Help requested on FireWire (SBP2) on CentOS 4.5 for Oracle RAC installation

I am running 64-bit CentOS 4.5 (2.6.9-55.EL kernel) on AMD64. I can load the FireWire modules (SBP2, OHCI1394 & IEEE1394) and see the partitions created of the FireWire drive using fdisk -l. The /proc/scsi/scsi correctly shows the drive.
If I create an EXT2 or EXT3 on a partition, it's great. I can read/write on that without any problem. But when I try to perfom the following:
dd if=/dev/zero of=/dev/raw/raw1 bs=8196 count=12000 or any dd on any partition on that drive, I am getting:
ieee1394: sbp2: aborting sbp2 command
scsi4: destination target 0, lun 0
command: Read (10) and then bunches of numbers
ieee1394: sbp2: hpsb_node_write_failed
ieee1394: sbp2: Bus reset in progress -- rejecting command
But the dd finishes and I can see the partitions using fdisk -l
I have the following in the /etc/modprobe.conf file (also tried without serialize_io):
options sbp2 serialize_io=1 exclusive_login=0
Eventually, this problem is stopping me from implementing CRS & Oracle RAC.
Can somebody please tell me what's going on & how I can avoid these errors?
Thanks for your help.

Hi,
Did you compile the source code which downloaded from Oracle official website:http://oss.oracle.com/projects/firewire/files/source/oracle-firewire-modules-1286.tar.gz ?
Please check the following modules whether it have been loaded on the box.
1,ieee1394.ko
2,ohci1394.ko
3,raw1394.ko
Use "dmesg" to check if the disk connected to the firewire interface has been detected.
Regards
Terry

  • Need help converting Excel IF statement into CASE WHEN statement for Oracle

    Hi,
    Hope someone can help I have tried various ways of getting this to work, to no avail!
    Bascially I have some figures that are minus figures, and I need to add them together to get a movement figure, but I need to treat the minus figures as minus, if that makes sense, rather than the usual... a minus and a minus makes a plus.
    For example:- Budget Figure = -1% and Actual Figure = -68% so the movement needs to be -69%.
    The IF statement I have been using in Excel is the following:-
    =IF(FO110<0,(FP110-(IF(FO110=0,1,FO110)*-1)),FP110-IF(FO110=0,1,FO110))
    Which when using the figures as above = -69%
    Cell FO = The Budget Figure
    Cell FP = The Actual Figure
    However, when I created the CASE statement in Oracle, the figure in the query comes back as -0.67, which is oviously not what I want to happen when both actual and budget are minus figures; however when they are a minus and a plus, it works perfectly fine.
    Any help on this would be most appreciated!
    Kind regards,
    Annmarie

    Happy I did'n mess something up :)
    Nevertheless, don't show it too much around because
    case when budget < 0
         then actual - case when budget = 0  /* will never happen */
                            then 1           /* will never happen */
                            else budget
                       end * (-1)            /* -budget * (-1) remains only */
         else actual - case when budget = 0
                            then 1
                            else budget
                       end
    endso at least try the following (if case is more readable as decode for you). Let's hope it works as I don't have a Database at hand
    case when budget < 0
         then actual + budget
         else actual - case when budget = 0
                            then 1
                            else budget
                       end
    end Regards

  • Help Required for Oracle 9i Installation on Fedora Core 3

    I am new to Linux on Oracle and wanted to set up oracle on Fedora Core 3.
    I have downloaded Oracle9i Database Release 2 Enterprise/Standard Edition
    for Intel Linux from http://www.oracle.com/technology/software/products/oracle9i/htdocs/linuxsoft.html
    I have downloaded it on Windows XP Can any one please suggest me what should be the next steps to install it on Fedora Core 3?
    Thanks in advance

    So copy downloaded installation from Windows to Linux machine using SCP.
    You can download GUI SCP client here: http://winscp.net/eng/index.php
    If you preffer command line tool then you can use PSCP tool: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
    Then use some installation steps for Fedora for example you can use mine (follow exactly all steps):
    http://ivan.kartik.sk/oracle/install_ora9_fedora.html
    Just little advice don't use root to login to Linux computer, use oracle instead (once it is created).

  • Urgent help oracle rac

    Hi experts ,
    I have 2xv890 with 1x3510 oracle rac cluster , i have did the installation of the cluster successfully , and CRS installed also successfully , but when start installation of database run root.sh , in the stage of VIP configuration i select the interface of VIP then start to install , i got when trying to install GSD stop at 15% and dialag empty error msg coming up .
    I dout the problem in VIP configuration , any one can tell me how to configure that ,
    another question is it required to have same interface names for both servers like, if ce1 in one server ,so another server also ce1 for public.
    is required for private interface ??
    please help .

    I'm not clear on what the VIP part plays in the Oracle RAC installation, especially in root.sh.
    When you install CRS, the last part of root.sh on the final joining node is to create all the clusterware resources, VIP, GSD and ONS. Are you certain that this bit has completed successfully? What was the crs_stat output like? There is a bug in 10.2.0.1 where it won't install properly if you are using an RFC 1918 public network address.
    You will need to use the same interface name for the public networks. That is a requirement in the Oracle documentation IIRC.

  • My hard drive is slower than ever - Late 2009 iMac - help requested

    I was testing my hard disk via BlackMagic Disk Speed Test across the network (for copying files from my MacBook Pro to my Late 2009 iMac, and I was shocked at the write speeds.
    Because of this, I went to the machine and ran local tests, both BlackMagic and xbench. Suddenly I was horrified when I saw the performance for write operations well below the speeds I'd observed in the past. Luckily, I had saved xbench files so I had the ability to compare old disk tests. In the summer of 2013 running 10.7.3, this same hard drive had an uncached write speed of 116 MB/s [4K blocks] and 94 MB/s [256K block]. Now, the drive running under 10.9.5 is performing very inconsistently, with top speeds around 80 MB/s and averages more like 50 MB/s.
    I cannot think of any significant changes to tools or background applications installed since that time, so I ran EtreCheck -- the results of which I'm pasting below.
    Any guidance as to what I should test would be greatly appreciated. Thanks for reading! --
    Chris
    Problem description:
    Hard disk slowed to less than half the speed from Mac OS X 10.7.3, as I am now on 10.9.5 and the speed appears to be roughly 40M/s uncached write down from 119M/s previously. I am using the same drive, memory and most of the same applications.
    The only large difference is the OS.

    Hi Eric -
    I did a horrible job of explaining *when* the slow performance became noticeable. These changes did not happen when I installed Mavericks, I just don't have benchmarks *saved* to give the support community exact numbers after Mavericks was installed. The performance at that time was roughly the same, although you might recall that the old app xbench no longer worked to give a comparison because one or more of the sections of testing wouldn't work (memory, if I recall correctly, although I will run it when I am back at that machine and post here).
    In any case, the only significant change since the slow down is the OS, but the decline in performance was noticed in the fall. It wasn't until I tried this network copying task the other day that I decided to run BlackMagic's test. This is when I realized I should go check the performance on the local machine. Having already run through many of the generic recommendations, I thought perhaps someone here who has a much deeper understanding of the storage abstraction layer would have guidance on specific preference files that might be corrupted since I can't find any tool to check them. I've noticed that many of the people seeking guidance are not very technical and the advice is similarly geared. I'm sure I could spend a little time this week finding comparable tools in Mac OS X to those I'd have used in the past on Windows (Sysinternals) to do real time debugging and process analysis.
    So far I have found that there were a few processes running high, like the dashboard client, so I moved (deleted) the preference file and rebooted. This resulted in the gain to that 60 MB/sec write performance (up from the low of 40 MB/sec), but there must be other areas yet unexplored.
    At this point I'm considering a fresh install, but I'd been told in previous exchanges when I first started developing on Macs (2008) that fresh installs were rarely the best solution on Macs.
    Can you give me guidance on that? You probably know that in the Windows world it is often (depending on how you define often) necessary to format and reinstall the OS. As a long time systems architect developing everything from device drivers to enterprise solutions, I see that as a result of the attempts to maintain legacy support for so long and the convoluted resulting APIs and failure to make real fixes for fear of causing problems with older hardware and software. Would you suggest erasing and reinstalling?
    @BobHarris - I know that's a problem and it's why I monitor the drive more than I do drives in other systems. My drive didn't qualify for replacement, but I think Apple doesn't always do a good job with the recalls. I was very fortunate that my old white MacBook qualified for quite a few replacement parts so it's a great browsing-the-web computer now, but at its age, it isn't capable of running most of the apps I need. I have considered selling the 27" iMac but when I last had it in for warranty repair, the DisplayPort was misaligned to the case, so I'm going to have to pay labor just to get it popped open to fix that (since the service center says they didn't cause the DP problem - although they must have!)... In any case, if I have to spend that money, I might as well use the drive doubler kit since I never use the optical drive in that box anyway. Mostly I love having it because of the gorgeous big screen. That being said, costs of repairs are silly when I can just buy another used MBP circa 2012 and get twice the processing power then use a CalDigit dock like the one I use with my existing MBP to use an inexpensive HD TV for the monitor.
    Thanks for the replies folks - the input is awesome!

  • AT selection-screen on ON HELP-REQUEST

    Hi
    What is normally done in the Selection Screen event :
    AT selection-screen on ON HELP-REQUEST.
    Normally pressing F1 helps gives Documentation present in Data Element assoicated with the field. Exactly in what cases would we be needing to use this event.

    Hi,
    That event is used for search.
    at selection-screen on value-request for p_file.
      call function 'F4_FILENAME'
           exporting
                field_name = 'p_file'
           importing
                file_name  = p_file.
    If you code in the same manner in the selection screen you will able to search and select a file from your work station, so that it will be uploaded in SAP.
    I hope this will help you, if not plzzz be back.
    CHEERS
    If your problem is solved award points and close the thread.

  • PROCESS ON HELP-REQUEST

    Hi
    wat is importance of POH. what If there is no PROCESS ON HELP-REQUEST ?
    Thanks and regards
    - Puneet Sharma.

    To display data element supplement documentation, you must code the following screen flow logic in the POH event:
    PROCESS ON HELP-REQUEST.
      FIELD <f> [MODULE <mod>] WITH <num>.
    After PROCESS ON HELP-REQUEST, you can only use FIELD statements. If there is no PROCESS ON HELP-REQUEST keyword in the flow logic of the screen, the data element documentation for the current field, or no help at all is displayed when the user chooses F1. Otherwise, the next FIELD statement containing the current field <f> is executed.
    If there is screen-specific data element supplement documentation for the field <f>, you can display it by specifying its number <num>. The number <num> can be a literal or a variable. The variable must be declared and filled in the corresponding ABAP program.
    You can fill the variables, for example, by calling the module <mod> before the help is displayed. However, the FIELD statement does not transport the contents of the screen field <f> to the ABAP program in the PROCESS ON HELP-REQUEST event.

  • Need help on buying FIREWIRE/USB-compatible for Logic Pro 9.0.2 on my SL

    Hi...Im in needs of help in my new OS Mac World.Had my Logic Pro 9(9.0.2) install in my Snow Leopard(10.6.3).Need help on buying FIREWIRE/USB-compatible for Logic Pro 9.0.2 on my Snow Leopard.Just a real basic audio interface that works with my Macbook pro Specification.You're help will be much more appreciated..
    Best Regards:RatzyMazzy

    In any case I would suggest to get an audio interface which is *Core Audio* compatible. This means that you just need to plug it in and it will work with OS X’s integrated driver. I once had an M-Audio interface which needed its own driver and it had latency problems because of them. I am currently using the EDIROL FA-66 with 10.6.3 on my MacBook Pro. It still works flawlessly and has worked without problems in the past with 10.4 and 10.5, too. Here is how it looks like: http://www.rolandus.com/products/productdetails.php?ProductId=731
    I have also heard good things about the FireWire interfaces from Presonus, like the FireBox.

  • Need Urgent Help With Alesis Firewire 8: 10.6.5 cannot recognize the mixer?

    I managed to install all the up to date drivers on the Alesis website (as instructed by the manual). THen restarted the computer and when i go to my SYSTEM PREFERENCES to change the AUDI/MIDI to the mixer, the mixer isn't even there as an option (although it is on and connected to my macbook via 6-6pin firewire cable!
    -I also went on *ABOUT THIS MAC > MORE INFO > FIREWIRE >* nothing here just "Maximum Speed: Up to 400 Mb/sec"
    - THen I went BACK TO SYSTEM PREFERENCES, under OTHER there is a MULTIMIX icon but when I click on it it says "+Preferences Error. You can’t open MultiMix Settings preferences because it doesn’t work on an Intel-based Mac.+"
    - What im wondering about is the fact that I am running *Snow Leopard OSX 10.6.5* and on the alesis website [http://www.alesis.com/multimix8firewire#] Under Docs & Downloads of the Multimix FireWire 8, the latest drivers available for download are:
    1)MultiMix FireWire - Macintosh Drivers [v3.5.3.8671]
    Adds support for Mac OS 10.6.3 Snow Leopard.
    Updated by Alesis 06/16/2010.
    2) MB zip
    MultiMix FireWire - Macintosh Drivers [v3.4.2.6300]
    Adds support for Mac OS 10.6 Snow Leopard.
    Updated by Alesis 09/14/2009.
    Like i said, I am running * Snow Leopard OS X 10.6.5* so which one should I download? I have tried both and none have worked. I am frustrated. Somebody help me please! Thanks in advance.

    Gave them a call today. Apparently, it has to do with the version software im running (10.6.5 SL) which is too high. Because their latest available driver for download is for 10.6.3, I have to obtain the retail instal disks from apple to reformat my mac back to 10.6.0.
    Other than the fact that I had to wait 40 mins on phone hold before getting an Alesis customer service to help me, what bothers me the most is the fact that they said having a macbook with 10.6.3 should be compatible with their Alesis device, yet they were UNSURE about whether anything running higher than 10.6.3 would work with their interface. I think its important to let customers know that, yet they fail to do so.
    Does anyone know how long it takes to receive retail snow leopard instal disks?
    and thanks for the help!

  • Help requested: mobile me to iCloud forced move?

    I just got an EM from Apple saying I have to move from MobileMe to iCloud. As I read it, iCloud REQUIRES Lion.
    I am running snow leopard because I still use the evil Intuit's Quicken 2007, which doesn't run on Lion. I've looked for better home finance software, but it's all garbage, so I hadn't made a move.
    In this switch, will I loose my Mobile Me Gallery and e-mail (the only two things I really use)? Do I have any hope to stay on SnowLeopard and move to iCloud? What are my options here (short of ditching Quicken or ditching my apple e-mail and gallery)?
    Thanks for any help, though I think the answer is "too bad for me."

    You will lose the Gallery whatever happens - iCloud has no equivalent facility and MobileMe will terminate at the end of June; so you need to look for a third-party alternative. This page may help:
    http://rfwilmut.net/migrate4
    It's possible to migrate to iCloud with Snow Leopard - go to http://me.com/move and when asked to confirm that your Mac has Lion, lie and say 'yes'. You can set Mail up manually to access iCloud email - details here:
    Entering iCloud email settings manually in Snow Leopard or Leopard
    There is an unsupported hack which can make Calendar syncing work, but the other facilities won't work: from what you say this won't bother you.
    You should migrate at some point before June and set the email up: doing this will not make any difference to your Gallery but as I say you will have to deal with this as a separate issue.

Maybe you are looking for
