oracle - WSO2 DAS 3.0.0 与 API Manager 1.9.0 无法正常工作

Question

我正在尝试使用 DAS 3.0.0 来替换 BAM 以及 WSO2 API Manager 1.9.0/1.9.1 和 Oracle for WSO2AM_STATS_DB。

我正在关注http://blog.rukspot.com/2015/09/publishing-apim-runtime-statistics-to.html

我可以在数据浏览器表 ORG_WSO2_APIMGT_STATISTICS_REQUEST 和 ORG_WSO2_APIMGT_STATISTICS_RESPONSE 中查看 DAS 碳仪表板中的数据。

但是数据并不存储在Oracle中。因此我无法在 AM 的出版商中看到统计信息。一直显示“已启用数据发布。生成一些流量以查看统计信息。”

我在日志中收到以下错误:

我错过了什么吗？谁能帮我解决这个问题吗？

提前致谢。

将所有库(jar)移至项目的/WEB-INF/lib 中。现在/WEB-INF/lib 下的所有库/jar 都将位于类路径下。

使用 snappy-java jar 文件，它会按照你想要的方式工作。
