How to Fix ORA-65096: Invalid User or Role Name Error
To fix the ORA-65096 error, you need to ensure that the username or role name you are trying to create is valid according to Oracle's naming rules. Here are the steps you can follow:

Check if the username or role name is a reserved word or system identifier

Use valid characters and limit the name length
