IBM Cloud Object Storage Reporting in OBIEE with the IBM Cloud Object Storage JDBC Driver

The CData JDBC Driver for IBM Cloud Object Storage is a standard database driver that can integrate real-time access to IBM Cloud Object Storage data into your Java-based reporting server. This article shows how to deploy the driver to Oracle Business Intelligence Enterprise Edition (OBIEE) and create reports on IBM Cloud Object Storage data that reflect any changes.

Deploy the JDBC Driver

Follow the steps below to add the JDBC driver to WebLogic's classpath.

For WebLogic 12.2.1, simply place the driver JAR and .lic file into DOMAIN_HOME\lib; for example, ORACLE_HOME\user_projects\domains\MY_DOMAIN\lib. These files will be added to the server classpath at startup.

You can also manually add the driver to the classpath: This is required for earlier versions. Prepend the following to PRE_CLASSPATH in setDomainEnv.cmd (Windows) or setDomainEnv.sh (Unix). This script is located in the bin subfolder of the folder for that domain. For example: ORACLE_HOME\user_projects\domains\MY_DOMAIN\bin.

Restart all servers; for example, run the stop and start commands in DOMAIN_HOME\bitools\bin.

Create a JDBC Data Source for IBM Cloud Object Storage

After deploying the JDBC driver, you can create a JDBC data source from BI Publisher.

1. Log into BI Publisher, at the URL http://localhost:9502/analytics, for example, and click Administration -> Manage BI Publisher.
2. Click JDBC Connection -> Add Data Source.
3. Enter the following information:
   • Data Source Name: Enter the name that users will create connections to in their reports.
   • Driver Type: Select Other.
   • Database DriverClass: Enter the driver class, cdata.jdbc.ibmcloudobjectstorage.IBMCloudObjectStorageDriver.
   • Connection String: Enter the JDBC URL.

     Register a New Instance of Cloud Object Storage

     If you do not already have Cloud Object Storage in your IBM Cloud account, follow the procedure below to install an instance of SQL Query in your account:

     1. Log in to your IBM Cloud account.
     2. Navigate to the page, choose a name for your instance and click Create. You will be redirected to the instance of Cloud Object Storage you just created.

     Connecting using OAuth Authentication

     There are certain connection properties you need to set before you can connect. You can obtain these as follows:

     API Key

     To connect with IBM Cloud Object Storage, you need an API Key. You can obtain this as follows:

     1. Log in to your IBM Cloud account.
     2. Navigate to the Platform API Keys page.
     3. On the middle-right corner click "Create an IBM Cloud API Key" to create a new API Key.
     4. In the pop-up window, specify the API Key name and click "Create". Note the API Key as you can never access it again from the dashboard.

     Cloud Object Storage CRN

     If you have multiple accounts, you will need to specify the CloudObjectStorageCRN explicitly. To find the appropriate value, you can:

     • Query the Services view. This will list your IBM Cloud Object Storage instances along with the CRN for each.
     • Locate the CRN directly in IBM Cloud. To do so, navigate to your IBM Cloud Dashboard. In the Resource List, Under Storage, select your Cloud Object Storage resource to get its CRN.

     Connecting to Data

     You can now set the following to connect to data:

     • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
     • ApiKey: Set this to your API key which was noted during setup.
     • CloudObjectStorageCRN (Optional): Set this to the cloud object storage CRN you want to work with. While the connector attempts to retrieve this automatically, specifying this explicitly is recommended if you have more than Cloud Object Storage account.

     When you connect, the connector completes the OAuth process.

     1. Extracts the access token and authenticates requests.
     2. Saves OAuth values in OAuthSettingsLocation to be persisted across connections.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the IBM Cloud Object Storage JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.ibmcloudobjectstorage.jar

     Fill in the connection properties and copy the connection string to the clipboard.

     When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

     A typical JDBC URL is below:

     jdbc:ibmcloudobjectstorage:ApiKey=myApiKey;CloudObjectStorageCRN=MyInstanceCRN;Region=myRegion;OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;
   • Username: Enter the username.
   • Password: Enter the password.
4. In the Security section, select the allowed user roles.

Create Real-Time IBM Cloud Object Storage Reports

You can now create reports and analyses based on real-time IBM Cloud Object Storage data. Follow the steps below to use the standard report wizard to create an interactive report that reflects any changes to IBM Cloud Object Storage data.

1. On the global header, click New -> Data Model.
2. On the Diagram tab, select SQL query in the menu.
3. Enter a name for the query and in the Data Source menu select the IBM Cloud Object Storage JDBC data source you created.
4. Select standard SQL and enter a query like the following: SELECT Key, Etag FROM Objects WHERE Bucket = 'someBucket'
5. Click View Data to generate the sample data to be used as you build your report.
6. Select the number of rows to include in the sample data, click View, and then click Save As Sample Data.
7. Click Create Report -> Use Data Model.
8. Select Guide Me and on the Select Layout page select the report objects you want to include. In this example we select Chart and Table.
9. Drop a numeric column like Etag onto the Drop Value Here box on the y-axis. Drop a dimension column like Key onto the Drop Label Here box on the x-axis.
10. Click Refresh to pick up any changes to the IBM Cloud Object Storage data.
