Manage ABL applications

Deploy ABL application

To deploy 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. On the ABL Applications page, 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 ABL application.
4. Select the ABL Application option as the application type.
5. In the Select Application File field, click Select File to browse to the location of the OpenEdge Archive (OEAR) file containing the ABL application and select the file.
   Note:

   • You can deploy ABL application as an OEAR file only. For information about the OEAR file, see Create an OpenEdge Application Archive using tcman export and Create an OpenEdge Application Archive using an Ant Build.
   • If you are deploying an OEAR file on an instance that already contains ABL applications or web applications with the same names as those included in the OEAR file, you must undeploy the existing applications first.
   • The OEAR file does not need to have the same name as the ABL application.
   • You can upload an OEAR 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.
6. Based on the status of the PAS for OpenEdge instance, 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	Deploy Application dialog box displays	Required action
   Running	The Deploy & Restart button	Click Deploy & Restart.
   Stopped	The Deploy button	Click Deploy.

   Note: The deployment of the ABL application on the PAS for OpenEdge instance is independent of the deployment status of the Apache Tomcat Manager application.
   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 ABL application appears on the ABL Applications page.

   Note: If an ABL application is deployed on a stopped PAS for OpenEdge instance, you must start the instance to access the ABL application services. For information on how to start a PAS for OpenEdge instance, see Start or stop a PAS for OpenEdge instance.

Undeploy ABL application

To undeploy an ABL application from 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 you want to undeploy, and click Actions > Undeploy. The Undeploy ABL Application dialog box appears.
3. Undeploy the ABL application. 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. The following table summarizes different scenarios:

   If		Then
   Status of PAS for OpenEdge instance	Status of Apache Tomcat Manager Application	Undeploy ABL Application 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 click the bell icon to refresh and view the undeployment status. After the successful undeployment, the ABL application no longer appears on the ABL Applications page.
