Application Scenarios

Written by Jochen Hager on . Posted in ACC Features

There are multiple real live application scenarios that can be supported by the ACC to enhance a given SAP archiving landscape or to facilitate specific transitory functions during a migration process.

Typical application scenarios:

  • Serving as a proxy during an archive migration by sending r/w calls to the target repository and sending read-only calls the source repository, while actively migrating in the background. This allows switching to the target repository on day one and guaranties a fully user transparent transition.
  • Supporting partial archive copies during company mergers and splits by functioning as a security gateway, restricting call for copies to selected documents and selected repositories only.
  • Forwarding (unchanged), securing (HTTPS) and/or signing (SAP SecKey) calls to a new target repository without changing the configuration or coding of the triggering application.
  • Supporting split storage setups, with a section of the archive in a cloud base reduced access location and another section in a high availability on premise location.

Features

Written by Jochen Hager on . Posted in ACC Features

The Archive Content Connector (ACC) is an HTTP Servlet that connects one SAP system to several SAP ArchiveLink content repositories. In a round robin schema, it attempts to handle a call by forwarding to real repositories, possibly manufactured by different vendors, in sequence. The first successful response is passed back to the caller (usually an SAP system).

Additional features include:

  • Restricting access to listed repositories only
  • Restricting/allowing read/write/delete access to repositories
  • Restricting access to only certain document ids (whitelisting)
  • Obscuring document content while verifying the existence of a document (placeholder display)
  • Forwarding calls to a specific archive system through URL rewrite (IP address, service name, port number)
  • Adding HTTPS security to the transmission
  • Adding/replacing SAP SecKey identification, including link expiration to unsecured calls with custom security certificate
