• Filtering and calculate the averages for subsets of a table

  I have a 2D picture that comes out of a loop, and I need to calculate the average of the subsets corresponding to iterations 0-9, 10-19, etc...  In addition, I need to filter the values above and below acceptable limits before calculating the average.  Any suggestions for how to address the issue?

  Here are examples of code does exactly that. This post, looks like you need an upper limit as well. I'll leave that as an exercise for you.

• IF database-> RAC database: estimate of the size of the SGA for each instance

  Hello!

  Let's say that there is a single instance with SGA 100 G size DB (assume this size is optimal for this database).

  If this database is intended to be converted to a RAC database with 2 instances (suppose DB workload will be spread over multiple instances).

  How to estimate the needs of SGA size for each instance in the RAC database?

  It takes 50G + General cool CARS (say 15%) for each instance?

  (Do not consider situation when one of the instances has failed, and all the charge redirects to an instance having survived)

  I'd be grateful if someone has offered or provided useful references.

  As a general rule, I would size the SGA on new nodes to 120% of the SGA to single instance. Yes, this means that you will more than double the size of the SGA. You will need additional space to hold the load memory Cache Fusion. And the buffer Cache are possibly a little more space to store additional versions of blocks that seem to accompany the many implementations of CARS. Now, it's just a rule of thumb, so it has a high degree to be very wrong.

  You'll want to consider two big things... (1) the service being used. Will you take advantage of the services to perform the partitioning application? If so, instances can see various workloads that can lead to requests for different resources. (2) you will support a kind of failover (TAF or manual failover) applications? If so, then the LMS must be sufficiently sized to support the additional workload.

  See you soon,.

• How to calculate the deduction for Initial depreciation for assets?

  Hello
  
  I am trying to set up books FA tax to calculate the initial allowance (depreciation) active @ 10% regardless of the date of commissioning.
  
  For example. Year Jan - Dec. -rated Convention's same month. If an asset is added in Dec-2010, it should still depreciate 10% instead of 0.8333333333333333

• Is there a way to dynamically calculate the values for the IN operator?

  I want to know if there is a way to dynamically calculate the criteria to include within an IN operator in the WHERE clause. "For example when I try to run the following I get an Oracle error message ' OR!-01722: invalid number." The script below is just an example to help illistrate the problem, I don't want to hardcode the values assigned to the v_test directly within the IN operator because the values of v_test will change from user to user.
  
  DECLARE
  
  v_test VARCHAR2 (10): = '1,15,25,55';
  v_tmp VARCHAR2 (50): = NULL;
  
  BEGIN
  SELECT d.metric_title IN the tbl_health_metric_definition v_tmp d
  WHERE d.metric_status = 'Active' AND d.metric_id IN (v_test);
  END;

  You can convert the string "1,15,25,55" online like this

  SQL> select regexp_substr('1,15,25,55' ,'[^,]+', 1, level) list
    2    from dual
    3  connect by level <= NVL( LENGTH( REGEXP_REPLACE( '1,15,25,55' , '[^,]+', NULL ) ), 0 ) + 1
    4  /
  
  LIST
  ----------
  1
  15
  25
  55
  

  and use this selection in your IN clause.

• How to calculate the width for assets

  Hello

  I want to have a large image that covers the entire width of a device.

  How can I calculate which corresponds to the width I want?

  I'll probably have 3 versions, each for one of the 3 DPI settings.

  Thank you.

  A desktop application is very different from a mobile application.  On the desktop, you usually have a threshold of width/height that you know that each monitor will be at least in bulk, for example 800 x 600.  Some people design applications for just this minimum resolution and some people create applications that can grow bigger than, but in the end you basically the exact same application on each monitor.

  The story is very different on mobile devices.  The range of screen size and screen DPIS is much more important and should be taken into account.  You have cell phones that are often something like 480 x 800 in portrait orientation, but then also 800 x 480 in landscape orientation.  If you really can't design an app that can be only 480 x 480 because it's just not lots of space and all devices will have a ton of valuable space that is not used.

  Then put in the form of tablets, which usually have a screen size much more important for the provision of application you have a mobile phone often is not make sense on a tablet.  Many applications have a completely different user interface on tablet vs on the phone.

  So in the mobile applications you will want to use relative sizing and positioning as much as possible (width/height=100%, top, left, right, down, VerticalLayout/HorizontalLayout, etc.), you'll want to learn more about the options you have available in the Flex SDK kit to treat the different PPP (dpi scaling and CSS media questions), and you also need to think if your application needs to act even on shelves as on mobile phones or if the interface User should be completely different.

• Aggregator customized to calculate the standard deviation

  Hello
  This is probably already available or easy to implement, but I find it difficult to find samples for writing a custom aggregation and ParallelAwareAggregator.
  
  I'm figuring the difference type of a variable in my item being cached in a real-time system. I want to aggregate the result sum [(X-X') ^ 2] where I spend X' (average) of the client. Can someone help me with an example?
  
  Thank you
  Sairam

  Hi Sairam,

  in fact, you probably have better use the single-pass approach to calculate the standard deviation, as the average of the values may change before you calculate the number of entries and the average gap.

  You can use the following formula to calculate the standard deviation in one pass: sqrt (N * sum (sqr (Xi)) - sqr (sum (Xi))) / N, where the sqr function is the square of a value, the square root function is the square root of the value, N is the number of entries and Xi is the value to calculate the gap type from the entry of the i - th.

  You can do something like this:

  public static class StdDeviation implements ParallelAwareAggregator {
  
    public static class PartialResult implements Serializable {
  
        private long numberOfElements;
        private BigDecimal sum;
        private BigDecimal sumSquare;
  
        public PartialResult(long numberOfElements, BigDecimal sum, BigDecimal sumSquare) {
            this.numberOfElements = numberOfElements;
            this.sum = sum;
            this.sumSquare = sumSquare;
        }
    }
  
    public static class ParallelPart extends StdDeviation implements EntryAggregator {
  
       private ParallelPart(ValueExtractor extractor) {
          super(extractor);
       }
    }
  
    private ValueExtractor extractor;
  
    private transient boolean notParallel;
  
    public StdDeviation(ValueExtractor extractor) {
      this.extractor = extractor;
      this.notParallel = true;
    }
  
    public Object aggregate(Set entries) {
       ValueExtractor extractor = this.extractor;
       BigDecimal sum = 0;
       BigDecimal sumSquare = 0;
       long num = 0;
       for (InvocableMap.Entry entry : (Set) partialResults) {
          sum = sum.add(partialResult.sum);
          sumSquare = sumSquare.add(partialResult.sumSquare);
          num += partialResult.numberOfElements;
       }
  
       return calculateStdDeviation(num, sum, sumSquare);
    }
  
    public EntryAggregator getParallelAggregator() {
  
       // you could return this, instead of ParallelPart
       //
       // return this;
  
       return new ParallelPart(extractor);
    }
  
    private static Number calculateStdDeviation(long num, BigDecimal sum, BigDecimal sumSquare) {
       BigDecimal partRes = sumSquare.multiply(new BigDecimal(num)).subtract(sum.multiply(sum));
  
       // you can replace the square rooting of a double value with a proper implementation of square root for BigDecimals,
       // which I omitted for the sake of brevity, and then you can do BigDecimal division (make sure you provide a MathContext)
       return Math.sqrt(partRes.doubleValue())/num;
    }
  
    public static Number execute(NamedCache cache, ValueExtractor extractor) {
       return (Number) cache.aggregateAll(AlwaysFilter.INSTANCE, new StdDeviation(extractor));
    }
  }
  

  There is actually no reason for the class ParallelPart to exist. I put it here to illustrate that there can be a different aggregator instance to the ParallelAware aggregator optimized to run on the side of the storage, but you could just "this" return of the getParallelAggregator() method, it wouldn't make a difference for this implementation of the aggregator.

  You can replace the rooting square a double value with a good implementation of the square root of BigDecimals, which I omitted for brevity, and then you can make division BigDecimal (make sure that you provide a MathContext)

  I also omitted the ExternalizableLite and PortableObject implementations (and necessary parameterless constructors) for brevity of the ParallelPart and PartialResult classes.

  In addition, you may need some mojo if you want to use a PofExtractor instead of a regular Value Extractor to avoid the deserialization of the cached value.

  You can perform the aggregation with the execute method, passing the cache altogether on the Extractor which extracts the value as a BigDecimal value cached.

  Best regards

  Hi guys,.
  
  It's a situation where I have to produce a few new lines with projections based on Q4 RETAIL_SALES_AMT
  RETAIL_SALES_AMOUNT and fourth ' rs following WHOLESALE_AMT. As you can see from the sample data for a specific customer,
  product I have populated only until 01/04/2006 retail_sales_amt but WHOLE_SALE amt for the same product and customer
  are there up to 01/04/2007.
  
  I have to produce a PROJECTED RETAIL_SALES_AMT and it must be inserted in a new line with an indicator to identify
  a proposed line. Here, in this case I have to produce a new line of projection from 07/01/2006,10/01/2006 and 01/01/2007
  the RETAIL_SALES_AMT. The method of calculation is provided for in:
  
  retail_sales_amt scheduled for 07/01/2006=.345+ ((01/07/2006 whole_sales-01/04/2006 whole_sales) / (01/04/2006 whole_sale)))
  * 01/04/2006 RETAIL_SALES_AMT and move forward to subsequent quarters.
  
  Is it possible that I can use a query to produce these new lines by calculating the RETAIL_SALES_AMT on the fly, or any other
  How to procedure.
  
  Please help as it seems a little complicated.

       FROM     table_x
  --     WHERE     ...     -- Any filtering goes here
  )
  ,     tree     AS
  (
       SELECT     got_prev.*
       ,     SYS_CONNECT_BY_PATH ( CASE
                             WHEN  LEVEL = 1
                             THEN  retail_sales_amt
                             ELSE  ( .345
                                            + wholesale_amt
                                            - prev_wholesale_amt
                                ) / prev_wholesale_amt
                            END
                          , '*'
                          )                    AS path
       FROM     got_prev
       START WITH     retail_sales_amt     IS NOT NULL
       CONNECT BY     retail_sales_amt     IS NULL
            AND     quarter               = ADD_MONTHS (PRIOR quarter, 3)
            AND     customer          = PRIOR customer
            AND     product               = PRIOR product
  )
  SELECT       quarter
  ,       customer
  ,       product
  ,       COALESCE ( retail_sales_amt
               , eval_number ( LTRIM ( path
                                         , '*'
                             )       )
               )      AS retail_sales_amt

  FROM       tree
  ORDER BY  customer
  ,            product
  ,       quarter
  ;
  

  I posted earlier the eval_number function.

  In this query, a group of consecutive quarters, where the first group a retail_sales_num and the rest of the members of the group are not, is treated as a hierarchy. The retail_sales_amt of all members (except the first) will be based on the previous, as well as the wholesale_amts past and present.
  Say that a tree is 5 points of time (as in your examples of data). We can calculate the 2nd point in several ways: using analytical functions, for example. But we cannot use the same formula to calculate the 3rd point, because the calculation of section 2 must be completed before we can calculate the 3rd. It goes the same for the 4th and 5th.
  This is CONNECT BY arrives. CONNECT BY is one thing in Oracle SQL that can be recursively; children may find themselves once their parents are found, in the same way we want to calculate the nth retail_sales_amt once the amount of the n-minus-1 has been calculated. To do this, we use SYS_CONNECT_BY_PATH, where the first element in the path is the retail_sales_amt given, and all others are the factor to multiply this number to get the next amount.
  SYS_CONNECT_BY_PATH produces a string like ' * 324562 *. 4965935 *-. 0057739', which should be interpreted as a number. TO_NUMBER won't: TO_NUMBER cannot convert only a single numeric literal. Instead, we have a function defined by the user who put this string dynamically in the SELECT clause of a query, where it is interpreted as a numeric expression.
