23.2.2. Create a Bean Pool

Bean pools can be created using the Management Console and the CLI tool.
Bean pools can also be created by adding the required bean pool configuration to the server configuration file using a text editor. Example 23.2, “XML Configuration Sample” is an example of what this configuration looks like.

Procedure 23.1. Create a bean pool using the Management Console

  1. Login to the Management Console. Refer to Section 3.4.2, “Log in 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 Bean Pools tab.
  3. Click Add. The Add EJB3 Bean Pools dialog appears.
  4. Specify the required details, Name, Max Pool Size, Timeout value, and Timeout unit.
  5. Click Save button to finish.

Procedure 23.2. Create a bean pool using the CLI

  1. Launch the CLI tool and connect to your server. Refer to Section 3.5.4, “Connect to a Managed Server Instance Using the Management CLI”.
  2. Use the add operation with the following syntax. 
    /subsystem=ejb3/strict-max-bean-instance-pool=BEANPOOLNAME:add(max-pool-size=MAXSIZE, timeout=TIMEOUT, timeout-unit="UNIT")
    • Replace BEANPOOLNAME with the required name for the bean pool.
    • Replace MAXSIZE with the maximum size of the bean pool.
    • Replace TIMEOUT
    • Replace UNIT with the required time unit. Allowed values are: NANOSECONDS, MICROSECONDS, MILLISECONDS, SECONDS, MINUTES, HOURS, and DAYS.
  3. Use the read-resource operation to confirm the creation of the bean pool. 
    /subsystem=ejb3/strict-max-bean-instance-pool=BEANPOOLNAME:read-resource

Example 23.1. Create a Bean Pool using the CLI

[standalone@localhost:9999 /] /subsystem=ejb3/strict-max-bean-instance-pool=ACCTS_BEAN_POOL:add(max-pool-size=500, timeout=5000, timeout-unit="SECONDS")  
{"outcome" => "success"}
[standalone@localhost:9999 /]

Example 23.2. XML Configuration Sample

<subsystem xmlns="urn:jboss:domain:ejb3:1.2">

   <pools>

      <bean-instance-pools>

         <strict-max-pool  name="slsb-strict-max-pool" max-pool-size="20" 
            instance-acquisition-timeout="5" 
            instance-acquisition-timeout-unit="MINUTES" />

         <strict-max-pool name="mdb-strict-max-pool" max-pool-size="20" 
            instance-acquisition-timeout="5" 
            instance-acquisition-timeout-unit="MINUTES" />

      </bean-instance-pools>

   </pools>

</subsystem>
