There is one scenario where in our target is to migrate oracle database to Azure SQL DB.
Currently I am evaluating multiple options to migrate the existing Oracle Db to the Azure SQL DB, for the same reason I could not decide how to handle this situation where in the source DB i.e. Oracle is having transaction data which is a kind of incremental load.
Should this can be handled with mere replication of DB? or performing some data migration steps would help me ? Here i can think of earlier approach as easier approach where in i need not to worry about the transaction updates happening inside the data.
Considering this which utility i should use to perform this kind of activity?
You can replicate your Oracle database to Azure using Oracle Golden Gate as a way to migrate your Oracle database to Azure SQL. Striim seems to be another good tools to move your database to Azure SQL.
I think you may use the SQL Server Migration Assistant (SSMA) for Oracle.
SQL Server Migration Assistant (SSMA) for Oracle consists of a client application that you use to perform a migration from Oracle to SQL Server and Azure SQL DB. It also contains an extension pack that supports data migration and the use of Oracle system functions in your migrated databases.
SSMA can converts the transaction processing:

Hope this helps!

Data was sent to our company with PostgreSQL, but we are prohibited to use the tools of PostgreSQL , permitted the use of only Oracle.
How to migrate data from PostgreSQL to Oracle without using a third party application(they are also prohibited)? You can only use the tools of Oracle.
I found this article https://support.oracle.com/knowledge/Oracle%20Database%20Products/2220826_1.html but we don't have Support Identifier
We have one .sql file. It weighs 8 Gigabytes.
It looks like you have so many impediments in your company. Regarding Oracle's SQL Developer Migration Workbench, unfortunately it does not support the migration of PostgreSQL databases. However, the following 3rd-party software tools are available and may assist in migration, but I am afraid you cannot use them as you said that those products are forbidden:

Other options will only move the data from your Postgresql database to Oracle database, it means that you must have the DDLs of the tables before to run the import:
To move data only, you can generate a flat file of the the
PostgreSQL data and use Oracle SQL*Loader.
Another option to migrate data only is to use Oracle Database
Gateway for ODBC which requires an ODBC driver to connect to the
PostreSQL database, and copy each table over the network using
sqlplus "COPY" or "CREATE TABLE AS SELECT" commands via oracle
database link.
Also, Oracle has discussion forum for migrating non-oracle databases to Oracle.
http://www.oracle.com/technetwork/database/migration/third-party-093040.html
But, if you have only a sql file, you should look at it to see whether you have both DDLs ( create tables and indexes, etc ) and the data itself as insert statements. If so, you need to split it and treat the DDLs to convert the original data types to Oracle datatypes.
Is there any way to move the data from Oracle to Azure SQL Databases? We need to do 1 time migrations our database sizes are not so huge in size can ADF be the best option here, can we directly restore on-premise oracle database to azure sql databases?
You can use SQL Server Migration Assistant (SSMA) for Oracle to migrate your Oracle data or database to Azure SQL database.
SQL Server Migration Assistant (SSMA) for Oracle is a comprehensive environment that helps you quickly migrate Oracle databases to SQL Server, Azure SQL DB, or Azure SQL Data Warehouse. By using SSMA for Oracle, you can review database objects and data, assess databases for migration, migrate database objects to SQL Server, Azure SQL DB, or Azure SQL Data Warehouse, and then migrate data to SQL Server, Azure SQL DB, or Azure SQL Data Warehouse
Please see this Azure tutorial: Migrating Oracle Databases to SQL Server(OracleToSQL). Just need to follow the tutorial and migrate your Oracle data to Azrue SQL database.
You also can reference tutorial isalgueiro provide for you: Migrate Oracle to Azure SQL Database.
Hope this helps.
We have two divisions in our company, one uses E1 on Oracle 11g the other uses SAP on Oracle 11g.
We also have a SQL Server system we use to data warehouse information once a night from both system to run our report server against.
The question I have is for pooled tables in SAP, such as A016, how would I get that information out of SAP?
Currently we have SSIS's setup with a linked server to the two Oracle servers which pull the data we need I just don't have the knowledge of SAP to find the Pooled tables.
if I can't pull the pooled tables because they don't physically exist is there a tool I can use in SAP to find out what tables the pooled table is getting it's information from? This way I can rebuild that table in SQL using a open query and some fun Joins.
Thanks
You have to access those tables using the application server. They can't be accessed directly from the database.
You'll probably want to write an ABAP program to extract the data you need go from there.
I have a Microsoft SQL Server database(tables, relationships and data).
But now I want an exact same copy of this database in Oracle.
I was thinking there may be some sort of a tool or converter that could generate Oracle sql scripts that I could run to create and populate my new Oracle database.
Is this kind of thing possible?
And how can I achieve this ?
Your best bet is to use a DB modelling tool which can reverse engineer your SQL Server database and then generate a script to recreate it in Oracle.
DB Designer Fork can do this for you and is Open Source.
Are there any tools that I can use to migrate my Oracle database to SQL Server 2008? If not what are other choices for this type of migration?
With migration I need to move only tables (with all indexes and constraints) and data. There are no any functions, views or stored procedures.
See e.g.
Microsoft SQL Server Migration Assistant (SSMA) for Oracle is a free tool for migrating Oracle databases to Microsoft SQL Server. SSMA for Oracle converts Oracle database objects (including stored procedures) to SQL Server database objects, loads those objects into SQL Server, migrates data from Oracle to SQL Server, and then validates the migration of code and data.
