vpshere edition to use Flash Cache reading

• Expectations of reading Flash Cache

  I start looking for flash caching. We lack version 5.5 on Dell PE servers connected to a PS6000 EQ. We have been hitting our max IOPS fairly regularly on the equalizer. We have a few writing intensive VMs Windows doing statistical analysis and some Linux VM a web hosting infrastructure. The average ratio of writing on the EQ is high enough, usually 90%, because some of the Windows virtual machines are very active, while everything else is fairly inactive. When some of the Windows virtual machines get his job stat, we begin to see latency on web VMs, especially those that host the databases (as you know).

  I understand the flash read cache will not help high write workloads, but it would help individual web virtual machines who see some latency no - is that correct?

  Also, I am reading the guide of best practices flash cache, but I was wondering if anyone had advice from real world for the size of the cache on the VMS or thoughts on the use of some of the ssd for the swap of the host. If we put an ssd in each of our hosts, should set us aside a certain percentage for the swap to host?

  Thank you.

  Unless you have problems with memory capacity, I wouldn't worry too much on the caching of the swap host.  If you are out of memory, then consider adding more ram or evolution and the addition of several hosts.

  As for the flash cache, did consider you - PernixData - you can speed up both read and write performance, which gives to your configuration, I think that would be the type of solution, you should consider caching.

• I have Windows XP Home Edition and use Outlook Express for my e-mail. Is there a way to copy/send e-mail, favorite contacts and my photos on a Flash key?

  Open the address book in the old identity and file | Export | Address book (wab) to any location on your HARD drive that is easy for you. The office is very well. Then drag that to the flash drive.

  In IE: File | Import and export | Export to a file. Check Favorites | Next | Next | Navigate to a folder or the desktop and export. Drag the folder in the flash player.

  For photos, just right-click on the folder and drag it to the USB and copy here.

• All dynamic views for (Exadata) Flash using the Cache?

  All,
  
  Although it is one of the main points of sale of Exadata (especially of the X 3 from), I am struggling to find much information about our use of the Exadata Smart FlashCache (I'm under RDBMS 11.2.0.2 BP7 on a quarter V2-rack).
  
  I can check the FlashCache usage by checking if the object has been "pinned" to the FlashCache via DBA_SEGMENTS and I use FlashCache can check by querying a gv$ sysstat (and even v$ mystat), but are there other views that I could use? It seems a little strange for Oracle is not to enlighten the DBA on their use of this feature...

  Hi Mark,

  My colleague Christo Kutrovsky put in place a script smart to collect this info of storage servers and accessed as an external table: http://www.pythian.com/blog/whats-in-your-exadata-smart-flash-cache/

• Update 24GB flash Cache hard drive for some other SSD acceleration

  Hello Experts,

  I plan to buy-

  HP ENVY 15 t-j100 Quad Edition Notebook PC (ENERGY STAR)

  -With

  • 1 TB 5400 RPM hard drive
  • 24GB flash acceleration Cache hard drive

  What can I upgrade (/replace) 24GB flash Cache acceleration of the drive with some other SSD whose greater storage size on the line after a few days? for example 240GB Crucial SSD?

  Thank you.

  It's different. Any other animal. It looks like a wireless card. See below. What you could do with a standard 2.5-inch SSD is to replace the original main drive. If you could total of 240 concerts that would be OK. You will need to remove the disc from mSATA (aka WSSD) as it is useless in a WSSD Accelerator reader when you have a main SSD drive. I guess that I encourage you to wait and see how you like the stock configuration. The WSSD throttle control is very effective and can make even a 5400 RPM hard drive mechanics work almost as fast as an SSD.

  

• Flash Cache - what is it?

  Hi - I "m given to replace the HARD drive in 141na HP ENVy 17 and doing a little research before doing so. Some retailers say it has a SSD 8 GB and a 1 TB of HARD drive, while others do not.

  I've been looking at the specs on the HP site and it says it has a FLASH 8 GB CACHE and other research says this;

  "Flash cache is temporary storage chip NAND flash memory to allow data of queries for the data to complete more quickly..." A flash cache is often used in tandem with the slower hard drives (HDD) to improve the access time to the data. The form factor of the NAND flash is typically a the solid state drive (SSD), a PCI Express (PCIe) card or a module DIMM- base flash device installed in connectors of the server memory. "

  Does that mean that upgrading to an SSD will be have a limited effect (bearing in mind I've only will use to store the OS and a few programs like Photoshop top with all my work files on the 1 TB HARD drive or I am barking the wrong tree here.)

  All the advicde greatly appreciated.

  Chris

  The NAND flash cache is actually built into the hard drive, I'm pretty sure. I can confirm that if you go into Device Manager and view the description of the hard disk device. That means that when you remove the drive hard drive will also remove you the "flash cache. While hard disks with flash cache mSATA WSSD accelrator cache disks / improve performance they ain't nothing like a pure SSD main drive. The cache flash and other similar arrangements can accelerate sustained as an SSD read/write operations.

• Need advice from configuration to the flash cache multi-node RAC/ASM

  We have a database of CARS to work two nodes. We install a new fusion 640 GB flash card in each node. The is a double card, so that it shows up as two devices: / dev/fioa and/dev/fiob on each node.
  We have created two groups of private drives, one on each node. The Group of disks on node 1 is '+ FLASHCACHE' and the disk on node 2 group is "+ FLASHCACHE2".
  
  We have not found specific examples of how to configure the parameters of the init for flashcache on RAC/ASM. We guess that we must do the following. If anyone would be critical and confirm or suggest something different, we would appreciate it very much!
  
  "prod1.db_flash_cache_file ='+ FLASHCACHE/flash1"
  prod2.dg_flash_cache_file = '+ FLASHCACHE2/flash2'
  * .db_flash_cache_size = 600G
  
  Thanks for any advice.

  Hi Jim,.

  prod1.db_flash_cache_file='+FLASHCACHE/flash1'
  prod2.dg_flash_cache_file='+FLASHCACHE2/flash2'
  *.db_flash_cache_size=600G
  

  Your configuration is correct.

  Smart Flash Cache database is not shared across RAC nodes. It is private to each RAC instance. For this reason, each RAC instance must define its own local cache of flash file path. When the flash cache is managed by ASM, a separate diskgroup is necessary for each instance flash cache.

  You can use ALTER SYSTEM for db_flash_cache_size set to zero to disable the flash cache. Alternatively, you can use ALTER SYSTEM to deliver the flash cache to its original size to reactivate it.

• TimesTen VS smart flash cache

  Hello
  
  I know that Flash Cache is slower than RAM, but can we say that doesn't cache smart flash the same work as the Oracle TimesTen Database Cache?
  Wrong or right?
  
  Thank you very much for helping me in my understanding.
  
  Edited by: 905160 Dec 30. 2011 00:58

  Bad :-) Smart Flash Cache is still in the storage layer and so does nothing to eliminate the code path heavy of a disc centered on the RDBMS. One of the main advantages of TimesTen is there a short circuit code path a lot thanks to its simple design and optimizations in the memory. There is a large part of the improved source performance. Also smart flash cache does not all access operations, but only those that use the smart cache.

  Smart Flash Cache is a great way to help the performance of a focused database on disk and it is used wisely in the Exadata buffer. But you should consider not equivalent to, or a substitiute for, cache TimesTen in-Memlory database. These are very different things, work very differently from each other and offer different benefits.

• Possible to make an element editable for some users and read-only for others

  Is it possible to make an element editable for some users and read only for others?
  
  I was able to achieve by catches of the select statement that I used to define an authorization scheme, placing in the State of read-only element. However, I would simply refer to the authorization scheme to use caching and to help keep things cleaner for future maintenance.
  
  Is it possible for a system of authorisation under a condition similar to the way point another element can be referenced by preceding with two reference points (e.g.: P1_First_Name)?

  I accomplished this in one of my applications by setting the value of a hidden Page 0 item on connect, for example P0_ACCESS_PRIVILIGES, and then use the feature 'Read only' integrated into the APEX for each article that I don't read for some users check the value of this element.

• YouTube and WebMs are weird when trying to play automatically (details inside), but using Flash to load videos on websites like DailyMotion works very well.

  It started a few days ago, possibly coinciding with the update to 41.0.1.

  If I upload a video on Youtube, or load a WebM, the video shows that it is set to 'play', as it is supposed to and it loads as usual, but does not in fact, time just 0:00. If I pause and re-activate it or move the timer, he plays as usual. Also, if I load a Youtube video from a referral link on the page of a video that I've played, this happens. This does not happen on sites like DailyMotion who only use Flash instead of HTML5.

  Is there a solution for this? Even if I had to force Youtube to play with Flash instead of HTML5, it won't fix problems with WebMs.

• Impossible to download files in Firefox, using flash uploader. Already reinstalled flash, works well in Chrome.

  I have a site where I can upload files to the site server using Flash - I have the latest Firefox and the latest version of the plugin Flash (uninstalled and reinstalled). "But the download fails - I get an unknown message of I/O. but only in Firefox - works fine in Chrome. I already ran the process of uninstalling/reinstalling Adobe and I also tried to run Firefox in Mode without failure and the problem persists.

  Hi Bilinbaja,

  I don't know if you use FTP to download the files, however, this error can sometimes refer to a hardware problem. Please try to turn hardware acceleration by clicking on an element using the flash plug-in and selection of parameters.

  Please let us know if this improves the performance as well as if this also happens on other computers, or if it still happens after you delete cache and cookies. Each browser has its own cache, Firefox's cache may also be longer. How to clear the Firefox cache

• Satellite Pro A200 - need Windows 7 driver for flash card reader

  I changed from Vista to Windows 7 on my Satellite A200-20N, and now I can't use the card flash inside Reader. I already looked for drivers, but I only find one for vista, also tried to install it, but failed.

  How I use my card under Windows 7 flash reader?

  Hello

  Unfortunately, I think you can use the Vista driver and normally they also work on Windows 7.
  Perhaps you can explain what it means not managed exactly

  In addition, you can try a new driver of another model of laptop card reader, e. g. Satellite A300.

  High temperature can be one of the many reasons why the laptop does not work correctly. You can check this by using like Everest Home Edition and similar diagnostic tools

  Corrupt system is the main reason why something is not working

• What is GUI and how to get the latest edition of the FLASH to download

  I said trying to download the latest edition of the FLASH and an error message came and said that he couldn't download a GUI

  GUI stands for graphical user Interface.

  I appreciate that you try to download and install Adobe Flash Player on this site: http://get.adobe.com/flashplayer/ or maybe some other website? What exactly was the message?

  What browser do you use? Adobe Flash Player can be installed only to the 32-bit version of the web browser. If you have Windows 7 x 64 it is very possible that you have started IE x 64 and you can't install Adobe Flash Player. You can find IE 32bits version by typing in the search box of the start 'Internet Explorer' menu and launching the appropriate version (not x 64).

  ...

  You can try to uninstall Adobe Flash Player using the uninstaller of this site: http://kb2.adobe.com/cps/141/tn_14157.html and then install if from scratch.

  ...

  You can also install another browser such as Firefox , Opera or Google Chrome and see does the problem also occurs in their case.
