Slowness of the ASM

Dear team,
I made a new installation of Oracle RAC using Oracle Grid Infrastructure 11.2.0.3, included with the DSO, on 7 of IBM power servers. the installation was successful.

While creating storage on the database instance, I noticed that this process takes too long and the flow of the DSO is 0.07 Mbps (response time 450 ms), then a tablespace with 40 GB took more than an hour to create.

In addition, I also noticed a slow when opening enterprise manager, as if the e/s of the DSO is too low, noting that the storage is configured in RAID 10 and the ASM SGA_MAX = 272 M

I did a test of mounted file system on a LUN and copy a file with size 40 GB; I noticed that it goes too fast.

could you please help me to solve the problem.
Thanks in advance for your cooperation
Concerning
Elijah

  • How do I disable Adobe Flash - too many sites have Flash ads that slow down the browser unless an analysis.

    Some pages contain 3, 4, 5 or more adobe flash ads running at the same time, which slows down the browser a lot. Then, if you happen to have several tabs open, the browser is dragging virtually interrupted and many times is not responding at all.

    I would like to be able to choose whether or not a page can run flash content - not it be something that works all the time for each page, with the only option being to kill the plugincontainer process in taskmanager - who kills even the Adobe Flash elements you can watch; like a youtube video.

    Why is there not a way to disable Adobe Flash in the browser? I have updated Firefox and Adobe Flash, but nowhere is there at - it an option to turn on or off according to your needs.

    A control can be added to the Internet Options that you can set to have a page request before it is allowed to run the Flash content? Having that kind of control would GREATLY increase the pleasure of sailing on several pages.

    Any information on how to do it, would be appreciated.

    Hello, this is already possible in firefox: go to firefox/tools > addons > plugins and shockwave flash to Activategame. then the plugin will be disabled by default but can be enabled on a site-by-site basis.

  • Why FFx21, from the opening, thus creating three CACHE of INTERNET files duplicate (01, 02, 03 & tot'ng 12 MB) slows down the site?

    On the 'OPENING' Firefox for the web, there is an initial use of 12 + MB of use via INTERNET CACHE files. These files show up, when using CCleaner, as... \_CACHE_001, 002, 003 each with a size of say 4 096 Ko. The browser seems to "lag" - particularly visible when I type in one of the available search bars... I tap and then wait for the letter or the word to display. In addition, Firefox crashed several times since the upgrade to the latest version (ffox 21). I have two images CCleaner printscreen to show files so useful, but not sure how to enter them here.

    Hello, these are the files where firefox stores its cache - you won't need CCleaner (in fact, it will be only slow down the things that you have already noticed, given that these files must be recreated after the next startup of the browser), you can also clear the cache with the mechanism built into firefox: How to clear the cache of Firefox

  • Satellite C650 - is slow on the first day

    Got a new Satellite C650 two weeks ago. Everything on it runs very slowly.

    Abandoned entirely on Internet Explorer and positioned on Google Chrome, which helped, but it is nowhere near as fast it should be. I use a broadband wireless connection which works fine on other laptops in the House. I read that I should look at disabling some start-up processes that are not necessary but which? Toshiba has loads of their race and I don't have any idea what they are.

    I should add that I also installed BitDender antivirus software and that is the only addition I made.

    Any help would be appreciated.

    Hey Buddy,

    To be honest it is always difficult to discuss issues such as a series of portable computers slow down because nobody knows what exactly you were doing and what additional programs that you have installed.

    Done if you have installed another anti-virus software, make sure that the pre-installed McAfee of Toshiba is removed.
    If you have two antivirus installed, they will slow down the performance.

    You can also defragment the HARD drive. This can also increase performance.

    Finally and above all it s always advisable using the forum search. You will find a large number of discussions on this issue.

  • Slow down the Audio and keep beat related Sections

    Hello people,

    I have a song that I would like to remix and I all set beat matching.  When I go to slow down the audio I lose my bearings.  Is there anyway that I can keep the sections that I beat matched and slow down the audio so these sections remain?

    For example, that the song is 120bpm and I have this rhythm corresponded perfectly.  If I have a loop of 4 bars and slow down the audio I have more 4 perfect bars.  I want to be able to slow down the audio and still have my bars 4 faultless.

    I hope that makes sense.

  • Flex 2 network slows down the entire network

    I bought a Flex 2 a few weeks ago. Installed the software Office 365 and creative cloud by Adobe. Everything worked well on both networks, I connect to.

    Today, performance on the entire network is now gone to the dogs. At first, I suspected the provider or router so crossed all the routines of standard service (this disconnect, which reboot) again and again. Same face, deadly slow performance of several PC and Mac on the network.

    Then, I hit on the idea to close my Lenovo. Suddenly, network download speed of 2 MB/s and the ping from 2000 MS to more normal speeds returned.

    I restarted the Lenovo a couple of times, from 2, 4 GHz to 5 with the same result.

    At some point when I plugged the Lenovo directly into the modem (part of the diagnosis) direct speed seemed faster.

    Because the router works perfectly with all the other machines and I haven't changed a thing on it, and because the symptoms get carried away on the network when the Lenovo is cut, I can only assume that there is something to do with the Lenovo Flex 2 and how it communicates with the rest of the network.

    I should also add that I tried to plug an ethernet cable to make sure that it wasn't just a wireless thing. Still had the slow performance.

    I'm pulling my hair out over this, if I can't fix it, I can't work (no one in my office will be able to work) and will have to return the machine...

    Any ideas?

    Thank you...

    Thanks for the reply.

    After much pulling hair and analysis where the traffic was, it turns out it was a Microsoft cloud service a too aggressive drive that decided to download dozens of large files at the same time instead of in series. This excessive series of connections slowed down the rate of time and transfer of ping everything on the network. Disable updates for OneDrive during periods of work seems to have solved the problem.

    That said, working on this, I see that updates from Lenovo is continually a significant overhead. Do not understand why it takes so resources...

    Thanks again for the response...

  • Prevent the Beep.vi slow down the VI

    Hello

    I'm working on a metronome that should run for a period of x with a frequency of x. The time is in seconds and rate.

    Whenever there is the beet, the VI must make a beep. This can be done easily by the beep.vi, but the standard for the beep.vi is to play one system.

    This is a fairly long tone (10 of Windows). And so, I want to put my own frequency and duration of the beep.

    But when I change this in the beep.vi, the VI will wait for the set time (msec) before it continues the vi. If it slows down the whole VI.

    Is there a way to make the beep.vi a sound signal with frequency and duration that I put, without that it slows down the VI?

    Thank you!

    Have the code "beep" performed asynchronously to your hand VI: have the VI in another loop and use a queue / notifier to notify the loop when playing the main loop.
