Application Express 19.1

AskTOM moved to Application Express 19.1 without any major issues last weekend. That in itself is a nice endorsement for APEX, given that the AskTOM application dates back nearly 20 years to 2001, and predates even the existence of APEX.

The only fix that we had to make was that AskTOM uses the static CDN files that Joel Kallman blogged about to make it nice and snappy wherever in the world it is used. The reference to those files have a hard-coded version number so that needed to updated. For AskTOM, we have a plugin that uses some jQuery elements that went pear-shaped when referencing the old version 18 files, but after a quick fix to that reference all was well.

18c database creation on Windows

Hopefully you’ve followed my very simple and easy guide to downloading the 18c database software for Windows. But of course, software on its own is not much use – we need a database! So let’s get cracking and create one. Using the Start menu like I’ve done below, or using the Windows panels, locate the Database Configuration assistant and start it.

After a few seconds the initial screen will ask what you want to do.  Choose “Create Database”.

18c Database installation on Windows

If you’re a Windows enterprise, or you want to run your 18c database on your Windows laptop/desktop for research and education, then there has been some good news this week.  The software is now available to you on the OTN network page.  Here’s a walk through of the software installation process

Head to the standard database downloads page

Accept the license agreement and choose the Windows version to download

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.

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.

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.
