What is soft partitioning?

Soft Partitioning: This is a flexible way of managing data processing resources since the CPU capacity can be changed fairly easily, as additional resource is needed.

What is hard partitioning?

Hard partitioning means binding vCPUs to physical CPU threads or cores, and preventing these vCPUs from being scheduled on physical CPUs – threads or cores other than the ones specified.

What are the different types of partitions in Oracle?

What is Oracle KVM?

KVM provides a set of modules that enable you to use the Oracle Linux kernel as a hypervisor to run virtual machines. KVM is built into the Oracle Linux Unbreakable Enterprise Kernel (UEK) by default.

What is IBM LPAR?

An LPAR is a subset of the processor hardware that is defined to support an operating system. An LPAR contains resources (processors, memory, and input/output devices) and operates as an independent system.

What is isolation in virtualization?

Isolation – Virtualization allows providing guests—whether they are operating systems, applications, or other entities—with a completely separate environment, in which they are executed. The guest program performs its activity by interacting with an abstraction layer, which provides access to the underlying resources.

How many types of partitions are there in SQL?

There are two types of Partitioning in SQL Server: Vertical Partitioning. Horizontal partitioning.

What is hash partition in Oracle?

Hash partitioning maps data to partitions based on a hashing algorithm that Oracle applies to the partitioning key that you identify. The hashing algorithm evenly distributes rows among partitions, giving partitions approximately the same size.

What is KVM and OVM?

Oracle is phasing out Oracle Virtual Machine (OVM) in favor of Oracle Linux Kernel-based Virtual Machine (KVM) End of Premier Support for OVM. Many Oracle customers adopted Oracle Virtual Machine (OVM) as their virtualization platform taking advantage of hard partitioning capabilities of OVM.
