I have 500+ MS ACCESS MDB files, with huge data (400+ GBs) in total. I have a requirement to migrate it to oracle. All MDBs have same table structures.
Any suggestions for best approach will be helpful
I don't know if it is best, but - Oracle SQL Developer (a free GUI tool) offers Migration Workbench which lets you migrate MS Access into Oracle. Here are two pages you'd want to visit:

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.
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:

I have a Oracle 10g database currently in a server.
I will create a web which may have massive requests to get data from the Oracle 10g. So, to prevent degrade the Oracle 10g database and server performance, I would like to setup an Oracle Express 11g to another server, periodically (say 15 minutes) get the data from Oracle 10g to Oracle Express 11g.
Finally the web will just get the data from the new server. And the only loading to the Oracle 10g is the data synchronization. There are just 2 tables in Oracle 10g need to sync.
My question is how can I set up the data synchronization?
For example, can I set up linked server, and set materialized view with refresh period between 2 oracles.
I am new to Oracle, welcome any useful reference materials and idea.
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.
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.
