Change async-thread-pool size in Teiid

[cesarkuehl]

Hi there!

I'm running Teiid on a Wildfly domain and I'm seeing the message below on every node startup:

[Server:server-two] 16:46:56,411 WARN  [org.teiid.RUNTIME] (Worker7_async-teiid-threads8) TEIID30009 Reached maximum thread count "10" for worker pool "async-teiid-threads" with a queue size high of "5". Queued work waited 8,000 ms prior to executing. To avoid queuing of work you may consider increasing "max-threads" or decreasing the "max-active-plans" in the "standalone-teiid.xml" file.

No matter what value I define to max-threads at standalone-teiid.xml this message still appears at node startup, what makes me think that in a domain mode, this file is simply ignored.

 <async thread-pool-name="default"/>
            <timer-service thread-pool-name="default" default-data-store="default-file-store">
                <data-stores>
                    <file-data-store name="default-file-store" path="timer-service-data" relative-to="jboss.server.data.dir"/>
                </data-stores>
            </timer-service>
            <remote connector-ref="http-remoting-connector" thread-pool-name="default"/>
            <thread-pools>
                <thread-pool name="default">
                    <max-threads count="100"/>
                    <keepalive-time time="100" unit="milliseconds"/>
                </thread-pool>
            </thread-pools>

What is the correct way to raise this thread pool size in a domain?

If you're running in domain mode, then the domain/configuration/domain.xml configuration is where you should be looking.

Also, look at the "ha" profile, as its set as the default.  You can check at the bottom of the file for:  <server-group name="main-server-group" profile="ha">  as to what's its current profile setting.

No matter what I tried to do on domain.xml file, the result was always an error at Wildfly startup, usually saying that it wasn't expecting a parameter at that point.

The only way I found to change this configuration was through the jboss-cli. I issued the following commands and after that I stopped receving the warnings:

/profile=ha/subsystem=teiid:write-attribute(name="async-thread-pool",value="teiid-async")
/profile=ha/subsystem=teiid:write-attribute(name="async-thread-pool-max-thread-count",value="50")

The cli is the preferred way of applying changes to the domain, modifying the domain.xml should be ok when the system is offline - Admin Guide - WildFly 10 - Project Documentation Editor

To add, edit the domain.xml when offline on the "master" node. The configuration in the domain mode is shared across all the nodes.

I noticed that the async-thread-pool-max-thread-count is persisted at domain.xml, and it doesn't change after reboots of the Wildfly. But, the async-thread-pool is not, I can't find it on domain.xml and when I restart Wildfly the value I set at jboss-cli is lost.

Is this a bug or this parameter is persisted elsewhere?

I'm running Wildfly10.0.0.Final with Teiid 9.1.0
