OGG-00770
Failed to connect to MySQL database engine for HOST {0}, DATABASE {1}, USER {2}, PORT {3,number,0}
Cause
One of the Oracle GoldenGate parameters that specifies connection information is incorrect.
Action
Verify the login credentials of the Oracle GoldenGate process (as a database user), the connection port, the database name, and the host name that are specified in the parameter file. In the case of the host name, the name might be incorrectly specified, or the MySQL server could not resolve it. It also is possible that the host name was not specified when the MySQL user was created, so the MySQL system table does not contain an entry for the user.
