WSO2 API 管理器启动时出现“无法添加订阅”错误答案

【问题标题】："Could not add subscription" error when WSO2 API Manager startsWSO2 API 管理器启动时出现“无法添加订阅”错误

【问题描述】：

我有一个 WSO2 API Manager 2.5.0 安装，部署在两个节点中作为主动-主动。它还拥有 WSO2 Analytics 和 WSO2 Identity Server 作为密钥管理器。

每个节点启动时，会在日志中留下三倍相同的错误：

我不知道这个问题。我在网上找过错误，但没有类似的情况。有人有什么想法吗？

您可能已经找到了这个错误的答案。但问题的可能原因是当APIM由于节点之间共享'WSO2_MB_STORE_DB'而无法识别与其自身节点相关的正确主题连接工厂时。

如果您参考他们的Installing and configuring databases 文档，其中提到每个流量管理器节点必须有自己的消息代理数据库(WSO2_MB_STORE_DB)。

因此，请检查两个节点的<APIM_Home>/repository/conf/master-datasource.xml文件下的数据库配置是否在节点之间共享了'WSO2_MB_STORE_DB'。如果是这种情况，您可以将它们指向两个单独的新数据库以消除此错误。
