Oracle WebLogic Tuxedo Connector Quick Start Guide

Note: For more detailed information on how to configure the Oracle WebLogic Tuxedo Connector for this Oracle WebLogic Server release, see the Oracle WebLogic Tuxedo Connector Administration Guide.

The following sections describe how to use the Oracle WebLogic Server console to configure Oracle WebLogic Tuxedo Connector to allow Oracle WebLogic Server to interoperate with Tuxedo Releases 6.5 and higher:

 

Where to Find Oracle WebLogic Tuxedo Connector Samples

For this release of Oracle WebLogic Tuxedo Connector (WTC), samples are available on the Oracle Technology Network website. Create a wtc directory within the samples directory of your WebLogic Server installation. Download the WTC samples to this directory. To run the samples referenced in this document, you must download the simpapp and simpserv samples.

 

Configuring the Oracle WebLogic Tuxedo Connector

Note: This section summarizes how to configure the Oracle 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 Oracle Tuxedo simpapp application to run over Oracle Tuxedo Domains (TDomains). This allows clients of the TOUPPER service to run on either the Oracle Tuxedo server or the Oracle WebLogic Server examplesServer. The example provides the following services:

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

Build the Simpapp Example

Note: You may want to enable tracing to monitor Oracle WebLogic Tuxedo Connector. See Monitoring the Oracle WebLogic Tuxedo Connector.

Use the following steps to build the simpapp example:

  1. Boot your Oracle WebLogic examplesServer.
  2. Open a new shell window and set environment variables using the SAMPLES_HOME\domains\examples\setExamplesEnv.cmd file.
  3. Change directories to the location where you have downloaded the simpapp sample. For example, SAMPLES_HOME\server\examples\src\examples\wtc\atmi\simpapp directory.
  4. Build the wtc_toupper.jar file using ant. This will deploy the EJB on Oracle WebLogic Server. Enter the following command: ant
  5. Change directories to the location where you have downloaded the simpserv sample. For example, SAMPLES_HOME\server\examples\src\examples\wtc\atmi\simpserv directory.
  6. Build the wtc_tolower.jar file. This will deploy the EJB on Oracle WebLogic Server. Enter the following command: ant
  7. Launch the Administration Console in your browser. Use the following URL: http://your_machine:7001/console. Replace your_machine with the IP address for your machine or your machine name.
  8. In the navigation tree, Click Deployments and confirm that the wtc_tolower.jar and wtc_toupper.jar are deployed.

Create a WTC Service

Use the following steps to create and configure a WTC service using the Oracle WebLogic Server Console:

  4. Click OK.
  5. Your new WTC Service appears in the WTC Servers list.

Create a Local Oracle Tuxedo Access Point

Note: When configuring the Network Address for a local access point, the port number used should be different from any port numbers assigned to other processes. Example: Setting the Network Address to //mymachine:7001 is not valid if the Oracle WebLogic Server listening port is assigned to //mymachine:7001.

  4. Enter the following values for the following fields on the WTC Local Access Points page:

    5. Access Point: myLocalAp

    AccessPoint ID: TDOM2

    Network Address: the network address and port of your local access point

    Example: //123.123.123.123:5678

  5. Click OK.
  6. If you are connecting to a Tuxedo 6.5 domain, do the following:
    1. Click the Connections tab.
    2. Set the Interoperate field to Yes.
    3. Click Save.

Create a Remote Oracle Tuxedo Access Point

Use the following steps to configure a remote Oracle Tuxedo access point:

Configuring Oracle Tuxedo

Use the following steps to configure your Oracle 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 Oracle Tuxedo installation and create a working Oracle Tuxedo simpapp directory.
  3. Change directories to your working Oracle Tuxedo simpapp directory.
  4. Set environment variables using the setEnv.cmd located at TUXDIR. Update the following parameters:

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

  5. Build the clients: 
    6.      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\server\examples\src\examples\wtc\atmi\simpapp directory to your Oracle Tuxedo simpapp directory.
  7. Copy the tolower.c file from the SAMPLES_HOME\server\examples\src\examples\wtc\atmi\simpserv directory to your Oracle Tuxedo simpapp directory.
  8. Modify the ubbdomain for your Oracle 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.

    9. 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 Oracle Tuxedo environment. This includes creating log devices and updating the network addresses.

    11. Example: 

         DMTLOGDEV="d:\my_apps\tlog"
         AUDITLOG="d:\my_apps\aud"
         TDOM1 NWADDR="//TuxedoMachine:1234"
         TDOM2 NWADDR="//WTCMachine:5678"
  11. Load the dom1config file. 
    12.      set BDMCONFIG=d:\mydomain\simpapp\bdmconfig
         dmloadcf -y dom1config
  12. Build the tolower client 
    13.      buildclient -f tolower.c -o tolower
  13. Boot the Tuxedo domain 
    14.      tmboot -y

 

Run the Example

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

Oracle WebLogic Server to Oracle Tuxedo Interoperability

Start an Oracle WebLogic Server client from the directory location to which you downloaded the samples. For example, SAMPLES_HOME\server\examples\src\examples\wtc\atmi\simpapp directory to invoke the TOUPPER EJB and connect to the Oracle Tuxedo TOUPPER service. Use the following command: 

     ant simpapp

The Oracle Tuxedo service replies to your Oracle WebLogic Server application with: 

     Buildfile: build.xml 
     simpapp: 
     run_client:
          [java] Beginning statefulSession.Client... 

          [java] Creating Toupper 

          [java] converting HelloWorld 
          [java] converted to: HELLOWORLD 

          [java] End statefulSession.Client... 

     BUILD SUCCESSFUL

Oracle Tuxedo to Oracle WebLogic Server Interoperability

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

     tolower ALLSMALL

The Oracle WebLogic Server service replies to your Oracle Tuxedo client with: 

     Returned string is: allsmall
