Memory usage per user

Hi folks, I once heard about a rule of thumb (ROT) to use when estimating how
much server memory to allocate for each end-user. Anyone remember this
amount...
Thanks...

Hi,
I recommend you run using the default which is Dynamic Fair Share Scheduling (aka Distributed Fair Share Scheduling) enabled and monitor to see if you experience problems. For details on how fair share limits per session cpu usage, please see Chapter 5 of
Windows Internals, Part 1, 6th Edition:
Windows Internals, Part 1 (6th Edition)
http://www.amazon.com/Windows-Internals-Edition-Developer-Reference/dp/0735648735
The above provides information on Server 2008 R2.  In Server 2012 fair share cpu has been improved for heavier loads and new functionality has been added to distribute network bandwidth and disk IO among sessions as well.  Precise details
on how network and disk fair share work have not been published.
Windows System Resource Manager is not available for Server 2012 R2.
You may want to consider writing your own programs to monitor/alert on resource usage per tenant and/or purchasing third party software.  Server 2012 R2 RDSH is excellent, however, it is not designed for full multi-tenancy.  If you
need strong isolation/control of each tenant in terms of security, resources, etc., then unfortunately each tenant needs to be in a separate VM.

  • System usage per user

    Hi Security Experts,
    Our company have a SAP system version ECC 5.0 and right now we are making an analysis related to the quantity of users and the quality of the system usage per user, so the question here is if there's a way to know how much resources does an user consume? this is, time connected, transactions used. This is in order to separate the occasional users from the operating users?
    I'll appreciate a lot your help.
    Best Regards,
    Erik Espinosa

    Hi
    ST03N is your solution.
    There you find every minute detail for performance in the SAP system.
    You can check User Profiles for days , weeks and months individually to check the response times, data executions from the database etc.
    You can also find the processes/ transactions that take the highest memory consumption.
    Apart from this, an earlywatch report from the system would also assist you in such an analysis.
    I hope this helps
    Regards
    CHEN

  • Solution to cap/control internet usage per user?

    On Mac OS or within Airport, is it possible to cap the internet usage of some of the users connected to an Airport netowrk? Is it easy to control the bandwidth usage or to allocate a specific amount og 'authorised' GB to download per month? Are they utilities to do that? Thanks for your answers!

    The only feature that the square 802.11b/g/n AirPort Extreme base station (AEBS) has is the ability to limit connection of specific MAC addresses to certain hours of the day. This is in AirPort Utility under "Access Control".
    The AEBS has no feature which allows you to control the bandwidth allocated to each client. Nor does it have any feature which tracks how much data a client has used.
    OS X's parental controls also offers some in the area of Internet access. You would need to visit the appropriate OS X discussion area and ask about them specifically.

  • Calculate shared_pool usage per user

    Hi,
    is there a query that shows how much of shared_pool is allocated to diffrent users? ideally showing the db user and os user or machine name etc...

  • ORA-4030  and memory usage by oracle

    I'm looking this documento on metalink:
    Note:233869.1
    Diagnosing and Resolving ORA-4030 errors
    II want to know which process is requesting too much memory.
    The document says:
    On Microsoft windows systems, oracle is implemented by using threads in a single oracle process. Up to now, i didn't find a way to view the memory usage per thread. We can however check if oracle and the operating system agree on the memory used by oracle.
    For the Operating system point of view, we can use task manager. Use the view pusbutton and select Select Columns... make sure Virtual Memory Size is selected.
    And in my system is: 1.716.712 K
    Then I execute this select to get the memory size as viewed by oracle, however, not including the process stack and code size:
    select sum(bytes)/1024/1024 Mb from
    (select bytes from v$sgastat
    union
    select value bytes from
    v$sesstat s,
    v$statname n
    where
    n.STATISTIC# = s.STATISTIC# and
    n.name = 'session pga memory'
    MB
    5711,88542
    How can it possible? 5G!

    Hi,
    It may be from the Paging space of your SYSTEM.
    If you want to know in detail.
    select details from the v$sesstat and get the session wise PGA allocated.
    I also did not understood the statement "And in my system is: 1.716.712 K"

  • Solaris 10 - Restrict memory usage

    Bonjour,
    I use Solaris 10 Release 6/06 on SPARC system.
    I need to restrict the memory usage for users.
    Unfortunately, for the moment, we can't increase the amount of RAM.
    So, in a first time, I decided to use projects and max-shm-memory. But, this is only for shared memory segment, not real memory usage.
    rcapd use SWAP instead of RAM ... it not solve my issue.
    How can limit memory usage of an user ? It's possible of Solaris 10 (without zones) ?
    Thx.
    Guillaume

    does ulimit help you? this applies to the shell rather than a user...

  • When firefox crashes from a memory leak why can't you display the offending tab? Enhancement: a task manager like tab manager showing usage per tab / extension.

    I typically keep many windows with several tabs open. It is possible that this causes more crashes since the number of pages multiplies any effect most users with less pages/tabs would experience. I have been having problems with Firefox crashing Using the windows task manager I have looked into this issue monitoring lots of variables. Bottom line the crash is caused by increasing memory usage possibly caused by the flash add on which is doing many IO reads on at least one offending page/tab. Could some sites be using flash to read from my disk without permission and there is a memory leak in either flash of the code the sites uses? I have searched the web for a task manager like add-on for Firefox tabs that would allow me to determine the offending page/tab/add-on/extension. It seems like a great idea which has not been implemented. Since I am a developer I would be happy to implement, but would like some guidance since my knowledge of your product is only at the user level.

    There is currently about:memory page which is being actively developed. A "task manager"of sorts is also in the works AFAIK. If you want to help out, your best bet is to find the applicable bug in Bugzilla. If you have the coding skills I can help get you in touch with a mentor - just let me know.

  • Amount of Resources CPU and Memory per user

    Hi,
    We are looking to deploy a Line of Business Application via RemoteApp and a custom template.  The application requires a significant amount of RAM and CPU, can someone tell me who much RAM and CPUs are allocated per session \ user?  I would expect
    that we would use the Standard tier if any difference to resources available.
    Thanks
    Giles

    Hi James,
    Currently there is no way to configure resources other than selecting either Basic or Standard.  If you would like a lower per-VM user density (and thus higher resources for each user) what you can do is create more collections, and only assign
    a small number of users to each.
    For example, say you only wanted to have a maximum of 4 users on each VM, providing typically at least 1 vCPU per user.  In this case you would create collections with the Basic plan, each linked
    to the same template image, and only assign a maximum of 4 user accounts on the user access tab of each.  Assuming each user uses 80+ hours a month, the total (before discounts) cost for each collection would be $228/month, making each user
    cost about $57/month, slightly less than equivalent cost under Standard plan pricing if you factor in resources per user.
    You probably already know this, but I will explain how scaling works normally for others that may read this.  Azure RemoteApp will automatically create more VMs for each collection as needed to handle user load (Scale-Out) and shut down VMs when the
    user load is reduced (Scale-In).  The key thing that affects this scaling mechanism is the maximum concurrent users allowed on each VM, which for Standard is 10.
    In your case you are asking if you can have more resources per user, hence my instructions above for creating multiple collections and limiting the number of assigned users to less than 10 each.
    Depending on your unique needs it may make more sense to create a custom RDS deployment on Azure IaaS VMs.  In this case you could control the size/type of VM used, user density, etc.  Downside is you have to set up and manage more
    RDS components than you do if you use Azure RemoteApp.

  • OS X Yosemite Safari memory usage

    Safari's memory usage under Yosemite continues to increase until system stalls due to paging. The memory gets to about 60G before the stall. Also, the process SafariDAVclient exhibits the same behavior. This started after I reinstalled Yosemite. Reinstalled again, no better.
    Anyone have a solution?

  • Upgrading to FF 27 created huge (~1 GB/hr) memory usage for iconified windows on Mac 10.8

    Here is what I know about the problem:
    - Two different Macs (10.8.x, 10.9.x) with 32 GB RAM ran out of system swap due to the size of the Firefox process growing to over 20 GB, and both machines had virtually idle CPUs with no Firefox usage whatsoever - they were unattended
    - It occurred immediately after upgrading from Firefox 26 to 27.0.1
    - The set of pages, tabs, windows was the same before and after upgrading
    - There does not seem to be a single identifiable URL that causes the problem, but opening a window with this URL and then iconifying it causes memory to be leaked at a substantial rate (at least on one OS X 10.8.5 machine)
    - http://msdn.microsoft.com/en-us/magazine/cc163744.aspx
    - I normally have ~25 tabs distributed across ~8 windows, all of which but one are iconified
    - Memory is consumed at the staggering rate of ~1 GB/hour while the offensive window is iconified
    - Memory is not leaked per-se - about:memory confirms that heap-unclassified memory is growing rapidly, but as soon as the offending window is opened and no longer iconified, the memory usage immediately drops back to the normal ~1 GB or so - this is also verifiable in Activity Monitor.app, etc
    - The problem occurs in safe mode, but regardless the only plugins installed are Shockwave Flash, QuickTime, and Java Applet
    - I have killed Firefox repeatedly and can recreate the same memory usage pattern
    - I have at least one Mac, however, on which trying to reproduce this does nothing
    - I've already spent hours trying to determine even the initial cause of this

    Another user was talking about this issue on the forum and created a bug report.

  • Memory usage of excel stays high after Macro is executed and excel crashes after trying to close it

    Hi,
    I'm trying to resolve an issue with an excel based tool. The macros retrieve data from an Oracle database and do calculations with the data. They also open and write into files in the same directory. The macros all run and finish the calculations. I can
    continue to use and modify the sheet. I can also close the workbook, however excel memory usage I see in the windows Task manager stays elevated.If I  close Excel it says: Excel stopped working and then it tries to recover information...
    I assume something in the macro did not finish properly and memory was not released. I would like to check what is still open (connection, stream or any other object) when I close the workbook I would like to have a list of all still used memory. Is there
    a possibility to do so.
    Here the code I'm using, its reduced to functions which open something. Functions

    Thanks Starain,
    that's what I did the last days and found that the problem is in the
    newPrice_calculate (lastRow)
    function. This function retrieves data (sets it as arrays) which was correctly pasted into the sheet, loops through all rows and does math/calendar calculations with cell values using an Add-In("Quantlib")
    Public errorMessage as String
    Sub newPrice_calculate(lastRow)
    Dim Type() As Variant
    Dim Id() As Variant
    Dim Price() As Variant
    Dim daysTo() As Variant
    Dim fx() As Variant
    Dim interest() As Variant
    Dim ObjCalend as Variant
    Dim newPrice as Variant
    On Error GoTo Catch
    interest = Sheets("SQL_DATA").range("V2:V" & lastRow).Value
    Type = Sheets("SQL_DATA").range("L2:L" & lastRow).Value Id = Sheets("SQL_DATA").range("M2:M" & lastRow).Value Price = Sheets("SQL_DATA").range("T2:T" & lastRow).Value
    daysTo = Sheets("SQL_DATA").range("K2:K" & lastRow).Value
    fx = Sheets("SQL_DATA").range("U2:U" & lastRow).Value
    qlError = 1
    For i = 2 To lastRow
    If (i, 1) = "LG" Then
    'set something - nothing spectacular like
    interest(i, 1) = 0
    daysTo(i , 1) = 0
    Else
    adjTime = Sqr(daysTo(i, 1) / 365)
    ObjCalend(i,1) =Application.Run("qlCalendarHolidaysList", _
    "CalObj", ... , .... other input parameters)
    If IsError(ObjCalend(i,1)) Then GoTo Catch
    'other calendar calcs
    newPrice(i,1) = Application.Run( 'quantLib calcs)
    End If
    Catch:
    Select Case qlError
    Case 1
    errorMessage = errorMessage & " QuantLibXL Cal Error at: " & i & " " & vbNewLine & Err.Description
    ObjCalend(i,1) (i, 1) = "N/A"
    End Select
    Next i
    Sheets("SQL_DATA").range("AB2:AB" & lastRow).Value = newPrice
    'Sheets("SQL_DATA").range("AA2:AA" & lastRow).Value = daysTo
    ' erase and set to nothing all arrays and objects
    Erase Type
    Erase id
    Erase Price
    Set newPrice = Nothing
    Is there a possibility to clean everything in:
    Private Sub Workbook_BeforeClose(Cancel As Boolean)
    End Sub
    Thanks in advance

    Reading system memory usage in Activity Monitor
    Memory Management in Mac OS X
    Performance Guidelines- Memory Management in Mac OS X
    A detailed look at memory usage in OS X
    Understanding top output in the Terminal
    The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.

  • Memory Usage.

    Good day to you all,
    Im using the miracl library for my program(www.shamus.ie). it is a c/c++ library
    I compiled its dll and made it run on windows.
    i also compiled it on linux but i didnt use the exact source codes because there are differences in compiling in linux.
    my problem is that memory usage on windows is 4mb per client while on linux, it is 23mb per client.
    Is it because i compiled the linux version wrong?
    should windows memory usage be way lower than linux memory usage?
    should i run my app on a linux or windows?
    Is JNI really faster on windows?
    Thanks

  • Memory Usage And Hard Drive Activity Increase After Latest Upgrade

    I have upgraded to Firefox 3.6.15 and latest Adobe Flash Player. Then i noticed that plugin-container started to take a lot of memory as much as Firefox itself totaling around 600Mb. Then i see hard drive activity intermittently slowing down my laptop and making it unresponsive for a short period of time. I have 50 tabs open. I have disabled Flash and since then plugin-container takes very little memory and i don't see consistent hard drive activity.
    I need Flash and i don't want to disable it. Is there a solution to this?

    I am seeking solutions for same problem.  When playing simple online games such as solitaire my memory usage for the plug in container is 300-600 mb while FireFox may only be 80-120 (with several windows or tabs open of mostly text pages). If I disable Adobe add-ons memory usage is greatly reduced. If I understood correctly it is possible to disable the plugin container and run adobe via the old method and another user thought that would solve the problem. I do not understand how it would make a difference but if you havent found a solution you may want to try it.  See these 2 threads in the Mozilla forum:
    A question and brief  explanation  and   how to disable plugin container in config
    I've previously had problems with Adobe crashing Firefox . At least now with Adobe being in the plugin container Firefox does not crash along with it.
    I have another issue - I can sometimes still hear the music from a game after I have exited the game and closed the window. I would like to know how to release the resources used by Adobe - kind of like FireFox's RamBack.
    Well, good luck to you (and me!)
