Output data set requirements for HALDB Online Reorganization

During the initialization phase for an online reorganization of a HALDB partition, IMS creates any output data sets that do not already exist.

For example, when the input data sets are the A-through-J (and X) set, if the M and P output data sets already exist, but the N and O output data sets do not, IMS creates the N and O data sets and uses the existing M and P data sets.

Any existing output data sets must conform to the HALDB requirements for existing output data sets. Any data in the existing output data sets is overwritten during the copying phase of an online reorganization.
