Oracle Resource Manager is an internal Oracle solution that allows you only to prioritize  between databases users (rather than allocate resources). It starts prioritizing the CPU consumption only, of specific transactions, once your machine hits the 100% CPU.In most databases, being in 100% is unsafe.

In addition, in most databases, Heavy IO consumers (such as reports) doesn’t take your machine to the 100% CPU utilization and therefore – when it comes to I/O bottlenecks, ORM is useless.

ORM gives you the ability to allocate your resources based on databases users only while most application nowadays identifies themselves to the database as a single user to the database.
Allocating resources to a specific databases users under these circumstances, is a matter of 15-20 clicks (or massive scripting) in ORM, while only 1 mouse click in MoreVRP. In addition ORM doesn’t let you do that in real-time to an already running transaction.
 
Unlike ORM, MoreVRP allows to:

• Resource Bandwidth Allocation (rather then just prioritization)
• Working below 100% CPU
• Stabilizing your system while never letting it get to the 100% utilization.
• Manage both your CPU & IO per transaction.
• Real-Time Monitoring
• Affecting already running transaction in real-time. (Ad hoc and rule based)
• Easy to Use (Mouse clicking rather than scripting)
• Allocated resources based on your business characteristics (transaction, time
• of the day, Applicative module, program, PC name…) and not only by database users.
• Low Footprint
• Manage QoS of users on the same databases, and between several databases.
• System processes Management & Control
• Recommendations, SLA & QoS reports
