GoldenGate Extract is lagging behind with the data source

edited Apr 25, 2014 12:00PM in GoldenGate, Streams and Distributed Database (MOSC) 5 commentsAnswered

Hi,

The extract is lagging behind with the data source and I can see there is lot of redo generation due to some application load.   Could you please shed some light as how to reduce this lag..

Your early response is very much appreciated.
