Administration of CORBA Applications

Note: For more information on CORBA applications, see Tuxedo CORBA.

The following sections provide information on how to administer and configure the WebLogic Tuxedo Connector to support Tuxedo CORBA clients and services.

 


How to Configure WebLogic Tuxedo Connector for CORBA Service Applications

Note: For more information on how to configure your WTC Service, see Configuring WebLogic Tuxedo Connector for Your Applications.

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:

  1. Configure Local Tuxedo Access Points WebLogic Server applications.
  2. Configure Remote Tuxedo Access Points for your Tuxedo CORBA domain.
  3. Configure Imported Services.

For information on how to develop client applications that call a Tuxedo CORBA service using a WebLogic Server EJB, see the WebLogic Tuxedo Connector Programmer's Guide .

Example WTC Service and Tuxedo UBB Files

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.

Listing 4-1 Example WTCServer MBean for a CORBA Server Application
<wtc-server>
     <name>WTCsimpappCNS</name>
     <wtc-local-tux-dom>
          <access-point>examples</access-point>
          <access-point-id>examples</access-point-id>
          <connection-policy>ON_DEMAND</connection-policy>
          <nw-addr>//123.123.123.123:5678</nw-addr>
          <name>myLoclTuxDom</name>
          <security>NONE</security>
     </wtc-local-tux-dom>
     <wtc-remote-tux-dom>
          <access-point>TUXDOM</access-point>
          <access-point-id>TUXDOM</access-point-id>
          <local-access-point>examples</local-access-point>
          <nw-addr>//123.123.123.123:1234</nw-addr>
          <name>myRTuxDom</name>
     </wtc-remote-tux-dom>

          <name>myImportedResources</name>
          <remote-access-point-list>TUXDOM</remote-access-point-list>
          <remote-name>//simpapp</remote-name>
     </wtc-import>
</wtc-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.

How to Administer and Configure WebLogic Tuxedo Connector for Inbound RMI-IIOP

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.

Configuring Your WTC Service for Inbound RMI-IIOP

Note: For more information on how to configure your WTC Service, see Configuring WebLogic Tuxedo Connector for Your Applications.

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.

Administering the Tuxedo Application Environment

Note: For more information on how to configure your Tuxedo application environment, see Tuxedo Administration Topics .

You must perform some additional steps when configuring your Tuxedo application environment.

  1. Set the TOBJADDR for your environment.
  2. Example: //<hostname>:2468

  3. Register WebLogic Server (WLS) Naming Service in the Tuxedo domain's CosNaming namespace by entering the following command:
  4. 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.

Listing 4-3 ior.txt File for iiop.ejb.stateless.server.tux Tuxedo Client Example

corbaloc:tgiop:myServer/NameService

where

myServer is your server name.

  1. 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.
  2. Listing 4-4 Domain Configuration File
    *DM_RESOURCES
         VERSION=U22

    *DM_LOCAL_DOMAINS
         TDOM1 GWGRP=SYS_GRP
         TYPE=TDOMAIN
         DOMAINID="TDOM1"
         BLOCKTIME=20
         MAXDATALEN=56
         MAXRDOM=89

    *DM_REMOTE_DOMAINS
         TDOM2 TYPE=TDOMAIN
         DOMAINID="TDOM2"

    *DM_TDOMAIN
         TDOM1 NWADDR="//123.123.123.123:1234"
         TDOM2 NWADDR="//234.234.234.234:5678"

    *DM_REMOTE_SERVICES
    "//myServer"

where

myServer is the server name that is running the WTC Service.

  1. Load your modified domain configuration file using dmloadcf.

Guidelines About Using Your Server Name as an Object Reference

This section provides guidelines you need to remember when creating server names that are used as object references.

 


How to Configure WebLogic Tuxedo Connector for Outbound RMI-IIOP

Note: For more information on how to configure your WTC Service, see Configuring WebLogic Tuxedo Connector for Your Applications.

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:

  1. Configure a Local Tuxedo Access Point.
  2. Configure Remote Tuxedo Access Point. Outbound RMI-IIOP requires two additional elements: Federation URL and Federation Name.
  1. Configure Imported Services.

For information on how to develop applications that use RMI-IIOP to call a Tuxedo service using a WebLogic Server EJB, see the WebLogic Tuxedo Connector Programmer's Guide.

Example Outbound RMI-IIOP Configuration

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

Listing 4-5 Example WTCServer MBean for Outbound RMI-IIOP
