Hi All,

While observing my Production System I can see some errors in the trace files of the Work Processes.

Below is some lines of the error.

Hi ,

Please read the note . there may be more than reasion for this problem in your senrio. I am pating here a some part of the note .

During start of one or several R/3 instances, many work processes try to connect to the database concurrently over the Listener. For every work process, the Listener must create a shadow process and coordinate the connection setup between the work process and the shadow process. If other connection requests reach the Listener while it is still busy setting up the connections for the previous requests, the requests are put into a queue. If the size of the queue ist not dimensioned adequately for accepting all incoming requests for work processes, additional connection requests are denied with errors

The solution of this proble is increass the queue size in listner.ora file under /oracle/<SID>/102_64/network/admin/listner.ora.

1. If the problem occurs with TCP connections, it can frequently be corrected by enlarging the Listener queue using the parameter QUEUESIZE. If this parameter is not defined in listener.ora, the operating system default value is used. For some platforms (e.g. NT/Windows 2000), this is set to the small number of 5

.

Please supplement the queue length in the file listener.ora using the parameter QUEUESIZE. To set the length e.g. to 30, add the following parameter at the end of the ADDRESS list for the TCP protocol:
  LISTENER =
    (ADDRESS_LIST =
      ...
      (ADDRESS =
          (COMMUNITY = SAP.WORLD)
          (PROTOCOL = TCP)
          (HOST = <hostname>)
          (PORT = <port>)
          (QUEUESIZE = 30)
      )
    ) 

              After that, restart the Listener.
