License Duration 8 Working Days? That isn't much time for busy DBAs to do much.
Anyway, I attempted to connect to, two MySQL databases. One is on a Redhat Linux and the other Windows 2008R2 and got the error below. I can connect to both from my desktop. DPA Beta 1 is installed on a Windows Server 2008 R2. I'll have ago with Beta 2.
An unknown error has occurred. The provided message is "Could not get JDBC Connection; nested exception is java.sql.SQLNonTransientConnectionException: Could not connect to MYSQLXXX:3307 : Connection timed out: connect".
