Monitored Deployment/Auto-deployment

In WebSphere Application Server v8, you can specify a deployment directory location which websphere
can monitor and do deployments.
Monitored Directory
Monitor Directory specifies whether to enable monitored directory deployment. You can use monitored
directory deployment to install or update an enterprise application file on an application server or cluster,
or to uninstall an application file that was previously installed using monitored directory deployment. You
can install or update an application file by dragging or copying an EAR, WAR, JAR, SAR to a monitored
directory. The application file must conform to the Java Platform, Enterprise Edition (Java EE)
specification. To uninstall a deployed application file, remove it from the monitored directory.
This sound like the „webapps‟ directory of the tomcat server to me, at this moment. Now, let us see how it
works.
Settings
By default, this option is disabled. To enable, go to Applications –>Global Deployment Settings
1. Monitor Directory to automatically deploy application – must select to enable the option.
2. Monitored Directory – Directory where you will place your deploy-able files and websphere should
monitor
For base (stand-alone) application servers, the default monitored directory is the
monitoredDeployableApps/servers/server_name directory of the application server
profile.
For deployment managers, the
default monitored
directories
monitoredDeployableApps/servers/server_name,
monitoredDeployableApps/nodes/node_name/servers/server_name,

are
the

and monitoredDeployableApps/clusters/cluster_name directories of the deployment
manager profile.
3. Polling interval – Specifies the number of seconds that elapse before the WebSphere scans a
monitored directory for new applications. Default is 5 seconds.
4. Click apply, save change and restart server [ before restart nothing happened in the monitored
directory ]

For base (stand-alone) application servers, the default monitored directory is the
monitoredDeployableApps/servers/server_name directory of the application server profile.

For

managers,

are
the
deployment
I‟ve changed the Monitored directory to {USER_INSTALL_ROOT}/Autodeploy. Created „AutoDeploy‟
directory under C:/IBM/WWebSphere8/profiles/AppServer01 [this is my USER_INSTALL_ROOT]. then
restarted server. Now i can see 2 new directories under {USER_INSTALL_ROOT}/Autodeploy with
names deployment properties and Servers. Under servers directory i‟ve another directory with name
server1 which is actually my server name. So the directory that is now being monitored by WebSphere is
”{USER_INSTALL_ROOT}/Autodeploy/servers/server1“
Deployment
Ok.. Now let’s do a deployment. for the testing purpose i took cachemonitor.war from „installableApps‟
and
placed
it
in
the
monitored
directory.
After 5 seconds.. i can see the following update in my SystemOut.log

[4/25/11 11:59:49:538 PDT] 00000023 InstallSchedu I ADMA5013I: Application Dynamic Cache
Monitor installed successfully.
This clearly says that the deployment is successful. Now go to Applications –> Application Types –>
websphere enterprise applications in the admin console. I can see the dynamic cache monitor deployed
ans started successfully. Another thing i noticed here is it generated [updated] the plugin-cfg.xml and
propagated it to my Web Server [IHS].
UnDeployment
Now that deployment is successful.. Let’s test the UnDeployment. Just remove the application EAR file
from monitored directory and wait for 5 sec [polling interval]

Uninstalling application Dynamic Cache Monitor…
[4/25/11 12:07:00:143 PDT] 00000022 AppBinaryProc I ADMA7021I: Distribution of application
Dynamic Cache Monitor completed successfully.
It was successfully uninstalled and again updated and propagated my plugin configuration accordingly.
Final comments:
It is really simple and works well. I liked the plugin configuration update part. Since i‟m working on
Base/Beta version, we have restrictions on the clusters, LB etc.. It would be interesting to see the
deployment on the clusters.
Next Steps:
Try and use the „deploymentProperties‟ file to customize the deployments, updates, undeployments.
