oracle instant client和plsql使用配置

PATH=d:\Oracle\instantclient_11_1

TNS_ADMIN=d:\Oracle\instantclient_11_1 
LD_LIBRARY_PATH=d:\Oracle\instantclient_11_1 
SQLPATH=d:\Oracle\instantclient_11_1 
nls_lang=simplified chinese_china.ZHS16GBK

环境变量配置完成后，需要拷贝tnsnames.ora文件到D:\Oracle\instantclient_11_2目录下。

tnsnames.ora文件可以从服务器端进行拷贝，也可手动进行编辑，例如

TEST =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.114.88)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = test)
    )
)
