You can manage web applications from the ABL Applications tab by performing the following tasks:
  • Deploy web applications
  • Undeploy web applications

Deploy web application

To deploy a web application into an ABL application on a PAS for OpenEdge instance:

  1. In the OpenEdge Command Center console, click the ABL Applications tab.

    The ABL Applications page appears, listing all ABL applications, web applications, and services deployed across multiple PAS for OpenEdge instances.

  2. Click Actions > Deploy. The Deploy Application dialog box appears.
  3. In the Select PASOE Instance drop-down list, expand the agent node and then select the PAS for OpenEdge instance on which you want to deploy the web application.
  4. Select the Web Application option as the application type.
  5. In the Select ABL Application field, type a new ABL application name or select the existing one from the drop-down list.
    Note: If you type a new ABL application name, an ABL application with that name will be created and the web application will be deployed into it.
  6. In the Select Application File field, click Select File to browse to the location of the WAR file containing the web application and select the file.
    Note:
    • If you are deploying a WAR file into an ABL application that already contains web applications with the same names as those included in the WAR file, you must undeploy the existing applications first.
    • You can upload a WAR file only if its size is less than or equal to 523,239,424 bytes (499 MB). If you want to upload a larger file, update the system-config.json file by adding the maxFileUploadSize parameter with appropriate value and restart the OpenEdge Command Center server. The maximum value you can set is 3,221,225,472 bytes (3 GB). For more information, see OpenEdge Command Center server configuration.
  7. In the Web Application Name field, type the name of the web application.
    Note: The web application name is automatically detected from the WAR file and is displayed in the Web Application Name field by default. You can change the application name if needed.
  8. Based on the status of the PAS for OpenEdge instance and deployment of the Apache Tomcat Manager application, the dialog box displays either the Deploy or Deploy & Restart button. The following table summarizes different scenarios:
    If Then
    Status of PAS for OpenEdge instance Status of Apache Tomcat Manager Application Deploy Application dialog box displays Required action
    Running Deployed The Enter Apache Tomcat Manager credentials section and the Deploy button Enter the credentials and click Deploy.
    Running Not deployed The Deploy & Restart button Click Deploy & Restart.
    Stopped NA The Deploy button Click Deploy.
    Note: If you enter the incorrect Manager credentials, the application deployment becomes a normal deployment and requires the PAS for OpenEdge instance to restart.
    A popup window appears, displaying the notification that the deploy operation is successfully submitted. You can click the bell icon to refresh and view the deployment status. After the successful deployment, the web application appears in the Web Application pane when you select the corresponding ABL application.

Undeploy web application

To undeploy a web application from an ABL application on a PAS for OpenEdge instance:

  1. In the OpenEdge Command Center console, click the ABL Applications tab.

    The ABL Applications page appears, listing all ABL applications, web applications, and services deployed across multiple PAS for OpenEdge instances.

  2. Select the ABL application that contains the web application you want to undeploy. The associated web applications appear in the Web Applications pane.
  3. Locate the card for the web application that you want to undeploy and then click Undeploy on the card. The Undeploy Web Applications dialog box appears.
  4. Based on the status of the PAS for OpenEdge instance and deployment of the Apache Tomcat Manager application, the dialog box displays either the Undeploy or Undeploy & Restart button:
    If Then
    Status of PAS for OpenEdge instance Status of Apache Tomcat Manager Application Undeploy Web Applications dialog box displays Required action
    Running Deployed The Enter Apache Tomcat Manager credentials section and the Undeploy button Enter the credentials and click Undeploy.
    Running Not deployed The Undeploy & Restart button Click Undeploy & Restart.
    Stopped NA The Undeploy button Click Undeploy.
    A popup window appears, displaying the notification that the undeploy operation is successfully submitted. You can the bell icon to refresh and view the undeployment status. After the successful undeployment, the web application no longer appears in the Web Applications pane.
