ORACLE擴容方法

先查詢表空間在物理磁盤上存放的位置,注意使用sysdba的帳號登錄。

SELECT tablespace_name, 
file_id, 
file_name, 
round(bytes / (1024 * 1024), 0) total_space 
FROM dba_data_files 
ORDER BY tablespace_name;

 

2. 須要擴容的表空間是DW_STG_TBS,目前的文件分配序號是DW_STG_TBS20.dbf，

    因此在接下來的要增長的文件的名稱從21開始，咱們一次行增長20個文件，腳本以下。

    其中設置的每一個文件初始分配空間爲7g, autoextend on爲自動增加大小，oracle單個文件大小最大不超過32g.
