Hi,

I will tell Oracle Automatic Storage Management 18c installation in this post. If you don’t have any information about Automatic Storage Management, please read following articles.

Before Oracle Automatic Storage Management ( ASM ) installation, we need to prepare Oracle ASM disk like following.

ASMLib software is used to format or configure any disk on Linux as an ASM disk. The ASMLib software consists of the following 3 components.

• Open source (GPL) core module package: kmod-oracleasm
• Open source (GPL) utilities package: oracleasm-support
• Closed-source library package: oracleasmlib

We are downloading and installing them with the following yum packages.

Firstly yum install oracleasm like following.

[root@MehmetSalih ~]# yum install oracleasm

[root@MehmetSalih ~]#

And then you should install related yum packages like following.

[root@MehmetSalih ~]# yum install oracleasm-support.x86_64
[root@MehmetSalih ~]# yum install kmod-oracleasm

After Oracle ASM lib packages are installed you need to configure like following.

[root@MehmetSalih ~]# oracleasm configure -i
Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library
driver. The following questions will determine whether the driver is
loaded on boot and what permissions it will have. The current values
will be shown in brackets ('[]'). Hitting <ENTER> without typing an
answer will keep that current value. Ctrl-C will abort.

Default user to own the driver interface []: oracle
Default group to own the driver interface []: oinstall
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y
Writing Oracle ASM library driver configuration: done

Check Oracle ASM status like following.

[root@MehmetSalih ~]# oracleasm status
Checking if ASM is loaded: no
Checking if /dev/oracleasm is mounted: no
[root@MehmetSalih ~]#
[root@MehmetSalih ~]#

İnitialize oracleasm like following

[root@MehmetSalih ~]# oracleasm init
Creating /dev/oracleasm mount point: /dev/oracleasm
Loading module "oracleasm": oracleasm
Configuring "oracleasm" to use device physical block size
Mounting ASMlib driver filesystem: /dev/oracleasm
[root@MehmetSalih ~]#

After seeing Oracleasm software works correctly, the disk is created as follows.

[root@MehmetSalih ~]# oracleasm createdisk DATA /dev/sdb2
Writing disk header: done
Instantiating disk: done
[root@MehmetSalih ~]#

And we can list oracle asmdisk like following.

[root@MehmetSalih ~]# oracleasm listdisks
DATA
[root@MehmetSalih ~]#

The Oracle ASM 18c installation file is downloaded from https://support.oracle.com or https://edelivery.oracle.com and transfered to the server.

The corresponding file is unzip and connect server via vncserver and run the gridSetup.sh file to start the installation like following.

Choose second option to install Standalone Oracle Automatic Storage management installation.

Specify Oracle ASM disk like following. Our Oracle ASM disks are under the /dev/oracleasm/disks/ directory, so type this directory like following.

Choose Redundancy as external like following.

Specify Oracle sys and system passwords like following.

I don’t have Enterprise manager Cloud control so I don’t register it.

Specify operating systems group like following.

Type Oracle base

Type Oracle inventory directory

Click next button

Verification result gives us some warning, we can ignore them.

Installation summary like following.

Execute root.sh in the server with root user like following.

[root@MehmetSalih ~]# /u01/app/oraInventory/orainstRoot.sh
Changing permissions of /u01/app/oraInventory.
