【中文标题】带有 Analytics 的 WSO2 API 管理器：stats-datasources.xml\' - 系统数据源 WSO2AM_STATS_DB 无法更新

【英文标题】：WSO2 API Manager with Analytics: stats-datasources.xml' - System datasource WSO2AM_STATS_DBcan not be updated带有 Analytics 的 WSO2 API 管理器：stats-datasources.xml' - 系统数据源 WSO2AM_STATS_DB 无法更新

【问题描述】：

我正在尝试使用 wso2am-analytics-2.1.0 和 wso2am-2.0.0 设置统计信息。根据文档，我也在分析和 wso2am 中配置了相同的 WSO2AM_STATS_DB。当我启动分析服务器时，它给了我以下错误。我已经验证了所有以前的帖子，但不知何故无法找出这个问题的解决方案。

【参考方案1】：

如果您在服务器配置中多次定义了相同的数据源，则可能会发生此错误。如果您检查分析服务器配置 WSO2AM_STATS_DB 是在 stats-datasources.xml 以及 master-datasources.xml 中定义的。您不需要在 master-datasources.xml 中定义它。请删除该数据源并启动分析服务器。

【讨论】：

有人有解决办法吗？
