Potential solution to Golden Gate error message "Parameter [INTEGRATEDPARAMS] is not valid for this configuration"

I was trying to set up an Integrated Capture in my Golden Gate environement, and kept getting the following error when starting my extract process:

OGG-10144  Oracle GoldenGate Capture for Oracle, myext.prm:  (myext.prm) line 3: Parameter [INTEGRATEDPARAMS] is not valid for this configuration.
ERROR   OGG-01668  Oracle GoldenGate Capture for Oracle, myext.prm:  PROCESS ABENDING.

In my case, this was caused by the fact that the extract was configured with classical capture, like this:

ADD EXTRACT MYEXT, TRANLOG, BEGIN NOW

The correct way to configure an extract in integrated capture mode is:

ADD EXTRACT MYEXT INTEGRATED TRANLOG, BEGIN NOW
