By default, the Interprocess Communication (IPC) memory choice is memory mapped. Complete the following steps 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 restart.
