Replicate DB2 Data to Multiple Databases


Replicate DB2 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 DB2 integrates live DB2 data into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote DB2 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 DB2 data to one or many databases without any need to change your configuration.

Connect to DB2 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>Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test;</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>Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test;</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> </CDataSync>

Set the following properties to connect to DB2:

  • Server: Set this to the name of the server running DB2.
  • Port: Set this to the port the DB2 server is listening on.
  • Database: Set this to the name of the DB2 database.
  • User: Set this to the username of a user allowed to access the database.
  • Password: Set this to the password of a user allowed to access the database.

You will also need to install the corresponding DB2 driver:

  • Windows: Install the IBM Data Server Provider for .NET.

    On Windows, installing the IBM Data Server Provider is sufficient, as the installation registers it in the machine.config.

  • Java: Install the IBM Data Server Driver for JDBC.

    In the Java version, place the IBM Data Server Driver JAR in the www\WEB-INF\lib\ folder for this application.

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 DB2 API. The statement below caches and incrementally updates a table of DB2 data:

REPLICATE Orders;

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

DB2Sync.exe -g MySQLiteConfig.xml -f DB2Sync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar DB2Sync.jar -g MySQLiteConfig.xml -f DB2Sync.sql
