PAS for OpenEdge does not support the OpenEdge NameServer or the direct connection modes of the classic AppServer. All connections must use a URL that is similar to what was used for the classic AppServer Internet Adapter (AIA).

For example, an ABL client -URL connection parameter to the CONNECT( ) method might be the following for an AIA connection, which is also shown in a connection parameters string that includes the -sessionModel connection parameter:

"-URL http://host:port/aia/Aia?AppService=asbroker1 -sessionModel Session-free"

The equivalent APSV connection parameter for a PAS for OpenEdge connection might be the following:

"-URL http://host:port/apsv -sessionModel Session-free"
If the apsv URI is apsv, or omitted, then it connects to the default ROOT ABL web application. If apsv is asbroker1WebAppl/apsv, then it connects to the ABL web application with the name, asbroker1WebAppl, which is deployed in the WAR file, asbroker1WebAppl.war.
Note: The APSV connection application model is specified as session-free in the same way as the AIA connection session model.
