Editing or Reviewing Configuration Information for a Data Source
After a data source has been configured and introspected as a new physical data source, the configuration information can be reviewed by opening the data source in Studio. The tabs display details about the data source connection and other configuration information. The details differ depending on data source type (relational, web-based, file, and so on).
If you make changes, you need to save changes when you close the data source. You also need to reintrospect the data source to apply your changes. For more information, see Reintrospecting Data Sources.
To edit or review data source configuration details
| 1. | Right-click the data source name in the Studio resource tree and select Open. |

| 3. | Review or edit the following information on the Info tab: |
|
Field |
Description |
|
Name |
User-defined name given to the data source during introspection. |
|
Type |
Type of the resource, which is Data Source in this case. |

Domain to which the owner of the data source belongs, or the sign-in name of the user who created the data source. |
|

Refresh Capability Information |
Use to refresh the capability information for this data source. |
|
Reports whether the case sensitivity and trailing spaces settings do or do not match between TDV and the data source capability file. A mismatch does not necessarily reduce performance unless it results in a full-table scan performed locally by TDV. See the “Configuring Case and Space Settings” topic in the TDV Administration Guide. |
