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.
2. On the Configuration tab, depending on your data source type, you can review and modify the following information:

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.
Owner
Domain to which the owner of the data source belongs, or the sign-in name of the user who created the data source.
Orig Creation Date
Date the data source was originally created.
Orig Owner
Name of the owner who originally created this data source.
Last Modified Date
Date when the resource was last edited.
Last Modified User
Name of the user who last edited the resource.
Lock
Owner of the lock on the resource, or Not Locked. TDV resources can be locked by a user to prevent concurrent and conflicting changes. See the Annotating a Resource.
Cluster Health Monitor Table
Displays the table used to monitor the health of an Active Cluster. It contains the heartbeat messages from all nodes. Its purpose is to help caching determine the health of other nodes in the cluster in case of a cluster split. Refer to the Active Cluster Guide for more information.
Refresh Capability Information
Use to refresh the capability information for this data source.
Case Sensitivity
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.
Trailing Spaces
Annotation
Area at the bottom of the panel that displays notes about the data source. Any user with Write permission can edit the annotation.
4. Save any changes.
5. If changes were made, perform a re-introspection.
