Configuring ODBC Connectivity

You can configure ODBC connectivity to a Teradata database.

The following steps provide a guideline for configuring ODBC connectivity. For specific instructions, see the database documentation.

To configure connectivity for the integration service process, log in to the machine as a user who can start a service process.

Set the TERADATA_HOME, ODBCHOME, and PATH environment variables.

TERADATA_HOME
. Set the variable to the Teradata driver installation directory. The defaults are as follows:

Using a Bourne shell:

$ TERADATA_HOME=/opt/teradata/client/<version>; export TERADATA_HOME

Using a C shell:

$ setenv TERADATA_HOME /opt/teradata/client/<version>

ODBCHOME
. Set the variable to the ODBC installation directory. For example:

Using a Bourne shell:

$ ODBCHOME=$INFA_HOME/ODBC<version>; export ODBCHOME

Using a C shell:

$ setenv ODBCHOME $INFA_HOME/ODBC<version>

PATH
. To run the ddtestlib
utility, to verify that the DataDirect ODBC driver manager can load the driver files, set the variable as follows:

Using a Bourne shell:

PATH="${PATH}:$ODBCHOME/bin:$TERADATA_HOME/bin"

Using a C shell:

$ setenv PATH ${PATH}:$ODBCHOME/bin:$TERADATA_HOME/bin

Set the shared library environment variable.

The Teradata software contains multiple shared library components that the integration service process loads dynamically. Set the shared library environment variable so that the services can find the shared libraries at run time.

The shared library path must also include installation directory of the Informatica service

(server_dir)

Set the shared library environment variable based on the operating system.

The following table describes the shared library variables for each operating system:

Operating System	Variable
Linux	LD_LIBRARY_PATH
AIX	LIBPATH

For example, use the following syntax for Linux:

Using a Bourne shell:

$ LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:$HOME/server_dir:$ODBCHOME/lib:

$TERADATA_HOME/lib64:$TERADATA_HOME/odbc_64/lib"; 

export LD_LIBRARY_PATH

Using a C shell:

$ setenv LD_LIBRARY_PATH "${LD_LIBRARY_PATH}:$HOME/server_dir:$ODBCHOME/lib:$TERADATA_HOME/lib64:

$TERADATA_HOME/odbc_64/lib"

For AIX

Using a Bourne shell:

$ LIBPATH=${LIBPATH}:$HOME/server_dir:$ODBCHOME/lib:$TERADATA_HOME/lib64:$TERADATA_HOME/odbc_64/lib; export LIBPATH

Using a C shell:

$ setenv LIBPATH ${LIBPATH}:$HOME/server_dir:$ODBCHOME/lib:$TERADATA_HOME/lib64:

$TERADATA_HOME/odbc_64/lib

Edit the existing odbc.ini file or copy the odbc.ini file to the home directory and edit it.

This file exists in $ODBCHOME directory.

$ cp $ODBCHOME/odbc.ini $HOME/.odbc.ini

Add an entry for the Teradata data source under the section [ODBC Data Sources] and configure the data source.

For example, for Teradata Parallel Transporter utilities:

TERADATA_DSN=DataDirect 7.1 Teradata
[TERADATA_DSN]
Driver=/opt/teradata/client/<version>/lib64/tdataodbc_sb64.so
Description=NCR 3600 running Teradata V1R5.2
DBCName=<hostname>
LastUser=
Username=
Password=
Database=
DefaultDatabase=
UseNativeLOBSupport=Yes
CharacterSet=UTF8
SessionMode=ANSI

Set the DateTimeFormat to AAA in the Teradata data ODBC configuration.

Optionally, set the SessionMode to ANSI. When you use ANSI session mode, Teradata does not roll back the transaction when it encounters a row error.

If you choose Teradata session mode, Teradata rolls back the transaction when it encounters a row error. In Teradata mode, the integration service process cannot detect the rollback, and does not report this in the session log.

To configure connection to a single Teradata database, enter the DefaultDatabase name. To create a single connection to the default database, enter the user name and password. To connect to multiple databases, using the same ODBC DSN, leave the DefaultDatabase field empty.

For more information about Teradata connectivity, see the Teradata ODBC driver documentation.

Verify that the last entry in the odbc.ini is InstallDir and set it to the odbc installation directory.

For example:

InstallDir=<Informatica installation directory>/ODBC<version>

Edit the .cshrc or .profile to include the complete set of shell commands.

Save the file and either log out and log in again, or run the source command.

Using a Bourne shell:

$ source .profile

Using a C shell:

$ source .cshrc

For each data source you use, make a note of the file name under the Driver=<parameter> in the data source entry in odbc.ini. Use the ddtestlib
utility to verify that the DataDirect ODBC driver manager can load the driver file.

For example, if you have the driver entry:

Driver=/u01/app/teradata/td-tuf611/odbc/drivers/tdata.so

run the following command:

ddtestlib /u01/app/teradata/td-tuf611/odbc/drivers/tdata.so
