How to: |
In some cases, a Visual Discovery AE project can be dynamically switched to point to different data sources. This is almost always used with standard published projects where the data is loaded into the project, each session, from the original source text file.
Note: This is only recommended when data load times are so extensive that the embedded option and hard-coded re-routes are the only methods available. Passing live WebFOCUS procedures is the recommended approach.
In another scenario, guided Ad hoc generated VISDISAE data sets can be saved at runtime, to specific directories, based on the user name and timestamp. Using this information, Visual Discovery AE links can be created with parameters that define the path to find the newly generated data set. It is also used to redirect users to Visual Discovery projects with their customized data set.
Note:
For more information on scalability, see the WebFOCUS Visual Discovery Analyst Edition Implementation Guide.
For example, in the visdisproj directory, create a folder called &&COUNTRY.
For more information, see Designing a Project Using WebFOCUS Visual Discovery Workbench AE and Publishing Visual Discovery AE Projects to a Larger (Web-Based) Audience.
Note: When publishing the project, ensure that the Embed Data option is not selected in the Publish Dashboard dialog box. This ensures that data can be dynamically loaded from different data sets.
Update the generated link provided by WebFOCUS Visual Discovery Workbench AE.
The following is the format of the query string parameter:
visParms=<Original_Base_Folder_Name>:<Actual_Folder_Name>
For example:
http://localhost/ADV/Projects/Demo/carvisdisae.aspx?visParms=COUNTRY:FRANCE
http://localhost/ADV/Projects/Demo/carvisdisae.aspx?visParms=COUNTRY:ENGLAND
