Why You Should Periodically Review Your Backups

Introduction

So like every good Oracle DBA, you’ve created a few databases, decided that if they were worth creating and using they might also be worth backing up, and created some backup scripts that do ample logging. All hunky dory, right? You shouldn’t need to revisit this, right?

WRONG!!!

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.

Duplicating a Database on ODA

Introduction

Every so often, we get a request to duplicate a database for one of our customers using an Oracle Database Appliance (ODA). The process for doing that is relatively straightforward, but there are a couple of nuances along the way so I thought I’d write it up as a blog post in case it’s of use to others. Obviously, I have obfuscated any customer-specific information to protect their identity.

Configuration

The first nuance is to understand what database is being used as the source for the clone. Generally, a request for cloning will be something like this:

“We are creating a new environment which needs a new database to be set up. Please copy P1_SRV_T and restore as P1_SRV_F”.

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:
