• Which way is the best instantiate the Table level replication tables

  Hello

  Find the RCS of the source, and set if for all tables by using the dbms_apply_adm.set_table_instantiation_scn API.

• Of many level replication table

  Hi all
  
  I was configuration of replication of flow between a table at many tables (3) in the same database (10.2.0.4)
  

  Below figure states my requirement.
  
                                      |--------->TEST2.TAB2(Destination)

• Merits and demerits of the replication of schema-level and Table

  Hello
  
  We evaluate the streams for our needs of replication. We reproduce nearly 2000 two-way tables. Most of the tables are in a schema. The main schema has a few tables that are not replicated.
  
  Replicate us schema level? Or at the level of the table? What are the advantages and disadvantages?
  
  Replication of level schema included with a handful of exclusionary rules seems simpler.
  
  In water courses at the level of the tables as well as creating 2000 table rules in the beginning, add a new table to an existing configuration of streams, will require additional steps to stop capture/apply/spread, creating new rules for the new table and restart replication. However, it seems that level replication table offering flexibility in terms of group tables. We wanted to group tables about 10 groups of 20 to 300 tables in each group. Each group will have its own capture, propagate and apply. In this way, we can isolate large groups of those unimportant?
  
  Who is a better setup in terms of maneuverability, flexibility, parallelism and performance?
  
  Thank you.

  Hello Stargaze,

  OK, so I understand that the grouping is based on the type of transactions and its importance. In this case the grouping would help you in many ways such as:

  1. If you encounter a problem or a bug with one of the processes of capture/apply then the other groups would work fine. Therefore, you have the opportunity to shoot a game of capture, propagation and applies until solve you the problem.

  2. in case if you perform any load batch where the transaction will affect over 10000 + records then it is possible that you could get stuck at 'SUSPENDED for FLOW CONTROL' on any of the feed items. With different groups would give you more flexibility to solve this problem by activating and deactivating groups.

  For more information on this please check the following:

  Apply process is active, inactive, and just stopped in change application

  3. with the schema level replication even if you have the advantage of being simple and have fewer rules in the set of rules, you must consider the 2 points above before you implement it. You need to test both diagrams and tables with a typical load (simulation of the production) and need to identify potential problems in both. Some more points to consider:

  -apply the game patches 10.2.0.4 or at least 10.2.0.3
  -apply all the patches required streams (Note: 437838.1> on metalink)
  -follow the recommendations as indicated:
       Note: 418755.1 broadcast 10.2.0.x.x of recommendations
       Note: 335516.1 Performance of flow recommendations
  Note: 413353.1 10.2 best practices for streams in RAC environment

• Two-way replication in two databases in a single server

  I have two instances of installation OGG, one for each database. Let's say that they are respectively OGG1 and OGG2 for DB1 and DB2. Ogg1 has two extracts and OGG2 has 1 replicat for replication of the first. It works well independently.  OGG2 has two excerpts and OGG1 1 replicat for replication of the second, which is for the direction of backword. It also works well independently. As I got to know previously, this is how I do two-way replication, by running these two processes together. I did it.

  But when I did, it gives me the desired result. What currently happening given cannot be changed in one of the databases. When the data changes, it shows the change. but when committed, itself data is modified in its original values. What's the harm? Two processes works well independently.

  
  

  ORASCN Hi Vicky, you were the subject of this question with me. It's good if you can have a look.
  

  Yes, that was the problem. I added "TranLogOptions ExcludeUser ogguser" the main excerpt from two replications. ogguser is my user goldengate.

  Extract einta1q

  SETENV (ORACLE_SID = "dd")

  UserIdAlias ogg_user

  TranlogOptions IntegratedParams (max_sga_size 256)

  TranLogOptions ExcludeUser ogguser

  Exttrail ./dirdat/ip

  LOGALLSUPCOLS

  UPDATERECORDFORMAT COMPACT

  Table SC2.*;

  Now looping does not occur. Replication is as expected. Thank you.

• Is it possible to create two-way multiselect tables? Help.

  Hey everyone (once again since you're indeed great to help me to).

  I was wondering if it would be possible to create two-way multiselect tables to interact with each other, as qlikview behavior have, because that's my goal.

  Imagine that I have 3 tables in my schema/database:

  Departments (of an HR diagram), with the following attributes: department_id (primary key), department_name, manager_id, location_id;

  Salary_by_job (created for this purpose), with the following attributes: job_id (primary key), department_id, salary, min_salary, max_salary;

  Employees (from HR diagram), with the following attributes: employe_id,..., job_id, salary, manager_id, department_id

  Would it be possible to creat multiselect two-way tables?

  Like the following:

  -I click on a Department, it shows the data relevant to this Department in the table salary_by_job and the employees table.

  And after having clicked on that, I could click on a single employee and the department table would be the same (because it's an employee in the same Department), but the salary_by_job would show only the information about the argument job_id for this employee.

  I'll try to show some text here:

  Department (selected line = 1) = Department of Public Information (which has 3 employees)

  Employees = X (with the job_id = adminargument), are (with the job_id = managerargument) and Z (with the job_id = Internargument)

  Salary_by_job = Admin, with data blah blah blah, Manager, with data blah blah blah and trainee, with data blah blah blah

  And then I have to click on the X of the employee and the result would be:

  Department (selected line = 1) = Department of Public Information (which has 3 employees)

  Employees = X (with job_id = adminargument)

  Salary_by_job = Admin, with data blah blah blah

  Can do something like this? If so, how?

  I think attached with fasteners at each table and have links to move forward and backward.

  If anyone has an idea how to do this, please respond, it may be useful.

  Thanks a lot for all the help. Have a beautiful day!

  Kind regards

  Frederico Barracha.

  BTW, I use jdeveloper 12.1.2.0.0

  Mensagem editada por: FredericoSB

  FredericoSB,

  Have you tried to add a setPropertyListener for tables and change the collectionModel to the 3rd table accordingly?

  Ex: Suppose you have three tables, Parent (VL)-> child (VL)-> grandchild. There is a relationship between the (VL) Parent-> child.

  Now, you can have links to tree for both the GrandChilds (for example GrandChildViaParent and GrandChildViaChild).

  Your jspx could be something like

  If all your tables are read-only, then you can change it to something like

  This is just a sample. You could implement the same for all properties in the table of a grandchild as EL to make editable as well.

  It comes without coding. If you care to code a little, you could use a dynamic array in place and tie the value accordingly in each of the selectionListener in the table (that would be a neat approach)

• Help with Ora-19046: Out-of-table row cannot be shared by two top-level tab

  Hello!
  My tutor asked me to store and query xml "natively" files in xml db. First, I tried to save the patterns that rely on these xml files. There are about 30 patterns thus between them, and I have to use 'FORCE' them to save, like this:
  
  BEGIN
  () DBMS_XMLSCHEMA.registerSchema
  "http://www.isotc211.org/gmd/metadataEntity.xsd,"
  BFILENAME ('ISOGMD', 'metadataEntity.xsd'),
  TRUE,
  TRUE,
  FAKE,
  TRUE,
  (TRUE);
  END;
  
  So no tables are created automatically. And when I wanted to create a XML based on patterns of thses manually, he proped error: ORA-19046: Out-of-table row cannot be shared by two top-level tab. He mistook me for a week. Does anyone know what is the problem with registration? Forward online! Thank you!

• Skip a level of table

  Hi, I have these 3 tables (right FKs and joins) in my Dimension product:
  
  CITY, SUPPLIER, PRODUCT.
  
  The right hierarchy should be high in leaves: City-> provider-> product
  
  We would like to build the hierarchy of these dimensions:
  
  City-> product, but we get this warning in BI Admin (and the error then in the answers)
  
  [39008] logical dimension CITY table has a source of the CITY who do not adhere to any source of fact.
  
  It cannot sail in joins, the level of the intermediate jump table?
  Are we obliged to build the whole hierarchy and spend level (and table) defining a privileged way of exploration? (this solution worked)
  
  Thanks in advance!

  To resolve this problem, you have two options.

  Don't forget that you have in the correct join FK relationships of physical layer between these tables as follows:

  City-<><>

  In the MDB do logical table (dimension table) with source logical table product. Now, in the source of the product logic table properties general tab add physical tables and joins (add first table beg and join product >-provider, and then add the picture of the city and join provider >-City). Now, drag - move the columns in all tables that you want to use in the levels in the dimension.

  Build the dimension with levels object and columns on each level.

  Option 1 (all three levels):

  The city level: use for drilldown checked key
  Provider level: use for the uncontrolled descent of key
  Product level: use for extraction of key checked or unchecked

  Now you can dig in the answers given by the city to the product, the intermediate level is not displayed, obiee do reach across the three tables.

  Option 2 (city and produced only in levels):

  The city level: use for drilldown checked key
  Product level: use for extraction of key checked or unchecked

  Now you can dig into the responses made by the city to the product, obiee do reach across the three tables, because you set this additional physical tables and joins in logical table product source.

• Dynamic calculation of the number of days between two dates in a table

  Hello

  I'm working on request where I dynamically calculate the number of days between two dates in a table.

  The calculation must be dynamic, i.e., when I recover the Start_date and End_date and move to the field following (call_duration) in the same row, the difference must be calculated dynamically in this area and make sure the field read-only.

  APEX version: 5.0

  APEX version: 5.0

  one of the way to do this by calling ajax on change of end_date.

  See the sample code given below to fetch the resulting duration and making the field read only after calculation

  Step 1: Change your page

  under CSS-> Inline, put the code below

  .row_item_disabled {
    cursor: default;
    opacity: 0.5;
    filter: alpha(opacity=50);
    pointer-events: none;
  }
  

  Step 2: Create on demand Ajax process I say CALC_DURATION

  Please check Procces Ajax, see line 6.7 How to assign a value to the variable sent by ajax call

  Declare
    p_start_date  date;
    p_end_date    date;
    p_duration number;
  Begin
    p_start_date  := to_date(apex_application.g_x01);
    p_end_date    := to_date(apex_application.g_x02);
  
     --do your calculation and assign the output to the variable p_duration
    select p_end_date - p_start_date into p_duration
      from dual;
  
    -- return calculated duration
    sys.htp.p(p_duration);
  End;
  

  Step 3: Create the javascript function

  Change your page-> the function and the declaration of the Global Variable-> put the javascript function

  You must extract the rowid in the first place, for which you want to set the time, see line 2

  assuming f06, f07 and f08 is the id of the start date, and end date columns respectively, and duration

  See no line no 8 how set the value returned by the process of ajax at the duration column

  Replace your column to the respective column identifiers in the code below

  function f_calulate_duration(pThis) {
    var row_id  = pThis.id.substr(4);
    var start_date = $('#f06_'+row_id).val();
    apex.server.process ( "CALC_DURATION", {
    x01: start_date,x02: $(pThis).val()
  }, { success: function( pData ) {
  // set duration to duration column
  $('#f08_'+row_id).val(pData);
  // disable duration column
  $("#f08_" + row_id).attr("readonly", true).addClass('row_item_disabled'); }
  });
  }
  

  Step 4: choose the end date call the javascript function

  Go to report attributes-> edit your Date column end-> column-> Attrbiutes element attributes-> put the code below

  onchange="javascript:f_calulate_duration(this);"
  

  
  

  hope this helps you,

  Kind regards

• Works with tables/columns of the lines and the parameter names... syntax help

  I am trying to create a function that returns the distinct value and counts of a user defined schema/table/column.

  The code below defines a [stats_on_column_obj] object type and creates a single table of this type [stats_on_column_tab].

  The function is supposed to take three input variables: p_schema_name, nom_table_p, p_column_name and return an array (above).

  I can hardcode a select into (the)... but once I try to convert it into settings & immediate exec I'm stuck. The red section is where the problem is (I think).

  Oracle 10g.

  Stats_on_column_obj CREATE TYPE IS OBJECT (

  COL_VAL VARCHAR2 (500),

  NUMBER OF COL_VAL_CNT (7)

  );

  CREATE TYPE Stats_on_column_tab IS TABLE OF stats_on_column_obj;

  
  

  FUNCTION to CREATE or REPLACE get_STATS_ON_COLUMN

  (

  p_schema_name IN varchar2,

  nom_table_p IN varchar2,

  p_column_name IN varchar2

  )

  RETURN STATS_ON_COLUMN_tab

  IS

  FOR r IN (str_select_tbl)

  LOOP

  l_STATS_ON_COLUMN_tab. EXTEND;

  n: = n + 1;

  l_STATS_ON_COLUMN_tab (n): = STATS_ON_COLUMN_obj (r.col_val, r.col_val_cnt);

  END LOOP;

  RETURN l_STATS_ON_COLUMN_tab;

  END;

• Mobile table column

  I am able to add a column to a table through SQL Workshop Object Explorer. The column is added at the end of the table.
  
  However, I don't see any way to move the column added to a position in the table. It is possible to move a table column in the Apex, or do I have to use another tool?

  Hello

  You can't change order of column in the tables. New columns always comes last. And it's not Apex, the Oracle database operation.

  If you rearrange the columns, change the name of the table.
  Create the new table with the old order of columns name and correct.
  Insert the new renamed table table data and then drop a renamed table.

  Kind regards

• Any way to edit tables in Textedit or Bean?

  Hello

  I used to use LibreOffice as my preferred burning software but I have questions of sensory processing, strobe and migraines, so I need to ripheriques in order to avoid painful flashing cursors. The demo Pages and NeoOffice, OpenOffice have similar flashing cursors. TextEdit and Bean allow users to turn off blinking cursors if we used the terminal hack to change their schedule.

  Unfortunately, I can't change the tables in Textedit and the bean. I can add or delete rows and columns at the end, but not between existing lines, and I can't copy and move a block of existing lines either.

  Can anyone suggest a way to edit tables in Textedit or bean or other compatible software without flashing cursors?

  My latest project docs are odt and my next will probably be in rtf.

  Thank you!

  (display using OS X El Capitan and crossposting to accessibility because the flashing is a Visual accessibility issue, at least for me).

  Right click-> add a line above works now at the bean. Nothing like it in Textedit.
