Data set group DD statements

When IMS Index Builder scans the non-partitioned primary database, the JCL DD statements for all the DSGs and the primary index (when HIDAM) can be specified.

If the DD statements are not specified, IMS Index Builder tries to allocate them dynamically. If this happens, IMS dynamic allocation members for these databases must exist in the IMS dynamic allocation library. Otherwise, IMS Index Builder will stop.

Do not specify DD statements for a partitioned primary database; allocation is done by IMS Index Builder by using the appropriate information from the DBRC RECON data set.
