The Administration Engine Tools Log records messages about Control Center functions. Logging is always turned on while the Control Center is running. Information in this ASCII file (located in the sqlbin subdirectory of sqllib) is meaningful only when there is an error condition. The log file and the trace file are used together to determine the cause of the error condition. The log file must periodically be pruned by the database owner or administrator (using any ASCII editor), because records are always appended to it.
