问题
I've been trying to create PL/SQL packages and running procedures on a local installation of Oracle 11gR2 on my computer, and I kept getting ORA-00900 error. Based on this article, it seems like Procedural Option has not been not installed.
This is the output of sqlplus when I logged in:
C:\Users\NgCH>sqlplus
SQL*Plus: Release 11.2.0.1.0 Production on Thu Feb 14 13:11:34 2013

How can I install it? If I've to reinstall Oracle, what are the options I must choose in the installer? I chosen Enterprise Edition, Desktop Class.
Thanks.
Edit:
This is very simple package code I tried to execute in DBeavor (64-bit) v2.0.6, to a local Oracle database with Oracle thin connection:
CREATE OR REPLACE PACKAGE TEST AS
hello_world constant varchar(20) := 'hello world';
END TEST;
Error from DBeavor:
Error occurred during SQL query execution
Reason:
SQL Error [900] [42000]: ORA-00900: invalid SQL statement

I've followed the advice in the comments and learnt that my problem isn't with my Oracle database installation at all.
I was using DBeaver while attempting to run some pl/sql script, and for some reason I don't know it failed with the ORA-00900. After posting the question I ran the same script in Toad for Oracle, and it works without any problem. Running the same script in SQL Plus also works okay.
I don't know what causes the error in DBeaver yet, but at least now I know the error code ORA-00900 does not mean my database is missing any Procedural Option function. In hindsight I probably should have tested my script in SQL Plus first before posting the question.
Anyway, thanks for the comments guys, it really helped me tons.

DBeaver cannot execute PL/SQL as they view it as Oracle specific, which it is. This may be implemented some time in the future.
