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
- Go
to the Business-level applications page.
Click in
the console navigation tree.
- Select the
check box for the application you want started.
- Click Start.
The
product runs the application and changes the state of the application
to Started. The status is changed to partially
started if not all servers on which the application is deployed
are running.
Results
A message stating
that the application started displays
at the top the page.
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.
New feature: This topic
references one or more of the application server log files. Beginning
in WebSphere Application Server Version 8.0 you can configure the
server to use the High Performance Extensible Logging (HPEL) log and
trace infrastructure instead of using
SystemOut.log ,
SystemErr.log,
trace.log, and
activity.log files or native z/OS logging
facilities. If you are using HPEL, you can access all of your log
and trace information using the LogViewer command-line tool from your
server profile bin directory. See the information about using HPEL
to troubleshoot applications for more information on using HPEL.
newfeat
If
the application contains Service Component Architecture (SCA) composites
and does not start, check for the following problems:
- 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.
What to do next
To restart a running
application, select the application
you want to restart, click Stop and then click Start.
