Good morning,

I forgot the system password for my Oracle XE installation to my Ubuntu Server computer.  Is there any way I can rest that password?

Thanks so much,


Jazon

tangchunfeng is correct, but make sure that your ORACLE_SID variable is set first:

su - oracle (or just login as the "oracle" unix user)
echo $ORACLE_SID (If this is already set to the name of your database, then stop here)
cat /etc/oratab (or maybe /var/opt/oracle/oratab. This lists all databases on the server)
ps -ef | grep smon (This will list the names of all databases that are up-and-running on the server)
. oraenv
(Enter the name of your database when prompted, in UPPER case)

This will setup your environment to point to the correct database, otherwise your "sqlplus" won't know which database to connect to.
