I want to migrate my mysql databse to oracle. I have followed the migration demo from this url http://www.oracle.com/technetwork/database/migration/connect-step-mysql-1946352.html
but I got this message when try to associate migration repository
sql error on script execution. try deleting repository before creating repository
I am using
Oracle Sql Developer v 4.1.1.19
Oracle express edition 11g releas 2
see the picture bellow what I have tried step by step
step1: Creating a user named migration_repo
step 2: Creating connection named migration_repo using migration_repo user
step3: try to associate migration repository
but after few seconds I got this error message.
Now. how can I solve this? what I have done wrong?
