How to Build 19c RAC - 2 of 4 - Installing Grid Infrastructure

  • by

Since we have well prepared two database servers for the RAC database in the previous post, the only job we should do in this post is to install Grid infrastructure.

There're two parts in this post.

  1. Grid Installation
  2. Create Disk Group DATA

Grid Installation

If you see the following error dialog, it may be because of the newer OpenSSH 8.x.

INS-06006 Passwordless SSH connectivity not set up between the following node(s)

You should fix scp for INS-06006 problem during installation.

For accessing the shared storage, those ASM disks should belong to ASM administrator (OSASM) group, which is asmadmin in this case. I have talked about it in persistent naming of ASM disks.

An item failed to pass Oracle Cluster Verification Utility (CLUVFY).

Let's see what just happened.

As we can see, it's a clock synchronization check. Since we use chrony instead of NTP to synchronize time, we are going to skip the error.

By the way, I also used chrony in Grid infrastructure 18c installation on OEL 7, but I didn't see any error. Is it a bug of grid infra 19.3 on OEL 8.1? I heard about the bug has been fixed since 12.2.

Grid infrastructure has been installed.

Create Disk Group DATA

We have created OCR and MGMT two disk groups, but we have not created a disk group for databases yet. Let's do it now by ASM Configuration Assistant (ASMCA).

Be careful, NORMAL redundancy will cut the lift of disk space into a half. I really don't think it's a good idea to build any kind of redundancy in ASM according to modern technology of storage devices. We should let the storage to play its role.

Sometimes, cutting the lift of disk space into a half could be very serious, because there's no direct way to change a disk group from NORMAL back to EXTERNAL. For example, we expected one high-end storage to serve databases for at least 6 years, because of the factor of NORMAL redundancy, we can only use it for 3 years.

A disk group DATA has been created.

Next, we can safely install Oracle database 19c software.
