Oracle日志文件管理与查看 from:http://hi.baidu.com/shuker/item/25ee611ee960c7426826bb1f 1.查询系统使用的是哪一组日志文件: select * from v$log; 2.查询正在使用的组所对应的日志文件: select * from v$logfile; 3.强制日志切换: alter system switch logfile; 4.查询历史日志: select * from v$log_history; 5.查询日志的归档
1.Oracle log 每次切换会记录到告警日志中 设想写个方案来查看log切换频率来判断Oracle log是否应该更改大小. 2.sql a.查看redo日志信息 select * from v$log b.查看日志切换频率 )*,) and b.THREAD#= order by a.SEQUENCE# desc; 或者 )*,) diff ) order by sequence# desc;
一.第一种方法 1.切换到oracle用户 su - oracle 2.进入sqlplus窗口 sqlplus / as sysdba 3.执行sql命令,查看trace文件位置:background_dump_dest就是后台日志 show parameter dump; 4.切换到trace目录下 cd /u01/app/oracle/diag/rdbms/prod/PROD/trace 5.查看带有alert关键字的文件,alert_INSTANCENAME.ora即是alert日志的名字
