  2. Agenda and Commentary • Retail transaction processing unplanned outages: Storage disks generated an error resulting in an outage of the Retail Transaction Processing application on two occasions - 4/1 (148 Minutes) and 4/12 (149 Minutes). Data integrity scans were performed before restoring the application. An architectural change was implemented as the final resolution. • Systems Issues at the end of April: Information Technology staff implemented a large number of software and infrastructure changes from Thursday April 29th through Sunday May 2nd.  Inadequate testing and failure to correctly restart services resulted in impact to both internal ERCOT business units and Market Participants.  Recovery procedures were implemented throughout the weekend to minimize the issues.  Impacts were to both Zonal systems and Nodal Market Trials.  • Major Impacts: • Eleven daily market reports were not available per Protocol requirement • Retail Transaction Processing was delayed on Monday • The Nodal Network Model Management system was unavailable; and, • Some users experienced report access, slow response, and system access issues

  3. Agenda and Commentary • Delayed posting of data extracts: Posting of EMMS-related data extracts was delayed from 4/30 to 5/04 due to replication issues between EMMS and Enterprise Information System (EIS) following a software change in the April 29th release. A workaround has been put in place and all extracts were made current by May 5th. A permanent resolution will be implemented by May 6th. • Planned system change “Freeze”: Effective May 3rd, in preparation for Nodal “Go-Live”, all system changes are being limited until after Nodal implementation. Any change other than Nodal changes or emergency changes must go through the CEO Review process for exception approval.
