Minutes from last TAG meeting – February 23rd 2006

3. MPCC Release

4. MPCC v11 upgrade All but two MPs now live at Version 11
Issues preventing upgrade are on the participant side and are unrelated to the upgrade
No issues relating to the MPCC release in any MP site since Go-Live in February
Receipt Acknowledgements have been received for all messages sent by ESBN since Go-Live.
Proposing to close this item

5. Review of Message Reconciliation and issue identification processes

6. Message Reconciliation Process
Procedures discussed at last TAG have now been documented and agreed across all relevant teams
Emphasis placed on communication to MPs where issues arise
Essential that 602 reconciliation is carried out at MP site

7. Message Reconciliation Process
ISC run queries first thing each morning to determine the number of messages sent and received by SAP
MOIEX run queries to determine messages in and out of the hub
Both figures are reconciled and corrective actions taken if necessary

8. Issue identification
Previous issues and the way with which they were dealt have been reviewed
RMDS team added to ISC contact lists in case of unplanned outages, message issues etc
RMDS will notify Market Participants where issues arise with market impact

9. Issue identification – 602 errors
Queuing delays with the audit data
Delays in data written to the audit queues should not impact as the message is generated 2 ½ hours after the reconciliation period (change applied late last year)
Should this occur, RMDS will notify MPs

10. Issue identification – 602 errors
Messages issuing through the night
Larger than usual volumes may mean that messages are running up to the 4 AM reconciliation time
If a message is sent at 3:59:59 it will appear on the 602 message although the MP may not have received it till slightly after the 4AM cut-off time
Where messages run late, RMDS will notify MPs

11. Issue identification – Pre-Production messages reaching Production
Errors occurred when rebuilding Pre-Production from Production following a disk problem with one routing table not successfully updated
There are no further hub amendments which can prevent this
Procedures on the SAP side have been refined and documented to ensure that routing tables are appropriately updated when a new client is built

12. Error identification messages

13. Error identification messages
Issue raised by MPs in advance of Version 11 of the MPCC
Number of changes made by Version 11 to make error messages less generic
Need to determine if this is still an issue?

14. Update from TLG

15. Update from TLG Forum for:
Communication and consultation around technical design proposals and plans for SEM
Co-ordination of industry-wide technical activities such as testing
Communication with other MPs regarding common implementation issues

16. Update from TLG
Second Technical Liaison Group meeting held on March 23rd
Reviewing items such as:
Data Access Model
Data Standards
Readiness Assessment

17. Update from TLG Overlap in attendance between both groups
RMDS will attend the TLG to monitor items with Retail Market impact
These will be discussed at the TAG
Important that MPs also raise any issues for concern/questions/proposals

18. Update from TLG Three options for data access:
Web service
Web Page Forms
Web Download
The next TLG (April 20th) will focus on a demonstration of sample schema
There will be a design freeze in place from June 7th

19. June Schema Release

20. June Schema Release Test version of schema to issue to MPs this week
Release to production intended for June 24th
Includes the following:
MCR TSO/SSA requirement for customer details on change from NQH to QH
MCR Addition of Effective from date to 114 message
MCR Addition of effective date of previous CoS to 102R message
MCR 0077 – Removal of GUID from webforms (No schema impact)

21. June Schema Release
Detailed Cutover and on the day plans to issue closer to the time
Assurance requirements to be determined by Gemserv

22. June Schema Release
Essential that all MPs upgrade on Saturday June 24th
Messages sent by ESB Networks after this date will be V 5.1 instead of V 5.0
If an MP does not upgrade on June 24th any messages to issue to them after the upgrade would fail
All messages sent by MPs would fail validation in the hub
For most MPs even one day of lost data would cause significant issues
MOIEX will channel all resources available into upgrading on the day – after this, all resources will be focussed on monitoring the first few days of live operations

23. Planned Outages and Maintenance Activities
