Need a custom Oracle Concurrent Program to create Roles and Resp along with the profile options for

We are using Oracle 12c and using multi orgs based environment (Multiple operating units). We are in need of creating a custom program to automate the roles/responsibilities creation. Do you guys think or have any API or have any example programs we can analyze for our usage. Any other ideas or guidance you can provide... on what other options we can use if we want to automate the process (eliminate the manual process of creating the roles/resp/Profile options).

thank you,
