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
The path is specified in Editing twbcfg.ini.

Teradata Parallel Transporter will use memory mapped as the IPC memory choice.
The change does not require a kernel rebuild or a reboot.
