我与Oracle Express Edition有问题。我可以通过使用sqlplus打开并运行数据库中的命令,但后来我尝试使用SQL开发人员连接到数据库,但它不起作用。这很奇怪,因为我有很多其他远程Oracle数据库,我可以通过使用sql developer或其他工具如IDEA连接到它们。听众可能有问题吗?无法连接到Oracle Express Edition
当我尝试连接时,我得到超时连接到端口1521。
Connection to @myhost.company.com failed.

最后只是女巫并没有任何反应。
您需要发布错误。 – Ravi
连接到端口1521(这是侦听器的标准端口)超时。 –
你能发布错误的截图吗? – Ravi
