Hi Deepak,
What are some 'low-cost good-quality' tools that you can recommend (or have
an experience with), to compare performance before we cut-over to Linux?
The best and most effective "low-cost" tool is code instrumentation (e.g.
DBMS_APPLICATION_INFO, DBMS_SESSION or its driver equivalents + recording).
You can easily compare the performance, if you measure and record your
applications / business processes. However this needs to be implemented by the
developers and is not a plain database feature, which can be enabled.
I have also read about BenchMark factory, HammerOra, JMeter, SwingBench and
SLOB. Any thoughts?
All of these tools have different scopes. I used SLOB for platform I/O
performance, SwingBench for synthetic (TPC like) application tests and JMeter
for replay of the real application load / behavior. However JMeter needs to be
setup by your developers and application owners as it needs to be
recorded.

To recap, this is a 170TB DB, generating 5TB archive a day (even after a lot
of operations as nologging).

The Oracle's Real Application testing (RAT) is an option but could be very
expensive. I have also read about BenchMark factory, HammerOra, JMeter,
SwingBench and SLOB. Any thoughts?
Thanks,
