Looking to see if this NFS issue is universal with everyone else

First I followed these directions exactly (and our filer is a Netapp):
http://www.oracle-base.com/articles/11g/OracleDB11gR1RACInstallationOnRHEL5UsingVMwareESXAndNFS.php
So the database has been created as per the end of these instructions. Nothing customized. No data populated or anything of any substance has been done yet.
But if I now follow the instructions in this link (you do need a Netapp NOW login, but basically on the filer you do a nfstat -z to clear the stats, then nfsstat -l to see the top talkers, and then nfsstat -h <IP> to see the kind of traffic per host):
https://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb36582
My top two servers by a long shot are the brand new RAC Nodes. Even more than the VMware NFS IP's used to carry all the guest vm traffic. After 10 minutes the top host had 450,000 NFSOPS. The third highest was less than 50,000.
The bottom of that netapp link states "If it looks like it is the culprit that is generating too many getattr, access, or other requests at a rate of 50% or higher at the expense of reads and writes, you should work with your UNIX vendor or support team to analyze that data and determine what processes on the host are running against the filer to cause so many unoptimized requests."
My values for "getattr" and "access" are 62% and 35% of the total traffic. My reads and writes are 2% and 1% respectively. According to Netapp this is a problem and hugely unoptimized. What the heck is Oracle or CRS doing? Anybody with a similar setup see the same thing? Is this a cause for concern? Should we bring it up with Technical Support or is this expected behavior for Oracle/RAC? Let me know what you all are seeing.
Thanks!

Hi,
I have same issue on one of my two RAC nodes.
We have NetApp 3020c and using a physical Dell PE 1435 server with RHEL 5.3 and Oracle 10.2.0.3 RAC.
Did you found a solution for problem?
Best Regards

  • Canon Issues. As with everyone else.

    I've had great success with Canon and iMovie on my macbook. Now It's time to use the GL2 with FCE on my G5. It worked the first couple of times, then it quit recognizing it... but I was still able to use capture now. However, today is a new day.
    When connecting the GL2 via FW400 I see it in the system profiler as an "Unknown Device." If I daisy chain it through my Lacie 2BigTriple (FW800) I get nothing...
    The GL2 has also been known to freeze FCE and then "disconnect" my lacie. It then takes forever to restart... unless I unplug or turn off the camera.
    Basically, Why won't Canon cameras connect? This is crazy and I have myself because I have an HV20 being shipped to me tomorrow at 10:30 am. Was this a mistake? (as in should I have bought a Sony...) Will I ever be able to connect this camera to my ol' computer?

    The problem is the Firewire implementation on the Canon camera. Disconnect your Lacie drive (and any other Firewire devices connected to your G5). Make sure your GL2 is the only device connected to the G5's Firewire ports. Capture to your internal drive.
    You might consider getting a separate FireWire card for your G5 in order to have a second Firewire bus. Then you could connect your Canon cam to the card and your Lacie drive to the G5's onboard Firewire ports. Since they will be on separate Firewire busses there will be no conflict.
    OWC can recommend a card that should work.

  • Burning CD issues *it seems like everyone else too* Error Number 4280

    Has anyone figured out what to do with this burning CD's issue that it seems like everyone is having? Now I'm gettng "Error 4280" and I've NEVER had any problems before! It all of a sudden just started, and I JUST want to burn a couple of CD's! I'm not sure what version of iTunes I'm on, but I think the newest one, and now I'm having nothing but trouble. I'm worried about losing my library too and don't know about un-installing and re-installing either. Are they working on this? Does anyone know? I don't know if I even want to purchase any new music at this point ...
    Thanks for any advice!

    Nope, didn't work, it was already on "Audio CD", even tried buying some new CD's specifically made for music. iTunes knows that have a huge problem with this and they don't care. How dare they just ignore the fact that they screwed up with the new upgrade and not respond at all to this situation. There is honestly nothing else I can think of to do to be able to burn CD's *not to mention that I waste a CD everytime I try, because someone said not to use cd-rw*. I ran all the diagnostics and it said everything as fine. IT'S ITUNES ITSELF.
    Thanks for trying to help, I appreciate any suggestions.
    Once again, if anyone can think of anything at all that might be causing this problem, please let me know ...

  • Looking to see if this VBA subroutine can be made more efficient

    To All,
      I have put together a SUB that depending on a constant averages those numbers together then starts the process of exponential smoothing of the number until the last row of data.  As it does so, it checks to see if it is at the last row and then
    copies the last number to row 2 of the same column.
      It works fine, but seems a little slow for just 11 columns and 200 rows.  Any thoughts on how to increase the efficiency of the routine?
    Thanks

    Hi Harry,
    >> It works fine, but seems a little slow for just 11 columns and 200 rows.
    I don’t quite understand the goal you were trying to achieve through the code. Based my understanding, accessing 2000+ cells and changing the formula cell by cell may make the macro running slow.
    Since I’m not very familiar with your business requirement, I’m not sure whether it is possible to put the logic on the formula instead of changing the formula dynamically through VBA.
    Hope it will help.

  • Why cant I see "On this Iphone" tab in Itunes with 5s?

    I have just purchased a new iphone 5s and backed it up with a previous iphones data, but when i go to manually manage my music in itunes i cannot see the "On This Iphone" tab which would show me the music list on the iphone. I have plugged in a brand new ipod mini and the tab appears, so it is not my itunes version. Any ideas?

    You mean Restored.
    Did you then sync the iPhone?
    Restoring form a previous backup does not put apps, music/photos etc. onto the new device.

  • Design Issue by Universe with lot of dimensions ..

    Hello,
    I have 5 to 6 Fact tables with a big amount of diemnsions (about 50). These Dimensions should be used for categorizing and filtering data in different Reports. Looking for a design solution for my Universe i thougth about 2 Scenarios:
    1. Dimension Tables
    for every Diemnsion i have to create appropriate table and join it with fact Table (All 50). Drawback: Performance will suffer with 50 Joins to the Fact Table.
    2. Without Dimension Tables
    Only provide the Dimensions directly from tha fact table. Drawback: less flexibility being dependent from the Input in the foreign key of fact table second drawback we have to create same dimensions for every fact table (5 fact x 50 Dimensions)
    Any proposition for an adequate solution ..??
    Thanx

    You need to consider your data warehouse design if you are suggesting that you should take dimension objects from the fact tables.
    This sounds like it should be a standard multi-star universe.
    Step 1:
    Insert your tables
    Step 2:
    Create your joins, making sure that you set the one-to-many cardinalities in the right direction
    Step 3:
    Click on detect contexts; there should be one context suggested for each fact table. Accept them all.
    Step 4:
    Build your classes and objects to add value, not to simply replicate your data structure.
    We can get on to best practice for universe design at a later date.
    One BIG caveat when inserting dimension tables. Do they mean the same thing to each fact table? If they do, then they are conformed dimensions. If they are dimension tables that have different uses for different fact tables then they should be aliased (e.g usage of date table as order date vs. employee start date)

  • Performance issue using Universe with SNC connection

    I had a dynamic dashboard using Live office > Webi report > Universe > Bex query which was working fine but we recently implemented SNC between Business Objects and SAP BW due to which the universe connection has been changed to use sign on connection. After changing the connection in the universe I am see a performance degradation refreshing the connections in xelsius dashboard. Earlier the connection refresh time was 6 sec now the refresh time is around 30 secs, Intersting thing is I have tryed refreshing the webi report the refresh time of the webi report did not change which is still less than 6 secs and I have also tryed refeshing the Live Office component directly in the design/spreedsheet mode of the xcelsius even here the refresh time remain same less than 6 secs.
    The connection refresh time is bad only when I am in preview mode or if I deploy the swf to the business object server.
    Xcelsius Version: 2008 (5.3)

  • Sync To CRM Time - Does This Cause Issues For Anyone Else?

    I have been a long-time Eloqua user. Primarily, the companies that I have worked are B-to-B and serve small businesses.  In the small business lead generation world, when you wait to respond to leads - you lose. The first one in usually gets the deal.  We have all of our lead generation activities running through Eloqua, including our PPL campaigns where multiple competitors are also responding to RFQ's and also our inbound sales call center uses it (via form) to submit leads in order to take advantage of the de-duplication and validation power in Eloqua.  The latter causes my sales team to wait 15 minutes while they are they are waiting for the lead to get created and transferred to them in CRM. 
    Here is my issue.  At best, it takes Eloqua 15 minutes to sync the leads to SFDC.  These programs are "straight to queue" integrations too.  I am running integration events straight from the form processing steps, so there are no program builder delays here.  The guys in Support have been really great, and have been working with me to see what can be done to decrease the lag time, but 15 minutes seems to be the acceptable rate. So, I am starting to think of ways to take them directly to SFDC and just live with the issues of duplicates and no validation.
    I can't be the only one that this causes issues for.  Does anyone else have this issue?

    Hi John,
    I too have had these issues.  The main problem is not program builder.  The integration queue/engine is prone to backlogs.  Rumor has it that the integration engine is shared by the campaign engine and a bunch of other services in the platform.  Either way, the integration queue will always have a lag.
    My solution was:
    1.  Push data from ELQ form to a SFDC Web-toLead Form IF ELQ contact has blank LeadID and ContactID (does not exist in SFDC) -- this creates leads instantly in SFDC.
    2.  Run an apex trigger from SFDC to do a blind form submit to Eloqua with the email address and SFDC Lead ID for the leads created from step1 -- this will ensure that creating duplicate leads in SFDC is minimized.
    3.  Send notifications from ELQ form to Sales Reps if ELQ contact already exists in SFDC as Lead or Contact. -- even without the updates on the lead or contact records in sfdc, this gives the reps an immediate heads up. 
    4.  Send the rest of the information that I couldn't fit into the post-data-to-server step for the new lead.
    Of course I also baked into the form processing steps a bunch of conditions to mitigate spam.

    My iPad is acting funny after 6.1.3 update the only way I see fixing this issue to downgrade but I can't find anything on downgrading

    Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)

  • Is this an issue with Windows 8.1 Enterprise Main theme or with my Laptop Screen??!!

    Hello,
    I currently found a strange issue happening with my display and it only occurs when I am setting my desktop background as the Main Windows theme or any picture I set as a theme.
    When I click inside any open folder as shown in this recorded video and when I click on Desktop, doing this back and forth and I notice quick flickering inside the open windows.
    You will see this at second 0:26 in the video.
    https://www.youtube.com/watch?v=3-8z8Ef2DcY&feature=youtu.be
    It is also obvious in this video, I am doing this with the Intel Graphics Control Panel window.
    The issue occurs at the time 0:10 and 0:25
    https://www.youtube.com/watch?v=ntqNC1gUtHU&feature=youtu.be
    Note: This only occurs when I switch between themes for the first time.

    Well, here are my latest results.
    Now, I am 100% and I can guarantee you that there is a still issue within Windows 8.1 theme.
    I installed Windows 8 again, now see how the Device Manager looks like, see the Display Adapter driver.
    It's Intel(R) HD Graphics 4000 (Microsoft Corporation - WDDM 1.2)
    And now before I install any drivers or programs when I switch between themes and then switch back to that Main blue theme, no single flickers happens, so that means Windows 8 has no problems?
    Looks like when you released Windows 8, you included graphics drivers for each system to install automatically after Windows install. Now the Windows Main Theme is a blue flower.
    I installed Windows 8.1 again, now see how the Device Manager looks like, see the Display Adapter driver.
    It's Microsoft Basic Display Adapter.
    And now before I install any drivers or programs when I switch between themes and then switch back to that Orange color theme, I get screen quick black flickering, so that means Windows 8.1 may have got issue when switching back to the Main theme.
    I have also read this in this link
    http://msdn.microsoft.com/en-us/library/windows/apps/dn344644.aspx
    Windows 8.1 x86 and x64 graphics driver availability status
    Windows 8.1 graphics driver deployment changes (x86/x64)
    Windows 8.1 doesn't include in-box, third-party GPU drivers. Instead, drivers are provided via Dynamic Update during the operating-system (OS) installation or upgrade process, or via Windows Update after the initial boot of the OS. Customers installing
    Windows from a USB flash drive or ISO image while not connected to the Internet get the Microsoft Basic Display Adapter driver with limited functionality. Customers are encouraged to install Windows Hardware Quality Labs (WHQL)-certified third-party drivers
    from Windows Update, OEM, or independent hardware vendor (IHV) websites when available.
    Now, I thought of an idea. I thought that if replaced that Microsoft Basic Display Adapter which is in Windows 8.1 with that in Windows 8 (Intel HD Graphics 4000 Microsoft Corporation WDDM 1.2) The issue might be fixed.
    So I reverted back to Windows 8 and used DriverMax to make a backup of the graphics driver.
    Now, I reverted back to Windows 8.1 and used that DriverMax software to restore that graphics driver which was pre-installed in Windows 8 but still the issue isn't fixed. :(
    I am sure the issue that causes this black flicker on screen when switching back to the Main theme and then closing down the
    Personalization window isn't related to the graphics hardware or the driver.
    I am pretty sure Windows is causing this.
    I think you should get a fix to this please, work on a fix for this flicker that happen when switching themes I am pretty sure the other issue that causes flicker on my open window when clicking inside it and outside it will fade away.

  • I am looking to see if anyone has found out how to do a sum or percentage totalling other columns or rows in Numbers?

    I am looking to see if anyone has figured out, from their iPad in Numbers how to calculate percentages or sums totalling other columns or rows?

    The issue is I bought the G4 from my buddy a few months ago... the machine has been abused to say the least, both inside and out. It is almost falling apart and has a BUNCH of programs loaded on it. I have always used a PC and am still familiarizing myself with Macs, I need to clean out the machine and dump all the excess applications and files that are causing problems.
    I think this is why I am having some trouble. Sometimes it works just fine, but I am only working with a few simultaneous tracks at a time. I am using the virtual instruments at this time but will be running guitars and bass through an external sound card soon. Similar to what you are doing it sounds like.
    Anyway, wanted to give you some more insight. Last night it seemed to work alright, I am not going to rush into buying anything until I absolutely have to but want to get some direction as far as what I should be looking at.
    Any further input is appreciated, thanks.
