Error description

  • NET_IF, NET_IF_IPV6 does not work well in case of hostname with
    more IPs addresses.
    
    
    The agent binf the TCP port on the fisrt intefrace of the list
    of the hostname IPs, if the hostname has more than one addresses
    it uses the first but does not respect the protocol, i mean if
    you set in NET_IF= host1.company.com and this host has two
    adrresses ( solved by the resolver - DNS / etc )
    
    ::1
    <some_ipv4_adress>
    
    the agent bind on the first address ::1 ( IPv6 ) instead the
    first Ipv4.
    

Local fix

  • Change the host resolution or bind for 0.0.0.0 and ::
    

Problem summary

  • The problem is that when the sock_addr data structure is created
    in agent process the address family is not specified and the
    system decides to return ipv4 or ipv6 addresses (since many
    addresses are defined). The fix is to explicitly specify the
    address family according to configuration.
    

Problem conclusion

  • This apar will be fixed   8.6.0-TIV-TWS-FP0003
