Currently I'm learning how to use Oracle's SQL
And I ran into a problem which I cannot find the answer to,
I am using the SQL Developer provided by Oracle 12c and am currently using the Migration Wizard that comes with it
While trying to migrate data from MS SQL 2008 to Oracle 12c, the migration wizard tells me that the migration is complete. When I look at the repository, the tables are all moved and converted, but none of the data have been populated into the tables. I have been trying to look for migration logs, but I have not been able to find the location for the logs and I was wondering if anyone has ran into this problem before and has a solution for it.
Just create new connection oracle connection, call it with name of migrated DB, user = , password = .
E.g. you migrate test_1 DB. After migration, create connection with name test_1, user = test_1, password = test_1.

We are migrating our database from SQL Server to Oracle using the SQL developer tool. While migration, the schema name in SQL Server is "schmdw". This schema is used in our datawarehouse or OLAP database AdvworksDW. After migration we were expecting the schema/user name in oracle will be schmdw. But it is coming as schmdw_AdvworksDW i.e. schemaname_databasename. How can we get rid of this and get the schema/user name in Oracle as schmdw only? Can anyone help me in this regard?
In Oracle, there's no supported way to rename a schema/user. The best solution for you is to create another user, SCHMDW in your case, and give it grants on all objects of the SCHMDW_ADVWORKSDW plus synonyms. Have a look at the second comment on this post, it gives a pl/sql script to automate that.
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.
I can connect to my 12c Oracle database using Oracle's Sql Developer and see my schema, but when I connect via SSMA I can't. I see a bunch of other schemas in SSMA, which I assume came with Oracle because I've only created two users on the box and I don't see either of them in SSMA. I'm connecting using the System account, so I don't think it would be a permissions issue. As you might be able to tell I don't know much about Oracle. Where could my schema be hiding?
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!
I am trying to migrate sonar's H2(default database) to oracle database. For this I have edited sonar.properties file. I commented sonar URL and uncommented oracle URL(I made jdbc connection with oracle database and pasted that URL in sonar.properties). I have also changed sonar usename and password in sonar.properties. When I start sonar it gives me error and ask me to create tables in oracle database and even if I create tables in oracle it still ask me to create such more tables.
Do I need to make some more configuration/file changes? Am I missing something?
Any help would be highly appreciated.
