SharePlex 9.0.1 - Upgrade Guide

Teradata Setup (td_setup)

Overview

Run the Database Setup utility for Teradata (td_setup) on a Teradata system to establish a user account and database for use by SharePlex.

Supported databases

Teradata on supported platforms

Requirements for use

  • An ODBC Data Source Name (DSN) must exist for SharePlex to use. You will be prompted for this name during setup. See the Teradata ODBC documentation for instructions.
  • Run the setup utility on all target Teradata instances in the SharePlex replication configuration.
  • Within a server cluster, run the setup utility on the node to which the shared disk that contains the SharePlex variable-data directory is mounted.
  • For consolidated replication, run the setup utility for each variable-data directory on the Teradata target.

Required privileges

The setup utility must be run as a Teradata Administrator in order to grant SharePlex the required privileges to operate on the database and to create the SharePlex database account.

Run Database Setup for Teradata

  1. Shut down any running SharePlex processes and sp_cop on the target system.
  2. Run the td_setup program from the bin subdirectory of the SharePlex product directory.

    Important! If you installed the SharePlex instance on any port other than the default of 2100, use the ‑p option to specify the port number. For example, in the following command the port number is 9400.

    $/users/splex/bin> td_setup ‑p9400

Table 6: Setup Prompts and Responses

Prompt Response

Please enter the full directory path of the Teradata ODBC driver:

Enter the full path to the Teradata ODBC driver library. This step initializes the driver location within the setup utility so that the rest of the setup can take place. It requires a second running of the setup utility to complete the setup steps.

Please run td_setup again to create the tables, login and user accounts needed to run SharePlex replication.

Run the setup utility again, including the port number if you installed SharePlex on any port other than 2100:

$/users/splex/bin> td_setup -p9400

Enter the DSN name or connection string []:

Enter a connection string or a data source name (DSN) that connects to Teradata.

Enter the Teradata Administrator name:

Enter the name of the Teradata Administrator. This user will perform the work on the SharePlex account.

Enter the password for the Administrator account:

Enter the password of the Administrator.

Would you like to create a new SharePlex user [y]:

Press Enter to accept the default to create a new SharePlex database user account or enter n to use an existing SharePlex account.

Enter the name of the new SharePlex user:

(or...)

Enter the name of the existing SharePlex user:

Enter the name of the new or existing SharePlex user, depending on which option you chose in the previous step.

 

Enter the password for new SharePlex user:

(or...)

Enter the password for existing SharePlex user:

Enter the password of the new or existing SharePlex user account.

Re-enter the password for new SharePlex user:

This prompt is only shown if you created a new user. Enter the SharePlex password again.

Enter the name of the database:

Accept the default or enter a different name for the database.

Database name database does not exist. Would you like to create it? [y]:

If this prompt is displayed, the specified database does not exist. Press Enter to have the setup utility create it for you.

A successful setup terminates with a message similar to the following:

Completed SharePlex for Teradata database configuration

SharePlex User name: splex

Database name: splex

Target specification in SharePlex configuration: r.splex

Grant additional database privileges

The setup utility creates the following objects:

  • a database user by which SharePlex Post will operate (which also owns a database)
  • a database into which SharePlex can install its internal objects (which can be the database owned by the SharePlex Post user or a different one)

The setup utility then prompts you to specify any additional Teradata databases that you want to include as replication targets. For each of those databases, the utility issues the following grant to the SharePlex user:

grant all on database to SharePlex_user;
