This task is only required when the Interprocess Communication (IPC) method has been changed from the default (memory mapped) to shared memory.
  1. Log on as the root user.
  2. Change directory to the Teradata Parallel Transporter installation directory:
    cd TPT_install_directory
    The path is specified in Modifying twbcfg.ini.
  3. 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.
