Replicate Multiple DB2 Accounts

CData Sync is a stand-alone application that provides solutions for a variety of replication scenarios such as replicating sandbox and production instances into your database. CData Sync includes a web-based interface that makes it easy to manage multiple DB2 connections. In this article we show how to use the web app to replicate multiple DB2 accounts to a single database.

Configure the Replication Destination

Using CData Sync, you can replicate DB2 data to any number of databases, both cloud-based and on-premises. To add a replication destination, navigate to the Connections tab.

1. Click Add Connection.
2. Select a destination and enter the necessary connection properties. In this article, we use SQLite.
3. Enter the necessary connection properties. To replicate DB2 to a SQLite database, enter a file path in the Data Source box.
4. Click Test Connection to ensure that the connection is configured properly.
5. Click Save Changes.

Configure DB2 Connections

You can configure connections to DB2 from the Connections tab. To add a connection to one of your DB2 accounts, navigate to the Connections tab. For each DB2 account you wish to replicate, do the following:

1. Click Add Connection.
2. Select a source (DB2).
3. Configure the connection properties.
   
   

   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.

4. Click Connect to ensure that the connection is configured properly.
5. Click Save Changes.

Configure Queries for Each DB2 Instance

CData Sync enables you to control replication with a point-and-click interface and with SQL queries. To configure a replication, navigate to the Jobs tab and click Add Job. Select the Source and Destination for your replication.

Replicate Entire Tables

To replicate an entire table, click Add Tables in the Tables section, choose the table(s) you wish to replicate, and click Add Selected Tables.

Customize Your Replication

You can use a SQL query to customize your replication. 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. To customize your replication, click Add Custom Query in the Tables section and define the Query Statement.

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

REPLICATE Orders;

You can specify a file containing the replication queries you want to use to update a particular database. Separate replication statements with semicolons. The following options are useful if you are replicating multiple DB2 accounts into the same database:

• Use a different table prefix in the REPLICATE SELECT statement:

  REPLICATE PROD_Orders SELECT * FROM Orders;

• Alternatively, use a different schema:

  REPLICATE PROD.Orders SELECT * FROM Orders;

Schedule Your Replication

In the Schedule section, you can schedule a job to run automatically, configuring the job to run after specified intervals ranging from once every 10 minutes to once every month.

Once you have configured the replication job, click Save Changes. You can configure any number of jobs to manage the replication of the data from your different DB2 accounts.
