Setting jgroups.bind_address or bind.address in run.conf will be ignored if -b used ----------------------------------------------------------------------------------- Key: JBAS-5581 URL: http://jira.jboss.com/jira/browse/JBAS-5581 Project: JBoss Application Server Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: JBossAS-5.0.0.Beta4, JBossAS-4.2.2.GA Reporter: Galder Zamarreno Assigned To: Galder Zamarreno * Why it it useless specifying -Dbind.address=192.168.0.1 inside run.conf? Why does it work only specifying it on command line? For example: If you set -Dbind.address=127.0.0.1 in run.conf and starting AS with: ./bin/run.sh -b 10.33.144.245 The value assigned to -Dbind.address will be ignored. When you pass -Dbind.address in the command line, JBoss sets both this system property and -Djgroups.bind_address to that value, which means that if you pass -b after that, it won't override the given -Dbind.address. Bottom line, if -Dbind.address set in command line before -b, it's the winner. Example: ./bin/run.sh -Dbind.address=127.0.0.1 -b 1.2.3.4 -> JGroups will bind to 127.0.0.1 If you pass -b in the command line before -Dbind.address, -b will first set -Dbind.address and -Djgroups.bind_address, but then, when -Dbind.address is process, it will override the values of them two with what was passed in -Dbind.address ./bin/run.sh -b 1.2.3.4 -Dbind.address=127.0.0.1 -> JGroups will bind to 127.0.0.1 Now, This does not happen when the -Dbind.address is set in run.conf instead of command line. There's a bug here. When AS processes -b, it checks whether -Dbind.address has been set, which it has, so leaves it as it is. Now, when it checks -Djgroups.bind_address, it sees that it hasn't been set, but *does not do a double check in case -Dbind.address has been set*, so it ends up setting -Djgroups.bind_address to the value of -b, that way ignoring the value you passed to -Dbind.address. Example: run.conf with -Dbind.address=127.0.0.1 ./bin/run.sh -b 1.2.3.4 -> JGroups will bind to 1.2.3.4 What's the fix? Add the double check in -b processing so that if -Dbind.address was set by the user, AS does not take the value of -b and assign to -Djgroups.bind_addr -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
