• Formula to calculate the SGA for 12 c of OLTP database

  Dear Experts,

  What is the formula to calculate the SGA for an OLTP database application.

  This will surely depends on several variables such as

  (1) the maximum number of connections application would have

  (2) growth of database

  • users connected
  • Server connections
  • total number of connections
  • connection memory
  • OS/application memory

  Thanks John.

  Is below the formula makes no sense?

  Why thank me when you don't know what I said:

  You will not find a formula.

  You formula has nothing to do with the numbers suggested for EBS, which could (only "might") be a reasonable starting point. You have not given any indication of how you arrive at these figures. You just apply that 80% of the RAM formula suggested by Mr. Faruq? If so, you might want to ask him how he justifies the algorithm.

  One point, that you should study management PGA. Your formula assumes that all connected sessions required 30 MB of RAM, all the time. How can you come to this conclusion? On your development system, you can observe how PGA is necessary for the optimal performance of your queries. Then you can ask "how many sessions is actually running a query at the same time?", adds on the non-negotiable PGA by session and calculate the requirement on the PGA TOUR as a result. You should also think about what you call ""memory connection ' and what you call 'PGA Pool'. " These aren't words that I know.

• How do we calculate the growth of the database?

  I have the situation where I have to calculate the growth of the database. I'm new to this business. We have implemented new indexes on the database of production where it took freespace all that remains. So, we have increased tablespace because we still have a few clues more to compile. Unfortunately, we ran out of space on the server. I asked for more space on the server that is to say 50% of the current database size. Of course, there are other databases on the same server and management wants to know why I need that a lot of space. Now my question is
  
  1. How do we calculate the growth of the database?
  2. How do we know how much table space is necessary for the given index.
  3. while maintaining growth increased from DB in calculating how we predict future growth.
  
  Any help much appreciated. Thank you.

  Rgds,

  do you mean that the materialized log should be created in the same location where the main table

  YES. Of course, it must be there! Any update to the main table should also update the MV log that is created against it!

• Calculate the space used in the database!

  Hi all
  
  I can calculate the space used by using one of the following ways:
  
  1. determine the size allocated by issuing
  
  SELECT SUM(d.bytes/1024/1024/1024)
  FROM dba_data_files;
  
  2 calculate the free space by issuing
  
  SELECT SUM(bytes/1024/1024/1024)
  from dba_free_space;
  
  Space used will be the value of the first statement - value of the second statement. This is manually!
  
  Is it possible to combine these two queries?
  
  Thank you!
  
  Dan.

  You can certainly combine queries

  SELECT (allocated.bytes - free.bytes )/1024/1024/1024 used_gb
    FROM (select sum(bytes) bytes from dba_data_files) allocated,
        (select sum(bytes) bytes from dba_free_space) free
  

  Normally, you could group tablespace as well.

  But if you want just the amount of space used, it is probably easier to just

  SELECT sum(bytes)/1024/1024/1024 used_gb
    FROM dba_segments

• Recommendations/suggestions for the material?

  Hi all

  I'm a little confused with what LabVIEW Embedded will work with. I read http://zone.ni.com/devzone/cda/tut/p/id/7066 , but that was not very useful because it tells me there are 260 aircraft but it lists only the 3 level 1 section (I guess that there are more than three). A research in the community gave no results. In the level 2 section, they are pointing to the keil device database, but it doesn't really help me either.

  I'm looking for a hardware platform like this http://www.gumstix.com/store/catalog/product_info.php?products_id=252 or this http://www.compulab.co.il/x270em/html/x270-em-datasheet.htm that will work with Embedded LV. I really don't want to design and build the hardware from scratch - I want to find something that will work for me for prototyping on shelf and it will also work for the small volumes of product.

  The problem is, how do I find something like that? Does anyone have the hardware recommendations? The cards Gumstix has an ARM A8 processor so I think he might be targeted by Embedded LV but I don't know. There is a post on this forum regarding the cards Gumstix but it refers to the microprocessor LV SDK and the replies to this post, it seems a very complicated if the process is impossible to implement the programming of LV on it. However, this post is old, and I understand that the SDK is no more.

  Any notice received with gratitude.

  Dr. Phil

  Hi Phil,

  As the Manu says, the best of the material of the plate for use with LabVIEW Embedded for ARM module are MCB2300, MCB2400, LM3S8962 Evaluation Committee.

  If I had to do your project, I probably used this material:

  Stellaris® Single Board Computer display Intelligent Module RDK

  LM3SXXXX family is easier to port of LabVIEW that family CAP because it uses pilot Stellaris.

  In addition, this material comes with examples that work on Keil µVision.

  However, you must create a new target and adds all the new features of LabVIEW. It can be difficult at the beginning.

• Trigger on the materialized view

  Hello

  I have the scenario based (Database 11 g):

  There is a view materialized (PERSON), which contains the ID and NAME fields. This MV is update daily with a fast refresh.

  I have a second array (NAMES), with ID and NORM_NAME. This table contains the name of the person, without special characters.

  For example, for recording / * 1 BJORN * / in the PERSON table

  I would check * 1 BJORN * / in table NAMES.

  
  

  Problem is how to fill the NAME table after the filling of the materialized view.

  I used a trigger AFTER INSERT or update, as described below, but even if I update the master table (for this purpose, update the MV), I have only to trigger inserts.

  
  

  Is there a way to implement a trigger "after update" on a materialized view, or do I need another approach?
  

  
  

  /*

  
  

  create or replace TRIGGER TRG_TESTE_MV

  AFTER INSERT OR UPDATE ON THE PERSON

  REFERENCING OLD AS OLD AGAIN AS NEW

  FOR EACH LINE

  BEGIN

  IF THE INSERTION

  INSERT THE NAMES

  VALUES

  (: NEW.id,:NEW.NAME);

  END IF;

  IF THE UPDATE CAN

  UPDATE OF NAMES

  SET NAME =: NEW.NAME WHERE ID =: NEW.id;

  END IF;

  END;

  */

  Thanks for any help

  Your trigger fires, but I doubted that you will be satisfied with the results. You really need to understand how to refresh process works before you begin creating triggers of MV:

  SQL > create table emp1 in select * from EMP
  2.

  Table created.

  SQL > create materialized view emp1 with rowid journal
  2.

  Materialized view log that is created.

  SQL > create materialized view emp1_mv
  2 fast refresh
  3 on request
  4 with rowid
  5 as
  6 select * from emp1
  7.

  Materialized view created.

  SQL > create or replace
  trigger 2 emp1_mv_biudr
  3 before inserting
  4 or update
  5 or delete
  6 on emp1_mv
  7 for each line
  Start 8
  9 insert then dbms_output.put_line ('INSERT' |: new.ename); end if;
  10 if the deletion then dbms_output.put_line ('REMOVE' |: old.ename); end if;
  11 end;
  12.

  Trigger created.

  SQL > insert
  2 in emp1 (empno, ename, sal)
  3 values(1,'X',1000)
  4.

  1 line of creation.

  SQL > validation
  2.

  Validation complete.

  SQL > set serveroutput on
  SQL > exec dbms_mview.refresh ('emp1_mv', 'f');
  INSERTION OF X

  PL/SQL procedure successfully completed.

  SQL > update emp1
  2 set sal = sal + 1
  3 where ename ('King', 'JONES')
  4.

  2 lines to date.

  SQL > validation
  2.

  Validation complete.

  SQL > set serveroutput on
  SQL > exec dbms_mview.refresh ('emp1_mv', 'f');
  INSERTION OF JONES
  INSERTION OF KING

  PL/SQL procedure successfully completed.

  SQL > delete emp1
  2 where in ename ('ALLEN', 'SMITH')
  3.

  2 deleted rows.

  SQL > validation
  2.

  Validation complete.

  SQL > set serveroutput on
  SQL > exec dbms_mview.refresh ('emp1_mv', 'f');

  PL/SQL procedure successfully completed.

  As you can see, refresh MV updates ever. Results update underlying table to remove/insert in MV. That's why your trigger will not give the results that you expected.

• Calculate the sum of the duration stored in format HH24

  Dear professionals,

  I use Oracle Database 11 g Enterprise Edition Release 11.2.0.4.0 - 64 bit Production. I stored length of certain events in the table TIME_DURATION as as follows (format h24:mi):

  CREATE TABLE "TIME_DURATION" ("ID" NUMBER(11,0), "HOURSMINUTES" VARCHAR2(5));
  
  Insert into TIME_DURATION (ID,HOURSMINUTES) values ('5','00:55');
  Insert into TIME_DURATION (ID,HOURSMINUTES) values ('7','00:18');
  Insert into TIME_DURATION (ID,HOURSMINUTES) values ('9','06:34');
  Insert into TIME_DURATION (ID,HOURSMINUTES) values ('15','00:12');
  Insert into TIME_DURATION (ID,HOURSMINUTES) values ('17','09:50');
  INSERT INTO TIME_DURATION (ID,HOURSMINUTES) VALUES ('41','12:39');
  

  select * from time_duration;
  
          ID HOURS
  ---------- -----
           5 00:55
           7 00:18
           9 06:34
          15 00:12
          17 09:50
          41 12:39
  
  6 rows selected.
  

  Now, I want to calculate the total time for all events (sum of all specific times). In this case, it should be 30 hours and 38 minutes.

  Any help would be much appreciated.

  Thanks in advance.

  Hello

  So, you want to add a number of lines varibale.  This sounds like a job for the SUM function.  AMOUNT of work on numbers, no channels such as time, so use TO_NUMBER to convert strings to numbers, so you can add them.  If you want to display the result as a string, you can use TO_CHAR to convert the sum into a string.

  WITH got_total_minutes AS

  (

  SELECT SUM ((TO_NUMBER (SUBSTR (heure, 1, 2) * 60)))

  + TO_NUMBER (SUBSTR (hour 4))

  ) AS total_minutes

  OF time_duration

  )

  SELECT TRUNC (total_minutes / 60). ':'

  || To_char (MOD (total_minutes, 60))

  , "FM00.

  ) AS total_hours_minutes

  OF got_total_minutes

  ;

  The output is not quite what you asked:

  TOTAL_HOURS_MINUTES

  --------------------

  30: 28

  If you really want 30:38', explain how to get it.

  This solution assumes that time always is always 5 characters (2 digits, a separator and another of 2 digits) as it is in your sample data.

  If your actual data aren't like your sample data, the same approach still works, but the SUBSTR expressions will be more complicated.

  Thanks for posting the CREATE TABLE and INSERT.

  ID is a NUMBER, so do not use quotes around it:

  Insert into TIME_DURATION (ID, TIME) values (5, ' 00:55 ');

  Insert into TIME_DURATION (ID, TIME) values (7, ' 00:18 ');

  ...

  Depending on how you plan to use the hour, you may want to store a NUMBER, also, or maybe an INTERVAL DAY TO SECOND.

• Re: view opaque and the materialized view

  Hi Experts,

  I want some clarification of opaque and view view in the physical layer OBIEE materialized

  -> I want the list of opaque opinion and materialized in the RPD view how I should do.

  I want some clarification of opaque and view view in the physical layer OBIEE materialized

  -> What is the main difference between opaque view and create the materialized view in the RPD point of view, we have to do this at the level of the RPD or DB.

  Opaque views is a SQL statement that is defined in the physical layer, OBIEE will use all in the construction of a SQL query. In a way it's not different from a database view, except it is set in OBIEE only. Alternatively, you can deploy an Opaque view, which pushes its definition in the database. Read more about it here: work with physical tables, Cubes and joins - 11 g Release 1 (11.1.1)

  A materialized view (MV) is a database concept where the results of a SQL statement are physicalised like a table, and therefore as OBIEE is a MV is just another physical array

  -> If I want a list of the opaque views and materialized in the RPD view how I should do.

  To find opaque views, use the function «Repository of applications» administration tool Search physical Tables and set up a filter on the Type = Select

  Screenshot: https://www.evernote.com/shard/s16/sh/5c843e47-bff1-4d4b-b847-be98f3a2ec09/cf060a6cd9805f687fa0b5b46f3f0020

  To find materialized views, you will need to query the catalog in your database (for example select object_name, object_type from user_objects where type_objet = "MATERIALIZED VIEW" ;) and compare it to the list of tables in your SPR)

  -> How opaque views will degrade the performance and how a materialized view will improve performance at the level of the report.

  A materialized view is materialized, in other words, the results are already stored in the database. This means usually there will be more efficient because all the joins and aggregations, etc. will be settled in advance.

• PL/SQL function to calculate the non-working days

  Hello

  I have the following pl/sql function which generates a number of days between two selected dates (i.e. excluding weekends). However, I also need to exclude specific holidays - day of Christmas etc. These holiday dates are stored in a table in our database (11 GR 2) called "HOLIDAY".

  How can I integrate the holidays which is held in the table of holidays in the following query to exclude these dates as well? I know how to write a separate funtion pl/sql for a number of days between two dates using SELECT... BUT I can't work out how to bring together them in a single query.

  Could someone show me how with the pl/sql / dates below please?

• Process of calculation to calculate the value after submit after all validations

  Hello

  Please help with a possible approach or suggestions for the calculation process.

  I have a calculation process after submit I want to calculate its value after that all validations are handled. Because this process of calculating trim is off of the first part of the input string of the user for the P3_USES element. Thus, for example consider; the user selects a value for P3_USES (point list manager) to be "TAC"... BCA... BCA... BCA... 0.CA BC... "CA IT BC. So my calculation process just stripes off the coast of the first portion of the string and computes the value will be "BCA"... BCA... BCA... 0.CA BC... "CA IT BC. It works fine when all postings on the page are placed without cooking.

  The problem occurs, then the validation fails on the form. Once the validation fails, the calculation process; already calculates the value and the P3_USES value form element is set to "BCA"... BCA... BCA... 0.CA BC... "CA IT BC. So, here the user solves the problem of validation and sends it again the form, but at this point the value is calculated again but this time that my string is "BCA"... BCA... BCA... 0.CA BC... CA IT BC"which is not correct, because my initial user string entry was"TAC"... BCA... BCA... BCA... 0.CA BC... "CA IT BC.

  So my question is how they treat the value of my calculation after all validations. While I can keep the original value of the P3_USES element. I'm using the version of Oracle APEX 4.0 and Oracle 10 g R2 database.

  Thank you

  Rambeau

• Try to calculate the size of the PAGE file

  This is an academic exercise. I am trying to determine why my PAGE file size is what it is. Currently, he is registered to 28,000,331 bytes. (He's alone). Here are the facts:

  3 dense dimensions, stored members are 17 * 20 * 5, for a total of 1,700 * 8 = 13 600 bytes.

  The actual maximum blocks are 19 800. The maximum reported are 24 750.

  I have disabled compression for ease of calculation.

  There is only 1 block no missing.

  I use SER60 as my guide in the section estimate disk and the memory required. However, when I use the planned calculation:

  Number of blocks * (size of data block expanded + 72 bytes)

  I don't get anywhere near the number of bytes listed for the PAG file. I realize that I am not to mention the rest of the database files and do not know if this calculation is only for the PAG files or all files. I am not very interested in the size of the entire database, just the file PAG. So my questions are:

  1. is the calculation provided for all files or just the file PAG?

  2. If the answer to 1 is Yes, is there a separate calculation, that I can use to determine the size of the PAGE file only?

  Take a look at NUMBLOCKSTOEXTEND in the technical reference on Essbase.  We had a long conversation that addressed this issue on Network54 recently: http://www.network54.com/Forum/58296/thread/1374608752/11-1-2-2+Fragmentation

  Short answer is that Essbase allocates file space .pag in 2048-block pieces, which is the default value of NUMBLOCKSTOEXTEND 11.1.2.2.  Calculate how many blocks (including header block 72 bytes) integrate 28,000,331 bytes and you will see that this is almost exactly 2048.

  With compression on it more difficult (for me, at least) to understand how Essbase arrives with the size of the average disk blocks to use as the size on the disk with compression on is not constant.

• Function to calculate the Minutes of business between two Dates

  Hello

  I use the version of database Oracle 11.2.1. I would like to calculate the number of minutes of work between the two dates where working hours are Monday - Thursday from 08:45 to 17:00 and Friday from 08:45 to 16:30

  I found the following function useful in a similar position but wanted help picking up the days and the hours above into account

  CREATE OR REPLACE
  FUNCTION get_bus_minutes_between(
                                   p_start_date DATE,
                                   p_end_date DATE
                                  )
    RETURN NUMBER
    IS
        v_return NUMBER;
    BEGIN
        with t as (
                   select  case level
                             when 1 then greatest(p_start_date,trunc(p_start_date) + 9 / 24)
                             else trunc(p_start_date) + level - 15 / 24
                           end start_dt,
                           case connect_by_isleaf
                             when 1 then least(p_end_date,trunc(p_end_date) + 18 / 24)
                             else trunc(p_start_date) + level - 8 / 24
                           end end_dt
                     from  dual
                     connect by level <= trunc(p_end_date) - trunc(p_start_date) + 1
                  )
        select  sum(greatest(end_dt - start_dt,0)) * 24 * 60 work_minutes
          into  v_return
          from  t
          where trunc(start_dt) - trunc(start_dt,'iw') < 5; -- exclude weekends
        RETURN v_return;
END;

  Can anyone help?

  Hello

  Think about what you do.

  sliderrules wrote:

  SELECT TO_CHAR (DATE ' 1-1-1' + business_end_time, 'HH24:MI:SS')-TO_CHAR (DATE ' 1-1-1' + business_start_time, 'HH24:MI:SS') * 24 * 60

  of time_dim

  where full_date = July 1, 2013.

  AND working_day = 'Y ';

  The following error is returned:

  ORA-01722: invalid number

  The time is converted to character reslting with this error. Is there a better way to subrtacting types of data INTERVAL DAY (1) SECOND (2) (business_end_time - business_start_time)

  To_char, as its name implies, returns a string of characters.  You say that

  TO_CHAR (...) - TO_CHAR (...) * 24 * 60

  If you ask for the string returned by the 2nd TO_CHAR be multiplied by 24.  Does make any sense to you?

  Maybe you wanted to do the subtraction first, which would be

  (TO_CHAR (...) - TO_CHAR (...)) * 24 * 60

  but still would be a mistake, because you can't subtract a string to another string (or anything else).

  .

  Last Friday, I proposed this:

  SELECT SUM (LESS (end_dt, v_end_dt)

  -Most GREAT (start_dt, v_start_dt)

  ) * 24 * 60...

  where start_dt and end_dt were the DATE in the table columns, as the value returned by TO_DATE (08 11 July 2013:45 ', "DD-Mon-YYYY HH24").

  If I understand correctly, you would store stores rather 3 columns: full_date (a DATE, where the time part is 00:00:00) as well as business_start_time and business_end_time (the two INTERVAL DAY TO SECOND).  In this case, you can modify the code above to say:

  SELECT SUM (LESS (full_date + business_end_time, v_end_dt)

  -GREATEST (full_date + business_start_time, v_start_dt)

  ) * 24 * 60...

  You can add a DATE at an INTERVAL;  the result will be a DATE.  There is no need to convert anything to a data type to the other.
