I`m new to matlab and I need some help about poles and tf?

(s+17)/(s^3+10s^2+17s+114)
Sys=tf([1,17],[1,10,17,114])
Pole(sys)
ans =
-9.4756 + 0.0000i
-0.2622 + 3.4586i
-0.2622 - 3.4586i
Root(sys)
ans =
-17
Pzmap(sys)
1) Can you explain open loop stability?
2) How do I know if this system oscillate? Why?

Use root locus plot and step response simulations that will answer to your questions, e.g.:
Sys=tf([1,17],[1,10,17,114]);
pzmap(Sys)
figure('name', 'Root-locus')
rlocus(Sys)
figure('name', 'Step-response')
step(Sys)
