NOTICE DATE: March 19, 2008 NOTICE TYPE: M-A031708-03 UPDATE Extracts - Wholesale/Retail CLASSIFICATION: Public SHORT DESCRIPTION: ERCOT is continuing to experience delays with posting several data extracts/reports. INTENDED AUDIENCE: All Market Participants DAY AFFECTED: March 15, 2008 to current LONG DESCRIPTION: ERCOT is experiencing delays with some extracts/reports due to an internal system issue. ERCOT anticipates being current with extracts and reports by this coming weekend. The following extracts/reports are posting one day later than expected. There is no gap in the data and no other extracts are affected at this time.

Root Cause: The delays in posting the above listed extracts and reports are due to compounding issues. ERCOT performed a data cleanup on Friday, March 14, 2008 resulting in the backout and rerun of three Operating Days. Each job in the delayed batch had to be manually executed and monitored. On Saturday, the batch execution times were significantly slower than expected runtimes. On Monday, database statistics were performed to resolve the batch performance issue. At this time, ERCOT is focusing efforts on eliminating the one day delay in batch execution. The current plan has the batch process returned to normal schedule by Monday, March 24, 2008.
