High availability with attached documents

You can attach documents to multiple objects, create a document library, and organize documents into folders. You can configure Tivoli®'s process automation engine attached documents feature for your high availability architecture.

To configure attached documents for high availability, ensure that a shared disk is available for all nodes of the application server and HTTP servers.

Depending on the operating system, the shared disk that is used to store attachments must be either mountable or accessible through Universal Naming Convention (UNC) paths from all HTTP server and WebSphere® Application Server nodes. The user who starts the HTTP server services must have read access to the attached documents shared directory. The user who starts the WebSphere Application Server services must have write access to the shared directory.

Failover of the shared disk must be detectable by the HTTP server and the application server to avoid the need to change the configuration. Service IP and common directory paths are suitable ways to achieve transparency.
