The following table describes the things to consider when using the LOGON command.

LOGON Usage Notes 
Topic Usage Notes
Logon Parameters For standard logon, the parameters (tdpid, username, password, and acctid) are used in all sessions established with the database. The LOGON command may occur only once.

For single sign-on, if the Gateway to the database is configured to use single sign-on (SSO), and are already logged on to a Teradata client machine, then the machine name, user name, and password are not required in the LOGON command. The user name and password combination which were specified logging onto a Teradata client machine are authenticated with network security for a single sign-on such that valid Teradata users will be permitted to log on to the database. The use of SSO is strictly optional, unless the Gateway has been configured to accept only SSO-style logons.

On z/OS, with the use of User Logon Exit routine in TDP, userid is not required. Otherwise, userid is required. For more information, see Teradata® Director Program Reference, B035-2416.

To connect to a database system other than the one currently logged onto, the tdpid must be included in the LOGON command. If the tdpid is not specified, the default contained in clispb.dat will be used. See Teradata® Call-Level Interface Version 2 Reference for Workstation-Attached Systems, B035-2418 for information about setting defaults.

To be interpreted correctly, the tdpid must be followed by the slash separator (‘/’), to distinguish the tdpid from a database user name. For example, to connect to serverxyz, enter one of the following:

.LOGON serverxyz/;

.LOGON serverxyz/,,'acctinfo';

If an account ID is to be used, the optional account ID must be specified in the LOGON command.

Using LOGON with the LOGTABLE Command Both the LOGON and LOGTABLE commands are required.

LOGON and LOGTABLE commands may appear in any order, but must precede other commands except RUN commands used to identify the file containing the LOGON command.

If the LOGON command is entered first, Teradata MultiLoad warns that the LOGTABLE command also is required.

  • When Teradata MultiLoad attempts to connect the Main SQL session the first time and the database is down, Teradata MultiLoad displays an error message and terminates.
  • When Teradata MultiLoad attempts to connect the Auxiliary SQL session, or the data sessions and the database is down. Teradata MultiLoad tries to connect 16 times; if the database is still down, Teradata MultiLoad displays an error message and terminates.
