我正在尝试使用wso2am-analytics-2.1.0和wso2am-2.0.0设置统计信息。根据我在分析和wso2am中配置相同WSO2AM_STATS_DB的文档。当我启动分析服务器时，它给我以下错误。我已经验证了所有以前的帖子，但不知何故无法确定此问题的解决方案。

答案 0 :(得分：4)
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。如果检查分析服务器配置，则在stats-datasources.xml和master-datasources.xml中定义 WSO2AM_STATS_DB 。您无需在master-datasources.xml中定义它。请删除该数据源并启动分析服务器。
