I did make clone of virtual production system and after start clone I was trying to change hostname of Qradar All in One using this procedure.
Changing the network settings in an all-in-one system
After running qchange_netsetup it asks for new network setting.
If we change hostname procedure fails with error message taht tomcat can't be initialized.
I did try to change IP only and it works fine.
Any advice. Do somebody has some practical experience from hostname chage of Qradar AIO system?
Thanks for advice.
There is a bunch of things that could be the problem. Best to open up a case with QRadar Support team for investigation.
