RFA serverList parameter

in RFA

I have an application that defines two ADS hosts, A and B, for the “serverList” RFA
parameter. Last week there was a minor issue with host A and I wanted the
application to failover to host B. Restarting the ADS or application was not an
option as it would affect some other people using the ADS or application. I
tried to kill the ADS host A connection for this particular application with "adsmon" to
force the application to failover to host B but this didn’t work as the
application reconnected back to the SAME host, A, right away.


Is there any RFA parameter that in case the ADS connection is killed, the
application will attempt to connect to the NEXT host in the serverList instead
of trying the same host first?

    This is expected behavior of SSL connection type; once RFA disconnects from a server in the serverList, RFA doesn't retry next server, but will retry all servers in the list starting with the first server. So, in this scenario; removing user on adsmon, RFA still reconnect to the same host.

    Currently, there is no configuration parameter for SSL connection for this case. The only way is to migrate application to use RSSL connection.
