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
