Falling back from large sequential data sets

If necessary, you can fall back from using large sequential data sets.

To fall back from using large sequential data sets:

1. Define data sets with less than 65,535 tracks on one volume.
2. Perform a database reorganization process (unload from the large sequential data sets and reload onto multiple volumes) if the large sequential data sets are used for databases.
3. Remove the JCL that defines the large sequential data set or sets.
4. Cold start IMS to bring the multivolume data set or sets online.
