• analyze the table & dbms_stats (chained lines)

  Hi guys,.
  
  Understand that dbms_stats collect statistics on (chained rows).
  To get chained lines, we can use one of the below:
  1. analyze the < table_name > table list chained rows;
  2 analyze the table < table_name > statistical calculation;
  
  the first lists the information chained rows in the CHAINED_ROWS table.
  the 2nd is best so that the information of chain_cnt are fulfilled in dba_tables. I can easily get the percentage of channel count by diviiding with the num_rows (for example if you need to list tables with 10 > string cnt percentage it would be easy).
  
  Right now, I'm leaving the need to collect statistics for night work by default oracle (who gather for table with variation in percentage of stale or > 10)... However, come together to string cnts.
  Can advise how can I get the string cnt without risking my existing services?
  
  And also will analyze statistics of table < table_name > estimate; replace my existing histograms?
  
  Thank you

• Analyze the table of variants

  I have a request, where we read binary data by Ethernet to high speed (~ 500 Hz). This data consists of hundreds of measures and other variables of all types (floats, integers, strings, etc.). I already have the code to analyze these data and store it in an array of variant.

  Now, I would like to take this array of variant and map each element to a particular variable.

  Because the data is stored in a predefined sequence (element #1 = speed, element #2 = power, element #3 =...), I considered looping through the array of varying and using a structure dealing with a case for each index of the array (see attachment). However, it is very heavy because the case structure has hundreds of cases (one for each element of the array) and it is impossible to insert a new item in the structure of business without dialing manually anyway.

  Can someone point me to a simpler implementation? If I was using C, I'd probably memcpy binary data directly in a structure aligned bytes. Is there any equivalent in LabVIEW, you use clusters?

  (Note: using LabVIEW 2014)

  Very well.  I thought about such a VI came out probably somewhere in vi.lib.

  However, I have also been concerned about the case where the table of variants isn't an different LabVIEW application.  In this case, I don't expect that the name and information of TypeDef would be in the variants, as specific to LabVIEW, so I was thinking something like this:

  Degree: Degree of parallelism. The default for the level is set to NULL. The default value can be changed using the SET_PARAM procedure. NULL means use the default value of the table specified by the LEVEL clause in the CREATE TABLE or ALTER TABLE statement. Use the constant DBMS_STATS. DEFAULT_DEGREE to specify the default value based on the initialization parameters. The AUTO_DEGREE value determines the degree of parallelism automatically. It's 1 (series performance) or DEFAULT_DEGREE (the default value of the system will depend on the number of processors and initialization parameters) according to the size of the object

• How can I search and return several items from the table quickly (like Matlab find)?

  Hi, I'm a pretty experienced Labview programmer, and I've always wondered if there is a way to quickly search for pictures on several items that meet the selection criteria, equivalent to the Matlab find command.  While my inability to do in Labview has always annoyed me, I now have an application that requires this capability and I need to find a solution.

  Is the fastest way I've found to do this in labview to perform comparisons on the data vectors, then use the Boolean value that results from vector to analyze the table using a loop and shift registers.  I enclose an extract vi a analysis comparative vi to one of the simple searches that I need to do.  On my laptop, this research takes about 600 ms.  In comparison, the equivalent in Matlab:

  newArray=oldArray(find(oldArray(:,4)./oldArray(:,2)>1.5),;

  runs in about 1.2ms.  So, the way I am doing this in Labview is only 400 times slower

  Needless to say, I need to make these types of research many times, and these additional 599 ms start to add up pretty quickly!

  Thanks for your help,

  Aaron

  Hi Aaron,

  the slow part is probably "build group" of the node in the loop.

  Try this:

  Define an array the same size as the input data (or simply uses a copy of it) and the wire that to the shift register. Keep a counter of lines found in the loop. Use IndexArray and ReplaceArraySubset for the loop to move rows found at the beginning of the table (overwrite the 'bad' lines). After the loop simply ReshapeArray the number of found lines...

  The "ANALYZE" command is obsolete and to be used only for specific purposes (for example, the keyword VALIDATE or to count the number of chained rows).

  The DBMS_STATS package with its set of procedures replaces that command. These procedures, as well as the automated job/tasks already configured in 10 g and 11 g, should be used to collect optimizer statistics. Essentially of statistics on the nature of the data that is present. The SQL optimizer then uses these statistics to determine an execution plan to retrieve the data requested by the user/application.

  Do not use this command to analyze the tables so you need to use DBMS_STATS. Procedure GATHER_TABLE_STATS then check again.

• Rename the table require re-run the stats?

  OS: OEL (last) 64-bit
  DB: 11 GR 1 material
  
  I need to create a copy of a large table A in production (call of the new table B). The data are the same, but the physical layout of the tables is different (different partitioning scheme is used between table A and B).
  When I go to move table B to replace table A (which will be eventually abandoned), should I raise his stats on table B?
  
  It's
  (1) table to become A_OLD
  (2) table B becomes table A
  
  I have to raise its stats on table A in step (2)? Is there something else that needs to be done?
  (I do this to limit the impact to the GUI that uses this table - the name of the final table does not change so the GUI should not be affected).
  
  See you soon!

  Yes, I have to raise his stats on the 'new' A table even if it has the same data and the name (after renaming) but different partitioning scheme (physical model)? It seems to me that the answer would be 'yes '.
  Otherwise, not the optimizer does not fail to recognize the new partitioning?

  (1) Board toys (all data) and table Toys_New (empty)
  (2) the Toys_New table is loaded with toys data table (the two tables have the same data - only difference is partitioning)
  (2) the toys table is renamed table Toys_Old (this will be served at a later date)
  (4) table Toys_New is renamed table Toys

  And I was thinking - I forgot to talk about first-hand - Toys_New will have the same indexes, but of course the clues will have unique names from toys (to avoid the error "object already exists".

  Given that the last note, I am convinced more than stats must be run on Toys_New after step (4)

  See you soon!

  Yes, you must.

  Name of your new table is 'Toys', but this new table is totally different than the old toys. If you need to analyze the table again.

  DR$ table do NOT need to be analysed - and should not be.

  As "secondary objects", they will not be analyzed by orders based on patterns, and it is strongly recommended to not analyze manually. All commands that access these tables are set correctly without the input of the optimizer.

• A search criterion and the result as a table in the header. Wanted to bind the result table to bean to access the value of the key

  The search criteria and the result is displayed in the table in a group header.  I want to get the value of the selected row and analyze the value of Vo in the next page for a variable binding. So I need to manage the value biniding to the bean tbal, but there is no option to bind the table to a bean. So, how can I get the selected value.

  Kind regards

  K M Krishna.

  First tell us your version of jdev, please.

  to get to the selected line you need not to link the table to a managed bean. You can for example drag the necessary attributes of the VO on the page and drop them as components of a inputText. the framework then generated the attribute bindings and sets the values of the current row for them. As you do not really need the inputText elements switch to source view (! it is essential!), then remove them. This will eliminate the Visual component, but attribute bindings are stored.

  Know you can access the values through their EL or as you get the value of an attribute via it's mandatory.

• SQL how to use a variable and use the result as a reference for the name of the table

  Hi all

  I have new in the declaration of Oracle, sorry in advance if something is easy for you all. BTW, I have this scenario:

  I have a table OL structured in this way:

  Date - it contains dates, for example 11/01/2015

  TableName - it contains strings, for example, OL1, OL2, OL3 and so on...

  Then I have a different table, the name of these tables are of the same name in the table of the OL, so I have table table, OL1, OL2, OL3 table and so on. The structure of these tables is the same. And Yes.

  table OL1

  If the scenario is clear, I would like to retrieve the value (null), research in all the OL * tables by using the value of the OL table (tablename) max.

  If I'm going to do these simple steps, I got the result:
