Configuring WebSphere Application Server V5.0 for iSeries

This example is for users that are not familiar with the Web serving environment. It describes all the steps necessary to get iSeries™ Access for Web running in a WebSphere^® Application Server V5.0 for iSeries environment. It also describes how to verify that the setup is working. Configuring your Web serving environment consists of these steps:

• Start the IBM^® Web Administration for iSeries interface (also known as IBM HTTP Server for iSeries). See step 1.

• Create an HTTP web server and a WebSphere Application Server V5.0 for iSeries Web application server. See step 2.

• Configure iSeries Access for Web. See step 3.

• Start the web environment. See step 4.

• Use a browser to access iSeries Access for Web. See step 5.

1. Start the IBM Web Administration for iSeries interface.

   1. Start a 5250 session to the system.

   2. Sign on with a user profile that has at least these special authorities:  *ALLOBJ, *IOSYSCFG, *JOBCTL, and *SECADM.

   3. Run the following command to start the web administration interface job: STRTCPSVR SERVER(*HTTP) HTTPSVR(*ADMIN)

   4. Minimize the 5250 session.
2. Create an HTTP web server and a WebSphere Application Server V5.0 for iSeries Web application server:
   1. Open a browser to: http://<system_name>:2001
   2. Log in with a user profile that has, at least these special authorities:  *ALLOBJ, *IOSYSCFG, *JOBCTL, and *SECADM.
   3. Select IBM Web Administration for iSeries.
   4. Select the Setup tabbed page.
   5. Under Common Tasks and Wizards, select Create Application Server.
   6. The Create Application Server page opens. Select Next.
   7. Select WebSphere Application Server V5.0 (base) for iSeries then select Next.
   8. The Specify Application Server Name page opens.   For Application server name, specify iwa50base.  This will be the name of the WebSphere Web application server. Select Next.
   9. The Select HTTP Server Type page opens.  Select Create a new HTTP server (powered by Apache) then select Next.
   10. The Create a new HTTP server (powered by Apache) page opens.

       • For HTTP server name, enter IWA50BASE

       • For Port, specify 2028.
       Select Next.
   11. The Specify Internal Ports Used by the Application Server page opens. For First port in range, change the default value to 21028. Select Next.
   12. The Select Business and Sample Applications page opens. Select Next until the Summary page opens. 
   13. Select Finish.
   14. The web page is re-displayed with the Manage > Application Servers tabbed page active. Under Instance/Server, iwa50base/iwa50base – WAS, V5 (base) is listed with a status of Creating. From this Web page, you can manage the WebSphere application server.

       Use the refresh icon next to the Creating status to refresh the page, if the page does not periodically refresh.

   15. When the status is updated to Stopped, select the green icon next to Stopped to start the WebSphere application server. The status will be updated to Starting. Use the refresh icon next to the Starting status to refresh the page if the page does not periodically refresh. iSeries Access for Web requires that the WebSphere application server is running before it can be configured.

       Wait for the status to be updated to Running before moving to the next step.

   16. Minimize the browser window
3. Configure iSeries Access for Web.
   1. Restore the 5250 session window.
   2. To see the WebSphere application server running, run the command: WRKACTJOB SBS(QEJBAS5)
   3. Verify that IWA50BASE is listed as a job running under the QEJBAS5 subsystem.  iSeries Access for Web requires the WebSphere application server is running before it can be configured.
   4. Verify the Web application server is ready:

      1. Enter option #5 on your IWA50BASE job.

      2. Enter option #10 to display the job log.

      3. Press F10 to display detailed messages.

      4. Verify the message Websphere application server iwa50base ready is listed.  This message indicates that the application server is fully started and is ready for Web serving.

      5. Press F3 until you return to a command line.
   5. iSeries Access for Web provides commands to configure the product. Two different commands are provided, a CL command and a QShell script command.  Both commands provide and perform the same function.  Use whichever version you prefer.

      • To use the CL command, follow these steps:

        1. Configure iSeries Access for Web for your Web application server by using the following command:  

           QIWA2/CFGACCWEB2 APPSVRTYPE(*WAS50) WASINST(iwa50base) 

           These are the parameters used:

           APPSVRTYPE

           Tells the command which Web application server to configure.

           WASINST

           Tells the command which instance of the Web application server to configure.

           For help on this command and the parameters, press F1.
           Migration

           If you are already using iSeries Access for Web within another Web application server, refer to New Web application server considerations. This topic discusses additional CFGACCWEB2 command parameters that can be input to migrate user data from an existing configuration to this new configuration.

        2. Several messages similar to these will be displayed:  

           • Configuring iSeries Access for Web.
