB commands can be entered via the ESMAC IMS Control panel.
  • The response output is sent back to the ESMAC panel.
JCL
  • DB commands can be entered via the IMSDBU JCL interface using the PARM parameter
  • The response output is sent back to the job in the SYSOUT DD for the job step.
  • Step condition code is set if command fails.
  • Sample JCL step
