— 获取表空间使用率
select used_percent into v_tablespace_used_percent
from tablespace_monitor
where tablespace_name = ‘USERS’ and rownum = 1;
— 计算推荐的表空间大小
select round((bytes + 1024*1024*1024) / 1024 / 1024, 2) into v_recommended_tablespace_mb
from dba_tablespaces
where tablespace_name = ‘USERS’;
— 如果表空间使用率超过80%,建议增加大小
if v_tablespace_used_percent > 80 then
dbms_output.put_line(‘Tablespace usage is ‘ || v_tablespace_used_percent || ‘%’);
dbms_output.put_line(‘Recommended tablespace size: ‘ || v_recommended_tablespace_mb || ‘ MB’);
end if;
end optimize_tablespace;

# 2. 执行优化存储过程
SQL> set serveroutput on
SQL> exec optimize_tablespace;
Tablespace usage is 85%
Recommended tablespace size: 3072 MB
PL/SQL procedure successfully completed.
# 3. 应用优化建议
SQL> alter database datafile ‘/oracle/app/oracle/oradata/FGEDUDB/users01.dbf’ resize 4096M;
Database altered.
# 4. 启用表空间自动扩展
SQL> alter database datafile ‘/oracle/app/oracle/oradata/FGEDUDB/users01.dbf’ autoextend on maxsize 10240M;
Database altered.
# 5. 创建定时任务
