Question about design - use patch-panels or switches in racks?

I'm trying to suggest should I use patch-panels in server 19" racks and use stand-alone telecomm racks for access layer switches
OR
should I install 2-3 access layer switches in every server rack?
First version looks more correct, but than I have to use MUCH MORE cables, organizers etc - all of it eats place in data-center.
Maybe someone saw some guides for that question?
Thanks!

2 or 3 access layer switches in every server rack? Considering typical stand-alone rack switches offer 24 or 48 ports, how many servers per rack or how big are these racks?! Or, were your intended access layer switches only 4 port switches?! (laugh)
The main disadvantage of rack switches, you either run out of ports or have too many ports. Since server hosts often push bandwidth harder than user hosts, you also have the issue of how much aggregate bandwidth you need to move out of an individual rack. These issues are better addressed by your suggestion of using patch panels from each rack that come to a network switch rack.
You're correct, all the cables, and their organization, has an expense, but this has to be considered against switch costs. Assuming you intend to use Enterprise switches that offer gig to the servers and perhaps 10 gig uplinks, there's a cost to having extra swiches by deploying to each rack. Also switches per rack would disallow the advantages you might find with a chassis switch in a switch rack. Further, depending on performance to provide, do you want to be limited by uplink bandwidth from each rack, or pay for high bandwidth from each rack that's usually underutilized.
Besides "looking right", the foregoing is often why there are server rack patch panels, etc.
One design, that I found interesting, was using the 3750 "stacked" across racks (guess you could do same with newer 2975s).

A question about design of Java Application on java card.

Hi every one,
I have a question about design of Java applet on java card,
There is an application on my card that it is not java card, it include a DF and some EF under DF, I would like to know if I want to have this application on java card ,how can I design DF and EF on java card ,I mean is there any relation between DF,EF with applet and file? for example can I say DF is same as applet and EF is same as file?
I'll appreciate for any help .
yours sincerely,
orchid

hi
you can write a java class for DF.
an instance of DF class have some EF objects.
for example,
samples/com/sun/javacard/samples/JavaPurse/CyclicFile.java
implements ISO 7816 CyclicFile ( EF )

Question about Automator using Spaces.

I don't think this is the right place for this question, but I figured I am probably going to need to write an applescript to do what I want, so I decided to put it here.
I have an automation to open some Word documents on my idisk, then open Dictionary, then open Safari with some tabs. But the problem comes in with spaces. I have Word and Dictionary open on Space 1 and Safari open in Space 3. When the automation ends, I end on Space 3 and would like to know how I add a function to set the focus back to Space 1. It's not all that detrimental to the success of my Automation, but I only use Safari for research and would like to focus to end back on word. I have tried switching which apps open first, but I still end up on the 3rd Space.
My other question is, where can I go for reference to commands in Xcode and AppleScript that deal with Spaces? I love using that function and I have had some ideas about scripts that could help me with them, but I don't even know were I would start with commands.

There are several solutions to this.
The first option would be to send the appropriate key command to switch to space 1. If you've left your preferences as the defaults then you can:
<pre class=command>tell application "System Events" to keystroke "1" using {control down}</pre>
Which will send a Ctrl-1 and switch to space 1.
An alternative, which may be even better, is to activate the application you want to be frontmost:
<pre class=command>tell application "Microsoft Word" to activate</pre>
This should activate the application and switch to that application's space.

Question about Design Standard licence

Hi!
I would like to know, when you buy a licence Design Standar, this is only for one computer or you can install it on 2?
I'm trying to understand also about volume licence.. This is useful only when you have how much computer? we are going to have maybe a maximum of 6 computer using that suite.
Thanks!
Christ

Hi Christ, here's an overview guide to answer all those questions and more on Adobe volume licensing...

Question about design pattern - business delegate

hi guys
i have got a question to ask about the delegate pattern. usually, we use it to decouple between presentation client and businessservice tiers. for instance, the service tier has an session ejb, and delegate wrapps the ejb. and the web client calls delegate to access service. is the delegate only used by the presentation tier? within the service tier, we can have many ejbs that work together to get tasks done. do we still use delegates in the service tier? what is ur suggestion? thanks

Qosmio G40-10Z: Question about energy use in sleepmode

When I turn my new Qosmio G40-10Z in sleeping mode, with full battery (and off the AC power), I can't start the computer next day. I can only start it up after connecting it to AC power. I get a message windows Vista wasn't closed properly and I am asked to start in normal way or safe mode.
After starting the battery indicates only 2% power. So, what is using power in sleeping mode? Why isn't the sleep mode not transferred to hibernation state when the battery is almost empty?
(New notebook, only vista and office installed and only television antenna is connected)

Hello guys
At first I just want to write a little bit about theory. Microsoft has implemented standby/Hibernation mode to offer PC users comfortable OS usage and make switch ON/OFF time much shorter.
According to the definition standby mode should be used for short time (launch, meeting and if you must leave the notebook for few hours). Hibernation mode should be used if you leave the notebook over the night or maybe day or two. In standby mode all data will be written in RAM and to keep them notebook needs power. In Hibernation mode all data will be saved on to HDD and notebook can be switched OFF. In hibernation mode the notebook does not need permanent power supply.
For me it is really strange that you use standby mode with battery and almost 20 hours. With this I do not want to say that described battery issue is normal but for 20 hours it is logic to use hibernation mode.
Back to battery issue: only 20 hours under standby mode is really to short. I have tested it with my Tecra and after 5 days I was able to switch ON notebook as usual (only battery power supply.
In your case I see only two explanations:
1. Somehow notebook can not switch into standby mode properly and stays running (I do not believe this because you can see if something like this happen)
2. The battery is defective
What you should do is to contact Authorized service partner in your country. Make a call and explain the situation. Maybe you will get new battery or they should test it using your battery.
Sorry for this long posting. I wish you luck and hope you will clarify this issue very soon.
Bye and good luck!

Questions about Designer

Hello,
I am new in this forum and in Oracle Designer also.
I have started to work with Designer last month,
I am learning to use it,
and I have a question :
- what is the difference between Template object and object library???? waht ares the uses of both them ?
- waht is the difference between Designer et Designer headstart?
thanks for your help ans have a good day,

I'll give you my opinion based on my experience...
Templates serves as 'skeletons' of generated forms and reports. You use them to define global appearance and functionalities of the module, but not details like specific item properties.
The object libraries define the details of the generated objects, like items, canvas, windows. Many properties you can't define using templates, but can do using object libraries.
Usually to generate an app you rely on both templates and object libraries, as well on preferences.
I've never used headstart, but I think it's a kind of "add-on" to Designer, with pre-customized templates, object libraries etc (maybe it can be thought as a framework?)

A question about design.

I have a program I wrote using Visual Basic that I use at my church to print a deposit slip for our weekly offerings. A pretty simple program. I enter the check information (giver name, check number, amount) or cash and put that data in a list
box. I also total the cash & check amounts to print on a deposit slip. One aspect of the program is that I store the name and address of anyone who gives to the church and at the end of the year I print a letter giving them the total of their
offerings throughout the year so they can deduct it on their income tax forms. The names and address are keep in a simple access database.
Now, I have added the capability to insert the check in a Magtek MICR check reader and using the account number on the check (which I have stored in the database in the same table that holds the names) I can get the name of the person making the contribution
along with the check number. Then I just enter the amount, hit enter and I'm ready for the next check.
Here is the problem (and it's not a big one): some of our members have two or more checking accounts so I end up with two rows with duplicate information in my database. My question is should I create another table with the account number and a key
pointing to the member name? I know, I've been kinda wordy for such a simple question but I really want the views of the members of this forum.
Thanks in advance.
Philip

Philip,
Just thinking out loud. How about having seperate tables for the personal info, account and contribution?? Something like below:
Person
PersonID, Name, Address and other personal details
BankAccount
Account_ID, PersonID, Branch_details etc.
Donation:
Donation_ID, Person_ID, Account_ID, Check_Number, Amount, Datetime etc.
So you can have a track of all names and accounts seperately. Now for the contributions, if a person has given two checks each with different bank account, the same can be captured distinctly with the combination of Account, Check and Donation id. The Person_ID
can be removed from the last table if we can assume that each account maps to only one person (eliminating the possibility of shared accounts)
Thanks,
Jay

Question about forum use regarding an error I am receiving

I am looking for an answer to the proper process I should follow when running into issues with Azure Storage. As I don't want to annoy folks with tossing questions into this forum regarding errors I'm running into that are more usage related instead
of technical in scope.
For instance this morning I was attempting to view some details about a particular Storage item and was greeted with the following screen in the Azure Portal.
I was able to accomplish what I needed to (downloading some files out of this particular storage account) within the Manage.WindowsAzure.com site without issue. So this seems to be connected to the portal itself and it's interactions with Storage
(perhaps). I now have access to the above Storage item via the portal site, but for about 15 minutes I continually received the message above. Even after logging out, clearning cache, trying different browsers etc.
So my question(s) are; Are these forums the proper place to be posting information about issues we run into? If not what is the preferred method for reporting items like those above and getting help with remediating them in a timely manner?
I'm happy to put them here, just want to make sure there isn't a better place as I'm new to this.

Hi Darren,
You can post your issue with Azure Storage in here. Just make sure that you do not give out any PII data.
Also, the above portal which you are viewing is still in preview. You may use "manage.windowsazure.com" portal to access your resource.

Some questions about the use of the relay

I connect Relay coil to the AC power source,but the switch always act.Is there any suitable relay for ac power ?
and when I replaced time delay relay in simulation, there was an error. I don't know how to get the right parameter setting ?
please help.

time_delay relay.png ‏5 KB

Hi there,
Thank you for your question. There are two ways to do this, for your origianl circuit you can connect the time delay relay in this way:
Set the frequency of the source to 1Hz and simulate, then you can see the NC and NO switch back and forth.
Second method: Instead of using a AC relay, we can use an AC coil which can be found at Electro_Mechanical-->COILS_RELAYS-->ENERGIZING_COIL_AC
In addition, we can add a normally closed (NC) contact or a normally open(NO) contact spicified for this AC coil(say K1)
Just type RELAY_CONTACT_NC or RELAY_CONTACT_NO to place the components and then place them under K1.
Change the Controlling device reference as shown in the picture below,
Now the AC relay can be constructed in this way.
For time delay, we can use TIME_DELAY_NC and TIME_DELAY_NO contact
Hope these two methods help!:-)
Best,

thanks, but i don't think i follow what u said.
bascially i was asking if it was still a good idea to use delegates to communicate between ejbs the same way presentation tier calls service tier. i.e. SessionEJBA calls DelegateB to access SessionEJBB. or SessionEJBA calls SessionEJBB directly including the lookup, etc.

Question about planning using serialization point in transaction S2L

Hello colleagues!
Iu2019ve try to implement the supply of production line (supply area) just in sequence. R/3 received dependent requirements and backflushes of serialization point behind target Supply Area from APO.
Then I got a few dependent demands with indicator u201CXu201D in u201Crequirement is serializedu201D field in transaction S2L. I started the automatic planning but replenishment proposal was created to cover all dependent demands. from the selection horizon (with ind. u201CXu201D and without ). But I need to cover dep. demands only with ind. X in u201Crequirement is serializedu201D field. I looked through SAP help and SPRO but I couldnu2019t find helpful information.
Please, help me to find solution.
Thanks.
Ivan.

Thanks for the feedback. I followed the link but I guess I just don't understand about the extended file system. Is HFS+ the same as Mac OS extended (Journaled).
Basically, yes.
I understand that I guess that case sensitive means just that, but what is the difference between journaled and extended? Does it mena that a log file is only saved for the journaled system?
When a filesystem is journaled, all changes to it are written to a log.
Do most people just format as Extended without journaled? I am about to reformat my iMac and install Leopard on there and I was wondering if I should format using the extended or the extended with journal?
Using the journaling option slightly decreases the amount of space on the drive usable by you and increases the chance of recovering data from the drive if a problem occurred. If you want, you can use the Disk Utility to turn it on and off without erasing the drive again.

Question about Parallels using Bootcamp partition

I was about to install XP on bootcamp but i would mainly be using parallels to run XP from the bootcamp partition. What i was wondering is that if i was to make any changes to xp like install a software and create a new folder through parallels, would it reflect on the actual bootcamp partition when i load into the actual XP partition using bootcamp? Basically, do the changes made to windows using parallels carry over to the bootcamp partition given you are using the bootcamp partition on parallels?
Thanks

Thanks a lot. While i am at it, if i use the bootcamp partition with Parallels, i cannot suspend the VM right?
Parallels will behave the same, whether it has its own copy of Windows, or is using that on the Boot Camp partition.
The only difference is backup. If you use Parallels with Windows in a disk image file (Preferably a sparse bundle), Windows can be backed up with Time Machine. If Windows is on its own partition, Time Machine can't handle it.

Quick question about custom Components and Panels

Okay, so here is the situation.
I created a custom component that overrides paintComponent. All this component does is draw a diagonal line.
If I add this component directly to a JFrame it displays fine.
The issue: I made a custom JPanel that at the moment only contains this component. If I add it to the JPanel then add that to the JFrame, it only displays a dot.
Any suggestions?

Layout issue. The intermediate JPanel has a default FlowLayout manager which shows its child components at their preferredSizes. These sizes are computed by the layout manager in the process of laying out the children. When there are no children the size reported to the parent is the default size which for JPanel is (10, 10). You can change the layout manager for the intermediate panel or specify a preferredSize for the graphic component in one of two ways:
1 - use the setPreferreSize method
2 override the getPreferredSize method in the class:
class Pseudo extends Jpanel {
    protected void paintComponent(Graphics g) {
        // custom drawing...
    public Dimension getPreferredSize() {
        return new Dimension(desiredWidth, height);
}

A basic question about font use when creating a banner ad in PS

I am creating my first ever web ad in PS (Mac, CS4). When finished, I'll Save for Web as a JPEG. The design is basically just some text superimposed over a photo. Am I free to use whatever font I choose? Or do I have to use one of the "web safe" fonts that (almost) everyone has installed?

the way u are creating it everything is rasterized... ie even the "text" is an image... so yes u can use what ever font u like...
