Oracle Database: Zoning Conundrum

The Oracle Database has long and complicated relations with time-aware data. It has gotten even more interesting in the internet era and global data processing. As usual, it's a story about how a single line of code at the design time could save many work hours in maintenance.

OCI

Oracle OCI: It has queues!

Oracle OCI and Amazon AWS are similar and different at the same time. Yes, at the very basic, they offer you the same services - cloud infrastructure to run your workload, but AWS always dominated by the broad set of tools, features, and capabilities if you compare them by dozens.

Standalone Oracle HTTP Server: Deployment Options

In one of my previous posts, I mentioned multiple Oracle HTTP server deployment options. Let me do a small "show & tell" to explain how I pick the configuration.

Mysterious TLS in Oracle HTTP

A little "forget-me-not" from a recent Oracle HTTP server troubleshooting, but it could happen to Apache HTTPD as well. To set up a stage: a work installation of the Oracle HTTP Server, stop presenting certificates on the secured port.

Ansible

Ansible: Consume SQL*Plus Output

A simple way to consume Oracle Database data in Ansible playbooks without extensive Python or PL/SQL coding or 3rd party modules.

Easy JDK update

Working on the integrated WebLogic server configuration, I run into a very neat Middleware 12c feature. The primary fix for the issue is to use old JDK8. When you have JDeveloper and domain configured, you can upgrade your installation to the desired JDK version, with simple steps below.

DefaultDomain in SOA Studio 12.2.1.4

I always struggle to configure internal WebLogic 12.2.x server and domain. Finally, Oracle Support helped me to complete the SOA/BPM Studio 12.2.1.4 configuration.

How Oracle Cloud helps you save on Oracle Cloud

The recent Ahmed's post on OCI client installation gave me an idea to post this piece. My Oracle Cloud trial has ended, and I have no other option but to be more budget aware. The most apparent recipe is quite similar to the basic household rule: "Turn the lights off when you leave the room."

Always free ... to go

There were a lot of talks about how the Oracle's "NextGen" Cloud is better than all the other public cloud providers and how Oracle stands out among all the other vendors with always free offerings.

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.

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.

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."
