TRACE_ENABLED
TRACE_ENABLED controls tracing of the execution history, or code path, of Oracle. Oracle Support Services uses this information for debugging.
When TRACE_ENABLED is set to true , Oracle records information in specific files when errors occur. See Oracle9i Real Application Clusters Deployment and Performance for the types of files and the default destination directories in which Oracle records the execution history.
Oracle records this information for all instances, even if only one instance terminates. This allows Oracle to retain diagnostics for the entire cluster.
Although the overhead incurred from this processing is not excessive, you can improve performance by setting TRACE_ENABLED to 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 TRACE_ENABLED to true to trace system problems and to reduce diagnostic efforts in the event of unexplained instance failures.
本文介绍了Oracle数据库中的TRACE_ENABLED参数,该参数控制Oracle执行历史的跟踪记录。当设置为true时,Oracle会在错误发生时记录相关信息到特定文件中,这对于调试非常有用。尽管启用此功能会带来一定的性能开销,但在遇到实例故障时可以提供宝贵的诊断信息。
