Upgrade: Review and note the Application Server configuration for Worklight Server and Application Center

In this task, if it is required for the upgrade path, prepare for the undeployment and redeployment of applications to the application server to correct information that can potentially be modified or deleted by IBM Installation Manager.

About this task

In some upgrade scenarios, the applications that are deployed to the application server must be undeployed, and then redeployed. As a consequence, the configurations that were previously made to these applications are erased and must be reconfigured after the application is deployed again to the application server.

The applications to review are as follows:

• For Application Center:

  • The Application Center Console and Application Center Services

• For Worklight Server or MobileFirst Server:

  • The Administration Console and Administration Services

  • Each project runtime

The JDBC data sources to review are as follows:

• For Application Center: the Application Center database

• For Worklight Server or MobileFirst Server:

  • The runtime database

  • The reports database

  • The administration database

If these items were previously configured, note the configuration details so we can reconfigure them after the applications are reinstalled and redeployed. The configurations affected can include security settings, lists of users authorized to use the application, startup behaviors, connection pool settings, JNDI properties, and other items.

The upgrade paths in which this step is mandatory are listed in the following table.

Is this step required for the upgrade path?					System status after this step, if both Application Center and MobileFirst Server are on the same application server
Worklight Server V5.0.6.x to MobileFirst Server v6.3.0	Worklight Server v6.0.x to MobileFirst Server v6.3.0	Worklight Server v6.1.x to MobileFirst Server v6.3.0.x	Worklight Server v6.2.x to MobileFirst Server v6.3.0	v6.3.0 to v6.3.0.x (fix pack or interim fix)	Application Center Status	MobileFirst Server Status
Yes	No (for MobileFirst Server), Yes (for Application Center)	Yes (for both MobileFirst Server and Application Center)	No	See fix pack or interim fix installation instructions	Run	Run

To review the configuration of the data sources and applications:

• For WebSphere Application Server full profile, use the console.

• For WebSphere Application Server Liberty profile:

  • Open the server.xml file. The settings that can be modified or removed by IBM Installation Manager are between the marker comments, as shown in the following sample:

    <!-- Begin of configuration added by IBM Worklight installer. -->
    ...
    <!-- End of configuration added by IBM Worklight installer. -->

• For Apache Tomcat:

  • Open the server.xml and the tomcat-users.xml files. The settings that can be modified or removed by IBM Installation Manager are between the marker comments, as shown in the following sample:

    <!-- Begin of Context and Realm configuration added by IBM Worklight installer. -->
    ...
    <!-- End of Context and Realm configuration added by IBM Worklight installer. -->
