Export applications using wsadmin.sh

We can export the applications before you update installed applications or before you migrate to a different version of the product.

The application whose contents you want to export is installed on a server.

We can use the com.ibm.websphere.management.application.client.EnvEntry_processBindings JVM custom property to specify how an environment entry value is handled during an application deployment. However:

• If an application is deployed with com.ibm.websphere.management.application.client.EnvEntry_processBindings enabled and is then exported to be deployed on a pre-Version 8.0 environment, the environment entry value in the XML bindings are not recognized by both the deployment and runtime environments.

• If an application is deployed with com.ibm.websphere.management.application.client.EnvEntry_processBindings enabled and is then exported to be deployed on a Version 8.0 or 8.0.0.1 environment, the environment entry value in XML bindings are not be recognized by the deployment environment but are recognized by the runtime environment.

gotcha

Exporting applications allows us to back them up and preserve their binding information.

Tasks

1. Start the wsadmin scripting tool.
2. Export applications.
   • Export an enterprise application to a location of your choice, for example:
     • Jacl:

       $AdminApp export app1 /mystuff/exported.ear
       

     • Jython:

       AdminApp.export('app1', '/mystuff/exported.ear')
       

       Element	Description
       $	is a Jacl operator for substituting a variable name with its value
       AdminApp	is an object allowing application objects management
       export	is an AdminApp command
       app1	is the name of the application that will be exported
       /mystuff/exported.ear	is the name of the file where the exported application will be stored

   • Export Data Definition Language (DDL) files in the enterprise bean module of an application to a destination directory, for example:
     • Jacl:

       $AdminApp exportDDL app1 /mystuff
       

     • Jython:

       AdminApp.exportDDL('app1', '/mystuff')  
       

     Element	Description
     $	is a Jacl operator for substituting a variable name with its value
     AdminApp	is an object allowing application objects management
     exportDDL	is an AdminApp command
     app1	is the name of the application whose DDL files will be exported
     /mystuff	is the name of the directory where the DDL files export from the application
