The default Interprocess Communication (IPC) memory choice is memory mapped. You can switch 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 Editing twbcfg.ini.
  3. Remove the mmap directory: rm -rf mmap
Teradata Parallel Transporter will use shared memory as the IPC memory choice.

The change does not require a kernel rebuild or a reboot.
