• When Adobe flashplayer wants to store data firefox won't let me respond to the dialog box? / flash player fiadobe settings dialog boxes not reponding

  After you install Adobe Flash 14.0.0.0.25 when I go to a site that wants to store data locally, I am presented with a dialog box that gives me options: allow, deny, specify the isite. However, no matter what I click nothing happens. It's almost as if Firefox is not 'see' the click. I went into settings Adobe manage and added that the site as being approved, but it did nothing...

  Best is to allow a Flash local storage in the world and use the default values.

• ZBOOK 17 - Flash Cache & general system failure

  Greetings,

  History:

  On my first install of windows on my 17 Zbook, the operating system installed the system reserved on the flash SSD cache partition. I thought I'd do a reinstall when I ordered and installed a 1 TB SSD. I removed all hard drives and flash installed the operating system cache, then turned off the computer and re-installed the cache flash. Now when I try to boot it gives me 5 flashes on the caps/NumLock with a pretty black screen.

  Has anyone encountered this before? All I could do to fix it? Thanks in advance,

  Ryan

  Thanks for the reply. I'll be sure to do that next time.

  I eventually found how to fix it. I removed all the readers, disconnected from all power and then removed the BIOS battery. He gave some time, clinging to power, and she came back to life. Of course he gave me some error messages, but after removing the power again and reconnect all devices (the ssd of 32 GB samsung flash cache included) then turn it on, everything was back to normal.

  No idea why she wanted to play dead but at least he's back running.

• 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.

• 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.

  Tim

  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.

• Question about smart flash cache

  If my entire db is less than the amount of smart flash cache that is available, Exadata would automatically cache entire DB in smart flash cache?
  I understand I can say Exadata at the tables of the PIN in the cache but just curious if Exadata would on its own in this scenario.
  Thank you.

  No, it not being cached everything simply because the DB is longer than the Smart Flash Cache. Caching is performed because of access to data, so frequently accessed data will be cached. Given at the cold end of the LRU algorithm gets years off and replaced.

  It is very similar to the DB buffer cache - you don't expect all your data to cache simply because the cache DB is greater than your data. However, if the frequently accessed data can all be cached, it will be.

• 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.

• Cache initializer / reproduced preload of the region

  Hello

  In my application, I have a replicated region defined to contain the configuration settings of overall application that will be shared between all nodes in the data grid. I preload a set of default configs in this region using a class initializer of cache. This initializer will be defined in each node, since we intend to have the same node throughout the grid architectures. I plan to avoid having multiple nodes pre-fill the default configs using a DistributedLock on the region during the initialization routine and make a putIfAbsent() for each configuration value in the region.

  My question is when I want to start a new node in an existing network: at the start of this new node will try to call the initializer. Will be the existing configs in the grid that runs already replicated to this new Looper before execution of the initializer or after? If, after the will then configs located in the new node get replicated to the rest of the grid or the existing configs in the grid get replicated on the new node of will?

  Thank you!

  TMO

  TMO,

  The initializer will be called after the replication has occurred. In other words, your configs will have been replicated to the new node before the initializer is called.

  Oh. k. so, it is the function of Read Cache (vFRC) Flash of vSphere and nothing to do with VSAN

  check the diaries which is throwing this error.

  ESP: /var/log/hostd.log and log/var/log/vmkernel of corresponding calendar. This will show what is happening here

  You can check the following

• vpshere edition to use Flash Cache reading

  Hi all...

  Reading the information on this new feature of version 5.5, it seems very interesting, but comes standard on the Standard and Enterprise versions? ..... I say this because in the vmware site Web, in editions of comparison chart, appears as the "point" in the plu company...

  A welcome message...
