Table 1. General database server group properties
Property Description
Service name or port The service name or port number through which clients may connect to the database. The default value is 0.
Note: The service name or port number must represent a non-zero value in order to start a networked database broker.

When you define multiple server groups for the same configuration, you must assign a unique service name or port number to each server group.
Number of servers (-Mpb) The maximum number of server processes that can be started to service clients.

The default value is 0.
Message buffer size (-Mm) The standard message buffer size in bytes.

OpenEdge uses message buffers to move records (messages) between servers and remote clients. Records (plus 40-byte headers) larger than the message buffer size are fragmented into multiple messages. If your database records are large, increase this parameter to avoid record fragmentation.

However, if the network works more efficiently with small messages, reduce the Message Buffer size value and fragment larger records.

The default value is set dynamically based on your platform (UNIX or Windows) and the type of database (Personal, Workgroup, or Enterprise).
Reporting interval (-rptint) The interval, in minutes, at which the server polls for license usage statistics that are reported in the usage report file.

The default value is 1.
TCP/IP Version (-ipver) The TCP/IP version—IPv4 or IPv6—that the database broker uses to open the database port.

The default value is IPv4.
Client Type (-ServerType) One of the following client types:
  • 4GL only — The server group can service requests only from ABL clients. The settings are the same as those for the Both 4GL and SQL option.
  • SQL only — The server group can service requests only from SQL clients. The settings are the same as those for the Both 4GL and SQL option, except that the Message buffer size and Reporting interval settings are unavailable.
  • Both 4GL and SQL — The server group can service requests from both ABL and SQL clients.
Note: Remember that the client type choice you make here is honored only when you have installed the proper licenses for that client. For example, if you selected the 4GL only option during the OpenEdge installation, choosing the SQL only option or the Both 4GL and SQL option in the management console has no effect. However, if you chose the Both 4GL and SQL option during the OpenEdge installation, choosing SQL only in the management console is valid.
