# What is Logical Partition LPAR in Oracle

Oracle, as we all know, is the most popular database. Some of the terminologies cause a little bit confusing for developers.

## I am just explaining about LPAR Oracle:

A [logical partition](https://srinimf.com/2013/02/10/mainframe-lpar-and-prsm/) (LPAR) is the division of a computer’s processor s, memory, and storage into multiple sets of resources so that each set of resources can be operated independently with its own operating system instance and application s.

Logical partitioning was first studied by IBM in 1976 and later introduced by Amdahl and then IBM. Hitachi and Sun Microsystems also use forms of logical partitioning.

Today, both IBM’s S/390 (now z/900 Series) and AS/400 products support logical partitioning.
