Handling system error messages

A system error might indicate a system problem, a resource problem, or an unexpected condition.

These problems might be within QMF, the database manager, or some other software component. System errors are indicated by the following message:
Sorry, a system error occurred. Your command may not have been executed.
Press the Help key to display more information about the message.

All uncommitted changes to the database are rolled back when a system problem stops QMF. Error information about the system problem is written to the trace data, which is the only source of information for a system problem that stops QMF. The Q.ERROR_LOG table contains information about a system error only if the error occurred while the database was still running.
