[suse-oracle] SLES9 with DB startup ORA-27125 unable to create shared
memory segment

Ronald Breuer



I install SLES9 + SP1 + DB + DB patch (software only)

I changed dbca as described in Metalink Note 292278.1

I got
SQL> startup
ORA-27125: unable to create shared memory segment
Linux Error: 1: Operation not permitted

I found Metalink Note 293988.1

With two 'workarounds'

--- Login as root
--- # echo 1 > /proc/sys/vm/disable_cap_mlock

This works for me

--- Login as root
--- Edit /etc/sysctl.conf
Add following lines
# Enable MLOCK?
# If you say yes here, Oracle will able to get require MLOCK priviledge
# for hugetlb memory.
--- Execute the command
/etc/boot.sysctl start
Setting current sysctl status from /etc/sysctl.conf
vm.disable_cap_mlock = 1
--- Dont forget to enable the service.
chkconfig boot.sysctl on

This did not work.
sysctl.conf is in /etc/sysconfig/sysctl.conf
The command an the syntax did not work for me.

How can I make this persistent?

With kind regards
