Why Is The Course Requirement So Strict?

Filed under: 1Z0-048, 1Z0-052, 1z0-007, 1z0-242 — Tags: — admin @ 11:03 am

Do You Give Exceptions? When the course requirement was initially implemented, only those courses related specifically to the exams in the track were awarded credit towards the requirement. As part of an ongoing analysis, we were able to expand the policy to include additional advanced courses related to the certification being pursued, thus opening the range of training options to meet the varied needs of our many candidates. Now the option exists to choose from a variety of courses to help increase knowledge while meeting the certification requirements. Our goal is to help candidates improve their skills, recognition and careers, and we feel that this is an excellent way to support our candidates. Because of our commitment to this valuable process, we do not provide exceptions to the hands-on course requirement for Oracle certification. Summary Oracle raised the bar for certification with the hands-on course requirement. This has had a clear and definite positive impact on the overall value of the Oracle certification – both for those who hold them, as well as those in the marketplace for Oracle credentialed individuals. As can be expected, we often get input from critics of the course requirement. Although in evaluating their position I often see compelling arguments, but sadly there is often also a clear bias.

For example, we’ve recently gotten negative feedback from a non-Oracle training center whose courses do not count towards our requirement. The primary goal of our program is for the candidates who earn our credentials to be experienced, well-trained and highly skilled. We believe that the hands-on course requirement supports that goal.

What is Oracle RAC ?

Filed under: 1Z0-048 — Tags: — admin @ 10:26 pm

Oracle RAC is a shared database environment where multiple server nodes share DBMS instances, with shared concurrent access to disk. In November 2003, Gartner analyzed usage and implementation of early adopters of Oracle Database 9i (9i) RAC. At that time, RAC was reliable and provided increased scalability and availability; however, it was complex and required highly experienced database administrators (DBAs) to generate value; the complexity was a RAC inhibitor.

Fast-forward five years and multiple releases: Oracle has significantly improved RAC’s operational manageability and reduced its skill level for implementation and management. We interviewed more than a dozen RAC customers (most of whom implemented Oracle Database 10gR2 RAC) to gain an understanding of the business value of implementing RAC, and its pros and cons. Overall, we found significant value that justified the additional software costs.

However, RAC is not for every application. Here, we provide an analysis of benefits, strengths and challenges, along with guidance on when to use or not to use RAC.

By year-end 2003, Oracle had approximately 1,000 RAC production customers; today, it has more than 15,000, bringing RAC to the mainstream. Oracle has penetrated the midmarket as well, primarily through its Dell reseller agreement. Thus, Oracle’s investment in Oracle Database 10g (10g) manageability has reduced the complexity inhibitor. RAC runs on all Oracle-supported platforms, with Linux being its platform of choice. Approximately 30% of RAC implementations have deployed on Linux (and the percent is rising).

Oracle’s main RAC sales theme is selling a fully integrated software stack, including the operating system (OS) — Oracle Enterprise Linux, which is Oracle’s distribution of Red Hat Linux. While RAC licenses incur a 50% increment over a single-instance DBMS (see www.oracle.com/corporate/pricing/technology-price-list.pdf ), Oracle justifies the pricing due to reduced hardware costs (in addition to RAC benefits).
