IC89442: PCOM: 3270 SESSION HANG AT TSO LOGOFF AFTER 6.0.5 REFRESH

Personal Communications 6.0.7

APAR status

• Closed as program error.

Error description

• After installing the 6.0.5 Refresh of PCOM version 6 on Windows
  7 32bit SP1, the 3270 emulator session will hang after logging
  off the TSO host.
  
  Closing the session window results in PCSWS process staying
  active. To start a new session, PCSWS and PCSCM need to be
  stopped from Task Manager.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of PCOM Keep Alive                 *
  ****************************************************************
  * PROBLEM DESCRIPTION: 3270 display session hang when logoff   *
  *                      from TSO with automatic disconnect set  *
  *                      in host side and Keep Alive enabled in  *
  *                      the PCOM session profile.               *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When PCOM Keep Alive is set in the 3270 session profile:
  
  [KeepAlive]
  EnableTelnetKeepAlive=Y
  
  and the user logs off a TSO host that has Automatic Disconnect
  set in the host LU, the session will hang. This is caused by
  the CreateThread() for Send_KeepAlive() never completing due
  to the timing of the function call.
  

Problem conclusion

• PCSTLNET.DLL has been changed to add a delay after the
  CreateThread() for Send_KeepAlive() in the send monitoring
  thread function to ensure that Send_KeepAlive() was created
  successfully.
  
  Fix is scheduled for PCOM 6.0.7 Refresh Pack
