PI80970: ISSUES WITH SPECIFICATION OF A LOCAL PORT AT IMS V15

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• 1.  At IMS V15 use of TCPIP PORTID=LOCAL is no longer supported
  by IMS Connect but specification of a LOCAL port is still
  tolerated. However, specification of a LOCAL port at IMS V15
  will cause IMS Connect Extensions Publisher API initialization
  to enter a CPU-intensive loop and the subsequent IMS Connect
  server shut down will hang. The Publisher API has been modified
  to circumvent this issue.
  2.  Added defensive code to handle unexpected Journal event
  content.
  

Local fix

• Remove the LOCAL PORTID from their ICON configuration and
  restart ICON.

  1. At IMS V15 use of TCPIP PORTID=LOCAL is no longer supported
     by IMS Connect but specification of a LOCAL port is still
     tolerated. However, specification of a LOCAL port at
     IMS V15 will cause IMS Connect Extensions Publisher API
     initialization to enter a CPU-intensive loop and the
     subsequent IMS Connect server shut down will hang.
  
  2. At IMS V14 and earlier, use of TCPIP PORTID=LOCAL can result
     in an abend S0C4 in module CEXCONSS.
  

Problem conclusion

• 1. The Publisher API has been modified to circumvent the issues
     related to the specification of a LOCAL port at IMS V15
     or above.
  
  2. Corrected logic error in CEXCONSS to prevent the possibility
     of the loop which resulted in an abend S0C4.
