告警日志介绍   告警日志文件是一类特殊的跟踪文件（trace file）。告警日志文件命名一般为alert_<SID>.log，其中SID为ORACLE数据库实例名称。数据库告警日志是按时间顺序记录message和错误信息。   告警日志位置 在ORACLE 10g中，BACKGROUND_DUMP_DEST参数确定了告警日志的位置，但是告警日志的文件名无法修改，告警日志的名称为：alert_<SID>.log ,其中<SID>是实例的名称。BACKGROUND_DUMP_DEST参数是动态的。 SQL> show parameter background_dump_dest; NAME TYPE VALUE--------------------- ----------- ------------------------------background_dump_dest string /u01/app/oracle/admin/GSP/bdumpSQL> 告警日志以及所有后台跟踪文件都会被写至BACKGROUND_DUMP_DEST参数所指定的目录。 在ORACLE 11g 以及ORACLE 12c中，告警日志文件的位置有了变化。主要是因为引入了ADR(Automatic Diagnostic Repository:一个存放数据库诊断日志、跟踪文件的目录)，关于ADR对应的目录位置可以通过查看v$diag_info系统视图。如下所示（ORACLE 12c ） SQL> select * from v$diag_info; INST_...
