3850 Stack Question. I'm new to stacks

So, I have two 3850's I want to put in a closet. Do I stack them or just leave them stand alones... My plan was to connect each to the core switch using fiber and users on each switch.
When I conenct the switches using the stackwise cable, I have an active and standby... Is there a way to make the standby a member? is the standby in true "standby" mode? Can I use the ports on the standby switch?
SO many questions Apppriecte any help..
Thanks

BTW, when you stack your pair, ideally, you still want an uplink from each switch. Depending on L2/L3 configuration, on both your stack and core device, you should be able to use the bandwidth from both links to/from the stack too. Also, if possible, try not to have the two links terminate on same line card on your core device, to avoid that also being a single point of failure.

Does use-new-list-stack CMD +/- work in Grid View?

With the use-new-list-stack dock setting, does CMD +/- shrink and enlarge icon sizes in Grid View? From what I can see, it seems to work in List View, but not Grid View. But I've read reports to the contrary that claim this works even in Snow Leopard. So, I'm asking.

In Lion, Command + and Command - will enlarge/reduce the displayed icons in a Dock folder set to Grid view.
I could not get the same action in Snow Leopard.

No more use-new-list-stack?

Oh boy, this one is going to hurt. The List view is thew only Dock view I can tolerate, and ever since Lion I've been implementing the use-new-list-stack option that allows items to be dragged out of List view the same way they can be from Grid and Fan view, along with allowing icon resizing and a narrower stacked hierarchy view. And it looks like the old command:
defaults write com.apple.dock use-new-list-stack -bool YES && killall Dock
is no longer working. Please tell me someone knows of another way. Not sure why it never became the default. Please.

Could you please recommend a cost effective switch that can be stacked with existing 3750X Switch(IP Base Image).And also what all modules i need to add other than stacking cable?

Do i need to order network module (C3KX-NM-1G) to stack two 3750X Switch other than stacking cable?
No. The network module, in the -X series, it to allow differ uplink ports.
What you might need to order it a stacking cable of a longer length. From Cisco, stacking cables come in three lengths. Don't know if still true, but it used to be, I believe, that a 3750 would come standard with the shortest stacking cable which is long enough to go between nearby units when physically stacked vertically together. In larger physically stacks, you would often need to order the longer cable to go between top and bottom stack units.

AS Java Stack as Add-in to ABAP Stack

We are upgrading SRM 3.0 to 5.0.
We will need to install JAVA stack as add-in to ABAP stack. SRM 5.0 need both ABAP and JAVA stack.
We have one box for DEV and QA and they are installed as separate instance (dual instance).
Can we install JAVA stack for both instance separately?
Or do we have to split the dual instancing development system into two separate standalone system
Please advise
Regards
Manisha

Hi Manisha,
If the box is properly sized I feel that in the same box itself you can have 2 java instances (just you have to take care of the instance number).
Also another point which you can consider is that whether your platform is 32 bit ot 64 bit.
So if it is 32 bit what I recommend is to use new hardware and seperate the instances.
Any how it is possible technicall to have 2 java instances in one server.

Stacks/Fan View don't update (Stack as Folder)

Hello.
After updating to 10.5.2 and setting the Stack View to Folder, my Downloads Stack doesn't update when downloading new files.
The new file is not shown but the file on top of the Fan loses their description/name. With every download/new file which should appear but doesn't, one file on top loses the name.
[This is what it looks like|http://misc.and3rs.subcoders.de/stack.jpg]
If i use Stack instead of Folder, everything works just fine.
Switching to Stack and back to Folder solves the problem for a short while but when i download more than one file, this problem occours again.
Has anybody a solution for this problem?

P.S. Didn't know that it would go down there, but in my last post I was agreeing with... Well, I can't remember their name and I can't go back to check without leaving this page, but whoever said that they were having the same problem.
P.P.S. Apple should add an "Open Previous Page in New Tab" Button. And Apple, if you're reading this, you should also consider this post.

Two questions about the new iWeb

Hi
I've got two questions about the new iWeb.
1. Is it possible to blog online now? Meaning adding a new blog entry without having to be on your own Mac? This is a feature I've been waiting for since iWeb first was released.
2. Is it possible to choose the format of images? Earlier editions had the option to "optimize" images but that meant it changed it into .png meaning the site got a lot heavier than if .jpg was used. And since I have relatives who still only have an isdn connection I need to be able to have the website as light as possible.
thanks

Ah well... thanks for the quick answer

Why can't I post a question from my new system?

Hello All:
I was just trying to post a question from my new mbp but it wouldn't allow me to do anything. It continually gave me a message highlighted in 'red' that i was;t allowed to modify or post anything. I've been asking questions for quite a while and have never seen this. I also happen to have my older bmp, also logged onto the 'Apple Discussions' site, open beside me. Can anyone explain this to me please? BTW, my new system obviously has Yosemite on it while my older bmp has Lion. Thanks in advance, to all those who respond.

ChitlinsCC, I'm adding your reloaders to my article on how to make using ASC easier.
Here is my ASC work flow...
1) I login.
2) Block the automatic 30 minute logout.
     Unless you do something every thirty minutes you get logged out. The forum software waits to tell you this as long as it can to keep you in suspense ;-) . Filling out a reply is the exception to the thirty minute window.
        Start an auto reloader.
Safari = SafariTabReloader
Firefox = ReloadEvery: "Reload web pages automatically"
Others = Reloaders | Cerberus - Support Center
You need to pick a page that will reload over time without stalling out. It's ASC. I've found my profile display the best to use. I get my Profile page after some logins. It's ASC. Change rccharles to your apple id.
https://discussions.apple.com/people/rccharles?view=discussions
Reply technique
Open a new browser window. Pick some discussion. Open a reply window. As long as this reply window is open, you will stay logged in. The 30 minute times is reset as needed by the ASC software.
3) I open another window to do my normal ASC browsing.
4) I have a FireFox bookmark to goto the discussions that I have participated in. I've modified it to add on the content stuff.
         turingtest2 recommends. Change rccharles to your apple id:
https://discussions.apple.com/people/rccharles/content?filterID=participated~obj ecttype~objecttype%5Bthread%5D
5) Use turingtest2's generated links with the /content suffix as browser bookmark to the ASC discussions:
Site map of Communities and Categories
https://discussions.apple.com/docs/DOC-2463
6) Adjust the ASC web page layout.
For FireFox
I run with Hiroto's modification to user content. This is the only way these forums are readable for me. How to adjust the format and layout of ASC Web Pages:
https://discussions.apple.com/docs/DOC-7501
For Safari
"ASCPowerTools is a Safari Extension designed to give more control"
http://www.etresoft.com/ascpowertools
7) Read and answer my old posts. I kind of memorize the time I last posted. ( It's way bad that apple eliminated the last poster to a thread. )
8) I use tabbed browsering. From a list of discussions, hold down the command key then click on the link. You get two tabs this way. The original window will keep where you have been.

PI 7.1(dual stack) and PI 7.31(Single stack) -

Friends,
I have a proxy to proxy scenario - Proxy --> PI --> Proxy
We have two servers PI 7.1(dual stack) and PI 7.31(Single stack)
i did the development in ESR and my ESR is pointing to PI 7.1, when i execute the scenario i receive one error message "receiver could not be determined", i ensured that all my input is correct, still i get the same error message.
the expectation is my scenario should point to PI 7.31, Can some one help me where and what settings i need to make in-order to make it work.
Please Note: All my data is correct and i read some scn forums wherein they asked to refresh the cache , i have refreshed the cache also still the problem persists.
Thanks in advance!

Communication component in ID is the same as sender side.
could you share your sender configuration?
Did you mean Tcode - SXMB_ADM and under that Sender/Receiver configuration
Krupa Rao Atluri
In ID steps are correctly defined.
I spoke to my colleague he hinted that at RUN TIME we want to point to PI7.31, he mentioned config change needed in SXMB_ADM
any further inputs from any one could be useful.

May be slightly simple question from a new Mac user: Why can't I quit safari? I cannot quit it from top menu bar neither to do it from dock? All other apps are working normally.

Or you can actived the right button on your magic mouse and click on they icon in the dock. then you select "stop" and it's out of your dock.

Question about the new Yoga 10 HD+

Hi
A few questions about the new Yoga 10 HD+ which I hope you can answer.
I bought the old model last year. Loved the design and long battery time but a few major issues made me return it.
Somewhere I read that it can't read NTFS over USB so I presume that's the same with an NTFS formatted microSD card?
Can it read exFAT formatted microSD cards?
Anyone observed issues regarding audio over bluetooth?
(I know BT isn't exactly High End HiFi but the old Yoga 10 for some odd reason - most likely a driver issue which nobody cared to fix - sounded *much* worse with quite noticeably distortion while both my phone and a cheap noname tablet I have zero fidelity issues - no matter which of my bluetooth audio devices I tried aptX or not)
So to avoid buying this only to return it too I really would like to see if I can have my questions answered before buying it.
While I love the form factor and long running time the above issues are just two mayor dealbreakers to me. Bad audio quality = no joy listening to spotify, local MP3s etc. No NTFS or exFAT = no large movies.
My old noname android tablet really could use an upgrade so I'm really curious whether this can be it or I should look at the competition and sacrify form factor and battery runtime.
Thanks in advance.
EDIT:
If it's not supporting either NTFS or exFAT on the microSD have anyone tried ext3 and/or ext4?
I mean with Androids Linux roots it should be a nobrainer to support at least when it comes to royalties unlike NTFS or exFAT where there *might* be some issues with Microsoft.
Solved!
Go to Solution.

Thanks!
OK. Seems I should just stay clear of this and look elsewhere
Sony for sure I know support exFAT. I'm usure about Samsung. Odd it seems so hard to find out. File sizes of +4 GB should be taken for granted - it's not 199x anymore...
Oh well. Wonder whether to just go for one from the competition or perhaps just save the money and wait until 64 bit catches on. Rumors is that the next Nexus 8 will be 64 bit... (I really don't expect an answer on this)

AS Java Stack as Add-in to ABAP Stack in case of Dual Instance

Short Text
AS Java Stack as Add-in to ABAP Stack
Long Text
Hi
We are upgrading from SRM 3.0 to 5.0.
We will need to install JAVA stack as add-in to ABAP stack. SRM 5.0
need both ABAP and JAVA stack (becuase of integrated ITS and IPC).
We have one box for DEV and QA and they are installed as separate
instance (dual instance).
Can we install JAVA stack for both instance separately?
Or do we have to split the dual instancing development system into two
separate standalone system
Please advise
Regards
Manisha

Hi Mike
Thanks for your response.
We do not have MCOD installation.
Our DEV and QA installed on same physical same server but they they their own database and separate instance of ABAP stack.
Some concern have been raised that if we install JAVA stack as add-in on DEV instance, QA instance will be impacted. Because you can not have two separate JAVA stack on same server.
Please advise if above concern is true
Regards
Manisha

Keywording stacks. Request for 'all in stack' selection.

I stacked a folder of 400 images into 12 stacks, keyworded each stack. Came back the next day, typed in a keyword - there is my stack.
But it won't expand. Stack indicator goes from '80' to '1 of 80'. I thought this was a bug .. but after eliminating the keyword, the stack expands and I see the keyword only sticks to the top copy of the stack.
If I keyword a stack, it should go through to every image. There needs to be a 'select all in stack' option. Now I have to open each stack, select photos, keyword, close stack.
A work-around is to keyword before I 'group in stack'. Maybe add a keyword to each stack (stack1, stack2) so I can actually group a stack and keyword later. Not very elegant.

You can select stack, click left side to open stack. Cmd/Ctl click last image in stack to selesct all in stack and then Keyword Stamp (show Keywrod in Toolbar) or use Keywording in Right Panel or D&D keywords.
