Starting business-level applications
You can start a business-level application that is not
running (has a status of Stopped
). The application
must contain code that can run on a server to start.
Before you begin
The application must be installed on a server. By default, the application starts automatically when the server starts.
About this task
You can start and stop business-level applications manually using the administrative console or wsadmin commands.
This topic describes how to use the administrative console to start a business-level application.
Procedure
Results
A message stating that the application started is displayed.
If the business-level application does not start, ensure that the deployment target to which the application maps is running and try starting the application again.
If an application server on which the application is deployed synchronizes configuration with the deployment manager during server startup, then the application might not start and a DeploymentDescriptorLoadException error might be written to the server SystemErr.log file. Stop and restart the server, and then try starting the application again.
- If SCA composite assets do not start, ensure that each asset is mapped to a Version 8 deployment target or to a Version 7 deployment target that supports SCA composites.
- If an asset composition unit uses an Enterprise JavaBeans (EJB) binding and does not start
because it has a
non-WebSphere target of "null"
, delete the asset composition unit and add it again to the business-level application. Specify a target that supports SCA composites when you add the asset to the business-level application. You cannot change the target after deployment. - If the META-INF/sca-deployables directory
has multiple SCA composite files and the application does not start
because the product
cannot obtain the CompUnitInfoLoader value
, place only the file that contains the composite in the META-INF/sca-deployables directory. You can place the other composite files anywhere else within the archive.
In multiple-node environments, synchronize the nodes after you save changes to the target before starting the business-level application.
What to do next
To restart a running application, select the application you want to restart, click Stop and then click Start.
