1Z0-052. Two big cert guides and official documentation - why so many contradictions ?

In this discussion i will compare two 1Z0-052 prepare certification guides (one of these is marked as "Oracle Press" !!!) and official Oracle Database 11g Release 2 (11.2) documentation (the exam "1Z0-052" has been validated against this documentation) in effort to understand why these sources have so many contradictions (direct and undirect).
Begin with this one :
1) "(Oracle Press) John Watson - OCA Oracle Database 11g: Administration I Exam Guide (Exam 1Z0-052)", "Chapter 2: Exploring the Database Architecture", page 54 :
"Note that from release 8i onward, checkpoints do NOT occur on log switch..."
2) "Oracle Database Concepts 11g Release 2 (11.2) Part Number E25789-01", "13 Oracle Database Instance", "When Oracle Database Initiates Checkpoints" :
Thread checkpoints OCCUR in the following situations:
- Consistent database shutdown
- ALTER SYSTEM CHECKPOINT statement
- Online redo log switch
3) "Biju Thomas - Oracle Database 11g Administrator Certified Associate study guide", "Chapter 8 Introducing Oracle Database 11g Components and Architecture", page 413 :
"Checkpoints OCCUR automatically when an online redo log file is full (a log switch happens)."
My question is :
Does checkpoint occur or not on log switch ?
Many other contradiction follows....

Hi John,
it will be my sixth certification in the last 3 years (i have all major certifications in Java)... But it is the first time i see that the Official Documentation of the product doesn't reflect completely the Certification Preparation Guide (i'm not going to say that you book is wrong, i'm about the complete compliance).
I cannot place my questions in another oracle DBA forum, because there most frequently the responses are "If you see the Official Documentation you find that..." and now i know that Official Documentation sometimes mismatch for the exam.
You (and I) certainly know that the certification exam is the multiple-choice questions... If i will find the question :
When checkpoints occurs (select all valid questions) ?
1) Consistent database shutdown
2) Issue of "ALTER SYSTEM CHECKPOINT" statement
5) Online redo log switch
after your explanation (see your first reply) now i know what can i must check and what i must not check, but before your explanation with small knowledges of database how can i be shure that your information is correct if the Official Documentation says the contrary ?
If i will find the question :
What is the checkpoint position ?
1) is the SCN (the System Change Number) in the redo stream where instance recovery must begin
2) ...
3) ...
If read only your book i cannot see SCN, i see RBA. How can i know that SCN and RBA are the same think if neither Oracle Documentation neither your book say that ? What another sources or guides i must have ?
And what about the location of the "alert_SID.log" file ?
What you suggest me about this exam question :
Which initialization parameter determines the location of the alert log file?
1) DIAGNOSTIC_DEST
2) BACKGROUND_DUMP_DEST
3) ALERT_LOG_DEST
4) USER_DUMP_DEST
If i read you book i select "BACKGROUND_DUMP_DEST", because in your book i see :
"The alert log is a continuous record of critical operations applied to the instance and the database. Its location is determined by the instance parameter BACKGROUND_DUMP_DEST, and its name is alert_SID.log, where SID is the name of the instance.... The directory ADR_HOME/trace (ADR is automatic diagnostic repository) is used as the default value for the instance parameters USER_DUMP_DEST (trace files generated by user sessions) and BACKGROUND_DUMP_DEST (the alert log and trace files generated by background processes)."
But if i read Official Oracle documentation i select "DIAGNOSTIC_DEST", because i see :
"The parameter BACKGROUND_DUMP_DEST is ignored by the new diagnosability infrastructure introduced in Oracle Database 11g Release 1 (11.1), which places trace and core files in a location controlled by the DIAGNOSTIC_DEST initialization parameter."
Therefore if i read you book i select "B", if i read documentation i select "A".
You must understand me - the only my goal is to be maximum precise - this precision is required for exam. I also have not free time to waste - during the week i'm working, i'm preparing for this OCA DBA certification, during weekend i'm writing my book in mathematics for preschool childs (it's also about 700 pages)...
Excuse me and thank you,
Dmitri.

Is it possible to combine two existing iTune accounts and then cancelling one? Many thanks.

I am trying to combine two accounts that I have on iTunes (created separately over the years) so as to then delete/cancel one to only have one active account (with all of my combined purchases, etc. on this combined account).
Is this possible, or is there another way of transfering purchases to one of the accounts and then just deleting the then "empty" one?
Thanks for any advice / input

Differences between 1Z0-042, 1Z0-043 1Z0-052 and 1Z0-053 and 11g OCP

Hi All
I have a small dilemma
For Christmas I was given a copy of OCA/OCP Oracle Database 11g All-in-One Exam Guide with CD-ROM: Exams 1Z0-051, 1Z0-052, 1Z0-053 (Osborne Oracle Press Series) [http://www.amazon.co.uk/Oracle-Database-All-Guide-CD-ROM/dp/0071629181/ref=sr_1_5?ie=UTF8&s=books&qid=1262090730&sr=1-5|http://www.amazon.co.uk/Oracle-Database-All-Guide-CD-ROM/dp/0071629181/ref=sr_1_5?ie=UTF8&s=books&qid=1262090730&sr=1-5]
As you will see in the book title it covers 1Z0-051, 1Z0-052 and 1Z0-053
About a year ago I attended the following courses
TT - Oracle D/B 10g Program PL/SQL-QA-IQ
TT - Oracle PL/SQL - GK
TT - Oracle 10g Intro to SQL
I have been meaning to get round to taking my exams and OCA qualification is no problem as I can take 1Z0-051 and 1Z0-052 using the above book and the knowledge I gained on the course (even though the course was 10g).
But my question surrounds 11g OCP and how it requires instructor led training - now I have done my 10g course but I guess this wont count as an instructor led course for 11g OCP.
If not then im going to need to take the route of 1Z0-042, 1Z0-043 to get OCP and 1Z0-050 to upgrade to 11g
So I would ask how safe I would be learning the above mentioned book and taking the 1Z0-042, 1Z0-043 exams. I understand there is no accurate answer as it is subjective but if 1Z0-052 and 1Z0-053 (11g) knowledge covers 1Z0-042 and 1Z0-043 (10g) knowledge then there should be no problem, right?
I really dont want to have to take the book back or purchase another.
Thanks in advance

RobYour'e thinking sensibly about this. Well done. And the hands on course needs to be considered carefully and I often say this can be deciding factor in planning.
IMHO there is at least 80% commonality between the topics for 1z0-042 AND 1Z0-052 .... and probably similar for 1z0-043 and 1z0-053 whoug I've never directly checked this and there may be a greater divergence there.
Be aware some topics in 1z0-050 will not be covered in the books you have as far as I am aware.
One option you have not considered is taking exams in this order ..... this will give you 10g OCP and 11g OCP. This is wha I did .... but it mainly occured that for me way as the 1z0-053 was fairly delayed into production and I wanted the certificates I could have as soon as possilble .... ie 10gDBAOCP and 11gDBAOCA. I actually did the 1z1-053 beta for my 11g DBA OCP ... cheaper than 1z0-050 as I already had 11g DBA OCA.
1z0-051 1z0-042 1z0-052 1z0-043 1z0-053.
I know you dont want to buy another book, but the 10g ones from Sybex (and associated CDROM's) give a slightly different viewpoint (though they are for 10gR1 and are not updated for 10gR2 topics). IMHO the sybex books can ometimes go a little over the top in some areas. But all these books can contain some errors ... however they do provide an extra set of practice questions. However it is an option for you.
Its worth registering your 10g course as a hands on course as soon as reasonably possible to ensure there are no issues with it (I assume you have attended the course from Oracle University).
Anyway these are my thoughts. But you know your own circumstances and are responsible for your own decisions. Good Luck.

Training for 1z0-052???

hi everybody, for the below mentioned exam, candidates are not expected to undergo any course.
1Z0-001 Introduction to Oracle: SQL® and PL/SQL™
But, is that mandatory to undergo the course provided by oracle for the exam
Oracle Database 11g: Administration I 1Z0-052 ???????
In this case it is not possible for me to complete the course provided by oracle..
will i be provided a certificate for the below exam
1Z0-001 Introduction to Oracle: SQL® and PL/SQL™, even though i did not 1z0-052???
please clarify. thanks...

but in the page,
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=41&p_exam_id=1Z0_052
they have given the details for the exam 1Z0-052, in which --------------------------------------------------------------------------------
Recommended Training and Preparation
Oracle Database 11g: Administration I is mentioned. looking at that link i found that candidates are required to take a course from oracle.It is recommended, NOT a must.
so, from your answer i could infer that for 1z0-001 and 1z0-052 for being an OCA, candidates are not expected to undergo the training sessions from oracle. am i right??? Correct.

Relation between different GUID and tables in RPM

Hi All,
can you tell me the relation between different GUID and tables in RPM. Many thanks.

Hi Deepesh,
Try the foll. join :
    SELECT fragment_guid INTO (some internal Table)
         FROM comm_pr_frg_rod

Certview Question, and 1Z0-052 Question

Hello All,
I recently passed 1Z0-051. Very pleased with that. I have been reading Oracle press book for almost 1 year, and preparing for 1Z0-052 for almost 1 year. I have 1 year experience of Oracle database experience, integrating it with coldfusion for web design.
1st issue) I have logged into certview previously succesfully a few days ago. Tried today, and it wanted me to "authorize" a second time, my creds from the pearsonvue website, which I did, exactly as name/email/city are listed on pearsonvues website. So I put the information in,,1,,2,,,3 times, locked me out, and everything was matched up correctly.
Why did it ask me a second time for authorization, when I linked the account/creds two days ago?
2nd issue) Any last minute tips before attempting the 1Z0-052? I have been using 11G at home for a year installed on linux.
$195 is quite a bit, so hence the reason I want good results.

Why did it ask me a second time for authorization, when I linked the account/creds two days ago? One possibility is that you were using different Oracle SSO's .... some have used one for work and one for home.
Another is that Certview was in a maintenance period.
A third is that Certview has a mind of its own and will do this from time to time.

$195 is quite a bit, so hence the reason I want good results.The Oracle Press book practice questions / tests should give you a good idea of the standard you're at providing you haven't used them over repeatedly and have meorised the questions. (In which case buy the sybex book or get SelftestSoftware practice tests). But I think there comes a point where one has to take the exam.
Other than that use normal test preparation good practice.
eg: Ensure you know where the Test Center is and plan to get there in good time and decide what you going to do if you get there early!!! ... etc. etc. Be aware you to plan your test and to be aware of how to handle questions that you dont know (eg marking them for review later etc).
There is also a possibility you may be able to grey out answers you wish to disocunt by right clicking on them ... read the intro pages to the exam carefully to see it this is available. this feature is not available on some simulators. It may or may not be present for your exam.
Chec kthe exam topics on the oracle website exam page to ensure they have not changed.

1z0-052 preparation and real practice...

Hello.
I have successfully passed SQL Fundamentals I exam recently and my new aim is Administration I. I purchased necessary 1z0-052 exam guide by John Watson, however without practice it is impossible to neither get skills nor pass exam. Will it be enough to try applying everything that is in a book on Oracle 11g XE that was published recently? There are different versions of Oracle 11g that are available for download but I am not really sure which is enough for preparation. Should I pay for those versions?
I kindly ask you to advise me the necessary applications, systems that could help me to get skills for both certification and real practice.

If you're trying to pass the DBA track exams, I would suggest downloading the enterprise edition of whatever version of the database you want to be certified on rather than using the express edition. The OTN license will generally allow you to prepare for certification exams (or any other self-study purposes) using the enterprise edition without purchasing a license.
The express edition does things a bit differently than the other editions from a DBA standpoint because it is designed to be used in an environment where there may not be a DBA. I wouldn't use the express edition to prepare for DBA certification exams.

Confused about calling translation profile explanation In official cert guide 640-461

Hi.
On page 143 of the official ccna voice cert guide there Is an example of a translation profile where calls from the PSTN with DID range of 6xxx should be converted to 5xxx to reach the internal network.There Is an explanation of why the called rule Is used instead of the calling:
"Assigning the translation rule as a calling translation would change the caller ID of a person
calling into the organization."
I don't understand this line. Shouldn't a calling translation change the caller ID of a person calling from within the organization and not into It ?

You are saying "Calling Translation" but do you mean to say "Calling Party Transformation?"
The Calling Party Transformation is relative to the direction of the call flow.
In CUCM, on a SIP trunk, in the direction of Inbound, the Calling Party is the PSTN caller calling into your organization.

How to center object between two guides (or one guide and edge of artboard)

Simple question: how can I center an object between two guides or between a guide and the edge of the artboard?

Chris,
You may (Smart Guides are your friends):
1) Create a rectangle between the two Guides or between the Guide and the Artboard edge, by ClickDragging with the Rectangle Tool from (the desired spot) on one to (the desired spot) on the other (Smart Guides say path/path or path/page when you are there);
2) Select both the rectangle from 1) and the object, then Click the rectangle again, then use the relevant options in the Align palette.
That should move your object to the centre in the direction(s) you choose.

Should get 1Z0-051 or 1Z0-052

Hi there,
i'm thinking to get OCA, which exam should i go first?
1Z0-051 or 1Z0-052. Please advice.
Thanks

Hi,
I would also recommend taking the SQL exam first. You can do it online. Just be sure do do at least some practice exams (for instance the Transcender exam preparation recommended by Oracle, try at least the demo) to get familiar with the form of questions.
I just passed the online SQL exam last weak and the proctored Administration exam today. You definitely need more knowledge for the Admin exam than for the SQL one.
However, for me the SQL exam was the harder one, because you have to be really focused on the questions, read every requirement carefully, examine an awful lot of exhibits, and do not overlook a tiny difference in the answers, like a missing quote here or a duplicate set clause there ... I felt really tired and I needed every second of the two hours limit.
On the other hand, I was very relaxed at the today's administration exam. I understood the questions clearly, had a plenty of time to mark the answers and I was quite confident with the answers.
If you have some practical experience, you should pass the cert exams test with ease. Good luck with your exams.

1z0-052 & 053 based on 11g or 11gR2

Hi guys,
I am preparing the exams 052 & 053 now. I heard that these two exams are updated to 11gR2. So I want to check this information here. If it is updated to R2, where can I get new materials; if not, when will it be updated?
Thanks

McGraw.Hill.Oracle.Database.11g.DBA.Handbook.Dec.2007In essence these should be perfectly acceptable for the exam topics.
When the exam is validated against 11gR2 it is essentaily a check that the exam answers have not changed by any changes with 11gR2.
However one should always check the exam topics covered by these books have not changed by checking agsinst the topics on the exam web page ... remember these books are often prepared when the exam is in beta and it is unlikely there is an update with the production release.
I believe the mid-life update of the 1z0-042/3 exams for 10gR2 from 10gR1 were slightly more eextensive, however agin the important thing was to check out the exam topic changes. In essence the changes were more to track changes in Oracle Training courses that directly to do with changes in nthe Oracle Versions.
It is of course however useful to persue over the 'new and chaged features' of the 11gR2 release, it is a useful exercise for you to locate these yourself anyway.

OCA - 1Z0-052

Hello guys,
I'm having the 1Z0-052 (11g Administration I) exam on monday to have my OCA certification. I already succeded the 1Z0-051 (11g SQL fundamentals) and 1Z0-047 (SQL Expert) and now I'm trying the 1Z0-052.
I read [this book|http://www.amazon.com/Oracle-Database-Administration-Guide-1Z0-052/dp/0071591028] and I find the content quite easy. I also managed to do/answer to all the lab questions without any solution. I have the feeling that it's a lot more easier than the SQL Expert and some of its content is more detailled in the 2 previous exams I took. For example, managing constraints, indexes, temporary and external tables, dealing with transactions, BFile datatypes... are more detailled in previous exams than this one.
Maybe the book is not complete? I checked with the [exam topics|http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=41&p_org_id=1001&lang=US&p_exam_id=1Z0_052] and the book covers them all. So I was wondering if anyone of you have some advice?

Thanks1z0-047 and 1z0-052 cover different topic areas. 1z0-047 is designed to ensure a very good knowledge of SQL techniques are known ... 1z0-052 is designed to ensure a solid grounding in theory and practice of database administration has been achieved. Both are 'easy' after you gain a solid knowledge of the material, though the level of SQL in 1z0-047 would scare some DBA's to death ... some would be DBA's on this forum seem to want to avoid SQL completely.
Sometimes the book is not enough, sometimes experience counts, and always be preapred to goto the Oracle Documentation as an authorative source. However you do seem to have practiced hard so hopefully it is enough.
Good luck on monday and hopefully it does not give any surprises.

About 1Z0-051 & 1Z0-052 11g

Is there a waiting period for taking the second part of the administrative certified associate exam 1Z0-052?
Should it be taken right away or immediately after 1Z0-052?

1Z0-052 isn't really the 'second' part of the certification. It is generally taken second, but that's not a requirement. The order you take the tests in is completely arbitrary. Most people take 051 first and 052 second, but that's not required. I talk about that in my blog here:
Oracle Certification Prep: What Order Should I take Oracle Certification Exams In?
That said, I'm going to have to disagree with John (something I don't do often). Unless you are really comfortable with the material for both exams, I would not recommend taking them both in one day. John is an extremely knowledgeable DBA and splitting his concentration between two exams is not a problem. For that matter, I originally became an Oracle OCP when I worked for Oracle's Support team. They had Prometric create a lab in the building where we worked for a day. Since they were only going to be there the one day, I took all four of the tests required at the time for the 7.3 certification -- two before lunch and two after. Again, though, I was very familiar with the information being tested.
If you are not 100% confident of your mastery of the material, I think that you will have a greater chance of success if the tests are separated by at least a day or two so that you can focus all of your concentration on one at a time. The overlap between 051 and 052 is not very significant and 052 is generally considered to be the more difficult of the two exams. It is more important that you take enough time preparing for it that you are comfortable with the information than taking it as soon as possible after passing 051.

1Z0-052 Administration I Exam (11gR2) - Oracle Press 11gR1

The pages on the Oracle Web site state that the exam is based on the 11gR2. I am not sure when this changed as I am sure I checked in Nov 10 and it was 11gR1. There is currently no Oracle Press material to cover the most recient release of the database. If I study from the Oracle Press OCA 11g Administration I Exam Guide (1Z0-052) by John Watson, am I on safe ground? 11gR2 has some very interesting new features. Will these be included? The exam subject detail doesn't really go down the required level.

I think you should be safe. I take it next month so I hope we are. :)
Heres a link to the site with the exam topics and it looks pretty much the same as before:
