与 Azure 服务总线的连接工作 5 分钟,然后 5 分钟不工作
我正在尝试连接到基于云的 (Azure) 服务总线。它是从 SAP/ABAP 系统直接到端口 443 上的服务总线。
问题是通信有时工作良好,有时又不太好。 经过一番分析后,我们设置了一个监控批处理作业,每分钟发送一个请求:看起来通信在大约 5 个请求(分钟)内工作正常,然后在另外 5 个请求(分钟)内停止工作。然后它可以正常工作 5 分钟,依此类推。
在通信工作期间,我们能够向服务总线发送 HTTPS 请求,而在通信中断时,我们在 SAP 中收到 HTTP 404 和 SM59 事务,显示:直接连接到 xxx 失败:NIECONN_REFUSED(-10)。
奇怪的是,如果我们登录到源计算机并远程登录到服务总线,连接会立即再次开始工作 5 分钟。我们刷新/重置 SAP 中的 DNS 缓存也会发生同样的情况。然而,服务总线永远不会更改 IP,因此不清楚为什么这会使连接继续工作 5 分钟。
Azure 中的其他组件工作完全正常,我们仅在服务总线上遇到此问题。有谁知道 5 分钟后 Service Bus 是否有变化或者经历过类似的事情?
I'm trying to connect to a cloud based (Azure) Service Bus. It is from a SAP/ABAP system directly to Service Bus on port 443.
The problem is that the communication works good sometimes, and not so good sometimes.
After some analysis we set up a monitoring batch job sending one request every minute: It seems that the communciation works fine for about 5 requests (minutes) and then to be down for another 5 requests (minutes). Then it works fine for 5 new minutes and so on.
During the time the communication is working we are able to send HTTPS requests to Service bus, while the communication is down we get a HTTP 404 and SM59 transaction in SAP shows: Direct connect to xxx failed: NIECONN_REFUSED(-10).
The strange thing is that if we login to the source machine and do a telnet to the service bus, the connection starts to work again immediately for another 5 minutes. Same thing happens of we flush/reset the DNS cache in SAP. However, the servicebus never changes IP so it unclear why that makes the connection to work for 5 new minutes.
Other components in Azure works totally fine, we're only experiencing this issue with Service Bus. Does anyone know if there is something changing in Service Bus after 5 minutes or have experienced something similar?
