Web Agent R12.52 SP1 CR06 is connecting to two Policy Servers in Round Robin mode. All are on RHEL.
If one of two Policy Servers gets down, it was supposed that Web Agent reconnected to alive Policy Server after the value of RequestTimeout in HCO (default 60 sec) passed.
However, it was observed that it only took about seven seconds for the reconnection.
What is the specification of Round Robin mode in such situation ?
Web Agent 12.52 SP1 CR06 / RHEL Policy Server 12.7 / RHEL
This obseravation is the expected behavior since Web Agent r12.51 CR04.
Here is a summary of Connection between Web Agent and Policy Servers. 1. Web Agent polls Policy Server periodically. 2. The connection is created using non-blocking sockets. Web Agent waits up to RequestTimeout before deciding Policy Server is unavailable.
Notes: Regarding RequestTimeout, the functionality has been changed as per 12.51 CR04 fix 53774 (DE103076). In CreateConnection function, code is modified to use non-blocking sockets.
As a result, RequestTimeout explanation is as following: "The RequestTimeout parameter specifies the number of seconds. The trusted host waits up to the value before deciding that a Policy Server is unavailable."
