Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of QCF, that use the QCF panels to     *
  *                 search for a message whithin large number of *
  *                 messages. IMS is looking for the message to  *
  *                 send response back to the server. If a       *
  *                 single message that satisfies the search     *
  *                 criteria is not found within 30 seconds, the *
  *                 server/IMS  connection is timed out and      *
  *                 message IQC7003E shows.                      *
  ****************************************************************
  * PROBLEM DESCRIPTION: By default server/IMS connection is     *
  *                      timed out after 30 seconds. If the      *
  *                      queues are large and a single message   *
  *                      can not be found within 30 seconds, or  *
  *                      the end of the queues is not reached    *
  *                      within 30 seconds- the connection is    *
  *                      timed out. WAITTIME parameter is used   *
  *                      to set the default 30 seconds to new    *
  *                      value. WAITTIME is used now to time out *
  *                      the TSO client/server connection and    *
  *                      the also the sever/IMS connection.      *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Time out interval for server/IMS connection can be modified
  using the WAITTIME parameter. WAITTIME is the time TSO clients
  waits on server and IMS to finish the function, WAITTIME is
  also the time server waits on a single response from IMS -
  message that satisfies the criteria or end of messages.
  

Problem conclusion

• Install the PTF and recycle server and TSO client.
