Not able to startup Database- getting "ORA-27121" error

KartiFeb 1 2012 — edited Feb 2 2012

Hi All,

When i try to start database it fails with the below error.

Enter user-name: sys as sysdba
Enter password:
Connected to an idle instance.

SQL> !echo $ORACLE_HOME
/glohd/Oracle10g/product/10.2.0/db_2

SQL> !echo $ORACLE_SID
ORATECH

SQL> !ls -al $ORACLE_HOME/bin/oracle
-rwsr-s--x 1 oracle dba 131619960 Nov 06 2007 /glohd/Oracle10g/product/10.2.0/db_2/bin/oracle

SQL> startup
ORA-27121: unable to determine size of shared memory segment
IBM AIX RISC System/6000 Error: 13: Permission denied
SQL>

I doubt on shared memory permission but im not clear on that. Below is the output of 'ipcs -a'

$ipcs -a |grep oracle
m 80740369 0xf80b125c rw-r--- oracle staff oracle staff 0 1610620928 21758186 17826150 14:30:12 14:46:02 11:39:05
$

Please help me to solve this :(

Thanks
Karti
