State-Changing Actions File

In mirror mode, HPE DAH uses the sca.dat file to determine the state-changing actions that it must distribute to all child servers.

When you are running the HPE DAH in mirror mode, you must ensure that the sca.dat file is present. By default, this file must be in the same directory as the HPE DAH, but you can also set the SCAFileDirectory configuration parameter to the location of this file.

If you upgrade HPE DAH, you might need to download a new sca.dat file from the HPE Big Data customer support site. Refer to the Distributed Action Handler Release Notes.
