理解数据库中的 DISABLE_ARCHIVE_LOGGING 在数据库管理中,数据的可恢复性和性能是设计时需考虑的重要因素。Oracle 等数据库系统具有归档日志(Archive Logging)选项,允许用户在操作数据库时记录所有的更改。然而,在某些情况下,用户可能会选择禁用归档日志,这就是 “DISABLE_ARCHIVE_LOGGING” 的角色。 什么是归档日志?
1.1 关闭redo日志的生成(TRANSFORM=DISABLE_ARCHIVE_LOGGING:Y) Data Pump中引入了新的TRANSFORM选项,这对于对象在导入期间提供了关闭重做生成的灵活性。当为TRANSFORM选项指定了DISABLE_ARCHIVE_LOGGING值,那么在整个导入期间,重做生成就会处于关闭状态。这一功能在导入大型表时缓解了压力,并且减少了过度的redo产生,从而加快...

I have a standalone JMS application (org.omg.CORBA.ORBInitialHost, org.omg.CORBA.ORBInitialPort etc. stuff), all is OK, but the RA is logging tons of text to my console. How could I disable it? (or redirect to file would be even better!) ...

log4cxx.properties file. How can I completely disable logging using this file? That depends on your LIB and how it configures log4cxx. By default logging can easily be deactivated by settings the log level for all loggers to NONE.http://logging.apache.org/log4cxx/usage.htmlMit freundlichen...
You can enable or disable logging for all performance counters. If you enable logging, all performance counters are logged even if they are not displayed. If you disable logging, no counters are logged and only those still in the log can be displayed. ...
