    Using EAServer with Adaptive Server Anywhere

Configuring EAServer

All components installed in a Sybase EAServer share the same transaction coordinator.

EAServer 3.0 and later offer a choice of transaction coordinators. You must use DTC as the transaction coordinator if you are including Adaptive Server Anywhere in the transactions. This section describes how to configure EAServer 3.0 to use DTC as its transaction coordinator.

The component server in EAServer is named Jaguar.

To configure an EAServer to use the Microsoft DTC transaction model

1. Ensure that your Jaguar server is running.

   On Windows, the Jaguar server commonly runs as a service. To manually start the installed Jaguar server that comes with EAServer 3.0, select Start > Programs > Sybase > EAServer > EAServer.

2. Start Jaguar Manager.

   From the Windows desktop, select Start > Programs > Sybase > EAServer > Jaguar Manager.

3. Connect to the Jaguar server from Jaguar Manager.

   From the Sybase Central menu, choose Tools > Connect > Jaguar Manager. In the connection dialog, enter jagadmin as the User Name, leave the Password field blank, and enter a Host Name of localhost. Click OK to connect.

4. Set the transaction model for the Jaguar server.

   In the left pane, open the Servers folder. In the right pane, right click on the server you wish to configure, and select Server Properties from the drop down menu. Click the Transactions tab, and choose Microsoft DTC as the transaction model. Click OK to complete the operation.
