Editor's Notes

• #3: Show of hands, how many people are certified? This will definitely help you on your way to getting certified. Can’t cover everything in 1 hour, talk about the slides, details are available online. We have a lot to cover, because of this I can’t spend too much time on each slide. Don’t worry, the presentation and handouts (lower level detail and examples) will be available on the website no need to spend time jotting down the details. If that’s a problem you can email me, and I’ll gladly send you a copy. I’ll touch on particular areas of each slide throughout the presentation. Appreciate if if you saved your questions until the end of the presentation. For those of you not interested in Certification, the second part will provide you with info related to some of the less known features of Oracle and a few tricks / concepts that you might find useful. NO WAY I CAN TEACH THE MATERIAL IN ONE HOUR, BUT I CAN PROVIDE YOU WITH INSIGHT, EXAMPLES, and CONCEPTS.
• #4: 1.         Practical experience (no substitute). 2.         What is OCP and how is it measured in the industry. With today’s economy you need any little edge you can get in landing the next contract or finding the next full-time job. OCP can’t hurt and can only help you in this market. Oracle Certification is Technet.oracle.com (article) http:// crn . channelsupersearch .com/news/CRN/30947.asp . Preparation is a great complement to practical experience. Worse case scenario, you learn a few new tricks / techniques. 3.         Looks good on your resume, helpful for employers who value certification, saves time during an interview, opens up a few more doors. Why you should get Oracle certification The demand for professionals in information technology (IT) is high and the competition for jobs is intense. Individuals, experienced or new to the profession, need to know what skills make them attractive to employers. Employers look for ways to distinguish employees and prospective employees that have the solid foundation of skills needed for effective performance. The Oracle Certified Professional (OCP) Program helps the IT industry make these distinctions by establishing a standard of competence in specific job roles. An Oracle Certification is a valuable, industry-recognized credential that signifies a proven level of knowledge and ability. Benefits to the Technical Professional The Oracle Certified Professional Program can give you a distinct advantage. An OCP Certification demonstrates that you have solid understanding of a job role and Oracle products used in that role. Being an Oracle Certified Professional can help raise your visibility and increase access to the industry’s most challenging opportunities. OCPs have testified to the value of Oracle Certification: 97% said they have benefited from certification 89% said they gained more confidence in their Oracle expertise after becoming certified 96% would recommend the program to a professional colleague* Benefits to the IT Employer The Oracle Certified Professional Program is also valuable to hiring managers who want to distinguish among candidates for critical IT positions. For companies that send employees through annual IT training, certification ensures a return on the training investment by validating the knowledge and understanding gained at training sessions. Companies can also combine certification with an employee development program to enhance employee loyalty and performance on the job. Hiring certified professionals has a direct impact on a company’s bottom line, as these conclusions from a research study by International Data Corporation** suggest: Certified Professionals handled 40% more support calls per person, per day than uncertified staff Companies that advocated certification reported 49% less down-time than those that did not For the majority of companies surveyed, the savings from increased effectiveness paid the costs of certification in less than nine months
• #5: The OCP (Oracle Certified Professional) program was developed by Oracle Corp and Sylvan Prometric in 1997 . Used to recognize technical professionals who can demonstrate the depth of knowledge and hands-on skills required to support Oracle's core products according to a standard of excellence established by Oracle Corp. Currently, Oracle has certification programs for DBAs (database administrators), application developers, and database operators (DBOs). Each OCP program is composed one to five exams. Each exam will challenge students to apply specific knowledge that you have gained through Oracle training, as well as experience they've developed on the job, to real-world scenarios. For each exam, students work on a computer with no other resources, and have up to 1.5 hours to answer a number of multiple-choice questions. Students are not required to take any Oracle training courses before attempting the certification exams ; however, Oracle Corp. suggests that students have completed up-to-date training in the specific job role and have at least six months of on-the-job experience. We have found that students with no on-the-job experience, but instead hands-on experience with the Oracle database server, in conjunction with our Oracle training , consistently pass the Oracle DBA certification exams.
• #9: Being Oracle certified gives you a competitive edge in the marketplace. As more and more companies are implementing Oracle databases, the demand for certified employees is becoming very high. Contractors sell narrow skill sets and must claim to be immediately productive. Someone with Several years experience and a current DBA certification looks like a good bet for many contractor positions.
• #16: Palm flash cards are great as if the Certification programs. Reuters has a training budget and an education budget (school…etc). Most companies have this. I’m able to leverage from both by taking Oracle University Classes AND Hofstra classes (separate budget, class contains Oracle student kit). Also nice to meet other Oracle DBA’s in the industry.
• #17: Call the prometrics phone number or go to www.2test.com Or register online. Make sure you schedule 2 days prior and cancel one day prior.
• #20: Show of hands, how many people are using Oracle 10g? Used in Production? Suggest taking 9i, more companies are using it and it’s easier to learn. Drawback to taking 8i as opposed to 9i. In some case you’ll need to unlearn some of the features of Oracle 8i, however, Oracle 9i emphasizes these differences Making it easy to remember. You can apply 1Z0-001 in place of 1Z0-007.
• #22: You need training that gives you hands-on experience with the database. Exams contain scenario-based questions that only practical experience with the database will enable you to answer. Oracle provides simulator CD’s to assist you with this task.   Suggest going through each question and marking one’s not sure of. Beware of Required vs Recommended. Example: Required – at least one control file Recommended – Three control files Required: Two Redo log groups Recommended: Three redo log groups Default values…..etc; Best answer, could contain multiple ones. Oracle’s best answer. Order of events
• #26:   Your certification doesn’t expire, only get’s outdated. Oracle suggests renewing your certification for each new release. Receive
• #27: Mention previous presentations and where This presentation will be presented (upcoming presentations and hopefully, NYOUG).
• #42:   8i / 9i method for suspending exports and imports. 8i / 9i method for restarting failed exports and imports at point of failure. Ctrl+c and stop_job, start_job, parallel, status,….etc; 8i / 9i method for controlling the number of threads/processes. Ctrl+c and parallel and parallel hint 8i / 9i method for direct mode imports. Automatic 8i / 9i method for monitoring export and import. DBA_DATAPUMP_JOBS, DBA_DATAPUMP_SESSIONS, DATAPUMP_PATHS -> joined with v$session 8i / 9i method for importing and exporting data via PL/SQL. DBMS_DATAPUMP 8i / 9i method for remapping tablespaces and datafiles Allows you to map objects to tablespaces other than the ones the objects were originally assigned to. Remap_datafile, remap_tablespace
• #43:   Exports aren’t too bad but imports are like watching paint dry. This will alleviate a lot of the pain in performing those nasty imports. I might even abandon my TTS solution and revisit export and imports…….A.K.A Data Pump (export and import on steroids). Exclude and Include keywords are great when you want to export or import a large percentage of tables. Using the exclude keyword via par file requires less coding and room for error. There wasn’t a way to export/import just procedures and functions. You needed to finagle your export/import scripts or recreate the procedures from the DDL. Ability to suspend and resume an export/import job at will Ability to restart failed jobs from the point of failure Support for direct mode imports.
• #44:   It’s a no-brainer Pre configuration steps =================== Create directory pump_dir as ‘ /……..’; Grant read on directory pump_dir to scott; Export Command =============== oracle@testserver-test1>expdp hh/xxxxx dumpfile=pump_dir:test_tbs_full_db.dmp logfile=pump_dir:test_tbs_full_db.log Import Command =============== oracle@testserver-test2>impdp hh/xxxxx dumpfile=pump_dir:test_tbs_full_db.dmp schemas=devuser remap_tablespace=system:users
• #56: Segment shrink operations may change the ROWID of one or more rows of a table segment. Therefore, row movement on the segment must be enabled before the segment can be shrunk.
• #57: Segment shrink operations may change the ROWID of one or more rows of a table segment. Therefore, row movement on the segment must be enabled before the segment can be shrunk.
• #85: ASM requires an add’l instance and RAC or Non-RAC and volume manager and fault-tolerant – No need for datafile mgmt with OMF – only tablespace and adding files to disk device. UTL_MAIL The UTL_MAIL package provides a simple API to allow email to be sent from PL/SQL. In prior versions this was possible using the UTL_SMTP package, but this required knowledge of the SMTP protocol. The package is loaded by running the following scripts: CONN sys/password AS SYSDBA @$ORACLE_HOME/rdbms/admin/utlmail.sql @$ORACLE_HOME/rdbms/admin/prvtmail.plb In addition the SMTP_OUT_SERVER parameter must be set to identify the SMTP server: CONN sys/password AS SYSDBA ALTER SYSTEM SET smtp_out_server='smtp.domain.com' SCOPE=SPFILE; SHUTDOWN IMMEDIATE STARTUP With the configuration complete we can now send a mail using: BEGIN UTL_MAIL.send(sender => 'me@domain.com', recipients => 'person1@domain.com,person2@domain.com', cc => 'person3@domain.com', bcc => 'myboss@domain.com', subject => 'UTL_MAIL Test', message => 'If you get this message it worked!'); END; /
• #86: Pg 426  9i Merge statement – upsert statement gives you the ability to perform update and inserts to a table in a single SQL statement 10g expanded on this statement by providing you with the following enhancements The update and Insert clause is optional You can do conditional Update for a merge You can perform a conditional Insert using the where clause It has a new ON constant filter predicate to insert all rows to the target w/out joining source and target tables An optional DELETE clause can remove rows while performing updates.
• #87:   Scheduler is primarily made up of the following components: Program – Task to perform and its arguments (anonymous PL/SQL block, stored procedure or OS command/executable) DBMS_scheduler.create_program Schedule – When and how often a job will be executed Job – Specifies the Program and Schedule to be executed.
• #88: Pg 106 Calendaring Expressions ================  Job can have the following frequency: Yearly, monthly, weekly, daily, hourly, minutely, and secondly Interval = How often Specifier name = hours or days the job should be run on. ByMonth ByWeekNO ByYearday ByMonthDay ByDay ByHour ByMinute BySecond
• #90:   Regular Expressions are used for searching and manipulating complex patterns. Used by Unix Shell programmers/users to perform complex tasks. It’s now available in the RDBMS. The following four functions support regular expressions: REGEXP_LIKE REGEXP_INSTR REGEXP_REPLACE REGEXP_SUBSTR
