DESCRIPTION:
ERCOT conducted an emergency database failover on April 21, 2008
following a hardware failure. This
database failover resulted in an out-of-synch (OOS) data problem from April 21
through April 30. ERCOT has developed a phased process to
attempt to thoroughly recover the missing data.
Phase 1: Repair the
out-of-synch situation and begin posting daily extracts was completed as
expected. However, during the
course of executing Phase 2, a gap was exposed due to changes in the replication
strategy during the time period affected because of system upgrades and
migration. A modified Phase 2
recovery plan has been initiated and is outlined below:
Recover the EMMS data for April
21 through April 30, 2008 into ISM.
