Hi,
We are in a Windows 7 environment (so I downloaded MySQL Workbench 6.3, MySQL Server 5.7)
I have a large MySQL .sql file which I ran to create the tables, indexes, and other objects.
Now I need to either:
(1) Convert the .sql script to PL/SQL
(2) Migrate the MySQL objects to Oracle 10g
I downloaded SQL Develper ( Version 18.3.0.277) and set up the connections to
(1) our Oracle database
(2) MySQL
so I can view the objects in both
I followed steps here to set up a repository with the appropriate rights and table space:

https://www.oracle.com/technetwork/database/migration/omwb-getstarted-093461.html
When I right click that though to "Create Repository" I receive errors:

So I make sure all objects are deleted and try again with the same results.
I have seen this error mentioned online but I have confirmed the user, MIGRATION, who is associated with Migration_Repository has the correct rights and table space.
Does anyone know how to fix or if there is another option?
I know SQL Developer has a "Copy to Oracle" option which works -- but I also need to copy over indexes.
Thank you for your help and Happy Thanksgiving
(I am grateful for this community - thank you!)
