21.6. Configuring the EJB3 Timer Service

Procedure 21.21. Configure the EJB3 Timer Service Thread Pool via the Management Console

1. Login to the Management Console.
2. Click on the Configuration tab at the top of the screen. Expand the Container menu and select EJB 3. Select the Services tab, click on Timer Service. Click Edit.
3. Click on the EJB3 Thread Pool drop-down list and click on the preferred thread pool's name.
4. Restart the JBoss EAP instance.

Procedure 21.22. Configure the EJB3 Timer Service Thread Pool via the Management CLI

1. Run the following Management CLI command.

   /subsystem=ejb3/service=timer-service:write-attribute(name=thread-pool-name,value="thread-pool-name")

2. Restart the JBoss EAP instance.

Procedure 21.23. Configure the EJB3 Timer Service Directory via the Management Console

1. Login to the Management Console.
2. Click on the Configuration tab at the top of the screen. Expand the Container menu and select EJB 3. Select the Services tab, click on Timer Service. Click Edit.
3. Enter your desired values into the Path and Relative To fields.
4. Click Save.
5. Restart the JBoss EAP instance.

Procedure 21.24. Configure the EJB3 Timer Service Directory via the Management CLI

1. Depending on which paths you want to change, run one or both of the following Management CLI commands. For either path you can use a system value - for example, ${jboss.server.data.dir}.

   Note

   Add the prefix /profile=PROFILE_NAME to the command for a managed domain.

   /subsystem=ejb3/service=timer-service/file-data-store=default-file-store:write-attribute(name=path,value="path")

   /subsystem=ejb3/service=timer-service/file-data-store=default-file-store:write-attribute(name=relative-to,value="relative-path")

2. Restart the JBoss EAP instance.

Procedure 21.25. Configure the EJB3 Timer Service to use a Datasource via the Management CLI

• Run the following Management CLI command.
  • datastore_name - A name of your choice.
  • datasource_name - The name of the datasource to be used for storage.
  • database - either postgresql, mssql, sybase, mysql, oracle, db2, or hsql.
  • partition_name - A name of your choice. This attribute is used to distinguish timers pertaining to a particular server instance if multiple JBoss EAP instances share the same database for storing EJB timers. In this case, every server instance should have its own partition name. If the database is used by only one server instance, you can leave this attribute blank.

  /subsystem=ejb3/service=timer-service/database-data-store=datastore_name:add(datasource-jndi-name='java:/datasource_name', database='database', partition='partition_name')

Procedure 21.26.  Configure one or all EJB3 Deployments to use the Datasource

• • To configure an EJB3 deployment to use the datasource, edit the jboss-ejb3.xml of the deployment so the timer section looks as follows. Replace datastore_name with the name of the datastore.

    [<assembly-descriptor>
      <timer:timer>
        <ejb-name>*</ejb-name>
        <timer:persistence-store-name>datastore_name</timer:persistence-store-name>
      </timer:timer>
    </assembly-descriptor>

  • To configure the datasource as the default for all deployments, run the following Management CLI command, then restart the JBoss EAP instance. Replace datastore_name with the name of the datastore.

    Note

    Add the prefix /profile=PROFILE_NAME to the command for a managed domain.

    [/subsystem=ejb3/service=timer-service:write-attribute(name=default-data-store,value=datastore_name)
