  • Edit this property on the database and on Unity, if used. Also see Coordinating Mechanism Property Values for Unity.
  • Use the default setting, if possible. Specify a value for the LdapClientTlsRandFile only when the default random number generator) is not available, or if you want to use another random number generator.
  • If the default is not available, you can install a copy of EGD or PRNGD every node, to provide a random number generator, and set the value of this property to the name of the EGD or PRNGD socket.
    The installed copy of EGD or PRNGD must have the same name on all Teradata Database nodes. See the EGD or PRNGD Readme file for details.
