Ideal Production setup for around 5000 application users

Hi,
We are in the process of upgrading our hardware to cater about 5000 application users. Please share information on these -
a) Production server
i) Server Brand
ii) OS
iii) Database size
iv) No. of CPUs with speed
v) Physical RAM size
vi) Disc partitioning info (database disc size, swap size etc.,)
b) DR server configuration (same as above)
c) Network connection speed between application tier and db tier
Any other additional information is also appreciated.
Thanks for your help.

  • What is the Ideal Production Setup For One Admin and 4 Managed Servers

    Dear Experts
    I will be starting with production setup including one Admin server and 4 managed servers in one single domain.
    I am thinking of creating a single node environment(no clusters) as the machine has following configuration
    OS : Windows Server 2008 R2 Datacenter
    RAM : 48 GB
    System Type : 64 bit
    Processor : Intel(Xenon) 4 processors [email protected]
    Can you please let me know if this configuration would suffice for the 4 managed servers if i assign Xmx and Xms as 4096 and Heap Space as 1024 to all the Managed Servers.
    It is very urgent and i need to convey to the Infrastructure team if harware procurement is required.
    We are looking at somewhere around 300 concurrent users(maximum load) and 100(minimum load) at a given point of time.
    Please reply ASAP.
    Thanks in advance

    Heap size must be calculated according to the applications that are been deployed on each JVM.
    With no deployments, you dont need more than 256k for managed servers heap size and 512k for adminserver. As biggest its your heap size, longer will take your garbage collection. And if you can prevent it, better do it.

    Hey everyone in Apple world!
    I figured out how to fix the flashing yellow screen problem that I've been having on my MBP!  Yessssss!!!
    I found this super handy website with the golden answer: http://support.apple.com/kb/HT1379
    I followed the instructions on this page and here's what I did:
    Resetting NVRAM / PRAM
    Shut down your Mac.
    Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.
    I went through the 6 steps above twice, just to make sure I got rid of whatever stuff was holding up my bootup process.  Since I did that, my MBP boots up just like normal.  No flashing yellow screen anymore!!   
    (Note that I arrived at this solution when I first saw this page: http://support.apple.com/kb/TS2570?viewlocale=en_US)
    Let me know if this works for you!

  • Ideal hardware setup for Aperture

    Is there an ideal hardware setup for working with 18megapixel raw files in aperture? Of the three...graphics card, cpu and ram...which are the most important to processing the raw image.
    I am running 10.6.3 on a macbookpro 2.2GHz core 2 duo, 4G ram and an Nvidia card with 128Mb of vram.
    Overall it feels somewhat slow, about 10 seconds to load the full raw image on screen. Is that just to be expected? Any form of image adjustment usually switches to low res while adjustment is being made.
    Thanks in advance.

    A fast hard drive seems to be the most important thing now. The more I use Aperture, the more I appreciate the need for fast, fast hard drives! Open the activity monitor and monitor your disk activity. Monitor the IO - if you are constantly in the hundreds for the disk IO counters, you are IO bound (and more than likely it's your library database and preview thumbnails database).
    For a laptop, the Seagate 500GB with the 4 GB of flash built in that it manages might be a good way to go. I just got one and haven't had a time to put it in my Mac Book Pro for testing. If it manages to put most of your library database in the 4 GB flash cache, you won't see near the performance issues as with a regular hard drive.
    You could get a smaller SSD for your primary drive and to put the library on, then get one of the kits to remove the optical drive and put the hard drive in that bay. Reference your masters on the hard drive and that way you won't go broke buying a huge SSD. Gasp! I know, me recommending referenced files - I'm grudgingly coming around. Well, that and Aperture 3 has some pretty nice features for referenced files that are making me more willing to consider that kind of a setup, esp. when I look at the disk activity and constant fragmentation of the library and thumbnail database files. I'm seriously considering getting an SSD just for my library database and thumbnail databases and referencing the masters on my internal RAID.
    Also others have recommended iDefrag and I can heartily recommend it as well if you stick with traditional hard drives. If nothing else, download the free version and run it - I'll bet that the two aperture databases for your library will easily be the most fragmented files on your hard drive, followed by the thumbnails themselves. SSD obviously doesn't have the latency issues of rotating disk so defrag isn't needed - indeed it would just shorten the life of your SSD with a bunch of unnecessary writes. If you do consider SSD, the only one I can recommend for the Mac is from Other World Computing/MacSales as it does internal garbage collection. Until Mac OS X supports TRIM, normal SSDs that don't do internal garbage collection will run fine for a while, then hit a performance wall that will make you want to go back to your hard drive
    Anyway don't feel bad - until I started tweaking my hard drive setup, there wasn't a real speed difference between my MacBook Pro and my Mac Pro - want to talk about a real downer!

  • Example for setting up application users

    I would like to see an example application that handles the user access to that application (creat user,edit user, etc).
    I've done a few searches here and seen what appear to be various parts of this issue but I must be missing the big picture, that is a complete howto of how to do that.
    I follow the links through the messages and wind up with several windows open but no clear cut example that I've found.
    I appologize in advance if I just missed an obvious link to such an example.

    Bill,
    Just a few comments about user accounts. I may be the loudest voice against using HTML DB user accounts for full-fledged production applications, mainly because it usually means more work (one more place to reset passwords, to maintain email addresses, to let the help desk know about, etc.), less security, and less utility than an LDAP directory, especially when a Single Sign-On solution is implemented around the latter in the enterprise.
    For informal workgroup applications, development environments, one-off prototypes, all that stuff, we don't care what you use, that's why the developer accounts can be used to authenticate users into the applications that you build. Developers should take that capability as a "starter" solution, without expecting it to meet anything more than basic functional and security requirements. Hence the absence of recommendations from us about how to manage accounts; these chores are tangential to application development and there are already industrial-strength solutions available that we aren't trying to compete with.
    I hope that sheds a bit more light.
    Scott
    P.S. Thanks for showing your name.

  • Best setup for a swing application

    Hello,
    I have developed an Swing application for a EPOS machine.
    The machine has around 512 ram.
    What's the best setup for me in terms of performance, for example, which JVM to use etc.....
    Cheers

    Hi,

    ...I'm currently going through a book about Swing and read that many times the "slowness" of a Swing-application can be credited to the programmer for not using the API efficiently/correctly (letting the app repaint too much, or repainting large parts that don't need repainting at all, to name just two things). So, I don't know how much of a Swing-guru you are, but it might be better to read a few decent Swing tutorials or pick up a good Swing book.

  • SSRS How to grant BROWSE permission for reports for all the application users?

    Hello,
    Problem Statement
    I need to allow all of my application users to browse the SSRS reports via logging onto the Report Manager and to some other I even want them to use Report Builder to modify & upload the report.
    How could I achieve this.
    Environment & Current implementation
    We use SQL Server 2012 reporting services.
    Custom authentication has been implemented using IAuthenticationExtension Interface. For more details, please refer
    this msdn link.
    Currently, for each new user created in the application, the admin has to manually give BROWSER role to the username to enable that newly created user to browse the reports.
    Is there any way in which we can give "everyone" the BROWSE permission and get rid of this manual permission granting process?
    Please feel free to ask for any additional information you need to help me on this issue.
    Thanks!

    Hi vinaypugalia,
    According to your description, you want to grant permissions for users to access report server in a batch, right?
    In your scenario, you can use
    script files( AddItemSecurity.rss and ConfigureSystemProperties.rss )with the Reporting Services SOAP API to assign permissions. It’s better that you add those users to a user group then run those script.
    Similar thread for your reference:

    If you have any question, please feel free to ask.

  • Ideal drives setup for running Logic???

    Hello,
    I just purchased an internal 256GB Samsung 840 pro SSD drive. I have an external Firewire 800 2 TB external hard drive (7200 rpm) as well. What would be the ideal setup for running Logic?
    Thanks!
    2011 iMac 27", 16 GB of RAM, Logic Pro 9.1.8, OS X 10.7.5

    Thanks.
    Already talked to the tech doing the installation and he said I can stay on Lion.
    Going to get rid of the optical drive, like you suggested, and keep the internal HDD to work in conjunction with the SSD. So, I'll put my OS X and Logic on the SSD, samples on the internal HDD, and project folders on the external firewire drive. Is this what you suggest? Did I miss anything?

  • Ideal disk setup for MDFs, LDFs, TempDB, and cube files?

    I'm about to build an enterprise SQL Server that will run both OLTP and our data warehouse (OLAP).  What is the proper disk setup for data files, please?  Is it something like:
    1 for MDFs

    1 for TempDB
    1 for OLAP files

  • WVC54G setup for third party applications and also firmware query.

    I have resurrected someone's old WVC54G and installed it to work initially wirelessly to my netwark and then my Windows 7 64-bit laptop. I did an initial reset, then set up the ip address etc. to the system here, and everything seems to  work even though the viewer and recorder software installer gave a Windows error message.
    I'd like to be able to look at the camera via the VLC viewer application, and I see from another posting here that this should work.  Is there a guide anywhere showing how to do this? Ideally I'd like to understand how to interface the camera so that I can test various third party camera applications.
    Also, the Linksys setup software says the firmware version is V5.10, Feb 21, 2005, which seems a much higher number than it should be. Is this right?

    Try downloading the viewer and recorder utility from the linksys website under the download section which is pretty user friendly.
    To view it in VLC player, you can use the option 'open url' in file menu and type in http://your camera's IP
    The latest FW for wvc54g is ver. 2.11. The version you have mentioned might be software version.

  • Pre-Production Setup for Failover

    Hi
    I have installed my SAP Production environment on Window 2008 R2 , SAP ECC 6.0 EHP5, Oracle 11.2.0.3.
    I have setup my DR system at different seismatic zone  on Window 2008 R2 , SAP ECC 6.0 EHP5, Oracle 11.2.0.3.
    The Oracle Dataguard is used for data replication from Production to SAP DR system.
    Now I want to test the failover scenario. I would like to go and install the separate SAP environment in primary site as Pre-Production for DR Test on different hardware box. The system identification (SID) for production and pre-production is same as RP9.
    Would like to know that Can I use the same root domain controller (RDC) available at primary site for production and pre-production environment. The domain users are same  for both SAP systems.
    Please clarify that does this situation will create any problem to my production or pre-production environment with same root domain controller?
    or
    should I go head with different root domain controller for pre-production environment ?
    Regards
    vimal

    Hello
    It is not recommended to have SAP systems sharing the same SID in a landscape... at least because it is not possible to have the system in the same TMS transport domain (but this can also have other drawback, especially if both system have client with same logical system name).
    Even if it is possible to use the same domain users for two different systems I would not  recommend this option, especially if one of the systems is a production one...
    Suppose that for any reason the SAP domains accounts gets locked / modified / deleted ...
    Either you create pre-prod system with a different SID (best option) and then you can share the same windows domain, or if you are willing to keep the same SID I would suggest that you install your pre-prod system either in an other domain or in a workgroup...
    If your purpose is to test your Oracle DR abilities that is not a domain related mechanism, so you can test it in a workgroup...

    Hi,
    Consider the above scenario,I suggest you to use the SQL Server Compact+ ClickOnce Deployment, A Compact SQL database is a file that can be bundled with your application installation. Below is a link guiding you through the creation process of a SQL Compact
    database.
    http://technet.microsoft.com/en-us/library/ms173009.aspx
    The following link discusses setting up the necessary dependencies and prerequisites for SQL Server Compact. (Note, you will need to scroll to the section entitled Private File–Based Deployment.)
    http://msdn.microsoft.com/en-us/library/aa983326(v=VS.100).aspx
    A ClickOnce Deployment can help you publish your application attach compact SQL database into client machine.

  • Mac Pro ideal HD setup  for Logic?

    Hey  guys - just want to ask suggestions for the ideal hard drive set up for using logic.
    I have a dual quad 2.8 mac pro with 10gb of ram. External sound card is usally a line 6 ux1,  but when im recording vocals or anything miked up it's
    my focusrite saffire pro 40.
    I have 4 internal drives:
    1. boot up drive is 240gb SSD,
    2. "tracking" drive,
    3. "loops" drive,
    4. personal data drive - pics, docs, movies, music, etc....
    So i was told many years ago (when i had a imac) that the idea drive set up was to have a boot/apps drive, tracking drive, & loops drive.
    I've done that but im not sure how to get logic to work like that. Even though my projects are all stored on the tracking drive,
    the loops end up there too...
    Is it ok like that or can someone suggest an alternative? Im using logic studio 8 btw
    thanks in advance
    Mal

    I have a Mac Pro 2*2.26 system. I use Logic and iPhoto extensively with a 200 GB iTunes collection and a 80 GB iPhoto collection.
    I use the default 640GB drive as my boot drive with applications. I use a second 1 Terrabyte drive as my "Home Directory" for documents (iPhoto library, iTunes library, Logic files, etc...). I use a third Terrabyte drive for my Time Machine backups. All are internal drives.
    Given you have over a terrabyte of data files, it would seem logical to keep the boot drive for system files and applications. For your documents or "Home Directory" it would seem a 1.5 or 2 terrrabyte drive is in order, with a third 2 terrabyte drive for your Time Machine backups.
    I don't think a RAID configuration would be of benefit to you if you are not finding performance issues with Final Cut Express.
