Dynamic region adjustment option

With the Dynamic region adjustment option, you can specify whether Data Optimizer should modify region specifications automatically to compensate for additional I/O-related storage areas obtained on an application’s behalf.

For example, if you set the REGION parameter to 800 KB and Data Optimizer requires 400 KB for I/O performance processing, the REGION parameter can be dynamically adjusted to 1200 KB.

The following methods are available to invoke the Dynamic region adjustment option:

  • DRA (available through the dialog or by using DD overrides)
  • HCDRA (available by using a command).
