Use the CData JDBC Driver for IBM Cloud Object Storage in MicroStrategy

MicroStrategy is an analytics and mobility platform that enables data-driven innovation. When you pair MicroStrategy with the CData JDBC Driver for IBM Cloud Object Storage, you gain database-like access to live IBM Cloud Object Storage data from MicroStrategy, expanding your reporting and analytics capabilities. In this article, we walk through creating a database instance for IBM Cloud Object Storage in MicroStrategy Developer and create a Warehouse Catalog for the IBM Cloud Object Storage data.

The CData JDBC Driver offers unmatched performance for interacting with live IBM Cloud Object Storage data in MicroStrategy due to optimized data processing built into the driver. When you issue complex SQL queries from MicroStrategy to IBM Cloud Object Storage, the driver pushes supported SQL operations, like filters and aggregations, directly to IBM Cloud Object Storage and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can visualize and analyze IBM Cloud Object Storage data using native MicroStrategy data types.

Connect to IBM Cloud Object Storage in MicroStrategy Developer

You can connect to IBM Cloud Object Storage in MicroStrategy Developer by adding a database instance based on the CData JDBC Driver for IBM Cloud Object Storage.^* Before you begin, you will need to install the JDBC Driver for IBM Cloud Object Storage on the machine hosting the MicroStrategy Intelligence Server that your instance of MicroStrategy Developer is connected to.

1. Open MicroStrategy Developer and select a Project Source.
2. Navigate to Administration -> Configuration Managers -> Database Instances and right-click to add a new instance.
3. Name the instance, select Generic DBMS as the database connection type, and create a new database connection.
4. In the database connection wizard, name the connection and create a new Database Login name, setting the user and password for IBM Cloud Object Storage.
5. On the Advanced tab for the connection wizard, set the additional connection string parameters as follows.
   • Add the JDBC keyword to the connection string.
   • Set MSTR_JDBC_JAR_FOLDER to the path of the directory containing the JAR file for the JDBC driver. (C:\Program Files\CData JDBC Driver for IBM Cloud Object Storage\lib\ on Windows.)
   • Set DRIVER to cdata.jdbc.ibmcloudobjectstorage.IBMCloudObjectStorageDriver, the driver class.
   • Set URL to the JDBC URL for the IBM Cloud Object Storage driver, which contains the necessary connection properties.

     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.

   Typical additional connection string properties follow:

   JDBC;MSTR_JDBC_JAR_FOLDER=PATH\TO\JAR\;DRIVER=cdata.jdbc.ibmcloudobjectstorage.IBMCloudObjectStorageDriver;URL={jdbc:ibmcloudobjectstorage:ApiKey=myApiKey;CloudObjectStorageCRN=MyInstanceCRN;Region=myRegion;OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;};
6. Ensure that you have not selected an ODBC data source (this will trigger MicroStrategy to use the additional connection string parameters to build the database instance) and click OK.
7. Click OK to close the database instance wizard.
8. In the Project Source, right-click the project and open the Project configuration.
9. Navigate to Database Instances, select the newly created database instance, and click OK.
10. Close MicroStrategy Developer and restart the connected MicroStrategy Intelligence Server to complete the database instance creation.

With the database instance configured, you will now be able to connect to IBM Cloud Object Storage data from the Warehouse Catalog and Data Import.

Connect to IBM Cloud Object Storage Data from the Warehouse Catalog

Once you have created a database instance based on the JDBC Driver for IBM Cloud Object Storage, you can connect to data from the Warehouse Catalog.

1. Select your project and click Schema -> Warehouse Catalog.
2. In the Read Settings for the Catalog, click Settings and set the queries to retrieve the schema:
   • To retrieve the list of tables, use the following query: SELECT * FROM SYS_TABLES
   • To retrieve the list of columns for selected tables, use the following query: SELECT DISTINCT CatalogName NAME_SPACE, TableName TAB_NAME, ColumnName COL_NAME, DataTypeName DATA_TYPE, Length DATA_LEN, NumericPrecision DATA_PREC, NumericScale DATA_SCALE FROM SYS_TABLECOLUMNS WHERE TableName IN (#TABLE_LIST#) ORDER BY 1,2,3
3. Select tables to be used in the project.

Using the CData JDBC Driver for IBM Cloud Object Storage in MicroStrategy, you can easily create robust visualizations and reports on IBM Cloud Object Storage data.
