In order to troubleshoot SOLIDWORKS PDM connectivity issue between the Archive Server and client, a simple ping test can be used. The ping test is performed on the client computer.
From inside Windows “Start”, select run and type in CMD.
In the command dialogue box enter ping followed by the archive server (ping <server name>). This simple test will determine if the client computer can see the archive server.
Being able to ping the server may not be sufficient to discover problems though. Slow connections lead to poor performance and not being able to access data. To test for slow connections we can increase the pack size, using the following syntax ping <server name> -t -l 1500
the -t option will ping the <server name> continuously until stopped by the user. Pressing Ctrl-C on your keyboard to stop the ping test. The -l option defines the packet size to be used in the test. A normal ping packet is only 8 bytes which is not a good test of actual TCP packets. A typical TCP packet is usually around 1500. This number can be increased up to 64000 but this will likely cause fragmentation of the packets.
Any dropped packets or excessive latency times indicate a problem with the connection to the server. There are many variables that can determine the impact of slow connections, but the below values can be user as a general guide.
- <40 ms is normal in a local network environment
- <80 ms is workable for an internet connection, but problems can occur when accessing larger amounts of data. This value is high for a local network environment
- >80 ms performance issues will be noticeable and failures will occur
- >120 ms performance degradation will be quite noticeable and the number of failures will increase significantly
- >200 ms connection issues are critical and access to data may not be possible.
Being able to connect to the server is only one aspect that needs to be looked at, communication issues may also need to be addressed. My colleague’s article “How to Perform a Telnet Test“
