在我们的环境中,我们有几个网关运行(出于安全目的,为每个客户端,环境等)。
这些网关启用了资源缓存,作为默认配置(请参阅Configuring caching)
当我们必须添加新网关(例如,新客户)并尝试将已发布的API部署到新网关时,我们的问题就出现了。在这种情况下,我们执行以下操作:
然后我们收到错误,因为它尝试重新创建以前存在的缓存
TID: [-1234] [] [2018-04-19 16:53:35,698] ERROR {org.wso2.carbon.governance.registry.extensions.aspects.DefaultLifeCycle} - org.wso2.carbon.registry.core.exceptions.RegistryException: Execution failed for action : Publish Embedded error : FaultGatewaysException:{"PUBLISHED":{"Prototype":"Error while updating API in the gateway.

这是我们的网关配置

更糟糕的是。出现此错误后,自然操作是降级为CREATED API,并尝试在所有网关中再次发布。
在这种情况下,我们先前运行的网关出现Exception occurred while trying to invoke service method updateApiFromString
错误
添加新网关的正确方法是什么?而且,我该如何清理损坏的状态呢?
答案 0 :(得分:1)
使用以下代码在Wso2碳面板(主机名:9443 / carbon url)中添加/更新APILifeCycle。转到扩展→生命周期,然后编辑/添加APILifeCycle。
