I have migrated the SQL Server database to Oracle using SQL DEVELOPER, I have followed all steps for the migration:
The migration passed successfully, but I cannot find the tables in the database.
I only found those tables(auto-generated on any Oracle migration):
Can the tables be located in another place? how can I find them?

We have databases like oracle, sql server, postgres and looking to synch the data like full/delta load into one database. Can you suggest some tool to do this.
Yes, SSMA can do that.
Migration Sources allowed are:
SQL Server Migration Assistant for Access
SQL Server Migration Assistant for DB2
SQL Server Migration Assistant for MySQL
SQL Server Migration Assistant for Oracle
SQL Server Migration Assistant for SAP ASE
But the destination will always be SQL Server.
Once your databases are all SQL Server I suggest you to merge them all together dividing them by schema.
Is a very primitive way to work but is the only I know.
I have an SQL Server installed on a local Windows 10 machine - I'm using Microsoft SQL Server Management Studio to interact with it.
I also have a DB2 database hosted on an IBM i machine and I've created a Linked Server in SQL Server Management Studio to represent it. I can connect to the Linked Server and can query/pull data from it successfully.
I'm trying to copy particular tables from the Linked Server and insert them into a Database/Schema in the SQL Server - I can do this successfully but unfortunately, it appears that in the process of copying the table over, none of the constraints (particularly in my case, the key constraints) are maintained.
Is there a simple way to copy over tables from a Linked Server to SQL Server (in SQL Server Management Studio) while maintaining key constraints?
The following query is an example of what I'm using to copy the tables over (one-by-one):
SELECT *
INTO SQLSCHEMA.SQLTABLE
FROM LINKSERVER.LINKDATABASE.LINKSCHEMA.LINKTABLE
The easiest way is to use proper tool for it like SSMA:
Microsoft SQL Server Migration Assistant (SSMA) is a tool designed to automate database migration to SQL Server from Microsoft Access, DB2, MySQL, Oracle, and SAP ASE.
Migrating DB2 Databases to SQL Server (DB2ToSQL)
SQL Server Migration Assistant (SSMA) for DB2 is a comprehensive environment that helps you quickly migrate DB2 databases to SQL Server or Azure SQL DB. By using SSMA for DB2, you can review database objects and data, assess databases for migration, migrate database objects to SQL Server or Azure SQL DB, and then migrate data to SQL Server or Azure SQL DB. Note that you cannot migrate SYS and SYSTEM DB2 schemas.
I have created my database and tables in a SQL Server Express database. And now I migrated the database tables to Oracle with Entity Framework. But my tables are empty in Oracle. How can I move my data to Oracle?
Use SSIS interface from MS-SQL (Sql Server Integration Service).
I have used to move content from MSSQL to MySQL you should use the correct odbc driver.
For express edition, You can use Linked Servers to establish connection between SQL Server and Oracle. In this way, you should insert the records by creating queries for per table.

I have a project with a SQL Server Express database and Entity Framework migrations. But I need to migrate my SQL Server Express database to Oracle. But Oracle database has existing tables. How can I migrate to Oracle?
If I set Oracle connection strings and run a command update-database in package manager console, will existing database tables be deleted? Or what is the best way?
Funny question does the Oracle db tables have data stored?
I recently did a Oracle to SQL Server 2008 R2 Migration. The PL/SQL stored procedures were converted to T/SQL by SSMA. The converted T/SQL has many references to the sysdb database, for instance sysdb.ssma_oracle.db_check_init_package
I then exported the SQL Server 2008 R2 database, and imported it to SQL Server 2012. However I forgot to copy the sysdb database. What is the easiest way of creating the sysdb database?
Thank you!
Just install SSMA for Oracle 5.2 Extension Pack.exe (downloadable from Microsoft) on the computer with the SQL Server database (tell it to ignore the fact that Oracle is not installed on the computer) and it will create the sysdb database for you, and also the Extended Stored Procedures that it needs.
