TRACE_ENABLED controls tracing of the execution history, or code path, of Oracle. Oracle Support Services uses this information for debugging.
TRACE_ENABLED is set to
true, Oracle records information in specific files when errors occur.
Oracle records this information for all instances, even if only one instance terminates. This allows Oracle to retain diagnostics for an entire cluster.
Although the overhead incurred from this processing is not excessive, you can improve performance by setting
false. You might do this, for example, to meet high-end benchmark requirements. However, if you leave this parameter set to
false, you may lose valuable diagnostic information. Therefore, always set
true to trace system problems and to reduce diagnostic efforts in the event of unexplained instance failures.
