can someone tell me if my RFA warm standby parameters are set up correctly? 

\Logger\AppLogger\useInternalLogStrings                      = true
\Logger\AppLogger\fileLoggerEnabled                          = false

\Connections\Connection_RSSL\connectionType                 = "RSSL"
\Connections\Connection_RSSL\traceMsgToFile                 = false
\Connections\Connection_RSSL\rsslPort                       = "Port"
\Connections\Connection_RSSL\serverList                     = "WarmStandbyGroup"
\StandbyLists\WarmStandbyGroup\serverList                   = "IPAddress1,IPAddress2, IPAddress3"

    Yes, the configurations look correct.

    If ADS servers support warm standby, RFA will connect to all servers in the serverList. You can verify the server support from the login refresh in RSSL tracing. The value of SupportStandby must be one.

    <refreshMsg domainType="RSSL_DMT_LOGIN" streamId="1" containerType="RSSL_DT_NO_DATA" ...>
        <key  flags="0x26 (RSSL_MKF_HAS_NAME|RSSL_MKF_HAS_NAME_TYPE|RSSL_MKF_HAS_ATTRIB)"  ...>
            <attrib>
                <elementList flags="0x8 (RSSL_ELF_HAS_STANDARD_DATA)">
              ...
                    <elementEntry name="SupportStandby" dataType="RSSL_DT_UINT" data="1"/>
    ...
                </elementList>
            </attrib>
        </key>
        <dataBody>
        </dataBody>
    </refreshMsg>

    With WarmStandby, one is designated as an active server and
    the rest are standby servers. RFA will internally request the same items from both active and
    standby servers.

    The consumer application receives updates only on the item streams opened on the active server; it does not get
    updates, status, unsolicited refreshes, and generic messages from the standby server(s). If the active server fails, RFA
    notifies one of the standby servers that it is the new active server. That server then begins sending data without the
    consumer application needing to re-request the items.

    For more information, please refer to 16.2 Warm Standby in RFA Developers Guide.
