PK73912: JMX PORTS DO NOT REBIND AFTER TCP/IP WAS RECYCLED.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When TCP/IP was recycled, the administrative ports did not
  rebind, which causes certain functions not to work.
  

Local fix

• Restart the Servers.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All IBM WebSphere Application Server         *
  *                 V7.0 users on z/OS.                          *
  ****************************************************************
  * PROBLEM DESCRIPTION: The SOAP connector server does not      *
  *                      tolerate TCP/IP recycle on z/OS.        *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The SOAP connector server uses Java ServerSocket to receive
  client requests.  When TCP/IP is stopped, the ServerSocket
  instance is no longer bound.  After TCP/IP is restarted, the
  ServerSocket cannot automatically rebind.  The current code
  repeatedly calls accept() on the ServerSocket instance, which
  may cause the message EDC5122I INPUT/OUTPUT ERROR to be
  displayed.
  

Problem conclusion

• The code has been modified such that once the condition
  represented by "EDC5122I" is detected, a sequence of attempts to
  
  
  
  re-initialize  the SOAP connector's underlying HttpTransport is
  started, which is repeated every 30 secs until TCP/IP restarts.
  This will result in a new ServerSocket being created.  The newly
  
  
  
  created ServerSocket will successfully bind.  The SOAP connector
  
  
  
  server will then accept incoming requests as it did before
  TCP/IP was stopped.
  
  APAR PK73912 is currently targeted for inclusion in Service
  Level (Fix Pack) 7.0.0.3 of WebSphere Application Server V7.0
  for z/OS.
