OCMS Server hardware config

Hi,
I am using OCMS Server to cater 100 K users. I have identified the below configuration. It wud be great if someone can have a look at this and advice if the resource is adequate to cater the need.
BL460c G5 Blades (two 2.66 GHz Quad-Core Intel® Xeon™ processors, 10GB memory/core, 2 x 146 GB SAS HDD)
Kind Regards,

Dennis,
Several thousand, say 3000 per hour is less than one a second. I'm not sure how much data you have (define large), but in general I'd try to keep all, or most of the data in RAM to get the best performance possible. A Linux box with say, 512GB of RAM is entirely resonable to use. If your seach patter is geographicly time sensitive (moves based on time of day), you could also effectively use partition prunning to reduce the amount of data to be searched.
This is will give you a single, fast, db. For HA you need at least two, depending on what you define HA as.

  • Care to share your server/hardware config for Spatial?

    Hi there - we're in the early stages of planning for a new spatial system (geocoding a large volume of existing address data), and we'd like to get a sense of what different organisations might be using by way of server architecture for a high-availability, large volume dataset GIS where your typical spatial query is a within-polygon or buffer-type search of geocoded address data, and you might need to support several thousand of these per hour... (for example).
    Would you share your platform/CPU/OS/memory/storage config comments as they relate to a dedicated Oracle Spatial 10g DBMS?
    Or perhaps just suggest what you had to do in addition to the baseline 10gDBMS requirements to give Spatial room to perform well...
    Any comments are accepted with humble thanks.
    Kind regards

  • Move Adobe Connect 7.5 to new server hardware

    What is the process for moving Adobe Connect to new server hardware. We are currently running Adobe Connect Pro 7.5 (7.5.1.0.100) on a Win2K3 SP2 server. We would like to move Connect over to new server hardware running Win2K8 R2 (64-bit). The Connect database will remain on a separate Win2K3 SP2 / SQL 2005 sp4 server.
    Unless it will pose a problem, the NETBIOS computer name will be different. However, the IP address and FQDN will remain the same.
    What is the recommended procedure for doing this?
    PS - Shortly after moving to new hardware, we plan to upgrade to Connect 8. Is it better to upgrade first, then move to new hardware? Or vice-versa?

    Hi,
    moving to new hardware is basically a new install on the new server, then moving over backed up content, then reconnecting to the database.
    It makes no difference if you upgrade first and then move hardware or move first and then upgrade. I'd move first and make sure Connect works fine on the new hardware, then upgrade.
    Here are some steps that should work.
    1. make sure your new hardware, OS and SQL Server are supported
         http://help.adobe.com/en_US/connect/8.0/installconfigure/connect_8_install.pdf
        (for 7.5 check the requirements here: http://www.adobe.com/products/acrobatconnectpro/systemreqs/#proserver )
    2. Take a backup of your current content directory and all customised config files.
        (the config files will be a reference to restore SSL or other modifications, do not just move them back in once upgraded).
    3. Take a backup of your database and make sure you know the login and password to your SQL server.
    4. Stop the services on the old server
    5. If also moving DB, attach your DB backup to the new SQL host.
    6. Install Connect on the new hardware.
    7. Do not start the services yet, first restore the backed up content.
    8. start the services, bring up the console and connect to the DB.
    9. check your settings in the console, a restart might be required first.
    10. Does the login page load?
    11. Follow the install guide from step 1 to re-apply SSL config if required (in Connect 8 this is done slightly different than in C7)
    Changing the windows machine name, can cause trouble, not always, but it's easiest to just re-use the name on the new hardware.
    If that's not an option, an entry in the conenct DB needs to be updated:
    http://kb2.adobe.com/cps/407/kb407446.html
    I am fairly certain these steps will work, but cannot test this and I do not know your exact environment, so I can give no guarantee this will work. It is always good to just test the move to new hardware and if things go wrong, bring the old system back into production and contact support.
    Good luck!

  • Recommended Hardware Config for huge OLAP Cube build

    Hi David ,
    Can you please provide the recommended hardware config for cube having billions of data under fact table . We ran a cube with 0.1 billion of data took around 7 hours to process. What could be the key areas to gain the performance benefit ? ansd also what could be the CPU , RAM (server) , RAM (Oracle DB) to gain much more perf benefit in such configurations ?
    Also we have 32 bit windows 2003 server .Can we get better result if we switch to 64 bit ?
    Thanks in advance,
    DxP.

    Hi!
    Well, I would definitely recommend you to proceed with a consultant because I feel that you have some lack of methodology and experience together with time constraints for your project.
    Regarding hardware, unfortunately, I would not be able to give you any precise figures because I have no supporting information. What you should bear in mind that your system must be balanced. You (better with consultant) need to find a right balance between all the factors you consider as important while building a pile of hardware:
    - cost
    - architecture
    - speed
    - availability
    - load scenarios
    etc...
    Regarding architecture point bear in mind that today finding right balance between processing power and storage processing capacity is a challenge. Put attention to this.

  • Mac mini server: Hardware test error on Hard Drive

    Mac mini server: Hardware test error on Hard Drive
    'checking for slow read failures': ERROR - Target device access failure - Test failed.
    CAN I ACCESS HD (which is our data server) EVER AGAIN? IF SO, HOW?
    Meanwhile we wonder if this is really a hardware error. It all happened during writing a time machine backup.
    Probably while writing it, some data was relocated by accident, but we can not 100%-sure remember the sequence of actions :/
    This is our trauma history:
    - time machine got increasingly slower in writing a backup
    - we quit the backup
    - we switched off the mac mini (on power button)
    - we switched on the mac mini
    - we stopped time machine to the rules
    - we shut down mac mini via command
    - we booted the mac mini in save mode
    - we see a loading bar
    - no progress after 10th of loading bar
    - switched off (power button)
    - when we now switch on the loading bar below the apple-logo is all we see + the little wheel
    - we started with cmd+alt+p+r pressed
    - mac mini restarted but showed the loading bar scenario without progress again
    - we started with 'd' pressed and did the hardware test (see above)
    - we started with 'alt' pressed but it does not give us the recoverydrive to run the last backup
    ANY IDEAS?
    IS IT A SOFTWARE- OR HARDWARE ERROR?
    THX IN ADVANCE!

    Is Temperature Monitor an app or a device?  If it's a temperature problem then that is essentially a design problem.  Two drive failures in the same Mac mini server in four months combined with the fact that they're not really user serviceable already has me 90% on the way back to more pragmatically designed Linux servers.  I think it would be foolish to waste any more money on these minis for my business hosting.

  • Error 10401 occurred at AI Hardware Config, when using AI Acquire Waveform vi

    That error code is generally seen when something has changed in the DAQ card's configuration, or the drivers are not installed properly. It's strange that this is showing up only on certain functions for your application.

  • I'm trying to timestamp (RFC 3161) a pdf using my own timestamp server hardware but always get an error: "Certificate invalid for use" ...

    I'm trying to timestamp (RFC 3161) a pdf using my own timestamp server hardware but always get an error: "Certificate invalid for use" (Original text - pt_BR:O certificado não é válido para uso). How can I get more info on what I'm missing or whats wrong with the certificate?

    Which Acrobat version are you using? Do you use "Document Timestamp" command? If so, do you get this error during the signing process and the signature is not created or signature is created and you get this error when it is validated? If the latter you can open signature properties, click on the "Advanced Properties" and in the next dialog on timestamp's "Show Certificate". If you get this error during the signing process do you get an alert that shows some cryptic info with a number? If you do provide the content of this alert.
    Also which Acrobat version (including minor) are you using?

  • How to check server hardware and OS issue without offline DB server

    Hi Experts,
    For checking hardware issue, do we have any way to check server hardware and OS performance without offline server?
    any way we could rule out bad hardware causing the problem without offline server?
    Thanks
    Jim

    I think your answer depends on the nature of the hardware issue you think you may be having, whose hardware you have, and the OS your are running on that hardware. Such as on UNIX there are several error logs that record errors related to the system including detected hardware issues and you have numerous utilities like vmstat and iostat that can be used to measure performance. Some disk units linclude their own diagnostics modules you can run.
    If you really want help I think you have to be a lot more specific about the problem you are facing.

  • How AI Hardware Config.vi into Acquire&Proc N Scans - Trig.vi amplify gain?

    I am using Acquire&Proc N Scan - Trig.vi program. I tried using AI Hardware Config.vi to add into the block diagram so as to increase the ECG waveform gain but it seems useless. How can it be done to amplify the gain of the waveform. Thanks for the help.
    Attachments:
    Scan_Trigger.vi ‏130 KB

    If you aren't using virtual channels...
    Using the original Acquire&Proc example program, you can set the gain by putting values into the Input Limits. Labview will automatically scale the results. So if your signal is 0-10V, put 0 as the minimum limit, and 10 as the maximum limit. Typically, you''ll use the range of whatever signal you're measuring, but if a higher gain is needed, use a smaller range (liek 0-1V).

  • Server hardware confusion with 32 bit and 64 bit

    Hi,
    I am very new to this oracle, and I have a doubt which is very stupid, please help me out here, I have been working for installing Retail, so I have to integrate the EBS with Retail, which I got the documents for, there it says we need OEL x86_64..
    My questions are
    1. Can we install OEL x86_64 in 32 bit server hardware?
    2. If we can install it, can we install 32-bit EBS staged files in that OS
    3. Also do I need 64 bit server hardware in order to achieve my goal?
    4. Also can anyone suggest good links for finding server hardware’s where can I look into building just for EBS single node..
    Thanks in advance
    Love this Forum and your helps that you all given me so far.. :-)

    Hi,
    AFAIK:
    1. Can we install OEL x86_64 in 32 bit server hardware? No, you cannot.
    2. If we can install it, can we install 32-bit EBS staged files in that OSYou can Install 32-bit of software's on 64-bit machines, but you cannot Install 64-bit software's on 32-bit machines.
    Although, its not recommended to Install 32-bit software's on 64-bit machines. Install sw same as Hw architecture.
    3. Also do I need 64 bit server hardware in order to achieve my goal?Check with oracle there should be 32-bit software available for this.
    4. Also can anyone suggest good links for finding server hardware’s where can I look into building just for EBS single node..http://www.oracle.com

  • Need Server Hardware Configuration Advice

    Good morning!
    We are using Microsoft Visual SourceSafe for version control.
    Two years ago, when I requested that RoboHelp be connected to a
    database application for version control and multi-author support
    (I asked for RoboSource Control on a dedicated server), they gave
    us SourceSafe on a shared server. We now have 40 help systems and
    have suffered many losses (corrupt database = rebuild the project
    using the html files) as that shared server has gone down while
    RoboHelp was connected to it.
    I'm submitting a work request to our IT department today for:
    1) Upgrade from RoboHelp Office 5 to RoboHelp 6
    2) Purchase and installation of RoboHelp Server 6
    3) Purchase of a dedicated server
    I'm stuck on what to ask for with respect to the server
    hardware configuration - and afraid that if I don't provide them
    with detailed specifications that they'll provide us with another
    inadequate setup. We currently have a need for 13 simultaneous
    authors - some over VPN - to work under version control, and we're
    growing. Can anyone provide me with a recommendation for server
    hardware configuration?
    Adobe's web site only specifies the system requirements for
    the RoboHelp Server 6 software installation - and sales support
    told me that they are not able to recommend a server configuration.
    I don't like going into this at the mercy of anyone in our IT
    department! My husband, who is a database administrator, gave me
    the following advice and I'm wondering if that's all I need to tell
    IT or are there other potential issues I need to cover?
    quote:
    For the storage or “hard drive” you want a RAID
    controller with an array of hard drives for your data. You will
    have a C: drive for the OS but your data should be separated from
    the OS on a RAID controller with an array of hard drives.
    For RAM you want a few gigs.
    In addition to the application software
    requirement of 100 MB of hard drive space, we currently have 42GB
    (2.5 years) of help system data. We have 40 help systems spread
    between 10 databases (separated by lines of business) - we used
    this configuration because early in the game we thought our
    corruption issues were stemming from databases that were too large
    for SourceSafe to handle. I'm wondering, with RoboHelp Server 6
    will we need to use multiple databases or can it handle 40+ help
    systems in one database?
    I also have a need for a few help systems to be in their own
    databases because we are running them for other companies owned by
    the bank and that data can't be co-mingled - can RoboHelp Server 6
    handle multiple databases?
    Thanks in advance for any assistance you can provide.

    Hi THessler
    I've used Microsoft Visual Source Safe (VSS) quite
    successfully for many years with RoboHelp with no issues such as
    you are citing. You further state something I and probably many
    others here find very disturbing.
    You said:
    We now have 40 help systems and have suffered many losses
    (corrupt database = rebuild the project using the html files) as
    that shared server has gone down while RoboHelp was connected to
    it.
    This would seem to imply that you aren't using RoboHelp
    correctly with the source control system. And if this proves to be
    true, you will likely see the SAME behavior with RoboSource Control
    or any other source control system you decide to use.
    Please allow me to explain. RoboHelp does not like working in
    any form of a networked situation, period. If you use it this way,
    it will frequently crash and corrupt files and all sorts of ill
    mannered things. Bottom line is that RoboHelp absolutely needs to
    be working on files only when they are stored on your local PC.
    I know I know, how does one accomplish this with a Source
    Control system? After all, the fact the Source Control system has
    to sit on a server means working from a server, no?
    Here's the deal. With any Source Control system you use, you
    should find that you have the main Source Control database, which
    resides on a server.
    But (and here's the kicker) when you configure users that
    participate in Source Control, each user is configured with
    something called a
    Working folder. This is a special folder where the files
    from the database are copied to. RoboHelp should be working on
    files inside this folder. As they are updated, copies are placed on
    the server copy.
    Sooo, before abandoning VSS or before totally configuring the
    new source control system, I'd first ensure you are using it
    properly. You may just find that you don't need to spend the money
    for a new source control system after all.
    Cheers... Rick

  • Forms and Reports 11g server hardware..

    We're looking to move from 6i to 11g F&R..
    But cannot find any docs anywhere that will help us to size the F&R 11g server hardware.
    Could anyone please point us in the right direction?
    many thanks

    We are in the midst of moving our application from forms 6i c/s to forms 11g web. I have the entire stack installed on a Pentium4 3.2Ghz 4GB DDR RAM server (its a 1U rackmount) and it actually works, although rather slowly (its for development) and only has at max 5 users on it.
    Here is the products I have installed:
    Windows Server 2003R2 32bit
    Database 11g (for metadata repository)
    Weblogic 10.3.1
    OID 11g
    SSO 10.4.3
    PFRD 11g (services and developer)
    It uses all available RAM and the Pagefile to disk is 6.03GB
    We have implemented the stack on a customer's server which is a modern quad-core Xeon with 4 GB RAM with SATA drives, and it is much snappier. Still 32bit Windows 2003R2, thought.
    We are about to try out a new server running on Windows 2003R2 64 bit with 8GB RAM to see how it performs. The database/weblogic/OID/PFRD combined is such a memory hog.......

  • Can I install Snow Leopard on Mac Mini Server hardware?

    What I would like to do is buy the Mac Mini Server but I don't need the server OS. I want the desktop OS on the Mac Mini Server. Will installing Snow Leopard on the server hardware be just like installing it on a regular Mac Mini?
    Or should I just wait and see how Lion shakes out?

    Thanks Indy, I already had proceeded the installation according your tip. Just an objection related to the updates: I was able to install the OS updates only while in target mode, as when I made 2 attempts to update the version 10.6.6 to the current one (10.6.7 - the combo one and the MBP version too) it was not permitted. I had to plug the FW cable into the MBP again and update the Mini's OS (using the special MBP version of 10.6.7) in target disc mode. I want to use the Mini as a media server and intend to install Windows 7 on the other HD which now hosts the server OS. However, according to one poster (Sven G) there are some problems (I don't know exactly what they are) related to Boot Camp software. Have you any information about these problems?
    I have maintained both OS (standard and server) living side by side on the Mini, is there any problem with that?
    Again many thanks, you were succinct, right to the point, and your tip just proved itself correct. 
    Cheers

  • Migrating server hardware replacement oes11 to oes11sp2

    This summer I will be replacing server hardware at one of my schools. Currently it has sles11sp1 / oes11 -- put in in 2012. The patches are up to date for this version, but I have not upgraded/migrated it to a newer version yet. I have played in a test environment with the yast2 wagon migration from sles11sp1/oes11 to sles11sp2/oes11sp1 -- no problems. However trying to find notes on how to do a migration and identity transfer from source server hardware to new target server hardware. Found oes11sp2 migration tool administration guide. I haven't found anything telling me how to setup sles on the target server box ie server name etc. Once I have the target sles server setup, I realize I need to install OES and select the "Novell pre-migration server" option during this installation.
    Current source server = sles11sp1/oes11 and has iPrint, Nss and netstorage installed. Installed in tree with oes11 and oes11sp1 servers.
    The main tree server has sles11sp2/oes11sp1 on it. We will need to upgrade it to sles11sp3/oes11sp2 this summer. I'm fine with doing the yast2 wagon migration on that server. We just haven't done server hardware replacements for OES-L yet.
    Looking for some good (step by step) instructions. ;-)
    Thanks
    Patty

    Originally Posted by amdsbnovell

Then install oes11sp2 into the tree in a temporary location in the tree as a premigration server (for the installation). Then I should be able to follow the instructions. When I do the identity transfer, I'm assuming it renames the sles11sp3 server from tempfs to testfs as well (as that is where oes gets the file server name from)?
    Um, sorta. Let's pretend your server name is: OLD and the new one is NEW (temporary NEW name and temporary NEW IP)
    OLD: OES11
    NEW: OES11 SP2 (assuming you want latest stuff).
    Do all your data transfer/consolidations/etc
    Then when you do the ID transfer, it will literally transfer the eDir databases (well copy is more correct) from OLD to NEW, you shut off OLD, I think it restarts NEW and renames/changes the servername and IP to what OLD had.
    You can choose to install the NEW server with the .ISO separately (ie: Install SLES11 SP3, then after you're done, Add On the OES11 SP2 .ISO), or you may choose to use the integrated DVD and do it all at once, or use the 2 separate ISO and do them at once (but depending upon your installation method, you may not be able to do the 2 separate ISO).
    I hope that helps.
    I'm about halfway through editing my docs for OES11 SP1 (of course, SP2 is out now) for migrations from OES2 SP3, but the same setup steps basically apply. I think the only things that changed from NW To OES (ie: OES2 to OES11) are DHCP and iPrint migration procedures.
