Oracle Database Discussions

I found that my database was down this morning.

While stating up the database I got this message -

SQL> startup;
ORA-10997: another startup/shutdown operation of this instance inprogress
ORA-09967: unable to create or open lock file
IBM AIX RISC System/6000 Error: 89: Invalid file system control data detected

While checking the alert log, I am getting these error in the Alert Log -

Can you tell me what should be done to overcome this issue.

Thanks!
