instantclient 10.2 客户端配置

instantclient_10_2客户端配置

1.下载Oracle Client Package .
从http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/winsoft.html下载
Instant Client Package – Basic包( 标注:All files required to run OCI, OCCI, and JDBC-OCI applications)这里下载的是Version 10.2.0.4
2.本地保存Oracle Client Package:
创建文件夹,比如oracle_client,将下载的文件加压缩到此文件夹里.(笔者目录: D:\oracle_client\instantclient_10_2)
3.在当前目录下,手动配置sqlnet.ora和tnsnames.ora
比如这里是:
sqlnet.ora文件内容:
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
tnsnames.ora文件内容(斜体表示需要替换的内容):
jcms=
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.230)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = viewline)
    )
)
4.配置环境变量

4.1 变量名: TNS_ADMIN
变量值: G:\config\oracle_client\instantclient_10_2\network\admin
否则出现:ORA-12154: TNS:could not resolve the connect identifier specified错误
如果之前安装了Oracle 又卸载,会遗留NLS_LANG=NA的键值.输入RegEdit打开注册表HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE.在右面找到NLS_LANG=NA并删除掉
否则会报ORA-12705: Cannot access NLS data files or invalid 错误.

4.2 变量名: NLS_DATE_FORMAT
值:YYYY-MM-DD HH24:MI:SS

4.3 变量名: NLS_LANG
值:SIMPLIFIED CHINESE_CHINA.ZHS16GBK


5.安装pl/sql软件(过程略)

6.配置pl/sql的Oracle连接参数:
选择pl/sql的工具/首选项(too/ preference/)里的连接,在右面设置Oracle主目录名(即安装目录)和OCI库.
Oracle主目录名: D:\oracle_client\instantclient_10_2
OCI库: D:\oracle_client\instantclient_10_2\oci.dll
7.自动登陆pl/sql
快捷方式后加 userid=name/pswd@servicename
"D:\Program Files\PLSQL Developer\plsqldev.exe" userid=name/pswd@orcl229
