J2EE Engine 
Setting up the JDBC Connector
...
Using the Visual Admin Tool of the SAP J2EE Engine, set the parameter Maximum Connections of the service JDBC Connector to at least 50.
This value must not exceed the maximum number of simultaneously active connections defined on the database server. This parameter controls the maximum size (number of connections) of the J2EE engines database connection pool. For more information, see DTR Database.

In WAN scenarios, where some DTR clients are connected to
the DTR server application via a WAN, performance might be improved by
configuring the DTR client to request compressed HTTP responses from the
server. For more information on
configuring the server-side 
compression rules,
refer to the Administration Manual.

If your DTR clients connect via an HTTP proxy or firewall to the DTR server, these must be configured to allow passage of the following HTTP methods (since the DTR uses WebDAV and DeltaV protocols):
