Infrastructure at your Service
A few things have changed about the Autonomous Data Warehouse Cloud service recently. And I’ve found the communication not so clear, so here is a short post about what I had to do to start the service again. The service has always been on the OCI data centers but was managed with the classic management interface. It has been recently migrated to the new interface: Note that ADWC here is the name I’ve given for…
In the Oracle Cloud PaaS you have a marketplace where you can choose your service. Some are packaged from Bitnami and available on multiple OS. My first idea is that in PaaS you do not care about the OS. But Oracle Cloud has this very nice feature where you still have full access to the OS, as root, even in PaaS. Then, you choose the Linux distribution of your preference. Except if performance is different….
In the previous post about the Autonomous Data Warehouse Service, I’ve run queries though the Machine Learning Notebooks. But you obviously want to connect to it from your premises, with SQL*Net.
You like SQL Developer because it is easy to install (just unzip a jar) and has a lot of features? Me too. It can be even easier if it is provided as a web application: no installation, and no java to take all my laptop RAM… When I say no installation, you will see that you have some little things to setup here in DBaaS. That will probably be done for you in the managed…
In the previous blog posts I explained how to create, and stop/start the Autonomous Data Warehouse Cloud service. And I didn’t show yet how to connect to it. It is easy, from sqlplus or SQL Developer, or SQLcl. But there’s something more exciting to run some SQL queries: the Oracle Machine Learning Notebooks based on Apache Zepplin. At first, I didn’t realize why the administration menu entry to create users in the ADWC service was…
In the previous post, I’ve explained how to start and stop the Autonomous Data Warehouse Cloud service from PSM (PaaS Service Manager). There’s a setup phase, and a run phase starting with service-start and ending with service-stop. And the setup is specific to an Oracle Cloud account, storing information in the local user home. You may want to run different setups, and even provide an easy way to start/stop an Oracle Cloud service without knowing…
In this part of the blog posts series, we will show how ansible helps us to configure our cluster and install all pre-requisite needed for Cloudera Manager. Ansible is one of the most important automation tools currently. Ansible will help us to configure all nodes for a manual installation using Cloudera Manager. Our playbook will contain the following roles: cm_repo: add the same C.M repo into all nodes. os_config: Adjust all OS parameter for installing…
In the previous post, I explained how to create an Autonomous Data Warehouse with PSM (PaaS Service Manager Command Line Interface). The most common operation you want to do with it is starting and stopping the service. This is the best way to save credits for hourly billed services. And PSM is the easiest: run from everywhere (it is Python 3) and no need to provide credentials each time. In the previous post, I explained…
You want to try the Autonomous Data Warehouse Cloud Service? That’s easy. Here is a Step-by-Step. Cloud Credits First, you need Cloud Credits. You may have bought them (any recent negotiation with Oracle Sales, even for on-premises, involves some Cloud Credits). You can have a free trial with 300$ Cloud Credits available for 1 month. To get another month, you need a different e-mail address and different Credit Card number (not charged). It is quite…
In the last post I published the strange results I had when testing physical I/O with the latest Spectre and Meltdown patches. There is the logical I/O with SLOB cached reads.
