Overview¶
Alation Cloud Service Applies to Alation Cloud Service instances of Alation
Customer Managed Applies to customer-managed instances of Alation
The connector for TIBCO Data Virtualization (TDV) is available for download from the Connector Hub on the Alation Customer Portal. Follow instructions in this documentation to install or manage the connector.
TDV is a data virtualization software that combines data from multiple data sources and makes it available to users. Alation uses the TDV connector to catalog metadata from various data sources in TDV. Use this connector to catalog TDV as a data source on Alation on-premise and Cloud Service instances. It extracts and catalogs such database objects as schemas, tables, and columns. After the metadata is extracted, it is represented in the data catalog as a hierarchy of catalog pages under the parent data source. Alation users can leverage the full catalog functionality to search for and find the extracted metadata and curate the corresponding catalog pages.
Team¶
You may need the assistance of your database administrator to configure this data source.
TDV administrator:
Creates a service account for Alation.
Assigns permissions to anonymous users.
Provides the connection information and the JDBC URI.
Provides the authentication information and assists in configuring OAuth authentication.
Alation Server Admin:
Ensures that Alation Connector Manager is installed and running or installs it.
Installs the connector.
Creates and configures the TDV data source in the catalog.
Performs initial extraction and prepares the data source for Alation users.
