  3. SAIG System Diagram SEND/ RECEIVE PC Destination - EDconnect Title IV Appsys SEND/ RECEIVE Encryption Internet (SSL 3.0) SEND/ RECEIVE SEND/ RECEIVE MF Destination Point Using EasyAccess/TDClient TDN/ @ VDC Authentication Manage/ Report TDManager @ VDC Manage/ Report Remote Administration

  4. SAIG Security • TDClient v2.2.x (formerly EasyAccess) is the client software used to send and receive FTP data transmissions securely over the Internet using SSL 3.0 and the Diffie-Hellman Dynamic Key Exchange algorithm. • Since TDClient is built into current versions of EDConnect, the level of security is identical between EDConnect and TDClient running on a mainframe. • Password: Same as that used and set in EDConnect for SAIG access

  5. TDClient: Systems Supported • OS/390 MVS/ESA 2.6+ (with LE/370 1.9) • AS/400 4.2+ (Compiler Level 3.7) • AIX 4.2+ • Digital Unix 4.0 (DEC UNIX) • DEC Open VMS 7.1 • HPUX 10.01+ • Sun Solaris 2.6+ (SPARC chip only, Intel chip not supported)

  6. TDClient Software & Documentation • Software • TDClient is available only upon request by contacting CPS/WAN Technical Support at 800-330-5947 or via email at cpswan@ncs.com. • Documentation • Host Communication Guide is available for download from the FSA Download website, http://FSAdownload.ed.gov

  7. CSU Process Overview • Receiving Message Classes • 1st job in nightly production schedule • Establish secure connection to SAIG • Download available message classes • Only those we have identified • Decompress • Backup message classes • Move message classes to appropriate datasets • Available for subsequent jobs during the same nightly run • If a downloaded message class is a COMRECOP: • The same “receive” JCL initiates CASX50 • XML documents are parsed and datasets created • ORSPx, DRSPx, PNOTEx, etc. TDClient

  8. CSU Process Overview • Sending Message Classes • Production job runs generating an outbound message class • Establish secure connection to SAIG • Message class is compressed • Message class is sent TDClient

  11. TDClientManager • Manage message classes in your SAIG mailbox • Check status • Change password • Repost message classes • Access to message class archive • http://www.saigportal.sfa.ed.gov/

  12. Data Warehousing @ CSU • Purpose • Make financial aid data available to other departments on campus • Office of Budgets and Institutional Analysis • Research • Other departments and colleges • Aid in awarding scholarships

  13. Data Warehousing @ CSU • Process • Job runs nightly extracting data from SAM • Dataset is FTPd to an Oracle database running on an AIX box • SAM warehouse tables updated • SAM fields warehoused • http://delphi.is.colostate.edu/dictweb/dictw001$.startup
