Two problems with the GSS's

[stonnet72]

Here are two problems I am currently experiencing:

- IP failover with no apparent outage at primary site

- Unreliable GSS proximity

Has anyone experienced any of these issues with a GSS?

Please advise what you did to resolve the issue. Thank you so much.

network proximity uses either a TCP SYN-ACK or an ICMP Echo to determine round-trip times. This is often a problem because most firewalls are stateful and will drop a TCP SYN/ACK as an out-fo-state packet. Often times, ICMP Echo requests are also dropped. The other problem is that any congestion within the network can lead to unpredictable RTTs.

You can use the following commands to see the actual RTTs recorded in the PDB.
