Configuring the WebLogic Tuxedo Connector

Note: This section summarizes how to configure the WebLogic Tuxedo Connector on a Windows platform. UNIX users can adapt the instructions by making appropriate substitutions such as replacing the "\" with "/" and ".cmd" with ".sh".

This example extends the Tuxedo simpapp application to run over TDomains. This allows clients of the TOUPPER service to run on either Tuxedo or the WebLogic Server examplesServer. The example provides the following services:

• TOUPPER: A Tuxedo service that converts a string to upper case. A WebLogic Server client invokes the TOUPPER EJB and connects to the Tuxedo TOUPPER service.
• Tolower: A service implemented by an EJB in WebLogic Server. The client for the Tolower service runs on Tuxedo.

The following sections describe how to configure WebLogic Tuxedo Connector using the Administration Console:

• Set the TraceLevel
• Build the Simpapp Example
• Create a WTCServer MBean
• Create a Local Tuxedo Domain
• Create a Remote Tuxedo Domain
• Create Exported Services
• Create Imported Services
• Deploy the WTCServer MBean
• Register TDOM1 as a WebLogic Server User

Set the TraceLevel

Note: For more information on TraceLevel, see Monitoring the WebLogic Tuxedo Connector.

TraceLevel is a WebLogic Server Property. Update the JAVA_OPTIONS variable in the SAMPLES_HOME\server\config\examples\startExamplesServer.cmd file. Example:

JAVA_OPTIONS=-Dweblogic.wtc.TraceLevel=100000

where 100,000 specifies the maximum level of WebLogic Tuxedo Connector tracing.

4. Click Create.

Create Imported Services

Use the following steps to configure an imported service:

1. Right-click Imported Services.
2. Select Configure a New WTCImport.
3. Enter the following values for the following fields on the General tab:

   Resource Name: TOUPPER

   Local Access Point: TDOM2

   Remote Access Point List: TDOM1

4. Click Create.

Deploy the WTCServer MBean

Use the following steps to deploy the WTCServer Mbean to examplesServer:

1. Click mySimpapp.
2. Click Targets.
3. Select examplesServer.
4. Click the right-arrow button.
5. Click Apply

Configuring Tuxedo

Use the following steps to configure your Tuxedo domain:

1. Your PATH environment variable needs to include the path of your C compiler. Use set PATH to check the status and add the path if necessary.
2. Copy the simpapp example from your Tuxedo installation and create a working Tuxedo simpapp directory.
3. Change directories to your working Tuxedo simpapp directory.
4. Set environment variables using the setEnv.cmd located at TUXDIR. Update the following parameters:

   TUXDIR - base directory of the TUXEDO Software
   APPDIR - base directory of the sample program

5. Build the clients:

     buildclient -o simpcl -f simpcl.c
     buildserver -o simpserv -f simpserv.c -s TOUPPER

6. Copy the ubbdomain and dom1config files from the SAMPLES_HOME\src\examples\wtc\atmi\simpapp directory to your Tuxedo simpapp directory.
7. Copy the tolower.c file from the SAMPLES_HOME\src\examples\wtc\atmi\simpserv directory to your Tuxedo simpapp directory.
8. Modify the ubbdomain for your Tuxedo environment. This includes setting the pathnames for APPDIR, TUXCONFIG, and TUXDIR and setting the machine name. Replace all <braced> items with information for your environment.

   Example:

     APPDIR="\home\me\simpapp"
     TUXCONFIG="\home\me\simpapp\tuxconfig""
     TUXDIR="\usr\tuxedo" 

9. Load the ubbdomain file: tmloadcf -y ubbdomain
10. Modify the dom1config for your Tuxedo environment. This includes creating log devices and updating the network addresses.

    Example:

     DMTLOGDEV="d:\my_apps\tlog"
     AUDITLOG="d:\my_apps\aud"
     DMTLOGNAME="DMTLOG_TDOM1"
     TDOM1 NWADDR="//TuxedoMachine:1234"
     TDOM2 NWADDR="//WTCMachine:5678"

11. Load the dom1config file.

     set BDMCONFIG=d:\mydomain\simpapp\bdmconfig
     dmloadcf -y dom1config

12. Build the tolower client

     buildclient -v -f tolower.c -o tolower

13. Boot the Tuxedo domain

     tmboot -y

14. Verify all processes have started using the tmadmin psc command.The following domain processes should have booted:

• DMADM, GWADM, and GWTDOMAIN
• The TOUPPER service offered by the simpserv server
• The TOLOWER service is offered by the GWTDOMAIN server

Run the Example

Run each client to demonstrate interoperability between Tuxedo and WebLogic Server.

WebLogic Server to Tuxedo Interoperability

Start a WebLogic Server client from the SAMPLES_HOME\server\src\examples\wtc\atmi\simpapp directory to invoke the TOUPPER EJB and connect to the Tuxedo TOUPPER service. Use the following command:

     run.cmd allcaps

The Tuxedo service replies to your WebLogic Server application with:

     Returned string is: ALLCAPS

Tuxedo to WebLogic Server Interoperability

Run the tolower client from the Tuxedo simpapp directory to invoke the Tolower EJB and return the results to the client. Use the following command:

     tolower ALLSMALL

The WebLogic Server service replies to your Tuxedo client with:

     Returned string is: allsmall
