免安装oracle客户端设置
1.下载Oracle Client Package .
从?
tnsnames.ora文件内容(斜体表示需要替换的内容):
orcl=
(DESCRIPTION =
??? (ADDRESS_LIST =
????? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.103)(PORT = 1521))
??? )
??? (CONNECT_DATA =
????? (SERVICE_NAME = orcl)
??? )
)
?
4.配置环境变量
变量名: TNS_ADMIN
变量值: D:\oracle_client\instantclient_10_2
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.
?
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/Oracle主目录名: D:\oracle_client\instantclient_10_2
OCI库: D:\oracle_client\instantclient_10_2\oci.dll
7.登陆pl/sql测试成功
