Vercel Reporting in OBIEE with the Vercel JDBC Driver

The CData JDBC Driver for Vercel is a standard database driver that can integrate real-time access to Vercel 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 Vercel 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.

set PRE_CLASSPATH=your-installation-directory\lib\cdata.jdbc.api.jar;%PRE_CLASSPATH%

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

Create a JDBC Data Source for Vercel

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.api.APIDriver.
   • Connection String: Enter the JDBC URL.

     Using API Key Authentication

     Vercel uses Bearer token authentication. You can use either a personal access token or an OAuth access token as the API key.

     To obtain a personal access token:

     1. Log into your Vercel account at https://vercel.com/
     2. Navigate to Account Settings > Tokens.
     3. Click Create Token, enter a name and expiration, and click Create.
     4. Copy the generated token (it will only be shown once).

     After obtaining your token, set the following connection properties:

     • AuthScheme: Set this to APIKey.
     • APIKey: Set this to your Vercel personal access token or OAuth access token.

     Example Connection String

     Profile=C:\profiles\Vercel.apip;AuthScheme=APIKey;APIKey=your_access_token;
     

     Working with Teams

     Many Vercel resources are scoped to a team. To scope all requests to a specific team, set the TeamId connection property to your team's ID. You can find your team ID by querying the Teams table or from the Vercel dashboard. Alternatively, you can specify TeamId in your SQL queries using the WHERE clause where supported.

     Connecting to Vercel

     Once the authentication is configured, you can connect to Vercel and query data from any of the available tables such as Projects, Deployments, Teams, and Domains.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.api.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:api:Profile=C:\profiles\Vercel.apip;AuthScheme=APIKey;APIKey=your_access_token;

   • Username: Enter the username.
   • Password: Enter the password.

Create Real-Time Vercel Reports

You can now create reports and analyses based on real-time Vercel data. Follow the steps below to use the standard report wizard to create an interactive report that reflects any changes to Vercel 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 Vercel JDBC data source you created.
4. Select standard SQL and enter a query like the following:

   SELECT , FROM User WHERE = ''

   👁 The SQL query to be used to create the data set for the report's data model. (Salesforce is shown.)
   
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 onto the Drop Value Here box on the y-axis. Drop a dimension column like onto the Drop Label Here box on the x-axis. 👁 The dimensions and measures for a chart. (Salesforce is shown.)
   
10. Click Refresh to pick up any changes to the Vercel data. 👁 An interactive, refresh-on-demand report. (Salesforce is shown.)
