Configuring Dynamic Ports

In BizTalk Server, you can configure dynamic ports for a WCF-Custom adapter. Because the Oracle Database adapter is a WCF-based adapter, you can dynamically configure a port for the Oracle Database adapter by using message context properties.

For the Oracle Database adapter, the URI, action, and binding may be determined from a property on an incoming message, and then specified in the Expression shape, as shown in the following example:

Request2=Request1;
Request2(WCF.Action)="http://Microsoft.LobServices.OracleDB/2007/03/SCOTT/Table/ACCOUNTACTIVITY/Select";
Request2(WCF.BindingType)="oracleDBBinding";
Request2(WCF.UserName)="SCOTT";
Request2(WCF.Password)="TIGER";
SendPort(Microsoft.XLANGs.BaseTypes.Address)="oracledb://adapdoc/";
SendPort(Microsoft.XLANGs.BaseTypes.TransportType)="WCF-Custom";

Note
If you are using a WCF-OracleDB adapter in BizTalk Server Administration console, you can also specify the transport type as SendPort(Microsoft.XLANGs.BaseTypes.TransportType)="OracleDatabaseAdapter", where OracleDatabaseAdapter is the name with which you added the WCF-OracleDB adapter in BizTalk Server Administration console.

In the above example,

• Request2 message is being created from Request1 message. Both the messages map to an operation schema, which is generated using the Consume Adapter Service BizTalk Project Add-in.
  
  
• SendPort is the name of the logical send port in the BizTalk orchestration.
  
  

The Expression shape is part of the BizTalk orchestration. When you deploy the orchestration, the WCF-custom send port is also created.
