The "pitfalls" and key points encountered during Oracle RAC installation (I), oraclerac

The "pitfalls" and key points encountered during Oracle RAC installation (I), oraclerac

When using virtual machines to build the RAC environment on a physical machine, many "pitfalls" and key points are encountered.

 

Physical Machine: Intel (R) Core (TM) i7-5600U CPU @ 2.60 GHz, 8 GB memory

Virtual Machine Software: VMware ServerVersion 2.0.2

Database software: Oracle 11.2.0.1, Grid

Virtual Machine Operating System: Oracle Linux 6.2

VM installation plan: the local hard disk is 20 GB, the memory is 2 GB, and the shared disk is 4 in total: 2 VOTE, each 1.2 GB, and 2 data disks, each with 5 GB

 

(1) storage of local and shared disks of virtual machines

I create two RAC nodes and store them in two different folders, for example, D:/rac1 and D:/rac2.

A shared disk cannot be stored in the same location as a VM disk because it can be shared and accessed by two nodes. Therefore, it must be stored separately, for example, D:/sharedisk.

 

(2) Host Name

One step in installing OREL on a VM is to create a host name. Because there are two nodes, the naming rules can be certain, such as rac1.bisal and rac2.bisal.

 

(3) Select a partition scheme

There are several options:

1. Use All Space: Use All Space. Delete all partitions and execute the default installation policy.

2. Replace Existing Linux System (s): Replace the Existing Linux System. Only delete partitions in the Linux File System and execute the default installation policy.

3. Shrink Current System: reduce the existing System. Reduce the size of existing partitions and execute the default installation policy.

4. Use Free Space: Use the remaining Space. Use the remaining space to execute the default installation policy.

5. Create M Layout: Create a Custom Layout.

The default installation policy is:

1. Separate the partitions and mount them to the/boot directory;

2. Create a SWAP partition, which is generally 1.5-2 times of the memory;

3. allocate all the remaining space to/partition;

You can also select 5 to define different partition policies.

 

(4) Select a software group

If you want to install it, You can directly access the graphic interface. Select Desktop here.

 

(5) configure the nic ip Address

Node 1: set two NICs,

Nic 1: the IP address is 192.168.11.200, the Gateway is 192.168.11.1, And the DNS is 192.168.11.200.

Nic 2: the IP address is 10.0.0.200, the Gateway is 10.0.0.1, And the DNS is 10.0.0.200.

Node 2: set two NICs,

Nic 1: the IP address is 192.168.11.210, the Gateway is 192.168.11.1, And the DNS is 192.168.11.210.

Nic 2: the IP address is 10.0.0.210, the Gateway is 10.0.0.1, And the DNS is 10.0.0.210.

After configuration, You can restart the network service: service network restart to make it take effect.
