• Number of databases such as Oracle and SQL Server in the same application ADF

  Hello
  
  In my application, I need to use two different databases such as Oracle and SQL Server. There are screens that I need to develop in the ADF where I need to involve fields of the tables in these two different databases. I just want to know - is it possible to do so in application of the ADF?
  
  Or to create a sort of link between these databases in the backend? Then create a view object involving some distributed SQL queries. What can I do with this type of request than anything? I mean, can I use the two insert or update operation using this VO?
  
  Or y at - it another way to do this?
  
  Please help, help here would be really appreciated. I've been stuck with this problem for a while now. I did search our forums for the same problem, but was not able to find a reliable solution.
  
  Thank you
  Vijay

  It's still not clear to me if you need two db tables in a query, or a transaction.
  If this is the case, your best option (to my knowledge) is to use a db link. in this way, you only need to access (for example the oracle db) and can access the objects from the other data from the oracle database.
  I don't understand

• Unlike char in ORACLE and SQL SERVER

  Hello gurus,
  
  I tried to querying data from Oracle to sql server through linked server, but get me an error! set length corresponds to the error! I know there are CHAR data type in sql server and thus as in oracle.
  
  But when I use the CAST FUNCTION with CHAR it works fine
  

  -- error code 
  
    select * from openquery( linkoracle11 
             select  col1, col2, col3 from test_table )
  
  
  -- say col3 char(1)   -- data type

  ---
  
  

  -- working code 
  
    select * from openquery ( linkoracle 11 
             select  col1, col2, cast (col3 as char(1)) as col_3 from test_table )

  I was wondering, what is the difference between oracle and sql server for the CHAR data type?
  
  The gurus of the idea?
  
  Thank you

  What is the error you get?

  What is the characters in database and NLS_LENGTH_SEMANTICS game on your Oracle system?

  SELECT *
    FROM v$nls_parameters
   WHERE name LIKE '%CHARACTERSET';
  
  SQL> SHOW PARAMETER nls_length_semantics;
  

  What is the character set of data in SQL Server?

  If your local database is a variable length character set (like UTF8) and NLS_LENGTH_SEMANTICS is set to (default) BYTES, a char (1) allocate 1 byte of storage which may not be sufficient for a single character. The receiving application may need to allocate a buffer with 3 times more many bytes as there are characters in order to ensure that it will be able to process the result. I don't know why add an implicit CAST that would change, but since we are several levels removed from the code to figure out how large a buffer to allocate, it is not very surprising.

• Sort of the differences between Oracle and SQL Server

  Hi all
  
  This question is linked by both Oracle and SQL Server
  
  I have a requirement where I want to compare 2 tables line by line. A table is in Oracle and other table in SQL Server
  
  And suppose that both tables do not have a primary key. Now when I sort records by using the order by clause for a column, then-
  
  Rows with null values in that column of Oracle are placed in the background.
  When that rows with null values in the same column in SQL Server are placed right at the top.
  
  How can I make one of them to behave like any other.
  
  My only goal is to have same order of lines in Oracle and SQL Server tables so that I can compare line by line.

  YADQ: Yet another Doc Question

  Can you please avoid them?

  Take your SQL reference manual, search for the ORDER BY clause and notice that it has
  NULL FIRST or LAST values NULL values.

• Need help to write to Oracle and SQL Server in the Oracle triggering

  We have a third which feeds data for us. Their client application feeds directly to some source tables in our Oracle database 10g. We have triggers on those tables that sort and treat lines as they come.
  
  We have a new operation and try to write some of these incoming data now to a SQL Server database through heterogeneous services - essentially the same exact data in two databases. I have a related database that works very well for the selection, but I've never tried to write Oracle PL/SQL to write in a DB SQL Server 2008. My first attempt was met with the following error: "ORA-02047: impossible to join the current distributed transaction.
  
  I found another thread where they say that the only way to do it is by using a stand-alone transaction, but they do not give an example. Here is the section of relaxation that I use:

    select to_char(new_date,'MM-DD-YYYY') into sql_txt from dual;
    insert into mancamp_location@sqlweb
         ("UnitID", "ManCampID", "Lat", "Long", "UpdateDT", "VehSpeed", "VehDirection", "Landmark")
      values (v_truck, f_unit, f_lat, f_long, sql_txt, f_spd, f_dir, f_ldmk);

  Can someone point me to a way to accomplish this simple insertion?

  An example of a standalone trigger is:

  Suppose you have a table in Oracle:

  CREATE TABLE emp_sal
  (
  EMPNO NUMBER 4,
  SAL NUMBER (7.2));

  and a similar table in a SQL server:
  SQL Server:

  CREATE TABLE emp_sal
  (
  EMPNO NUMERIC (4).
  SAL NUMERIC (7.2));

  Then, you can create an insert trigger that replicates the data:
  CREATE OR REPLACE TRIGGER dg4odbc_repl AFTER INSERT ON emp_sal
  FOR EACH LINE
  DECLARE
  PRAGMA AUTONOMOUS_TRANSACTION;
  BEGIN
  INSERT INTO 'emp_sal"@MSODBCSQLSERVER_DG4ODBC_EMGTW_1123_DB '.
  VALUES (: new.empno,: new.sal);
  COMMIT;
  END;
  /

  -Note the validation, otherwise risk of ORA-6519

  When you now insert a record into the Oracle database:
  insert into emp_sal values (1234, '1200,89');
  the trigger is activated and inserts the record in SQL Server:
  Select * from 'emp_sal"@MSODBCSQLSERVER_DG4ODBC_EMGTW_1123_DB;
  EMPNO, SAL
  ----- -------
  1234 1200.89

  It works fine when you post data insert, but as soon as restore you the insert only data Oracle will be cancelled - data will remain as long as the independent transaction dedicated to its SQL Server insert:

  insert into emp_sal values (1384, '1200,89');
  Rollback;
  Select * from emp_sal;
  EMPNO, SAL
  ----- -------
  1234 1200.89

  Select * from 'emp_sal"@MSODBCSQLSERVER_DG4ODBC_EMGTW_1123_DB;
  EMPNO, SAL
  ----- -------
  1234 1200.89
  1384 1200.89

  So I strongly recommend to use the DG4MSQL gateway which is able to participate in distributed transactions and allows validation/restore transactions.

  DG4ODBC lie on OTN (http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html-online check out the "See all" link for your favorite platform), cloud of delivery of software Oracle (https://edelivery.oracle.com/) or "My Oracle Support". My Oracle support welcomes the latest version 11.2.0.3. In My Oracle Support goto patches and updates, then search for 11.2.0.3 data set Patch 10404530patch: 11.2.0.3.0 PATCH SET for ORACLE database SERVER, choose your preferred platform and see the Readme which CD contains the gateway software.

• Oracle and sql server

  Hello
  
  Am a beginner in ODI. I'm frm data source SQL Server and my target table is in Oracle.
  
  I observed the tht some of developed interfaces they apply some functions such as trim, convert etc.
  
  When and why do we need to do this?
  
  For example if the data source type is of type char, fucntions as a garnish are applied. How can we know when to apply this kind of functions?
  
  Any help is appreciated.
  
  Thank you
  ADI

  Hello Adi,

  As a line from bottom of the ETL/ELT concept, when you do any kind of transformation from different source to your data warehouse, you will need to concern about your table DWH metadata structures and date types. If at the time of the map according to the target table manipulations (trim, substr, cast, convert etc.) and more were made to ensure that the target is not data type having violated and data are successfully met.

  How can we know when to apply this kind of functions?

  Yes, you need to know how, where, what and when these functions should be applied by DRAWN from your data source, the target tables and business concepts.

  Makes sense?

  Thank you

• Links of DB Oracle to Sql server

  Hi all
  
  I intend to create DB connection from oracle to sql server 2005.
  
  Please provide the doc to create db connection from oracle to sql server 2005 and also made me know is their any freeware to do the same thing.
  
  Concerning

  It would be useful you might mention what platform works on your Oracle database and word size of the OS (32/64 bit).

  The free solution would be to use the database for ODBC (= Dg4ODBC) gateway and install it on a platform of MS Windows or Linux 64-bit with regard to these 2 platforms that Microsoft offers a free ODBC driver. On all other platforms, you can buy an ODBC drivers appropriate from a 3rd party such as DataDirect provider. I know, some people here on the Forum use FreeTDS but this driver is not a good choice when using it in production.

  Beginning with the documents where you can create a link to database free of charge:

  Please take a look at documents available on the My Oracle Support Portal:
  How to set up DG4ODBC (gateway for ODBC Oracle database) on 64-bit Windows operating systems to connect to Oracle databases Post Install [1266572.1 ID]
  How to set up DG4ODBC (gateway for ODBC Oracle database) on 32-bit Windows to connect to Oracle databases Post Install [466225.1 ID]
  and
  How to set up DG4ODBC (gateway for ODBC Oracle database) on 32-bit Windows to connect to Oracle databases Post Install [466225.1 ID]

  As mentioned for other platforms, you can usually buy a 3rd party ODBC driver and according to licensing costs this 3rd ODBC driver may be more expensive the using commercial product Oracle, MS SQl Server database gateway. It is designed for MS SQl Server connections and much more powerful then DG4ODBC - for example it allows you to call SQL Server stored procedures remotely or to participate in the distributed transaction.
  Documents on the DG4MSQl are also on the support of Oracle Portal.

• Data migration from Oracle to SQL Server

  Hello
  
  I have the Oracle database in one or several table, I also blob data, i.e. images are stored, now I want to move that data to the sql server database, which is the best way to do this?
  
  I would like to test for a migration of the table that contains the image data in the Oracle database and invade the SQL Server table.
  
  How to test for an Oracle table data to SQL Server migration?
  
  But the first thing I want to confirm is that if the Image from Oracle DB to SQL Server DB data are possible? is there something must be supported during the migration?
  
  Thanks in advance.
  
  Kind regards

  Published by: 968331 on October 31, 2012 02:31

  I think that it is supported. The equivalent data type in sql server is IMAGE/varbinary (max)

  See the bottom of the article for the mapping of data types:

• Dblink Oracle to sql server, multiple database on the same server sql under a dblink

  Hi, we managed to set up an Oracle dblink to sql server and retrieve data.

  The user of sql server have been using via dblink has access to multiple databases on the same sql server

  But the question is how in oracle (if possible) prepend you the SQL access to this?

  For example:

  Sqlserver_prod has the user sqlserver_user which seems to be set up as default database sqlserver_db1

  But we have select access to sqlserver_db2

  all work well as sqlserver_user

  Select * from table_fromdb1

  Select * from dbo.table_fromdb1

  Select * from sqlserver_db1.dbo.table_fromdb1

  as does

  Select * from sqlserver_db2.dbo.table_fromdb2

  more in Oracle

  Oracle_db a dblink sqlserver_prod. World connection sqlserver_user

  everything works fine

  Select * from 'table_fromdb1"@sqlserver_prod '.

  Select * from 'dbo '. "table_fromdb1"@sqlserver_prod

  But how to (if possible) access from oracle

  sqlserver_db2.dbo.table_fromdb2

  without having to create a new sqlserver_db2_user referenced in a new dblink

  If oracle for oracle would be

  Select * from remote_oracle_schema.table@remote_oracle_db

  Hello

  You cannot select a table in a different SQL * database server from that to which the gateway instance connects.
  As stated in the documentation-

  Oracle® database gateway

  Installation and Configuration Guide

  11g Release 2 (11.2) for AIX 5 L Based Systems (64-bit), HP - UX

  Itanium, Solaris (SPARC 64-Bit), Linux x 86 operating system,

  and Linux x 86-64

  In the section.

  The example SQL Server multiple databases: Configuration of the modem router

  A separate instance of the gateway that is required for each SQL Server database. Each

  instance needs its own Gateway system ID (SID).

  ==========

  You will need to create a new instance of the gateway for the SQL * Server DB2 as well as a link separate db.

• OBIEE 10 G can connect to a SQL Server database (2005)?

  We have Oracle BI already running. We also have a SQL Server database running. Now, there is requirement that requires to connect to SQL Server and directly send some books SQL on SQL Server and retrieve the result and display it in the answers. I know that the normal procedure should be set ETL to load data from the SQL Server in OBIEE and from there, the report can be built. So I'm not sure it's doable?

  Do the same thing using the online mode. so that you can add a connection pool to the RPD, which is located within the BI server.
