SnapCenter 插件与 SnapCenter 服务器之间的连接断开 路由路径

适用场景

• SnapCenter 服务器
• 适用于SQL的SnapCenter插件(SCSQL)
• 适用于Exchange的SnapCenter插件(SCE)
• 适用于Oracle的SnapCenter插件(SCO)

问题描述

连接会随机中断一段时间、从而导致无法更新回SnapCenter服务器、例如从SMCore日志进行更新：

DEBUG SMCore_<JOB> PID=[<Process>] TID=[<Thread>] RemoteUrl: https://<SNAPCENTER_FQDN>:8146/BackupService.svc/DeleteBackup
ERROR SMCore_<JOB> PID=[<Process>] TID=[<Thread>] WebException Encountered, Response null
ERROR SMCore_<JOB> PID=[<Process>] TID=[<Thread>] Exception in method: Invoke.
System.Net.WebException: The underlying connection was closed: A connection that was expected to be kept alive was
closed by the server. ---> System.IO.IOException: Unable to read data from the transport connection:
An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException:
An existing connection was forcibly closed by the remote host
   at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)

(在本例中为备份删除)请求已发送、但连接在两分钟后断开。
从“RemoteURL”行上的时间戳到带有“”的下一行都可以看到这种情况Exception in method。

可以看到的另一个错误、例如、在仍在"运行"的验证作业的详细信息视图中、可能是：

The underlying connection was closed: An unexpected error occurred on a receive.
