Design question about APs and WLC

We need to know if (and how if possible) a WLC may control several APs, configured in a parallel grid array as bridges:
CPD---AP(l)------air---------AP(r)---AP(nb)
|--AP(l)-------air--------AP(r)---AP(nb)
|--AP(l)-------air--------AP(r)---AP(nb)
The AP(r) right are non-root, the AP(l) left are the root connected to the CPD, there may be several bridge. We need to control all of them, specially the ones in the right = AP(r) of the bridge. And of course the AP(nb)= non-bridge
We would want to know if we can regulate how the right antenaes connect to the left. Right antenaes need to be on a moving platform, and there is no possible interconnection among the AP(r).

Design question about when to use inner classes for models

This is a general design question about when to use inner classes or separate classes when dealing with table models and such. Typically I'd want to have everything related to a table within one classes, but looking at some tutorials that teach how to add a button to a table I'm finding that you have to implement quite a sophisticated tablemodel which, if nothing else, is somewhat unweildy to put as an inner class.
The tutorial I'm following in particular is this one:
http://www.devx.com/getHelpOn/10MinuteSolution/20425
I was just wondering if somebody can give me their personal opinion as to when they would place that abstracttablemodel into a separate class and when they would just have it as an inner class. I guess re-usability is one consideration, but just wanted to get some good design suggestions.

It's funny that you mention that because I was comparing how the example I linked to above creates a usable button in the table and how you implemented it in another thread where you used a ButtonColumn object. I was trying to compare both implementations, but being a newbie at this, they seemed entirely different from each other. The way I understand it with the example above is that it creates a TableRenderer which should be able to render any component object, then it sets the defaultRenderer to the default and JButton.Class' renderer to that custom renderer. I don't totally understand your design in the thread
http://forum.java.sun.com/thread.jspa?forumID=57&threadID=680674
quite yet, but it's implemented in quite a bit different way. Like I was saying the buttonClass that you created seem to be creating an object of which function I don't quite see. It looks more like a method, but I'm still trying to see how you did it, since it obviously worked.
Man adding a button to a table is much more difficult than I imagined.

A question about grub and USB

Hi All
I have a quick question about grub and USB that I can't quite find the answer to by searching. Most of the FAQs discuss booting a full linux dristribution from USB. My situation is this. I am getting a new computer with two drives, the second will be arch and the first will be Vista (for my wife). I want the computer to boot the same way that my wife's machine boots at work so I don't want to install grub on the MBR. So, is there a way to have all of the grub config files and kernels installed on the second drive and simply install to grub boot loader to the MBR of a USB stick? My goal would be to simply plug the USB stick into the new PC and boot arch from the second drive.
Thanks

i cant say for hp's
havent worked on any in a while
recent machines have been coupleof dell's , vaio & emachine
which dells do offer it at least the ones i tried , my laptop does(dell)
all home pc's are built by me which do offer to boot individual drives
what hp you getting it may tell in specs
are both discs sata? if so it might not offer this option with 2 drives of same interface
check your power supply alot of these preconfigured machines put cheap under reated power supplies in there
& will burn your motherboard i just replaced PS(250 watt) & mobo(845gvsr) in an emachines <cheap stuff<
i hope you researched the pc before buying ie : mobo, power supply are the biggest concerns
i find it much more benificial to build my own machine gives me peace at mind. the cost is sometimes more in $ but not always , your biggest expense is time researching hardware
if you live in usa the best places to start looking are bensbargains.net & pricewatch.com
i am not affiliated with either & niether sell the hardware they are just advertisers a place to buy
for costomized machines that i would trust is unitedmicro.com theyll asemble & test before shipping
i have gotten 2 machines so far from them with NO PROBLEMS with hardware (knock knock)
you may want to consider this in your next venture for pc

I have a Macbook Pro june 2011... I have 8GB ram but I only have 256mb VRAM... I've read some other questions about this and I realized... Why do I not have 560mb of VRAM since I have 8GB of RAM? Is there any way to get more VRAM to play games on steam?

I have a Macbook Pro june 2011... I have 8GB ram but I only have 256mb VRAM...
I've read some other questions about this and I realized... Why do I not have 560mb of VRAM since I have 8GB of RAM?
Is there any way to get more VRAM to play games on steam?
I've learned by reading other topics that I can't upgrade my graphics card on my Macbook Pro because it's soldered into the motherboard or somthing like that, but please tell me if there is any way to get more video ram by chaning some setting or upgrading something else. I'd also like to know why I only have 256MB of VRAM when I have 8GB of RAM, since I have 8GB of RAM I thought I was supposed to have 560mb of VRAM...
So the two questions are...
Is there any way to upgrade my VRAM, so that I can play games on steam?
Why do I only have 256MB VRAM when I have 8GB total RAM?
Other Info:
I have a quad core i7 Processor.
My graphcics card is the AMD Radeon HD 6490M.
I am also trying to play games on my BOOTCAMPed side of my mac, or my Windows 7 Professional side.
THANK YOU SO MUCH IF YOU CAN REPLY,
Dylan

The only two items that a user can change on a MBP are the RAM and HDD (Retinas not included). You have what the unit came with and the only way you will be able to change that is to purchase a MBP with superior graphics
If you are very much into gaming, the I suggest A PC. They are far superior for that type of application to a MBP.
Ciao.

A few questions about MacBooks and Parallels Desktop.

I have a few questions about MacBooks and Parallels Desktop.
1) I understand I need at least 1GB of RAM to run Parallels Desktop but what about the hard drive, is the stock 60GB drive big enough?
2) Related to question 1, even if it was big enough to allow me to install and run Windows would the 60GB drive be enough if I wanted to install a Linux distribution as well?
3) This has nothing to do with Parallels Desktop but thought I'd ask it here anyway, do Apple Stores carry just the stock MacBooks, or do they carry other configurations?
Thanks
Keith

1. Depend on how intensive you use that HD for saving data on both Mac OS and XP. For standard installation on both OS X and XP, the space of 60 Gb is enough.
2. Same answer as no 1. You can install all three on that HD space, but the extra spacce available will be less and less for your data. You can save your data on external or back up on cd/dvd and erase it from the HD to keep the free space.
Remember to leave at least 2 or 3 Gb for virtual memory usage.
3. Just call them, maybe they don't have it in store stock, but by appointment they might configure one for you before your pick-up date.
Good Luck

One question about Pricing and Conditions puzzle me for a long time!

One question about Pricing and Conditions puzzle me for a long time.I take one example to explain my question:
1-First,my sale order use pricing procedure RVAA01.
2-Next,the pricing procedure RVAA01 have some condition type,such as EK01(Actual Costs),PR00(Price)....,and so on.
3-Next,the condition type PR00 define the Access Sequences PR00 as it's Access Sequences.
4-Next,the Access Sequences PR00 have some Condition tables,such as:
     table 118 : "Empties" Prices (Material-Dependent)
     table 5 : Customer/Material
     table 6 : Price List Type/Currency/Material
     table 4 : Material
5-Next,I need to maintain Condition tables's Records.Such as the table 5(Customer/Material).I guess the sap would supply one screen for me to input the data of table 5.At this screen,the sap would ask me to select one table,such as table 5.When I select the table 5,the sap would go to the screen to let me input the data of table 5.But when I use the T-CODE VK31 or VK32 to maintain Condition tables's Record,I found it's total different from my guess:
A-First,I can not found one place for me to open the table,such as table 5,to let me input the data?
B-Second,For example,when I select the VK31->Discounts/Surcharges->By Customer/Material,the sap show the grid view at the right side.At the each line of the grid view,you need to select the Condition Type at the first field.And this make me confused very much.Why the sap need me to select one Condition Type but not the Condition table?To the normal logic,it ought not to select Condition table but not the Condition Type!
Dear all,I'm a new one in sd.May be this is a very stupid question.But it did puzzle me for a long time.If any one can explain this question in detail and let me understand the concept,I will appreciate him/her very much.Thank you.

Hi,
You said that you are using the T.codes VK31 or VK32.
These transaction codes are used to enter condition records for standard condition types. As you can see a grid left side having all the standard condition types like price, discounts, taxes, frieghts.
Pl check using T.code VK11 OR VK12 (change mode)
Here you can enter the required condition type, in the intial screen. (like PR00, MWST, K004, K005 .....etc)
After giving the condition type, press enter or click on Combinations icon on top of the screen. Then you can see all the condition tables which you maintained for that condition type. Like as you said table 118, table 5, table 6 and table 4.
You can select any table and press enter, then you can go into the screen in which you have all the field cataglogues you maintained for that table. For example you selected combination of Customer/Material (table 5) then after you press enter then you can see customer field on top, and material fields.
You can give all the required values and save the conditon record.
Hope this is clear.
REWARD IF HELPFUL.

2 question about GPU and Lens correction ,cs5

Hi
i have 2 questions about Gpu and lens correction in Cs5
1)Filter->lens correction->search online
i get often and almost every connection time out at the first click on search online , at the second click i get no online profile
is it normal?
2) question is about Gpu
it run faster , but talking about ajustament layer
like saturation or vibrance for example
i found with the gpu on , a light slow refresh compared with gpu off
i have set cache levels 6 ,history 20
i guess are the defaul
well i add a saturation layer and move the saturation slide ,increase o decrease saturation
with Gpu Off , the changes are immedially , i mean i can see in real time the increase o decrease of saturation
with Gpu On it takes a few(very few) time more
again is normal ?
don't be angry , i'm going to buy cs5 and i'm unsecure ... the price make a big role
thanks

For what it's worth, I also see a timeout on the first [ Search Online ] click, after about half a minute delay. Second click turns up results immediately. This happens each time Lens Correction is started, even without restarting Photoshop, and in both 32 and 64 bit versions. Also note that I started with one profile listed by default (though from the wrong camera) for my 40D with 28-135 zoom.
I alsow noticed that I was seeing progress bar activity in the Lens Correction dialog while I was typing this (even though Lens Correction was NOT the active window) every time I hit the 'L' key. Strange.

Three questions about Java and Ftp

Hello, i've the following questions about Java and Ftp:
1- .netrc file is in $HOME directory but i can't access to this directory from java code. The following line producesan Exception (directory doesn't exists)
FileWriter file = new FileWriter ("$HOME/.netrc");
2- .netrc file must have the following permissions: -rw- --- --- but when i create the .netrc file the following permissions are on default: -rw- r-- r--, how can i change this permissions? (In java code, i can't use chmod.....)
3- Are there any way to pass parameters to a .netrc file? If i get to do this i needn't change the permissions because i can't modify or create/destroy this file.
Thanks in advanced!!!
Kike

1- .netrc file is in $HOME directory but i can't
access to this directory from java code. The
following line producesan Exception (directory
doesn't exists)
FileWriter file = new FileWriter ("$HOME/.netrc");$HOME would have to be replaced by a shell, I don't
think you can use it as part of a legal path.
Instead, use System.getProperty("user.home");
Ok, thanks
2- .netrc file must have the followingpermissions:
-rw- --- --- but when i create the .netrc file the
following permissions are on default: -rw- r--r--,
how can i change this permissions? (In java code,i
can't use chmod.....)Yes, you can: Runtime.exec("chmod ...");
I need to use estrictly the .netrc with -rw- --- --- permissions
Yes, i can use Runtime.exec ("chmod ..."); but i don't like very much this solution because is a slow solution, am i right?
3- Are there any way to pass parameters to a.netrc
file? If i get to do this i needn't change the
permissions because i can't modify orcreate/destroy
this file.I don't think so. Why do you need the .netrc file in
Java at all? Writing a GUI frontend?I want to use automatic ftp in a java program and FTP server, the files and path are not always the same, so i can:
- modify .netrc (for me is the complex option)
- destroy and create a new .netrc (is easier but i have permissions problem)
- use .netrc with parameters but i haven't found any help about it
Thanks for your prompt reply!!!!

Basic question about storage and safety in iMovie '11

A very basic question about storage and safety:
I want to keep a backup of my raw footage on my external hard drive prior to begin working on the movie in iMovie. I want to do this:
1. Upload the digital files from my camcorder to my Desktop *(as opposed to iMovie)*
2. Duplicate that footage/clips.
3. Put the duplicate clips/footage into a folder labeled with the name of that footage (like "Fun At the Dentist" or "Jimmy Learns How to Yodel").
4. Drag the folder with the footage/clips into my external hard drive into a pre-existing folder titled "Backups/duplicates of all of my raw footage/clips." This big granddaddy folder will house all of the child folders of different movies.
5 Then, open up iMovie '11 and import the raw footage/clips from my Desktop rather than from my camcorder.
6. Then I want to make a duplicate of my finished movie and put it in my external hard drive in a "Finished Movies" folder.
I know that the original raw unedited footage will always be in iMovies '11 but I want the original to also exist immediately accessible in my external hard drive.
QUESTION:
Is this viable? Is it wise? (I know it goes an extra unnecessary step, but aside from that.)
*Do you have any precautionary advice?* Should I do something in my iMovies '11 preferences? What?
In earlier years with iMovie '04 or '06 (cannot recall) I made many novice errors and ended up losing audio to my finished movie. I also lost footage.
This time around with iMovie '11 I don't to make such novice, ignorant errors.
Thanks so much for any comments to this question.

Yes I'm sure it will work great for you.
The iFrame format is something Apple has come up with. The reason for its existence is unknown to me so I can only speculate. But it seems to me that Apple "invented" this format in order to have devices such as Ipod/Ipad/Iphone/Ixxx create clips that are editable on consumer hardware such as already mentioned devices but also standard Mac computers, without the need for format conversion.
iMovie converts most input formats during import, which takes a lot of time, and this need for conversion often comes as a surprise to most people new to home video editing.
iFrame has a resolution of 960x540 which is long way from the common standards of 1920x1080 and 1280x720. If your end target is YouTube however, this may not be too bad though. However if you intend to go with YouTube HD, you may find iFrame footage to look wrong since they are effectively upscaled to a higher resolution.
Technically iFrame uses the H.264 algorithm, a smaller frame size (960x540) and a rather low compression scheme. This will result in large files, but the plus side is that the files are ready for editing without the need for any conversion and iMovie will natively edit the files.

Question about RAC and ASM

Hi,
We are thinking about build RAC using ASM for OEM database. It'll have two nodes, oracle 10g and Hitachi san with solaris ( or linux ). I've few questions about RAC and ASM.
1) Do I need to have ASM instance running on each node ? ( most likely yes... but want to make sure )
2) can I share oracle_home between ASM instance and database instance ? what is the best choice ?
3) I'm planning to use shared disks for all files, all databases.... what are the pros/cons ?
4) what should be the installation procedure ? Meaning, first create ASM instance on each node, then install cluster software, build RAC databases...... can someone explain..
5) I believe RMAN is the only option for backup since I'm using ASM, correct ?
I'm a newbie to RAC and ASM..
Thanks,

2) can I share oracle_home between ASM instance and database instance ? what is the best choice ?in 10g you can, in 11gr2 you cannot. and it might be better to seperate them because it will give you more flexibility with patching.
3) I'm planning to use shared disks for all files, all databases.... what are the pros/cons ?if you share your oracle_home you won't be able to do rolling updates. so i recommend to keep oracle_homes local.
4) what should be the installation procedure ? Meaning, first create ASM instance on each node, then install cluster software, build RAC databases...... can someone explain..follow the install guide for your respective version. for 10g you'd install clusterware first, then asm and database is last.
5) I believe RMAN is the only option for backup since I'm using ASM, correct ?pretty much. you could stop your database and dump the raw devices or use asmcmd/asmftp but rman is definitely the best choice

Design question about SNASw, DLSW and VDLC

Hello,
I have a question about Ethernet redundancy in an APPN environment.
Let's have an example with 3 routers running SNASw that are on the SAME LAN (no vlans) as the Mainframe's OSA (one OSA only). APPN is configured on the Mainframe.
Using DLSw+, all downstream PUs are connected to the 3 routers. Can I define in the VDLC interface of each router the SAME MAC address, and this MAC address be the destination MAC of the downstream PUs?

Hi,
yes, headend routers are the ones in front of the OSA/mainframe.
If you replace a tokenring with ethernet in the data center/headend, than the snasw dlsw solution is almost perfect for you. If you use hpr/ip to connect upstream to the host you are all set.
In that case you dont advertise any mac addresses on the local ethernet between the snasw/dlsw routers and the osa since it is hpr/ip. Basicaly ip routing only.
From the clients perspective, they dont really know that there is a change since you replicate the old tokenring mac address as vdlc mac address/snasw port and the end systems still connect to them like they did before.
In respect to dlsw ethernet redundancy we have to be a bit carefull not to mix the scenarios.
Dlsw ethernet redundancy is designed for the branch. Not the data center.
If you use dlsw ethernet redundancy with ethernet switches, and in almost all cases today ethernet means ethernet switches, you configure a mac address mapping between artificiall local mac addresses and your real remote mac address of the host.
On each router you configure a unique local mac address. Than you point half of your end systems dmac to the local mac address configured on router1 and the other half to the local mac address configured on router2. That way you achive load balancing.
The two routers exchange their mapping and in case router1 looses the connection to router2, router1 will activate the mapping it learned from router2 aswell and then take over those circuits additional.
If you decide that you configure on router1 the local mac address equal to the remote mac address, because you have a large number of clients and can not simply change the damc's on all of them, than you need to configure a "dummy" mapping on router2 and router1 will get all the circuits in this example. router2 would be purely for redundancy in case router1 goes down.
If you think about this than it is clear why dlsw ethernet redundancy is designed for the branch. In the branch we map local to remote mac addresses and the remote mac addresses are the hosts. Typically there are only a limited number of host mac addresses to map.
If you turn this around and put dlsw ethernet redundancy on the host end than you have to map all clients. If you have only one or two clients this is certainly doable. But if you have a large nuber of clients this is simply not manageable.
thanks...

Questions about 3702i and WSM (WSSI)

I have several questions about the 3702i AP and the WSM that do not seem to be answered in the data sheets/documentation.
Any insight would be appreciated.
1. Is the WSM officially supported on the 3702 AP? The documentation seems to conflict on this.
For example, at the top of the WSM data sheet: "Flexible add-on third radio module for the Cisco Aironet 3600i or Cisco Aironet 3600e Series Access Points". Then later on in the page graphic shows the 3700 series radios too. I have found multiple pages that have similar conflicting information.
2. Can the WSM be used WITHOUT MSE and Cisco Prime? If so, are there any limitations?
3. How does the licensing work? Where is the license installed -- WLC, MSE, Prime? Do ANY of the features work without the license?
3a. How do you order the license? The SKU listed on the data sheet (L-WIPS-MM-1AP) is not a valid part number in CCW.
4. Is it possible to do sniffing with a WSM? (the idea being not having to dedicate an AP to sniffing, or taking down a client-serving AP to sniff)
Thank you.

Ok, so you are talking about off-channel scanning, which is actually a very short duration 50ms, that the AP is actually off-channel to scan.
http://mrncciew.com/2013/03/16/configuring-rrm/
Are you thinking of this bullet point?
Access points with wireless security module: The Cisco Aironet® Access Point Module for Wireless Security aggressively scans all channels without affecting the data-serving radios in the 2.4- and 5-GHz bands.
To me, that's just saying that the WSM is scanning and not interferring with the AP's normal radios.
HTH,
Steve

Adobe design question for barcodes and including PDFs

Hi all,
I am new to using Adobe LC ES 8.2. I have been reading this forum and it has been very helpful. We have certainrigid requirements for our application that is making it difficult to come up with a clean solution. I am hoping this forum will be able to answer some of my questions:
Use case: Our application needs to mail correspondence to users (printed PDFs not fillable forms). We plan to use Adobe LC ES Designer to design all the forms and Assembler Service to assemble the documents together. The plan is to merge the templates with XML business data dynamically and then assemble them. When the documents are assembled together, documents to be assembled include Cover Pages Templates, Notice Templates, Attachments (could be templates or static PDFs) and decisions that will be converted into PDF from an RTF document using Adobe Professional 8. The user creates the document in RTF and convert it into PDF using Adobe Acrobat Professional and store it for assembly process. Our Print Shop requires the entire assembled mailing to have bar codes on each of the pages with the following information:
1 D 3of9 barcode - JOB ID (can be sent dynamically) + PIECE ID (number of mailing) + SHEET ID (page number with in the PIECE ID - front and back of the page get the same number)
Following are the questions we have:
1. What ways are available to apply the bar code to the assembled document as one piece of information in the bar code is the SHEET ID for the entire mailing? I would know the total number of pages only after assembly.
2. If there is a way to manipulate the barcode information after assembly, I am not sure how we can handle bar coding the Decision PDFs that will be converted from RTF using Adobe Professional 8.
Please advice.
Thanks.

Thank you. So, using Form Services we can manipulate the document (barcode object) after assembly.This is great.I will look into this. When we spoke to Adobe, they wanted us to complete all merge prior to assembly and said we cannot manipulate the document after assembly.
How would I handle a barcode for a PDF that has been converted into PDF from a RTF document? My concern is that even if the RTF has a barcode, will it be a format that can be manipulated after it is converted into PDF by the user and submitted to the assembly process?
One of my ideas is to maybe convert this PDF into images and include it in the XML data as base64 images and merge it with an Adobe Form template having image fields. This is not a clean approach and I am very concerned about performance issues with the size of the data XML.
The other thing I am reading up about is "Underlaying pages" - http://livedocs.adobe.com/livecycle/8.2/ddxRef/wwhelp/wwhimpl/js/html/wwhelp.htm?href=0012 71.html#1548394&accessible=true
Any ideas?
Thank you so much.

How to change IP addresses of APs and WLC to the ones from different VLAN

I'm trying to figure out what is the best practice to change IP addresses on all my access points connected/managed by the WLC.
I have one WLC2504 controler and three AIR-LAP1041N access points the idea is to change management IP of the WLC from 192.168.2.100 (vlan1) to 192.168.12.100 (vlan79) and all access points accordingly:
ap1 192.168.2.101 (vlan1) to 192.168.12.101 (vlan79)
ap2 192.168.2.102 (vlan1) to 192.168.12.102 (vlan79)
ap3 192.168.2.103 (vlan1) to 192.168.12.103 (vlan79)
FYI all my APs obtain IP from DHCP server which sits in the vlan1 and each AP is connected to trunk port on Catalyst switch, trunk port (vlan1, vlan79, vlan80, vlan81, vlan82) carries traffic for different WLANs, so my question is what is the best way to change management IP on each device with the minimal downtime.
Thank you for your advice,
Luu Manioro

Well, you will have downtime anyways, but how I would do this is the following:
Make sure the WLC trunk port has vlan 79 being allowed
Change the high availability on each AP to point to the hostname of the WLC and the new ip address, you don't need the old ip address anymore
Console into the WLC or use the service port and change the management ip address and at the same time if possible, move the AP's to the new vlan 79, since they have already joined the WLC, they will know of the ip address of the WLC
Reboot the AP by shutting down the PoE port or powering off/on the AP
The AP will find the WLC since you have defined the high availability and also since the AP and WLC are on the same subnet.

Design question about instant download a patch

Hi All,
Here is a design question for you:
Background:
The application we built is being upgraded from time to time and we send it to our users.
our users use it on a network so there is only one file to upgrade (and being done by the sys admin)
We send them a �patch�; actually, it�s a new version of the application they place it in the relevant folder and continue to work with a new version.
Problems:
1. We send them the patch via email - sometimes it takes a while until they read their email and at they are using an �old version of the system�.
2. Some of them are not computer savvy (when it�s not the sys admin) and we need to guide them as where exactly to place the file (there are 3 files)
Our (conceptual never build yet) Solution:
Build a program just like Norton antivirus (or other) that prompts the user from the task bar (next to the clock) that a new version is available and by
clicking once it will automatically download the file and store it in the correct folder.
Question:
1. Did anyone try anything like this before (or something like) who can tell me about it?
2. Do you think this kind of system will work for us?
3. Does anyone have a better solution?
Thanks
Peter

thanks, I posted it there.No, he meant that Webstart is the mechanism you should use. It supports net-based distribution and automatic centralized updates of apps. Exactly what you want.
