Weblogic上的连接重置错误

Question

在我的公司中，当我尝试将 weblogic 连接到数据库时，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，我收到该错误

    Error encountered:

所以我将 SID 更改为无效的 SID 并得到该错误

我发现我与数据库的连接正常

我在我公司的其他服务器和带有 JDK 8 的 Weblogic 12c 上尝试过，再次出现“连接重置”错误

我在 Windows 操作系统上尝试本地 Weblogic 并获得成功 所以......我该怎么办

Answer 1

请您检查一下，例如：

• 当您尝试测试时从控制台连接成功
  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。
• 您在生产中使用的驱动程序是什么？ 和你的 Windows PC 一样吗？
• 这是每次都发生还是间歇性问题？
