A few days ago I did a system upgrade to fedora 27 and since then the oracle service doesn't properly start the database, I mean after running:

sudo service oracle-xe start

the database still down. but if I login as the oracle user and then execute the contents of startdb.sql:

connect / as sysdba
startup
exit

everything works as usual. I think the problem is caused by some misconfiguration, but I don't know where to look.

Running systemctl status oracle-xe only shows that the database is not active:

This is what journalctl reports from oracle-xe service's start method:

If I run lsnrctl start after calling sudo service oracle-xe start the database becomes alive again.

This is typically caused by some leftover socket files at temporary locations with wrong permission (for example someone started the listener as root). Shut down the database and delete those file as:

rm -rf /var/tmp/.oracle

Then try again.

  • there were 2 files owned by "1001" deleting that folder did the trick – moscoquera Jan 28 '18 at 23:09
