• ReadyBoost will not use more than 2 GB 'Cache space used' on 4 GB ReadyBoost.sfcache file

  Windows 7 64 bit on a computer laptop 4 GB.

  I have a card SD of 2 4 GB dedicated to ReadyBoost, connected via USB2.   I tried to format the card as NTFS and exFAT and in both cases, Windows may correctly fill in the card with a ReadyBoost.sfcache file, which is about 3.8 GB (card is dedicated to ReadyBoost).

  The problem is that no matter how long the system running, perfmon displays 'Cache space used' is always less than 2 GB.
  He goes up regularly in the first ten minutes after enabling readyboost, then levels: less than 2 GB:

  (Of course the "put bytes in cache" are greater because of the compression.)   But it seems to use only about 1/2 of the 4 GB cache file.
  I tried to adjust to only use a 2000Mo cache file size, and then 'Cache space used' would not exceed 1.4 GB.

  Am I something wrong or bad what do the numbers mean or is it an inherent limitation of ReadyBoost due, for example, General fresh metadata in the cache file?

  As I frequently have max on my use of memory and I can not install more than 4 GB, I had significant performance gains when he might have already spent several minutes, beating the pagefile.   I hope to see even more benefits with a bigger Readyboost cache if possible.   I would also like to solve this problem before investing in a larger and more efficient card.

  Thank you and best regards,

  Hi Jeff,

  In some situations, you might not be able to use all of the memory on your device to speed up your computer. For example, some flash memory devices contain both slow and fast flash memory, but ReadyBoost can only use fast flash memory to speed up your computer.

  http://Windows.Microsoft.com/en-us/Windows/using-memory-storage-device-speed-computer#1TC=Windows-7

  Computers with discs hard fast (such as 7 200 or 10 000 rpm disks) could achieve minimum performance gains due to the already high disk i/o ReadyBoost. will read the files from the cache only when this so will improve performance. Hard drives surpass flash in sequential reading drives, but flash drives are faster when no sequential reads (because of the latency caused when the drive head must move to a different disk sector). As a result, ReadyBoost reads from the cache only for non sequential reads

• Using the ODP client result cache still shows it as running on AWR, is the work of cache?

  Hello

  I use the Oracle 12 manged customer ODP.net connected to a database of GR 11, 2. I recently went on the cache of results with great effectiveness.

  So, I thought I would try the result to the client cache. I have the setting turned on and restarted my db, but my questions always appear in the graphs of Enterprise manager and the AWR report. I would have thought if the query has been cached on the client, that it does not show.

  How will I know if it works or not?

  Thanks in advance.

  Adrian.

  Re-reading the original question, I missed the fact that you use managed ODP.NET. The client result cache does not support managed ODP.NET. Only unmanaged ODP.NET is because it uses the capacity, within the OIC, that uses the unmanaged code.

  I apologize for the misunderstanding.

• Update statement can be used depending on the result cache?

  Hi all

  I stumbled on an interesting question. UPDATE statement is used in the following function, even if the feature is created RESULT_CACHE. It seems illogical. I was wondering, is it possible?

  If so, why RESULT_CACHE is used?  Because it means "do not execute the function, look for the result of the hash table and return the results to the user ' if the UPDATE statement, so doesn't mean it should run for each call and use with RESULT_CACHE and UPDATE/DELETE/MERGE is illogical or wrong?

  Thanks for your help.

  Yes, it's the challenge of PL/SQL quiz - and the point of the quiz is only automatic relies on parsing by Oracle only supports arrays of account that is QUESTIONED.

  The tables that are affected by DML not a query as an update do not figure in automatic invalidation of a cache.

  I was hoping that the explanations given in the questionnaire itself would not lead to a thread - rather it would provide a pleasant and clear answer. So feel free to let me know if you think otherwise.

  As to why Oracle would let you include DML not a query inside a function of caching of result, well... I can easily accept that you shouldn't do this - in general. But I don't see that we should make it impossible. It would probably be a good candidate for an another PLW (PL/SQL warning), as in:

  "Non-requetes DML in a result caching function will not affect caching and can result in unexpected results."

• Using the Client result Cache

  Hi all

  I have a question about the use of the result of the client cache but first of all, here is the information on my database:

  SQL> SELECT * FROM v$version;

  TNS for Linux: Version 11.2.0.1.0 - Production
  NLSRTL Version 11.2.0.1.0 - Production
  
  

  I installed the Oracle Client Tools on my clientmachine. There a tnsnames.ora like this:

  ORCL =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = FEA11-119SRV)(PORT = 1521))
      )
      (CONNECT_DATA =
        (SERVICE_NAME = orcl.local)
      )
    )
  
  

  The result of the Client Cache is configured in the sqlnet.ora.

  ADR_BASE = /u01/app/oracle

  OCI_RESULT_CACHE_MAX_RSET_SIZE = 1024000
  NAMES.DIRECTORY_PATH = (EZCONNECT, TNSNAMES, HOSTNAME)
  
  

  The Databaseserver is configured like this:

  client_result_cache_size       1073741824
  client_result_cache_lag        3000
  
  

  After you set up a client's server, I try the SQL query on the clientmachine followign:

  sqlplus oracle/password@orcl
  
  set autotrace traceonly explain
  
  SELECT /*+ result_cache */ *
  FROM testtable;
  

  You cannot enable the customer with SQL result cache * more, no matter what you do with parameters. If you install the CD examples, you will find examples of code in cdemoqc.c and cdemoqc2.c that shows how with the OCI calls.

  You probably want to use the result of the server cache, there is a full demo of this here,

• Oracle result Cache problem

  Hello

  In our database, we have the following settings for caching the result:

  result_cache_max_result integer 5

  result_cache_max_size great whole 256256 K

  result_cache_mode chain MANUAL

  result_cache_remote_expiration integer 0

  But we use indicators no results hidden in questions, or tables that are enabled for result caching.

  So from my understanding, caching the result should not happen.

  But we met a performance problem, and when I checked the AWR report I found this:

  

  And also I found this activity latch:

  

  However, just set result_cache_max_size = 0 fixed to all our questions. Wait no more. Performance as expected.

  But how is that possible? I thought with result_cache_mode = manual and not using indicators of result cache or table modes,.

  There should be no result at all caching? Any max_size choose?

  Can someone help me understand what is happening here?

  Thank you and greet.

  The original poster was not to the point and they actually understand the docs.

  Sorry - I'm not okay. As I went to the docs are very EXPLICIT about how to disable the cache of result. If you turn it off, then it is enabled.

  The fact that they have tried to do is that when result_cache_mode is set to the default value of the MANUAL, because they showed, it is, while according to the docs 12 c only the results of queries that use the RESULT_CACHE indicator must be stored in the cache of result

  Maybe that's where you and OP have misunderstanding. on the RESULT_CACHE_MODE parameter and the parameter values. This seems to be a common misunderstanding.perhaps, because people are not read ALL the relevant articles of the RFSO and only looking at the section for this parameter.

  There is NOTHING in the doc of 12 c for this parameter that shows ANY correlation to determine whether the cache is enabled or not.

  Refer to the section "Setting the Mode of the result Cache"

  https://docs.Oracle.com/database/121/TGDBA/tune_result_cache.htm#CDEJCGJD

  As shown in table 15-3 there are ONLY two settings: MANUAL and FORCE. No adjustment said ANYTHING on toggle or if the cache is ENABLED or DISABLED.

  ... and they were not aware of all the queries that they had used this trick on.  When you're ready to values by default and don't use don't not result_cache indicator (as much), it's odd to find the cache of your result are so full.

  OK - the USER does not use the indicator result-cache to cache the results of the queries USERS. But if the cache is enabled (size not equal to zero) that according to the quote from the doc above has NO effect on the use of Oracle to cache for queries or non-deterministic function calls.

  I think a lot of people may be jumping on the server I mentioned first that article explicitly states that you must set the size to zero to disable hide and seek only to the section on setting the parameters.

  And that the "setting mode" section is confusing as it includes a paragraph that uses the expression "If you choose to activate the result cache.

  That subsection and the r-phrase likely cause people to think that the setting and the off/on State of the cache are one and the same.

  When the result cache is enabled, the database also highlights cache queries that call non-deterministic functions of PL/SQL. When caching SELECT statements that call functions, result cache dependencies of data for PL/SQL functions and titles of database objects. However, if the function uses the data that are not followed (such as sequences, SYSDATE , SYS_CONTEXT and package variables), uses the cache of result on queries that call this function can produce stale results. In this regard, the behavior of the cache of result is identical to the caching of PL/SQL functions. So always consider the accuracy of the data, as well as performance, if you choose to activate the result cache.

  But if all associated sections are interpreted in their context, it should clear up the misunderstanding.

  If you have a support contract, you can submit a request to have the documentation changed to update mode setting (table 15-3) article to explicitly declare the parameter mode does NOT determine if the cache is enabled or not.

• Sqlplus 10G result cache

  Hello
  We try to write an application to analyze the performance of our database.
  
  The problem now is that the sqlplus or the database is cached results.
  We use a 10g and 11g database
  
  Does anyone know how to do not cache the results
  
  Thank you * T

  N °

  The execution of a statement has three phases:

  parse
  run
  Fetch

  If a statement is presented for the first time, it will be analyzed and it will be in the shared pool.
  Oracle will determine a plan
  Subsequently, the statement is executed. If the data in the table are not in the cache buffers, Oracle will perform physical reads to get it into the buffer cache.

  Suppose for a moment, the same statement is executed once again
  Oracle will find the statement in the shared pool, so the statement that is not re-analyzed and no plan will be determined.
  Oracle will re - run the statement.
  If the data in the table are still in the buffer cache, Oracle just obtain data from the buffer cache.

  The buffer cache is currently limited in size, and your statement is not executed for awhile. Other statements are executed.
  Assume that your data will age to the buffer cache, but your statement is not age out of the shared pool.

  Then you must re - run the statement. It is not re-analysis, as it is still in the shared pool. Execution, Oracle will perform physical i/o again, in order to recover the data in the buffer cache.

  Now you re - run the statement, but this time your bind variables have different values. Oracle will only reassess the statement and determine a new explain plan (this is called a "child cursor")

  The situation you seem to want to force you will almost never have.
  In addition, usually the SQL you are running should not be 'random', so some time after you start the database, Oracle will not need to analyze all the time and will be able to obtain data from the buffer cache.

  Once that empty you the shared pool (all versions) or disable the buffer cache, Oracle will have to redo all integer.
  But it is a situation normally you won't and shouldn't need to have.

• Result Cache indicator

  Hi all
  What are the restrictions of use result indicator cache on queries? How to use Union or join or subqueries? What doc should I read about it?
  
  Also, I run the following queries on the HR diagram example:

  select first_name,(select /*+ RESULT_CACHE */ last_name from employees where employee_id=100) from employees;
  select first_name from (select /*+ RESULT_CACHE */ first_name from employees);

  Using

  select name, value from v$result_cache_statistics where id=7;

  I can check if the first subquery, where it is evaluated in each row, using no indicator result hides while the second use on. How do I?
  
  Best regards
  Val

  Select first_name, (select / * + RESULT_CACHE * / last_name of employees where employee_id = 100) of employees;

  (Of course, this is an artificial example, but one) result_cache indicator does not work in a scalar subquery, unless you move out in a CTE first (WITH clause) and b) without result caching, you will benefit from [url http://www.oratechinfo.co.uk/scalar_subqueries.html] scalar subquery caching anyway.

• Result Cache in oracle 11g release 2.0.2.0

  All,
  
  A few months ago I tried function result Cache 11 g version 2.0.1.0. The oracle of time mentioned that they have 3 ways to use this feature by setting the parameter result_cache_mode AUTOMATIC, MANUAL or FORCE. With AUTO (result_cache_mode = AUTO) mode you can identify the queries that can benefit from the cache of the result. I would like to know what views or function I see where he captures this information.
  In 11.2.0.1.0 documentation he was making reference to certain points of view (totally forgot the names of views) and said: those that will be available in 11.2.0.2.0.
  
  Did anyone know about this?
  
  Thanks in advance.

  user2486753 wrote:
  Although doc oracle didn't tell on AUTO it is still accepts this value and caches the result of the SQL query if you add / * + cache result * / allusion to the SQL.
  I know that they mentioned in 112010 somewhere that will help users find what SQL is good candidates for caching by running the app for a while. I couldn't just fine there.

  If we add AUTO and always passing the tip, this is the same behavior as MANUAL. I'm not sure I've seen the value of anywhere and neither its there in the docs too.

• ViewObject filtering (do not use ADFBC)

  ADF version: Update Oracle JDeveloper 11 g 2 (Build 5205) (11.1.1.0.2)
  
  I have an interesting problem. I have a table linked to a methodIterator through a dataControl. This table is filled with the data returned by a 3rd party Web Service, so we do not use ADFBC from here and there the methodIterator. I need programmaticly filter the rows in this table. I tried a ton of different approaches and have not found anything that works yet. Default filtering provided by the ADF for tables is not enough in my case, because it seems that all channels will be filtered by a clause of "begins by" and is also case sensitive. This behavior can be set at the level of the model layer because there is not ADFBC to do. I need finer control refined over the filter action. Just intercept the filter settings and by passing in a search on the web service method part 3 are not an option. This filtering should take place in memory. That's what I tried:
  
  DC DCBindingContainer = ADFUtils.getDCBindingContainer ();
  DCIteratorBinding iter = dc.findIteratorBinding("searchInboxIterator"); the methodIterator bound to my table
  ViewObject viewObject = iter.getViewObject ();
  ViewCriteria viewCriteria = viewObject.createViewCriteria ();
  Vcr1 ViewCriteriaRow = viewCriteria.createViewCriteriaRow ();
  VCR1.SetAttribute ("ep", "IS NULL");
  viewCriteria.add (vcr1);
  viewObject.applyViewCriteria (viewCriteria);
  viewObject.executeQuery ();
  
  He tries to filter all lines with the string "ep" attribute set to null. Unfortunately after having applied the criteria of display and the execution of the query, nothing seems to have filtered. I can loop through the rows of the view object after the execution of the query, and all lines are still present in the viewObject.
  
  Is what I'm trying to even possible without an ADFBC explicit tapes? If I'm on the right track, what Miss me?

  Hello

  If you do not use ADF BC can

  ViewObject viewObject = iter.getViewObject ();
  ViewCriteria viewCriteria = viewObject.createViewCriteria ();
  Vcr1 ViewCriteriaRow = viewCriteria.createViewCriteriaRow ();
  VCR1.SetAttribute ("ep", "IS NULL");
  viewCriteria.add (vcr1);
  viewObject.applyViewCriteria (viewCriteria);
  viewObject.executeQuery ();

  does not at all because you don't have picture objects or ViewCriteria.

  Filter the data in memory, you need to cache data in a managed bean (for example a table in the list) and build the table on that basis. Otherwise, to filter results WS, you call a method on the Web Service to obtain a filtered response (you can use the QueryListener on the table to do this)

• TimesTen and Oracle 11 g result cache

  Oracle 11g introduces the concept of cache the result whereby the result set of frequently executed queries are stored in the cache and used later when other users ask the same query. This is different from the caching of the data blocks and exceuting the query over and over again.
  
  Tom Kyte calls this materialized view just-in-time, in which case the results are dynamically evaluated without DBA intervention
  
  http://www.Oracle.com/technology/oramag/Oracle/07-Sep/o57asktom.html
  
  My point is that, given utilities like result_cache and possibility to use Solid State Disks in Oracle to accelerate physics I/O etc. is necessary for a product like TimesTen? It seems to me he could asdd just another layer of complexity?

  Oracle cache there result a useful tool, but it is significantly different from TimesTen. My understanding of the Oracle result cache is caching the results for rarely changing data such as search (currencies/identification code) tables, data reference that do not change often (list of counterparties) etc. It would be pointless to cache the result set when the data changes frequently.

  There is also another argument for the cache of SQL result that if you hit high on your CPU usage and that you have enough memory, then you can cache some defined thus results save on your cycles CPU.

  In view of the arguments on the wired RDBMS and drives (SSD), we can talk all day, but with SSDS does not eliminate the consideration for physical i/o optimizer. A table scan is a table scan if the data resides on disk SCSI or SSD. SSD will be faster, but we are still running physical IOs.

  What about TimesTen, the positioning of the product is different. TimesTen is closer to average than Oracle. It is designed to work closely at the application layer, while Oracle aims much more wide. There is no way one can replace TimesTen with any RDBMS wired for volumes of moderate and real-time response. Demand for the result cache has been around for a while. In areas like trading program and data on the market when the underlying data changes quickly, TimesTen will come handy, because time real/provisional data and calculations must be made almost in real time, with fewer complications of the execution engine. I don't see how we can deploy the result cache in this scenario. Due to underlying data change, Oracle is obliged to calculate queries almost everytime and the cache of result will be just wasted.

  Hope this helps,

  There is a problem with your installation of OS X. The easiest way, but not the fastest way to fix it is to reinstall the operating system. Unless you are in a hurry or have measured access to the network, it is what I suggest, especially since I don't know if there are any problems with the installation. Please backup all data before reinstalling. You won't need the backup unless something is wrong.

  The below, advanced shortcut if it works, can save you some downtime (and the cost of a download of several gigabyte, if necessary.)

  1 back up all data.

  2. disconnect all external storage devices.

  3. start in recovery mode. Select a language, if you are prompted. The OS X Utilities appears. One of the options is to install OS X. This is not what you do.

  4. This step is only necessary if you use FileVault 2. If you don't know what's FileVault, you use it. Go to the next step. Otherwise, launch utility disk, then select the icon for the volume FileVault ("Macintosh HD", unless you have given it a different name.) It will be nested under another icon of the disc. Select open in the file menu and enter your login password when you are prompted. Then quit disk utility must be returned to the main screen.

  5. Select get online help. Safari will launch. While in recovery, you will have no access to your Favorites, but you won't need them. Load this web page.

  6. triple - click anywhere in the line below to select this option:

  chflags -R norestricted /V*/*/S*/*/Caches

  Copy the selected text in the Clipboard by pressing Control-C key combination.

  7. Quit Safari. You go back to the OS X Utilities screen.

  In the menu bar, select

  Utilities ▹ Terminal

  Launch the Terminal application. Paste in the Terminal window by pressing the command-V key combination.

  Wait for a new line ending with a number sign (#) to appear. Quit the Terminal must be returned to the main screen.

  8. Select

  ▹ Restart 

  in the menu bar.

  9. This step must be performed after the restart, and while you are logged as administrator, not in recovery mode. If you have only one user account, you are the administrator.

  Select and copy this line as in step 6:

  sudo /usr/libexec/xpchelper --rebuild-cache

  Paste in a Terminal as before. You will be asked for your login password. Nothing displayed when you type. Type carefully, and then press return. If you do not have a password, you will need to configure one before you can run the command. You can get a warning to be careful. Confirm. You don't need to display the warning.

  If you see a message that your user name "is not in the sudoers file", then you have not logged as an administrator. Log in as one and repeat this step. You don't have to repeat the previous steps.

  Wait for a new line ending with a dollar sign ($) below what you entered.

  10. make as in step 9 with this line:

  sudo /usr/libexec/*/app_sandbox_cache_builder --rebuild-cache

  You can then quit Terminal.

• Zoom of Safari do not using full window

  Is anyone else seeing this... in the last 2-3 days that some sites (but not all) behave as expected or desired in Safari when I "zoom". Previous behavior (what I want) is for the entire page in the window of the browser to expand I have to zoom (and vice versa when I Zoom out).

  Instead, the page seems to be divided into images and content within each vertical frame performs a zoom, but not the width of the frame itself. The result is that the zoom will not use all of the available window width.

  Image #1 is the default zoom HuffPost.

  

  Image #2 is after I zoomed in a few levels.

  

  Notice how the text in the 'frame' (with white background) Center got a lot bigger, but it doesn't have the framework. Zoom does not use the full width available to the window as she always did before. Note that the links-spills bar now off the frame to the right. Clearly a problem of rendering here.

  Software conflict maybe?

  Oops.   I found my problem.

  There is a new item on the menu display of Safari... at least, I have never noticed before... called 'zoom text only '.  Somehow, which was fixed. Disabling this feature allowed to zoom to behave as you wish.

  I'll leave this message upward in the other case travels through it also.
