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.
