UK Link Technology Refresh Annie Griffith & Chris Fears September 2007
Progress since last update Key progress made since last update: • Development and Unit testing completed • Installation and configuration of all servers and networks at Peterborough Data Centre and Wellingborough completed • Network Operations Centre (NOC) set up in Bangalore and operational • System testing started • Operational Acceptance testing Started
Overall Testing Progress • Full code migration and upgrade completed • OAT – 2 phases Jun-Oct ’07 & Oct-Jan ‘08 • OAT1 – machine build confirmation – Ahead of schedule • OAT2 – performance testing, operational schedules, support processes, fall back and recovery etc. • System testing : Started mid Aug and ahead of schedule • Users involved in testing of critical business components to gain greater levels of assurance ahead of UAT • UAT : Nov – end Jan • To include Shipper Trials : late Nov - early Dec • Detailed UAT planning underway • Full scale trial migration completed – • Minimum of 2 further full scale trial migrations planned to allow for tuning
Shipper Trials • Initial suggestion was that only file routing tests to be executed, limited to sample files only • As a result of UKLC July 07 request, revised approach is to test: • Nomination file (NOM) – inbound and Nomination response (NMR) outbound • Commodity Invoices (COS) – outbound, with inbound delivery receipt • Datalogger Read files (MDR) – outbound • Involvement is optional • Code of Conduct: The test environment is not to be used for any other activities ie: enquiries other than the scenarios and data agreed by each Shipper
Shipper Trials • Trial environment will be a copy of production data as of 1st October 2007 • Shippers to save selected copies of production NOM files between 1/10 – 12/10and rename • Between 3 and 5 NOM files are to be saved for future processing • Use standard test file naming convention: xxx01.TN123456.NOM • Earlier files will result in fewer queries due to better alignment with data-cut • Submission of files to take place before 12 noon • Response files will be processed and sent back the following day by 10.00am (The test file turn-a-round time will not be representative of Production) • Test files to be submitted in date order • No xoserve validation of rejections at MPRN level will take place
Shipper Trials Assurance & Sign-off • Individual Daily Test Reports will be produced by the Test Coordinator and issued at end of day • On conclusion of the Shipper Trial phase xoserve will confirm final test position (by e-mail) with each participating Shipper • Teleconference meeting to take place at the end of testing • Capture lessons learnt • Confirm any outstanding issues • Discuss remedial action plans (if necessary)
Cut-over and Implementation • Outage of 3 - 4 days as previously indicated • Detailed implementation planning activities ongoing • Looking at cut-over activities and catch-up processing • Timescales being challenged, seeking alternative approaches and tuning to reduce outage • Minimum of 2 further full scale trial migrations planned over summer • MOD proposal being drafted to include: • 2 non-effective days for SPA processing (25th & 26th Feb) • 4 days relief from data logger liabilities (24th-27th Feb)
Cutover Approach • Data cutover • Likely to start 3 weeks in advance of main cutover, then will require “delta” data updates • This will have no effect upon the operational service • Final cutover starts 22nd/23rd February 2008 • REC invoice to be issued early on Friday 22nd – due dates will be unchanged • Other production runs on 22nd will be unchanged • Outage start time • Start after Datalogger issue on Saturday 23rd confirmed as optimal approach
High Level Timetable (Draft) • Invoices • Friday 22nd - REC Invoice issued early, due dates unchanged • Non-effective Days • Mon 25th Feb - Tuesday 26th Feb • Relief from DM Read liabilities Sun 24th –Weds 27th • Datalogger files • Issued from OLD UK Link Sat 23rd • Suspend daily issue of data logger files Sun 24th – Weds 27th • Issued from NEW UK Link Thursday 28th • Transfers • Last files processed 11pm Friday 22nd Feb on OLD UK Link • Next Transfer Run – Weds 27th Feb on NEW UK Link
Next Steps • Completion of OAT Phase 1 • Complete trial migration 2 • Invitations issued for Shipper Trials • Continue with more in depth Implementation Planning • Firm up on outage timings • Understand catch-up and return to normal operation • Dates when other systems will be brought back on-line/in-step • Report back at October UKLC
