公司电脑无法连接数据库：错误提示:SQLSTATE = 08001

在SqlServer的配置工具选择项后选择SqlServer外围应用配置器，点击服务和连接的外围应用配置器超链接，启动类型选择自动。看看服务状态是否为启动，如果是直接确定就OK了，

如果不是点击下面的启动按钮试试。

$ oerr ora 1194

01194, 00000, "file %s needs more recovery to be consistent"

// *Cause: An incomplete recovery session was started, but an insufficient

// number of logs were applied to make the file consistent. The

// reported file was not closed cleanly when it was last opened by

// the database. It must be recovered to a time when it was not being

// updated. The most likely cause of this error is forgetting to

// restore the file from a backup before doing incomplete recovery.

// *Action: Either apply more logs until the file is consistent or restore

// the file from an older backup and repeat recovery.

ORA-1194错误一般是数据文件需要做更多的recovery *** 作，如果你有对应的归档重做日志文件redo archivelog 则可以尝试recover database；如果没有的话需要使用特殊恢复手段恢复，例如使用ORACLE PRM-DUL 数据恢复软件直接抽取其中数据来达到恢复目的。
