Intro

I’m using this new block scheme in Word Press, and I can say: I suck on this. Like totally, I don’t know where do to anything. Totally, is like learning a new language, I know nothing about it. But does not seem that bad, in fact.

OOB Messages

Out Of Band messages – are sent periodically from the members. Is a message with a tag Message.OOB and is processed by a specific thread pool: out-of-band thread pool at the receiver’s side and they are handled at the transport level.

Message msg=new Message();
msg.setFlag(Message.OOB, Message.NO_FC);

Configuration of the oob thread pool:

oob_thread_pool.enabled="true"
oob_thread_pool.min_threads="1"
oob_thread_pool.max_threads="3"
oob_thread_pool.keep_alive_time="60000"
oob_thread_pool.queue_enabled="false"
oob_thread_pool.queue_max_size="500"
oob_thread_pool.rejection_policy="run"/>

getOOBThreadPool
    public Executor getOOBThreadPool()

setOOBThreadPool
    public void setOOBThreadPool(Executor oob_thread_pool)

Removing OOB Thread Pool

For simplicity, JGroups ended up removing OOB Thread Pool, which was combined with the regular thread pool, reducing the number of thread pools in JGroups 4. This means the configuration above, for oob thread pool, becomes obsolete and the new configuration is done as follows:

thread_pool.enabled="true"
thread_pool.min_threads="2"
thread_pool.max_threads="8"
thread_pool.keep_alive_time="5000"
