    ****************************************************************
    A DB2 for z/OS DDF requester will always need to request
    name resolution services from TCP/IP if the IPADDR column in
    an SYSIBM.IPNAMES row is a domain name, as opposed to an
    IPv4 or IPv6 address.
    A DB2 for z/OS DDF server will always need to request name
    resolution services from TCP/IP if a domain name is provided
    in the context definition of a trusted inbound client
    connection.
    The name resolution service involves two calls to TCP/IP.  The
    first call causes TCP/IP to acquire storage in the DB2 ssnmDIST
    address space that contains the required information.  Once
    the information is processed by DB2, the second call causes
    TCP/IP to free the storage that it acquired.
    DB2 corrupted the storage address provided to TCP/IP during
    the second call.  As a result, the storage is not freed which
    causes a storage leak leading to various Short On Storage
    related symptoms.
    

Problem conclusion

  • DB2 has been changed to ensure the storage address it obtains
    via any TCP/IP name resolution service request is subsequently
    passed back to TCP/IP during the free name resolution service
    resources requests.
