Minimum Hardware and Software Requirements to Install Oracle Real Application Cluster (Oracle RAC 12c)

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)

How to Power On/off Oracle Exadata Machine

<<Back to Exadata Main Page How to Power On/off Oracle Exadata Machine Oracle Exadata machines can be powered on/off either by pressing the power button on front of the server or by logging in to the ILOM interface. Powering on servers using button on front of the server The power on sequence is as follows. 1. Start Rack, including switches Note:- Ensure the switches have had power applied for a few minutes to complete power on configuration before starting Exadata Storage Servers 2.Start Exadata Storage Servers Note:- Ensure all Exadata Storage Servers complete the boot process before starting the database servers 3. Start Database Servers Powering On Servers Remotely using ILOM The ILOM can be accessed using the Web console, the command-line interface (CLI), IPMI, or SNMP. For example, to apply power to server dm01cel01 using IPMI, where dm01cel01-ilom is the host name of the ILOM for the serve...

ORA-46630: keystore cannot be created at the specified location

<<Back to DB Administration Main Page ORA-46630: keystore cannot be created at the specified location CDB011> ADMINISTER KEY MANAGEMENT CREATE KEYSTORE '+DATAC4/CDB01/wallet/' IDENTIFIED BY "xxxxxxx"; ADMINISTER KEY MANAGEMENT CREATE KEYSTORE '+DATAC4/CDB01/wallet/' IDENTIFIED BY "EncTest123" * ERROR at line 1: ORA-46630: keystore cannot be created at the specified location Cause Creating a keystore at a location where there is already a keystore exists Solution To solve the problem, use a different location to create a keystore (use ENCRYPTION_WALLET_LOCATION in sqlnet.ora file to specify the keystore location), or move this ewallet.p12 file to some other location. Note: Oracle does not recommend deleting keystore file (ewallet.p12) that belongs to a database. If you have multiple keystores, you can choose to merge them rather than deleting either of them.

How to Switch Log File from All Instances in RAC

<<Back to Oracle RAC Main Page Switch The Log File of All Instances in Oracle RAC. In many cases you need to switch the logfile of the database. You can switch logfile using alter system switch logfile command but if you want to switch the logfile from all the instances you need to execute the command on all the instances individually and therefore you must login on all the instances. You can avoid this and switch logfile of all instances by just running the below command from any of the instance in RAC database SQL> ALTER SYSTEM SWITCH ALL LOGFILE; System altered.
