Unloading a DEDB offline with FPA

You can unload a DEDB by using the FPA Unload function.

Functions of Unload
The Unload function of FPA efficiently unloads a single DEDB area. It can also concurrently unload multiple DEDB areas without impacting all areas of a database.
Input and output for the Unload function
The Unload function is invoked by the UNLOAD command in the HFPSYSIN DD control statement to unload multiple DEDB areas to QSAM data sets.
Running the Unload function
FPA runs the Unload function as a standard z/OS® batch job. You must specify an EXEC statement and DD statements that define the input and output data sets in your JCL.
Region size requirements for the Unload function
The Unload function of FPA operates in a virtual storage region as z/OS batch job steps. HFPMAIN0 runs in 31-bit addressing mode.
DD statements for the Unload function
DD statements of the FPA Unload function determine the input and output data sets and specify how to run the Unload function.
Utility control statements for the Unload function
The utility control statements for the Unload function define the user description of the GLOBAL command, the UNLOAD command, the optional FILECTL subcommand, and the optional USER_RECORD subcommand, all of which control the Unload process.

Restructuring DEDB areas by using the Unload and the Reload functions of FPA includes several steps.
