文档课题:迁移AUD$表至单独表空间. 应用场景:作为DBA肯定会遇到保留审计记录的需求,那么随时间的增加该表就会变得越来越庞大.而AUD$默认表空间为system,此时为了方便管理,通常是需要将AUD$表放到单独的表空间. 操作过程: -- 创建表空间 create tablespace AUD_TBS datafile '/u01/app/oracle/oradata/orcl/audit01.dbf' size 100M autoextend on;-- 迁移AUD$表 BEGIN DBMS_AUDIT_MGMT.set_audit_trail_location( audit_trail_type =>DBMS_AUDIT_MGMT.AUDIT_TRAIL_AUD_STD, audit_trail_location_value =>'AUD_TBS'); END; / -- 迁移FGA_LOG$ BEGIN DBMS_AUDIT_MGMT.set_audit_trail_location( audit_trail_type =>DBMS_AUDIT_MGMT.AUDIT_TRAIL_FGA_STD, audit_trail_location_value =>'AUD_TBS'); END; / -- 检查确认 set lines 168 pages 999 col segment_name for a30 col table_name for a18 col tablespace_name for a18 SELECT table_name, tablespace_name FROM dba_tables WHERE table_name IN ('AUD$', 'FGA_LOG$') ORDER BY table_name; col SEGMENT_NAME for a32 select TABLE_NAME, SEGMENT_NAME,TABLESPACE_NAME from dba_lobs where table_name in ('AUD$', 'FGA_LOG$'); 迁移前确认 > SELECT table_name, tablespace_name 2 FROM dba_tables 3 WHERE table_name IN ('AUD$', 'FGA_LOG$') 4 ORDER BY table_name; TABLE_NAME TABLESPACE_NAME ------------------ ------------------ AUD$ SYSTEM FGA_LOG$ SYSTEM > col SEGMENT_NAME for a32 > select TABLE_NAME, SEGMENT_NAME,TABLESPACE_NAME 2 from dba_lobs 3 where table_name in ('AUD$', 'FGA_LOG$'); TABLE_NAME SEGMENT_NAME TABLESPACE_NAME ------------------ -------------------------------- ------------------ FGA_LOG$ SYS_LOB0000000417C00013$$ SYSTEM FGA_LOG$ SYS_LOB0000000417C00028$$ SYSTEM AUD$ SYS_LOB0000000407C00040$$ SYSTEM AUD$ SYS_LOB0000000407C00041$$ SYSTEM 迁移后确认 > set lines 168 pages 999 > col segment_name for a30 > col table_name for a18 > col tablespace_name for a18 > SELECT table_name, tablespace_name 2 FROM dba_tables 3 WHERE table_name IN ('AUD$', 'FGA_LOG$') 4 ORDER BY table_name; TABLE_NAME TABLESPACE_NAME ------------------ ------------------ AUD$ AUD_TBS FGA_LOG$ AUD_TBS > col SEGMENT_NAME for a32 > select TABLE_NAME, SEGMENT_NAME,TABLESPACE_NAME 2 from dba_lobs 3 where table_name in ('AUD$', 'FGA_LOG$'); TABLE_NAME SEGMENT_NAME TABLESPACE_NAME ------------------ -------------------------------- ------------------ FGA_LOG$ SYS_LOB0000095317C00013$$ AUD_TBS FGA_LOG$ SYS_LOB0000095317C00028$$ AUD_TBS AUD$ SYS_LOB0000000407C00040$$ AUD_TBS AUD$ SYS_LOB0000000407C00041$$ AUD_TBS
