While configuring Oracle SQL Developer 19.1 and Oracle 18c for data Mining I am facing a small difficulty which stopping me from making further progress.
After adding dmuser(I have set dmuser correctly as per instructions in manual) and right click to create project. I will be getting below screen to log in with SYS user
[This database does not have the Data Miner repository installed.
Would you like to install the repository?
You will be prompted to authenticate as a database administrator to perform this task.]
When I click on Yes then It will ask for keying SYS password. When I provide correct password for SYS user
ORA-01017: invalid username/password; logon denied
I am not sure in spite of giving correct user why it is showing invalid username. I need some guidance on this how to proceed or if I am making any mistake.
