User response



No errorZero indicates No error returned in the code, and users rarely see this error. You only see it if there is a mistake in the logging.

You can safely ignore this error.



Loop detected in model.

CMDB Impact Simulator returns an error message if the AIS cell finds an unsupported loop in the model.

Remove the loop in your model; loops in your model can cause an unpredictable result. Review the ais.log to find the actual CIs that create the error.



AIS plug-in encountered an authentication error when trying to connect to the AR server.

You typically see this error if the password has been recently changed and the Remedy Action Request System server has not yet been restarted. The old password is still in use.

  1. Review the logon credentials in the pluginsvr_config.xml and ar.cfg files. The logon credentials specified in the pluginsvr_config.xml file override those in the ar.cfg file.
  2. Restart the Remedy AR System server.



Timeout querying the CMDB.

One of the possible causes for this timeout error might be that the BMC CMDB or Remedy AR System server has stopped responding.

  1. Verify that the Remedy AR System server is still running.
  2. Increase the Process Timeout setting for the Remedy AR System server.



Error while trying to retrieve information from the CMDB for CMDB query.Exception returned (for example, with authentication) when performing a query.

Check the ais.log for details about the exception.



An unknown error has occurred in the Atrium Impact Simulator plug-in.Your system encountered a problem with no anticipated cause.

Check the ais.log for details about the error.



Exception while cleaning cache.

The current simulation is invalid.

Note: You should only click Refresh CI when you have actually modified the Configuration Item (CI) impact model.

  1. Close the simulation and try again.
  2. If the problem continues, review both the ais_cell.log or ais.log files for details about the error.
