27 Dec 2016 13:26:40 FATAL ReadResponseFile - com.ca.eiam.installer.exception.BadResponseFileException: DSA port is not available on the machine
The DSA port (509) is not available on the machine. Typically this is due to some other process tying up the port.
Run the following command to find the running process that is using port 509...
lsof -I :509 |grep LISTEN
This will show the process name and pid for the process using port 509. This process must be stopped/killed to free up the port. Once this is done, the installation will no longer fail with the error saying the DSA port is unavailable.
