SAS/MDDB Server Administrator's Guide

Accessing MDDBs Remotely

Remote access of MDDBs is preferable to copying them if the MDDBs are frequently updated or your data center rules prohibit multiple copies of data. Depending on which method you use, you can specify read, write, and update access to your MDDBs from remote clients on a single-client or multiple-client basis.

Accessing MDDBs Via Remote Library Services

To access MDDBs via Remote Library Services (RLS), you establish a SAS/SHARE or SAS/CONNECT session and declare libraries on the remote hosts as shown in Transporting MDDBs with the COPY Procedure. MDDBs that are stored on the remote hosts are then available for reading.

Accessing MDDBs Via CEDA

To access MDDBs with the Cross Environment Data Access (CEDA) facility, you must have SAS/CONNECT software licensed on the host that will be accessing the file.

CEDA is a SAS Version 8 facility that provides read-only access of supported member types to all Version 8 operating environments except CMS. For complete details on CEDA, see SAS/CONNECT User's Guide and Moving and Accessing SAS Files across Operating Environments.

To make an MDDB available for reading via CEDA, use Network File Services (NFS) to mount the file on a network for host access. Ensure that the file has the appropriate filename extension (for example, .sas8bmdb for Version 8). See the documentation for NFS and your operating environment for details. When the file is mounted, any Version 8 host (except CMS) with access to the NFS can then read the MDDB.
