Installing Oracle Grid Infrastructure 19.25 on Oracle Linux 9.5 Using ASMLIB 3
From Oracle Linux 8.7 onward, installing Oracle ASM using ASMLIB was challenging due to the need for a kernel downgrade. Recently, Oracle introduced a new version of ASMLIB with enhanced features, enabling the installation of Grid Infrastructure on OEL 8 and 9.
This article will demonstrate how to install Grid Infrastructure 19.25 on Oracle Linux 9.5 using ASMLIB 3.
Prerequisites
Before starting the installation, download the required packages:
- oracleasmlib-3.0.0–13.el9.x86_64.rpm
Download here - oracleasm-support-3.0.0–7.el9.x86_64.rpm
Download here - oracle-database-preinstall-19c-1.0–1.el9.x86_64.rpm
Download here
Pre-Installation Steps
In the following steps, we will prepare the operating system for the installation of Grid Infrastructure.
1.Set the Hostname IP
[root@OL95 ~]# echo "192.168.1.34 OL95">> /etc/hosts2.Create Required Directories for (ORACLE_HOME, ORACLE_BASE and OraInventory)
[root@OL95 ~]# mkdir /grid/19.25 -p
[root@OL95 ~]# mkdir /grid/base -p
[root@OL95 ~]# mkdir /oraInventory3.Install Pre-Installation Package
[root@OL95 ~]# dnf install /source/oracle-database-preinstall-19c-1.0-1.el9.x86_64.rpmThe output was too long, so I summarized it:

Complete!Configure ORACLEASM
Configuring ASMLIB 3 is quite similar to the previous version, and we will demonstrate it below.
1.Initialize ORACLEASM
[root@OL95 ~]# oracleasm init
Mounting ASMlib driver filesystem: Not applicable with kernel 5.15.0
Setting up iofilter map for ASM disks: doneNote: The “Not applicable with kernel 5.15.0” message is expected for OEL 9.
2.Run Configuration Command
[root@OL95 ~]# 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 []: grid
Default group to own the driver interface []: asmadmin
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y
Maximum number of disks that may be used in ASM system [2048]:
Enable iofilter if kernel supports it (y/n) [y]: y
Writing Oracle ASM library driver configuration: done3.Start and Enable the Service
[root@OL95 ~]# systemctl start oracleasm
[root@OL95 ~]# systemctl enable oracleasm
Synchronizing state of oracleasm.service with SysV service script with /usr/lib/systemd/systemd-sysv-install.
Executing: /usr/lib/systemd/systemd-sysv-install enable oracleasm[root@OL95 ~]# systemctl status oracleasm

To use ASMLIB in OEL 9, we must enable the io_uring feature, which is disabled by default.
[root@OL95 ~]# echo "kernel.io_uring_disabled = 0">>/etc/sysctl.conf
[root@OL95 ~]# sysctl –pAfter enabling this feature, we can view its information using the oracleasm status command:
[root@OL95 ~]# oracleasm status
Checking if the oracleasm kernel module is loaded: no (Not required with kernel 5.15.0)
Checking if /dev/oracleasm is mounted: no (Not required with kernel 5.15.0)
Checking which I/O Interface is in use: io_uring (KABI_V3)
Checking if io_uring is enabled: yes
Checking if ASM disks have the correct ownership and permissions: yes
Checking if ASM I/O filter is set up: yes5.Create an ASM Disk
In the next step, we will create a disk using the oracleasm command:
[root@OL95 ~]# oracleasm createdisk asm01 /dev/sdb1
Writing disk header: done
Instantiating disk: done[root@OL95 ~]# oracleasm listdisks
ASM01In contrast to the old version of ASMLIB, version 3 (in OEL 9) does not include the /dev/oracleasm directory:
[root@OL95 ~]# ll /dev/oracleasm
ls: cannot access '/dev/oracleasm': No such file or directoryWe can search for and locate the correct path of this disk(ASM01):
[root@OL95 ~]# find /dev -name 'ASM01'
/dev/disk/by-label/ASM01As you can see, the correct path has been updated to /dev/disk/by-label:
[root@OL95 ~]# ll /dev/disk/by-label/ASM01
lrwxrwxrwx. 1 root root 10 Mar 27 05:27 /dev/disk/by-label/ASM01 -> ../../sdb1Now everything is ready for the installation of Grid Infrastructure. I plan to install it silently.
Install Grid Infrastructure
1.Unzip the Software
[grid@OL95 ~]$ cd /grid/19.25
[grid@OL95 19.25]$ unzip /source/grid_home_19R25_GoldImage.zip2.Run the Installation Script Silently:
[grid@OL95 ~]$cd /grid/19.25
[grid@OL95 19.25]$ ./gridSetup.sh -silent \

-ignorePrereqFailureThe output will look like this:
