• What are the effects of the clearing the browser Cache?

  What are the effects of the clearing the browser Cache?

  Caches to store a copy of the page Web that you visit to speed up the loading of the page even when you revisit the page.

  Once you empty the Caches, pages must be again downloaded from Web sites.

  With higher bandwidth available now, is not a problem.

  Sometimes these caches can get damaged and a troubleshooting step

  You can clear those without causing any problems.

  What applications to use to clean the unwanted cache? I doctor battery now, but it would be nice to share some ideas on the subject. IPhone 6, last updated. Thank you

  There is no apps that do this on an iOS device. And battery doctor causes more problems than it solves.

• What are the channels of meter on SMU-6361 pinout diagram

  Hello

  I've defined three channels of counters to help assistant DAQ for the SMU-6361 (ctr0, ctr1, ctr2) jury. I don't see any explicit labels on the pinout for the SMU-6361 card diagram indicating where are these counters. Can someone tell me what are the pins / labels on the diagram pinout for these counters?

  Thank you very much

  Hi Larrage,

  The best way to find the default pins use the DAQmx help file. You can reach to the MAX by clicking Help > Help topics > NOR-DAQmx > NOR-DAQmx help. In the help file, you can search for 'Connect signals to Counter' and click the link for the series of cards you have (series X in this case).

  In your case, the default meter terminals for ctr0, ctr1, output and ctr2 would be 12 PFI, 13 and 14 of the PFI PFI, respectively. Counter (for edge counting) entries would be 8 PFI PFI 3, PFI 0 to counters of same. You can change the terminals of input/output for counters in your VI or MAX, but these are the default values for the card.

  What are the files safely remove old projects to make my Media and Disk Cache? I use Photoshop and first, and when I installed After Effects, I got a message saying I needed free memory in this cache.

  Thank you!

  Hello

  Default location:

  Windows - "C:\Users\User_Name\AppData\Roaming\Adobe\Common".

  Macintosh - ' ~ / library/ApplicationSupport/Adobe/Common '

  Inside this place, you will find 2 files - 1. Media cache and Cache files for multimedia 2.

  If these two folders, trash, it will clear all the previous Cache.

  You can also do this in Premiere Pro, select Preferences/Media/Clean.

• Opening 5 LR I see "Lightroom has encountered an error when reading the preview cache and need to quit."  I deleted the folder Preview Cache completely (saved).  What can I do next to load Lightroom?

  Anybody out there can help get LR works again.

  Open LR 5 I see message "Lightroom has encountered an error in its cache of the preview reading and needs to stop smoking".  I deleted the folder Preview Cache completely (saved).  This does not solve the problem.  What can I do next to load Lightroom?

  If you remove the preview cache folder and the problem persists, then most likely you have found the wrong preview cache (it's for a different catalog previews) and you must find the right cache overview. You should use the search function of your operating system to find all files whose name ends with Previews.LRDATA and remove each of them until you can open your Lightroom Catalog.

• What is in the buffer cache

  Hello members,
  
  I'm trying to understand why some batch repeatedly not pio, I expect.
  
  One thing keeps popping up; Is it possible to see what is in the buffer cache. I can query v$, but not x$. Version is 10.2.0.3
  
  Something in the lines of what segments has how many blocks in the buffer, as

  SEGMENT_NAME                     BLOCKS
  ---------------------------- ----------

• What is the secret behind the cache level?

  Hi, I have a question about cache levels...

  OK, as we know, Photoshop creates several (smaller than the original) preview images to show the effects and create histograms. So, I think that if I choose the cache level 1 in the preference window, Photoshop does not any glimpse and it always displays information according to the original file. Is this wrong?

  But this isn't the case, I see. I updated my cache level 1 and it still shows the histogram for level 3 of the cache.

  So, my question is... What is the secret behind the cache level?

  There is a bug with preferences level underneath Windows.

  Try to set in the 32-bit application, then leave then to revive the 64-bit application.

• What is the difference between cached and no cached TT tables

  Hi all
  
  I have three users in my Timesten
  
  User Admin 1.TimesTen - cache
  2 - cacheuser user cache manager
  3.cbs_owner user schema (which is the same name as the user of oracle schema)
  
  
  I have a few groups of cache in timesten for oracle tables, I created some tables on user schema TTs to compile tables pacakges.these not associted with groups of cache;
  
  
  My question is what is the difference between cahed tables (tables associted with cache groups) and not cached (associted with any group of cache) TTs schema user, nice tables want to help me
  
  example-
  
  Command > tables;
  
  CBS_OWNER. ACCOUNT_SUBSCRIBER / / table belongs to the Group of cache
  CBS_OWNER. OFFER_REF / / not belogs to any group of table cache
  
  
  
  Thank you

  I just started to investigate TimesTen... and I think that the cache groups allow you to replicate data to and from Oracle. for example
  -Group of cache Read-Only: spreading tables cached in Oracle to TimesTen.
  -Group of asynchronous/synchronous cache: spreading the Oracle data.
  -User managed group cache: no automatic update or spread.

  No cached tables do not have the features of spread.

• What is the difference between the CACHE and the PIN code?

  What is the difference between the CACHE and the PIN code?

  Cached, it's when you specify CACHE as part of a CREATE or ALTER an object to say Oracle when the blocks are retrieved this object these blocks should be put to the most recently used end of the LRU (least recently used) list in the buffer cache when a full table scan. Under normal circumstances, when the blocks are retrieved in memory, in that they are placed least recently used end of the LRU list. This means that the data that was most recently viewed typically will remain available in the cache buffers for awhile. Therefore, subsequent runs of the same query should find these blocks already in the buffer cache and not to recover disk again. When you use the CACHE, you say you want to put the blocks retrieved at the end of the list, which means that they will be the first blocks "aged" off the buffer cache when more space is needed.
  A few reasons to use the CACHE are:
  (1) for tables of small (only a few blocks that must be read to retrieve the entire table).
  (2) when you do a select statement returns a huge amount of data, and you do not necessarily have if wait for the query to run any time soon. In both cases, you give Oracle an opportunity to eliminate the blocks quickly to make room for more 'necessary' blocks instead of having to follow in the LRU list.

  Pinning is when you want to keep the objects in memory and to prevent them from being aged by the normal mechanism of the LRU. You use the INVALIDHTOMEH to "pin" PL/SQL code in memory, so that users are not experiencing intermittent slowdowns when code gets years out of the shared pool and must be recharged.

  The bottom line is that caching can blocks be moved quickly while pinning retains the information in memory to avoid the re-loads.
