Good morning, I’m Barbara Beccati.
I’m an electronic and telecommunications engineer.
I obtained my bachelor degree in 2005.
Between August 2007 and July 2008, I was Technical Student at CERN: my project was about the development of the system test for the LHC tune measurement and abort gap monitoring.
I obtained my Master degree in July 2008 and I started my Marie Curie fellowship programme at CERN last august, three months ago.
I’m working in the CMS section, the Compact Muon Solenoid experiment.
SINCE 2008, AUGUST 1st

Oracle Portal Technology and Development Tool
First Results and Objectives
In this presentation,
I will describe:
the Compact Muon Solenoid (CMS) experiment
the Oracle Portal Technology and Development tool
The first results and the objectives of my project

4. The Compact Muon Solenoid DAQ Baseline Structure
CMS
The Compact Muon Solenoid (CMS) experiment is one of the general-purpose particle physics detectors built on the Large Hadron Collider (LHC) at CERN.
The main goal of the experiment is to discover new rare particles.
To have a good chance of producing a rare particle a huge number of proton-to-proton collisions is required.
For this reason particle bunches in the LHC collide up to 40 million times a second.
But not all these collisions are interesting for our porpouses: fast electronics filter only those events (around 100 per second) most likely to show new particles.
In CMS we can find several filter levels.
The first one reduces the data rate from 40 MHz to 100 kHz.
These data are read in parallel by fats readout system are combined into a single event.
This event is processed by a second filter which reduce the data rate to about 100 Hz.
Thousands of pc are involved in this procedure: CMS is a very complicated machine, made of several components whose parameters require a carefully monitoring.
Collision rate MHz
Level-1 Maximum trigger rate kHz
Average event size ≈ Mbyte
Event Flow Control≈ Mssg/s
No. of In-Out units
Readout network bandwidth ≈1 Terabit/s
Event filter computing power ≈106 SI95
Data production ≈Tbyte/day
No. of PC motherboards ≈Thousands

Database
Portal
Technology
In order to organize and make easier the monitoring of all the data of the several CMS components, the portal technology has been chosen.
Throw a portal it’s possible to publish information from databases and other sources.
For example we can organize in the same portal
- information coming from the database of the enviromental parameters
- Data from the computing DAQ clusters
- Information coming from the HR databases
All this information can easily be accessed from the users, who receive a single-source experience.
Oracle Portal technology has been chosen because it allows to quickly build, administer and deploy portals. Moreover Oracle applications are standard driven, scalable and secure.

PORTAL

6. Oracle Portal and Portlets
WHAT IS A
PORTLET
A portal is made up of groups of pages hosting many different types of content that come from many different sources, all presented from a single location, the portal itself.
A portlet is a reusable, pluggable Web component that can draw content from many different sources.
Portlets provide a means of presenting data from multiple sources in a meaningful and related way. Because different portlets can be placed on a common page, the user receives a single-source experience.

Technology
Oracle
JDeveloper
PL/SQL
Java
In order to develop portlets it is necessary to be be familiar with several technologies.
The Oracle Portal Technology offers several technologies to develop, manage and administrate portals.
The Oracle JDeveloper is an integrated development environment. It offers features for development in several languages like Java, XML, SQL and PL/SQL, HTML, JavaScript. JDeveloper covers the full development lifecycle from design through coding, debugging, optimization and profiling to deploying.
JSP

8. First Results Acquisition of a global view of the Oracle Portal
Technology
Training with the Oracle JDeveloper Tool
Java, HTML and SQL concepts review
JSP, JavaScript, PL\SQL studying
Since 1st August
until November
Portlet Development for the Shiftlist Database
In practice
From the beginning of my contract I was mainly involved in Oracle training activities in order to
Acquire a global view of the Oracle technology
Learn how to use the oracle Jdeveloper tool
Review Java, HTML and SQL concepts
Study Jsp, Javascript and PL/SQl
Since the 1st of August until now, I have been mainly involved in training activities in order to acquire a global view of the oracle technology.
I have been learn how to use the Oracle Jdeveloper tool to develop portlet, I reviewed and updated my knowlegies about JAVA, HTML and SQL languages and studied elements of JSP, Javascript and PL\SQL.
I’m developing portlets for the Shiftlist database, a database used to store the information about the work hours shifts in CMS section. The users have different roles and grants. This database is manage and administrate using the oracle Portal Technology.
This is an example of portlet that I developed. Using this portlet, users can send an . This portlet can be added in a portal page, allowing a mailing service from the page itself.
I have followed the Java 5 course about the new language features. I found this course very useful to update my knowlegies about the most interesting addition to the java language introduced by the version 5.

9. Further Objectives Until
March 2009
Introduction to the project and to the Oracle Portal Technologies
J2EE Web Application course: JSP developing and new standard libraries
Oracle courses: development and management in Oracle environment
Further CERN
Training
Mastering the Oracle JDeveloper tool
