increase the 'size of the cache pending' of our cube ASO to capture whole database in memory?

Happy new year everyone,

We want to take full advantage of our 54 GB of free memory on our server Exalytics X 4.

From this site, I read more in anticipation of the ASO cache size will reduce the disk i/o.

The default / .dat file size of data from our database of the ASO is 9.9 GB with more 100 million cells entry level.

We should increase the 'size of the cache in waiting"our ASO to 9.9 GB cube so that the entire .dat will be cached?

Thank you.

===============

PS. Here's what I found in ASO Tuning white paper, which seems to recommend 512 MB or 1 GB.

ASO cache size has an effect on the performance of loading data. For

small databases with cells of entry 2 million or less, the default

ASO cache size to 32 MB is sufficient. For a larger database

with 20 million cells, 64 or 128 MB of cache is more appropriate.

A database with 1 billion cells or more, the size of the cache can

be placed as high as 512 MB or 1 GB if memory permits.

Put all of the memory base looks really cool, but my experience is that in most cases it is not necessary. In my experience, the benefit of the ASO cache decreases rapidly. Here's an example I wrote about running aggregations:

    Yes, increase the cache data and make sure you stop/start the database after making changes, to be honest, I think it's down to tests to find the optimum size.

  • Withdrawal of the cache folder ready to call APEX earphone with GlassFish

    Hello

    We had several unexplained crashes of APEX in our environment in recent months. All this happened after we moved to GlassFish the listener to the APEX. The symptoms were always that all connections in the JDBC connection pool have been used and we had to restart the instance of GlassFish server to free up.

    I finally managed to replicate and to determine the cause of this recurring problem. The culprit is file caching used by the auditor of the APEX to the cache file. We use it to cache the downloads of image of the database with a procedure, and the caching folder was set to/tmp/apex/cache. I believe that this is the default setting. All right, when the procedure was called the images were downloaded from the database and caching under/tmp/apex/cache. However, for some (still unexplained) reason, Linux sometimes removes this system of files/tmp folder. This seems to happen at any time after a period of inactivity. We have not to restart the server. After that the file is missing, the listener of the APEX is unable to recreate it, continues to create new database connections until the configured maximum value is reached, and we need to restart the instance of GlassFish to free up. It also recreates the cache folder.

    Our environment: GlassFish 3.1.1 and 3.1.2, APEX listener 1.1.3 Oracle Linux 6.2. I didn't try the new listener APEX 1.1.4 yet I'm not sure if this problem has been fixed in the latest version.

    (kind of reminds me of the problem where the APEX configuration file is by default submitted/tmp and also disappears from time to time)

    Hello Matthias.

    (kind of reminds me of the problem where the APEX configuration file is by default submitted/tmp and also disappears from time to time)

    This is exactly the same cause. Why don't you set up APEX listener to use a permanent seat for his repertoire of setting cached when you set the config.dir ? The corresponding setting in the apex - config.xml is named apex.cache.directory and must be paid when caching is enabled.
    Of course, it would be useful APEX auditor would report an error when its cache dir is missing rather than die in silence. It would be better to change the mode of caching mode not cached when these errors occur. Maybe it will be better in a future release.

  • How to increase the SGA

    Hi all

    Oracle 9i

    We have a database of PROD that has the performance issue.
    Our Production Linux server has 12G of physical memory.
    My boss told me 6G memory allocation to the database.

    I therefore change our init.ora and set TARGET_SGA = 6G

    But when I restart our database and the SGA VIEW, it shows only 700 MB.
    What are the parameters in init.ora I should increase to give me 6G SHOW what CMS?


    Thank you very much.

    SGA_MAX_SIZE large integer 715724556

    You can more than double existing value.

    Realize that 2 GB is the largest positive integer that can be represented in 32 - bit; That is why the max 1.7 GB on SGA.
    Oracle had to book the little extra space for non - SGA memory resident data structures.

  • Size of data Cache is full

    Dear,

    I am facing a problem with the data cache. I increased the data cache. but it seems that there's something wrong with my business rule. In accordance with the following:


    If you keep increasing the cache, but you still have this issue, it's time for you to think about your business rule or your design. Because more memory you allocate for the data cache, the more essbase RAM will succeed permanently (never released even the rule has already finished) unless you restart the app/Essbase cube

    My question : is there away to restart the app/Essbase cube without restarting the Essbase Server?  It makes no sense that whenever I have test the business rule, I need to do a reboot of the essbase server, if it does not work properly.

    Thank you in advance!

  • Dynamics Processor Calc does not reach more than [100] ESM blocks during the calculation, please increase the CalcLockBlock setting, and then try again (a small data cache setting can also cause this problem, check the size of data cache setting).

    Hello

    Our environment is Essbase 11.1.2.2 and work on Essbase EAS and components of Shared Services. One of our user tried to execute the Script of Cal of a single application and in the face of this error.

    Dynamics Processor Calc does not reach more than [100] ESM blocks during the calculation, please increase the CalcLockBlock setting, and then try again (a small data cache setting can also cause this problem, check the size of data cache setting).


    I did a few Google and found that we need to add something in the Essbase.cfg file as below.

    Dynamics Processor Calc 1012704 fails to more blocks ESM number for the calculation, please increase the CalcLockBlock setting, and then try again (a small data cache setting can also cause this problem, check the size of data cache setting).

    Possible problems

    Analytical services cannot lock enough blocks to perform the calculation.

    Possible solutions

    Increase the number of blocks of analytical Services can allocate to a calculation:

    1. Set the maximum number of blocks of analytical Services can allocate at least 500.
      1. If you are not a $ARBORPATH/bin/essbase.cfg on the file server computer, create one using a text editor.
      2. In the essbase.cfg folder on the server computer, set CALCLOCKBLOCKHIGH to 500.
      3. Stopping and restarting Analysis server.
    2. Add the command SET LOCKBLOCK STUDENT at the beginning of the calculation script.
    3. Set the cache of data large enough to hold all the blocks specified in the CALCLOCKBLOCKHIGH parameter.

    In fact in our queue (essbase.cfg) Config Server we have given below added.

    CalcLockBlockHigh 2000

    CalcLockBlockDefault 200

    CalcLockBlocklow 50


    So my question is if edit us the file Essbase.cfg and add the above settings restart services will work?  and if yes, why should change us the configuration file of server if the problem concerns a Cal Script application. Please guide me how to do this.

  • Set the size of the cache does not work (to the great usefulness of RAM)

    Hello
    I posted this question in another forum, but they told me it would be better to aks that here:
    I m read in a csv table and put in a primary database (DB_QUEUE)
    and several secondary databases (DB_BTREE). I m using the Berkeley DB 4.7
    for with C++. For the primary database, I let the standart for the secondary cache size
    databases that I want to use 16 MB:

    unsigned long cache_byte = (1024 * 1024 * 16);
    s [a]-> set_cachesize(0,cache_byte,1)

    dry [*] are the secondary databases
    and the size of the cache is set before you open databases.
    The problem is when I run the program it allocates more memory.
    but it should just use a little bit more than once 16 MB.
    Can someone help me?

    You can open all databases in a unique environment, with just a cache? Happens usually better, because Berkeley DB can share the cache based on access patterns.

    That said, an increase in size of the memory can be caused by a leak of any where in the application - it may have nothing to do with the cache of Berkeley DB. Have all of the tools that could help track where the memory is allocated? If you're on Linux, valgrind (http://valgrind.org) is great for this sort of thing.

    Kind regards

  • Is it possible to increase the font size on web pages? I can increase the size of the page but then lose the ability to see the entire page.

    I've just updated El Capitan, but the font size on web pages went all teeny weeny.

    I was wondering if we could increase the font size? The page can expand via "zoom in", but then lose the ability to view the web page in the blink of an eye.

    Yes.  Open the Terminal app and type the following command followed by the Enter key or return:

    : write com.apple.Safari com.apple.Safari.ContentPageGroupIdentifier.WebKit2MinimumFontSize - int XX

    (triple click on the line to select it to copy and paste into the Terminal application).

    Change the XX to the font size you want as the minimum font by default.

    Or you can use a css style sheet.  This site describes it and the Terminal method: specify Minimum font size in Safari 10.0, macOS Sierra
