Time Series Format of Operating System Statistics

On the AWR report we see the "Operating System Statistics" section.. since generating multiple AWR reports is daunting and takes a lot of time and I'm only interested on particular columns of dba_hist_osstat (where that particular section of AWR pulls the data)... I'd like to have an output like this:
SNAP_ID BUSY_TIME LOAD NUM_CPUS PHYSICAL_MEMORY_BYTES
244 6792 .23 1 169520
245 1603 .04 1 154464
246 28415 .05 1 5148
Problem is, the dba_hist_osstat values are stored as rows...
select * from dba_hist_osstat where snap_id = 244;
244 2607950532 1 0 NUM_CPUS 1
244 2607950532 1 1 IDLE_TIME 57153
244 2607950532 1 2 BUSY_TIME 5339
244 2607950532 1 3 USER_TIME 1189
244 2607950532 1 4 SYS_TIME 4077
244 2607950532 1 5 IOWAIT_TIME 2432
244 2607950532 1 6 NICE_TIME 0
244 2607950532 1 14 RSRC_MGR_CPU_WAIT_TIME 0
244 2607950532 1 15 LOAD 0.099609375
244 2607950532 1 1008 PHYSICAL_MEMORY_BYTES 300536
So I got this query to walk through all the SNAP_IDs with the following output. I'd just like to format particular columns like the one I mentioned (above) for the data to be more meaningful and to be easily loaded on excel for visualization. Well I can also do this on "Instance Activity Stats" (dba_hist_sysstat) and other stuff..
select
b.snap_id, substr(e.stat_name, 1, 35) as name,
(case when e.stat_name like 'NUM_CPU%' then e.value
when e.stat_name = 'LOAD' then e.value
when e.stat_name = 'PHYSICAL_MEMORY_BYTES' then e.value
else e.value - b.value
end) as value
from dba_hist_osstat b,
dba_hist_osstat e
where
b.stat_name = 'BUSY_TIME' and
b.dbid = 2607950532
and e.dbid = 2607950532
and b.instance_number = 1
and e.instance_number = 1
and e.snap_id = b.snap_id + 1
and b.stat_id = e.stat_id
order by snap_id, name asc
SNAP_ID NAME VALUE
244 BUSY_TIME 6792
245 BUSY_TIME 1603
246 BUSY_TIME 28415
BTW, try to generate AWR reports on a particular SNAP_IDs, the value you get from the query will be the same on the report...

Hi Jonathan,
Thanks for the input, I'll explore rewriting the query using those functions. But for now it serves the purpose of knowing/characterizing the workload, and also having a clear view of the capacity, requirement, and utilization without the hassle of generating AWR reports on each snap_id...
This will also be useful for visualization and predictive analysis..
BTW, I've used the following tables:
- dba_hist_snapshot
- dba_hist_osstat
- dba_hist_sys_time_model
- dba_hist_sysstat

  • Operating system statistics

    i want to know the operating system statistics like operating system name with version,memory,Number of CPU's etc.. from SQL * plus.
    Is there any view avaliable to get this information.My database version is 9.2.0.5.0.
    Thankx in Advance..

    Hi,
    you can use SELECT * FROM SYS.AUX_STATS$ to select the CBO System statistics, but there won't be anything about sqlplus version, number of CPUs, Memory etc etc.
    Use the OS funktions to do that - that's what there are for.

  • Does time machine back up operating system as well as files?

    i was told that if i did a time machine back up then i could boot from it and even restore it onto a mac with no os. is this true? if so how do i do it?

    Yes, it's true. But a Time Machine backup in Snow Leopard is not bootable. It must be reinstalled from an installer DVD.
    Only Time Machine backups made using Mountain Lion can be booted from the backup drive itself. In Mountain Lion Time Machine actually puts a copy of the Recovery HD onto the Time Machine backup drive.

  • Execution of Coded UI scripts with least possible test execution time in Windows7 Operating system using Visual Studio Test Agent 2010 without VS2010 installed

    Hi All,
    We are trying to execute coded UI scripts without Visual Studio installed. We are using “Visual Studio Test Agent 2010” for executing coded UI scripts without VS2010 in Windows 7, it is working fine. Also we verified executing the same script with VS2010
    Premium, it works fine as well.
    Here the challenge we are facing is with the Test execution time.
    When we run the coded UI script with IE11-Windows 7 OS-Visual Studio 2010 Premium it takes
    3min 36sec to complete the execution whereas with IE11-Windows 7 OS-Visual Studio Test Agent 2010  it takes
    6min 40sec for the same script to execute (which is almost double the time it takes while executing using VS2010).
    My question is what may be the reason for this difference? and how we can reduce the test execution time when running from Test Agent 2010?
    Kindly let us know what is the best practice to execute the coded UI scripts with least test execution time in Windows 7 Operating system using Visual Studio Test Agent 2010 without VS2010
    installed.
    Looking forward for your positive response.
    Thanks in advance..!!

    Tina-Shi, Thanks for the information.
    As you mentioned, we tried to execute the coded UI test using Mstest.exe in command on VS2010 Premium and checked on the execution
    time, there was a slight difference.
    Please find below execution time.
    Using Mstest.exe in command on VS2010 Premium/Win7 – 3.47 minutes
    Using VS2010 Premium/Win7 – 3.53 minutes
    Using Test Agent/Win7 – 7.3 minutes
    Also, I closed all the other processes in Task manager before starting up the execution.
    Still , I am facing the same Issue. Could you please suggest any other way to reduce the scripting time of coded UI script execution
    through Test agent 2010.
    Looking forward for your earliest response.

  • Time Capsule and operating system backup

    I recently purchased a MacBook Pro and the timecapsule for backups. My question is does the Time Capsule backup the operating system as well as files. I understood that it did but when I did my first backup it only took an hour. I have many songs and lots of photos on my hard drive.
    I worry that it didn't complete the backup.
    Any thoughts or sugestions?

    Yes. Time Machine, which is the software that the Time Capsule hardware uses, should backup everything.

  • Host operating system was experiencing significant paging

    Hello,
    I have a problem with many times discussing problem "Host operating system was experiencing significant paging but no particular root cause could be detected. Investigate processes that do not belong to this instance running on the host that are consuming significant amount of virtual memory. Also consider adding more physical memory to the host."
    My database run on Windows Server 2008 R2 and have 12GB of physical RAM.
    Oracle version is 10.2.0.4.0 and my sga and pga are:
    sga_max_size 4000M
    sga_target 3904M
    pga 1200M
    I try to find out something about this issue and read many blogs but unfortunately I didnt find anything which helped. Should this have something to do with the fact that on the server we have oracle database and terminal server with 30-40 users?
    Any advice?
    Thank you
    Martin

    I tried to get some information from ProcessExplorer but I didnt find anything that can cause this issue... Oracle runs as threads. You should be looking at the oracle.exe process and its threads, the size of Vmem, and the number of soft and hard page faults errors per thread.
    This should tell you whether there is a page swapping issue for Oracle processing, and identify the threads experiencing the problem. With the threads identified, the associated Oracle v$process and v$session can be identified and analysed.
    Could this paging fault make slowdown database? Page swapping can make any process slow.
    I mean when users try to insert, update or delete data from tables, response of database is slow, sometimes in few seconds - in Oracle Database 9i we doesnt have this problems...Invalid comparison. Not the same database (physically). Not the same database software. Not the same anything.
    Saying that a 9i database was fast and a 11g database is not, is like saying the old green car was fast and the new car, also green, should therefore also be fast.

  • Updating operating system and Aperture

    Hello,
    I have 2 questions. I'm currently using Aperture v1.5.6 on my MacBook Pro, OSX 10.4.11. I think it's time to update my operating system, but as it is 2 behind the latest, I'm not sure what to do. Do I have to do it in 2 stages (and buy both), or can I jump to the latest (Snow Leopard)?
    Also, If I update, I'm worried my Aperture version will not be supported. I'm a photographer, and want to be able to access all my Aperture projects I've created, through any version of Aperture.
    Can anyone recommend a process to upgrade both my operating system and buying a later version of Aperture?
    Many thanks.

    technically, you need to buy the Mac OS X box set to be totally legal. In reality you can just get the 10.6 update and it will update your Mac.
    I'm not sure about Aperture, though.

    Purchased a used macbook pro with Mountain Lion. My old Mac runs Snow Leopard is backed up to Time machine. How do I register the operating system to me and how do I use Time Machine to move my files to the new used computer?

    If you look at the User Tips tab, you will find a write up on just this subject:
    https://discussions.apple.com/docs/DOC-4053
    The subject of buying/selling a Mac is quite complicated.  Here is a guide to the steps involved. It is from the Seller's point of view, but easily read the other way too:
    SELLING A MAC A
    Internet Recovery, and Transferability of OS & iLife Apps
    Selling an Old Mac:
    • When selling an old Mac, the only OS that is legally transferable is the one that came preinstalled when the Mac was new. Selling a Mac with an upgraded OS isn't doing the new owner any favors. Attempting to do so will only result in headaches since the upgraded OS can't be registered by the new owner. If a clean install becomes necessary, they won't be able to do so and will be forced to install the original OS via Internet Recovery. Best to simply erase the drive and revert back to the original OS prior to selling any Mac.
    • Additionally, upgrading the OS on a Mac you intend to sell means that you are leaving personally identifiable information on the Mac since the only way to upgrade the OS involves using your own AppleID to download the upgrade from the App Store. So there will be traces of your info and user account left behind. Again, best to erase the drive and revert to the original OS via Internet Recovery.
    Internet Recovery:
    • In the event that the OS has been upgraded to a newer version (i.e. Lion to Mountain Lion), Internet Recovery will offer the version of the OS that originally came with the Mac. So while booting to the Recovery Disk will show Mountain Lion as available for reinstall since that is the current version running, Internet Recovery, on the other hand, will only show Lion available since that was the OS shipped with that particular Mac.
    • Though the Mac came with a particular version of Mac OS X, it appears that, when Internet Recovery is invoked, the most recent update of that version may be applied. (i.e. if the Mac originally came with 10.7.3, Internet Recovery may install a more recent update like 10.7.5)
    iLife Apps:
    • When the App Store is launched for the first time it will report that the iLife apps are available for the user to Accept under the Purchases section. The user will be required to enter their AppleID during the Acceptance process. From that point on the iLife apps will be tied to the AppleID used to Accept them. The user will be allowed to download the apps to other Macs they own if they wish using the same AppleID used to Accept them.
    • Once Accepted on the new Mac, the iLife apps can not be transferred to any future owner when the Mac is sold. Attempting to use an AppleID after the apps have already been accepted using a different AppleID will result in the App Store reporting "These apps were already assigned to another Apple ID".
    • It appears, however, that the iLife Apps do not automatically go to the first owner of the Mac. It's quite possible that the original owner, either by choice or neglect, never Accepted the iLife apps in the App Store. As a result, a future owner of the Mac may be able to successfully Accept the apps and retain them for themselves using their own AppleID. Bottom Line: Whoever Accepts the iLife apps first gets to keep them.
    SELLING A MAC B
    Follow these instructions step by step to prepare a Mac for sale:
    Step One - Back up your data:
    A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
    B. Clone to an external drive using using Carbon Copy Cloner.
    1. Open Carbon Copy Cloner.
    2. Select the Source volume from the Select a source drop down menu on the left side.
    3. Select the Destination volume from the Select a destination drop down menu on the right
    side.
    4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
    sure to opt for that.
    Destination means a freshly erased external backup drive. Source means the internal
    startup drive. 
    Step Two - Prepare the machine for the new buyer:
    1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
    2, Remove any Open Firmware passwords or Firmware passwords.
    3. Turn the brightness full up and volume nearly so.
    4. Turn off File Vault, if enabled.
    5. Disable iCloud, if enabled: See.What to do with iCloud before selling your computer
    Step Three - Install a fresh OS:
    A. Snow Leopard and earlier versions of OS X
    1. Insert the original OS X install CD/DVD that came with your computer.
    2. Restart the computer while holding down the C key to boot from the CD/DVD.
    3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.
    Optionally, click on the Security button and set the Zero Data option to one-pass.
    4. Install OS X.
    5. Upon completion DO NOT restart the computer.
    6. Shutdown the computer.
    B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because
    it is three times faster than wireless.
    1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
    Utilities window appears.
    2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button. 
    3. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click
    on the Erase tab in the DU main window.
    4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
    and set the Zero Data option to one-pass.
    5. Click on the Erase button and wait until the process has completed.
    6. Quit DU and return to the Mac OS X Utilities window.
    7. Select Reinstall Lion/Mountain Lion and click on the Install button.
    8. Upon completion shutdown the computer.
    *If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.

    All you need to upgrade the iBook for Tiger is another 128 MBs of RAM. It has both Firewire and USB ports. You do want to upgrade it for what you plan to do. The problem you may continue to have, however, may be due to the fact that the age of the computer is such the disk controller does not support hard drive volumes larger than 128 GBs, which is probably the reason the drive won't mount.
    The reason you get DU errors is likely because the drive was formatted using the Intel Tiger version of DU, while you were using the Jaguar version. That's a definite no-no.

  • Here is my question: Once my computer downloads updates I get the following line: loginwindow SleepWakeCallback. This has happened several times but now my computer lags so much it feels like I have a windows operating system.

    Please help, The problem started with this string downloaded, and now my iMac acts like it has a windos operating system with all the lag time I encounter. Any help with a possible solution would be greatly appreciated.

  • Best log file format for multivariable non-continous time series

    Databases or TDM(S) files are great, but what if you cannot use a database (due to the type of target) and TDM files are (seems) unsuitable because the data does not come in blocks of continous time series. What is the best file option for data logging?
    Scenario:
    The number of variables you are going to log to a file can change during run-time
    The data is not sampled at fixed intervals (they have been deadband filtered e.g.)
    The files must be compact and fast to search through (i.e. binary files with known positions of the time stamps, channel descriptions etc.)
    Must be supported on compact fieldpoint and RIO controllers
    Right now we use our own custom format for this, but it does not support item no. 1 in the list above (at least not within the same file) and it would be much nicer to have an open format that other software can read as well.
    Any suggestions?
    MTO

    I did some tests of the performance. For a months worth of data (2592000 rows) with 4 channels, I got the following results when reading all of the data:
    1. TDMS file written as blocks of 60 values (1 minute buffers):1,5 seconds.
    2. As test 1, but with a defrag run on the final file: 0,9 seconds
    3. As test 1 & 2, but with all the data written in one operation: 0,51 seconds 
    3. Same data stored in binary file (1 header+2D array): 0,17 seconds.
    So even if I could write everything in 1 go (which I cannot), reading a month of data is 3 times faster with a binary file. The application I have might get a lot of read-requests and will need to read much more than 1 month of data - so the difference is significant (reading a year of data if stored as monthly files would take me 12-18 seconds with TDMS files, but just 2 seconds with a binary file.
    Because I'll be writing different groups of data at different rates, using the  advanced api to just get one (set) og header(s) is not an option.
    TDMS files are very versatile, it is great to be able to dump a new group/channel into the file at any time, and to have a file format that is supported by other applications as well. However, if the number of writes are many and the size of each write is (has to be) small the performance gets a serious hit. In this particular case performance trumphs ease of use so I'll probably  need to rewrite our custom binary format to preallocate chunks for each group (feature request for TDMS? :-) ).

  • What are the supported Macintosh Operating System versions for IBM SPSS Statistics 18,19 and 20?   Question  I would like to know what are the supported Macintosh Operating system versions for IBM SPSS Statistics versions 18, 19 and 20? Answer  Please see

    What are the supported Macintosh Operating System versions for IBM SPSS Statistics 18,19 and 20?
    Question
    I would like to know what are the supported Macintosh Operating system versions for IBM SPSS Statistics versions 18, 19 and 20?
    Answer
    Please see the list below:
    - IBM SPSS Statistics 18 and 19 releases are supported on Apple Macintosh OS 10.5 (Leopard) and 10.6 (Snow Leopard) with Intel processor.
    - IBM SPSS Statistics 20 release is supported on Apple Macintosh OS 10.6 (Snow Leopard) and 10.7 (Lion) with Intel processor.
    - The IBM SPSS Statistics versions 18 and 19 are not supported on Mac OS 10.7 (Lion).
    THIS MEANS THAT TO USE LION ONE FIRST HAS TO UPGRADE TO SPSS STATISTICS 20.

    Whilst the 2012-02-15 edition of IBM's matrix does not mention Lion, a few users have noted that:
    • 18.0 can be troublesome
    • an updated version of 18.x should be better.
    Related files
    PASWStatistics_1 803_Mac_Patch.dmg and IBM SPSS Statistics 18.0.3.4 Hotfix Mac.zip are no longer available from the spss.com domain, and I could not find them in an IBM domain. If you download from unofficial sources, proceed with caution.
    Related pages
    In Apple Support Communities:
    • will PASW (SPSS) 18 work with LION
    • PASW statistics 18 crashes every time
    • Java Virtual Machine & SPSS 18 with a question from me.

    • Patching PASW 18 (or SPSS 18) for Mac OS X (Leopard, Snow Leopard, Lion) to version 18.0.3.1
    • and other sources, including one domain that I treat as reputable but I'll respectfully not share that link here.
    At a glance, you might find that 18.0.3.4 is compatible with Lion.

  • Why does the new operating system not delete the moved files from their original location - it seems like an enormous waste of space, time and effort to clean up every file once you've moved it

    Why does the new operating system not delete the moved files from their original locations - it seems like an enormous waste of space, time and effort to clean up every file once you've moved it - also, when transferring large amounts of files it becomes a very large problem remembering which files were transferred and which not.

    You're going to need to be more specific, as I'm not quite sure I understand what you're talking about.
    If you're referring to copying from an external hard drive or flash drive, and you want to actually move files rather than copy them, you can hold down the option key to force it to do a "move" rather than a "copy." This is not new behavior, though... the Mac OS has worked this way as long as I can recall (and I've been using it since 1984).
    If you're having a problem with trying to move files from one place to another on a single drive causing them to be copied instead, that is likely because of some permissions issue preventing you from actually being able to move them.

    Have been using Lightroom on my Apple computer for years. Now, ever since upgrading to Apple's  Yosemite operating system I get an error message (150:30) every time I try to open a lightroom file. Has anyone else experienced this problem?  Also how do I subscribe to Adobe's Premium Support? Every time I've tried (through contact support) I just get taken on an unending loop.

    I think we need a lot more information.
    Exactly what does the message say?
    Exactly what files are you trying to open?
    Exactly how are you trying to open them (what menu command or button or mouse action or keyboard shortcut)?
    And lastly, what version of Lightroom are you using?
