By default, the Interprocess Communication (IPC) memory choice is memory mapped. Complete the steps below to 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 Modifying twbcfg.ini.
  3. Remove the mmap directory:
    rm -rf mmap
The change does not require a kernel rebuild or a reboot.
