Progress DataDirect Cloud™

Progress DataDirect Cloud enables simple, fast connections to cloud and on-premise data regardless of source—SaaS apps, big data stores, or social networks—using a single standards-based ODBC or JDBC driver, or OData enabled application. For example, an organization might want to use a reporting application to predict travel budgets by analyzing travel data stored in the cloud. DataDirect Cloud can provide connectivity with simple configuration instead of extensive coding. In addition, when you install the DataDirect Cloud On-Premise Connector on a machine behind your firewall, you can connect to on-premise data sources using DataDirect Cloud, without opening ports or otherwise configuring the fire wall. The On-Premise Connector establishes a secure connection back to DataDirect Cloud when needed to provide access to the on-premise data stores.

DataDirect Cloud– January 23, 2016

Resolved Issues

Google Analytics
  • B26016. Connections to view names that include forward slashes now succeed.
  • B24859. Queries against the CUBE and CUBEFIELD tables now execute successfully.
Oracle Service Cloud
  • B25911. When executing queries against large tables, a "poor performing query" error was returned.
Microsoft Dynamics CRM
  • B30550. Connections could sometimes return "an error occurred when verifying security for the message". 

Known Issues

Even with exhaustive testing, not all issues can be immediately resolved. The following issues have been noted:

All Data Sources
  • It is recommended that Login Timeout not be disabled (set to 0) for a Data Source.
  • Using setByte to set parameter values fails when the data source does not support the TINYINT SQL type. Use setShort or setInt to set the parameter value instead of setByte.
On-Premise Connector
  • Uninstalling and re-installing the On-Premise Connector causes the Connector Id of the On-Premise Connector to change. Any DataDirect Cloud data sources using the old Connector Id must be updated to use the new Connector Id. Installing to a new directory allows both the old and new On-Premise Connector to exist side-by-side. However, you must update the Connector Id option in previously-defined DataDirect Cloud data sources to point to the new On-Premise Connector.

    In addition, you must update Connector Id wherever it was used, such as the definitions of Group Connectors and Authorized Users.

  • Changing the name used to register an On-Premise Connector using an older On-Premise Connector Configuration Tool may cause the Connector to fail to register itself with D2C and cause 504 Gateway timeout errors to be returned. Installing the latest On-Premise Connector may resolve this issue.
Google Analytics
  • Once a Google Analytics OAuth profile is created for a specific Google account, changing the Google Account associated with the profile results in "the configuration options used to open the database do not match the options used to create the database" error being returned for any existing data sources.

  • In this release, creating a Google Analytics OAuth profile with the Data Source Management API is not supported.
OData
  • $expand only supports one level deep.

    For example, with the entity hierarchy:
    Customers
    |-- Orders
    | |-- OrderItems
    |-- Contacts


    The following queries are supported:
    Customers?$expand=Orders
    Customers?$expand=Contacts
    Customers?$expand=Orders,Contacts


    However, this query is not supported:
    Customers?$expand=Orders,OrderItems

    OrderItems is a second level entity with respect to Customers. To query Orders andOrderItems, the query must be rooted at Orders. For example:
    Orders?$expand=OrderItems
    Orders(id)?$expand=OrderItems


  • When manually editing the ODataSchemaMap value, the table names and column names specified in the value are case-sensitive. The case of the table and column names must match the case of the tables and column names reported by the data source.
    Note: It is highly recommended that you use the OData Schema Editor to generate the value for the ODataSchemaMap data source option. The Schema Editor takes care of table and column name casing and other syntactic details.
  • When using the substring function on properties that map to a CHAR column in the data source, it is data source dependent as to whether the substring function treats the trailing spaces as significant. When going against Oracle, the trailing spaces are preserved. When going against other data sources, the trailing spaces are discarded.
  • The $expand clause is not supported with OpenEdge data sources.
  • The day scalar function is not working when specified in a $filter clause when querying a DB2 data source.
Oracle Service Cloud
  • When you create a custom object, your Oracle Service Cloud administrator must enable all four columns of the Object Fields tab of the Object Designer, or you cannot query against the custom objects.
  • The initial connection when the relational map is created can take some time. It is even possible to receive an error "504: Gateway Timeout". When this happens, DataDirect Cloud continues to build the map in the background such that subsequent connection attempts are successful and have full access to the relational map.
Microsoft Dynamics CRM
  • Testing has shown the following two errors from Microsoft Dynamics CRM Online when executing queries against the ImportData and TeamTemplate tables:
    • Attribute errortype on Entity ImportData is of type picklist but has Child Attributes Count 0
    • Attribute issystem on Entity TeamTemplate is of type bit but has Child Attributes Count 0
    Note: We have filed a case with Microsoft and are waiting to hear back about the cause of the issue.

  • The initial on-premise connection when the relational map is created can take some time. It is even possible to receive an error "504: Gateway Timeout". When this happens, DataDirect Cloud continues to build the map in the background such that subsequent connection attempts are successful and have full access to the relational map.
OpenEdge 10.2b
  • Setting the MaxPooledStatements data source option in an OpenEdge data store to a value other than zero can cause statement not prepared errors to be returned in some situations.
SugarCRM
  • Data source connections by default now use Export Mode to communicate with the Sugar CRM server, providing increased performance when querying large sets of data. 

    Bulk export mode causes NULL values for currency columns to be returned as the value 0. Because of this, there is no way to differentiate between a NULL value and 0, when operating in export mode. This can be a problem when using currency columns in the SQL statements, because DataDirect Cloud must satisfy some filter conditions on queries, such as with operations like =, <>, >, >=, <, <=, IS NULL and IS NOT NULL.  For example, suppose a currency column in a table in SugarCRM has 3 null values and 5 values that are 0. When a query is executed to return all NULL values (SELECT * FROM <table> WHERE <>currency column> IS NULL), then 3 rows are returned. However, if a query is executed to return all rows where the column performs an arithmetic operation (SELECT * FROM <table> WHERE <currency column> + 1 = 1), then all 8 records are returned because the 3 NULL values are seen as 0.

DataDirect Cloud JDBC Drivers
  • The JDBC 32-bit silent installation fails on Windows 10. Use the standard installation, instead.
  • See the file d2cjdbcreadme.txt for the latest notes when accessing DataDirect Cloud through the DataDirect Cloud JDBC drivers. These files are located in the installation directory for the JDBC drivers.
DataDirect Cloud ODBC Drivers
  • See the file d2codbcreadme.txt for the latest notes when accessing DataDirect Cloud through the DataDirect Cloud ODBC drivers. These files are located in the installation directory for the ODBC drivers.
