Minimum Supported Configuration -Swap space

Hi Guys,
Just wanted to check on the swap space usage requirements for a sunray..
It says: Disk Space: 95 MB for installation; 50-100 MB per-user swap space on http://www.sun.com/software/sunray/techspecs.jsp
Does that mean every sunray user will need 50-100MB swap space on Sun Ray Server per user connecting through Windows Connector / VDA connector??

Every user will need some additional amount of swap space. The 50-100MB number on that page is just an estimate, a typical average. If all of your users run memory-greedy applications in a local desktop on the Sun Ray server then you'll probably need more than that. If your users run only a few lightweight applications with no local desktop then you'll probably need less than that. If your users will be using only the Windows Connector or VDA Connector then those are lightweight compared to a full desktop plus desktop apps, so the swap requirement should be pretty small.
If you want real-world numbers then you could ask the people on the sunray-users mailing list (see http://www.filibeto.org/mailman/listinfo/sunray-users) to share the swap numbers that they're seeing in deployments like the one you're planning.

  • Swap space

    Hi
    I intend to install oracle 10 R2 on redhat linux 5 , my system have 64 gb ram
    how much swap space i need to setup for this size of ram
    i check some installation docoment it mention
    if the memory is 1 to 8 gig then it should be double
    if it is more than 8 gig then it should be 0.75 of mrmory size
    if this is the method then for my ram size i need to set 48 Gb
    is this is right size , i am wondering this size seems like very huge size
    pls advise what is the right size for 64 gb RAM
    RDS

    The documentation states:
    http://download.oracle.com/docs/cd/B19306_01/install.102/b15667/pre_install.htm#i1011296The system must meet the following minimum hardware requirements:
    swap space ... More than 8192 MB -> 0.75 times the size of RAM>
    So, probably it will work with less memory but if you want a supported configuration, then assign the required space, hard disks are so cheap.

  • Swap space for multiple instaces on the same box

    OS: Oracle Enterprise Linux 5 Update 2 (64-bit)
    DB: 10.2.0.4
    I'm fairly new to Linux and have a general question about configuring swap space on a Linux box running 10g. From the 10g: Managing Oracle on Linux for DBAs class, Oracle gives the following recommendations about swap size:
    RAM (Swap)
    <= 2Gb (150% of the RAM size)
    Between 2Gb - 8Gb (Equal to the RAM size)
    8Gb+ (75% of the RAM size)
    It's not clear to me from reading the book if this recommendation is good for all Oracle processes running on the machine, or if it's a per instance value? The box has 16Gb of RAM but there are going to be three instances running on it and I need to verify that 12Gb of swap will support all three without issue or if I'll need to configure 12Gb swap per instance.
    Appreciate any input.

    As noted earlier in this thread, swap space is an operating system property, and has nothing to do with software you want to run on top of it, like an oracle database.
    The function of swap space is to be able cope with memory allocations beyond the amount of physical memory. In most occasions you do not want to use swap space, because it has a severe performance impact (memory blocks have to be exchanged from the swap device to physical memory).
    (please mind that on some unixes (AIX and HPUX if I am not mistaking), swap is pre-allocated for processes which means the swap size is not only depended of operating system and memory size, but also the number of processes. Linux does not do that, it starts to allocate swap pages under memory pressure. There are certain issues with some memory settings in linux (linux kernel memory management is quite automatic) that can get your system to page. (memory overcommitting is one thing))
    In my experience, the amount of memory which is used is depended on the amount of memory on the machine in most cases. Whilst this sound simple, think of it: with 2GB used, probably most DBA's would allocate approximately 1.5GB to the databases on that machine, if your machine got 16GB you probably want approximately 14GB to be used by the databases.
    This means (for me) that I use swapspace with the same size as the amount of memory. That few extra GB's allocated to swap won't cost you or your company an arm and a leg, so have that for not running out of memory.

  • Checking Swap space from OS level in HPUX

    Hi All,
    We have some issues with swap in our SAP production system when I checked the ST06 Tcode
    Swap
    Configured swap     Kb    20,971,520     Maximum swap-space  Kb    54,389,460
    Free in swap-space  Kb     8,945,160     Actual swap-space   Kb    54,389,460
    And when I checked from the OS level ,it gave me the following result

    Does it mean that total swap space is (1048576 + 19922944)KB which is 20GB?
    If yes ,then how to increase the swap space in UNIX based systems?
    SWAP SPACE = 3*RAM? If yes ,do we need to put swap size =60 GB?
    In ST06
    what is the difference between CONFIGURED SWAP-SPACE and ACTUAL SWAP-SPACE?

    Hi,
    Thanks for ur reply but when I checked it from OS level why it is showing only 20GB ?
    What's the diff between configured and actual swap space ?
    I checked SAP Notes :146289 and 153641
    They clearly says that swap space should be atleast 20 GB plus 10 GB for additional Instance for the server.
    In our landscape we have CI and 4 dialog instance connected to it
    that means our swap space should be 20 + 10*4=60 GB
    We are having HPUX server and ST06 Swap values are
    Swap
    Configured swap     Kb    20,971,520   Maximum swap-space  Kb    54,389,460
    Free in swap-space  Kb     8,697,960   Actual swap-space   Kb    54,389,460
    Do we need to increase the SWAP Space to increase the system performance?
    What is difference between configured swap and actual swap space ?
    SAP Note 1112627 clearly says that SWAP SPACE = 2* RAM for HPUX servers.
    What do you guys say about this?

  • Swap space becomes critically low in the system

    Hi,
    We are facing a situation where the swap space space  is critically low in the system, there is just 10 % available swap space in the system
    And we can't see the swap space being released to the OS .
    This is one of the  Application servers we have for R3 system.
    SAP environment:
    SAP Netweaver 7.01
    LINUX RHEL
    Oracle 11g
    $free -m //outut
    As you can see we have 64G physical memory allocated to this application server whereas the configured swap space is around 20G.
    This Linux box houses two application server one for R3 and the other for CRM.
    Would appreciate if you can tell me what should be done to release the swap space as above shows that 18 gig of 20 is being used right now.
    Regards,
    Rakesh

    Thanks Gaurav..
    what you have said makes sense we will check that parameter which determines to what extent swap space should be used between 0 to 100 %.
    However, I have found that there are many swaps in the SAP buffer (ST02) that we will be tuning soon in both of the application servers that I had mentioned above,
    I have checked the ST06 and couldn't found any page in/out activity.
    see below the screen shots of  ST02 and ST06 for both application servers.

  • Installation problem (swap space)

    hello there ,
    I have such problem when i am trying to install (oracle 10g release2-forms developer)
    that when the installer begins to check the requirements to install the product it give passed for all the requirements except one failed, it's (swap space) ,the installer give me the following message : swap space 744 required 1533 << Fail.
    my question is what is swap space? and how can i fix it? can it be cuased by avirus?
    and when i am trying to install (release1 oracle 10g form developer) it passed the requirements but after 80% of intallation of the first CD it abort's the installation and give me the message: abnormal event has accourd please support the following files to oracle c:\Program Files\oracle\inventory\out
    c:\Program Files\oracle\inventory\log
    c:\Program Files\oracle\inventory\install
    what is my computer problem? please heeeeeeeeeeeeelp .
    thank's for all.

    It has to do with the virtual memory settings, those can be verified at the system advanced properties. Make sure you have declared enough space, at least the minimum required by the Oracle Universal Installer.
    On the other hand, you were prompted for a file where the install log is recorded, please verify the contents of this file, further issues may have to be solved.

    Currently we have a issue of swap space getting used up nearly 100%. The system was out of memory and can't run any applicationThat is unusual and should not be happening when you have what seems to be an excess of memory available. This could mean some kind of bug (memory leakage for example), or it could mean plain old fashion abuse of memory. Like PL/SQL code that attempts to bulk fetch a few million rows from the database with a single go.
    On checking Metalink note, it said its an unhandled Oracle exception; have to increase the swap space.Wrong IMO (unless you were not following the recommended swap size factor). If you have have a giant swap area..moving the wall a few meters away (by increasing swap) will only enable you to run faster into it - I doubt that this is the intent of that Metalink note.
    On increasing the swap space, and restarting the instance, the system was normal.
    Now why does oracle use up all the swap space and what can be the workaround to avoid this in future?Oracle only use what is needed to perform the client requests that it receives. If the client request a mountain of data to be moved/processed, Oracle will try to oblige. If that mountain topples and crushes server resources, it is not Oracle that is to blame for trying to do exactly what was requested from it.

  • JVM crashes with Out of SWAP space

    Hello every body,
    We have a problem in a production environnement. The JVM crashes every time with the log file below.
    The application which is running don't occupate all memory and we don't understand why an outofmemory exception is raised.
    It's not probably due to an allocation inside the application because the exception should be an outofmemory exception : Java Heap space.
    Please, somebody can help me to understant what append or to give me some advices?

  • Available swap space problem in solaris 10

    Dear All,
    Currently I am facing a most interesting problem regarding swap space.
    We have assigned mirrored slice swap space with 20G size. But when we are asking for swap space it is only showing around 2GB.
    1. Please have the swap area:
    root@palash # swap -l
    swapfile dev swaplo blocks free
    /dev/md/dsk/d1 85,1 16 41945456 35002784
    root@palash # swap -s
    total: 53562072k bytes allocated + 5689008k reserved = 59251080k used, 615704k available
    2. Please have the metastat output:
    root@palash # metastat d1
    d1: Mirror
    Submirror 0: d11
    State: Okay
    Submirror 1: d21
    State: Okay

    Stripe 0:
    Device Start Block Dbase State Reloc Hot Spare
    c0t1d0s1 0 No Okay Yes
    3. Here is /etc/vfstab entry for swap:
    /dev/md/dsk/d1 - - swap - no -
    4. But when we checked swap space using df command:
    root@palash # df -h

    Hello,
    Thanks for your reply.
    But I am not clear about your findings as we have around 64GB physical RAM in my machine.
    My question is that if we mount 20GB swap partition, then how we can see this is around less than 2 GB in df -h command.
    And even in swap -s command, this is showing same problem.
    What might be reason behind this????
    //PalashWell no-one else has anwered ... so its back to me.....
    Hmmm ... i would use the word observations rather than findings .... I am not on an old root explotation expedition all over our server .. merely observing on the morsels you show me ....
    Please be aware I may not be totally technically correct or be using right terminology on what follows so I welcome corrections ....
    Your machine has 64GB Memory, and a 20 GB swap file, therefore has the ability up to support 84GB total (Virtual) Memory ofr it's processes/buffers.
    The reason little swap is free (let us say 2GB ... thoug it may be 600m) is theat processes/buffers have a virutal memory requirement of 84GB-2GB = 82Gb.
    ... So rather than wondering about how come 2GB is left, start thinking about ow 82GB is being used.
    ...... Particularly with databases oracle RDBMS; mysql etc a big influencing factor can be how much memory is allocated its memory structures.
    .......... And a DBA may set these extremely high (memory_max / innodb-buffer-pool-size etc etc).
    ps -ef will show the (virtual) 'size' for individual processes
    prstat -a may help show what is going on (but may double account some things):
    ipcs -a would show the allocation for the oracle RDBMS memory_area,
    echo ::memstat | mdb -k ### may help ... but i have seen accounts of it taking ages to run.
    I'd also check kstat zfs ... but your not using zfs so no need to bother.
    .... You may need to show some evidence of how your applications are consuming virutal memory for someone to help you futher ... but if you do htis who may answer your own quesiton.

    Our database Instance Using Swap Space even When There is Plenty of Free RAM.
    We have 80GB of physical RAM, 32GB is set to oracle SGA_MAX_SIZE
    memory parameters:
    memory_max_target big integer 32G
    memory_target big integer 32G
    sga_max_size big integer 32G
    sga_target big integer 32G
    but still oracle is taking memory from swap even though we have enough physical memory.
    please find the top output

    I refered the metalink document id: [ID 761960.1]
    Database Instance Using Swap Space When There is Plenty of Free RAM metalink note [ID 761960.1]
    and tried the disabling the sga_max_size and memory_max_target and memory target with all different combination but no use.
    We have one more box where same setup was configured in solaris platform but there the above memory parameters are not disabled but it is not using swap space it takes memry only from physical RAM
    Can any one throw some lights on this issue. It wopuld be great if I come to know where the exact problem
    Thanks in advance

    Hi,
    I didn't say I am not using 11gr2 memory parameters I am using all the automatic memory parameters but the thinks is as per the metalink note I tried by disabling the automatic memory parameters. but that didn't help me in preventing unnecessary swap usage. So I reverted. now it is using automatic memory parameters.
    so What is the solution for this?
    With Regards,
    Boo
