Oracle Database Discussions

Hi,

We are using Oracle 11g R2(11.2.0.2) with ASM(AIX 6.1). We have four instances and four diskgroups. Recently we rebooted the server. We are not able to mount the databases after the reboot.

ASM instance is up and running and all the diskgroups are mounted.

When I try to startup the database, I am getting below error.

SQL> startup
ORACLE instance started.

Total System Global Area 5127602176 bytes
Fixed Size 2228512 bytes
Variable Size 4261416672 bytes
Database Buffers 855638016 bytes
Redo Buffers 8318976 bytes
ORA-00205: error in identifying control file, check alert log for more info

Here is the details from alert.log. I have tried many options like stop and start all the diskgroups and restarted ASM instances etc.. But nothing helped.

Pleaes let me know what could be the problem.
