Enterprise Manager Silent Installation


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.

Generating the Response Files

Unlike all the other installations and configurations using response files, for some reason Oracle Corporation in its (more...)

Creating the Listener and Database in Silent Mode


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.


Just (more...)

Duplicating a Database on ODA


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.


The first nuance is (more...)

Post GI / RDBMS Installation Configuration Steps


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. (more...)

Silent Installation of the RDBMS


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 (more...)

Silent Installation of Grid Infrastructure


Recently I had a requirement to install the Grid Infrastructure and Oracle RDBMS on a completely new VM. The customer I was doing this work for wanted to take a copy of their Production environment to another server so they could test an upgrade of their existing environment from Oracle GI / RDBMS 12.1 to 12.2. So they built a VM for me, copied the 12.1 installation media for both GI (more...)

Extending a Logical Volume Group


Today I ran into the situation where I needed to extend a logical volume group so I could complete an installation. I’d already installed the Grid Infrastructure, but there wasn’t enough room remaining to install the Oracle kernel on the same device. This is for a test environment which was being built on a VM that had just been created, and performance is not the issue we’re looking at here, so installing the Grid (more...)

Enterprise Manager and Firewalls

Just a short post, since this is a fairly common question I see. This morning someone asked me a question about Enterprise Manager and firewalls. They have an environment with EM targets placed in different zones / networks – with firewalls between. In the documentation, it states “Each Management Agent is configured to upload data to one OMS. As a result, if there is a firewall between the Management Agent and its OMS, you must (more...)

That demned elusive PQ slave

With apologies to Emma Orczy for stealing a line from “The Scarlet Pimpernel” … ????


We ran into a strange situation at a customer site this morning. A customer asked us to kill two stuck sessions on one of their RAC Exadata environments, normally something they have sufficient knowledge and access to be able to handle themselves. Well this time round, every time they issued an “ALTER SYSTEM KILL SESSION ‘xxx, (more...)

Moving SYSAUX from one diskgroup to another


This is another of the posts on how I did something to remind me how to do it again, when next the need arises. ????

Situation here was a customer who was running out of space in their Production database due to the unified audit trail bug in early versions of 12.1. Their SYSAUX tablespace had blown out to 186 GB, and their ASM diskgroup had run into negative space territory (i.e. if (more...)
