Setting bind_addr after using -b startup option

[annecotter]

I am using the -b startup option to set the jboss.bind.address

org.jboss.Main.main(new String[] {"-b10.10.1.1"});

Looking at the jboss code, this seems to also set the bind_addr variable used by JGroups.

I want the cluster traffic to use a different address, so I set it in the cluster-service.xml file

<TCP bind_addr="192.168.2.1" start_port="11800" loopback="true" />

However, when I start JBoss the cluster service is binding to the address passed on startup with the -b option (not the one defined in cluster-service.xml)

Any ideas on how to set the bind_addr correctly after using the -b startup option?

Thank you in advance!

You'll need to upgrade your jgroups.jar to version 2.2.8 or later. Then, when you start JBoss, pass in system property ignore.bind.address, e.g.

./run.sh -b 192.168.1.10 -Dignore.bind.address=true

JGroups will check for the system property, and if "true" will ignore the -b switch and use whatever value you set the bind_addr attribute to in your TCP config.

Thank you for the fast response!

Unfortunately, upgrading my version of JGroups is not as easy as it sounds. If you have any suggestions that would work with Jboss 4.0.2/JGroups 2.2.7, it would be much appreciated. (Possibly even another way to define the jboss.bind.address ... setting it using an environment variable or -D doesn't do the trick with 4.0.2)

What happens if you try:

org.jboss.Main.main(new String[] {"-b10.10.1.1", "-Dbind.address=192.168.2.1"});

Be sure the -D comes after the -b. This may not work if the code that processes the args puts the args in a predetermined order. Looking at org.jboss.Main it's not clear if it does or not.

This relies on the fact the for historical reasons JGroups actually uses property bind.address rather than jboss.bind.address. org.jboss.Main sets both properties based on the -b switch. But, if it processes -Dbind.address after it processes -b, then your -D config will override the -b one.

My laptop is bound to 2 networks, and I just tried

run -c all -b 172.31.90.207 -Dbind.address=192.168.90.164

and it worked :-)


run -c all -Dbind.address=192.168.90.164 -b 172.31.90.207

left JGroups bound to 172.31.90.207, so order is important.

That seems to be exactly what I needed, thanks Brian!
