Goal

In case of the following Domain configuration on Soalris 9, failover mechanism does not work.

*DM_TDOMAIN
TDOM1   NWADDR="//TuxMachineName:port1" # local domain
TDOM2   NWADDR="//TuxMachineName:port2" # primary remote domain
        CONNECTION_POLICY=ON_STARTUP
        LACCESSPOINT=TDOM1
        FAILOVERSEQ=110
TDOM2   NWADDR="//TuxMachineName:port3" # secondary remote domain
        CONNECTION_POLICY=ON_STARTUP
        LACCESSPOINT=TDOM1
        FAILOVERSEQ=120

When GWTDOMAIN of TuxMachineName:port2 is down, TDOM1 should connect TuxMachineName:port3 after trying TuxMachineName:port2,  however it does not work
and following log outputs in ULOG.
132658.TuxMachineName!GWTDOMAIN.xxx.4.0: LIBGWT_CAT:1303: ERROR: Network error occurred during connection establishment
132658.TuxMachineName!GWTDOMAIN.xxx.4.0: LIBGWT_CAT:1512: ERROR: Unable to connect to remote domain TDOM2
132658.TuxMachineName!GWTDOMAIN.xxx.4.0: LIBGWT_CAT:1500: INFO: Retrying domain (domainid=<TDOM2>) every 60 seconds

If primary domain is remote machine it will be success failover(this problem occurs on same machine domain configuration)

132855.TuxMachineName!GWTDOMAIN.xxx.4.0: LIBGWT_CAT:1129: INFO: Connection established with domain (domainid=<TDOM2>)

In the case of HP-UX, it will be success failover with Network error code=245 132543.TuxMachineName!GWTDOMAIN.xx.5.0: LIBGWT_CAT:1249: WARN: Connection to TDOM2 address //TuxMachineName:port2 failed, Network error(245) 132543.TuxMachineName!GWTDOMAIN.xx.5.0: LIBGWT_CAT:1305: INFO: A connection attempt has failed for TDOM2, trying new address //TuxMachineName:port3 132543.TuxMachineName!GWTDOMAIN.xx.4.0: LIBGWT_CAT:1129: INFO: Connection established with domain (domainid=<TDOM2>)
