Adding and Removing Data Source Resources
You can add or remove data resources at any time. Adding resources requires introspection of the data source to obtain the metadata about the new resources.
When you remove resources from TDV, you are deleting the TDV metadata about the resource and not the actual resource. If you remove a resource that had dependencies, the dependent resource names in the Studio resource tree turn red, alerting you to resource problems.
To add or remove data source resources
1. Right-click the data source in the resource tree, and select Add/Remove Resources, or open the data source’s Configuration tab and click Add/Remove Resources. See Editing or Reviewing Configuration Information for a Data Source.
The Enter Password window opens if the password to access the data source was not saved when the data source was originally added to the server. For further details, see the descriptions for the Save Password and Pass-through sign-in fields under Adding Relational Data Sources.
2. If requested, supply the password that is required to access the data source, and click OK.
3. In the Add/Remove Resources window, do one of the following:
— To add a resource, select the corresponding check box.
— To remove a resource, clear the corresponding check box.
— To change the settings for adding new resources during reintrospection, check the Detect New Resources During Re-Introspection box. For details, see the section Setting Introspection Filters on a Resource.
4. Click Next to review the Introspection Report and if satisfied begin the introspection.
— This window can be dismissed at any time to continue running in the background. The re-introspection process also runs independently of the Studio session.
— Those resources that do not have a change in the metadata used by TDV contribute to the Skipped count.
— Use the Show pull-down filter to quickly show any errors or warnings.
— The introspection (re-introspection) status report can be exported as a text file.
