Replicate Teradata Data to Multiple Databases


Replicate Teradata data to disparate databases with a single configuration.

Always-on applications rely on automatic failover capabilities and real-time access to data. CData Sync for Teradata integrates live Teradata data into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote Teradata data from Windows or any machine running Java.

You can use Sync's command-line interface (CLI) to easily control almost all aspects of the replication. You can use the CLI to replicate Teradata data to one or many databases without any need to change your configuration.

Connect to Teradata Data

You can save connection strings and other settings like email notifications in XML configuration files.

The following example shows how to replicate to SQLite.

Windows

<?xml version="1.0" encoding="UTF-8" ?> <CDataSync><DatabaseType>SQLite</DatabaseType> <DatabaseProvider>System.Data.SQLite</DatabaseProvider> <ConnectionString>User=myuser;Password=mypassword;Server=localhost;Database=mydatabase;</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> <TaskSchedulerStartTime>09:51</TaskSchedulerStartTime> <TaskSchedulerInterval>Never</TaskSchedulerInterval> </CDataSync>

Java

<?xml version="1.0" encoding="UTF-8" ?> <CDataSync><DatabaseType>SQLite</DatabaseType><DatabaseProvider>org.sqlite.JDBC</DatabaseProvider> <ConnectionString>User=myuser;Password=mypassword;Server=localhost;Database=mydatabase;</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> </CDataSync>

To connect to Teradata, provide authentication information and specify the database server name.

  • User: Set this to the username of a Teradata user.
  • Password: Set this to the password of the Teradata user.
  • DataSource: Specify the Teradata server name, DBC Name, or TDPID.
  • Port: Specify the port the server is running on.
  • Database: Specify the database name. If not specified, the default database is used.

Configure Replication Queries

Sync enables you to control replication with standard SQL. The REPLICATE statement is a high-level command that caches and maintains a table in your database. You can define any SELECT query supported by the Teradata API. The statement below caches and incrementally updates a table of Teradata data:

REPLICATE NorthwindProducts;

You can specify a file containing the replication queries. This enables you to use the same replication queries to replicate to several databases.

Run Sync

After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:

Windows

TeradataSync.exe -g MySQLiteConfig.xml -f TeradataSync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar TeradataSync.jar -g MySQLiteConfig.xml -f TeradataSync.sql
