Oracle Integration with SharePoint - Features & Benefits


  • Very easy to setup in a few minutes: Create a new SharePoint list, click "Connect to external data source" in the list settings, select the data provider, enter connection settings and data query as shown below ... that's it.
  • No changes in the Oracle data source required: No programming, no additional tools.
  • Connected list data always up-to-date: The connected Oracle data query updates the SharePoint list automatically in background (via SharePoint Timer Job), or alternatively, on-demand (Action Menu / Ribbon Button, URL, via workflow, API).
  • One-way and optional two-way connection: You can write-back the changes made in the SharePoint list to the external data source automatically with full CRUD (Create / Update / Delete) functionality. The SharePoint list can act as a full-featured front-end for external systems.
  • Well-known BCS "external list" issues and limitations are completely solved: ALL list features are to you. Views, sorting and grouping, filters, calculated fields, search, managed metadata. Lookups, additional columns and attachments can be created as normal. All kind of lists can be used, e.g. contacts, tasks, calendar, or custom lists. You can take external data offline via Outlook.
  • Workflows and notifications on external data change: List workflows and change notifications per RSS or email can be used to take business actions in SharePoint, when external Oracle data records are changed.
  • Application logging, reporting, and notifications: A SharePoint list is used to store settings and log information. SharePoint item versioning and workflows can be used to manage reporting and notifications. Direct notification per email in case of errors is supported as well.
  • Highest Security, best performance, easy to maintain: SharePoint Secure Store can be used to store security relevant configuration information safely in one central place. Users are working with the SharePoint lists as an external data cache with highest security and performance. Large data sources can be synchronized.
  • 100+ more external systems supported: Layer2 Data Providers included (e.g. for external SharePoint or Office 365, Exchange, Dynamics ERP/CRM, OData, XML/RSS, SOAP), vendor specific data providers can be used (e.g. SQL Server Oracle, MySQL etc.), 3rd party data providers also supported, e.g. for custom ERP/CRM, Facebook or Twitter. See here for supported systems and applications.

  • You will need to have the Oracle Data Access Components and Tools - .NET and Windows (ODAC) installed on each machine in the farm that is running BDLC. You can find the component on the Oracle software download page.
  • Use the 64-bit version of the driver.
  • You can use a connection string like this to connect:
    Data Source=myOracleDatabase; User Id=myUser; Password=myPassword;

    You will find more information about Oracle connection strings here.
  • You can make use of all SQL queries the Oracle data provider supports. You can also use stored procedures that returns records, exec myStoredProcedure().
  • You can map your list columns to specific external data source fields in the Layer2 Business Data List Connector. Please take care about data types (simple type conversions are supported).
  • Primary keys should be automatically set, if they exist in the Oracle table.
  • Write-back is supported. You can use this to write changes in SharePoint back to Oracle. Please take care to set appropriate primary keys.
  • No programming required for setup a connection and sync.
  • No need to open your local network for access from outside. No 3rd party involved.

SharePoint Integration with Oracle - Examples, Known Issues, and Workarounds

There are following known issues and workarounds with Oracle integration:


  • The Layer2 Business Data List Connector also supports the use of the ODBC and OleDb Oracle drivers provided in the ODAC, as well as the Microsoft Oracle provider installed with Windows.
  • In case of integrated authentication (trusted connection) please make sure that the current user and any related service accounts have appropriate database access rights.
  • In case of issues with the Oracle TNS, please google the specific error messages for solutions. Make sure that both the current user and any related service accounts have access to the TNS.
  • Blobs, images, CLOBs, or other binary fields are not supported at this time.
  • If using write-back, your query must be updatable (most joins are not). You will also need write access rights for this.
