Local fix

Problem summary

  • JVM is designed to fetch the DNS information from
    /etc/resolv.conf file on all UNIXes including z
    /OS. However, on z/OS, it is not mandatory to have
    /etc/resolv.conf file.  Hence the DNS information would be
    populated with null in such scenarios on z/OS
    

Problem conclusion

  • This defect will be fixed in:
    5.0.0 SR11 FP2
    .
    JVM on z/OS has updated to invoke API res_init(),which
    internally follows the search order on
    z/OS to fetch the required DNS information.
    .
    To obtain the fix:
    Install build 20100409 or later
    

Temporary fix
