The following sections provide information on how to administer and configure the Oracle WebLogic Tuxedo Connector to support Tuxedo CORBA clients and services.
How to Configure Oracle WebLogic Tuxedo Connector for CORBA Service Applications
How to Administer and Configure Oracle WebLogic Tuxedo Connector for Inbound RMI-IIOP
How to Configure Oracle WebLogic Tuxedo Connector for Outbound RMI-IIOP
For more information on CORBA applications, see "Tuxedo CORBA".
This section provides information on how to configure a WTC Service to support a call to a Tuxedo CORBA server from a WebLogic Server EJB. Use the following steps to configure your WTC Service:
Configure Local Tuxedo Access Points WebLogic Server applications.
Configure Remote Tuxedo Access Points for your Tuxedo CORBA domain.
Configure Imported Services.
Set Resource Name
to //domain_id
where domain_id
is DOMAINID
specified in the Tuxedo UBBCONFIG
file of the remote Tuxedo domain where the object is deployed. The maximum length of this unique identifier for CORBA domains is 15 characters including the //
.
Set Local Access Point
to the value of the Local Access Point
attribute of your Remote Tuxedo Access Point.
Set the Remote Access Point List
to the value of the Access Point Id
attribute of the Remote Tuxedo Access Point.
For information on how to develop client applications that call a Tuxedo CORBA service using a WebLogic Server EJB, see the Oracle Fusion Middleware Tuxedo Connector Programmer's Guide for Oracle WebLogic Server.
For more information on how to configure your WTC Service, see Configuring Oracle WebLogic Tuxedo Connector for Your Applications.
The following WTC Service (represented by the WTCServer
MBean in the config.xml
file) provides an example of how to configure an Imported Services configuration for a TUXEDO CORBA server.

The following example Tuxedo UBB configuration file has a DOMAINID
name of simpapp. The DOMAINID
name is used in the Resource Name
attribute of the Imported Services configuration of your WTC Service.

This section provides information on how to administer your application environment and configure your WTC Service to enable Tuxedo CORBA objects to invoke upon EJBs deployed in WebLogic Server using the RMI-IIOP API.
Configure Local Tuxedo Access Points and Remote Tuxedo Access Points as needed for your environment. No special administration steps are required to enable Tuxedo CORBA objects to invoke upon EJBs deployed in WebLogic Server using the RMI-IIOP API.
For more information on how to configure your WTC Service, see Configuring Oracle WebLogic Tuxedo Connector for Your Applications.
You must perform some additional steps when configuring your Tuxedo application environment.
Set the TOBJADDR for your environment, for example:
//<hostname>:2468
Register WebLogic Server (WLS) Naming Service in the Tuxedo domain's CosNaming namespace by entering the following command:
cnsbind -o ior.txt your_bind_name
where your_bind_name
is the CosNaming service object name from your Tuxedo application.
The ior.txt
file contains the URL of the WebLogic Server's domain Naming Service, for example:
corbaloc:tgiop:myServer/NameService
where myServer
is your server name.
Modify the *DM_REMOTE_SERVICES
of your Tuxedo domain configuration file. Replace your WebLogic Server service name, formerly the DOMAINID
, with the name of your WebLogic Server:
*DM_REMOTE_SERVICES
"//myServer"
where myServer
is the server name that is running the WTC Service.
Load your modified domain configuration file using dmloadcf
.
For more information on how to configure your Tuxedo application environment, see Tuxedo Administration Topics.
This section provides guidelines you need to remember when creating server names that are used as object references.
The maximum field length Tuxedo accepts in the *DM_REMOTE_SERVICES
section is 15 characters including the //. For example: If your server name is examplesServer
, your *DM_REMOTE_SERVICES
object reference is //examplesServe
.
If you require multiple servers, the server names must be unique in the first 13 characters.
You can use the complete name of your server name in the ior.txt
file if it exceeds 13 characters. For example: corbaloc:tgiop:examplesServer/NameService
This section provides information on how to enable WebLogic Server EJBs to invoke upon Tuxedo CORBA objects using the RMI-IIOP API. Use the following steps to modify your WTC Service:
Configure a Local Tuxedo Access Point.
Configure Remote Tuxedo Access Point. Outbound RMI-IIOP requires two additional elements: Federation URL
and Federation Name
.
Set Federation URL
to the URL for a foreign name service that is federated into the JNDI. This must be the same URL used by the EJB to obtain the initial context used to access the remote Tuxedo CORBA object.
Set Federation Name
to the symbolic name of the federation point.
Configure Imported Services.
Set Resource Name
to //domain_id
where domain_id
is DOMAINID
specified in the Tuxedo UBBCONFIG
file of the remote Tuxedo domain where the object is deployed. The maximum length of this unique identifier for CORBA domains is 15 characters including the //
.
Set Local Access Point
to the value of the Local Access Point
attribute of your Remote Tuxedo Access Point.
Set Remote Access Point List
to the value of the Access Point Id
attribute of your Remote Tuxedo Access Point.
For information on how to develop applications that use RMI-IIOP to call a Tuxedo service using a WebLogic Server EJB, see the Oracle Fusion Middleware Tuxedo Connector Programmer's Guide for Oracle WebLogic Server.

The following WTCServer
MBean in the config.xml
file provides an example of a configured WTC Service for outbound RMI-IIOP.
