oracle 表空间数据文件最大值的计算测试

2022-07-08 14:37:00  阅读:52  来源: 互联网

标签:racdg 最大值 dbf 空间数据 maxsize oradata oracle app u01


环境:centos7.6 +oracle 11.2.0.4 

数据安装是默认安装的

创建表空间语句参考官方sql文挡

测试单个表空间最大可创建多少个数据文件,plsql 如下:

declare 
str varchar2(200);
begin
for i in 1..1000 loop
--DBMS_OUTPUT.PUT_LINE();
str:='alter tablespace T_SMALL01 add datafile '||''''||'/u01/app/oradata/racdg/T_SMALL0'||i||'.dbf'||''''||' size 1m autoextend on maxsize unlimited';
DBMS_OUTPUT.PUT_LINE(str);
EXECUTE IMMEDIATE str;
end loop;
end ;

  

操作执行如下,脚本for 循环值增加到1000,向表空间T_SMALL01添加数据文件 执行如下
