APAR status

  • Closed as program error.

Error description

  • Customer is using SNA/LLC2 printer session with PCOM 6.0 on
Windows 7 operating system.

Customer's VSE CICS host application is restarted every day at
midnight. In the morning, customer cannot get print jobs.
The workaround is to restart SNA node each morning.

Local fix

  • Stop and restart the SNA node each morning.

Problem summary

  • ****************************************************************
* USERS AFFECTED: All users of SNA LLC2 3270 host printer      *
*                 sessions                                     *
****************************************************************
* PROBLEM DESCRIPTION: When z/VSE CICS host application is     *
*                      restarted the user cannot get print     *
*                      jobs to the PCOM printer session.       *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
If a SNA printer is connected over an LLC2 link and it is
reset by the receipt of DACTLU/ACTLU then if the printer is
reconnected to the server before the ACTLU is received, VTAM
may fail to restart the SNA session (no BIND is issued).

Problem conclusion

  • The problem is caused by the ACTLU RSP issued by PCOMM
incorrectly indicating that the LU-LU session is already
active. APPN.SYS has been changed to correct this parameter.
This problem was introduced through previous APAR JR44768.

Fix scheduled for PCOM 6.0.11 Refresh Pack
