SAP ASE OCF Connector: Overview

The OCF connector for SAP ASE (Sybase ASE) was developed by Alation and is available as a Zip file that can be uploaded and installed in the Alation application. The connector is compiled together with the required database driver, so no additional effort is needed to procure and install the driver.

To download the Sybase ASE OCF connector package, go to the Alation Connector Hub available from the Customer Portal. Go to Customer Portal > Connectors > Alation Connector Hub. Only Alation users with access to the Customer Portal can access the Alation Connector Hub. If you don’t have access to the Customer Portal, contact Alation Support.

This connector should be used to catalog SAP ASE as a data source on Alation on-prem and Alation Cloud Service instances. It extracts and catalogs such database objects as schema, tables, columns, views, primary key, foreign key, functions, and function definitions. 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, curate the corresponding catalog pages, create documentation about the data source, and exchange information about it.

Team

The following administrators are required to install this connector:

  • Alation administrator:

    • Ensures that Alation Connector Manager is installed and running or installs it.

    • Installs the connector.

    • Creates and configures the SAP ASE data source in the catalog.

    • Performs initial extraction and prepares the data source for Alation users.

  • SAP ASE administrator:

    • Creates a service account.

    • Provides the JDBC URI to access metadata

    • Provides access to databases to extract metadata.

    • Assists with setting up Query Log Ingestion.
