Overview

z/OS Unix Systems Services, previously known as OpenEdition/MVS is a UNIX operating environment that is an integral part of the z/OS system. Many corporations looking to leverage the strengths of the z/OS world are also looking to take advantage of USS by using applications that operate under USS, such as using the mainframe as a WEB server, Websphere, or Lotus Domino. The z/OS UNIX files reside on MVS storage, and as a result the z/OS storage management team is being tasked with the responsibility for backups and restores. Traditional z/OS storage management products can backup an entire USS file system, but are unable to offer file level support. In today's corporate environment with a greater emphasis on leaner and fewer operations staff, greater efficiency, 24 x 7 availability, and the growing E-commerce marketspace, that's not good enough. Why restore an entire volume when you only need a single file within the dataset? Thus the best way to offer the best class of service and reliably provide file level backup and restore support as an Unix Systems Services application, such as FDR/Upstream

The HFS and z/FS file systems offers a number of file system features not found in other UNIX systems including external links (references to true MVS files), auditing flags and HFS extended attributes. For backup and restores, the HFS file system includes such UNIX features as long file names, case sensitivity, UNIX type security, and symbolic links. The best way to back these up is via a true USS application. That's where FDR/Upstream for Unix Systems Services support comes in! It supports the UNIX Systems Services features: External Links, Symbolic Links, Auditing flags HFS Extended Attributes, Unix owners and permissions, and case sensitivity. And because FDR/Upstream is also an z/OS application, you can save time and money on your z/OS storage management team for training issues.

FDR/Upstream was designed as a complete storage management solution for corporate data distributed across a heterogeneous network. The facilities of FDR/UPSTREAM provide companies with completely automated operations for backup/restores, file transfers, and storage management operations. FDR/UPSTREAM offers several unique data reduction techniques to minimize the amount of data to be transmitted, leverages the advanced services and dependability of the MVS server, while offering low resource and system utilization. By using the automation systems of the FDR/UPSTREAM MVS server, storage managers can have the highest degree of flexibility and reliability in backup management, while offering unparalleled features! And now with Upstream/Unix Systems Services support, they can improve efficiency and save time and resources.

The FDR/UPSTREAM UNIX Systems Services process can be initiated manually or automatically with your existing MVS job scheduler. By submitting MVS "batch jobs", the Upstream process can wait until the completion of the request. JCL condition code checking can then take place providing automated exception handling. The z/OS tape management system controls the retention period of the backups and the z/OS security system controls access to the system. Restores can be performed and controlled from either a TSO ISPF panel or JAVA interface. The JAVA interface provides an easy to use, graphical user interface that fully utilizes the FDR/UPSTREAM storage management functions especially for restores, and can be used from a PC or X Terminal.

FDR/UPSTREAM for Unix Systems Services for z/OS is similar to the other UNIX client versions of FDR/UPSTREAM. It supports the following UNIX Systems Services file system features:

  • External Links
  • Symbolic and Hard Links
  • Auditing flags
  • HFS and z/FS Extended Attributes
  • Unix owners and permissions
  • ACL attributes
  • Case sensitivity
  • FIFOs 

The FDR/UPSTREAM Unix Systems Services product has similar operational characteristics as the other UNIX versions of the FDR/UPSTREAM product.

FDR/UPSTREAM Unix Systems Services can be licensed separately from other FDR/UPSTREAM components, or can be licensed as an option to FDR/UPSTREAM or FDR/UPSTREAM/SOS.

FDR/UPSTREAM UNIX Systems Services requires z/OS V1R4 or above.
