I have a few questions regarding ADT.

First, please check my understanding of ADT.
ADT is a set of specifications which tells how the data is to be operated and structured. Please correct me if I'm wrong.
Now, here are the questions.
1. What are the atomic and structured ADT? I was googling around but I couldn't find the information about them anywhere.
2. what is the difference between the specification and the implementation of an ADT?
Also, if you have a website which has a detailed information regarding ADT please tell me the website.
thank you!

please suggest more websites.Here's 318,000 suggestions:

Hi, I want to downgrade from OSX LEOPARD to OSX TIGER but I have a few questions regarding this. My iMac is originally from Sep 2007 it came preloaded with tiger. I have original install (2) tiger discs version 10.4.10. I want to know if it is safe and what are the necessary steps to do so. Also by downgrading im wondering if a lot of apps nowadays support tiger for example I have photoshop version 5 and 4 these are very important to me. One last question does anyone know of any reliable virus protection for mac that doesnt slow down your computer? because I have read that a lot of them do so. If anyone can help me I would greatly appreciate it! Here are the specs for my iMac

Most of the time a perception of general slow performance is the result of installing third party junk alleged to speed up, "clean" or "optimize" your Mac, or to look for viruses that don't exist. Ideally you would know what you installed so you can uninstall it, but if you don't know or aren't sure there are techniques such as Safe Mode and creating a temporary user account to confirm that suspicion.
If you open Activity Monitor it may show a process, or processes, that occupy a lot of your system's time.
Slowness confined solely to web browser activity is often the result of an inexorable progress toward websites that demand ever more processor-intensive tasks. If your slow performance is strictly limited to web browsing, you might try disabling Flash by either uninstalling it, or use utilities such as ClickToFlash that allow you to control what Flash content gets loaded. Flash in itself is not inherently evil, but there is nothing to stop websites or the advertisers who pay for them from writing horrible Flash code that can do everything from hogging 100% of your CPU's time to causing random crashes. You can watch Activity Monitor as in the above to correlate these troublesome web pages with performance degradation.
You are correct; if your computer shipped with Tiger you may certainly revert to it. I forgot that Tiger was shipping on new Macs as recently as five years ago. To downgrade it would be necessary to completely erase your hard disk and boot with the Tiger installation DVD, followed by installing it anew. Such drastic measures are not necessary and you are unlikely to be satisfied with the results anyway.
Assuming your system is free of third party parasitic junk attached to OS X in an ill-conceived attempt to improve upon it, that your hard disk drive is sound and the boot volume has enough free space to work with, by far the best performance-enhancing improvement would be to add more memory. Buy as much as your computer can use and that you can afford. 2 GB is not that much any more.

Totally new to external hard drives and have a few questions

Since beginning my search for an external hard drive this morning I have learned that I know very little about this subject. I really have very little knowledge of all the computer lingo used when looking at these devices. I have a few questions regarding this, if someone could help me.
1. Are all external hard drives compatible with my mac?
2. Do I need time machine if I have an external hard drive?
3. I have two PCs in addition to my mac. Can I use the same external hard drive for all three or would I need a separate one?
Thanks for helping!

Use a Firewire not a USB drive.
I have had many reliability issues, and compatibility issues with USB over the years (starting with the original iMac), right up to the PowerMac G5 and Mac Pro - devices not working properly with hubs, needing to be plugged directly into ports on the computer (even though there aren't enough), etc, etc.
For me Firewire devices cause fewer of these sorts of problems.
Firewire is "isochronous", basically meaning that you can pump "clocked" data though it in real time. USB works more like TCPIP, with the data chopped up into packets and later reassembled. (Thus, at a minimum, you have latency, that is, the wait for the data to be "put back together".) Second, the Firewire protocol allows more direct address to memory (including mass storage) with minimal intervention of the CPU.
No collisions, no glitches. Firewire is rock-solid.

Oracle 9i R2 Installation on RH Linux 7.3 -- Have a few questions.

Hello,
I am at the end of the Oracle 9i R2 installation and have a few questions.
1) The "Agent Configuration Assistant" keeps failing. I get the following message.
Parameters "orahome" = /opt/oracle/product/9.2.0
Parameters "nodeinfo" = NODE_VALUE
Agent Service Failed
What does this mean and how can I complete Agent Configuration Assistant install?
2) I completed the Oracle Database Configuration Assistant successfully and created passwords for sys and sysoper (not sure if these were the exact users). Note I did not modify any other users or unlock them.
How do I log into the sqlplus prompt, what users should I use and how can I create new users and databases?
Thanks for your help in advance.
Regards,
Chris Barone

(1) You can probably just ignore the Agent Configuration (are you using the Agent to collect data?)
(2) sqlplus '/ as sysdba' will log you into the SQL*Plus prompt.

Few questions regarding the "Update CMS" button

Hello,
Few questions regarding the "Update CMS" button:
1. When I create new product at the SLD I see it at the add SC table even if I don't click the "Update CMS" button first. If so, when will I use this option?
2. When I do click the "Update CMS" button it takes it between 30-40 minutes to finish the update. During this time frame the whole development portal (it is sitting on the same WAS as the NWDI) becomes extremely slow. Is this normal response time or do I have a certain performance problem with my server?
Thank you in advance,

New to IPhone and have a few Questions?

To start I want to say that I am a long time (25+ years) veteran of technology but am new the the IPhone. My IPhone is not Jailbroken and would like to keep it that way if I can. Allthgouh I did jailbrake it with blackra1n for about 30mins then I did a factory reload and let it be as it started acting stupid once I started installing apps from unofficial sources.;) Im a x86 nerd and NOT a MAC guy. I haven't sat down at a MAC/Apple in about 15/20 years.
I just got my first IPhone 3Gs/16GB. (Coming from a BlackBerry Curve 8310) the other day and although it is taking some time getting used to, I think I will like it more then I do once I get used to it.
Anyhow I have a few questions to start off with. I did some googleing already but just want to make sure I understand a few things.
All though I did the BlackRa1n jail break thing and installed a few apps then it locked up and failed to turn on or something so I did the whole reload from itunes and now its all good. Anyhow.....
1.) It appears as if one can not run a program from the home sreen and have it run in the background while doing other things? Take the many SIP Clients I have played with in the last 48 hours. Once I open the SIP Client and connect if I hit the physical button below the screen the program closes, thus the sip client no longer works. Pretty much most if not all apps iv installed from the App Store act like this. Is this the case? Does the IPhone not mutitask at all or verywell?
2.) Are there any SIP Clients that work over 3G? All the ones iv tried say they are for WIFI only. The SIP Clients work fine when on WIFI. It sounds like this is Apples way of controlling/monopolizing the voice/data/voip aspect of the platform/device. Im sure they would lose a lot of money if everyone did what I am trying to do.Just my opinion.
3.) Maybe I play with it to much but **** the battery dies fast. Is there anyway to optimize the battery at all other then for me not to use it as much?
4.) How can I remote lock it if I lose it or it gets stolen? I read somewhere this could be done.
5.) Are there any other Shells/HomeScreens/Themes that can replace the standard 4x4x4 row icons?
6.) The speaker phone (when on a call) seems kinda low even when turned all the way up. Is there any way to make it louder?
7.) I am using the built in VPN client to connect to my works PPTP Windows 2003 VPN server but the client randomly disconnects through out the day. Is there any way to have some type of keep alive set or are there any other VPN Clients that I can use?
Sorry for all this just thought I would ask for feedback.
Many thanks for any help anyone can provide,
SomeOneOnLine

1.) It appears as if one can not run a program from the home sreen and have it run in the background while doing other things? Does the IPhone not mutitask at all or verywell?
The iPhone SDK does not permit ANY 3rd party apps from running in the background or multitasking. It does provide for push notifications which can simulate certain background activity in terms of receiving external notifications while the app is actually closed. This works reasonably well with IM apps, news, sports, weather, travel updates and some peer-to-peer games.
2.) Are there any SIP Clients that work over 3G? All the ones iv tried say they are for WIFI only.
Just how would the SIP server connect to the cell carrier 3G network? Do you know of ANY that do??
3.) Maybe I play with it to much but **** the battery dies fast. Is there anyway to optimize the battery at all other then for me not to use it as much?
3G voice and data connections are culprits. Avoid email push and frequent fetching. See this Apple article for detailed suggestions.
http://www.apple.com/batteries/iphone.html
4.) How can I remote lock it if I lose it or it gets stolen? I read somewhere this could be done.
MobileMe Find My iPhone will locate, set a passcode lock and optionally wipe all data from your iPhone. You have to be a MobileMe subscriber.
5.) Are there any other Shells/HomeScreens/Themes that can replace the standard 4x4x4 row icons?
No. Apple does not permit this.
6.) The speaker phone (when on a call) seems kinda low even when turned all the way up. Is there any way to make it louder?
You can troubleshoot your iPhone as described in the User Guide - restart, reset, reset settings, restore. Or, get hearing aids
7.) I am using the built in VPN client to connect to my works PPTP Windows 2003 VPN server but the client randomly disconnects through out the day. Is there any way to have some type of keep alive set or are there any other VPN Clients that I can use?

Thinking of getting an iPad but have a few questions

After using the iPhone 4 (3GS previously) and really liking the OS on it, I am thinking of purchasing an iPad to make reading ebooks easier, also, having the iPad would be more convenient for me to quickly go on the net in my home (or other wifi area, but mostly home use) to seek information and also check, send emails, rather than having to switch the computer on all the time and then having to wait for it to load up and also with the iPad, the larger screen would make email, internet use and ebook use more pleasurable due to the iPad's larger screen when compared to using my iPhone.
I have a few questions that I would like to ask to iPad users, who could perhaps answer them for me?
In my household we have 2 iTunes libraries, one for my iPhone and one for my girlfriend's iPod. I created a separate iTunes library for each of the devices so that each one would have a totally separate library and therefore the possibility of having one overwriting the others library would be impossible.
Now ideally I would be wanting to create a separate iTunes library for the iPad, but I would want to add the music and apps, email accounts, bookmarks that I have on my iPhone and add them onto my iPad. Would this possible?
Also. I believe some apps have specific versions for either iPhone or iPad, so would the iPhone versions of the apps run on the iPad, or would I need to download the iPad versions of those particular apps?
Also. I have a number of DVD's that I have converted and then dragged and dropped the video off of them into iTunes. If I am correct, would I need to reconvert those videos/DVD's again, as the video size (screen size) would be for the iPhone and therefore a smaller screen, which would not look very good on the iPad's much larger screen. If this is the case, can anyone recommend a good video converter for converting video for the iPad and what settings need to be used for the iPad?
I also would be wanting to have a number of photos on the iPad. To get them onto the iPad, is it just a simply matter of selecting the pictures I have on my computer that I want added to my iPad, and then just dragging and dropping them into iTunes, then connecting and syncing the iPad to get them added on to the iPad, or is there an easier method?
Thanks in advance

Funny you should mention Macs, but I'm thinking of my next computer been an iMac, and using the Parallel Desktop software so that I can have functionality of been able to switch to Windows when needed to run the programs that are not Mac compatibly. I'm swaying towards Mac has I have heard their OS is more reliable and secure compared to Windows, and the need to have anti virus and anti spyware programs on a Mac is not really needed, but I figure if I can run Windows on a Mac then I have the best of both worlds, anyhow back on to topic
I do indeed take backups of the various libraries and related data for them.
I have used the Dropbox app and was impressed, but I did prefer an app called iFiles which allows me to carry various files/files types around with me on my iPhone, such as PDF files, Word doc files etc.
The reason I use the method of having a separate iTunes library for each device we use on the computer, (my iPhone, girlfriend's iPod, and soon maybe an iPad) is because I accidentally replaced the music I had on an iPod I had at the time with my girlfriend's music. So from then on, that's why I have created a separate library for each Apple device, and so far I have never accidentally messed up another devices contents.
Thanks for the help its much appreciated.

Owners of the 80GB iPod classic, I have a few questions

Ok, so I got my 80GB black iPod classic today and have a few questions, one of these I will need you to check something on your classic.
1: Can you get the digital booklets from the albums purchased on the store on your classic?
2: Is it normal for the hard disk to make that noise when it's spooling?
3: I've noticed this, is there a slight delay switching to the "iPod" screen from the screen before it? I need some one to check this.

All hard disks make a bit of noise. The Classic uses a memory cache to allow it to stop the hard disk and thus save power. When you switch screens, the delay is due to the hard disk spinning up and/or searching for the next thing to display. In short, it's the price we have to play for 80/160Gb of space.

Switching from PC - Have a few questions

I have read the forums and talked to AppleCare support and I have a few questions on the Mac Pro.
1. I was told by Apple that using RAM other than the overpriced "Apple" brand would void the warranty (I typically use matched Mushkin or Crucial)- is there any point in getting the AppleCare insurance then?
2. Appple told me that Western Digital Raptor 10,000 RPM HD's were not supported, yet I see a number of you use this drive - are you using a SATA adapter or putting it one of the 4 drive bays?
3. Am I limited to Apple's Superdrive DVD/CD or will any ATAPI drive work?
4. The graphics card situation is pathetic - does anyone know is there are planned updates before I spend $700 on 2 ATI 1900's to run 2 30" Cinema displays. Does Apple typically come out with new products at the same time each year?
5. Does anyone know of software to control multiple monitors i.e. Designate virtual desktops on a specific monitor, or specify that Application A opens on monitor 1 while Application B opens on monitor 2?
Any help will be appreciated - Apple doesn't seem to be very forthcoming on these topics - I am still anxious to rid myself of the virus a day problem and Microsoft software that becomes slower and less productive with every revision.

1. I was told by Apple that using RAM other than the overpriced "Apple" brand would void the warranty (I typically use matched Mushkin or Crucial)- is there any point in getting the AppleCare insurance then?
It won't void the warrantee (unless you damage the computer when installing it), but it won't be covered. If it goes for service, remove the non-Apple memory first (it's a good idea to do that first, anyway, to see if it fixes the problem).
2. Appple told me that Western Digital Raptor 10,000 RPM HD's were not supported, yet I see a number of you use this drive - are you using a SATA adapter or putting it one of the 4 drive bays?
Same as above.
3. Am I limited to Apple's Superdrive DVD/CD or will any ATAPI drive work?
No. Most ATA (or SATA) optical drives will work.
5. Does anyone know of software to control multiple monitors i.e. Designate virtual desktops on a specific monitor, or specify that Application A opens on monitor 1 while Application B opens on monitor 2?
Many application remember the last monitor they used. Some (e.g. Graphics Converter) have preference settings to put the main window on one display, the controls on the other. Some (e.g QuickTime Player, VLC have view settings to put the full screen output on a selected monitor.

Have a few questions about iPad before I get one

I have a few questions about getting an ipad before I committ to get one.
I have about 24 gb of itunes purchases in my itunes library, I am thinking of getting the 64 gb ipad. However, after you purchase the 64 gb, it will not truly be 64 gb,
1) how much actual storage space would I have on a 64 gb ipad accounting for the os? On my macbook now I have a 164 gb hard drive but only access to about 148 gb for example.
2) Would I be able to store the 24 gb of itunes purchases in icloud? How would I do that? Would I keep needing to go into the Purchase History tab in the ITunes store and download the song when I want to listen to it? My concern with this is that the item will no longer be "available in the Itunes store" and I will lose access to my music I purchased?
I would like to ditch the laptop and just have the ipad as my computer but want to know about these questions I have first.
3) Can ipad and iphone now be charged without needing a laptop? Per last year's June 2011 conference when Lion and ICloud were announced, it was stated in Fall 2011 with iOS5 that people could get ipads and iphones and charge them without needing a laptop for syncing?

1. About 57 on mine
2. Subscribe to iTunes Match at a cost of about $25 per year - 25000 song limit I think
http://www.apple.com/icloud/features/
3. The iPad comes with a power adapter that plugs into a wall socket and that is the recommended way to charge it anyway. - not by using a computer
http://www.apple.com/batteries/ipad.html
You do not absolutely need a computer in order to use an iPad but you have to do more research to figure out if it will fit your needs that way.

Just got a MB, Have a few questions

Ok, so I have just received my white MacBook, Everything is great super fast machine.
However I have a few questions about the Finder.
The Hard Drive on this computer is 160GB, I have added 11 or so GB of music and a few other files, the computer says I have 123 GB remaining which is probably right. So my question is how much space does leopard Take up? (How much space is usually free on newly purchased computer?)
How do you uninstall programs in OS X?
Lastly, is there any easy way to tell where the hard drive space is being used? (Kind of like the pie charts in Windows Explorer)
Thanks

Leopard on its own takes up about 9 GB. An additional 4 to 5 GB is taken up by additional applications that come prebundled with a Mac. To find out what's occupying space, see my FAQ*:
http://www.macmaps.com/diskfull.html
Most applications uninstall by just dragging them to the trash and emptying the trash. Some leave behind crumbs in the preferences or library folder, and come with their own uninstaller program on their disk image or optical disk installer. A few have no uninstaller but can be removed with http://www.appzapper.com/
Check with the vendor if there are specific system independent resources they install, so you don't find yourself with resources that won't survive a system update, or the installation of another application which require those resources to be of a different version, such as fonts.

A few questions regarding SAP EWM and WM

Hello,
I have a few general questions regarding the differences between EWM and WM:
1) What are the benefits of EWM-MFS compared to WM + TRM (especially in terms of SPS)?
2) The Quality Inspection Engine (QIE) can also be used by SAP WM, right?
3) There is RFID-support in EWM, so EWM is able to communicate directly with SAP Auto-ID, right?
But I have heard that SAP PI is necessary in some cases, when and why?
4) Is there something new in EWM regarding goods receipt processing?
I have read that the splitting of inbound delivery items is possible in EWM in case of missing inbound delivery items. Is this really a new feature?
5) EWM can easily be connected to SAP BW for reporting purposes, what about WM?
6) What about scalability if the warehouse grows?
7) Is there any information about the costs of using EWM compared to WM and vice versa?
I appreciate any kind of help.
Thank you.
Dennis

Hi,
1. What does SAP offer as a product for dWM? Is it a u201Cspecialu201D installation of the SAP framework dedicated to WM or is it a standard ECC box where only the WM module is used?
There are two version of DWM. One is Decentralized WM as a part of ECC and another one is EWM as a part of SCM. Both are decentralized.
2. My understanding is that the interfaces between ERP and dWM can support some non-real time operations (like when the main ERP system is down, the dWM can still perform some operations). Considering that the transactional interfaces are based on BAPIs, how does SAP achieve this interfacing in non-real time environments? I am thinking you can complete the different processing unless both systems are up
When it comes to interfaces, DWM needs Deliveries from ERP. That's it, WM can function from there independent of ERP system. But, WM defenitely needs to communicate back PGI and PGR and other posting changes . So, in case ERP is down, even though PGI / PGR is done at WM end, they may not be communicated back to ERP. But WM generates PGI/PGR IDOCs which can always be reprocessed at WM end to resend them to ERP so that Inventory levels are accurate.
Hope that helps
Thanks
Vinod.
