Confused about OCA, OCP & OCM (Need some clarifications)

I want to do Oracle Certification.
I have following queries and would appreciate, if someone can answer me in detail.
1. Do I need to pass OCA first and then only I can appear for OCP? Cann't I directly just pass OCP exams and become OCP?
2. For OCP, I have read
TRAINING
Complete one of the approved instructor-led online or in-class courses.

EXAM
Oracle Database 11g: Administration II
1Z0-053 FORM
+
Submit the Hands On Course Requirement Form
What is approved instructor-led online or in-class courses? Do I need to pay something for this? what is the duration? In lay-man terms what exactly it is? Is there any alternative of this? It is too confusing on the oracle website.
Then again "Submit the Hands On Course Requirement Form " ...why it is too complex to get Oracle Certification?
I would say, Oracle should have something on their website, where it will ask, what course you want to do and generate one PDF file with the steps need to be performed/complete for the certification preparation/completion. Information is too scattered on oracle website.
I would appreciate, if one can tell me step by step, what needs to be done to be OCP.
Thanks in Advance,

Then again "Submit the Hands On Course Requirement Form " ...why it is too complex to get Oracle Certification?The Hands On Course Requirement Form is a tool for certification candidates to submit their required training details for verification. This form is required in order to obtain most Oracle Certified Professional and Oracle Certified Master certifications as well as some Expert Program certifications. Submitting the Hands On Course Requirement Form will accomplish two tasks related to your certification:
- It will trigger a request for Oracle to verify your attendance in an approved hands-on Course.
- After your attendance has been verified by Oracle, the form will generate a permanent record in Oracle's and Prometric's certification databases, showing that you have met the requirement. The record will become part of your personal certification history, identifiable as "Oracle Certified Professional Hands On Course Requirement".

Need some clarification on Replacement Path with Variable

Hello Experts,
Need some clarification on Replacement Path with Variable.
We have 2 options with replacement path for characteristic variables i.e.
1) Replace with query
2) Replace with variable.
Now, when we use "Replace with variable" we give the variable name. Then we get a list for "Replace with" as follows:
1) Key
2) External Characteristic Value Key
3)Label
4)Attribute value.
I need detailed explanation for the above mentioned 4 options with scenarios.

Just needed some clarification regarding the Viewer Builder and actually publishing your App...

If someone could let me know if my understanding is correct, that'd be a huge help... So I've designed my publication in InDesign and exported the .zip file from the Folio Producer. I've created all of my certificates/splash screens/icons. Lastly, I just recently went through the steps of the Viewer Builder. I'm now at the stage of this process that requires me to purchase the $395 single edition so that I can enter the serial number in the last stage of the Viewer Builder. Now, to my knowledge, once I get the serial number, Viewer Builder will then give me access to an .ipa file and a .zip file. The .ipa file is for me to test on my iPad, and the .zip would be used to distribute to the App Store. I guess this is where I get confused... Let's say after I test the .ipa on my iPad, I don't like some part of my publication. I know how to update my own documents obviously, and I understand that I would have to export another .zip file from the Folio Producer, in turn requiring me to edit the exported folio link in the Viewer Builder. If I had to do that, would I need to purchase another single edition serial number since the original App was edited? Or would the same serial number apply since I'm editing that same App in the Viewer Builder? My next question is somewhat similar. Let's say all of the information is up to date and I go ahead and publish the App to the App Store. However, maybe a month later or some time in the future, I needed to update a phone number or email address--some little detail like that. Again, I understand that I'd have to update the export link in the Viewer Builder, but would I then need to create a new app since my app was already published? Would I then have to purchase another $395 single edition serial number just so that I can update my information? This seems to be the only thing in this whole process that I could use some clarification on so that I don't run into any surprises in the future. Any help would be great, thanks!

Hi Joshua,
When you have purchased the serial, you can rebuild your app with your updated content, as long as you use the same bundleID (applicationID), that is tied to your Apple mobile provisioning profile. The serial number is valid for a one year period.
After you have submitted your app to Apple and it has been approved, please read: http://forums.adobe.com/message/4172167#4172167

PSE 7 confusion about folder location, help needed

Here's some background: I'm using PhotoShop Elements 7 on Win XP. I have an external firewire hard drive I use for overflow/backups. Originally, this showed up as a K: drive on my system.
I added a RAID controller and two more drives to stripe as a single drive for temp space rendering movies. This ended up as a K: drive and the external moved to L: However, when I did this there were some pictures from my catalog that I had on the external drive. I have used File > reconnect missing files to handle the moves, but PSE is still confused (very).
PSE has started to mix up the RAID (K:) and external (L:) content. If I move a set of pictures (e.g. a folder of them) onto the external drive (L:) via drag and drop in the folder location view, the folder will show up empty on the L: heirarchy, but will show up as a gray folder icon in the K: RAID drive hierarchy. If I open up windows explorer, the RAID drive will appear empty. In other cases (I'm not sure when/how yet), pictures physically end up on the RAID drive itself instead of the external. I have uninstalled both the external drive and the RAID drive and reinstalled them both, but they are still getting confused in the folder view by PSE. I've also tried moving content outside of PSE and just reconnecting missing files, but it still wants to put things under the K: RAID drive instead of the external L:.
I've searched everywhere I can think of for a description of what gray folder icons in the folder location view means and can find none. I'm not sure how to convince PSE that there's nothing on the RAID K: drive and it shouldn't try to connect the two. Any suggestions?
Thanks,
Jim

Thank you! I ran psedbtool and the output shows the catalog has the wrong drive letter for the L: drive.
Is there a way to make PSE forget about the K: and L: drives that it is so confused about so that it can relearn of their existence? If I use the drive letter reassignment to fix PSE, it will break other apps that are now dependent on the current drive letter assignments. I've tried removing all files from the L: drive, but it's still remembered as part of the catalog.
Thanks,
Jim

HD Workflow - Need Some Clarification Please

Apologies for asking another question so soon, but I need some help with my import/export workflow please.
So I've just upgraded to AE CS4 from 6.5 Pro.
I'm doing a show where I'm using XDCAM EX footage with cgi shots and elements, all comped in AE. The shots will be handed to the editor, who uses FCP, as Quicktime files, I think. This is where I need some help.
I have read and re-read (several times) the 'Color Management Workflow in Adobe After Effects CS4' pdf, specifically the 'High Definition Video Workflow' section. I am using a calibrated monitor (regularly calibrated and checked with a Spyder 3 Elite).
I get setting up the AE project to be colour managed to the HDTV (Rec. 709) working space, and I likewise understand using Interpret Footage to colour manage assets that are imported.
Where I'm falling down is outputting the finished shots to QT movies, specifically on two points: the apparent gamma of the output (as I see it in the QT Player), and the data-rate.
I understand setting the output to have the same profile in the Output Module of the Render Queue. But from there I'm stumped, because the QT outputs don't visually match the AE comp, with almost any codec I try. I understand there are QT codec issues when outputting from AE - I was reading about those the other day when I was hitting the same problem in AE 6.5. When I open the QT movie on the desktop (Windows XP Pro) it's invariably alot lighter, lower contrast. Along with the other issue that the data-rate of the QT output from AE is anything up to 8 times greater than I need.
I tried rendering Animation and PNG movies from AE, then feeding those through the Media Encoder, outputting via H.264 to get an MP4 with the data-rate around 50mbits/sec. That works on that, but again the movie is pretty washed out and low contrast.
I guess this is pretty fundamental stuff, but I've hit a brick wall over what to do. I'd appreciate any advice on the workflow to output the finished comps to hand to the editor, as a movie file, QT or whatever. And obviously knowing that what I see in my AE comp is what he will see on his FCP suite.
Julian.

Thanks for the additional comments and ideas.
In terms of profile, as I mentioned, the intermediates will be going off to the editor (off-site) for editing on his FCP suite. I'll stick to working in the prescribed HDTV (Rec. 709) space, and I've given him all the detail I can of how I'm working, but crucially I haven't stood at his edit-suite to see how the stuff looks.
But, he's no newbie, so I'm hoping it'll be OK.
Blasted shame about the H.264 BluRay not being compatible with QT - I thought I had this whole issue beat until that came along. It's not a matter of disk space here, but the editor is mithering that the intermediates we are testing, in either PNG, or Animation, and a couple of others, are choking his playback.
I'm not sure what to say about that, other than to go down this road of trying to squish these intermediates as low as possible without wrecking the look, hence finding that the DNxHD is providing the best solution. If it had been a SD project, I might well have tried the native H.264, even over our normal PNG workflow.
So what will play the native H.264 BluRay compressed output?
Julian.

Inquiry about OCA & OCP

Dear All,
I wish if i know how i can take OCA and OCP as Developer,
i wanna know if i must have Hand-on-course to have OCA and OCP as Developer
or not,and what about the original matireal
i wanna if any body know every thing about that subject,like he was taking this certification

user592551> i wanna know if i must have Hand-on-course to have OCA and OCP as Developer or not
Can you imagine being a Developer without any hands-on experience? I certainly wouldn't hire you if that was the case.hmm...question was regarding "Hands-on-course" not "hands-on experience".
user592551,
Although some OCP tracks may require instructor led traing (ILT) class(es) the OCP Developer does not require any ILT although there are "suggested" ILT classes. Even if you take them, entire syllabus may not be covered in those classes.

Hi frnds, need some clarification on OBIEE.

How the details of the reports created in OBIEE gets saved? Database or FlatFile. I have created some reports in OBIEE but not able to find the structure of the report or data stored in table in the database. Kindly help in figuring out this. Thanks in advance. Have a nice day.

Details of the report get stored in the Web catalog and web catalog reside on the Weblogic Server.If you want to store report details like Logical Query,Creation Time,Creation Date....etc then you need to enable Usage Tracking,Where this information will store in the database,If you want to export you can do that into a flat file,
Do let me know if you need any support in enabling usage tracking.
Mark if helps,
Thanks,

Checked FAQ: Question about importing into library, need some assistance.

Hi,
I've done some searching and have yet find my answer. I hope that some of the sharpshooters here can help out.
I keep all of my music on a network drive to avoid "bloating" my Mac with music. So the other day, I wanted to use iTunes to catalog what was on there and to load some more music onto my 'Pod. So, I performed an import of the library. Here's my dopey question: When one imports into a library, does all of the music come over with it, or, does just the songs' data get imported and then point to the source drive? Does this make sense?
TIA,
Chris

I also keep my music and all on an external drive. Before you catalog it you need to do one important thing or it will copy everything to your computer. Go into the Advanced setting under Preferences and uncheck *Copy music to your iTunes Music folder when adding to library*. If you don't do this you will end up with your music trying to be put on your computers drive. You can then use this to update your iPod as it points to the original file and will bring anything needed to load on your iPod.

Confused with all the software, need some opinions...

Hi, I am a recent Mac owner who is slowly trying to figure things out (I am bad with computers anyways) My dilemmas are: I was considering purchasing Office for Mac but then I see that there is also VPC so if I purchase VPC and download my Office for Windows on it, then I probably do not need Office for Mac. On the other hand I have read that VPC is pretty slow. The pricing of VPC is also a concern. I have researched few sites with similar programs like VPC that are cheaper and run pretty much like VPC (anyone heard or tryed IEMULATOR? www.iemulator.com, which is $25 , or guestPC www.lismoresystems.com, which is $50). The other thing is that i saw these sites about software that reads PC Cds on Mac (cdeverywhere.com and is about $40), and softarch.com/us/products/dm./html , which is about $60). So my question is if I have one of those virtual pcs or iemultor or whatever pc on my mac then i would not need those other PC reading software, coorrect?
All I need is to be able to exchange my files from my ibook to my pc desktop and viceversa with the easiest and cheapest software i can get. Anyone who has tried one of these mentioned above, I would appreciate your opinion on your experience with it. I like my ibook so far and all I am trying to do is to get the most use out of it.
Thank you in advance!

All I need is to be able to exchange my files from my
ibook to my pc desktop and viceversa with the easiest
and cheapest software i can get.
The cheapest way (ie free) is to use NeoOffice.
http://www.neooffice.org/
This is a fully compatible and functional office suite for the Mac, it is also free.
It can open and save Word, PowerPoint and Excel files.
Hi, I am a recent Mac owner who is slowly trying to
figure things out (I am bad with computers anyways)
My dilemmas are: I was considering purchasing Office
for Mac
This will also do the job as well and will be faster than using any emulated version of Windows.
but then I see that there is also VPC so if
I purchase VPC and download my Office for Windows on
it, then I probably do not need Office for Mac.
You would need to delete Office from your PC though, or purchase an additional licence in which case the Mac version would be better (and cheaper than buying VPC and another Office licence).
On
the other hand I have read that VPC is pretty slow.
It can be, and the native mac version of Office is faster than running Office on VPC.
The pricing of VPC is also a concern. I have
researched few sites with similar programs like VPC
that are cheaper and run pretty much like VPC (anyone
heard or tryed IEMULATOR? www.iemulator.com, which is
$25 , or guestPC www.lismoresystems.com, which is
$50).
Remember these do not include a licence for Windows which would be an additional cost.
The consensus about these products is that they do work, but are slower than VPC.
So my question is if I have one of those
virtual pcs or iemultor or whatever pc on my mac then
i would not need those other PC reading software,
coorrect?
Macs can read and open compatible PC files without the need for third party software. If you have Mac Office (or NeoOffice) they can both open Office files created on a PC.

Need some clarification please

Aloha all. I've been searching these forums, and the support pages, buy can't seem to get the info needed.Even though it seems like a no-brainer. I have the original iPhone, but am up to date system wise. My question is, is it possible to save sms/text messages? If so an explanation of how to go about it would be very much appreciated. Mahalo for any tips, info. JB

Never mind, figured it out.

How to rectify the error in this program.
3)     In this program I want to ask is there any way that I can be able to see the write statement output which is there in the initialization event block. If yes then how .
(Note I dont want to remove the paramter (selection screen) statement.)
Listing 18.13 Explain the Sequence of Events That Occurs in this Program
report ztx1813 no standard page heading.

write: / 'in Start-Of-Selection',
         / 'p1 =', p1.
top-of-page.
   add 1 to ctr.
   write: / 'Top of page, flag =', flag, 'ctr =', ctr.
   uline.
4) can anybody please mail me some exercise program queries ( right from the basic to complex one) on this mail id [email protected] or else u can give me the url of the website which contains such program.
EARGERLY WAITING FOR UR REPLIES

maqsood

Maqsood,
I had tested all your programs and I am getting the correct output. I didnt get any error message and I didnt do any changes. I just copied your code and executed it.
To your Q3, I can say...INITIALIZATION is used only to assign values to variables. It is not used for output.
Only the start-of-selection and top-of-page will be printed.

Need some clarification in WSDL based Proxy & Business Services

Hi,
Whenever we configure a Proxy service or Business service based on a WSDL, we use to select Port option instead of Binding when selecting our WSDL for the proxy/business service. Now my ques is why we go for a port instead of binding? what is the difference between them?
My ques may seem very basic but i have this doubt for long time so i am postin this.
Thanks,
Arun

Hi Arun,
In my opinion that is not such a big deal, and in most of the cases you can choose any of the options...
I usually prefer port because it keeps the service name... If you are proxying someone else's service it is better to keep it in a way that the service consumer doesn't notice the difference...
I'm guessing there are cases out there where the service consumer client requires that the binding operations be unchanged... But I've never came across with one of them...
Hope that clarifies...
Cheers,
Vlad

Partitioning in Oracle -- Need some clarification

Hello all,
While I was reading the document (PDF) on Oracle9i Data Warehousing Guide (Part No: Part No. A90237-01), I found one statement which made me confused.
The statement is regarding Hash Partitioning:
"Hash partitioning is a good and easy-to-use alternative
to range partitioning when data is not historical and there is no obvious column or column list where logical range partition pruning can be advantageous."
Can anyone suggest me, does this means that Hash Partitioning is not recommended for Data Warehouse type (DSS) applications? If yes, then I will be glad to know Why they are not recomended?
I would also like to know the practical differences between Range Partition and Hash Partition.

There are three types of partitioned tables in Oracle 8i: Range, Hash and
Composite. Range partitioning requires that rows identified by a "partition key"
fall into a predefined range of values. The value of a columns' "partition key"
determines the partition to which a row belongs.
A hash-partitioned table's rows have their physical location determined by
applying a hash value to the partition key column, providing for deterministic,
but well distributed physical data spread.
A composite-partitioned table has a two-part partition key, the leftmost being
a range-partition key and the rightmost being a hash partition key.
Composite-partitioned tables make use of subpartitions for their hashed
components. A composite-partitioned table consists of a set of
range-partitions, which are each composed of hashed-partitions.
Oracle9i adds a new partitioning model called list partitioning to the
set of partition methods already being supported in the Oracle RDBMS.
The new List method allows explicit control over how rows map to partitions,
by allowing to specify a list of discrete values for the partitioning column
in the description of each partition. One should use list partitioning
when you want to specifically map rows to partitions based on discrete values.
Hash partitioning is best used when the data does not easily lend itself to range
partitioning, but you would like to partition for performance reasons. Hash
partitioning evenly distributes data across a specified number of partitions.
Rows are mapped into partitions based on a hash value of the partitioning key.
When creating hash partitions, you must specify the method as "HASH", the
partitioning column(s) in the HASH, and the number of partitions or individual
partition descriptions.

IDOCs Packaging ? Need some clarification ;-)

Team,
Simple scenario:
=> JMS (xml) --> ( XI ) --> (IDOCs) --> SAP ECC.
This is scenario working fine.
However, If we have 10 IDOC, we have 10 LUW on the backend system (not good for the performance).
To avoid these multiple luw, we are using the IDOC packaging approach (no ccBPM) the wizard (idxpw).
So
1) XML messages are coming in XI
2) Since we have a filter (sxmsfilter), messages are kept aside for a while
3) Until a job (created using idxpw) wake up and start processing the messages
Our questions:
When does the packaging trick arrive ? We do not see the messages in IDXP (with the package icon), but with the yellow dot
thank for you help
MO A+

Hi XI Team,
Have a look at Sravya's blog
/people/sravya.talanki2/blog/2005/12/09/xiidoc-message-packages
Usually IDOC packaging is created at the sender side as explained in the blog. Have never tried IDOC packaging at receiver end.
In our case, we changed the IDOC XSD to unlimited and used it. It will create a single message in XI.
But in R/3 it is not an IDOC package. It will be a collection of IDOC. Each will trigger a new LUW.
Hope the weblog will give you some idea. If you are able to create an IDOC package at th R/3 do update us. I will give this scenario a try tomo. It is 12:20AM my time
Good Luck
Regards,
Jaishankar
