Sheng, these two lines where added by you to the file schema-430to440.sql in master but not in 4.4
INSERT INTO `cloud`.`configuration`(category, instance, component, name, value, description, default_value) VALUES ('Advanced', 'DEFAULT', 'NetworkOrchestrationService', 'router.redundant.vrrp.interval', '1', 'seconds between VRRP broadcast. It would 3 times broadcast fail to trigger fail-over mechanism of redundant router', '1') ON DUPLICATE KEY UPDATE category='Advanced'; INSERT INTO `cloud`.`configuration`(category, instance, component, name, value, description, default_value) VALUES ('Advanced', 'DEFAULT', 'NetworkOrchestrationService', 'router.aggregation.command.each.timeout', '3', 'timeout in seconds for each Virtual Router command being aggregated. The final aggregation command timeout would be determined by this timeout * commands counts ', '3') ON DUPLICATE KEY UPDATE category='Advanced'; Is it sensible to add them in 4.4 as well? -- Daan
