Enabling strict virtualization mode in Data Virtualization

Data Virtualization Admins can determine the virtualization mode of the service.

About this task

The virtualization mode determines whether to enforce use of business terms in virtual table and column names. Use the strict virtualization mode if you want virtual objects to map to existing business terms only.

In this virtualization mode, users can virtualize only assets that have been added to a catalog by using a data source connection and that have a business term assigned at the asset level and to at least one column. The same connection must be added as a data source to Data Virtualization. Use one of the following options to catalog data source assets and assign business terms:

Add data assets from the data source and assign business terms manually.
Import and enrich data assets with information and business terms that help users to understand the meaning of the data, assess its quality, and decide how to work with it. For more information about metadata import, see Importing metadata from a project (IBM Knowledge Catalog). For more information about metadata enrichment, see Managing metadata enrichment (IBM Knowledge Catalog).

When you disable the strict virtualization mode, you set Data Virtualization to the default virtualization mode. In the default virtualization mode, you can virtualize any table from the supported data sources.

Required role: To complete this task, you must have the Data Virtualization Admin role.

Procedure

To enable the strict virtualization mode, follow these steps.

Log in to IBM Cloud Pak for Data.
You must have the Cloud Pak for Data data steward role and the Data Virtualization Admin role. Data Virtualization Stewards can see the configured virtualization mode only.
To check the status of the strict virtualization mode, enter the following GET request on your browser.
```
https://${CPD_URL}/icp4data-databases/dv/${DV_NAMESPACE}/dvapiserver/v1/security/strict/status
```

To enable the strict virtualization mode, enter the following GET request on your browser.

https://${CPD_URL}/icp4data-databases/dv/${DV_NAMESPACE}/dvapiserver/v1/security/strict/on

Replace the following values.

What to do next

Before virtualizing data in strict virtualization mode, delete objects that you virtualized before you enabled strict virtualization mode.
