Detailed Description and Symptoms
The installation is not able to complete successfully
Investigation
Please check that the user permissions are correctly set up as described in the documentation
Solution
Set up the permissions of a the user such as the ability to log on as a service and has file access to run the programs (the one of the automation engine and the one of the local agent).
If the user is member of a domain, it must belong to the administrator's group of this domain and must have right to act as part of the operating system
And then control that the DB user has got the all necessary permissions (have a look in the installation documentation to check if all the grants are performed correctly)
Also check if the DB client does have the "SQL *Plus" and the "Oracle Database Utility" installed
