Problem :
I am newly installing the Oracle XE database on my Ubuntu by following below steps:
Downloaded the latest rpm file for the Oracle XE and ran below commands to install my database:
sudo apt-get install alien
alien oracle-xe-11.2.0-1.0.x86_64.rpm
dpkg -i oracle-xe_11.2.0-2_amd64.deb
After that I made sure that I have the permissions to /u01/ and also it is under the dba group.
Now when I am trying to start my database then I am facing below error
“Ora-00205: error in identifying control file, check alert log for more info”
