There are two RMU Unload commands, as follows:

    o  An RMU Unload command without the After_Journal qualifier
       copies the data from a specified table or view of the database
       into either a specially structured file that contains both the
       data and the metadata or into an RMS file that contains data
       only.

    o  An RMU Unload command with the After_Journal qualifier
       extracts added, modified, and deleted record contents from
       committed transactions from specified tables in one or more
       after-image journal files.
