Automated Continuous Google Cloud Storage Replication to IBM DB2

Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live Google Cloud Storage data into your IBM DB2 instance, allowing you to consolidate all of your data into a single location for archiving, reporting, analytics, machine learning, artificial intelligence and more.

Configure IBM DB2 as a Replication Destination

Using CData Sync, you can replicate Google Cloud Storage data to IBM DB2. To add a replication destination, navigate to the Connections tab.

1. Click Add Connection.
2. Select the Destinations tab and locate the IBM DB2 connector.
3. Click the Configure Connection icon at the end of that row to open the New Connection page. Sync requires the db2jcc.jar driver to connect to your DB2 database. If you have not done so already, make sure to download the native DB2 JDBC driver from DB2 JDBC Driver Versions and Downloads web page.
4. Copy the JDBC driver into the lib directory.
   • Microsoft Windows: C:\Program Files\CData\CData Sync\lib
   • UNIX or Mac OS X: ~/CData/CData Sync/lib
5. To connect to IBM DB2, set the following connection properties:
   • Connection Name: Enter a connection name of your choice for the IBM DB2 connection.
   • Server: Enter either the host name or the IP address of the server that hosts your IBM DB2 instance.
   • Port: Enter the port number of the server that hosts your instance of IBM DB2. The default port value is 50000.
   • Database: Set this to the database you want to read from and write to.
   • User: Set this to the database user.
   • Password: Set this to the user's password.

6. Once connected, click Create & Test to create, test and save the connection.

You are now connected to IBM DB2 and can use it as both a source and a destination.

NOTE: You can use the Label feature to add a label for a source or a destination.

In this article, we will demonstrate how to load Google Cloud Storage data into IBM DB2 and utilize it as a destination.

Configure the Google Cloud Storage Connection

You can configure a connection to Google Cloud Storage from the Connections tab. To add a connection to your Google Cloud Storage account, navigate to the Connections tab.

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

   The Google Cloud Storage source connector supports OAuth, OAuth PKCE, OAuth JWT, and GCP Instance Account authentication.

   OAuth (User Account)

   To connect with OAuth custom credentials, set the following properties:

   • Auth Scheme: Select OAuth.
   • OAuth Version: Select the version of OAuth you want to use. The default version is 2.0.
   • (Optional) Scope: Specify the scope of your access to the application.
   • (Optional) OAuth Authorization URL, OAuth Access Token URL, OAuth Refresh Token URL: Override the default endpoints if needed.

   When you connect, the Google Cloud Storage OAuth endpoint opens in your default browser. Log in and grant permissions, then the OAuth flow completes.

   OAuth JWT (Service Account)

   For silent authentication or delegated organization-wide access, create a service account in Google Cloud, grant it the required permissions on your bucket or project, register a custom OAuth application, and download the certificate file (.p12 or .pfx). Then set:

   • Auth Scheme: Select OAuthJWT.
   • OAuth JWT Cert: Path to your JWT certificate store.
   • OAuth JWT Cert Type: Type of key store. The default is PEMKEY_BLOB.
   • OAuth Client Id and OAuth Client Secret: Values from your registered OAuth application.
   • (Optional) OAuth JWT Cert Password, OAuth JWT Cert Subject, OAuth JWT Subject, OAuth JWT Subject Type, OAuth JWT Public Key Id: For delegated access and certificate configuration.

   For OAuth PKCE and GCP Instance Account methods, refer to the Help documentation.

   
4. Click Connect to Google Cloud Storage to ensure that the connection is configured properly.
5. Click Save & Test to save the changes.

Configure Replication Queries

CData Sync enables you to control replication with a point-and-click interface and with SQL queries. For each replication you wish to configure, 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, navigate to the Task tab in the Job, click Add Tasks, choose the table(s) from the list of Google Cloud Storage tables you wish to replicate into IBM DB2, and click Add Tasks again.

Customize Your Replication

You can use the Columns and Query tabs of a task to customize your replication. The Columns tab allows you to specify which columns to replicate, rename the columns at the destination, and even perform operations on the source data before replicating. The Query tab allows you to add filters, grouping, and sorting to the replication with the help of SQL queries.

Schedule Your Replication

Select the Overview tab in the Job, and click Configure under Schedule. You can schedule a job to run automatically by configuring it to run at 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 your Google Cloud Storage data to IBM DB2.

Run the Replication Job

Once all the required configurations are made for the job, select the Google Cloud Storage table you wish to replicate and click Run. After the replication completes successfully, a notification appears, showing the time taken to run the job and the number of rows replicated.
