  • 1.  IIB vs ACE HTTPSConnector properties

    Posted Mon May 02, 2022 09:39 AM
    In IIB v10 we used property below , with ACE v11 there is no such parameter.
    -n maxThreads
    Set the value to the maximum number of threads that can be created by the HTTPConnector.
    • Value type - integer
    • Initial value - 200

    After reviewing ACE v11 this property maxThreads does not exist. However, the following 2 properties seem to be similar to it. Which one corresponds to maxThreads. I am kind of confused as to which one it is.

    -n ListenerThreads
    This property specifies the number of threads that are available for the listener to run on. If this property is set to -1 or 0, the number of available threads is half the number of available CPU cores on the system.
    • Value type - integer
    • Initial value - -1
    -n MaxConnections
    Set the value to the maximum number of inbound HTTP connections that the listener can accept. The default is -1 (infinite).
    • Value type - integer
    • Initial value - -1

    In IIB, maxThreads corresponds to a listener thread and a connection.  ACE has this divided into two properties as you do not need to have a thread for each connection.  Thus, to answer your question, you most likely need to change MaxConnections.  You should increase ListenerThreads if you receive a large number of connections in a burst, many at one instance as this could overload a small number of listener threads.
