This task is only required when the Interprocess Communication (IPC) method has been changed from the default (memory mapped) to shared memory.
- Log on as the root user.
- Change directory to the Teradata Parallel Transporter installation directory: cd TPT_install_directory
- Create the mmap directory and set the permissions to 777: mkdir mmap chmod 777 mmap
Teradata Parallel Transporter will use memory mapped as the IPC memory choice.
The change does not require a kernel rebuild or a reboot.
