一、网友错误
pub上网友遇到一个问题
Tue Nov 22 10:31:19 2011 ALTER DATABASE MOUNT Tue Nov 22 10:31:19 2011 sculkget: failed to lock /u01/app/oracle/product/10.2.01/db_1/dbs/lkORCL exclusive sculkget: lock held by PID: 26308 Tue Nov 22 10:31:19 2011 ORA-09968: unable to lock file Linux Error: 11: Resource temporarily unavailable Additional information: 26308 Tue Nov 22 10:31:19 2011 ORA-1102 signalled during: ALTER DATABASE MOUNT...
我给的建议是重启数据库解决，其实重启数据库是关闭了当前开启的实例，然后开启报错的实例，所以重启成功
二、错误重现
