A couple useful Oracle XE admin commands

I struggled a bit trying to get my local Oracle XE up and running after a couple months of being dormant.

Firstly: Oracle XE 11g sets password expiry by default. Quiet annoying...
So my system account was locked.
How to unlock that I did the following on the window command prompt:
set ORACLE_SID=XE 
set ORACLE_HOME= "ORACLE_PATH" (D:\OracleXe\app\oracle\product\11.2.0\server) in my case.
sqlplus / as sysdba
ALTER USER SYSTEM identified by password;

If the account is locked run:
ALTER USER system ACCOUNT UNLOCK;


Then, to ensure that it does not expire again:

ALTER PROFILE DEFAULT LIMIT
FAILED_LOGIN_ATTEMPTS UNLIMITED
PASSWORD_LIFE_TIME UNLIMITED;

One more thing I needed to change since I had installed a local Tomcat, is the default HTTP port for XE.
This can be done with 3010 is the new port:
Exec DBMS_XDB.SETHTTPPORT(3010)
