数据库SYBASE11.92经常出现如下问题：

相解决但不知问题在哪里，各位大侠谁见过这种问题 呀？？？

期待中。。。
但对你的数据库启动没有影响吧

检查一下sybase所起端口，以及网络通信

hobbylu

用ribo这个工具,去跟踪你的数据库的登陆情况

新奇东东

  后来解决了吗？怎么解决的？我也遇到同样问题，造成应用程序无响应，但数据库入库正常，真是奇怪

Error 1621

Error message text
Type '%c' not allowed before login.

Explanation
Adaptive Server uses TDS (Tabular Data Stream) packets to communicate with clients. A token is attached to every TDS packet to differentiate between different types of packets. During login, Adaptive Server expects a client to supply either the TDS_LOGIN or TDS_ECHO token.
Error 1621 occurs when a client sends a token other than TDS_LOGIN or TDS_ECHO at login. Possible causes include:
1.Non-printing characters in the login script.
2.Another process trying to access the port used by the server.
3.An incompatible database driver; for example, an unsupported ODBC driver.

不过还是建议各位习惯使用sybook
