配置oracleinstantclient、plsql连接数据库

首先安装pl\sql

https://developer.oracle.com/databases/database-for-python-developers-1

创建instantclient_12_2下的NETWORK下的ADMIN下的tnsnames.ora

 此为客户端配置

ORCL105 =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 169.254.13.91)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = orcl)

    )

  )

打开pl/sql先不登录，打开首选项

配置Oracle主目录和OCI库

登录发现中文乱码

配置变量名：NLS_LANG

变量值：SIMPLIFIED CHINESE_CHINA.ZHS16GBK

如果上述配置不成功

增加系统变量：

TNS_ADMIN=D:\instantclient_12_2\network\ADMIN

    ORACLE_HOME=D:\instantclient_12_2
