InstantClient安装使用

因oracle应用程序及其工具toad、PLSQL Developer等的部署很多,动辙要安装几百兆的Oracle Client实在很烦。

Instant client小而够用。这里共享出自己的经验，供同行参考，如果能给你帮助，荣幸之至。

 

运行环境：windows XP sp3，新安装系统，从未安装过任何版本Oracle

 

1、下载Instant Client

http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html

 

找到与系统对应版本下载。

 

这里以32位windows系统：

instantclient-basic-nt-11.2.0.3.0.zip

instantclient-sqlplus-nt-11.2.0.3.0.zip

 

如果你只用客户端工具，不使用命令行下sqlplus，第二个包可以不用

 

2、解压缩包到C:\instantclient_11_2

 

3、设置变量：

NLS_lANG=SIMPLIFIED CHINESE_CHINA.ZHS16GBK（注意中间有空格，这个如果不设，toad查询中文会是乱码）

TNS_ADMIN=C:\instantclient_11_2

Path=C:\instantclient_11_2

 

4、保存以下内容为注册表文件，导入注册表（路径部分，请自己修改）

 

Windows Registry Editor Version 5.00

 

[HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_OraClient10g_home]

"NLS_LANG"="SIMPLIFIED CHINESE_CHINA.ZHS16GBK"

"ORACLE_BUNDLE_NAME"="Enterprise"

"ORACLE_GROUP_NAME"="Oracle - OraClient10g_home"

"ORACLE_HOME"="C:\\instantclient_11_2"

"ORACLE_HOME_KEY"="SOFTWARE\\ORACLE\\KEY_OraClient10g_home"

"ORACLE_HOME_NAME"="OraClient10g_home"

 

5、建立tnsnames.ora，并保存到安装目录：C:\instantclient_11_2

 

这个这里就不多说了

 

# tnsnames.ora Network Configuration File: D:\oracle\product\10.2.0\client_1\network\admin\tnsnames.ora

# Generated by Oracle configuration tools.

 

ORCL =

   (DESCRIPTION =

     (ADDRESS_LIST =

       (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

     )

     (CONNECT_DATA =

       (SERVICE_NAME = orcl)

 

 

6、测试：

C:\Documents and Settings\Administrator>sqlplus /nolog

 

SQL*Plus: Release 11.2.0.3.0 Production on 星期六 4月 28 10:10:10 2012

 

Copyright (c) 1982, 2010, Oracle.  All rights reserved.

 

SQL> conn scott/tiger@orcl

已连接。

SQL>

 

至此，安装已经完成。toad、PLSQL Developer等工具，以及应用软件都可以正常使用了。

我发现本地装的数据库连不上，局域网的连上了

# tnsnames.ora Network Configuration File: E:\Oracle\Database11g\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

ORCL-10.8 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.10.8)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = orcl)
    )
  )

ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

10.8的能脸上，可是127.0.0.1的连不上

你之所以连不上，是因为你SERVICE_NAME = orcl重复了，出现了两次，是不是这个原因啊？
