How to Trace Goldengate process?

Scenario:  Goldengate process is running very slow, Goldengate is blocking itself. We want to trace  goldengate replicat. When we trace, goldengate process write process information to trace 


Turn on Tracing 

Here in this scenario, I am tracing replicat 

GGSCI (tnc301) 5> send replicat RNLGGSM1, trace rnlggsm1.trc

Sending trace request to REPLICAT RNLGGSM1 ...
Trace file /usr/local/opt/oracle//112106/rnlggsm1.trc opened.

Turn off Tracing 

GGSCI (tnc301) 6> send replicat RNLGGSM1, trace off

Sending trace request to REPLICAT RNLGGSM1 ...
Closing all trace files..
