问题描述
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.
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.
过去，偶尔在连接时会收到错误消息从读取呼叫中得到负号.供应商代码0
In the past, occasionally, when connecting, I get a error messageGot a minus one from a read call.Vendor Code 0
如果我重新启动，它就会消失.另一个朋友建议改变对他有用的转发端口.
If I do a reboot, it goes away. Another friend suggested changed the forwarding port which worked for him.
我最近升级到一台新计算机，现在看来我一直在收到错误消息.重新启动或更改转发端口根本没有帮助.
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.
端口转发脚本包含这样的内容
The port forwarding script contains something like this
putty -L (port):(machine name):1521
有人有什么主意吗?谢谢.
Does anybody have any idea? Thanks.
推荐答案
我的端口转发脚本转发多个端口.不知何故将它们分成2个较小的文件，该错误消失了.
My port forwarding script forwards multiple ports. Somehow separating them into 2 smaller file, this error went away.
