NiFi CLI Tookit : set-param

Hello,

I have tried to use nifi cli toolkit (nifi 1.11.4) to set parameter like this. However, I can't see any effect.
What have I doing wrong?

#> nifi get-param-context -u http://localhost:8080 -pcid 828f0882-0177-1000-aabd-d680a070c5c5

# Name Value Sensitive Description
- ------------- ------------- --------- -----------
1 sample.Passwd ******** true
2 sample.Schema SAMPLE001 false
3 sample.URL jdbc://sample false
4 sample.User dbsample false

#> nifi set-param -u http://localhost:8080 -pcid 828f0882-0177-1000-aabd-d680a070c5c5 -pn sample.URL newvalue
Waiting for update request to complete...
