Error description

  • In case of of hostname misconfiguration on the system it can
    happen that
    the hostname returned by the OS is different from all the ones
    returned
    querying in the network card.
    The agent process while starting, tries to look for the hostname
    to use
    and matches the one returned by the OS with the ones listed in
    the network
    card.
    The configured ipaddress is retrieved using the system function
    gethostname(), that basically returns the same of "uname -n",
    while
    The system functions that are used to detect network info
    are ioctl() and gethostbyaddr().
    If the match is not found, the agent doesn't start.
    

Local fix

  • Fix the network configuration or the system name
    

Problem summary

  •  See apar description.
    Also this can occurs on SolarisSParc
    The ITA agent was not able to confirm the IP information in
    order for
    the agent to be listening.  Found that the real hostname of the
    system
    was included in the /etc/hosts file.  In the line with the real
    hostname there was an alias included before (to the left of) the
    real
    hostname.  This caused the confirmation of IP vs. real hostname
       fail.
    
    Also this can happens on SolarisSPARC if the server address
    with real hostname is not a the TOP of the etc/hosts.
    

Problem conclusion

  •  apar fixed into
    8.6 fp4 9.1 fp2 9.2 fp2 9.3 fp2
    a new environment variable should be set
    "Modify the ita.ini file to have TWS_AGT_HOSTNAME set to a
    valid
    hostname.
    vi <TWAHome>/TWS/ITA/cpa/ita/ita.ini
       Add this line in the section with the heading line:   ITA
    Env
       TWS_AGT_HOSTNAME = secureftp
