Check logs for errors and done!

On every new install, I like to add en “dummy” entry on /etc/oratab for an easy env load, but this is just me.

[oracle@olinux8 ~]$ . oraenv
ORACLE_SID = [oracle] ? dummy
The Oracle base has been set to /u01/app/oracle
[oracle@olinux8 ~]$ $ORACLE_HOME/OPatch/opatch lspatches
