How to use onmode -Z

The onmode -Z address command is intended for use only if communication between the coordinator and the participant is broken. To ensure that communication is really broken, the onmode -Z command does not run unless the thread that was executing the piece of work has been dead for the amount of time specified by TXTIMEOUT. For more information about this option, see the IBM® Informix® Administrator's Reference.

The address parameter is obtained from onstat -x output. For more information about the onstat -x option, see the IBM Informix Administrator's Reference.
