Resolving ORA-01033 "initialization or shutdown in progress"
First:

sqlplus /nolog 


Then:

connect / @bdlocal as sysdba 


(Alternatively, use sqlplus / as sysdba instead of the above two steps.)

Check the status (I guess it will tell you anything but STARTUP):

select status from v$instance; 


Then turn it completly off: 

shutdown immediate; 


Then start it:

startup;


If you get errors starting up, check the alert log and your favorite search engine (searching for the ORA-xxxx alert number is a good place to start). If you can't figure it out, you can ask a question about that here (including the relevant part of the alert log or any other errors you see).
