Slow Dev Machine, DBA help

A question for all you experienced DBA's.
We have about 5 to 6 schemas in our dev database and most of
them have prod data in them so that's a lot of records. All this
is on one machine. Things are extremely slow, when a forms query
is run or something like a package is looked up through Toad(a
facility to look at database objects).
In general what are the scenarios or methods to speed up the
database, increasing size or moving things onto different
machines or test schemas. Could you please comment on this. I
don't have Tom's e-mail address, I wanted to get his opinion
also, just from a standards point of view, maybe you can forward
this to him also.
Thanks for your assistance.

Can you provide the following informations:
1. How much RAM has this machine
2. Which OS ? (NT/UNIX)
2. How big the SGA (shared_pool_size, buffer_cache,
library_cache) (it's in the init.ora)
3. What database version ?
4. How many concurrent user ?
Regards,
Thomas

  • SUPER SLOW TIME MACHINE PLEASE HELP!!!!

    i have 2 external hard drives
    1TB LACIE & 1TB FANTOM DRIVE
    i have tested both and both do the same when TM kicks in EVERY HOUR it takes 48 mins to back up 100G an d completly slows and shuts down programs like itunes safari etc. to the point i cant do any work. i have tried both drives alone and they both do the same thing PLEASE HELP!!! i cant take it any more.
    michael

    Hmm. Are you changing 100 GB of data every hour?
    Do you use any virtualization software (VM Fusion, Parallels, Virtual box)?
    Do you use Entourage?
    We might see something in your logs. Download the Time Machine Buddy Widget here:
    http://www.apple.com/downloads/dashboard/status/timemachinebuddy.html
    And post the information for the most-recent backup. Make sure you get all the lines--they might overflow the window.

  • Report Generation working on Dev machine but not on Deployment + Lessons learned

    I don't do deployments very often with Teststand. But I have to say, I learned a lot from this one from trial and error and help from the message board. I have got my deployment to final work (almost) with these lessons learned:
    1. Create a base installer for the engines and drivers, that way if you need to update it is much smaller.
    2. Dont install Teststand before Labview on a new development machine (not related to this deployment but I did learn that)
    3. Don't have your Testexec window open, alter the Station Globals, then close the window. It just puts them back to the old version (probably my biggest problem).
    4. Paths are extemely important.
    I think I have figured it out with much time involved and kept notes of what I have done for future. The ONLY issue I have left is this below. My dev machine works as it should but when I deploy, it does not. FYI- I manually copied over Station Globals, Process model, and Testexec. DO I need something else?
    I create serial numbers for my UUT's in the proceses model. It all works fine in development. The serial numbers are generated and the UUT filename is titled [023232232].txt and changes per unit. The path for example lets say is C:\Users\Ryan\Desktop\temp.  A logfile is generated for each and put in that folder.
    When I deploy, it does something different. Instead of putting the files into the temp folder, it errors out saying it is in use. If I delete the temp folder, it creates a file called "temp" which contains my text logfile. This file just keeps getting overwritten.
    Any ideas on this?

    Hi SimpleJack,
    One way you can ensure that the Report Options you want to have stay with your sequence file is to actually override them using a Sequence File Callback.  I have attached a link to a KnowledgeBase article that walks you through how to add the ReportOptions callback to your sequence and programmatically set the options that you would normally set by going to Configure»Report Options from the Sequence Editor.  
    Also, to ensure that the correct Process Model is being used with your sequence file after distributing, you can set the Process Model within the Sequence File Properties.  This can be found by going to Edit»Sequence File Properties, and then going to the Advanced tab.  I have attached a screenshot of this window below, as well.  From here, you can set the Model Option to Require Specific Model, which especially comes in handy if you are using your own custom Process Models.
    I hope this helps, SimpleJack!  Have a great day!

  • When is Apple going to fix the problem with slow Time Machine backups with Mavericks?

    I have been with Apple tech support and they got my Time Machine working by doing a spotlight re-indexing and a safe boot.  This worked for about three days and I am back to very slow backups.  It is impossible for Time Machine to back up every hour when it takes six hours to do the back up.  I don't want to take hours to re-index with spotlight all the time.  I think taking six hours to do an incremental backup is a bit much.  I see that there are many people that have this trouble and it all started with an upgrade to Mavericks.  The question is when is Apple going to fix this problem of slow backups with Time Machine for Mavericks.  I have wasted more time than I care to.  I am think of going back to Windows.  I need good solid backups of my machine and Apple has taken it away with the new Mavericks. Oh, I am using the UBS 3.0 connection so the drive should not be the problem.  Also this has occurred in about the last five months, so I am not sure this problem was in the original Marvericks.

    Allen Thanks for your reply.  All I can say is several months ago Time Machine quit working in a reasonable manner.  Right now I have a Time Machine backup that has been running all night and still has three hours to go to backup 6 GB of data.  I am using a OWC 1.5 TB drive connected directly to my MacBook with a USB 3.0 connection.  In the resent past I have added Dropbox, GoogleDrive and a MAMP server on which I am using a program called Learning With Text from Sourceforge.  There have been a lot of questions on the forum about people having very slow Time Machine back ups, so it appears to be a general problem.  I should also state I am getting this very slow backup after doing the Spotlight re-indexing and the Safe Restart procedure that was told to me by apple support.  I have a 750 GB drive in my MacBook Pro which I am constantly trying to keep at a 5% level of free space.  This might be a problem also.  However, I am working on a lot of things and like to have a lot of things on my drive.  Also the heavily loaded drive has not be a problem in the past.  This slow backup business started about three months ago, so something has happen in a very short time period.  Now it seems even the procedure that Apple support gave me is not working.  Currently I am in China and it is difficult to interact with Apple support to solve this problem, but because I am in China having my computer backed up is critical. I have run the EtreCheck and am attaching the results below. I would appreciate any suggestions.  If necessary I will clear out more of my hard drive if that appears to be a solution.  The Time Machine drive was recently reformed so I only have a few backups on it.  I also don't run the Time Machine all the time as I don't want multi-hour backups running all the time.  I run it every few days.

  • Troubleshooting Slow Virtual Machines

    Friends:
    I am struggling with very slow virtual machines.
    I have Windows Server 2012 installed on a Dell T620.  It has two Intel Xeon E5-2650 2.00GHz chips (20M Cache, 8.0GT/s QPI, Turbo) and 64 G of 1600 MHz RDIMMS.  It is set up with two RAID arrays (RAID 1 for OS with two 300G 10k SAS drives; RAID
    5 for server stuff with four 600G 10k SAS drives) running on a PERC H710 Adapter RAID Controller (512MB NV Cache).
    There are two virtual servers running on the box.  One is the domain controller and the other hosts a SQL-based practice management program.  The "physical server" hosts HyperV etc.
    There are 5 or 6 virtual workstations, each running Win8.1E with one virtual CPU and dynamic RAM allocations of up to 8192MB.
    HyperV has two virtual switches ("RDS Virtual" and "Intel I350 Gigabit Network Connection - Virtual Switch").  (I don't actually know why it is set up that way.)
    I wonder whether anyone can help me trouble-shoot my poor performance?

    Hi MicahS,
    " There are 5 or 6 virtual workstations, each running Win8.1E with one virtual CPU and dynamic RAM allocations of up to 8192MB. "
    First , I would suggest you to try to allocate more host CPU resources to these VMs .
    To narrow it down ,  you can use performance monitor to check specific host resource  .

    RE: "P.S. I  found it aggravating that I couldn't copy and paste text  here, it wanted me to insert as a link or an image, how do you insert plain  text?"
    I take it you tried using the "right click" menu?   That doesn't seem to work, as you noted, but, you should be able to paste text by pressing your CTRL key  and while holding it down, press the "V" letter  key.
    CTRL + C = COPY

  • Time machine restore help

    I've recently been having issues with my early 2008 black Macbook. I ran the apple HW diagnostics and determined it is a bad hard drive. I went out and bought a new 500GB SATA HD, and attempted to restore my system using a Time Machine backup. I booted into the Leopard Disc that came with my computer, formatted the drive, and ran the Time machine restore. Everything appeared to go fine (took about 2 hours, no error messages). However, after the machine rebooted and attempted to boot into OSX an error similar to this popped up. http://img149.imageshack.us/img149/7792/pict0017lo8.jpg
    Any thoughts as to why this is happening? I don't really want to start over with a clean install, that's why I have Time Machine!
    Other information:
    My computer originally had Leopard, and was upgraded to Snow Leopard.
    I have boot camp setup on my mac for Win 7. (I know this isn't backed up or restored as part of a time machine backup, which I'm O.K. with.)
    Thanks in advance for all your help.

    Any number of possibilities. First, did you prep the drive properly:
    Extended Hard Drive Preparation
    1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.)
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    Any brand new drive should be setup per the above because they usually are configured for use on PCs rather than Macs.
    Second, depends on how you went about the process of restoring your system. Select Mac Help from the Finder's Help menu and search for "time machine." Look for an article specifically about performing a full system restore. Also, see User Tips for Time Machine for help with TM problems. Also you can select Mac Help from the Finder's Help menu and search for "time machine" to locate articles on how to use TM. See also Mac 101- Time Machine.
    What you saw was a kernel panic screen. Panics at startup may be indicative of a hardware problem. You might give this a try:
    How to run hardware diagnostics for an Intel Mac
    Boot from your original OS X Installer Disc One that came with your computer. After the chime press and hold down the "D" key until the diagnostic screen appears. Run the extended tests for a minimum of two or three hours. If any error messages appear note them down as you will need to report them to the service tech when you take the computer in for repair.
    Some "common" error indicators:
    SNS - sensor error
    MEM - memory error
    HDD - hard disk drive error
    MOT - fan error
    To assure the problem isn't with your backup you might consider installing OS X by itself. If all is OK, then you can complete the TM restore using Migration Assistant.

    If it is truly lost, Deleted, then you are basically SOL. Unless you do have a recent TM backup that has that file included.
    As for recovering it from TM do a search for Pondini TM FAQs.

  • MBP takes several minutes to start...  then very slow... HELP!

    This is a duplicate of a post I have in the MBP forums, but was suggested to me that I may want to post it here as well.....
    My MBP is coming up on 3 years old this December... Since upgrading to Leopard in early summer this year the system seems rather slow... especially starting up. It takes 3+ minutes usually. I didn't do a "clean", reformatted install with the OS install (which I may do once I back up my entire drive). I'm using approx. 70 gigs on my internal HD and the system states nearly 35 gigs availible... I have run Tech Tools Deluxe and Maintenance and they verify all is fine. I ran "sudo dmesg" in Terminal, and this is the report:

    I'd like to clean up my MBP and get rid of anything that is not needed or that may be slowing the machine down.... trying to get it to run faster, like when it was new.....
    ...what am I missing? What else should I do? Should I just do the reformat install of the OS once I back up to Time Machine?
    I should add that although I usually have a few devices connected to my USB/ Firewire ports, for the above test, I made sure nothing was attached to my MBP.
    Thanx,
    Tony

    I'll try. Have you tried basic maintenance? How much ram is installed?
    Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
    Select your language.
    Once on the desktop, select Utility in the menu bar.
    Select Disk Utility.
    Select the disk or volume in the list of disks and volumes, and then click First Aid.
    Click Repair Disk.
    Restart your computer when done.
    Repair permissions after you reach the desktop-http://docs.info.apple.com/article.html?artnum=25751
    Check your login items. Check to see which items you can eliminate or disable.
    If you have Diskwarrior, Techtool Pro or Drive Genius run them directly from the disc.

    Hi internet on my Mac(OS10.9.1) suddenly became very slow.  Could somebody help me?  Thanks.

    Try resetting everything:
    power down everything: modem, router, and computer
    power up each item in turn in the same order: modem, router, and computer. Let each power up completely before moving on to the next.

    mikheart,
    if you haven’t done so already, download and install EtreCheck. Please include in your reply the output produced from a run of EtreCheck.

  • Yosemite made my MacBook Pro so slow !! Need help ? what is the solution?

    Yosemite made my MacBook Pro so slow !! Need help ? what is the solution?

    I've ran a benchmark on my Mac (iMac early 2009). Performance of Yosemite in general was about the same as Mavericks. But that can be different on other Mac's of course. Safari is mostly a bit slower. It's recommended you clean your old internet-caches and then restart Safari. (you can use a little app called CCleaner to do that). That might make a difference. Speed-issues are usually solved in the first and second update of OS X.

  • Oracle DBA Help

    We have an Oracle 9i Database Standard Edition that is in production for about 3 years running on Windows 2003 Server Standard Edition. Our company does not have Oracle DBA. When we purchased Oracle license we didn’t sign up for Oracle Support.
    If something goes wrong with Oracle Database, if we could not figure out the solution on our own, is there any company that provides Oracle DBA help on a contract basis?
    What happens if we get internal errors in the database? Can we still contact Oracle Support?
    Please advice.

    #1. When you purchased Oracle Licenses, I guess Oracle would have provided (Support Identifier or CSI numbers), with that you should be able to create accounts/access with METALINK, which is one form of support Oracle provides. 99.99% of the day-to-day problems are resolved via metalink, oracle forms (like this) and other discussion threads.
    #2. But if you want Oracle personnel onsite, then it needs a different contract or support level, which is very expensive in my opinion. There used to be different support levels like platinum, gold, silver etc., I'm not sure of the classification now, better contact Oracle for additional info.
    I would highly recommend for #1, check the cost involved in #2 compare that with that of hiring a part-time/remote DBA, and see which one works better. If your database is not mission critical, configuring proper back and restore would help bring your database up, but with some downtime.
    Hope it helps,
    Babu Rangasamy
