Oracle Database的基本操作——创建表空间，用户，授权。。。

关于SQL Plus连接Oracle数据库
1. 图形界面的SQL Plus的Host String。
Host String=[hostname(ip):port/ServiceName]
 
例如本机的Host String可能就是127.0.0.1:1521/orcl OR localhost:1521/orcl
 
2. 命令行连接数据库
 
 
>sqlplus [system/orcl@127.0.0.1:1521/orcl]
 
3. Oracle Net Manager创建Service Naming时创建的tnsnames.ora：
 
 
# tnsnames.ora Network Configuration File: F:/oracle/product/10.2.0/db_1/NETWORK/ADMIN/tnsnames.ora
# Generated by Oracle configuration tools.
 
service_name =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = host_name)(PORT = port_name))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = service_name)
    )
  )
 
ORCL =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = host_name)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = orcl)
    )
  )
 
EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )
 
 
 
 
1. 创建表空间
 
 
SQL> CREATE TABLESPACE oob
      2  DATAFILE 'F:/oracle/data/sm711_oob.dbf'
      3  SIZE 250M
      4  AUTOEXTEND ON NEXT 50M
      5  MAXSIZE UNLIMITED;
 
2. 创建用户
 
 
SQL> CREATE USER oob
      2  IDENTIFIED BY "oob"
      3  DEFAULT TABLESPACE oob;
 
 
3. 授权
 
SQL> GRANT CONNECT, RESOURCE, DBA TO oob;
 
4. 查询记录
 
SQL> SELECT type FROM infooldm1 WHERE type LIKE 'scdb.system';
 
5. 删除记录
 
SQL> DELETE FROM infooldm1 WHERE type LIKE 'scdb.system';
 
6. 删除表空间
 
DROP TABLESPACE nsn INCLUDING CONTENTS;
