I'm a programming student and I just started learning databases in college. However, everytime I try connecting to my databse in Oracle SQL Developer I have this message:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor.
After posting here, we came to the conclusion that the databse wasn't properly started. When I try to start it from the cmd I get those errors:
When I type "startup" in the SQL command prompt
ORA-01078: failure in processing system parameters ORA-00600: internal error code, arguments: [kspifisp:ksfdread_resilver], [0x000A9F388], [0x000A9F000], , , , , , , , , 
When I type "select instance_name, status from v$instance;" in the SQL command prompt
ERROR at line 1: ORA-01034: ORACLE not available Process ID: 0 Session ID: 0 Serial number: 0
I've seen that I could go into the net manager in "Programs > Oracle - HOME_NAME" but I don't have this in my programs list. Of course I tried uninstalling and reinstalling the database several times.
I've done the same installation on my PC at home and everything works fine I just need to make it work on my school laptop. I'm currently on Windows 10 installed on a Macbook. The database I installed is Oracle Database Express Edition (XE) Release 18.104.22.168.0 (11gR2).
Here is the 'init.XE.ora' file
