IT01793: IT IS NOT POSSIBLE TO QUIESCE OR STOP CONNECTION FOR TCP/IP SERVER NODES WITHOUT STOPPING ALL FLOWS USING THESE CONNECTIONS

APAR status

• Closed as program error.

Error description

• TCP/IP connections used by the Server Input Nodes are nominally
  owned by a TCPIP resource manager. Individual flows are either
  notified when new data arrives on a connection, or obtain use of
  the connection when execution of the flow passes through the
  node. Under this model connections are not closed unless all
  flows containing server nodes which use the connections are
  stopped.  It is not therefore possible to prevent new incoming
  connections
  while allowing in flight work to complete.

  USERS AFFECTED:
  All users of IBM Integration Bus version 9 using the TCPIP
  Server nodes.

  There are a number of resource name changes between WebSphere
  Message Broker and IBM Integration Bus Version 9.0. For details

Problem conclusion

• IBM Integration Bus has been enhanced so that TCP/IP connections
  can be quiesced using the command:
  
  mqsichangeproperties IBNODE -e integrationServerName -o
  TCPIP/quiesce/Server -n port,quiesceTimeoutSec -v
  <port>,<waitPeriod>
  
  ---------------------------------------------------------------
  The fix is targeted for delivery in the following PTFs:
  
  Version    Maintenance Level
  v9.0       9.0.0.8
  
  The latest available maintenance can be obtained from:
