How much XML/Java does one have to know?

I'm new to OA and I have a question. Besides Oracle and PL/SQL how much XML/Jave does one need to know in order to pick up this product. Does it get in your way if you don't know either? Can you get by with out it?
In other words where is that knowledge inportant?

I think this thread has been discussed so many times on this forum, always search old threads before raising new! One need core java knowledge along with pl/sql to start with OAF.
You definately don't need knowledge of xml here as it is generated automatically by Jdeveloper. If you have some knowledge of j2ee design pattern , it would be an added advantage, but basic knowledge of core java is sufficient to start with OAF.

Maybe 5-10% better in my experience, but it is impossible to say what your results might be until you try it out in your home.

How can I tell what video card and how much video memory does my iMac have?

How or where can I find out: which video card does my iMac have and how much video memory does it have? I've tried looking in System profiler, but I did not see it there. Thank you.

Once you open System Profiler there should be a line called "memory" which is the RAM (vs. hard drive size which is not what is called memory), e.g., Memory: 1.5 GB
For video click on the line Graphics/Displays and look at the chipset line, e.g., Chipset Model: GeForce2 TwinView
Kappy's instructions are handy for checking the original configuration of your computer, but that may have been changed at some time, especially if you bought it secondhand.

I am considering buying a new MAC laptop to run LOGIC for composition and band live/recording, but which one is best as I do not want to spend too much money? Does it have a line in and how do you monitor sound? Will I need adaptors and a interface?

Can anybody help?

Also, I am guessing as Logic only runs on MAC surely then they would not the best spec to recommend to run it?
I see all the upgrades as additional memory or a faster process?
Is a retina screen necessary, and why flash based storage against a 1TB hard drive, and a i5 instead of an i7
The main reason for this purchase is to play live and use backing tracks and record found sounds and make creative songs.
I hope you can provide some valuable feedback, as I am a longtime MAC user and see upgrades and changes happen regularly but the most important thing is the songs not the equipment.
I have £500 already and willing to add another 500 to 700 pounds, then software extra.

HOW DOES ONE HAVE B.T. BROAD BAND & TELEPHONE !!

My argument starts with b.t. Broadband and phone, question how does one have broad band and phone if you have never ordered it in the first place, No modem means No broadband,No engineer,No Activation codes , No one has visited my home so No installation is this true !!. Yes I think so, can some one put my brain to rest.
Right I will start from the beginning back in November 2010 I called b.t. Sales and made an enquiry about getting broadband and a telephone package installed,so then this guy in sales said i would have to set a D/D up and he would have to do a credit check on me,but i told him their was a problem ,as i did not have enough money in my bank account to set another D/D up,he then informed me he would keep the enquiry active for seven days,after this time the enquiry would be scrapped,so i never thought anymore about it,then 2 months later b.t. have started billing me, the first bill was for £130.44 the next bill was for £223.31 & to cap all that they have now instructed a debt collection company to collect £365.98 within 7 days or else,i also asked b.t. what date did & time the instalation engineer had called to my home,and the date the package with the modem was delivered ,because you have to sign for this item i was told by the royal mail.
Then this Saturday 25/6/2011 a woman from b.t.residential telephoned me to apologise and the matter was now closed,and they were sorry for setting this account up in the first place, next thing the same woman rang me back one hour later and said b.t. would be pursuing this matter and i should contact the debt collection ageny, i refused to pay and told her to take me to court,she also said that their were notes attached to the file and a recording made of my conversation with b.t.and me ,i asked for a copy but she asked for £10. 99 plus vat to which i refused and that stated that i had placed and order for b.t. broadband,i then said i will be seeking advice from a solicitor and would see them in court.
Regards Jim please comment on this matter and if anybody can advise me on this matter.

WOW what a disater Jim,
This is totally not your fault at all, what i would recommend is for you to contact one of the mods on this forum which you can do here http://bt.custhelp.com/app/contact_email/c/4951
The next thing for you to do is collate all your evidence and contact ofcom. You called BT to enqire and not take up the order so therefore ask BT to provide you with a list of account of when you called them, you have a legal right under the data protection act etc to access your data however you may have to pay a fee of £2 to £10 for your records. Also ask for a copy of the voice recordings and or transcripts too because all calls are recorded and monitored for training purposes right!
In any complaint, make sure you can remember the dates and times of call and also names, who did you speak to today??
i hope this helps, the mods will help too!

How much broadband usage does downloading the illustrator CC trial use up?

Presumably non critical, being more a question of download time depending on what you have available.
But you can ask in this specialized forum:

45 minutes into editing, CS3 crashes every time...how much free space does it require to run?

I have noted the error, but cannot contact Adobe with question. How much free space does it need to run efficiently? This happens every time I try to edit and is costing me so much time, it is not worth using this product. Help...

Hi,
I am sorry to hear that you are experiencing this problem. First, I would need to know what kind of computer you use. You should usually alllocate at least 30% of storage for photoshop files, rendering etc.
Also, it is important to know if you have a computer that is capable of handling large files(as they will need a competent video card processor, RAM and processor speed).
Does the problem usually happen for large files or only one?
Let me know if you find this information useful,
Vicente.

How much of Java is involved

1.How much of Java is involved in Oracle Portal. If someone wants to just use the functionality available out of box from Oracle Portal, does it involve any use of Java.
2.Can someone give an example of extending the functinality of Oracle portel using Java and XML.
3.How much of Java knowledge and skill level is requried to start working or learning Oracle Portal.
Thanks

The use of Java for extending Oracle Portal with portlets is optional. You can build portlets via Java programming, but you can also build them without Java programming, for example, Web Clipping, PL/SQL, Omniportlet, and Portlet Builder require no Java knowledge. The OracleAS Portal Developer's Guide has an excellent chapter on choosing which technology to use for building portlets. It considers such factors as whether you know Java in helping you decide what to use.

Hi
I am going to be buying a macbook air 2012 model with 4 GB ram soon. I was wondering how much space (memory) does Norton AV take up and does it drastically slow down the computer. Also, I am going off to uni so will predominantly be using the laptop for surfing and MS office.
Thanks a lot

Sorry to disagree mende1. In this age of email attachments and social networks, it is actually a good idea to have a good antivirus on your system. {I realize that this is a religious argument and I will say no more}. With that said, the general concensus is that Norton AV is terrible. It is intrusive and uses up a lot of cycles.
There are a lot of better AV clients out there. I use ClamXav which is free and uses the clamav antivirus that is open source.

Hey there RMBrizzolara,
It sounds like you have downloaded iTunes from the download site, but when you connect the phone to your computer you are prompted to update iTunes to 11.1. I would start by opening iTunes and then verifying the version that is running with this article:
iTunes: How to find which version you are using
http://support.apple.com/kb/HT1208
On Windows
Open iTunes.
On the Help menu, click About iTunes. A window appears with scrolling text. The first text that appears displays the iTunes version (press the Space bar to freeze the text if it's moving too fast for you to read).
Also when you download the iTunes installer, you MUST double click the file that was downloaded to install it.
You can check in your Programs folder and try running the iTunes application from there to see if that works.
Cheers,
Sterling
