WSO2 API 管理器启动时出现“无法添加订阅”错误

Question

我有一个 WSO2 API Manager 2.5.0 安装，作为主动-主动部署在两个节点中。它还具有 WSO2 分析和 WSO2 身份服务器作为密钥管理器。

每个节点启动时，都会在日志中留下三倍相同的错误：

我不知道这个问题。我在网上找过这个错误，但没有类似的情况。有没有人有任何想法？

您可能已经找到了此错误的答案。但问题的可能原因是，由于节点之间APIM共享“ ”，无法识别与其自身节点相关的正确主题连接工厂。WSO2_MB_STORE_DB

如果您参考他们的安装和配置数据库文档，它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，请检查两个节点的文件下的数据库配置是否在节点之间<APIM_Home>/repository/conf/master-datasource.xml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。
