instantclient_12_1,在使用客户端连接oracle数据库时需要引入该文件夹下的oci.dll

用Navicat连接Oracle数据库时报错ORA-28547:connection to server failed, probable Oracle Net admin error . 多数是因为Navicat本地的OCI版本与Oracle服务器服务器不符造成的

oracle instantclient21.3版本

python连接oracle，使用cx_Oracle模块，模块版本和客户端版本不对应 python版本3.8 Oracle11 cx_Oracle 8.3 问题一.cx_Oracle.DatabaseError: DPI-1047: Cannot locate a 64-bit Oracle Client library: 解决一：添加如下代码，指定环境：os.environ['path'] = r'instantclient_10_2路径‘ 问题二：cx_Oracle.DatabaseError: DPI-1050: Oracle Client library is at version 10.2 but version 11.2 or higher is needed 解决二：因为我当前使用的是instantclient_10_2，应切换成instantclient_11_2,即添加如下代码：os.environ['path'] = r'instantclient_11_2路径'
