Description
Scenario: we have a 4 nodes EAP cluster where we deploy an EAR where the jboss-all.xml deployment descriptor is used to define the EAR as a singleton deployment;
We observe a higher fail rate (~7.7%) than when we use the other option for the deployment descriptor: the singleton-deployment.xml (~3.1%).
<?xml version="1.0" encoding="UTF-8"?>
<jboss xmlns="urn:jboss:1.0">
<singleton-deployment xmlns="urn:jboss:singleton-deployment:1.0"/>
</jboss>
<?xml version="1.0" encoding="UTF-8"?> <singleton-deployment xmlns="urn:jboss:singleton-deployment:1.0"/>
Find attached the two EAR deplyed.
The cli script used to configure the server, in both cases, is the following:
embed-server --server-config=standalone-ha.xml /subsystem=singleton/singleton-policy=default/election-policy=random:add() /subsystem=jgroups:write-attribute(name=default-stack,value=tcp) /subsystem=jgroups/channel=ee:write-attribute(name=stack,value=tcp)
