一次 备库aud$增大导致空间不足的现象

今天接到报警短信 说 /oracle/目录空间不足

查看发现 sysaux 数据文件很大，怀疑是默认的审计没关，查看aud$ 果真很大

是从dg主库同步过来的数据。

清空：

sys@test>begin

2 dbms_audit_mgmt.init_cleanup(

3 audit_trail_type => dbms_audit_mgmt.audit_trail_db_std,

4 default_cleanup_interval => 24 );

5 end;

7 /

执行报错

ERROR at line 1:

ORA-46267: Insufficient space in 'SYSAUX' tablespace, cannot complete operation

ORA-06512: at "SYS.DBMS_AUDIT_MGMT", line 1087

ORA-06512: at line 2

直接truncate table sys.aud$ reuse storage;

alter table sys.aud$ deallocate unused keep 8640m;

alter table sys.aud$ deallocate unused keep 7000m;

alter table sys.aud$ deallocate unused keep 6000m;

...

alter table sys.aud$ deallocate unused keep 10m;

truncate过程1-2分钟之内结束，最后sys.aud$变成10M。
