Eddie Awad blogs about "How to Give Your System a Break from Oracle XE".
---
There was a question on OraQA about how to stop Oracle XE from starting up with your computer. When you install Oracle XE on Windows, it creates a service called ?OracleServiceXE? with a startup type of ?Automatic? which means that the service starts automatically when the computer boots.
One way to prevent Oracle XE from starting up automatically is to change the startup type of the Oracle service to ?Manual?. You can do that by navigating to your Control Panel -> Administrative Tools -> Services, double click on the Oracle service and change the Startup type to Manual.
Another way to prevent Oracle XE from starting up automatically when Windows starts is to use the ORADIM command-line tool that is available with the Oracle database. From the DOS command line execute the following:
oradim -edit -sid XE -startmode manual
Now, when you want to use Oracle XE, you start it up like this:
oradim -startup -sid XE
And you shut it down like this:
oradim -shutdown -sid XE
Or you can use the ?Start Database? and ?Stop Database? shortcuts installed with Oracle XE. Navigate to Start -> All Programs -> Oracle Database 10g Express Edition ->Start/Stop Database
Now you know how you can squeeze out a bit of extra performance from your computer when you are not using Oracle XE :)

Ruby on Rails with Oracle FAQs by Casimir Saternos
What is Ruby?
Ruby is an object-oriented interpreted scripting language created by Yukihiro Matsumoto. Since the mid 1990s, it has grown in popularity in Japan and has gained recent attention as the language behind the Rails framework. You can use the language for a striking variety of functions?from basic scripting to creating Windows applications to developing Web applications. You can start using Rails without extensive knowledge of the language; the Rails framework generates the fundamental classes needed for the Web application and uses reflection to perform object-relational mapping to the database.

Ruby on Rails on Oracle XE
As you may have noticed, Oracle recently published an article about Ruby on Rails on Oracle. This articles introduces the Ruby on Rails framework and explains how to use it to access an Oracle database (Oracle Database 10g Express Edition (XE), to be precise).
If you are not familiar with Ruby on Rails, it is important to note that it has nothing to do with Java; it is a Ruby-based framework. Ruby on Rails is really interesting, powerful.

Installing Oracle XE under Debian/(K)Ubuntu - it is easier than Windows by Jeroen van Wilgenburg

Translation in APEX - Mini how-to
Hi all,
I will try to give You my example of solving translation of application in APEX.
Main parameters:
Primary language: en (English)
Translation lang: hr (Croatian).
Read more
1.Firstly you have to define primary language (Application Builder>Application 500>Edit Globalization Attributes) and select your primary language (Application Primary Language: English (en).
2. On the sam page define Application Language Derived From as "Application preference (use FSP_LANGUAGE_PREFERENCE).
3. Define translation mapping "Application Builder>Application 500>Shared Components>Translate Application>Application Language Mappings" and create mappings for your second language (example is hr (Croatian)).
4. On the login page or first page if you don't have login, create hidden field (P101_LANG i n my example replace for your usage). It is used for rememebering current language
5. Create new application process (Application Builder>Application 500>Shared Components>Application Processes)
Name: redirect
Process point: On load before header
Type: PL/SQL Anonymous block
Conditions>condition type: Request=Expression1
Conditions>Expression1: LANG
Process text (here is the code):
BEGIN
IF nvl(:P101_LANG,'en')='hr' THEN
:P101_LANG:='en';
ELSE
:P101_LANG:='hr';
END IF;
HTMLDB_UTIL.SET_PREFERENCE ('FSP_LANGUAGE_PREFERENCE',:P101_LANG,:FLOW_USER);
owa_util.redirect_url('f?p='||:APP_ID||':'||:APP_PAGE_ID||':'||:SESSION);
END;
6. Login page: on this page create one button with label in your primary lang. point on second language. My example label is "Croatian" in english as primary language and translated to "English" in Croatian. This logic is used for having just one button saying "Croatian" when I'm in english web page and "English" when I'm in croatian web page.
Button has "Optional URL Redirect" with :
Target is: page in this application
Page : your login page number (most probably 101)
Request: LANG
7. For all other pages i use new item on navigation bar defined as:
Label: Croatian (secondary language) in Croatian translation label is "English"
Target>Target Type: Page in this application
Target>Page: &APP_PAGE_ID. (don't forget dot on the end)
Target>Request: LANG
8. Export XLIFF
9. Translate
10. Import translation
11. Publish translated app
12. Enjoy
That's all folks.
Main logic is to create same process for every page that is triggered if the request is LANG. This process changes the FSP_LANGUAGE_PREFERENCE preference that as far as I know can not be changed as other common app parameter but using HTMLDB_UTIL.SET_PREFERENCE function. With hte process in place you just have to implement link on every page for itself with request=lang and tha language will change.
I hope this is useful for everybody because it took me 6 bloody hours to do figure it out.

DBA Interview Questions
- Explain how you would restore a database using RMAN to Point in Time?
- How does Oracle guarantee data integrity of data changes?
- Which environment variables are absolutely critical in order to run the OUI?
- What SQL query from v$session can you run to show how many sessions are logged in as a particular user account?
- Why does Oracle not permit the use of PCTUSED with indexes?
- What would you use to improve performance on an insert statement that places millions of
rows into that table? - What would you do with an "in-doubt" distributed transaction?
- What are the commands you?d issue to show the explain plan for "select * from dual"?
- In what script is "snap$" created? In what script is the "scott/tiger" schema created?
- If you?re unsure in which script a sys or system-owned object is created, but you know it?s in a script from a specific directory, what UNIX command from that directory structure can you run to find your answer?
- How would you configure your networking files to connect to a database by the name of DSS which resides in domain icallinc.com?
- You create a private database link and upon connection, fails with: ORA-2085: connects to . What is the problem? How would you go about resolving this error?
- I have my backup RMAN script called "backup_rman.sh". I am on the target database. My catalog username/password is rman/rman. My catalog db is called rman. How would you run this shell script from the O/S such that it would run as a background process?
- Explain the concept of the DUAL table.
- What are the ways tablespaces can be managed and how do they differ?
- From the database level, how can you tell under which time zone a database is operating?
- What?s the benefit of "dbms_stats" over "analyze"?
- Typically, where is the conventional directory structure chosen for Oracle binaries to reside?
- You have found corruption in a tablespace that contains static tables that are part of a database that is in NOARCHIVE log mode. How would you restore the tablespace without losing new data in the other tablespaces?

Centralny serwer logów MS Windows na PostgreSQL
Zachęcam do zapoznania się z ciekawą koncepcją połączenia systemu logów MS Windows'ów z darmową bazą danych PostgreSQL. Autorem koncepcji i aplikacji jest Bartek Siębab.
Głównym założeniem projektu była centralizacja logów zbieranych z różnych systemów MS Windows z dzienników evenlog oraz innych (za pośrednictwem protokołu syslog) w jednej darmowej bazie SQL. Z powodu wymagań co do wydajności bazy, objętości gromadzonych dzienników oraz faktu iż baza ma być darmowa, sql'owa i ma być bazą (a nie programem do wyświetlania tabelek takim jak "mójsql" ;-) a ponadto koniecznym "połączeniem" do bazy w postaci komponentu .NET 2.0 na placu boju pozostał PostgreSQL...
