ADR(Automatic Diagnostic Repository)是Oracle 11g的一个存放数据库诊断日志、跟踪文件的目录,也作为ADR base。在实例中通过设置初始化参数DIAGNOSTIC_DEST来改变,这个参数是动态参数,修改这个参数后对应的目录和日志文件会立刻被生成并使用,默认在ORACLE_BASE下。
Oracle 11g同时提供了一个ADRCI(ADR Command-Line Utility)命令行工具来查看ADR中的alert日志和trace信息,并生成健康报告,ADRCI工具在$ORACLE_HOME/bin下面,安装oracle 11g以后默认就有·
1、登录adrci
[oracle@Web_121_127 ~]$ adrci
ADRCI: Release 11.2.0.4.0 - Production on Mon Nov 27 10:38:30 2017
Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved.
ADR base = "/oracle/app/oracle"
2、设置ADR HOME
查看ADR HOME
adrci> show home
ADR Homes:
diag/rdbms/powerdes/powerdes
diag/tnslsnr/Web_121_127/listener
diag/diagtool/user_oracle/host_363427775_80
设置并指定单一ADR HOME:
adrci> set homepath diag/tnslsnr/Web_121_127/listener
adrci> show home
ADR Homes:
diag/tnslsnr/Web_121_127/listener
3、show alert
show alert用于格式化log.xml中的全部信息。输入普通alert_.log格式。保存到临时的文本文件中用编辑器打开。使用set editor vi 来指定编辑器(退出show alert显示就是关闭该编辑器。
用-tail获得最后20条的数据,或者指定一个大小
show alert -tail 20
实时跟踪日志
show alert -tail -f
-p选项可以筛选条件,如
show alert -tail -f -p "MESSAGE_TEXT like '%ORA-%'"
4、配置控制起点
adrci> show control
ADR Home = /oracle/app/oracle/diag/rdbms/powerdes/powerdes:
*************************************************************************
ADRID SHORTP_POLICY LONGP_POLICY LAST_MOD_TIME LAST_AUTOPRG_TIME LAST_MANUPRG_TIME ADRDIR_VERSION ADRSCHM_VERSION ADRSCHMV_SUMMARY ADRALERT_VERSION CREATE_TIME
-------------------- -------------------- -------------------- ---------------------------------------- ---------------------------------------- ---------------------------------------- -------------------- -------------------- -------------------- -------------------- ----------------------------------------

1 rows fetched
SHORTP_POLICY trace file 保留时间, LONGP_POLICY incident信息保留时间,单位是小时。这两个参数可以使用下面两个命令修改:
set control (LONGP_POLICY = 2160)
set control (SHORTP_POLICY = 360)
5、清理数据
adrci> show problem
ADR Home = /oracle/app/oracle/diag/rdbms/powerdes/powerdes:
*************************************************************************
PROBLEM_ID PROBLEM_KEY LAST_INCIDENT LASTINC_TIME
-------------------- ----------------------------------------------------------- -------------------- ----------------------------------------
3 ORA 7445 [kkorminl()+348] 216364 2017-11-20 22:00:18.227000 +08:00
2 ORA 7445 [kkorminl()+317] 216359 2017-11-26 13:37:37.993000 +08:00
1 ORA 7445 [kkorminl()+306] 240004 2017-11-27 01:38:13.972000 +08:00
3 rows fetched
delete from problem where problem_id=3
删除incident同理:
delete from incident where INCIDENT_ID=216364;
删除alter日志等文件推荐使用purge
adrci> help purge
Usage: PURGE [[-i <id1> | <id1> <id2>] |
[-age <mins> [-type ALERT|INCIDENT|TRACE|CDUMP|HM|UTSCDMP]]]:
Purpose: Purge the diagnostic data in the current ADR home. If no
option is specified, the default purging policy will be used.
Options:
[-i id1 | id1 id2]: Users can input a single incident ID, or a
range of incidents to purge.
[-age <mins>]: Users can specify the purging policy either to all
the diagnostic data or the specified type. The data older than <mins>
ago will be purged
[-type ALERT|INCIDENT|TRACE|CDUMP|HM|UTSCDMP]: Users can specify what type of
data to be purged.
Examples:
purge
purge -i 123 456
purge -age 60 -type incident
ADRCI Purge命令的操作单元是文件而不是文件内容,只有整个文件的最后更新时间在我们指定的purge命令条件之前,该文件才会被删除,也就是说,要不整个 文件都删除,要不一点儿也不删除。
删除一天前的alert log
adrci> show homes
ADR Homes:
diag/rdbms/powerdes/powerdes
diag/tnslsnr/Web_121_127/listener
adrci> set homepath diag/rdbms/powerdes/powerdes
adrci> purge -age 1440 -type ALERT
adrci> show alert
purge -age 20 # 删除20分钟前的所有信息
purge -age 1440 -type ALERT # 删除一天前的alert log
purge -age 1440 -type TRACE # 删除一天前的trace 文件
