18.3 As easy as 1…2…3

Well, finally it’s here! 18c for on-premise installation so the world can all get stuck into the cool new features of the latest release on their own laptops Smile  At least that is what I’ll be doing!

Naturally as soon as I heard the news, I downloaded the software and got ready to set aside the day for installation and creation of an 18c database. But I didn’t need that long – I didn’t need that long at all. Just a few clicks and a few commands and there it was – my 18c database up and running.

Check out how easy it is with my three videos.

Software Installation

Standard Edition–different optimizer but still cool

One cool technique that the optimizer can employ is the BITMAP CONVERSION TO ROWIDS method to take advantage of B-tree indexes in a means that we would normally associate with a bitmap index. This can be particularly useful with multiple predicates on individually indexed columns because it lets us establish the rows of interest before having to visit the heap blocks.  Here’s an example of that in action, even when the indexes in question are Text indexes.

Enterprise Edition plan

Quick install of prometheus, node_exporter and grafana

This blogpost is a follow up of this blogpost, with the exception that the install method in this blogpost is way easier, it uses an Ansible playbook to do most of the installation.

1. Install git and ansible via EPEL:

# yum -y localinstall https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
# yum -y install ansible git

2. Clone my ‘prometheus_node_exp_grafana_install’ repository:

# git clone https://gitlab.com/FritsHoogland/prometheus_node_exp_grafana_install.git

3. Run the prometheus.yml playbook to install prometheus, node_exporter and grafana:

Enterprise Manager Silent Installation

Introduction

This is another post in my series on silent installations using response files. In previous posts, I covered silent installations for the Grid Infrastructure, RDBMS, post installation configuration steps, and creating the listener and database using response files. In this post, I’ll cover installing Enterprise Manager using a response file.

Creating the Listener and Database in Silent Mode

Introduction

In previous posts, I talked about a customer where I needed to do a silent installation of the Grid Infrastructure and Database, as well as the post installation configuration steps. For that particular customer, I didn’t create an empty database but used RMAN to duplicate the existing database. But what about if you want to create a new listener and database in silent mode as well? That’s what this post covers.

Post GI / RDBMS Installation Configuration Steps

Introduction

This is the third article in a series of blog posts on building a test environment to closely match a Production environment so we could then upgrade the test environment from Oracle Database 12.1 to Oracle Database 12.2. In the first post, I covered performing a silent installation of the grid infrastructure software. In the second post, I followed that by performing a similar silent installation of the RDBMS software. In this post, I’ll be covering the rest of the configuration work for this environment.

Silent Installation of the RDBMS

Introduction

In my last post, I walked you through the silent installation of the Grid Infrastructure software. In this post, we’re moving on to the next stage of the environment build for this customer, doing a silent installation of the RDBMS software.

RDBMS Installation

The silent installation of the RDBMS software is fairly similar to that of the Grid Infrastructure software. You create a response file that contains the responses you would normally provide interactively, and use that with the runInstaller program to perform the installation. The response file I used for that is as follows:
