Construction method:

Method 1	Method 2
1. OS: aix 5300-08	1. OS: aix 5300-08
2. shared storage: concurrent vg --- HACMP manage disks and send volume groups	2. shared storage: RAW (bare device) --- ASM Management
3. Install CRS	3. Install CRS
4. Install ORACLE	4. Install ORACLE

Follow these steps:

The outline process is as follows:

Part 1: Host Configuration

I. Detection System Environment

Ii. Network Configuration

3. users and groups

Iv. Network Parameter Adjustment

VII. install and configure hacmp

Part 3: Install CRS

8. Install CRS

Part 4: Installing oracle software

Constructing RAC in AIX (1) Detection System Environment

Prerequisites for establishing rac environment: ping the device

Because the experiment environment is wireless connection, occasional signal Instability occurs during the process. To avoid this situation, ping the device continuously under win:

>Ping 192.168.8.203-t

>Ping 192.168.8.204-t

>Ping 192.168.8.126-t

Ping Public Network Card IP addresses from two nodes: (refer to network configuration)

[05:50:26 root @ aix203/] #Ping 192.168.8.204

[05:00:23 root @ aix204/] #Ping 192.168.8.203

// The swap partition is generally twice the memory size. It is applicable to both non-absolute and non-absolute values. For example, aix203 only sets the GB swap partition.

// You can use smit mkps to create swap partitions.

// Note: You must place the swap partition on the root volume.

 

View File Systems

[04:21:57 root @ aix203/] #Df-m

[03: 31: 45root @ aix204/] #Df-m

// It is best to set up a file system separately to put it under/u01 (partition under the root volume), about 10 GB

// If/u01 is used as the file system separately, the root does not need to expand much space, but if/u01 is not used as the file system separately, the root must have at least 10 Gb space.

// Temporary file/tmp at least MB of free space (usually about 1 GB)

// If the file system usage exceeds 80%, scale up immediately

How can I configure a shared storage device for two aix servers when setting up an oracle rac environment? What can this shared storage device be?

Shared storage is a storage that can be accessed by two hosts. It generally refers to a disk array.
 
The AIX system cannot be started. aix rac helps

The configuration of another machine should be cloned directly after the machine goes on.
Clone both hdisk0 and hdisk1. If HA exists, re-adjust the HA.
