Staging data sets

When you specify SHRLEVEL CHANGE (except an SQLAPPLY load) or SHRLEVEL REFERENCE, LOADPLUS uses staging data sets for shadow copies.

LOADPLUS writes the loaded objects to the staging data sets instead of to the original data sets. At the end of the job, LOADPLUS replaces the original data sets with the staging data sets by using either the rename process or the FASTSWITCH process. The following sections describe these processes.

Whether LOADPLUS renames the data sets or switches them, LOADPLUS leaves the original VSAM data sets intact throughout the load process. This nondestructive process allows you to easily restart from a failure, or make the objects available without having to recover.

For more information about staging data sets, see the following topics:
