• Migration from SQL Server to Oracle database

  I have 2 questions:
  
  1. we intend to convert our sql server databases oracle OLTP databases. I tried to use SQL Developer to migrate a database of small sql server to oracle (size 5 GB) database. It was fine. When I tried to migrate to a different database (size 90G), it takes too much time. The problem with sql developer is I can not pick and choose tables. 250 paintings, I need to migrate tables abt 80 (the size will be abt 50 G). What is everyone can share their experiences, as appropriate, converting databases of size average sql server for oracle databases? other options?
  
  2. I intend to convert the sql server ddl to oracle ddl. I have tested bcp out and use sql loader to import the data. Right now I am manually creating the oracle tables sql server tables. I use http://download.oracle.com/docs/cd/E11882_01/gateways.112/e12069/apa.htm#BABCIIDI to convert the code. Are there other ways better to convert sql DDL DDL Oracle Server?
  
  Thanks in advance

  DDLS must be converted manually. Oracle is not SQL-Server.

  If for example, you have the option of partitioning, you should consider using the partitioning index and when it is possible. Not all tables must be hash tables. Do postpone you creation of segment or not? What type of tablespace? Set yourself free percentages and allows you to manage when the data block is on the free list and how much is reserved in the block of data to update rows in this block?

  There are many considerations to be taken with regard to the physical database design.

  Using BCP and SQL * Loader sound good. SQL * Loader is fast and scalable - use it to load up to 3.6 million lines every 60 seconds. Direct and parallel charges will give the best performance in this regard (assuming that the underlying table structure and use supports this approach).

• Problem with the migration of key primary and foreign from SQL Server to Oracle

  Hi people, I use SQL Developer to migrate Oracle to a SQL database, and I'm stuck with a few questions:
  
  So far, the worst of them is the fact that I can not migrate the PKs and FKs. After having successfully captured the model DB in SQL Server and Oracle conversion, when the tool generates scripts, all ALTER TABLE queries that add pharmacokinetics and the FKs have their columns duplicate targets.
  
  for example: when I'm trying to migrate a simple table that contains an Id (PK) and the columns name, the tool generates the following scripts:
  
  
  PROMPT create Table TestTable...
  CREATE TABLE TestTable)
  ID NUMBER (10,0) NOT NULL,
  Name VARCHAR2 NOT NULL
  );
  
  The PROMPT create constraint primary key on the table TestTable PK_TestTable...
  ALTER TABLE TestTable
  ADD CONSTRAINT PK_TestTable PRIMARY KEY
  (
  ID,
  ID
  )
  ENABLE
  
  
  Regarding the FKs, the tool duplicates the columns thus:
  
  ALTER TABLE SomeTable
  ADD CONSTRAINT FK_SomeTable_SomeTable2 FOREIGN KEY
  (
  SomeTable2Id,
  SomeTable2Id
  )
  REFERENCES SomeTable2
  (
  ID,
  ID
  )
  ENABLE
  ;
  
  Does anyone have an idea on how to solve these problems? I would be very grateful for answers!

  Hi Fernando,

  I was unable to reproduce this problem. My primary / foreign keys when defined using unique columns.

  The PROMPT create constraint primary key on the suppliers table PK_Suppliers...
  ALTER TABLE suppliers
  ADD CONSTRAINT PK_Suppliers PRIMARY KEY
  (
  Vendor No.
  )
  ENABLE
  ;

  I tried a few things like
  capturing twice and rename the two models of the same
  Rename the converted templates
  but without success.
  I think that this problem occurs is in the capture phase or convert.

  (1) you perform the capture online or offline?
  (2) can provide you a DDL together for one of these tables and the indexes to see if I can reproduce?
  (3) made of capture or convert fail or be again at any stage?

  I all else fails I would attempt a capture and convert again using a new repository (create a new schema in Oracle and associate him the migration repository).

• Migration from SQL Server to Oracle during 11.1.2.4 upgrade

  Hi all

  To further expand on the title, wanted to check if it is possible to migrate from SQL Server to Oracle, while improving 11.1.2.1 to 11.1.2.4 on brand-new material. There is a change in all the components (s/w, h/w, RDBMS) so I wanted to run this generic statement by the forum to see what the experts think.

  Where in the equation can count us on LCM?

  I know that John Goodwin had already answered a few questions on the same subject for previous versions, but as 11.1.2.4 is a different game... I would be grateful if someone could share their thoughts.

  Thank you!

  If you are installed on hardware costs and migration then it should be independent of the RDBMS. Not to say there is no problems with passing of 11.1.2.1 to 11.1.2.4 (if you use planning, for example, business rules-> Calc Manager) but they certainly should not be linked to the fact you've changed the underlying database.

• Error of date when migrating to SQL Server to Oracle

  Hi all
  
  I'm the database migration SQL Server to Oracle.
  
  But the tool I use is not secret the date type GBA, so I'm stuck with tables that have particular date types.
  
  For example: the 'DATECAPTURED' column in the 'SIGNATURE' table in the SQL Server database has values:
  
  15-02-2013 10:03:48.387
  15-02-2013 10:01:05.930
  15-02-2013 09:59:07.197
  15-02-2013 09:50:15.797
  15-02-2013 09:39:15.557
  15-02-2013 09:37:12.643
  
  Why oracle can be able to accept this type of date format? :( I thought he is more intelligent than SQLserver :)
  
  My solution is to change any date to varchar2 (30).
  
  More bright ideas? while I cannot change data types?

  It's just that I have a lot to learn in a fastrack way, I am a very busy person :(

  Well, just a piece of advice. If you read the watch (and wait) documentation for the responses on the web and on various forums and try to do all the work, you are probably going to stay busy!

  in any case, I'll try another tool like sqldeveloper migration. For now, I have many things to research so I'd settle for the same time, workaround. New test is required for the tool.

  Good luck!

  I was taking just opportunities here if someone met the same problem as mine ;)

  It was not a problem of IMO, but was ignorance. People here know any Timestamp data type for SOME time I think and how, because they read the docs!

• How to migrate from SQL server to oracle 11g

  Hello
  I have a lot of tables in sql server, and I want to connect them in oracle

  Welcome to the forum,

  Hello
  To create a link Oracle with SQL Server follow these steps:
  1. install Oracle ODBC drivers on the server (your Oracle database local) who will have access to the remote SQL Server database by using the database link.

  2. configuration of the ODBC connection on the local Oracle using the Windows ODBC Data Source Administrator database

  3 test pilots to verify ODBC connectivity is made to the SQL Server database.

  4. make sure that your global_names parameter is set to False.

  5. configure Oracle heterogeneous services by creating an initodbc.ora file in the Oracle database.

  7 change the Listener.ora file.

  SID_NAME is the DSN for the remote database.
  ORACLE_HOME is the real path to the file at Oracle.
  PROGRAM says Oracle heterogeneous services.

  SID_LIST_LISTENER =
  (SID_LIST =
  (SID_DESC =
  (SID_NAME = Cas30C) - enter the DSN on this line
  (ORACLE_HOME = c:\oracle10gdb)--Inscrivez your Oracle home
  (Program = hsodbc)) )

  8. change the Tnsnames.ora file. It's accessed by users Oracle database installation connect for ODBC drivers

  (DESCRIPTION =
  (ADDRESS_LIST =
  (Address = (PROTOCOL = TCP)
  (HOST =
  -(X server)
  (PORT = 1521))) -Enter the port on which the server x installing Oracle
  -is listening
  (CONNECT_DATA = (SID = Cas30c)) - enter the name of the DSN
  (HS = OK)-enter this value. He indicates to Oracle to use transfer services
  )

  9 recharge the listener on a local Oracle database

  10. create a link of database on the local Oracle installation that accesses the heterogeneous connection, which, in turn, connect to SQL Server.

  11 execute SQL Select Server from the Oracle installation using the database link

• data replication with ODI between SQL SERVER and ORACLE

  Hello world
  First of all, I want to migrate database SQL SERVER and ORACLE DB tables.
  And then make online (synchronous) replication from SQL SERVER to ORACLE using ODI.
  
  I have not used before ODI.
  How to use the ODI for this?

  1. create a master repository and connect to the "topology Manager.
  2. in the topology Manager, you must configure the following
  2.1 create a data server for the Oracle under Oracle database in the physical connection
  2.2. create a database for the SQL Server database server in SQL Server in the physical connection. To do this, the jdbc for sql server driver.
  2.3 implement the logical connection and frame
  2.4 create a workrepository in the topology manager repositories tab
  3. connect to the designer and follow these steps
  3.1 create a template for the SQL Server source and reverse (import) the datastores (tables) to the model.
  3.2 the value of the model for the target of the Oracle
  3.3 create a (mapping) interface, under the table in schema define the source and then add it to the target and bind
  3.3 on the flow tab, you must set the Modules (KMs) of knowledge to perform the load. You must have imported the KMs before creating the interface.
  3.4 in IKM put 'create table traget' to 'yes '.
  4 run the interface to load data from SQL to Oracle Server

  Thank you

  If you notice the first column in the two outputs. It is sorted in sql server and no oracle.
  
  Why he behaves differently in oracle? Is there a way I can fix this problem in oracle?
  
  Thank you
  Jigs

  It is NOT a behavior "differently" in Oracle; you did not specify just an order that you expect of your results, so you'll get output in what order the fantasies of the database showing (ie. no guaranteed order). It is an artifact of the way the database chooses to collect the data and databases (or same sets of data within the same database) can and will most likely behave differently.

  Same SQL Server will not be guaranteed to always get your data in an orderly manner if you exclude the order by clause, even if you think that there always display the data in an orderly manner.

  Your solution is to add an order by clause, in the TWO databases, to force the order of the data output.

• Planning for SQL server and Oracle db

  Hi friends

  We intend to improve our environment Hyperion of 9.3.3 to 11.1.2.2. and we will go from SQL server as our RDBMS Oracle.

  If we change DBMS, do we have to rebuild the total application or is there an easy way to migrate from sql server to Oracle

  Please suggest

  Thank you

  Upgrade the application to 11.1.2.2 while remaining on the SQL Server, then use LCM to export the application, remove the application, update the data source to point to Oracle, use LCM to import.

  See you soon

• Hyperion at level 11.1.1.3 to Hyperion 11.1.2.3 with change of database SQL server and Oracle DB

  I am upgrading the Hyperion 11.1.1.3 environment in new infrastructure which include (HFM, Shared service, FDM and Hyperion reporting). The 11.1.1.3 had SQL Server repository, now we are making everything on the Oracle database repository. Can I directly use the LCM to migrate all of the artifacts of 11.1.1.3 11.1.2.3. Can someone advise how best to do the migration. Y at - it something I should look. Something that fail often I should look.

  There are a number of ways to achieve what you're trying to do and it may depend on the number of products/applications and the complexity of the environment.

  There are also ways to migrate to a SQL database to Oracle with different success rates depending on what is involved.

• How only migrate data between SQL Server 2008 Oracle 11?

  According to our requirement, we only have to migrate data from a SQL Server database to an existence
  Oracle database user.
  (1) I tried to do with the wizard of Migration SQL Developer 3.0.04, but find a problem.
  My SQL Server database name is SCDS41P2 and my Oracle database user name is CDS41P2;
  When I used SQL Developer move offline data by the Migration Wizard, I found all the oracle user
  name in movedata files who obtained by running the Migration Wizard
  is dbo_SCDS41P2. If the Oracle user name is not the same as my Oracle username existed.
  the data cannot be moved to my user Oracle existed when I run oracle_ctl.bat in the command line window.
  So I had to change the Oracle username in all the movedata files, but it is difficult to change because there are a lot of tables in
  databases. So could you please tell me how to get the movedata files which is the name of user oracle in them my
  WHEREAS Oracle user name?
  
  (2) I also tried to use the "copy to Oracle" to copy the data to SQL Server database tables
  the user database was Oracle. When you click on 'copy to Oracle', I selected the option 'Include data' and 'replace '.
  But I found some tables cannot be copied, the error info is as below:
  SPSSCMOR_CONTROLTABLE table failed. Message: ORA-00955: name is already used by an existing object
  
  Could you please tell me how to deal with this kind of mistake?
  
  Thank you!

  Hello
  After following with development the following should work too-

  1 use the migration option to capture and convert the SQL * database server
  2. go in SQL * Developer and remove the converted model.
  3. click on the captured model and choose 'convert '.
  4. click Next and you should get a screen with 2 options - "Data Type Mapping" and "Object Naming.
  5. choose "Object Naming" and scroll down the list until you see the name of the user who will be transformed. For example, in my test, I got the names scott_test and dbo_test - where the owners are 'scott' and 'dba' and 'test' was the name of the database.
  6. change the name of oner_database to just owner - scott_test to scott
  7 complete the conversion process and the owners must be created without the name of the database.
  8. you should now be able to generate the SQL * scripts of charger with only the name of the owner in the CTL files.

  Please try this and let us know if it works for you.

  Kind regards

• Mapping of Data Type from SQL Server to Oracle

  I use Oracle 12 c with heterogeneous services connects to SQL server DB. Some of the columns in the SB of SQL Server are defined as 'nvarchar (max). These come to Oracle as columns of type "long". I would like that these are 'varchar2' types in Oracle, so I do not have any restrictions related to the fields of type "long" when using. I can create a view in SQL Server to convert the data type IE. nvarchar (100). What is the highest value that I can use to make the data to display in Oracle as a varchar? BTW, I tried nvarchar (4000), but which showed any longer. I tried nvarchar (1000) and who showed as a varchar.

  The maximum value for an nvarchar2 in Oracle is 2000. Mapping - If the remote column is mapped to an Oracle varchar/nvarchar - depends on the type of data returned by the ODBC driver. When the driver returns SQL_Varchar, then the maximum precision is 4000 and when it will map it to SQL_WVarchar then it's 2000.

  As your Oracle database uses AL32UTF8 as set of characters that the maps to the Oracle long as your SQL Server nvarchar content is stored using characters UCS2 nvarchar (max), you will get the value that is covered by the database Oracle UTF8 character set. So it shouldn't really matter if the returned string is mapped to an Oracle, varchar or nvarchar.
