How to configure ServerHinting in Infinispan Server?

[mrebasti]

Hello,

It's posible to configure ServerHinting (http://infinispan.org/docs/6.0.x/user_guide/user_guide.html#ServerHinting) in Infinispan Server?

In particular, I'm trying to configure the atributes rackId and siteId in the transport element in this way:

<subsystem xmlns="urn:infinispan:server:core:7.0" default-cache-container="clustered">

            <cache-container name="clustered" default-cache="default">

               <transport rackId="rackA" siteId="siteA" />

               ...

            </cache-container>

  </subsystem>

And I'm getting this error:

Message: JBAS014788: Unexpected attribute 'rackId' encountered

        at org.jboss.as.controller.parsing.ParseUtils.unexpectedAttribute(ParseUtils.java:105) [jboss-as-controller-7.2.0.Final.jar:7.2.0.Final]

        at org.jboss.as.clustering.infinispan.subsystem.InfinispanSubsystemXMLReader_7_0.parseTransport(InfinispanSubsystemXMLReader_7_0.java:192)

        at org.jboss.as.clustering.infinispan.subsystem.InfinispanSubsystemXMLReader_7_0.parseContainer(InfinispanSubsystemXMLReader_7_0.java:132)

This test was made with Infinispan Server 6.0.1 Final and Infinispan Server 7.0.0.Alpha4.

Regards.

It's rack and site, respectively

Galder,

Thanks for the response. The atributes in my example are well placed? With the atribute names rack and site I'm still getting the error:

Message: JBAS014788: Unexpected attribute 'rack' encountered

        at org.jboss.as.controller.parsing.ParseUtils.unexpectedAttribute(ParseUtils.java:105) [jboss-as-controller-7.2.0.Final.jar:7.2.0.Final]

        at org.jboss.as.clustering.infinispan.subsystem.InfinispanSubsystemXMLReader_7_0.parseTransport(InfinispanSubsystemXMLReader_7_0.java:192)

        at org.jboss.as.clustering.infinispan.subsystem.InfinispanSubsystemXMLReader_7_0.parseContainer(InfinispanSubsystemXMLReader_7_0.java:132)

        at org.jboss.as.clustering.infinispan.subsystem.InfinispanSubsystemXMLReader_7_0.readElement(InfinispanSubsystemXMLReader_7_0.java:48)

For what I can see, InfinispanSubsystemXMLReader_7_0.parseTransport isn't expecting any of these atributes. I'm looking the source code here: infinispan/server/integration/infinispan/src/main/java/org/jboss/as/clustering/infinispan/subsystem/InfinispanSubsystemX…

If you look up the file: infinispan-server-7.0.0.Alpha4/docs/schema/jboss-as-jgroups_1_2.xsd you would see the following snippet.

<xs:attribute name="site" type="xs:string">
    <xs:annotation>
        <xs:documentation>Identifies the site where this node runs.</xs:documentation>
    </xs:annotation>
</xs:attribute>
<xs:attribute name="rack" type="xs:string">
    <xs:annotation>
        <xs:documentation>Identifies the rack where this node runs.</xs:documentation>
    </xs:annotation>
</xs:attribute>
<xs:attribute name="machine" type="xs:string">
    <xs:annotation>
        <xs:documentation>Identifies the machine where this node runs.</xs:documentation>
    </xs:annotation>
</xs:attribute>

So essentially you are setting the rack and site attributes in the wrong subsystem, they should go under JGroups subsystem.

Please look the following lines shown here as an example, just to show where all <transport> elements can be defined:

https://github.com/vbchin2/jdg-cross-datacenter-replication/blob/master/configuration/jdg-site-1.xml#L98

https://github.com/vbchin2/jdg-cross-datacenter-replication/blob/master/configuration/jdg-site-1.xml#L155

In conclusion, the rack and site attributes go to transport element of the JGroups configuration.

Thanks! configuring the atributes in the JGroups subsystem works fine.
