Exchange liscences, per mailbox or per concurrent connections

can anyone confirm, ideally with evidence via a microsoft link, as to whether exchange 2010 server client access liscences are per user, or per mailbox, i.e. if you have 300 mailboxes, you need 300 cals, whereas if you only have 150 concurrent connections
to the mailbox server at any one time, you only need 150 cals.
Also if its per mailbox, what are the rules on ex employee mailboxes, that are sat on the mailbox server, but not being actively accessed. Do they still require a CAL, or can they be flagged as disconnected or something?

Hi,
A user with multiple mailboxes requires only one CAL. In contrast, if multiple users access the same mailbox, each user needs his or her own CAL, unless the user is accessing that mailbox from a single device licensed with a Device CAL.
A better explanation is provided here:

Trying to determine costs per concurrent user

I have tried to investigate the services and theirs costs as well as I can and tried to get help. However I have very little experience with hosting and databases so after all this research I'm left with a bunch of questions.
Forgive me if this is too many for this kind of forum, if so, could you please refer me to where I can learn more?
We're developing a multiplayer browser game in Unity3D. The game will communicate with a SQL database. I'm trying to determine how much it will cost me per Monthly Active User (MAU) and per Concurrent User (CCU). To do so I need some things clarified. In order
to determine which feature will be the most limiting and therefore define which performance level I need.
They will on average communicate with the database app. two times a minute (defined as two queries per minute). Does this mean that I need a transaction rate of at least two per CCU?
How fast can you open and close a session? I'm trying to figure out whether I need to have one session open constantly per user connected to the game. If so, I suppose max sessions would be equal to CCU?
If I need more CCU than one database of a given performance level supports can I then just subscribe for more databases which will then automatically become copies of one another and you will divide users between the databases automatically?
As I understand your description of your database services through Basic, Standard and Premium, the database will be able to work independently of additional webhosting. However then I do not understand why there is no info in regards to bandwith limitations.
Do I need your webhosting services along with subscribing for the database? Then I suppose the bandwith limitations of the webhosting applies for the database as well?
In regards to the webhosting, besides for maybe handling the database, the website's by far most demanding service will be to allow users to download a game of max 30 MB. How can I estimate how many users will be able to download simoultaneously from a given
VM instance, e.g. basic 1?
If the database depends on this website for communication to the game, how can I then estimate how demanding that will be to the power of a given VM instance?
I realise that some of these questions may be difficult to give precise answers to but any help with getting closer to an answer is highly appreciated.

This is by no means accurate and complete, but will give you an idea about how to go about doing estimates:
First you need to know what database tier you need: basic, standard or premium.
The tier you need depends on the processing power you need, and directly relates to the number of concurrent users you have at any given time and the processing requirement of the database.
You can determine this only after you do some benchmarking of your app.
Supposed you have 100 users and you need basic tier S0, then cost per user will be (cost for S0)/100.
Then you need cost for your web service/site.
Again you need to know how powerful it needs to be.
You can determine this only after you do some benchmarking of your app.
Again supposed you need a A3 then cost per user will be (cost of A3)/100.
Then you need cost for data transfer from your web service to your user.
Supposed every data transfer is 10K, then you have 20K/min.
Supposed a user stays in your game for an hour, then you have 1.2M/user/session.
Supposed the user plays 10 times/month, then you have 12M/user per month. Then you can calculate the cost per user.
I suppose you can safely assume that bandwidth is not a limitation in Azure for your app for the moment.

Currencies Exchange rate per Customer

Hi Experts,
Is there anyway in SAP to maintain Currencies Exchange rate per Customer. For e.g. the customer's currency is EUR and my local currency is USD.
Meaning we want to maintain a fixed exchange rate for that particular customer, so during creation of Sales Order, system take this fixed rate instead of taking FI - Currencies Exchange Rate table.
Thanks,
Kiran D

Hi Kiran,
Just check the Currency field available in the customer master Sales Area Data --> Sales tab. The currency maintained in this field is determined in Sales order.
Hope it works.
REWARD if it helps you!!

Important 50K concurrent connection

Do you know if weblogic application server can handle 50K concurrent connection? I have to make the decision if it is possible to use weblogic application server to do. If so, how many servers do i need (just an estimation is ok).
Please let me know the answer

This is very true, and often overlooked. What are you using in your
application? I'm working on a project that is using EJBs, JSP, servlets, XML
and XSL and very, very dynamic content.
The xsl transforms alone were probably our biggest performance hit. We've
since moved them to an external servlet engine (Caucho's Resin) to take some
of the burden off of our WL servers, and performance, and especially
scalability, have increased immensely.
How dynamic is your application? How many queries are there going to be per
served page? What kind of transform/building of each page is necessary?
These are all factors that are going to impact your speed and scalability
long before 50k users hit your site.
Thanks,
John Stotler

BEA has people that can help you estimate the amount of hardware required.However, any estimate is very dependent on the application. Personally, I
recommend that you (with or without help from BEA) do a little stress
testing of the application to get a feel for how well it scales on a single
JVM. Once
you get a feel for this, it will be easier to get a more realisticestimate that we (BEA and you) can be comfortable with. If you want some
help with this, please talk to your BEA Account Representative about this.

How many concurrent connections can ACS handle at once?

Hi Experts,
Could you please let me know how many concurrent connections ACS can handle at once?
Is there any limitation on it?
Our ACS version is 4.0 (1) build 27.
Thanks in advance for your help and have a nice day!
Regards,
Gabor

It depends on many other factors but as far as I know ACS can handle upto 40 Auth request per second*

Kernel parameter for large concurrent connections database.

Hi,
Does any one have suggestion about kernel parameters we have to modify for large concurrent connections database (about 20000 concurrent connections) ? We would like to use Sun M8000 as our database server. Oracle installation guide indicated many parameters and values, but it seems ok for general database, not the one we need. Please somebody help us. Thanks !

I certainly don't have any idea where the 150G memory usage for 20000 concurrent users come about. That's 7.5MB per user session.
The session memory usage is depends on Oracle version, OS , Database configuration and application behavior etc..
From following query we can tell, average session memory usage is around 1.5M in normal usage on 10g linux platform.
It could go up to 20-30M if user session doing large data manipulation.

How many concurrent connections that an ACS server version 4.2 latest patch can handle?

I have about 50 routers and layer-3 switches that autheticate via tacacs+. The AAA server used to be on a Linux machine running open-source tacacs+ built by me. I have a perl script that will log into all 50 devices at the same time to collect statistics. This script is multi-threaded. Everything is working fine so far.
I recently out-sourced the AAA function to a 3rd party company, not by my choice. The 3rd party uses Cisco ACS version 4.2 with the latest patch running on Windows 2003 Enterprise Server with 16GB RAM and quad processors with quad-cores, IBM x3650-M2 hardware. The connectivity between the 3rd party and my company is through a DS-3 connection. Maximum bandwidth over this DS-3 connection is less than 10Mbps at most.
I noticed that for the past 3 months I have multiple failures with this perl script due to authentication failure with the ACS server. If I just run the script again a few routers/switches, there are no issues; however, whenever I started the script to log into 50 devices all at the same time, it will fail. If I made the configuration on all routers/switches to point back to the old open-source tacacs+ server, the issue goes away. The minute I switched back to the
new ACS server, the issue came back. If I modified the script to hit one device at a time, it works fine. I think it is the ACS server can not handle a lot
of AAA requests at the same time.
Does anyone know how many concurrent connections that an ACS 4.2, with latest patches on Windows 2003 Enterprise Server with lot of memory and CPU power, can handle? I can't seem to find this anywhere on Cisco website.
Thanks in advance.

No, Im not saying ACS cannot cope.
Concurrency and latency are very different things. ACS CSTacacs can handle many 100s of simple authentications/authorisations per second with users in the internal database. If 1000s of devices all send traffic in the same instant it would take some seconds to work through the backlog of traffic.
Also, worth considering that a limited number of tasks within ACS (or threads) can actually handle a much greater number of "logins" because they are generally multi-message allowing ACS to keep lots of plates spinning.
If users are in an external databases the latency (per authentication) can increase depending on where the users are (eg Windows AD) and if bad enough can have a serious effect on the overall authentication rate. At which point customers normally turn to load balancing.
If your device timeouts are 20 seconds (totally reasonable) I suggest the issue is more likely to be something else... a bug, perhaps specific to v4.2?

Exchange 2007 shared mailbox

How do you connect an exchange 2007 shared mailbox to your iphone? Normal "user" mailboxes work just fine. Is this supported by Apple and or Microsoft?

Hi
You can not control this behaviour from Exchange. This is controlled by Outlook.
Outlook chooses the from address from what additional mailbox you are replying from (just as you see :-))
There are a lot of registry tweaks for Outlook, but I don't think there are one to control this.
I see 3 possible sollutions.
1. The users can choose them self
2. You give the users "Send As" permissions on the mailbox
3. you use this tool

Hi,
The above error may occur when the federated built-in e-mail account that links to the computer account no longer exists or the federated built-in e-mail account in the Active Directory service is corrupted.
I recommend you follow the steps below for troubleshooting:
1. Remove the FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042 e-mail account by using the ADSIEdit tool.
a. Run adsiedit.msc.
b. Locate the Default Naming Context node, and then locate to the CN=Users container.
c. Locate and then right-click the CN=FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042 container. Then, click Delete.
2.Rerun the Exchange Server 2010 Mailbox role setup application.
3.Create a new federated e-mail account by using the following cmdlet:
New-Mailbox -Arbitration -Name FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042 -UserPrincipalName
FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042@<Default_Accepted_Domain>
Hope it helps.

Exchange 2010 - New-Mailbox - A positional parameter cannot be found that accepts argument '-PrimarySmtpAddress'.

Hi,
I am currently writing a powershell script that utilizes the new-mailbox command of EMS to create a shared mailbox.
I am connecting to EMS via a remote PSSession object.
When I try and specify an alternative SMTP address via the -PrimarySmtpAddress paramater I get the error
" A positional parameter cannot be found that accepts argument '-PrimarySmtpAddress'.
I have confirmed that the version of Exchange 2010 installed on the server should have this parameter - Version 14.3 (Build 123.4)
An example command :-
New-Mailbox -Shared -Name "SharedMailbox_test" -Alias "testsharedmailbox" -DisplayName "SharedMailbox_test" -UserPrincipalName "[email protected]" -OrganizationalUnit "OU=Mailboxes,OU=Accounts,DC=domain,DC=com"
-Database "DB1" -PrimarySmtpAddress "[email protected]" -force
Has anyone else experienced this behavior?
Steve.
Just a good old boy, never meaning no harm

Hi Rich,
That was my initial thought too, so I triple-checked my command to see if it was a simple syntax error - it wasn't.
On further investigation I compared the list of parameters available in a DEV EMS session (on where I know the command works) against the one in PROD where the problem occurs. Both sessions are running the same version of EMS.
I ran the following to get a list of parameter names in both sessions :-
$a = gcm New-Mailbox
$a.Parameters.Keys | sort
Here's the results :-

It might be a permissions-based issue, but I don't own either EMS session so can't test personally.
I will keep investigating and update here once I have some further information.

Max concurrent connections

Coming back to a topic that was posted a few months ago with
an
additional question:
>I believe you mean to ask, "What is the maximum number of
>concurrent connections such as those used in loadMovie or
XML.load?"
>If this is what you're asking then there are no current
limits. However,
>the sending server may limit concurrent connections for a
single client
>to any number so the loads may fail if they exceed this
limit. The
>limitations are therefore server-based, not Flash based,
and they will
>differ from server to server.
My question:
While Flash doesn't enforce a limit, do any/all browsers
enforce
limits? If I wanted to load up 50, 100, 200 movies at once,
where if
anywhere would I be limited?
Also, it seems that, in a test program loading a bunch of
images from a server concurrently, I am not able to get more than
two at once. Is this purely a server issue?
-andy

Hi,
I imagine it does.
Also I guess if we are talking about just some random UDP traffic it would also mean that the default timeout for a connection would be 2min. The most usual UDP traffic would probably be DNS querys. In those cases I presume though that the UDP connections dont stay on firewall for long as long as the firewall sees the DNS reply.
But as I said if we are talking about some random UDP traffic that is allowed through the firewall I would guess it stays in the connection table of the firewall for a couple of minutes. So you might be looking at 1000 concurrent connections or even more?
I have once witnessed a single server sending so much UDP traffic that it reached the connection limit of an ASA5540 which is 400 000 concurrent connections.

Sender of the voice mail is on the Exchange 2013 and receiver of the voice mail is on Exchange 2010
Is this not supported scenario of Exchange 2013 UM server and Exchange 2010 mailbox server

You cannot and should not expect Exchange 2013 UM function for mailboxes housed in Exchange 2010. And the reverse is true as well. If you want Exchange 2013 UM to function for users, their mailboxes need to be in Exchange 2013. Exchange
2013 UM should be able to redirect calls to an Exchange 2010 UM server if it detected a call was destined for a mailbox being hosted by Exchange 2010, assuming the UM servers/roles/services are within the same UM Dial Plan.

ASA max concurrent connections

If I have a thousand nodes from the public each perform a UDP ping to a server behind the ASA, does each count as a concurrent connection?

Hi,
I imagine it does.
Also I guess if we are talking about just some random UDP traffic it would also mean that the default timeout for a connection would be 2min. The most usual UDP traffic would probably be DNS querys. In those cases I presume though that the UDP connections dont stay on firewall for long as long as the firewall sees the DNS reply.
But as I said if we are talking about some random UDP traffic that is allowed through the firewall I would guess it stays in the connection table of the firewall for a couple of minutes. So you might be looking at 1000 concurrent connections or even more?
I have once witnessed a single server sending so much UDP traffic that it reached the connection limit of an ASA5540 which is 400 000 concurrent connections.

Max Concurrent connections supported by UTL_HTTP

Hi,
Can anyone help me out to find how many concurrent connections can UTL_HTTP.REQUEST_PIECES support. Is there any parameter that governs max no.of connections? If so, pls post the parameter name.

Assaf: as always, thanks so much for the info!
When you say double-sided, do you mean a memory stick which has chips on both sides; as in 8 chips on each side?
I bought the Kingston memory one stick of 128MB PC100/PC133 which has chips on one side. I also bought the 256MB PC100/PC133 which has chips on both sides.
I currently have both these memory sticks in the MS 6119 and they appear to be working well. I am running Prime95 torture test just to make sure everything is working as it should be.
Currently I have the following memory in the MS 6119:
Bank 0 - the original PC100 128MB stick which has 8 chips on each side.
Bank 1 - the Kingston (KVR133Q/128R) PC100/PC133 128MB with 8 chips on one side.
Bank 2 - the kingston (KVR 133Q/256R) PC100/PC133 256MB with 8 chips on both sides.
The total is, of course is 512MB - and appears to be working just fine. Windows LOVES RAM :D

Limit number of concurrent connection

is there a way for me to limit the number of concurrent
connections to the media server. my upload bandwitdh is about a meg
so having too many connections just kills the whole thing. i would
like to put a limit at 5 connections. is there a way to do
this?

well i am only using flash media server to displaying videos
and just that. the reason i went with media server vs. progressive
was fullscreen method. since flash doesn't natively support
fullscreen you have to open another browser in fullscreen with
javascript. the problem with that is it start loading from
beginning so i decided to go server that way it only has to buffer
and get to the same point without having to load the whole video up
to that point. Now i want to limit number people that can be
watching the video. if i get more that 5 connection the whole thing
slows down. i am not too familiar with server based connections so
i don't know how to limit the number concurrent connections.
