Sonarqube on prem not starting

my sonarqube application/webportal is down,I have tried to bring it up but failed to do so,any help here?

I am using oracle database

Hello @kagabaj and welcome to the Community! Could you have a look at your server logs and see if there are any errors logged there? In particular, sonar.log is the file that most likely contains some hints, assuming your issue is with the startup. If the issue is with the web app, then you might find more hints on web.log.

I have actually checked on both files and I don’t see special error preventing the startup.

kindly support,regards

Could you share the logs here?

In sonar.log, do you see something like this:

2026.06.16 13:24:37 INFO  app[][o.s.a.SchedulerImpl] SonarQube is operational

And in web.log, something like this:

2026.06.16 13:24:34 INFO  web[][o.s.s.p.Platform] Web Server is operational

here are sonar.log
