• DB area addition and modification option file

  This file is used to specify the options that configure an execution environment for the adbmodarea command. Specify information about the data DB area that is to be expanded.

You can allocate block special files as the DB area files to be added. In this case, symbolic links to the block special files are created under the DB directory.
