Features Removed in Virtual DataPort 7.0¶
This section lists the features that are no longer available in Denodo 7.0.
- I18n Settings
- VQL Syntax
- JDBC Data Source Dialog: Choose Automatically
- ODBC Data Sources
- JDBC/ODBC Source Configuration Properties
- XMLA Connectors for SAP
- Comparison of Strings: Case Sensitive
- Published Web Services: “with LDAP” Authentication
- Export Script
- Denodo JDBC Driver
- Denodo ODBC Driver
I18n Settings of the Cache Engine¶
com.denodo.vdb.cache.i18nCode has been removed. Even if it is present in the VDBConfiguration.properties file, its value is ignored. Instead, Denodo use the “Default i18n” of the Server (configured in the “Server configuration”) to read/write values from/to the cache that need an i18n.
Starting with Denodo 7.0, when you change the i18n of the Denodo server, Denodo invalidates the cache of the views that have one or more fields of type timestamptz and/or date (deprecated type).
We are referring to when you do it from the administration tool or when you execute this statement:
SET 'com.denodo.vdb.misc.I18nParametersManager.i18nDefault'='<new i18n map>';
Databases and Cache Do not Have I18N¶
The Denodo databases and cache no longer can have a different i18n setting. Now all of them have the same i18n setting.
Using single quotes to surround identifiers is no longer valid. Although deprecated in Denodo 5.0, prior versions still allow it.
For example, this query is no longer valid.
SELECT * FROM 'admin'.'iinc_sqls' WHERE 'iinc_sqls'.'summary' = 'Bandwidth increase';
When necessary, the identifiers have to be surrounded with double quotes. For example:
SELECT * FROM "admin"."iinc_sqls" WHERE "iinc_sqls"."summary" = 'Bandwidth increase';
JDBC Data Source Dialog: Choose Automatically¶
The check box Choose automatically of the JDBC and ODBC data sources has been removed.
ODBC Data Sources¶
The following ODBC adapters have been removed:
- Microsoft Excel. Instead, create an Excel data source.
- Microsoft SQL Server. Instead, create a JDBC data source with one of the adapters for SQL Server.
JDBC/ODBC Source Configuration Properties¶
The VDP server will no longer accept
minevidectabletime. We will continue supporting
minevictabletime, which is
the right way of spelling it.
The source configuration properties
delegateorderbycollation are no longer supported.
The server supported them so VQL files from versions prior to 6.0 could be imported without errors but in this version
the support for these properties will be removed.
XMLA Connectors for SAP¶
The XMLA adapters for SAP (i.e. “SAP BW 3.x (XMLA)” and “SAP BI 7.x (XMLA)”) have been removed. Use the adapter “SAP BI 7.x (BAPI)” instead.
Comparison of Strings: Case Sensitive¶
Starting with Denodo 5.0, the comparison of strings on Virtual DataPort is case-sensitive. In previous versions it was possible to go back to the previous behavior (case-insensitive comparisons). In Denodo 7.0 it is no longer possible.
Performing case-insensitive comparison has a significant computational cost when dealing with huge volumes of data.
Published Web Services: “with LDAP” Authentication¶
The following authentication methods of published web services have been removed:
- For REST web services, “HTTP Basic with LDAP”.
- For SOAP web services, “HTTP Basic with LDAP” and “WSS Basic with LDAP”.
When migrating to Denodo 7.0, web services with these authentication methods must be edited using the Administration Tool before exporting the VQL, assigning any of the authentication methods supported in Denodo 7.0. In other case, the VQL generated will not be valid to import in 7.0.
caseSensitive of the export script have been removed.
Denodo JDBC Driver¶
The basic “flavor” of the JDBC driver has been removed. From now on, there is only one “flavor” of the driver:
Internal Pool of Connections¶
The Denodo JDBC driver was capable of creating its own pool of
connections to Virtual DataPort. This feature has been removed. The implication is that the parameters
maxIdle are no longer be valid.
Applications that need to create a pool of connections to Virtual DataPort should use their own library to do it.
Kerberos Constrained Delegation¶
requestCredDeleg is no longer supported. Instead, use the property
userGSSCredential to pass the impersonated credential to the driver.
Denodo ODBC Driver¶
com.denodo.vdb.vdbinterface.server.odbc.forceBinaryTypes (described in the documentation of Denodo 6.0, section Increasing the Performance of the Denodo ODBC Driver) has been removed.
The speed improvement provided by this option was insignificant and after enabling it, ODBC clients only could use the Denodo ODBC driver.
The “exe” files of <DENODO_HOME>/bin have been removed (i.e. vqlserver_startup.exe, denodo_platform.exe, etc.). This prevents confusion among newer users that did not know if there is any difference between both (there is not). Use the equivalent .bat scripts (vqlserver_startup.bat, denodo_platform.bat, etc.) The .bat scripts provide the same functionality as the exe.
