How To Install Oracle Grid Infrastructure 19c on Linux

In this article, we will install Oracle Grid infrastructure 19c on Linux. Before Oracle Grid installation you need to have OS at first. You may want to read the below article to install Oracle Linux.

Also after grid installation you may want to read the below article to install Oracle RAC 19C on Linux.

How To Install Oracle RAC 19c on Linux

First, we will configure the Disks.

Since I am running a test setup, I will use four disks. Two of these disks will be used for + DATA, the other two for + FRA.

I examine my disks. In the hypervisor environment I am working in, my disks start with SD. It may not start with SD * in your environment. You can fix it according to the situation.

SDB, SDC, SDD and SDE are the disks I added as shared. ASM will work here.

I will prepare the disks. Then we will continue with Oracle ASM.

I am doing the following operation on NODE1. (No action should be taken on NODE2)

We perform these operations for our other disks (sdc, sdd, sde). After our works are finished, there will be an output as follows.

We are restarting the NODE1 and NODE2 servers. In the next step, we will prepare our disks for ASM.

We do the following for NODE1 and NODE2.

Our disks are almost prepared. With oracleasm init, we will enable the kernel and do the stamping process.

We enable the kernel on NODE1 and NODE2 servers.

We will stamp the disks. We only do this on NODE1.

We are checking our disks.

In order for the process that we are doing to appear from node2, we run the following command.

Our disks are ready now. Now we can start the installation. First of all, we will install Grid.

Our files have been copied. Now the setup starts.

Important note: If you are installing on OEL 8.2, Oracle Database 19C currently does not officially support this version. You will need to set the parameter below.

We click on “Configure an Oracle Standalone Cluster” since we will create a new Cluster.

We write our Cluster Name and Scan Name information.

We are adding our second server.

After adding, the two servers need to talk to each other. We will use SSH for this.

At this stage, the system will talk to each other with the user “GRID”. We write the password of our Grid user.

We need to write the network information. We arrange it as follows.

The installation will be on the 4 ASM disks we added. We click on “Use Oracle Flex ASM for storage”.

Now we will add our disks. Since I made the test installation, I will choose “EXTERNAL”.

I will add my DATA1 and DATA2 disks that I prepared for the +DATA.

I set a password for SYS and ASMSNMP users to be used on the grid.

Oracle traditionally runs a script with the root user in the last step of the installation. If we want it to do this process automatically, we can fill in this field. In this way, if a script will be run with the root user during installation, it will be done automatically.

If the cvuqdisk package is seen as missing at this step, you need to do the following actions.

The system status is being checked. Some warnings appeared in my installation. For example, RAM is not enough because a minimum of 12GB ram is recommended. I’m going to click on “IGNORE ALL”.

GRID installation for Oracle Database RAC is complete. In fact, the longest and most challenging is the GRID setup. GRID installation has very sensitive points. For example, if NTP is wrong, there is a problem. Due to the cluster, the clock of both servers must be equal. For this reason, a clean GRID installation is essential.

The next chapter is installing Oracle Database on RAC. Then we will do our tests.
