commons-logging 是apache最早提供的日志的门面接口。它的主要作用是提供一个日志门面，使用者可以使用不同的日志实现。...用户可以自由选择第三方的日志组件作为具体实现，像log4j，或者jdk自带的logging， common-logging会通过动态查找的机制，在程序运行时自动找出真正使用的日志库。...官网：https://commons.apache.org/proper/commons-logging/ slf4j 全称：Simple Logging Facade for Java 官网：https...总结 1、commons-loggin,slf4j只是一种日志抽象门面，不是具体的日志框架。 2、log4j,logback是具体的日志框架。...3、一般首选使用slf4j+logback，或者slf4j+log4j,commons-logging+log4j。

NOLOGGING：正好与LOGGING、FORCE LOGGING 相反，尽可能的记录最少日志信息到联机日志文件。...注：FORCE LOGGING并不比一般的LOGGING记录的日志多,数据库在FORCE LOGGING 状态下,NOLOGGING选项将无效,因为NOLOGGING将破坏DATAGUARD的可恢复性...归档模式中的LOGGING或FORCE LOGGING 支持介质恢复，而NOLOGGING 模式不支持介质恢复。...一般建议将整个数据库设置为FORCE LOGGING或基于表空间级别设定FORCE LOGGING，而不建议两者都设置为FORCE LOGGING。...- SYSTEM LOGGING NO UNDOTBS1 LOGGING NO SYSAUX LOGGING NO TEMP NOLOGGING NO USERS LOGGING NO 查看对象级别的日志记录模式
