Node and Instance in Oracle RAC

BalajidbaDec 10 2019 — edited Mar 5 2020

Hi ,

Can someone explain the below concept of instance and node in Oracle RAC with example?

An instance can access one and only one database. With Oracle RAC, there are multiple instances for one database. Each instance runs on a separate database server, called a node in the cluster

Regards,

Balaji

If you install Virtualbox on your MacBook, you can use this appliance to get an Oracle database:

Mac was supported years ago with 10g. Think that even RAC support was planned. (https://docs.oracle.com/cd/B19306_01/install.102/b25286.pdf)
As I heard things went south between Oracle and Apple, and the support for Mac was discontinued.

There are no Mac version for Oracle Databases, but as cormaco mentioned you can easily use VirtualBox to have a VM with Linux (you can use Oracle Linux) and install Oracle 18c XE on it.
Or you can use the VM he already pointed, it has Oracle 19c pre installed, and you can add 18c XE if you need (if you just want to test or do some Proof of Concept, then using the 19c should be OK, if you want to use it for commercial / production then you need either a license or to use the free XE edition).
