Review of Message Reconciliation and issue identification processes

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

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

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

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

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

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

Error identification messages

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?

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
