• ODI 12 c: do I have to reimport the target tables after that I did some clues on them

  Hello

  I created a map after import target tables in my ODI 12 C studio. The mapping is complete and it works without any errors. Now I intend to create some clues that I have an obligation to report. SO, I have to reimport these after creating indexes.

  Thank you

  SM

  Hello

  Here's the thing. The indexes that you created, if you plan to use as a unique index, or as your key to updating ODI you can go ahead and add the template manually in or hit the table again. However, if these indices are purely to make your report more quickly and will have no impact on you data loading then it is pointless to ODI. In the future when you make changes to the table and refresh it in ODI indexes will be added automatically.

  Thank you

• ODI 12 c: IKM for differential insert and update with a sequence in the target table

  Hello

  I have a map where I fill in a column of my target table using a database sequence. Now my mapping is supposed to load the target gradually table. So I need a revenge for update and incremental insert. Now with this differential IKM it compares all the columns to match all colmuns line to understand, it should be an insert or update. Now, the following code shows that when the ROW_WID is loaded with a sequence of database.

  If NOT EXISTS

  (select 1 from W_LOV_D T

  where T.ROW_WID = S.ROW_WID

  and ((T.CREATED_BY = S.CREATED_BY) or (T.CREATED_BY IS NULL and S.CREATED_BY IS NULL)) and

  ....

  ....

  < the rest of the comparison of columns >

  )

  So when running ODI returns following error

  Caused by: java.sql.SQLSyntaxErrorException: ORA-00904: "S". "" ROW_WID ": invalid identifier

  Please suggest if there is no other IKM I should use or if there is another way around it without changing the code IKM...

  Hi Marc,

  Thanks for your reply.

  I had solved it. The incremental update process inserts all rows from the source table to I$ table that exists in the target table. It does so by the where sql such as mentioned in my questions as

  WHERE THERE is NOT ( . COLUMNS = . COLUMNS)

  Now in the incremental update IKM Oracle to retrieve all the columns it uses the substitution with parameter as TABLE TARGET. Due to this column sequence will in the comparison and the request fails. When I used the IKM SQL incremental update it used INTEGRATION TABLE as parameter table to pick up the columns, as I'd mentioned in the target sequence is run, so it does not get the sequence column.

  Simple answer: to solve this, use incremental update of the SQL IKM.

  Thank you

• The logged data is not loaded in the target table in cdc-compatible?

  Hello

  I tried with cdc-simple concept on single table.

  I had loaded, journaled table (only changed records) inserted in the simple target in cdc table. Its working fine.

  When I work on cdc-consistent and logged data are not loaded in the target table

  For this, I used the data model, it has 3 data stores. log the without option of data, its works very well.

  When I am trying to load tables logged in the target table in interface, its running fine.

  To do this, I chose "logged data only.

  Although I have not changed the records in the target table. target table is empty after the executed insterface.

  

  

  

  

  I chose the real option of insertion in ikm. But the logged data that is not inserted in the target table.

  Please help me.

  Thankin advacnce,

  A.Kavya.

  Hello

  You must EXPAND WINDOW and LOCK SUBSCRIBERS before consuming the CDC data:

  http://docs.Oracle.com/CD/E14571_01/integrate.1111/e12643/data_capture.htm#ODIDG283

  Subsequently, you unlock Subscriber and purge the log.

  Better to put a package to automate the whole thing.

• Failed to truncate the target table while programming the interface in ODI

  Hi Expertise,

  I developed a scenario in an interface, where I planned keeping the option Truncate as false, right there the data is been going to target without any problems, but when I changed the status of truncate to TRUE, the interface is been run, but the array is not get truncated, rather the data's been loading again to target. (when running manually, the target table is been truncated perfectly) but not in programming.

  Can someone help me in this problem.

  Thank you

  Shakur.

  Have you regenerate the scenario in question since you changed the option Truncate. If you have not the regular job must still run the old code

• How to MERGE when the target table contains invisible columns?

  Oracle running on Oracle Linux 6.4 12.1.0.2.0 database:

  During his studies of FUSION with invisible columns, I discovered that invisible columns in the target table cannot be read. Workaround seems to be

  MERGE INTO (SELECT <column list> FROM <target table>) AS <alias>
  

  However, the documentation does not seem to allow this. Here are the details.

  Test data

  > CREATE TABLE t_target(
    k1 NUMBER PRIMARY KEY,
    c1 NUMBER,
    i1 NUMBER invisible
  )
  
  table T_TARGET created.
  
  > INSERT INTO t_target (k1,c1,i1)
  SELECT 2, 2, 2 FROM dual
  UNION ALL
  SELECT 3, 3, 3 FROM dual
  UNION ALL
  SELECT 4, 4, 4 FROM dual
  
  3 rows inserted.
  
  > CREATE TABLE t_source(
    k1 NUMBER PRIMARY KEY,
    c1 NUMBER,
    i1 NUMBER invisible
  )
  table T_SOURCE created.
  
  > INSERT INTO t_source (k1,c1,i1)
  SELECT 1, 1, 1 FROM dual
  UNION ALL
  SELECT 2, 2, 9999 FROM dual
  UNION ALL
  SELECT 3, 3, 3 FROM dual
  
  3 rows inserted.
  

  First try

  Please note that I have a WHERE clause in the WHEN MATCHED clause. Its purpose is to avoid the update of a row when data are already correct. The WHERE clause is trying to read the invisible column of the target table.

  > MERGE INTO t_target o
  USING (
    SELECT k1, c1, i1 FROM t_source
  ) n
  ON (o.k1 = n.k1)
  WHEN MATCHED THEN UPDATE SET
    c1=n.c1, i1=n.i1
    WHERE 1 IN (
      decode(o.c1,n.c1,0,1),
      decode(o.i1,n.i1,0,1)
    )
  WHEN NOT MATCHED THEN INSERT
    (k1, c1, i1)
    VALUES(n.k1, n.c1, n.i1)
  ...
  Error at Command Line : 10 Column : 12
  Error report -
  SQL Error: ORA-00904: "O"."I1": invalid identifier
  

  As you can see, I put a subquery after the USING clause so that 'n.i1' would be 'visible', but this is not enough since the 'I1' column in the target table is always invisible.

  Second test

  > MERGE INTO (
    SELECT k1, c1, i1 FROM t_target
  ) o
  USING (
    SELECT k1, c1, i1 FROM t_source
  ) n
  ON (o.k1 = n.k1)
  WHEN MATCHED THEN UPDATE SET
    c1=n.c1, i1=n.i1
    WHERE 1 IN (
      decode(o.c1,n.c1,0,1),
      decode(o.i1,n.i1,0,1)
    )
  WHEN NOT MATCHED THEN INSERT
    (k1, c1, i1)
    VALUES(n.k1, n.c1, n.i1)
  
  2 rows merged.
  

  Here I used a subquery in the INTO clause thus, and it worked.

  Unfortunately, this does not seem to be admitted in the documentation: IN fact refers to a table or a view as schema objects.

  

  My question is:

  How can I refer to invisible columns in the target table without creating a new object? My workaround using a subquery solution seems to work very well, but can I recommend if it is not documented?

  Can I replace a "inline view" for a view and still be supported?

  But the documentation DO ALLOWS not only! You use a view - a view online and those that can be changed in a MERGE statement.

  All versions of the doc for FUSION since 9i specifically say this:

  INTO clause

  Use the INTO target clause to specify the table or view you are updating or inserting into. To merge the data in a view, the view must be updated. Please refer to the "Notes on the editable views" for more information.

  Here are the links for the doc. 9i, 10g, 11g and c 12, ALL OF THEM (the last three), except 9i have this EXACT clause above.

  SQL statements: INDICATED to ROLLBACK FALLS, 15 of 19

  http://docs.Oracle.com/CD/B19306_01/server.102/b14200/statements_9016.htm

  http://docs.Oracle.com/CD/B28359_01/server.111/b28286/statements_9016.htm

  https://docs.Oracle.com/database/121/SQLRF/statements_9016.htm

  9i doc does not have this specific quote in the INTO clause section, but it doesn't have that quote a little later:

  Limitation of the update of a view

  • You cannot specify DEFAULT when refreshing a view.
  • You cannot update a column referenced in the ON condition clause.

  merge_insert_clause

  The merge_insert_clause specifies the values to insert into the column of the target table, if the condition of the ON clause is false. If the insert clause is executed, then all insert triggers defined on the target table are activated.

  Restrictions on the merger in a view

  You cannot specify DEFAULT when refreshing a view.

  If your "workaround" isn't really a workaround solution. You SHOULD use an inline view if you need to reference a column "invisible" in the target table, since otherwise, these columns are INVISIBLE!

  My workaround using a subquery solution seems to work very well, but can I recommend if it is not documented?

  You can recomment it because IT IS documented.

• A target table is in charge of two different sources but the same columns, but a source is one database and another in a flat file.

  We all hope you are doing well.

  I have a business problem to implement in ODI 11 G. It's here. I'm trying to load a target table from two sources that have the same column names. But a source is to the file format and the other is in the Oracle database.

  That's what I think I'll create two mappings in the same interface by using the Union between the sources. But I don't know how the interface would connect to different logical architecture to connect to two different sources.

  Thank you

  SM

  You are on the right track, all in a single interface. Follow these steps

  (1) pull model of your data in the designer of the source file and your table model target to the target pane.

  (2) all relevant columns map

  (3) in the source designer to create a new dataset and choose as the UNION join type (this will create a separate tab in the source designer pane)

  (4) select the new dataset tab in the source designer pane and pull your source oracle table data model in the designer of the source. All columns that are relevant to the target card

  (5) make sure that your staging location is set to a relational technology i.e. in this case the target would be an ideal candidate because it is where the ODI will organize the data from source two files and oracle and perform the UNION before loading to the target

• Need to load jobs parallel to the load on the same target table plan

  Hello

  We need loading parallel work on the same target table. We use LKM and IKM in our interfaces on the target.

  I have a questions if run us jobs in parallel on the same target table is executed both the process of creation, insertion and drop tables mixed obtained work and will be causing problems.

  Please guide us recommended to implement on the same parallel load of target

  Concerning

  Naren

  HI Naren,

  Yes, out of the box your (temporary) work tables will be taken upwards and cause a failure in the treatment. Take a look at this post on the parallel of loading in ODI12c https://blogs.oracle.com/dataintegration/entry/odi_12c_parallel_target_table. It also has a link to a solution for ODI11g if you're on this version.

• GET A DATE THE TARGET TABLE MAX

  Hello friends,
  
  Can someone tell me how to extract the date max of the target table.
  
  Thank you.

  Azhar

  Sorry why again once you are not able to use the aggregator operator to get a max value. You don't need a group of when taking a max value what from a table, unless otherwise specified

  Try it with a simple table b table card

  table (several itemno)

  table b (number maxitem)

  Use aggregator and don't put anything in the section of owb agg transformation group. Generate the code and take a look

• delete all, then insert into the target table, two steps in one transaction?

  Hello
  
  We have the following two steps in one ODI package, it will be managed in a single transaction?
  
  procedure step 1): remove all of the target table.
  interface in step 2): insert data in the source table in the target table.
  
  our problem is that step 2 can take some minutes, and then the target table can temporary unusable for end users who try to access it, I'm good?

• Risks and impacts on the changes in the physical and logical structures used in ODI

  What are the risks and impacts on the changes in the physical and logical structures used in ODI?
  
  
  I wonder what can be changed and the risks and impacts that may occur changes in the physical and logical structures used in projects of ODI?

  You should not change the name of logic. Because in ODI, each model is connected to a logic diagram.
  You shouldn't be changing technology too because that would need a change to all models and the KMs that have been used in the development of interfaces and procedures, etc.

  Nothing under the physical schema can be changed for example. Connection, user, etc.
  ODI uses the logical schema. And it matches the physical schema in the runtime using contexts.
