which of the processes should include the PURGEOLDEXTRACTS parameter to trigger trail file clean up?

If multiple GoldenGate processes are accessing a set of trial files which of the processes should
include the PURGEOLDEXTRACTS parameter to trigger trail file clean up?

A.
Manager

B.
Extract

C.
Replicat

D.
Both Extract and Replicat

Explanation:

In reference guide, page 256, and I quote “If multiple groups are reading the same set of trail files,
one process could purge a file before another is finished with it. Instead, use the Manager version
of PURGEOLDEXTRACTS, which is the preferred use of the parameter in all GoldenGate
configurationsbecause it allows you to manage trail files in a centralized fashion.”
