Caching WSO2 API管理器-添加新网关的最佳方式？

在我们的环境中，我们有几个正在运行的网关（为了安全起见，每个客户端、环境等等）

作为默认配置，这些网关启用了资源缓存（请参阅）

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，就会出现问题。在这种情况下，我们将执行以下操作：

• 为网关分配一台新机器（它们是AWS中的Ubuntu 16.04实例）
• 停止API管理器（在其他计算机上运行）
• 在此api管理器中编辑api-manager.xml，并在“环境”部分中添加新网关
• 启动API管理器
• 尝试在新网关中部署API（我们仅在“发布”选项卡的“网关”部分中检查新网关）

然后我们得到一个错误，因为它试图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。发生此错误后，自然操作是降级到创建的API，并尝试在所有网关中再次发布

在本例中，我们在尝试为以前运行的网关调用服务方法UpdateAppromString时发生了

异常

添加新网关的正确方法是什么？如何清除已损坏的状态？
使用以下代码在Wso2 carbon panel（主机名：9443/carbon url）中添加/更新APILifeCycle。后藤延伸→ 生命周期和编辑/添加生命周期
