Enhancements and resolved issues are provided according to product version number. The product version number can be obtained from the Hybrid Data Pipeline Web UI by selecting About from the help dropdown. When applicable, a component-specific version number is provided for the On-Premises Connector or a driver. Version numbers for these components are not available through the Web UI. The On-Premises Connector version number can be obtained by opening the On-Premises Connector Configuration Tool and clicking the Version tab. The version number for the JDBC driver 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.
OData query throttling for users
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.
Environment variables support for silent installation
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.
Issue HDP-4853 Installation failed when special characters were used in system database credentials
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.
Issue HDP-4854 Silent installation process required the specification of system database admin and user passwords in clear text in the response file
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.
Issue HDP-4859 Firefox, Chrome, and Microsoft Edge browsers not rendering Web UI correctly for load balancer installation
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.
Hybrid Data Pipeline has added support for a subset of the functionality defined by the OData Version 4 extension for data aggregation. Aggregation functionality is extended with the $apply query parameter. See Aggregation support in the user's guide for details.
Windows Server 2019
The Hybrid Data Pipeline On-Premises Connector, ODBC driver, and JDBC driver have added support for Windows Server 2019. (On-Premises Connector version 18.104.22.168, ODBC driver 22.214.171.124, JDBC driver 126.96.36.199)
Issue HDP-4478 Unable to connect using TNS connection option for Oracle
The Hybrid Data Pipeline server required the specification of the Server Name parameter, even though Server Name is not required for a TNS connection. In addition, when Server Name was specified, the server returned an inaccurate error message.
Issue HDP-4757 Cannot retrieve data from SQL Server table (On-Premises Connector version 188.8.131.52)
Sometimes when trying to execute SELECT * FROM table against an on-premise SQL Server database using the On-Premises Connector, the ODBC driver returned the error [HY000] [DataDirect][ODBC Hybrid driver][SQLServer]Unexpected content at the end of chunk.
Issue HDP-4574 HTTP error 404 while renaming the connector label (On-Premises Connector version 184.108.40.206)
When the name of the On-Premises Connector host machine was in all uppercase at the time of the installation of the On-Premises Connector, the Connector Label field in the On-Premises Configuration Tool did not populate with the hostname as expected. Then, when attempting to update the Connector Label field with the correct hostname, the On-Premises Configuration Tool returned Error setting connector label for user Request returned Status:404 Message.
Issue HDP-4704 Error while accessing link tables in MS Access application using Hybrid Data Pipeline data source (ODBC driver 220.127.116.11)
When using the Hybrid Data Pipeline ODBC driver to connect to a data source created with a third party JDBC driver, the following error was returned: ODBC--call failed. [DataDirect][ODBC Hybrid driver]Numeric value out of range. Error in column 16. (#0). This error was returned because the third party driver diverged from the JDBC specification when describing the data type of CHAR_OCTET_LENGTH for DatabaseMetaData.getColumns(). The ODBC driver has been modified to work with the third party JDBC driver despite this divergence from the JDBC specification.
SQL statement auditing
Hybrid Data Pipeline has added a SQL statement auditing feature. When SQL statement auditing is enabled, the connectivity service records SQL statements and related metrics in the SQLAudit table on the Hybrid Data Pipeline system database (also referred to as the account database). This information can then be queried directly by administrators. See SQL statement auditing in the user's guide for details.
The Hybrid Data Pipeline server and On-Premises Connector have been upgraded to install and use Tomcat 9.0.37. (On-Premises Connector version 18.104.22.168)
Issue HDP-4534 Unable to connect to Google Analytics data source
When connecting to Google Analytics data source using an OAuth profile created in a previous version of Hybrid Data Pipeline, the following error was returned: There is a problem connecting to the data source. Error getting data source. System not available, try again later.
Issue HDP-4490 ODataApplicationException returned when filtering on BIT/BOOLEAN field
When exposing a Microsoft SQL Server table via OData Version 4 and filtering on a BIT/BOOLEAN field, Hybrid Data Pipeline returned the ODataApplicationException An expression of non-boolean type specified in a context where a condition is expected, near ')'.
Issue HDP-4480 Shutdown script not working
With some shell configurations, the Hybrid Data Pipeline shutdown script stop.sh was not shutting down Hybrid Data Pipeline server processes.
Issue HDP-4465 Parenthesis in OData query not honored
When translating an OData Version 4 query to a SQL query, Hybrid Data Pipeline did not honor the parenthesis in the OData query. This caused the reordering of the operator precedence, and lead to incorrect results. The parenthesis in OData queries is now reproduced in SQL queries to maintain operator precedence.
Issue HDP-4464 Intermittent error "origin=driver message=PAYLOAD_TYPE_BINARY != opcode, was 10" (On-Premises Connector version 22.214.171.124)
When connecting to an on-premise data source using the On-Premises Connector, the error origin=driver message=PAYLOAD_TYPE_BINARY != opcode, was 10 was returned. The On-Premises Connector now correctly handles pongs sent from load balancers according to WebSocket protocol.
Entity case conversion feature
The Hybrid Data Pipeline has been enhanced to support case conversions for entity types, entity sets, and properties. The owner of a data source can now change the entity type, entity set, and property names to all uppercase or all lowercase on the OData tab in the Web UI or using the Hybrid Data Pipeline Management API.
Web UI data source sharing feature
The Web UI has been enhanced to support data source sharing. The owner of a data source can now share access to a data store with Hybrid Data Pipeline users and tenants through the Data Sources view in the Web UI.
Web UI IP address whitelist feature
The Web UI has been enhanced to fully support the IP address whitelist feature. Administrators can secure access to Hybrid Data Pipeline resources by implementing IP address whitelists through the Web UI. The Web UI can be used to create IP address whitelists at the system level, tenant level, user level, or some combination of these levels
Web UI navigation bar
The navigation bar can be expanded to show the names of the views supported in the Web UI. The icons in the navigation bar have been reordered and updated.
PostgreSQL OData Version 4 stored functions
Hybrid Data Pipeline supports exposing stored functions for OData Version 4 connectivity to PostgreSQL data sources. When configuring a PostgreSQL data source, the OData schema map can be configured to expose stored functions.
JDBC and ODBC throttling
A new throttling limit has been introduced in the System Limits view. The XdbcMaxResponse limit can be used to set the approximate maximum size of JDBC and ODBC HTTP result data.
ODBC driver branded installation
The ODBC driver installation program has been enhanced to support branded installations for OEM customers (available in the ODBC driver installer on November 18, 2019). The branded driver can then be distributed with OEM customer client applications. For the Hybrid Data Pipeline ODBC driver distribution guide, visit the Progress DataDirect Product Books page on the Progress PartnerLink website (login required).
