Issue/Introduction

If an IMS tool is invoked by another IMS tool (the execution options are via the DD statement DBOCTRL) those options can only
be passed to the tool which would be executed first.

How can the execution options be passed to another (subsequently) invoked IMS tool?

Resolution

If execution options must be passed to an IMS tool which will be called internally by another IMS tool, the global options parameter DD statement IDIPARM needs to be used.

On the IDIPARM global options dataset, a member matching the corresponding function-related standard member name must be present and this member
must have those options defined which need to be used for this execution.

Example:

DBO reload will be executed with option AUTOINDEXBUILD=YES to build all secondary indexes, which results in SIB being internally invoked by DBO.

To tell SIB to write execution progress information every 1000 records, the IDIPARM dataset must be used in the DBO reload job control, and on this
dataset a member SIBIBLD (standard member name for INDEXBUILD) must be present, containing execution option PROGRESSREPORT=1000.
