Update the message flow thread pool by using the IBM App Connect Enterprise web user interface

You can change the number of threads for a message flow by using the IBM® App Connect Enterprise web user interface to update the size of the thread pool for the message flow.

1. Start the web user interface, by using one of the following methods:
   • From the IBM App Connect Enterprise Toolkit: In the toolkit, right-click the integration node or server and select Start web user interface from the menu.
   • From a web browser: Enter the URL for the web user interface into a web browser, in the following form:

     protocol://hostname:port

     where:

     • protocol is either http or https
     • hostname is the host that you specified in the host property in the .yaml configuration file for the integration node or server (for example, localhost or 127.0.0.1)
     • port identifies the port that is to be used for the web user interface and the toolkit, and must match the value that you set for the port property in the .yaml configuration file. By default the port is set to 4414.
     Examples:

     https://localhost:4414

     or

     https://127.0.0.1:4414

2. In the web user interface, click the Open List of Options icon for the required integration server, and select Open from the drop-down menu.
