python使用cx_Oracle连接timesten

环境:

OS:Windows

DB:18.1

1.配置环境变量
TNS_ADMIN=C:\TimesTen\tt181_64\network\admin

2.创建tnsnames.ora文件
在timesten安装目录下
C:\TimesTen\tt181_64\network\admin\samples
拷贝一个tnsnames.ora到C:\TimesTen\tt181_64\network\admin进行修改

3.修改tnsnames.ora
C:\TimesTen\tt181_64\network\admin\tnsnames.ora

添加如下内容:

mytest = (DESCRIPTION =
              (CONNECT_DATA =
                (SERVICE_NAME = timesten_dns)
                (SERVER = timesten_client)))

这里的timesten_dns是在odbc里创建的odbc数据源

4.测试代码

#!/usr/bin/env python
#coding=utf-8
import os, json, urllib, datetime, shutil,random,uuid
from random import choice
import pymysql
import traceback
import time

import cx_Oracle
import pyodbc

def connect_timesten_db():
    connection = cx_Oracle.connect("hxl", "oracle", "mytest")
    cursor = connection.cursor()
    cursor.execute("insert into tb_test values (42,42)")
    connection.commit()
    connection.close()


if __name__ == '__main__':
    print("开始时间:"+time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time())))
    ##l_flag = insert_data_for_doris()
    l_flag=connect_timesten_db()
    print("结束时间:"+time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time())))
