Oracle CertificationProgram

The Oracle Certification Program certifies
candidates on skills and knowledge related to
Oracle products and technologies.
Credentials are granted based on a
combination of passing exams, training and
performance-based assignments, depending on
the level of certification. Oracle certifications
are tangible benchmarks of experience and
expertise that help you stand out in a crowd
among employers.
There are 5 levels of Oracle Certification
credentials:
Oracle Certified Associate (OCA),
Oracle Certified Professional (OCP),
Oracle Certified Master (OCM),
Oracle Certified Expert
(OCE)
and Oracle Certified Specialist (OCS).
These credentials are spread across 9
technology pillars and further broken down into
product family and product groupings.
Certifications are also defined by job role on
the Oracle Certification website.
The Oracle Certified Associate (OCA) :
credential is the first step toward achieving an
Oracle Certified Professional certification. The
OCA credential ensures a candidate is
equipped with fundamental skills, providing a
strong foundation for supporting Oracle
products.
The Oracle Certified Professional (OCP) :
credential builds upon the fundamental skills
demonstrated by the OCA. The Oracle Certified
Professional has a command of a specific area
of Oracle technology and demonstrates a high
level of knowledge and skills. IT managers
often use the OCP credential to evaluate the
qualifications of employees and job candidates.
The Oracle Certified Master (OCM):
credential recognizes the highest level of
demonstrated skills, knowledge and proven
abilities. OCMs are equipped to answer the
most difficult questions and solve the most
complex problems. The Oracle Certified Master
certification validates a candidate's abilities
through passing rigorous performance-based
exams. The certification typically builds upon
the fundamental skills of the OCA and the
more advanced skills of the OCP.
The Oracle Certified Expert (OCE):
credentials recognize competency in specific,
niche oriented technologies, architectures or
domains. Credentials are independent of the
traditional OCA, OCP, OCM hierarchy, but often
build upon skills proven as an OCA or OCP.
Competencies falling under the umbrella of the
Expert program range from foundational skills
to mastery of advanced technologies.
The Oracle Certified Specialist (OCS):
credentials are typically implementation-
oriented certifications targeting employees of
current Oracle partners, though the
certifications are available to all candidates,
partner or not.
These certifications are built on
very focused products or skillsets and provide
a solid measure of a candidate's level of
expertise in a particular area.
The Oracle Certified Junior Associate (OJA):
credentials target students in secondary
schools, colleges and universities who are
studying computer science focused on
Database or Java.
Requirements:
Oracle University offers different certifications
for different Oracle products and services. A
candidate chooses a certain certification that
he/she wishes to earn and then follow the
requirements for that particular certification.
Requirements may include passing an exam
offered by Pearson VUE, earning a prerquisite
certification, completing training, or submitting
a course verification form.
Prior to taking an Oracle Certification exam, a
candidate must register for a Pearson VUE
account and authenticate their CertView
account as well.
An exam voucher can be
purchased from Oracle University or the
candidate can register for and pay for the exam
directly on the Pearson VUE website without
a voucher.
Vouchers can also be purchase
from an authorized Oracle Partner. The
candidate should bring two valid forms of
identification; both must contain your
signature, one should contain a photo, one
should be government-issued.
A purchased exam voucher should be used
within 6 months or it will be forfeited without
any refund.
A candidate can prepare for the exam by
attending training and prep seminars, offered
by Oracle University and practice tests from
Kaplan and Transcender. These are optional
and not required to have a certification.
If the candidate failed the exam, a 14-day
waiting period should pass before retaking the
exam. The 2nd exam attempt must be paid in
full. If the candidate fails to show up on the
scheduled testing time and date, the exam will
be voided and no refund shall be given.
There
are restrictions for candidates who are coming
from Cuba , Iran, North Korea, Sudan, and
Syria . A candidate who is minor should have a
consent from his/her parent or guardian.
Typically, one exam is associated with a
certification. However, some certifications
require two. Aside from a passed exam, some
certifications requires the candidate to attend
training at Oracle University. For Java EE
Master certification, the exams are not
multiple choice, instead an assignment which
should be finished and an essay exam as well.
Both the Assignment and the Essay must be
completed within 6 months of purchasing the
Assignment. Failed Assignments must be
resubmitted within 30 days.
Some certification levels build on each other;
for example, an Associate certification is
required for Professional, while a Professional
certification is required for Master. The Expert
and Specialist certification does not have any
prerequisite certification like Associate.
Oracle
has recently introduced Junior Associate
certifications (e.g., "Java Foundations Junior
Associate 1Z0-811" exam) that targets school
and college students.
Oracle Certified Associate Java
SE Programmer I (formerly
the Sun Certified Java
Programmer)
The Oracle Certified Associate Java SE
Programmer (7 and 8) exam is the basic exam
required to demonstrate solid understanding of
Java as a programming language and is a
prerequisite to being a certified Programmer.
While most advanced certifications focus the
test on your knowledge of the API, this entry
level one focuses on variables, class and
interface definition, arrays, exception handling,
encapsulation, polymorphism and flow control.
Basic API knowledge is required about strings
and arraylists. The version 8 of the test was
made available as a final release since
12/2014, testing for the lambda language
construct and knowledge on the old
autowrapping feature of the language, while
also testing for the new API of date and time.
Oracle Certified Professional
Java SE Programmer (also
formerly the Sun Certified
Java Programmer)
Java Certification Path
Oracle's Certified Professional Java SE
Programmer (OCPJP) exam is the
fundamental exam required to demonstrate
solid understanding of Java and some of its SE
APIs and is a prerequisite to a number of the
other Java certificates.
It is designed as a fairly detailed test of
knowledge of the core features and constructs
of the Java programming language. It tests a
wide range of Java's APIs and core features,
starting from basics such as looping
constructs and variables, to more complex
topics such as Threads, Collections and
Generics . It does not cover specific technology
domains such as GUI creation, Web or network
programming , though it does cover part of the
APIs included in the standard library. The exam
tests how well a programmer has understood
the language constructs and mechanisms.
However it's not a goal of the exam to test
the programmer's ability to produce purposeful
or efficient programs. It does not test the
programmer's ability to write efficient
algorithms, for example, though it does test
knowledge of which collections should be
selected in order to implement efficient
algorithms without re-inventing the wheel.
It is assessed through an automatically
administered multiple-choice test system and
consists of 60 questions which the candidate
has 150 minutes to answer. At least 37
questions are needed to be correct to pass
(around 61%).
To take the test a candidate
must buy a voucher from Oracle
(approximately US$300 in the US, £150
(excluding VAT ) in the UK, AUD 316 plus tax in
Australia, Rs. 8000 plus taxes in India) and
book the test at least a week in advance.
The test consists of multiple choice questions.
In June 2011, Oracle moved from Prometric to
Pearson VUE as their test provider.
The OCPJP 6 exam tests a candidate on
knowledge of declarations, access control,
object orientation, assignments, operators, flow
control, assertions, string handling, I/O,
parsing, formatting, generics, collections, inner
classes, threads and the JDK tools. The test
is available in English, Japanese, Chinese,
German, Korean, Portuguese, Russian and
Spanish.
The OCPJP 7 exam includes a few new Java 7
features such as NIO 2, try-with-resources,
catching multiple exceptions, and fork/join
framework. The OCPJP 7 exam has 90
questions and one has to answer 65% of the
questions to clear it. In case, you have older
version of Java Programmer certification (such
as SCJP/OCPJP 6) then you can appear for
upgrade exam (1Z0-805) to get OCPJP 7.

Cisco launches Adelaide’s Smart City Studio

Welcome to programer Destination...

         

                Cisco has revealed the next phase in its project to make Australia a global leader in developing smart city projects, with the launch of Adelaide’s Smart City Studio.

According to Cisco, this launch marks a significant step forward in a broader transformation project that aims to position Adelaide as one of the world’s most advanced Smart Cities. This project started 18 months ago, when Adelaide qualified as a Lighthouse City in the Cisco Smart+Connected Communities program, sponsored by Adelaide City Council and the Government of South Australia.

The first phase of the project includes the deployment of a set of smart city services that will improve the efficiency of the city’s assets, including street lighting and on-street parking. Cisco is currently piloting public Wi-Fi through local partner, iiNet, and smart lighting and parking with global ecosystem partner, Sensity.

Cisco A/NZ vice-president, Ken Boal, said the move is a key launch for both the City of Adelaide and Cisco.

He claimed the Smart City Studio will connect the City of Adelaide, and its businesses, entrepreneurs and citizens to a range of IoT opportunities. The studio will be directly connected to Cisco’s Internet of Everything innovation centers around the world, as well as to other local innovation hubs throughout the country.

“It will enable tech innovators to work with other local and global innovation hubs, and develop IoT applications and services that will help the citizens in their everyday lives, as well as the city to reduce its expenses and drive efficiencies in operations, including reducing its environmental footprint.

“There are discussions underway with a number of cities and councils across A/NZ to better understand their specific needs, so we can develop and implement solutions that enable the delivery of new citizen-centric services and reduce expenses and drive efficiencies in operations,” he said.

Cisco senior vice-president for Smart+Connected Communities, Dr. Anil Menon, indicated Adelaide’s Smart City Studio is a space that will be dedicated to innovation, particularly in regards to the ground-breaking applications and services that can be built around IoT.

He added that it will enable innovators to develop, test and commercialise the next generation of IoT applications and services to improve citizens’ everyday lives. It will also provide access to a broad range of city-wide services, making the city more resource-efficient and environmentally sustainable.

“As a Cisco Lighthouse City, Adelaide is a test bed for implementing advanced IoE and IoT solutions for city infrastructure management and is one of the very few cities ready to develop and pilot new urban services and solutions to benefit the customer and citizen experience,” Dr. Menon said.

“Cisco’s Smart+Connected Communities team sees Australia as one of the next smart city countries. Adelaide is a fantastic example of what Australian cities can aim to achieve.”

This is one of several smart city initiatives by Cisco in Australia. Cisco has identified significant potential in several other Australian regions, including in South East Queensland.

Solaris Operating System.

Solaris is the UNIX-based operating system of Sun Microsystems with roots in the BSD operating system family. Up to the version 3.x this operating system was called SunOS, this name was kept into the internal release information of current Solaris versions. The first version of SunOS was published in 1982. With the version 4.0 the new product name Solaris was introduced for SunOS releases as of 1989. The operating system Solaris 2.0 (SunOS 5.0) basing on the UNIX system V release 4 was published in July 1992. 

The installation package of Solaris 8 (SunOS 5.8) is delivered on several CDs which include the operating system, applications and the documentation. With the Solaris Webstart 3.0 Installer Solaris can be installed comfortably on a prepared harddisk partition with at least 2 gbyte of free space. The Installer divides the partition into one boot partition (10 mbyte of size) and the Solaris System area inclusive swap area. 

The Primary boot subsystem VSN 2.0 proceeds after the Installation as a booting manager. After the booting procedure the CDE or optionally OpenWindow system is available as a GUI. Solaris fulfils the Open Group Unix98 specification. With the available Solaris Security Toolkit application it is possible to made specific protection settings for Solaris.

Solaris 8

Solaris 9

The supported languages (39) and local special features (162) were refined in this operating system release. At first the projects of Sun intended only to deliver new operating system releases for SPARC platform of their own. Because of the resistance from the public Sun supports x86 architecture now anyway furthermore. The download of the SPARC variant was possible at first, the x86 variant followed later. At first the download of Solaris/x86 was bounded with a small fee and since December 2003 without charge. 

The compatibility was improved to Linux in Solaris 9, standard libraries for Linux applications are installed now too. Security characteristic became extended, the new Resource manager tool with CLI and GUI as well as one new directory server where added. The file system was improved and extended with the SVM (Solaris Volume manager). New libraries were added for multithreading and the installation and configuration got improved. The execution of java applications with the Java Virtual Machine is accelerated by the new libraries now. As a desktop you can choose between the CDE (Common Desktop Environment) or Gnome 2.0 desktop . 

With the Live Upgrade Software patches or system modifications can be done without interruption of the running Solaris or his applications. To this the modifications are made in a second partition and Solaris installation and taken over at the next reboot in the main installation. After Solaris 9 8/03 this integration happens automatically. 

In Solaris 9 4/03 the maximum file size was increased from 1 tbyte to up to 16 tbytes. The system administration tool of SunMC 3.5 was revised, as a Web browser Netscape 7.0 is contained. 

Solaris 10

On 16-11-2004 became officially Solaris 10 for the x86 and SPARC architecture introduced and was ready for download on January 31st, 2005. It is delivered with programs for autodiagnostic and self-healing tasks. Programs for Solaris 9 can further be used in this new release. The operating system was changed to 64-bit and supports NFS 4.0 now, the IP-Stack was improved and improved with a new threading procedure. The effective forwarding of network traffic for 10 gbit and beyond per second is possible. Executing several instances of an operating system by virtualization on a common hardware base can be done with the technology Solaris Zones. In the project Janus the ability was developed for this operating system to be able to execute Linux applications after the recommends of the Linux standard base without new compiling. Planned for this release, this feature is not activated yet for Solaris. 

The new file system ZFS (Zettabyte File System) contains an integrated volume manager and support for logical Volumes which can be greater than 1 terabyte, however, this feature is not available in this Solaris release yet. The 128-bit file system called Dynamic File System (DFS) has self-healing and self-managing files with a maximum size of 2¹²⁸ bytes. The data files are mirrored permanently, checks all data blocks to faults by hash sums and repairs the copy or the original as well as if necessary the data storage. This happens transparently in second fractions without disrupted application software in the productive working mode. With ZFS practically unlimitedly big partitions and files are possible, the storage can be extended dynamically. A data block can be up to 128 kbytes of size, the size of the data blocks can vary. The compression rate makes it possible that files assumes only 50% to 33% of storage space. 

The service DTrace (Dynamic Tracing) tracks down performance bottlenecks at the execution of network applications, the fault manager provides a better stability and is part of the foresight and self healing concept which analyse errors in ahead and perhaps even clear the fault. To this the data are checked in the Kernel at 30,000 test points and a report created at negative signs for the administrator within less minutes. With this powerful tool it is possible to recognize problems earlier which was often before not or only heavily to trace back. 

With the technology Grid Container the administrator can set up disk partitions for every user so as if he works with an operating system of his own. Several users can share the system without disturb of the running applications. The system utilization is used considerably better and thousands of services/applications are managed better without large additional processor expenses. If necessary, services or applications can be provided to other users also about a network and separated from each other. 

Solaris 10 1/06 supports the SPARC, x86 and x64 architecture. As boat loader is grub used. The speed was optimized and it offers support for iSCSI and 10-gbit ethernet. Solaris 10 6/06 is the first official release of the Zettabyte file system (ZFS), supports SATA controllers and contains Xorg 6.9. 

The project Open Solaris was started officially in January 2005, a part of the source code was published. The work was started with support of Sun in a working group with 140 international subscribers for the disclosure of Solaris source code already in September 2004. The Solaris kernel as well as the system libraries followed in June 2005. In the course of the next months larger parts of the distribution followed under the CDDL (Common Development and Distribution License). The necessary patents also were provided to the Community under the CDDL. OpenSolaris does not see itself as a ready ready final user product or complete distribution. It rather offers the code base with developer tools for an operating system as well as the infrastructure for the communications under the developers. The ZFS (Zettabyte file system) is integrated since the OpenSolaris build 27a. 

Solaris express 6/05 (Nevada build 15) was published on June 21st, 2005. Sun provides under the concept of the Software Express program new monthly public Solaris releases for the Community. Furthermore the use of this operating system is free for private users, the commercial use is charged with $ 99 for a year. The Solaris Express releases for x86/SPARC almost based on the latest OpenSolaris release, special worth is attached to a stable release. About a web interface bugs can be reported and bug fixes followed up. JDS can alternatively be used as GUI. 

Solaris was certified with Trusted Extensions after Common Criteria in July 2008. Solaris 10 version 11/06 for the platforms x86/64 and SPARC reached the certification in Common Criteria EAL4+. For the first time the graphical user interface Gnome was also audited.
