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?
Thanks,
Waheed.
Get some more disk and move some of your datafiles to the new disk.
or
See if you have unnecessary archived redo log files. If so, get rid of those that are older than the oldest backup you keep.
or
See if your audit files, trace files, or alert log are taking up too much space. If so, move them elsewhere or delete them.
or
See if you are accumulating data load files that you can get rid of.
or
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

Hi,
I have windows 2008 R2 64 bit OS and database version is 11.1.0.7.0 64 bit ...
I got the below error via EM.

1.Can any one tell how to trace this warning and where to check for this alert ?
2.what is the meaning of Disk Utilization for 0 ?
3.How to identify the problem and resolve the issue in this case ?
Thanks & Regards,
Vikash (Junior DBA)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.
Thanks,

Enterprise manager alert on disk utilization
hello..
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?
thanks,
peacockWell, 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 10.2.0.2.1
3. Patch agent and oms to 10.2.0.5.0
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!
Problem:
- 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 (%)
Disk Device 0 C:
Severity Critical

Message Disk Utilization for 0 C: is 587.86%, crossed warning (80) or critical (95) threshold.
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 disk array is in a RAID 5 configuration running 10k SAS drives
- 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?It may be related to Bug 8677212: BACKUP INFORMATION FOR SOME DATABASES SHOWS INCORRECTLY
Although bug info says it for HP-UX, I've also seen the same problem on Grid Control 10.2.0.5 running on Solaris.
You may want to apply 10.2.0.5.4 Grid Control Patch Set Update (PSU) [ID 1139563.1] to fix it.

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.
Hope it helps. -
Disk Utilization false alarms from EM dbconsole
Hi,
I have a 10.2.0.1 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?
ex.
Name=op1t1tsr
Type=Host
Host=op1t1tsr
Metric=Disk Utilization (%)
Disk Device=1 E:
Timestamp=Jan 27, 2008 2:31:18 AM CST
Severity=Critical
Message=Disk Utilization for 1 E: is 99.97%
Rule Name=Host Availability and Critical States
Rule Owner=SYSMANNo, 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. -
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?
Diego de Azevedo IT Analyst - MCSE, MCITPGood 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.

Here are the examples of the log entries for Event ID 9017

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.

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?
Thanks!!
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?

Hello All,
Since we installed the latest Patch Cluster patch our disk utilization has shot up substantially. Is there anyone having same experience? If you do, could you please help us to identify some areas to take a look?
Thanks very much.
Yihi again. i just fixed my problem. apparently when i unzipped the file and then burned it onto cd...the data got corrupted. i fixed it by copying the zip file onto cd and then extracting the patches onto the solaris machine.

I saw this message when I was doing a Repair Disk Permissions-
Warning: SUID file "usr/bin/quota" has been modified and will not be repaired.
Is this something I should be concerned about?I was booted into my VERY clean and fully updated 10.5.7 install last night, and just for kicks ran Repair Permissions. For comparison purposes, in my "working" system, which is still at 10.5.5, and where I have not run a fair number of other updates either, here's the total number of advisories in Repair Permissions:
Permissions differ on "private/var/log/secure.log", should be -rw------- , they are -rw-r----- .
Permissions differ on "Library/QuickLook/iWork.qlgenerator/Contents/CodeResources", should be -rw-rw-r-- , they are lrw-rw-r-- .
Group differs on "private/etc/cups", should be 0, group is 26.
Permissions differ on "private/var/spool/cups/cache/rss", should be drwxr-xr-x , they are drwxrwxr-x .
In 10.5.7 the situation is quite different: there are a raft of notices about files having been replaced with a symbolic link in Front Row, iTunes, the Media Browser, and iPhotoAccess. These are all the result of Apple's most recent Media updaters.
There are also new SUID notices:
Warning: SUID file "System/Library/Filesystems/AppleShare/afpLoad" has been modified and will not be repaired.
Warning: SUID file "System/Library/PrivateFrameworks/DiskManagement.framework/Versions/A/Resources /DiskManagementTool" has been modified and will not be repaired.
Warning: SUID file "sbin/umount" has been modified and will not be repaired.
Warning: SUID file "bin/rcp" has been modified and will not be repaired.
Warning: SUID file "usr/bin/quota" has been modified and will not be repaired.
Warning: SUID file "usr/bin/rlogin" has been modified and will not be repaired.
Warning: SUID file "usr/bin/rsh" has been modified and will not be repaired.
These strike me a bit peculiar since the SUID bit is set on ALL those in 10.5.5, where Repair Permissions makes no comment about it, and there has been no change at all....except evidently the database used by Repair Permissions no longer seems aware of the files' status.
Finally, both sets of Repairs complain about the group admin having read access to the secure.log file. I can't imagine why.

EM Alert: Critical: server - Disk Utilization for 1 D: is 99.8
hello!
in the last day's i receive the following error message every 2 or 3 hours:
Name=server
Typ=Host
Host=server
Metrik=Disk Utilization (%)
Disk Device=1 D:

Nachricht=Disk Utilization for 1 D: is 99.81%
Regelname=Host Availability and Critical States
Regeleigentümer=SYSMAN
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!

CSV Volume low on disk space warning alltough the space isn't used (VSS?)
HI Guys,
we are running a HV-2012 Cluster. most of the VM's are backuped by DPM 2012 r2.
Recently i noticed some "CSV low disk Space Warning" withing SCOM.
Today i looked at one of the CSV's.
The Size is 1800GB and if you look at the Size of all the Folders on the Volume within the Explorer they are 1250 GB.
After that i looked a the Failover Cluster Manager -> Storage -> Disk: This console states that there are only 36GB Free on the Volume.
My guess is that the VSS Snapshots use up the Disk-Space? But if i do a vssadmin list shadowstorage
only drive c is displayed.
Could this end up in a Problem or is the vss Space freed automaticly?
Or is there something else wrong?
Anyone a clue on this?
regards
StefanFirst thing is that you're running out of space and need to move quickly to make space while you figure this out. When you run out of space, the VMs will shut down.
How many VMs you have on that CSV and many VHD(x) disks you have an the CSV? Another question that matters here is how fast is your backup for each VM?
Regardless of the backup software being DPM or any other VSS based backup, it works by creating a checkpoint of the VM, which creates a snapshot of its disks. A volume snapshot turns the VM disk into a read only disk and starts a change log disk (.avhdx)
file. The crash consistent read-only .vhdx file is then copied by the backup software agent from the host to the backup server. Upon successful completion, the agent deletes the VM checkpoint, which merges the disk snapshot, merging the .avhdx and .vhdx files
back into one file.
So, if you're backup time for this VM takes hours, during that time, the VM disk space usage can grow a lot more that what it would usually use. If you run out of disk space then, backup will fail, the VM will be suspended, and you cannot bring it online,
since the merge needs even more disk space.

Time machine files and disk space warning.
hello, i have ran into some unknown issues with my os x and even though there have been similar topics discussed i would like to address mine and i hoe someone can help me out.
1. I am not sure if I accidentally turned on time machine or not , but at some point when i restarted a computer i noticed different folders and files that i have not created myself on my HD such as
.com.apple.timemachine.supported
.fseventsd
.hotfiles.btree
.Spotlight-V100
.Trash
.vol
var
etc
tmp
I do not know if this folders are safe to delete, since i am not using time machine.
2. Trying to download rather big file 34gb i received numerous warnings that my disk isfull, and it is not. i have 105GB used and 126GB free, also I am using 4gb RAM. so there should not be a problem. I saw a few topics regarding disk space warning, that were suggestinng that the user runs an application which shows where most of HD is used.
I cleaned a few stuff, but still, how can I prevent from this warning to appear.
Thank you for any suggestionscan i hide them?
Update: found terminal command to hide the successfully.
i ran verify disk and verify disk permissions and everything is OK.
