关于 java 连接oracle的 Io 异常: Got minus one from a read call

kbqdftwtos

今日无意中用java连接oracle时，竟出现以下异常，甚是奇怪：
Caused by: java.sql.SQLException: Io 异常: Got minus one from a read call
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:179)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:333)
at oracle.jdbc.driver.OracleConnection.<init>(OracleConnection.java:404)
at oracle.jdbc.driver.OracleDriver.getConnectionInstance(OracleDriver.java:468)
at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:314)
....

问题在重新启动应用后，应用连接oracle时出错，无法启动应用。

最后重新启动oracle11g的服务，没有问题了，但是还没有找到具体原因。




后来在另外一台应用上也发现同样问题，发现问题的严重性，经过分析可能是驱动问题；在不重新启动oracle11g服务的情况下，替换最新版本的jdbc驱动包，问题解决；
