[wildfly-dev] Specifying order of new JGroups Protocol

[Richard Achmatowicz]

Hi Michael

There is no operation for inserting a protocol layer at a specific 
position in the stack.
You will have to remove the original stack definition and recreate it 
with a series of commands.
This can be placed into a CLI batch and executed as a script if you need 
to do it often.
Here is an example:

contents of the CLI script (the following commands in a text file 
called, say, setstack.cli):
--------------------------------------------------------------------------------------
connect
batch
/subsystem=jgroups/stack=tcp:remove()

/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=FDSOCK:add(socket-binding="jgroups-tcp-fd")
/subsystem=jgroups/stack=tcp/protocol=FD:add()
/subsystem=jgroups/stack=tcp/protocol=VERIFY_SUSPECT:add()
/subsystem=jgroups/stack=tcp/protocol=pbcast.NAKACK2:add()
/subsystem=jgroups/stack=tcp/protocol=UNICAST3:add()
/subsystem=jgroups/stack=tcp/protocol=pbcast.STABLE:add()
/subsystem=jgroups/stack=tcp/protocol=pbcast.GMS:add()
/subsystem=jgroups/stack=tcp/protocol=MFC:add()
/subsystem=jgroups/stack=tcp/protocol=FRAG2:add()
run-batch
--------------------------------------------------------------------------------------

execute the CLI script:
./jboss-cli.sh --file=setstack.cli
