Cached data?

I'm confused with shared application Module, it says to put the view object querys cache data, but entity object do the same? so which is better for a refreshable data cache do?


Also if I want to create an entity not simple db view object, is not possible to create a key primary rowId... so is better to use module app shared, in this case bc entity is not possible to create?


I want to cache data bc I need improve performance...

A simple explanation is that shared AM(Session/Application level) can help you to share the result of the query (Collection of lines wrapping your EO instances), while the feature Cache cache instances of entity used my multiple ViewObjects for a specific transaction. More details here - http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/bclookups.htm. AM shared makes sense if you want to cache the business metadata (master data such as country codes, currencies, etc.) who can not change frequently.

  • Federated back cached data are saved to disk on the local cluster?

    With the new feature Federated consistent caching, 12.2.x, is the internal cache containing rear replication data saved to the local drive?

    What happens if the local cluster goes down, when there is great in waiting for data of backlog waiting to be replicated (probably due to remote cluster being down for an extended period)

    Can this back then recovered and reread cluster remote automatically when we have cold restart the local cluster?

    Any pointers to documentation of coherence on the above issues would be useful.

    To persist a Federated Cache, including arrears, all you need to do is configure on your diagram of federated, as you would for a distributed system.

    Why?  Federated Caches are in fact increased distributed Caches, which basically means that all of the features available for distributed Caches are also available to Federated Caches!

    Basically just add the following to your Federated plan

    active by default

    For more information on the new features of persistence, take a look at:

  • The question of performance - cached data from a large table

    Hi all

    I have a general question about caching, I use an Oracle 11 g R2 server.

    I have a large table on 50 million lines, which is very often consulted by my application. Some query runs slowly and some are ok. But (of course) when the data in the table is already in the cache (so basically when a user asks the same thing twice or several times) it works very quickly.

    Does anyone have any recommendations on the caching of data / table of this size?

    Thank you very much.

    Your user name has run a query to return the lines 68 000 - what type of user is, a human being cannot cope eventually with that a lot of data and it's not entirely surprising that he might take a long time to return.

    One thing I would check is if you still get the same execution plan - Oracle here estimates are out by a factor of about 95 (7 100 vs 68 500 returned planned lines) may be a part of your change in the calendar refers to plan changes.

    If you check the numbers you will see about half your time came to survey the unique index, and half visited the table. In general, it is hard to beat Oracle to cache algorithms, but the indexes are often much smaller than the paintings they cover, so it is possible that your best strategy is to protect this index at the expense of the table. Rather than trying to create a cache to KEEP the index, however, you MIGHT find that you get some advantage to create a cache of RECYCLING for the table, using a small percentage of available memory - the goal is to arrange things so that the table blocks that you revisit do not grow the index blocks that you will come back to memory.

    Another detail to consider is that if you visit the index and the table completely random (for 68 500 sites), it is possible that you find yourself re-reading blocks several times during the visit. If you order the intermediate result set of driving all table first you find you're walk the index and the table in the order and that you don't have to reread all the blocks. It's something that only you can know, however.  The code will have to change to include a view of inline with a dash of no_merge and no_eliminate_oby.

    You don't need a "cache of 3rd party" mechanism. Simply save the images in memory (you know, like a variable)? and to recover from memory instead of the network when you need.

  • NOT for Windows implements cache data from previous call.

    Hi all, I am facing a very strange problem. I wrote a native extenion in C++. This extension wrapps another class C++ that performs a mathematical operation. The extension itself

    Gets the vectors of std of result of that class Math and I convert them to vector AS3. < vector < Vector3D > > 2 dimension vector, and then back to Flash.

    The problem is that the first call the vector returned contains the correct data.

    But on the next call (just after the first) when passing a new data for the extension return another set of news given what is happening she return a vector with both old and new data.

    Inside the DLL I clean everything including vectors and releasing all the pointer. Still nothing helps. It's as if the DLL keeps old data inside itself.

    Any help will be greatly appreciated!

    Make sure that in the source of the C++ DLL you wrap all methods Callable Wrapper API DO with extern "C". __declspec(dllexport) is not enough.

  • Cached data sources

    I am running CF 7.02 and I see odd behavior in the following circumstances...
    I have 2 SQL Server databases (Widget and Widget_dev)

    I have 1 set datasource (widget)

    In certain circumstances, I change the DB that points to the data source at widget_dev. Most of the CF code has 'widget' hard-coded.

    The problem is that CF always behaves as if I'm talking to the database complete 'widget '.

    I tried the deselection of the 'conservation of connections' under Advanced settings and restart all CF services, but to no avail.

    If I create a source data "widget-dev' that points to the database"widget-dev' and then change the data source for the page of the CF, it works...

    Any ideas how I can deal with this problem?
    Thank you

    Is there a schema and data in the cube?

  • Data cache

    Hello

    When I go to the Properties tab on the Essbase database, I found the settings of the cache as follows:

    The Cache setting index: 300000

    Framework Cache data: 300000

    Is this value in MB? This value 300 MB or KB?

    Essbase allocates the memory for the process of ESSRVR.exe based on the user load. On a freshly restarted system or if you start/stop Essbase used memory is the minimum amount of memory it will use. If you examine the database statistics in environmental assessments, you will see the file index/caches use 0 out of the maximum amount of memory.

    Once the system has been used by users the maximum amount of memory will grow toward what would be the upper limit.

    So the quick answer is the default amount of memory when an Essbase database starts is really driven out of the size of the first contour which is usually quite a bit less when users start using all the various caches will begin to approach their maximum sizes.

  • Data buffers Cache vs. data Retreival

    Hello all-

    I want to know how the increase / decrease in the effects of data cache, the size of the size of the buffer for data retreival?

    I was going through the SER60 and he said:

    * "When you retrieve data in the Essbase Add-in for Excel worksheet or use the report generator to retrieve data, Essbase uses the extraction buffer to optimize recovery" * "

    There is an interdependence between cache data and memory data retreival buffer size?

    Also in SER60 I found in the section "activating dynamic recovery buffer Sizing" as follows:

    If a block of very large database and recoveries include a large percentage of cells in each block through several blocks, consider setting the option VLBREPORT in the essbase.cfg of Essbase configuration file.

    Someone at - he used this command in the past and can made me know the advantages and disadvantages of it?

    Thank you!

    Important notes around the use of VLBREPORT

    The parameter does not apply to databases of global storage.
    The VLBREPORT configuration setting applies only to databases that contain no members dynamic Calc, attribute or dynamic time series.

    Also the buffer cache and the recovery of the buffer are completely separated, because as far as I know

    See you soon

  • Data file Cache Vs I/O buffer

    Hello all-

    I lived chapter of parameters for the Ser60 cache and I have found that if my storage type is file cache settings buffered IO data is not used.

    I have a database that is buffering of i/o & RLE encoding and have the following cache settings:

    File data cache: 300000 (KB)
    Data cache: 37500 (KB)

    Can someone let me know if this database would be to use cache data files?

    If I decrease the cache of data files and increase the data cache would it effect application performance

    Thank you!

    If you look at the tab caches, you will see that none of your data files cache is used. in order to do no amtter what this number is.

    The cache setting affects how many blocks (uncompressed) that can enter the memory, so the encoding type has no effect on it, do not look at what data cache hit ratio in the statistics tab. If you get a low hit ratio, while you would like to consider to increase it. In addition, if you have a lot of dynamic calculations on the dense dimensions you want to increase as well.

  • Recover cache or server: what is logical to Firefox

    I clicked on a hypertext link to visit a web site that I had not visited for a few months. Firefox showed me the page as it was on my last visit there.
    I pressed F5 and the page was updated to the latest version.
    I don't seem to have this problem with other sites; just this one.
    Someone understands the Firefox logic uses to determine whether to display a page in the cache, or get the last page of the web server?

    Using Firefox 10; Windows XP

    The site cannot send an ETag header in the response headers or otherwise send info that makes Firefox think the cached data expired.

  • Caching server and IPv6 support

    Anyone know if it is possible to configure the server for caching to work if you are using a dual stack IPv4 and IPv6 network.

    When running dua-stack all client devices will prefer IPv6 when it is possible so set cache server service from Apple is to see every customer who logs as coming from a separate network rather than a single network. It doesn't seem to be a way to configure the server caching on OS X Server 5 for an IPv6 subnet, it accepts IPv4 addresses.

    Before that I have to submit this as a bug can someone prove me wrong with a workaround to get a double network stack to work with caching server.

    I got this job, it was just a matter of editing the configuration file server caching by hand to add the IPv6 range.

    The configuration file is located in /Library/Server/Caching/Config/Config.plist

    Make sure that the caching server does not work as you change the configuration file.

    Open the file in the Terminal for editing and search for the following text:

    < key > PreviousDataPaths < / key >

    < table >

    < string > / library/server/cache/data < / string >

    < / array >

    < key > region < / key >

    < string > 65622637284725D55356E27799AC1535 < / string >

    I will use the example of a range of IPv6 for the following subnet, 2001:377:3f:65ec: / 64

    Change the configuration file to add the IPv6 range as follows:

    < key > PreviousDataPaths < / key >

    < table >

    < string > / library/server/cache/data < / string >

    < / array >

    < key > PublicRanges < / key >

    < table >

    < dict >

    < key > first < / keys >

    < string > 2001:377:3f:65ec:0:0:0:0 < / string >

    < key > last < / key >

    < string > 2001:377:3f:65ec:ffff:ffff:ffff:ffff < / string >

    < / dict >

    < / array >

    < key > region < / key >

    < string > 65622637284725D55356E27799AC1535 < / string >

    Now add the TXT DNS record in the zone file located in /Library/Server/named/db.example.com

    _aaplcache._tcp 259200 IN TXT "prs = 2001:377:3f:65ec:0:0:0:0 - 2001:377:3f:65ec:ffff:ffff:ffff:ffff.

    Now start the update server cache and restart the DNS server if it is running.

  • Is there a way to get a list of all applications / updates that are cached on your server?

    Is there a way to get a list of all applications / updates that are cached on your server?  Of course, we see the space that contains each category.  But I would like a detailed list of the individual items that are actually cached.

    ITD be even better if I could get a scoreboard that showed me how many times a particular point was served to customers.

    Yes.  But you need a little magic Terminal to get the desired data.  Caching server is managed by a sqlite database.  To examine the contents, follow these basic steps:

    1: connect to the database using the following command:

    sudo sqlite3 /Library/Server/Caching/Data/AssetInfo.db

    2: to structure the data, run these two commands to the sqlite command-line prompt:

    .blog column

    . Headers on

    3: to find everything that is stored, run this command (you'll get iCloud cached documents, books, iOS apps, etc.):

    Select * from ZASSET;

    4: to narrow the results down to elements called by software updates, try this:

    Select * from ZASSET where ZURI as "content %";

    You could get a line that looks similar to the following:

    403 2 6 0 2012986793 474949928.477396 476912032.644505 e03448847909547fb8c7d4ecd5a7b6dd FAB32A72-DE33-469D-A7DF-3CE1A1F9A4D2 on Wednesday, August 5, 2015 18:00:30 GMT

    / Content/downloads/42/44/031-30888/bhrkylcnycxmtug9daw3g4magqb7dl7hba/OSXUpdComb o10.1

    (added the newline for readability)

    It is an OS X Combo update.  It is located on the drive to library/server/cache/Data/FAB32A72-DE33-469D-A7DF-3CE1A1F9A4D2 / the file is probably named 0, but if you want to use it, just add at the end of the .pkg file.

    I hope this helps.  Put server cache saves a lot of data.

    Oh, to quit the sqlite command line tool, simply type .quit and press return.
