unable to attach to shared memory segment

unable to attach to shared memory segment

See here - script which reconfigure system to prevent it (drop . CONFIG.sh):

#!/bin/sh
. CONFIG.sh
#
# This script works around HUGETLB problem with some kernels
# Problem is that they are ON by default in SLES9
# but they require MCAP permission which is absent for Oracle
# So we will turn off mcap feature.
#
echo 1 > /proc/sys/vm/disable_cap_mlock

echo "vm.disable_cap_mlock = 1" >> /etc/sysctl.conf
chkconfig boot.sysctl on


Well known problem.

Subject: [suse-oracle] unable to attach to shared memory segment


Hi, I'm having a problem with my oracle installation in a x86_64
architecture.
Whenever I try to log in with sqlplus with the system user "oracle" and
database admin "sys" I can do so perfectly but if I want to use sqlplus with
another system's user like for example "oracleuser" and a user created in
oracle I get:

ORA-01034 (See ORA-01034.ora-code.com): ORACLE not available
ORA-27123 (See ORA-27123.ora-code.com): unable to attach to shared memory segment
Linux-x86_64 Error: 13: Permission denied

I have in this user's environmental variables:
ORACLE_SID=name_of_my_database
ORACLE_HOME=/opt/oracle/product/9ir2
ORACLE_BASE=/opt/oracle

Plus I have him associated to the "dba" group.

Odd thing is that I can log in using enterprise manager console with this
user,
I just can't log in using sqlplus. Can someone help me?

Jorge
