Distributed Disk Services allows users to read and write files on UNC Disk Groups without requiring permission to the underlying file system. Access to these files is controlled using permissions. To ensure the best overall system performance, Distributed Disk Services should be deployed and configured according to the following best practices:
- Distributed Disk Services should not be configured for applications that utilize the OnBase Application Server.
- Distributed Disk Services should not be configured for applications that utilize the OnBase API Server.
- Distributed Disk Services should not be configured for the Unity Scheduler.
- Distributed Disk Services usage through the OnBase Client should be limited as much as possible. Users should be migrated to OnBase Core Services, including the Web or Unity Client.
Core Services feature a modern client-server architecture in contrast to the direct ODBC connection used by the older Client. Additional features such as Unity Forms can only be accessed using Core Services. Using the Web Client also allows usage with no local installation required. Beginning in OnBase Foundation 23.1, these best practices are enforced by changes to DDS access across the OnBase product suite. For more information, see Disk Group Access in Core Services.
