java通过mysql 驱动(8.0.21 和 5.1.47都试过)连接ob(通过ob_proxy, ob版本是5.7.25-OceanBase_CE-v4.2.0.0)时好时坏,报以下错误:
Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
附件中上传了压缩的ob日志
obproxy.log.zip (3.8 MB)
observer.log.zip (3.0 MB)
查看另一台服务器上,发现这个错误,不知道会不会是这个原因:
query and update last id fail(ret=-4076, ret=“OB_NEED_WAIT”)
还请ob的开发人员帮助看下!
