It is always a good idea to back up the WhereScape RED metadata before running an application load.

A metadata backup can be used to restore the metadata to the state before the application is loaded.

There are two options for backing up the metadata:

  1. In RED, use the Backup > Export the metadata option to backup the metadata, using the data warehouse database's backup utility. Refer to Backup using DB Routines in the WhereScape RED User Guide for more information.

  2. In RED, use the Tools > Build application tables option to build an application of the objects being replaced. This is achieved by selecting the new application files you're about to load in the Previous application box of the Define and building an application distribution window. Refer to Application Creation in the WhereScape RED User Guide for more information.

    Note

    If the table changes in the application are being applied to the data warehouse database, then it is also a good idea to back up the data warehouse tables being changed.
