Description of the problem: ogg can't stop the extraction process when it stops
GGSCI (ex02db02.iris.cl.sh.cos) 6> stop extu6 Sending STOP request to EXTRACT EXTU6 ... There are open, long-running transactions. Before you stop Extract, make the archives containing data for those transactions available for when Extract restarts. To force Extract to stop, use the SEND EXTRACT EXTU6, FORCESTOP command. Oldest redo log files necessary to restart Extract are: Redo Thread 1, Redo Log Sequence Number 2010, SCN 0.2340216775 (2340216775), RBA 2150464016 Redo Thread 2, Redo Log Sequence Number 3767, SCN 0.2578644069 (2578644069), RBA 3712786960.
