Oracle數據庫新建表空間和對應用戶

Oracle數據庫新建表空間和對應用戶

1. 創建表空間和臨時表空間數據文件

   • 創建表空間數據文件

     SQL> CREATE TABLESPACE rec_news LOGGING DATAFILE '/home/oracle/OracleDB/user/rec_news/rec_news.dbf' SIZE 100M AUTOEXTEND ON NEXT 100M MAXSIZE 5120M EXTENT MANAGEMENT LOCAL;
     
     Tablespace created.
     

   • 創建臨時表空間數據文件

     SQL> CREATE TEMPORARY TABLESPACE rec_news_temp tempfile '/home/oracle/OracleDB/user/rec_news/rec_news_tmp.dbf' SIZE 100M AUTOEXTEND ON NEXT 50M MAXSIZE 1024M EXTENT MANAGEMENT LOCAL;
     
     Tablespace created.
     

2. 創建用戶與數據庫文件關聯

   SQL> CREATE USER rec IDENTIFIED BY <password> DEFAULT TABLESPACE rec_news TEMPORARY TABLESPACE rec_news_temp;
   
   User created.
   

3. 添加權限

   SQL> grant connect, resource, dba to rec;
   
   Grant succeeded.
   
   SQL> grant create session to rec;
   
   Grant succeeded.
   
   SQL> commit;
   
   Commit complete.
   

此時就可以以創建的用戶身份重新進入Oracle數據庫了。

以創建用戶身份進入sqlplus，執行：

[oracle@datanode1 ~]$ sqlplus

SQL*Plus: Release 11.2.0.1.0 Production on Fri Apr 6 17:56:53 2018

Enter user-name: rec
Enter password: 

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> select tablespace_name from user_tablespaces;

TABLESPACE_NAME
------------------------------
SYSTEM
SYSAUX
UNDOTBS1
TEMP
USERS
EXAMPLE
REC_NEWS
REC_NEWS_TEMP

8 rows selected.

可以看到查詢結果包含我們剛剛創建的兩個TABLESPACE。

問題記錄：

1. ORA-27040: file create error, unable to create file Linux-x86_64 Error: 13: Permission denied

   SQL> CREATE TABLESPACE rec_news LOGGING DATAFILE '/home/oracle/OracleDB/user/rec_news/rec_news.dbf' SIZE 100M AUTOEXTEND ON NEXT 100M MAXSIZE 5120M EXTENT MANAGEMENT LOCAL;
   CREATE TABLESPACE rec_news LOGGING DATAFILE '/home/oracle/OracleDB/user/rec_news/rec_news.dbf' SIZE 100M AUTOEXTEND ON NEXT 100M MAXSIZE 5120M EXTENT MANAGEMENT LOCAL
   *
   ERROR at line 1:
   ORA-01119: error in creating database file
   '/home/oracle/OracleDB/user/rec_news/rec_news.dbf'
   ORA-27040: file create error, unable to create file
   Linux-x86_64 Error: 13: Permission denied
   

   經查，/home/oracle/OracleDB/user/rec_news/目錄的所有者爲root:root，修改爲oracle:oinstall後即可以oracle用戶身份正常創建。
