ORA-10997: Another startup/shutdown operation of this instance in progress Solution

I want to learn about Oracle and open the database tonight:

SQL> startup
ORA-10997: Another startup/shutdown operation of this instance inprogress
ORA-09967: Unable to create or open lock file

Linux error: 13: Permission denied

Baidu and Google have been using many methods on the Internet for a long time, so they are stuck in the water, so they have to try dbca again.

However, there is no way to survive, and finally we can see a method on OTN:

Root @ think-V30SA :~ # Chown-r ORACLE: DBA/u01/APP/Oracle/

oracle@think-V30SA:~$ sqlplus /nologSQL*Plus: Release 10.2.0.1.0 - Production on Wed Oct 17 19:28:51 2012Copyright (c) 1982, 2005, Oracle.

I finally succeeded, and the culprit was the permission. Alas .....
