I have just installed Oracle 11gR2 on my Linux Mint Distro (xfce). All worked fine, and I was able to acces to
https://localhost:1158/em [Erreur 102 (net::ERR_CONNECTION_REFUSED) ]
I rebooted my PC and tried to reopen the page but this time I am unable to open it.
I am not so expert in Linux but could that be a problem of acces permission ?
How could I resolve this issue?
