How to configure EJB Async and EJB Timers to use a separate thread pool in JBoss EAP 7 / 6

Environment

• Red Hat JBoss Enterprise Application Platform (EAP)
  • 7
  • 6

Issue

• How to configure EJB Async and EJB Timers to use a separate thread pool in JBoss EAP 7 / 6
• How to verify the EJB Async thread creation?

Resolution

First, create thread pool for async EJBs to use and configure the async service to use them with these CLI commands:

/subsystem=ejb3/thread-pool=async:add(max-threads=50)
/subsystem=ejb3/service=async:write-attribute(name=thread-pool-name, value=async)

Which changes the JBoss profile xml configuration to:

        <subsystem xmlns="urn:jboss:domain:ejb3:5.0">
            ...
            <async thread-pool-name="async"/>
            <thread-pools>
                ...
                <thread-pool name="async">
                    <max-threads count="50"/>
                </thread-pool>
                ...
            </thread-pools>

To verify the creation, use the command /subsystem=ejb3:read-resource at the jboss-cli and see thread-pool section:

        "thread-pool" => {
            "default" => undefined,
            "async" => undefined
        }

Secondly, create thread pool for EJB timers to use and configure the timer-service to use them with these CLI commands:

/subsystem=ejb3/thread-pool=timer:add(max-threads=30)
/subsystem=ejb3/service=timer-service:write-attribute(name=thread-pool-name,value=timer)

Which changes the JBoss profile xml configuration to:

        <subsystem xmlns="urn:jboss:domain:ejb3:5.0">
            ...
            <timer-service thread-pool-name="timer" default-data-store="default-file-store">
                ...
            </timer-service>
            ...
            <thread-pools>
                ...   
                <thread-pool name="timer">
                    <max-threads count="30"/>
                </thread-pool>
                ...
            </thread-pools>
