IMSDBU Utility

The IMSDBU utility is a database management tool that offers a wide range of operational control. You can use it to initialize, load, unload and reorganize databases. You can tailor its operation to control file naming conventions, progress reporting, statistics, audit reports, and more.

IMSDBU runs as a standalone utility; a PSB is not required to use it. It operates on physical databases defined using DBDGEN. Because it runs outside of the Application Region, it can provide streamlined operation.

You can access the features of IMSDBU in the following ways:

• An interactive interface similar to a 3270 terminal.
• Using JCL submission by executing the database utility program MFDBUJCL.
• Executing mfims imsdbu at the command line.
• Using the MFIMSDBU application program interface (API).
