Wildfly CLI - jgroups

dominique_claes Dec 1, 2016 5:02 AM

Hello,

I'm able to use Wildfly CLI to add a socket-binding for jgroups but I'm unable to add the default jgroups subsystem configuration as found in standalone-ha.xml by use of CLI.

How can I add the following configuration by CLI:

<subsystem xmlns="urn:jboss:domain:jgroups:4.0">
            <channels default="ee">
                <channel name="ee" stack="udp"/>
            </channels>
            <stacks>
                <stack name="udp">
                    <transport type="UDP" socket-binding="jgroups-udp"/>
                    <protocol type="PING"/>
                    <protocol type="MERGE3"/>
                    <protocol type="FD_SOCK" socket-binding="jgroups-udp-fd"/>
                    <protocol type="FD_ALL"/>
                    <protocol type="VERIFY_SUSPECT"/>
                    <protocol type="pbcast.NAKACK2"/>
                    <protocol type="UNICAST3"/>
                    <protocol type="pbcast.STABLE"/>
                    <protocol type="pbcast.GMS"/>
                    <protocol type="UFC"/>
                    <protocol type="MFC"/>
                    <protocol type="FRAG2"/>
                </stack>
                <stack name="tcp">
                    <transport type="TCP" socket-binding="jgroups-tcp"/>
                    <protocol type="MPING" socket-binding="jgroups-mping"/>
                    <protocol type="MERGE3"/>
                    <protocol type="FD_SOCK" socket-binding="jgroups-tcp-fd"/>
                    <protocol type="FD"/>
                    <protocol type="VERIFY_SUSPECT"/>
                    <protocol type="pbcast.NAKACK2"/>
                    <protocol type="UNICAST3"/>
                    <protocol type="pbcast.STABLE"/>
                    <protocol type="pbcast.GMS"/>
                    <protocol type="MFC"/>
                    <protocol type="FRAG2"/>
                </stack>
            </stacks>
        </subsystem>

Something like this:

batch
/subsystem=jgroups:add(default-channel=ee)
/subsystem=jgroups/channel=ee:add(stack=udp)
/subsystem=jgroups/stack=udp:add()
/subsystem=jgroups/stack=udp/transport=UDP:add(socket-binding=jgroups-udp)
/subsystem=jgroups/stack=udp/protocol=PING:add()

The following works: jboss-cli.sh --connect command="/subsystem=jgroups:add(default-channel=ee,default-stack=udp)"

But the next command fails: .jboss-cli.sh --connect command="/subsystem=jgroups/channel=ee:add"
Then I get the message:

{
    "outcome" => "failed",
    "failure-description" => "WFLYCTL0216: Management resource '[
    (\"subsystem\" => \"jgroups\"),
    (\"stack\" => \"udp\")
]' not found",
    "rolled-back" => true
}

Even when I run it in batch, it fails

dominique_claes My apologies - I was a little tired when I originally responded. I've edited the above batch of commands for correctness.

You *must* execute the above commands as a batch, otherwise they would need to be ordered carefully to prevent resources being referenced before they are defined. Also, don't use default-stack, it is deprecated.

The following equivalent set of commands will be runnable without a batch:

/subsystem=jgroups:add()
/subsystem=jgroups/stack=udp:add()
/subsystem=jgroups/stack=udp/transport=UDP:add(socket-binding=jgroups-udp)
/subsystem=jgroups/stack=udp/protocol=PING:add()
/subsystem=jgroups/stack=udp/protocol=MERGE3:add()
/subsystem=jgroups/stack=udp/protocol=FD_SOCK:add(socket-binding=jgroups-udp-fd)
/subsystem=jgroups/stack=udp/protocol=FD_ALL:add()
/subsystem=jgroups/stack=udp/protocol=VERIFY_SUSPECT:add()
/subsystem=jgroups/stack=udp/protocol=pbcast.NAKACK2:add()
/subsystem=jgroups/stack=udp/protocol=UNICAST3:add()
/subsystem=jgroups/stack=udp/protocol=pbcast.STABLE:add()
/subsystem=jgroups/stack=udp/protocol=pbcast.GMS:add()
/subsystem=jgroups/stack=udp/protocol=UFC:add()
/subsystem=jgroups/stack=udp/protocol=MFC:add()
/subsystem=jgroups/stack=udp/protocol=FRAG2:add()
/subsystem=jgroups/stack=tcp:add()
/subsystem=jgroups/stack=tcp/transport=TCP:add(socket-binding=jgroups-tcp)
/subsystem=jgroups/stack=tcp/protocol=MPING:add(socket-binding=jgroups-mping)
/subsystem=jgroups/stack=tcp/protocol=MERGE3:add()
/subsystem=jgroups/stack=tcp/protocol=FD_SOCK:add(socket-binding=jgroups-udp-fd)

Sadly it fails. When I implement the commands from above, I get the following message:

{
    "outcome" => "failed",
    "failure-description" => "WFLYCLJG0010: Transport for stack udp is not defined. Please specify both a transport and protocol list, either as optional parameters to add() or via batching.",
    "rolled-back" => true,
    "response-headers" => {"process-state" => "reload-required"}
}

I believe it fails with command: "/subsystem=jgroups/stack=udp:add()"

dominique_claes The batch-less commands I posted will only work in admin-only mode. If you are trying to run these commands against a runtime server, then you need to batch them.

Hi Paul,

Still no result. It still gives the error from the previous post.

Are you certain that you are batching them correctly?

When I create a separate file with all the commands in batch and I execute that script in 'embed-server' mode than it works.
It was like you suggested that I needed to run this while Wildfly is not running.
