  3. Process is controlled by the tool that invokes IMS HP Image Copy.
  4. To store reports in the IMS Tools KB repository, use the ITKBLOAD and ITKBSRVR keywords to define IMS Tools KB information in the IMS HP Image Copy site default table.

How to request and control the image copy process

To invoke the image copy process, specify the IMS HALDB Toolkit command parameters that are related to the image copy process in the IMS HALDB Toolkit job.

Control statements for the image copy process are read from the following resources:
  • Command parameters of IMS HALDB Toolkit
  • IMS HP Image Copy site default table, if the site default module is found in the STEPLIB concatenation

ICEIN DD statement is not supported. For more information about invoking the Image Copy function in IMS HALDB Toolkit jobs, see the IMS HALDB Toolkit User's Guide.
