1Z0-117: Oracle Database 11g Release 2: SQL Tuning is one among the most recent Oracle certification exams currently available. This exam is a component of the Oracle Expert series, and spending it'll make the candidate an Oracle Certified Expert, Oracle Database 11g Release 2 SQL Tuning. the power to maximise the performance of SQL during a database is an incredibly valuable skill. Being acknowledged as an expert will provide a lift to the marketability of any Oracle professional. However, i will be able to note that I even have been taking Oracle certification exams for several years, and this test was probably the foremost difficult of any of them. this text is meant to supply some insight about what is going to be expected from you on the test to assist guide your preparation.
Your first stop in preparing for this or any Oracle certification test should be the exam topics page on the Oracle Education website. Every subject which will be covered within the 1Z0-117 exam are going to be listed there. The SQL Tuning Expert exam has forty-seven topics in eighteen broad categories. the foremost important of those are the following:
Interpreting Execution Plans
- Application Tracing
- Optimizer Operations, Statistics, and Hints
- Star Transformation
- Bind Variables
- SQL Tuning and SQL Access Advisors
- SQL Plan Management
- Parallel Processing
None of those topics is straightforward . Each of them contains enough details to permit Oracle Education to make questions that need candidates to possess a radical understanding of the topic so as to supply the right answer. Because this is often an OCE-level instead of an OCA or maybe an OCP-level exam, most of the questions would require in-depth knowledge of the topic .
On the SQL Tuning exam itself, there'll be 80 multiple-choice or multiple-answer questions with a deadline of 150 minutes and a passing score of 66 percent. the bulk of the questions within the exam I took were multiple-answer instead of multiple-choice. With multiple-answer questions, you'll need to pick the right two, or three, or maybe four answers instead of only one . Since Oracle certification exams don't have partial credit, multiple-answer questions will always increase the problem . Providing no answer to an issue counts against your score the maximum amount as answering one incorrectly, so you do not want to go away any questions blank -- albeit meaning simply picking a random answer. One bright spot of the 1Z0-117 exam is that the deadline is large and therefore the number of exhibits is fairly small as compared to others just like the SQL Expert exam. you'll (and should) take some time when reading the questions so you're clear what's being asked. make certain to seem carefully though all of the answers. Often you'll find a minimum of one with a clear flaw that rules it out as an accurate answer. Eliminating one or two of the answers during this fashion will allow you to concentrate your efforts on the remaining possibilities.
Like all of the Expert series, 1Z0-117 is meant to pass only those people that have a radical understanding of the topics covered by the exam. I definitely found this to be very challenging and that i think that it's one that's getting to fail a big number of the people that take it. If you are doing not want to be one among those, make certain to spend a sufficient amount of your time preparing. you ought to be comfortable with all forty-seven topics before scheduling the exam.
Good luck on the test.
