Protecting your database during an offline reorganization

When you reorganize your database offline, you delete it. Therefore, you should protect it from system or reorganization failure.

You can protect your existing database by renaming the space it occupies and then defining new database space. You should take an image copy of your database as soon as it is reloaded and before any application programs are run against it. Taking an image copy provides you with a backup copy of the database and establishes a point of recovery with DBRC in case of system failure. You can create image copies of your database using the Database Image Copy utility or the Database Image Copy 2 utility, which are described in detail in IMS Version 15.6 Database Utilities.
