Hardware and Software Requirements To Install Oracle 12c RAC
Note: The requirement in this post is, to install oracle RAC on your Laptop and therefore the requirement in your actual environment could be lightly different and will also depend the business requirement.
In this post I will explain you about minimum hardware as well as software requirements to successfully install and configure oracle RAC using virtual machine on your laptop.
In real environment you need few less things as well there are most OS, Network and storage preparation task is performed by specialists you just need to specify the requirements to them.Hardware Requirements
In real environment you need exactly the amount of servers you need to configure in RAC cluster. eg. you need 2 servers for 2 Node RAC cluster however here we will need 4 Servers as mentioned below
Minimum 2 Servers each with following Configurations <= used for Oracle RAC cluster installation
1 CPU (i5 or i7)
4 GB RAM (more RAM is better)
2 NIC
50 GB HDD minimum per node
1 Server for Storage with following configuration <= In real Environment you don't need it
1 CPU (i5 or i7)
2 GB RAM (more RAM is better)
1 NIC
1 Server for DNS/NTP etc <= In real environment there is already corporate DNS and NTP server configured and you can utilize them
1 CPU (i5 or i7)
2 GB RAM (more RAM is better)
1 NIC
Note:- If you want you can bypass using DNS/NTP and in that case you dont Need 4th Server.
Software Requirements for Oracle RAC Installation
Oracle Linux 7 (Use the latest spin eg. 7.3)
Virtual Box (5.1.14)
Oracle 12c Release 2 (12.2.0.1) Software (64 bit)
IP Requirements for Oracle RAC Installation
7 set of IP addresses (in public IP range) for the purpose as described below
1 Public IP for each node (2 node x 1= 2 IPs)
1 Public IP for each node for VIP (2 node x 1= 2 IPs)
3 IPs for SCAN
2 IPs for Private Interconnect, 1 IP per node
Additionally you need 2 more public IPs to complete the workshop of oracle RAC installation on your Laptop using openfiler as shared storage (1 for storage machine and 1 for DNS machine)
