These release notes provide enhancements, changed behavior, and resolved issues. When applicable, a component-specific version number is provided for the On-Premises Connector, ODBC driver, or JDBC driver.
The product version number can be obtained from the Hybrid Data Pipeline Web UI by selecting About from the help dropdown.
The On-Premises Connector version number can be obtained by opening the On-Premises Connector Configuration Tool and clicking the Version tab.
The JDBC driver version number can be obtained (1) by calling the DatabaseMetaData.getDriverVersion() method or (2) by executing the following command from the driver installation directory:
java -cp ddhybrid.jar com.ddtek.jdbc.ddhybrid.DDHybridDriver.
For the ODBC driver, see Driver version string for details on obtaining the driver version number.
Note: For the latest data source and platform support information, refer to the Product Compatibility Guide.
Hybrid Data Pipeline supports throttling the number of simultaneous OData queries a user may have running against a Hybrid Data Pipeline server at one time. OData query throttling for users may be configured with the ODataMaxConcurrentRequests and ODataMaxWaitingRequests limits. The ODataMaxConcurrentRequests limit sets the maximum number of simultaneous OData requests allowed per user, while the ODataMaxWaitingRequests limit sets the maximum number of waiting OData requests allowed per user. See Throttling in the user's guide for details.
Support for environment variables to specify server and system database credentials during the installation process has been added. The use of environment variables allows you to perform a more secure silent installation, compared to a standard silent installation where credential information must be specified in plain text in the silent installation response file. See Silent installation process in the user's guide for details.
When installing the Hybrid Data Pipeline server using SQL Server as the system database, the use of special characters in admin or user account credentials caused the installation to fail with the error Error in createSchema at Line 266.
NOTE: While installation no longer fails when special characters are used in system database account credentials, the installer cannot currently validate the necessary database schema objects when any of the following special characters are used in either database user ID or password values: space ( ), quotation mark ("), number sign (#), dollar sign ($), and apostrophe ('). Therefore, in a standard installation where these characters are used in database credentials, database validation must be skipped to proceed with the installation. Similarly, when performing a silent installation in this case, the SKIP_DATABASE_VALIDATION property should be set to true. Note that when skipping database validation in this scenario, the server should install successfully and work with the specified system database.
The specification of system database admin and user passwords in plain text in the response file as part of the silent installation process raised security concerns. Support for environment variables to specify server and system database credentials during the installation process has been added. See Silent installation process in the user's guide for details.
When the HAProxy load balancer was configured with the setting x-content-type-options:nosniff, Firefox, Chrome, and Microsoft Edge browsers rendered the Web UI as text instead of HTML.
