从 read 调用中得到负一
我使用 SQL Developer 连接到具有只读访问权限的数据库。这是 TNS 连接。我使用 tnsnames.ora、转发端口脚本和 SQL Developer。
过去,连接时偶尔会收到错误消息 从 read 调用中得到负一。 供应商代码 0
如果我重新启动,它就会消失。另一位朋友建议更改对他有用的转发端口。
我最近升级到了一台新计算机,现在似乎我不断收到错误消息。重新启动或更改转发端口根本没有帮助。
端口转发脚本包含类似这样的内容
putty -L (port):(machine name):1521
有人知道吗?谢谢。
I connect to a database with read only access using SQL developer. It's a TNS connection. I use a tnsnames.ora, forwarding port script and SQL Developer.
In the past, occasionally, when connecting, I get a error message
Got a minus one from a read call.
Vendor Code 0
If I do a reboot, it goes away. Another friend suggested changed the forwarding port which worked for him.
I recently upgraded to a new computer and now it seems that I am getting the error message consistently. Reboot or changing forwarding port does not help at all.
The port forwarding script contains something like this
putty -L (port):(machine name):1521
Does anybody have any idea? Thanks.

我的端口转发脚本转发多个端口。以某种方式将它们分成两个较小的文件,这个错误就消失了。
My port forwarding script forwards multiple ports. Somehow separating them into 2 smaller file, this error went away.
检查您的 sqlnet.ora 文件并注释是否有如下所示的任何条目。
现在重新加载您的侦听器并检查 SQL Developer 的连接。
Check your sqlnet.ora file and comment if there is any entry like the below.
Now reload your listener and check the connectivity from SQL Developer.
