16.2.5. Assign Bean Pools for Session and Message-Driven Beans

JBoss Administrators can assign individual bean pools for use by session beans and message-driven beans. Bean pools can be assigned by using the Management Console or the CLI tool.
By default two bean pools are provided, slsb-strict-max-pool and mdb-strict-max-pool for stateless session beans and message-driven beans respectively.
To create or edit bean pools, refer to Section 16.2.2, “Create a Bean Pool” and Section 16.2.4, “Edit a Bean Pool”.

Procedure 16.7. Assign Bean Pools for Session and Message-Driven Beans using the Management Console

  1. Login to the Management Console. Section 3.2.2, “Log in to the Management Console”
  2. Navigate to the EJB3 Container Configuration panel.

  3. Click the Edit button. The fields in the Details area are now editable.
  4. Select the bean pool to use for each type of bean from the appropriate combo-box.
  5. Click the Save button to keep the changes, or click the Cancel link to discard them.
  6. The Details area will now be non-editable and display the correct bean pool selection.

Procedure 16.8. Assign Bean Pools for Session and Message-Driven Beans using the CLI

  1. Launch the CLI tool and connect to your server. Refer to Section 3.3.4, “Connect to a Managed Server Instance Using the Management CLI”.
  2. Use the write-attribute operation with the following syntax. 
    /subsystem=ejb3:write-attribute(name="BEANTYPE", value="BEANPOOL")
    • Replace BEANTYPE with default-mdb-instance-pool for Message-Driven Beans or default-slsb-instance-pool for stateless session beans.
    • Replace BEANPOOL with the name of the bean pool to assign.
  3. Use the read-resource operation to confirm the changes. 
    /subsystem=ejb3:read-resource

Example 16.5. Assign a Bean Pool for Session Beans using the CLI

[standalone@localhost:9999 /] /subsystem=ejb3:write-attribute(name="default-slsb-instance-pool", value="LV_SLSB_POOL")  
{"outcome" => "success"}
[standalone@localhost:9999 /]
