ORA-01033: ORACLE initialization or shutdown in progress using Oracle Express
I believe restarting the applicable windows service will bounce the database.

net stop oracleservicexe
net start oracleservicexe


Alternatively you can connect as sys and provide the password instead of using internal authentication, then bounce the database from there.

&gt;sqlplus /nolog
SQL&gt;connect sys as sysdba
Password:


You may also want to check the alert log for what, if anything, is keeping the database from completing startup or shutdown.
