How to reset/flush startup configurations on Ubuntu 18.04

Chronology :

  1. installed tomcat8 through apt, then nothing configured (i leave it as is)
  2. copy-paste some tomcat folders from another machine, and it could started
  3. then i encountered symptom : the tomcat process cannot immediately serving the user. When accessed through browser, it loading endlessly.
  4. this symptom lasted for about 15 to 30 minutes. I never estimate it correctly. According to the admin of the other machine, this symptom doesnt occur. So it is definitely something on my machine

Questions :

  1. a friend of mine said to me to remove the tomcat8. Already done. Already purge. But still the symptom exists
  2. Perhaps i need to “reset” or “flush” the configurations to default. How to do this?
