The Teradata Parallel Transporter Base installation checks
the values of the shared memory parameters for the required minimum values. If the value for a
shared memory parameter is less than the minimum value, the installation recommends increasing
the value to the minimum value.
The shmmni parameter determines the system-wide limit on the number of shared memory segments that can be created.
The shmmax parameter determines the maximum size of a shared memory segment. The minimum value is 4194304.
- Log on as the root user.
-
Check the value of the shmmni parameter; the minimum value is
200:
/sbin/sysctl kernel.shmmni
-
Add the following line in the /etc/rc.d/rc.local file to increase the
shmmni parameter value to 200:
echo 200 > /proc/sys/kernel/shmmni
-
To shut down the system in one minute, type:
/sbin/shutdown -r +1
