IT29378: CHANGES TO TCPIPCLIENT CONFIG SERV AFFECT ALL FLOWS WITH TCPIP- CLIENT NODES INSTEAD OF ONLY THOSE USING THE CHANGED CONFIG SERV

APAR status

• Closed as program error.

Error description

• When an mqsichangeproperties command is issued against a
  TCPIPClient type configurable service, all flows using
  TCPIPClient configurable services are locked for update, and all
  such TCPIP connections are closed and restarted. The
  TCPIPDirector should only lock flows that use the named
  configurable service that has changed, and leave the connections
  used by other configurable service names unchanged.
  

Local fix

• n/a
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus v10 who use multiple
  TCPIPClient configurable services in conjuction with TCPIPClient
  nodes.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  An mqsichangeproperties command issued against a TCPIPClient
  configurable service will cause all flows using TCPIPClient
  nodes to drop and re-open their existing connections, including
  flows which are not using configurable services affected by the
  mqsichangeproperties command.
  

Problem conclusion

• This APAR introduces an environment variable
  MQSI_TCPIP_DONT_STOP_ALL_CLIENTS_ON_REFRESH which, if set to any
  non-null value, will only cause the flows affected by the
  configurable service change to drop and re-open their
  connections.
