Executing Rational Performance Test script for SAP results in "Runtime error - MESSAGE_TYPE_X"

Technote (troubleshooting)


Attempts to execute a SAP recorded test script from IBM Rational Performance Tester (RPT) results in the error "Error : Runtime error - MESSAGE_TYPE_X " displayed from Execution Event Console window.


The Rational Performance Tester agent was started as a service instead as a process.

By default the agent is started as a service with name "Majordomo" when a RPT agent is installed and runs on OS start up.

Resolving the problem

The Majordomo service should be stopped and the RPT agent should be started as a process as follows:

  1. Stop the agent service by using Windows task manager.
    Find a service named "Majordomo" in services tab of task manager and stop it.

  2. Browse to the agent installation directory.
    For example: C:\Program Files\IBM\SDP\Majordomo

  3. Start the agent as a process
    • Launch the "Majordomo.bat"
    • Execute from the command line

  4. Check that the Majordomo process is started successfully.

This agent running as a process is now ready for load generation from a RPT schedule.
