Installing Oracle 11g R2 using RHEL6 ASM

RHEL6 ASM installation of Oracle 11g R2 tutorial directory:

I. Preparations before installation
Ii. Install the grid infrastructure
3. Install database software
4. Create a listener
5. Create a database instance

If the 1 GB memory requirement is not met, the installation will not be very affected, but a "friendly warning" message will be received before the installation starts.

The general law of the relationship between Swap zone size and physical memory size is as follows:

• If the physical memory is between 1 GB and 2 GB, we recommend that the Swap allocate 1.5 times the physical memory size;
• If the physical memory is between 2 GB and 16 GB, we recommend that the Swap be consistent with the physical memory size;
• If the physical memory is more than 16 GB, it is recommended that the Swap size be 16 GB.

This method is only used for testing. Therefore, only MB of swap space is allocated. Warnings can be ignored.

In Oracle 11gR2, ASM must install Grid Infrastructure separately. In addition, with the installation of database software, the required disk size generally does not exceed 8 GB, therefore, ensure that the available space of the file system in the/u01 directory is more than 8 GB.

The database files will be stored in the ASM mode. Here we use four raw partitions of GB for the active database files + the ASM disk of DATA, one 3g raw partition is used for the ASM disk group in the Flash recovery zone + FRA.

During the installation process, some data is written to the "/tmp" directory. We recommend that the file system space of this directory be smaller than 1 GB.

1.2 configure network parameters

# Cat/etc/sysconfig/network
NETWORKING = yes
NETWORKING_IPV6 = no
HOSTNAME = ora11g.vnimos.org
# Service NetworkManager stop
# Chkconfig NetworkManager off
# Cat/etc/sysconfig/network-scripts/ifcfg-eth0

BOOTPROTO = static
HWADDR = 00: 0C: 29: 32: C3: 9C
IPADDR = 192.168.0.90
NETMASK = 255.255.255.0
ONBOOT = yes
# Cat/etc/hosts
127.0.0.1 localhost. localdomain localhost
