During installation, the Teradata Parallel Transporter Base package checks for the system kernel values.
|Maximum number of semaphore sets in entire system.
|Maximum number of semaphores in entire system.
|Maximum number of processes that can have undo operations pending on semaphores
|Maximum size of a shared memory segment.
|Maximum number of shared memory segments in entire system.
|Maximum number of shared memory segments per process.
Checked only on Oracle Solaris 8.
The Teradata Parallel Transporter Base installation does not support formula value. If the kernel value is a formula, then the Teradata Parallel Transporter Base installation displays a warning message.
Start to install a Teradata Parallel Transporter product.
If the system does not meet the required minimum value, the Teradata Parallel Transporter installation prompts to increase the value to the minimum required value.
Warning: The current value of 1048675 for the kernel parameter (SHMMAX) is less than the minimum required value of 4194304. SHMMAX refers to the maximum size of a shared memory segment. Note: This install recommends increasing the value to the minimum required value. Note: A kernel rebuild is not required to make the kernel parameter change(s) effective. Note: A reboot is required to make the kernel parameter change(s)effective. The reboot can be done after this installation but before running Teradata Parallel Transporter jobs. Do you want to increase the value to the minimum required value for the above kernel parameter(s)? Please enter y for yes or n for no [y,n,? (default : y)]
- At the prompt, enter n to keep the current kernel value or press Enter to change the kernel value (this is the default). A reboot is required to make the kernel parameter changes effective.
- Log on as root user to reboot the system. The reboot can be done after all the installations, but must be done before running a Teradata Parallel Transporter job.
The following reboot command reboots the system in 60 seconds:
cd /usr/sbin/shutdown -y -g60 -i6
