Application logging

Last Updated : Jun 05, 2026 |

If you run Orchestration Designer applications on Experience Portal, ensure that the applications use Dialog Designer version 5.1 SP3 or later. Application logging fails when you use Dialog Designer runtime versions earlier than 5.1 SP3 with Experience Portal.

If you run a Dialog Designer or Orchestration Designer application that does application logging, and the Experience Portal system is configured to handle more than 75 simultaneous calls, you must make the following configuration change on the Primary EPM:

  1. Log in to Linux on the Primary EPM server as a user with root privileges.

  2. Open the file $CATALINA_HOME/conf/server.xml in a text editor.

  3. Find the entry maxThreads="500" in <Connector port="3009".

  4. Change the value from 500 to 1000.

  5. Save and close the file.

  6. Run the /sbin/service vpms restart command to restart the vpms service.
