In all network environments, you use the Service Name (-S) startup parameter to assign a name to an OpenEdge broker/server. You then address this broker/server from a remote client by using the same value for -S as a startup or database connection parameter. Depending on your network type, you might also have to specify additional addressing criteria for remote clients. In terms of OpenEdge addressing, the Transmission Control Protocol (TCP) uses host addressing.

TCP requires a remote client to explicitly address the database server machine (or host) on which the server runs. In a TCP network, you must use the Host Name (-H) startup parameter to specify the host address. The -H value is the name assigned to the database server machine in your TCP/IP hosts file.

Use Host Name (-H) to identify the host name. For example:

-H host-name

The TCP/IP host-name (address) of the database server machine.

-H localhost

A reserved word that specifies that the database server communicates only with clients on the database server machine. Not applicable for DataServers.
