Question

在我公司我在OEL 6.5上使用Weblogic 10.3.6.0连接到另一个位置的Oracle数据库，当我尝试连接weblogic到db时出现错误

    Error encountered:

所以我将SID更改为无效的SID并获得该错误

Error encountered:

        ... 7 more

从那里我发现我与数据库的连接没问题

我尝试使用我公司的其他服务器和使用JDK 8的Weblogic 12c并再次出现“连接重置”错误

我尝试使用Windows操作系统上的本地Weblogic并获得成功所以...我能做什么

Answer 1

请你检查一下这样的事情：

是您尝试测试时从控制台成功连接的数据源？
是否有任何防火墙限制您的数据库和Weblogic服务器之间的连接。
您正在使用的驱动程序是什么？是吗？和你的Windows PC一样吗？
每次都会发生这种情况还是间歇性问题？
