EM Alert - Disk Utilization for 1 E: is 96.24%

I'm running Oracle on Windows Server 2003.
I've gotten about 6 alerts from the enterprise manager database console which say:
Metric=Disk Utilization (%)
Disk Device=1 E:
Timestamp=Dec 23, 2007 10:43:09 AM CST
Message=Disk Utilization for 1 E: is 96.24%
Rule Name=Host Availability and Critical States
Rule Owner=SYSMAN
Is this referring to IO on the disk or free space (which would be way wrong as its 63% free). If it is IO, is there something I should be doing to minimise it?

This is a HOST metric.(Type = Host)
To find your answer, you would go to the Enterprise Manager documentation at http://download-east.oracle.com/docs/cd/B16240_01/doc/nav/portal_booklist.htm to find the "Enterprise Manager Framework, Host, and Third-Party Metric Reference Manual" in the lower right column.
Once you have the document you would search for Disk Utilization to determine the rule being used.
In THIS case, however, you would also want to refer to Metalink, specifically note 303788.1 - where we find that
1) The metric is actually "Disk Device Busy (%)" in the above doc, (so searching for Disk Utilization' does not work) and
2) Per Microsoft KB article Q310067, there is an error in the number Oracle uses.

  • EM Alert: Critical: server - Disk Utilization for 1 D: is 99.8

    in the last day's i receive the following error message every 2 or 3 hours:
    Metrik=Disk Utilization (%)
    Disk Device=1 D:
    Zeitstempel=12.04.2010 12:29 Uhr CEST
    Nachricht=Disk Utilization for 1 D: is 99.81%
    Regelname=Host Availability and Critical States
    first i thought it's because the "db_recovery_file_dest_size" parameter was to small, because it was set to 10gb and the FRA was almost 10gb. then i raised the parameter (without restarting the database), but the same problem after a few hours.
    select * from v$recovery_file_dest;
    d:\FRA\     21474836480     10648922624     10073876992     458
    is it necessary to restart the database after reseting this parameter?
    thx for your help!

    There are many bugs on metalink on this.
    Better to raise a SR with OSS.

    Hi Vikash,
    This "Disk Utilization" metric actually points to hos busy is the disk device (in percentage) and not a percentage of disk capacity. As a matter of fact, in the 11.1. Database Control, it has been renamed to "Disk Device Busy(%)".
    Regarding of the meaning of a disk busy, it is the percentage of time the physical disk is active. And it may no be a problem, as you can see at http://sunsite.uakom.sk/sunworldonline/swol-08-1999/swol-08-perf.html : "Complex systems can be 100 percent busy, but still have a lot of spare capacity".
    On the other hand, to check how "full" a Disk is, the metric 'Filesystem Space Available (%)' can be used. This metric represents the percentage of free space available in the file system. Also, the Filesystem Size (MB) checks the total space (in megabytes) allocated in the file system.
    Hope this helps.

  • Can a disk utilization be more than 100% as shown from alert notification?

    I received an alert notification from the GRID. The percentage is 670.94%? What does this mean? Is it possible to go over 100%?

  • Enterprise manager alert on disk utilization

    i was wondering if you guys here know what the "3" means?
    Disk utilization for 3 F is 90%, crossed warning (80) or cristical (95) threshold.
    I understand that "F" means drive "F:" but what does 3 means?

    Well, there is more than services to run Oracle on Windows. To do administrative works using EM, the user must be configured in the group, "logon as batch job" . But neither home or home premium has the option to manage groups. Additionally, as Ed mentioned, oracle never supported any of its products over any "home" edition of the o/s so using it for Oracle would be surely causing issues which in general would be bizarre only.

  • Grid Control showing excessive amount of disk utilization.

    Hi Folks,
    I understand that Oracle doesn't support their products 100% on non Oracle VMs, but I thought I might take a stab at it.
    I decided to stick with a simple installation of Oracle Grid Control running on a Windows 2003 R2 32 bit os, here are the steps I took.
    1. Run Guest OS Windows 2003 R2 32 bit on a Windows 2008 x64 running Hyper-V (Yes I know why not EL5 running XEN, long story)
    2. Install Grid Control with Database and Agent versions
    3. Patch agent and oms to
    4. Some minor issues, but managed to get by those.
    - First off EM Website shows down, got to take a look at that, probably need to fix the beacon, not sure!
    - Grid shows that the host running em is over 100% disk utilization.
    - According to Metalink this is a known bug in Windows 2000 Performance Counters (not 2003?)
    - More specially Microsoft KB article Q310067.
    - Metalink Doc Id: 303788.1
    - Note, I'm running 2003 on a Hyper-V Guest, so anything can go wrong!
    The specific error is:
    Metric               Disk Device Busy (%)

    More info:
    - Guest is running on a Dual Quad Core Xeon System with 16 GB of RAM
    - Guest has dedicated 4096MB of ram
    - Guest has dedicated 2 CPUS
    - Guest is configured with a Virtual Disk (specifically partition c:\) to be on local Hyper-V disk array

    - Windows 2008 Hyper-V host utilization is literary at most 5% (current is 1%)
    - Windows 2008 Hyper-V disk utilization according to graphs is showing 100KB/s usage (less than 1%)
    Temporary solution is to turn off the metric, but not sure if that's such a good idea.
    - Note that 11g EM and 10g EM running on Hyper-V server had the same issue.
    - Note that 11g EM and 10g EM running without visualization had no issues.
    Any thoughts?

    Although bug info says it for HP-UX, I've also seen the same problem on Grid Control running on Solaris.
    You may want to apply Grid Control Patch Set Update (PSU) [ID 1139563.1] to fix it.

  • Disk Utilization Warning

    I am getting Disk Utilization warning;
    "Disk Utilization for 0 C: D: is 98.9 %"
    Please help in getting what is this and how to resolve it?

    Get some more disk and move some of your datafiles to the new disk.
    See if you have unnecessary archived redo log files. If so, get rid of those that are older than the oldest backup you keep.
    See if your audit files, trace files, or alert log are taking up too much space. If so, move them elsewhere or delete them.
    See if you are accumulating data load files that you can get rid of.
    See if you are accumulating user reports generated by your application system that you can get rid of.
    Basically, you have two choices.
    1. Add more disk and move 'stuff' to it
    2. Get rid of 'stuff' you no longer need

  • Disk Utilization false alarms from EM dbconsole

    I have a instance on Windows XP. EM frequently reports disk problems that don't exist. Example below. The disk is no where near 100% so I don't know where EM is getting this. Has anyone else had this problem? Is this a bug?
    Metric=Disk Utilization (%)
    Disk Device=1 E:
    Timestamp=Jan 27, 2008 2:31:18 AM CST
    Message=Disk Utilization for 1 E: is 99.97%
    Rule Name=Host Availability and Critical States
    Rule Owner=SYSMAN

    No, E: is an internal drive where the datafiles for the database actually reside.
    One twist however, is that my windows roving profile attenpts to map E to another location. On this machine this does not happen since there is a local E driver but I wonder if the EM agent is somehow confused by this. In the Windows explorer the E drive actually displays the mapped location name, but when you drill down you see the local drive.

  • How does GC calculate the Disk Utilization metric.

    I am getting the following error:

    This is a 410 GB disc with 266 GB used. The oracle datafile only use 7 GB on this disc; the rest is for Symantic backup!

    Check the Notification Rule setting of Disk Utilization (%) in Preferences -> Notification -> Rules. Select Host Availability and Critical States to View or Edit.
    There may be a situation where OEM may not understand the disk space while checking available space.

  • Root cause for 100 % disk utilization

    Hi All,
    Whenever in one of the dailog instance disk utilization is showing 100% sap system is getting very slow,what is the root cause for 100% utilization .At that moment of time when I checked the CPU usage it showed 98% CPU idle. server is on Windows NT and around 13GB of RAM is always free.
    We have only one drive in the apps server.Can this be the cause of 100% disk utilization?
    Waiting for ur frequent responses.

    I have answered similar questions :
    [Re: Disk Utilization 100%]
    as described above, one thing that cause 100% disk utilization is that writer processes (and read process too) is concentrated only on a single disk (equivalent to single volume group or single logical volume).
    we can imagine that a large number of user hitting the single disk (where datafiles exist) on the same time with a huge transaction load.
    if we can manage writable datafiles in several locations (equivalent to several volume groups or several logical volumes) where several datafiles exist, writer processes (and read process too) will be distributed to that several locations, so that each location (each disk, each VG or each LV) utilization may not reach 100%.
    so it is important to design writable datafiles in multiple location in different disks to prevent 100% disk utilization.
    one thing should be remember is to consult with hardware and storage vendor if there is any possibilities bottleneck or I/O issue on your hardware or storage.
    hope it help you.

  • Disk utilization 100% for very long time - ntoskrnl.exe

    I have HP ProBook 4530s running Windows 8.1 Pro x64. Until recently it worked without any problem but since last week disk utilization has been constantly 100% immediately after laptop has been turned on and I have logged on with my domain user account (this
    morning 100% disk utilization lasted for almost half an hour). In task manager ntoskrnl.exe is the one who is killing my hard disk. Is there any official Microsoft solution for this - I definitely want to avoid reinstalling Windows from scratch. I saw on net
    this was almost common bug in Windows 8.1 but without any solution working 100%.

    In order to diagnose your problem you will need to download and install the below
    Install the WPT (Windows Performance Toolkit) 
    Help with installation (if needed) is here
    When you have, open an elevated command prompt and type the following

  • Monitoring Disk utilizations,

    we have recently installed Scom 2012 in my organization and i have created manually to Disk monitoring.
    i set for 3 hour duration , every 3 hours it will keep on sending a mail .
    any other setting is there to stop this ,
    1)like once alert triggers till problem get resolve or disk utilization come to normal , dont want to creat same alerts.
    Regards, Velu M

    At first, Microsoft windows OS management pack has built-in disk utilization monitor which you can download from
    In SCOM, you can use either or monitor or rule to monitor the disk utilization. You can refer the following for the difference between monitor and rule.
    In you case, check whether you are using rule or monitor
    1) rule: rewrite the monitoring by using SCOM monitor
    2) monitor: make sure that the monitor does not automatic close

  • Windows 8.1 running extremely slow with high disk utilization

    My recently purchased Toshiba laptop with Windows 8.1 with 16 GB and I7 processor takes 3 minutes to start new programs. Running programs like Word, PowerPoint, Excel, PDF reader,etc stop in their track with every few minutes and show a circling
    cursor. Task Manager shows 100% Disk Utilization all the time.
    I ran McKAfee as well as Kaspersky to see if this was a virus/Trojan issue. Both came up with nothing.
    At this point the laptop (though spanking new) is completely USELESS and I have no hopes of using it !!!!!
    I noticed from many forums that I am not the only one facing this issue. The complaint count for this issue is growing in multitudes.
    Please help!

    Try these steps.
    Open task manager
    Click on processes tab. You can see all the apps and processes that are consuming memory.
    Click on top of column showing the memory. This will arrange them in ascending or descending order of how much memory is consumed.
    Find the ones which is consuming maximum memory
    Uninstall if you don’t need the program or app. Re-configure or re-install the software or app if it is an important one.

  • High disk utilization every 24 hours

    Hi all,
    While troubleshooting an user's complain about slow access to his mailbox on a Windows 2012/Exchange 2013 environment, I came across this interesting behavior:
    Disk utilization on the server will increase from 100KBps to 3000KBps (on average) and stay high for a good 10 hours or so. Then disk activity will go down for exactly 24 hours from the time it was up and increase again for another cycle.
    Basically, no matter how long it takes to go down, it will increase again 24 hours later. Looking at Perfmon and Resource Manager all I could see during both periods is that store.worker.exe is always on top, and READ has higher values. The issue does not
    appear to be related to business hours / backup window / client access to exchange, as it occurs at different times of the day and changes everyday.
    I believe it has something to do with an internal maintenance/reporting/monitoring feature of Exchange 2013, as it happens on 3 Exchange environments we manage, completely apart from each other.
    Microsoft Exchange Health Manager service has already been disabled as well as scheduled tasks under Microsoft/Windows/PLA and they all proved not to make a difference.
    Any ideas out there?

    Good Call. I just spent the last few hours going over 550,000 events. 
    I reviewed the application log for a 24 hour period and here is what I noticed:
    During the high disk queue period there are lots of entries for MsExchangeMailboxAssistants. For each of the 15 mailbox databases. 
    These only run during the High Disk Queues window.

    It appears the purge of orphaned mailboxes happens only at this time as well .
    These run throughout the day and not just 24 hours after the last restart/switchover.
    Calendar Sync

    So how do I get the first group of maintenance tasks to run throughout the day, or at different times, or at least not all at the same time for all 15 databases?
    Well, its all workload based, so I don't think you can readily adjust that.
    I'm more inclined to look at the specs of the mailbox servers. Are they up to the task and have they been vetted with the Mailbox Calculator?

  • Disk Layout for a RAC deployment on a shoe string

    Hi, not sure if this is better placed under RAC or Linux group.
    I am planning a demo RAC system using 2 linux servers and due to stingy managers, the smallest budget ever imagined !
    I will have the 2 servers networked but am looking at a cheapo disk setup ( excluding virtualisation and SAN/NAS ). I currently have
    Server A and Server B
    Each has an Internal disk of 250 Gb – I am going to place the linux OS on here, the 11gR2 Oracle Grid Infrastructure Home and the 11gR2 Enterprise Edition Oracle Home
    Q1. Since the local server is where the Oracle Instance runs – would I be correct in assuming this is where the SPFILE for the instance goes as well i.e. Server A and B will both hold an SPFILE in the 11gR2 ORACLE_HOME ?
    Q2. What else should be stored on the local server – all the usual logs etc ( eg the instance alert log etc ) ? Is it normal to put a copy of the database control file on each local server ?
    My plan was to carve up the 250 Gb disk into a root partition ( for Linux ) and a /u01 partition for the Oracle Grid Infrastructure Home and the Database Oracle Home
    I was then going to use the remainder of the 250 Gb Disk in Server A as the shared disk ( for RAC ) between the Servers.  I am going to attempt to NFS mount the remainder of the 250 Gb disk on Server A ( disgusted I have no budget for NAS ! ), so Server B will have access to it.
    What I was not sure about is –
    Q3. in regards to ASM Disk Groups, I wasn’t sure if ASM can discover disk space for use, once it has been mounted as a standard file system ( or in my case as an NFS mount ) ?
    Q4. How does ASM interact with standard file system mounts ( if at all ) ?
    Q5. If a physical disk has some standard filesystems mounted on it, can ASM use / discover any remaining part of a disk that has not been configured as a filesystem ?
    Q6. I am assuming the FRA is better placed on the Shared Disk ( so both nodes have access to it ) ?
    Any guidance would be appreciated,

    This won't be a RAC, Jim.
    What are you going to use as Interconnect? Do these machines have a 2nd physical NIC? You realise that crossover Ethernet cables are not supported. Is this Gigabit Ethernet? RAC Interconnect over a 10 or even 100 Mb/s  Ethernet, is significantly below par.
    Where are the OCR and Voting Disks going to reside?
    ASM is in my view, mandatory. It makes no sense not using ASM for RAC. ASM needs raw devices to use. It does not run on cooked file systems. NFS shares the latter.
    If NFS is used, over what IP layer is it going to run? The same as the Interconnect? Which would be  an irony as the the RAC db cache is now using the same transport layer as it does for physical I/O - both are over slow Ethernet vying for the same bandwidth.
    RAC is only as sound and as robust as the h/w it is build on. Stuff up with the hardware and you WILL have an inferior and unstable RAC. Accompanied with utter frustration as it will not work the way it should.
    IMO - the ONLY way one can build a 2 server RAC without a SAN or NAS, is with Firewire. Using a shared Firewire 800 disk that supports 2 separate servers at the same time. And then use this Firewire disk as shared storage. This is not supported by Oracle for production use - but past support notes did say that this is a config that can be considered for a dev type RAC. 
    If the 2 servers do not support Firewire 800, then 2 x Firewire 800 PCI cards (and cables) are needed, in addition to the Firewire drive.

Maybe you are looking for
