Containers

RedHat OpenShift and private repositories

For a while, I play around with RedHat CodeReady Containers and one thing annoyed me most - access to private repositories. My pet projects are GitLab and I'm not ready to expose them

RedHat CodeReady Containers update

Today my during the container start I have got notification that version 1.3.0 is available. During setup I get error that my libvrt bundle is not compatible with the new release. So you can find how I made an error and fix it.

Ansible

Ansible and Jinja Templates

Quite recently I have adopted OUD 12c configuration playbook to work with 11g PS3. And here I run into a tricky difference in configuration parameters. I'm pretty sure there are numerous ways to solve this, but my story is all about Ansible and Jinja.

Ansible

My article in #PTK magazine

UK Oracle User Group has printed my piece about RedHat Ansible and Oracle Fusion Middleware platform. Take a look and let me know if you can use it for your environments and projects. The tech part of the issue #72 could be found here.

Ansible

XML documents and Ansible

When you automate J2EE environments you can't avoid XML documents. Let's see what you can do if you should process XML as a structured data set.

WebLogic

Demo certificates in BPM 12c domain

We have found anotehr SSL hiccup in the BPM domain environment settings.

SSL

Secure Oracle HTTP Server 12c scripts

I always use custom certificates for the WebLogic servers and all the components. However, you may face connection issues with the custom NodEManager security configuration.

Ansible

Start OHS 12c no questions asked

By default, when you start domain component, such as Oracle HTTP Server instance, script prompts you for the NodeManager password. It is good security-wise, not so great for the automation.

Linux

Dude, where is my kernel?

I've got a little bit lost, trying to to install VirtualBox Guest Additions on my freshly installed and upgraded CentOS 7 virtual machine. I have tried all the tricks I found and still Virtual Box installer wont able to find my kernel headers.

OEM

OEM 13c custom certificate drama

For years I have so much of questionable syntax, partial automation support, and non-human design in Oracle products, so I could get anything with the perfect poker face. However, Oracle always has a

Oracle SOA Suite

Automate SOA Infra configuration

For the last six months, I work on the fully automated Oracle Fusion Middleware platform delivery . We use Ansible as a main automation tool and OEM for the most of the daily Ops routines.

Ghost

Break the line

My fired, Ahmed, has published few posts with the WebLogic output. And I'm sure you have seen endless output lines, especially if the system throws an exception. So he asked me: "How we can wrap the lines in code blocks?"

WebLogic

Customize properties in WebLogic 12c

WebLogic always has a way to customize environment settings for domain or even for each managed servers. WebLogic 12c introduces a new option: setUserOverrides.sh.

How-tos

Git client for Windows: basic configuration

It's quite common when you have no admin access to the workstation and proxy server with the authorization for the internet access. First part is quite easy, you can find most of the DEV tools such maven or git in portable format. Now I'll tell you how to configure proxy for git.

OEM

OEM 12c: Elusive NodeManager

I have spent a few very confusing hours in desperate attempts to figure out why OMS instance won't start. The command output suggests checking the NodeManager log file. But it has no new entries, in fact, the file wasn't accessed at all.

Ghost

Another ode to Ghost

Google knows you better, and second link from from the top was: "Hey, looks like it's your domain! Why don't you try Google Search Console?". The site hookup process is quite easy, especially if you have our domains with Google, and use the same account.

Ansible

List as a parameter

About a month ago, I developed an Ansible role to manage OPSS application policies. By original design, my role uses two lists: application role names and principals and then assigned each role to

Ghost

About syntax highlight

Ghost and syntax highlight is not a novelty at all. I used the same path as some other Ghost-busted bloggers have chosen. The final pretenders, with no drama, was prism.js and highlight.js. So, if you take a look into the site code, you would know who the winner is.

Oracle

Oracle 18c XE on Linux Mint

When things go naturally, you select an operating system, supported by the database of choice. Unfortunately, the only natural in our business is a changes. And somewhere in the middle of that, you find yourself with the task like "Hey, we need Oracle database on the Linux Mint box."
