Failover of Directory Servers
If you are using an LDAP-compliant security realm, the Windchill RV&S Agent supports the use of multiple directory servers to handle authentication when one server fails. The Windchill RV&S Agent uses the Domain Name Service (DNS) list to find all directory servers associated with the server host name and authenticates to the first server in the list that responds to the connection request. To minimize waiting time, the Windchill RV&S Agent maintains a pool of the directory servers that it has connected to.
If you are using failover, you should review the following cache settings in
