Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of IBM Tools Base for z/OS         *
  *                 Version 1 Release 7 (FMID: HAHN170) who use  *
  *                 Distributed Access Infrastructure.           *
  ****************************************************************
  * PROBLEM DESCRIPTION: When the DAI server detects a logon     *
  *                      error, it returns an error message to   *
  *                      the DAI client and requests that the    *
  *                      socket be forcefully closed. This may   *
  *                      cause the TCP connection to be          *
  *                      disconnected before the DAI client      *
  *                      receives an error response.             *
  ****************************************************************
  * RECOMMENDATION: Apply the PTF for this APAR.                 *
  ****************************************************************
  When the DAI server detects a logon error, it returns an error
  message to the DAI client and requests that the socket be closed
  with the LINGER option set to a value of 0. This setting causes
  the socket to be closed immediately even if there is unsent data
  on the socket, which could cause the TCP connection to be
  disconnected before the DAI client receives the error response.
  

Problem conclusion

• The following modules have been modified so that TCP connections
  are normally disconnected:
