oracle清除日志
作者:互联网
近日发现oracle占用的空间很大,经查,发现是
/u01/app/oracle/diag/rdbms/orcl/orcl/alert 警告日志
/u01/app/oracle/diag/rdbms/orcl/orcl/trace 跟踪日志
这两个目录日志文件太多。占用十几个G
用adrci清除日志
先确定目录
SQL> select value from v$diag_info where name ='Diag Alert'; VALUE -------------------------------------------------------------------------------- /u01/app/oracle/diag/rdbms/orcl/orcl/alert SQL> select value from v$diag_info where name ='Diag Trace'; VALUE -------------------------------------------------------------------------------- /u01/app/oracle/diag/rdbms/orcl/orcl/trace
adrci是操作系统下的oracle命令,可以直接运行adrci
[oracle@dom169 /]$ adrci ADRCI: Release 12.1.0.2.0 - Production on Sat Apr 16 21:17:04 2022 Copyright (c) 1982, 2014, Oracle and/or its affiliates. All rights reserved. ADR base = "/u01/app/oracle" adrci>
先查看homepath是不是所要处理的日志目录
adrci> show home ADR Homes: diag/rdbms/orcl/orcl adrci>
如果不是,先设置homepath
adrci> set homepath diag/rdbms/orcl/orcl
清空警告日志,1440是按分钟算的,就是一天,这是清空一天以前的警告日志
adrci> purge -age 1440 -type alert
清空跟踪日志,1440是按分钟算的,就是一天,这是清空一天以前的跟踪日志
adrci> purge -age 1440 -type alert
