If you do not use the included SQL Server, but use your own SQL Server, then you have to consider the following:
- Only SQL Server 2014 may be used for the OOEMC.
- The SQL Server has to run with mixed authentication modes (Mixed Mode). You can modify the settings while installing the SQL Servers or in the SQL Management Studio.
- If the SQL Server is running on another computer than where the OOEMC is installed, you will have to modify the Firewall of the SQL computer so that a connection (e.g. network connection) can be established. You could for instance activate TCP/IP as a means of communication. To do that you have to normally define the TCP Port 1433 as an exception.
