WSO2 BAM wirh offset 1. Cassandra 错误

Question

我在启动 BAM 服务器时遇到问题。 我的机器有 IP 1.33.33.127 和主机名“srv-lc-presen”。

我已经使用此文档进行了配置： Monitoring and statistics.

我已经修改了 at carbon.xml。我将它设置为 1。

我已经修改了 master-datasources.xml 并设置了 WSO2BAM_CASSANDRA_DATASOURCE url = jdbc:cassandra://srv-lc-presen:9161/EVENT_KS WSO2BAM_UTIL_DATASOURCE url = jdbc:cassandra://srv-lc-presen:9161/BAM_UTIL_KS

我已尝试使用 localhost、1.33.33.127 和 srv-lc-presen。 我总是遇到同样的错误：

新信息

我尝试重新配置，但没有发现问题。 我在 BAM 控制台中看到此错误

在 API Manager 控制台中

如果您不使用通知功能，请在启动时使用此命令或编辑 wso2server.sh sh wso2server.sh -Ddisable.notification.task
