IBM WebSphere Application Server Plugin Reference 8.6.x

The IBM WebSphere Application Server (WAS) plugin adds capability for managing deployments and resources on an existing WebSphere application server.

This document provides information that is specific to this version of the WAS plugin. For general information about the plugin, refer to Introduction to the XL Deploy WebSphere Application Server plugin.

Requirements

• All WAS plugin versions before 8.6.0 support XL Deploy 5.1.0 or later
• WAS plugin 8.6.0 and later require XL Deploy 8.5.0 or later
• IBM WebSphere Application Server Standard and Network Deployment 7.0, 8.0, 8.5 or 9.0 (Unix and Microsoft Windows)

Limitations

1. Due to presence of a UTF-8 encoding issue in WAS 9.0, the values of non-English characters such as á, Á, é, É, ú, Ý, and so on are not displayed correctly in the WAS console.

Using the deployables and deployeds

The following table shows the possible containers a deployable can be targeted to and the deployed that will be created as a result.

Deployable vs. containers table

Deployed actions table

The following table shows the actions taken when creating, modifying, or destroying a deployed.

Migrating from WAS plugin extensions

From version 4.5.0, the functionality of the WAS plugin extensions has been incorporated in the official WAS plugin. Version 4.5.0 of was-plugin-extensions exists for backwards compatibility only. Please port all your CIs to the WAS plugin, since this will be the only supported WAS plugin from now on.

The majority of the CIs can be ported by substituting the wasx prefix for was.

The following table shows the exceptions to this pattern:

Migrated type-modifications

Type-modifications previously present in the extensions plugin will be automatically upgraded to new state according to the following transition table:

Possible breaking changes / different behavior

Overwrite behavior

Take notice that existing values of complex properties (i.e. JVM args, Environment vars etc.) will by default be overwritten by values specified in XL Deploy CIs. If the existing values on WebSphere are to be preserved, please remember to include them in XL Deploy CIs prior to deployment.

If a CI property is not explicitly set, XL Deploy will use its default value. If a default value is not defined, an empty value will be sent to the WebSphere Application Server.

On CIs extending was.ConfigurationResource this behaviour can be overridden by setting the values of properties overwriteExistingValues and overwriteExistingCustomProperties to false.

When overwriteExistingValues is set to false, only the provided properties will be set; properties not specified in the deployed CI will be left as-is. Please note here that properties with default values still take effect and will be considered as set on the deployed CI!

Property overwriteExistingCustomProperties changes the MODIFY behaviour of complex properties (i.e. JVM args, Environment vars etc.) once user has defined at least one entry on the complex property. When set to false, existing entries present on the server will be left as is and new entries will be appended to the existing custom properties. If server already has an entry (property) of the same name, its value will be updated.

Managed server control task

was.ManagedServer doesn't have property "template". Instead, this control tasks accepts parameter of type was.ManagedServer_create. One can invoke control tasks from cli using following snippet:

newServerId='Infrastructure/localhost/vagrantCell01/vagrantNode01/test3'
newServer = factory.configurationItem(newServerId, 'was.ManagedServer', {'serverType': 'APPLICATION_SERVER', 'tags' : ['scope_jvm'] });
repository.create(newServer)
control = deployit.prepareControlTask(newServer, "create")
control.parameters.values['template'] = 'default'
taskId = deployit.createControlTask(control)
deployit.startTaskAndWait(taskId)

Container Restart Strategy property implementation at container level

When the containerRestartStrategy property is set to STOP_START or RESTART on was.Module, this value will take precedence over the value that is set on the WebSphere application servers and clusters.

If the containerRestartStrategy property is set to NONE on was.Module and is set to STOP_START or RESTART in was.ManagedServer, was.UnmanagedServer, or was.Cluster (that is, on the container level), then the value that is set on the container level will be applied to the respective containers.

Character encoding

If non-ASCII characters appear garbled on the WebSphere Application Server (WAS) Admin Console, verify that the default shell on the host with the deployment manager is correctly configured for UTF-8 character encoding; that is, a locales package is installed, the UTF-8 locale is generated, and the LC_ALL, LANG, and LANGUAGE environmental variables are configured with the correct value (en_US.UTF-8).

Possible breaking changes / different behavior

This plugin version requires XL Deploy 4.0.1+

Take notice that existing values of complex properties (i.e. JVM args, Environment vars etc.) will by default be overwritten by values specified in XL Deploy CIs. If the existing values on WebSphere are to be preserved, please remember to include them in XL Deploy CIs prior to deployment.

If a CI property is not explicitly set, XL Deploy will use its default value. If a default value is not defined, an empty value will be sent to the WebSphere Application Server.

Type changes

Application resources

The was.Ear, was.War and was.EjbJar CIs have been extended with additional properties to support configuration of class loading, JSP compilation/reloading, security mappings and other.

In order to support configuration of properties on a specific module contained by a was.Ear artifact, new embedded types have been introduced into the hierarchy: was.EmbeddedWebModule and was.EmbeddedEjbModule.

To ensure backwards compatibility with previous versions, all properties (i.e. webServers, virtualHost, sharedLibraries, webClassLoaderMode) are still available on the was.Ear type. When used, those properties will be propagated to all modules inside an Enterprise Application Archive. To override the top-level EAR settings, specify an embedded module CI and set the module specific properties.

Properties configurable on the module level are:

For usage scenario, please see the following deployment package:

<udm.DeploymentPackage version="1.0" application="myapp">
  <deployables>
    <was.Ear name="myapp-ear" file="myapp-ear/myapp-1.0.5.ear">
      <virtualHostName>default_host</virtualHostName>

              <resourceJndiName>ejb/ConverterBean</resourceJndiName>
            </was.EjbRefSpec>
          </ejbRefs>
          <resourceRefs>
            <was.ResourceRefSpec name="myapp-ear/myappWeb.war/jdbcmyappdb">
              <resourceRefName>jdbc/myapp_db</resourceRefName>

              <resourceJndiName>jdbc/myapp_db_xa</resourceJndiName>
            </was.ResourceRefSpec>
          </resourceRefs>
        </was.EmbeddedWebModuleSpec>
      </webModules>
      <ejbModules>
        <was.EmbeddedEjbModuleSpec name="myapp-ear/myappEJB.jar">

        </was.EmbeddedEjbModuleSpec>
      </ejbModules>
    </was.Ear>
  </deployables>
</udm.DeploymentPackage>

Name of the embedded module should correspond to the WAR or EJB module file name. If this is not possible, additional uri and displayName properties can be set. E.g.:

<was.EmbeddedEjbModuleSpec name="myapp-ear/myapp-ejb">
  <startingWeight>20</startingWeight>
  <uri>myappEJB.jar,META-INF/ejb-jar.xml</uri>
  <moduleDisplayName>myappEJB</moduleDisplayName>
</was.EmbeddedEjbModuleSpec>

JMS resources

New intermediate virtual types have been introduced into the WMQ ConnectionFactory, Destination and Generic ConnectionFactory CI hierarchy and now corresponds the following:

was.JmsResource | <- was.JmsConnectionFactory | <- was.WmqConnectionFactory | <- was.WmqQueueConnectionFactory
                |                             |                             | <- was.WmqTopicConnectionFactory
                |                             |
                |                             | <- was.GenericJmsConnectionFactory | <- was.GenericJmsQueueConnectionFactory
                |                                                                  | <- was.GenericJmsTopicConnectionFactory
                |
                | <- was.WmqDestination | <- was.WmqQueue

• [DEPL-5221] - Duplicate shared library check is too broad

Possible breaking changes / different behavior

The various data source, JDBC provider and JAAS alias scripts were made idempotent. This means they will be more robust against objects already being created. Objects found will be made to look according to what is specified in XL Deploy. If you have local changes to the scripts for these types you will have to verify if your changes are still necessary or work.

A JAAS alias will now be propagated to runtime in an additional step. No server restart needed. This behaviour also applies to data sources were a username and password is specified (and a JAAS alias is created under the hood). As a result the test connection functionality will now work with a newly deployed JAAS alias.

A JAAS alias generated by was.JaasAlias or was.DataSources will now always target Global Security. Previously it would fail if multiple Security objects existed.

Compared to the wasx.ListenerPort type the was.ListenerPort does not support deploying to a Cluster.
