If you are an administrator of Oracle Solaris 11 systems you will very likely be aware that several of the critical installation and management tools are implemented in Python rather than the more traditional C and/or shell script. Python is often a good choice as a systems development language and Oracle Solaris is not alone in choosing to use it more extensively. If you have done any programming with Python or have installed other Python tools you are probably aware that...

Following on to my previous posts on using Oracle Solaris with Oracle Cloud Infrastructure (OCI)... All modern clouds provide a fancy browser console that lets you easily manage any of your cloud resources. For power users, though, the browser console is often the slowest way to get things done. Plus, if you're trying to leverage the cloud as part of other automation, which has often been written as traditional Unix shell scripts,you may need a command line interface (CLI),...

This post is in part tong-in-cheek, and in part serious. Last week someone told me that even the NSA (yes the National Security Agency of the USA) now advises to upgrade to Oracle Solaris 11.4 and my initial thought was "sure they do", but I was swiftly pointed to this very recent Cybersecurity Advisory they had put out (which also acts as guidance for the various government agencies). And sure enough, it states: "Upgrade to Solaris® 11.4 from earlier versions of Solaris® and...

1) Function Pointers Declaring Function Pointers Similar to a variable declared as pointer to some data type, a variable can also be declared to be a pointer to a function. Such a variable stores the address of a function that can later be called using that function pointer. In other words, function pointers point to the executable code rather than data like typical pointers. eg., void (*func_ptr)(); In the above declaration, func_ptr is a variable that can point to a...

Continuing my series of posts on how to use Oracle Solaris in Oracle Cloud Infrastructure (OCI), I'll next explore using Solaris Zones in OCI. In this post I assume you're somewhat familiar with zones already, as they've been around since we released Solaris 10 in 2005. Before diving in, there's a little terminology to review. The original zones introduced in Solaris 10 are known as non-global zones, which share a kernel with the global zone but otherwise appear to...

Target Audience: Oracle SuperCluster customers The primary objective of this blog post is to provide some related information on this obscure tool to inquisitive users/customers as they might have noticed the osc-interdom service and the namesake package and wondered what is it for at some point. SuperCluster InterDomain Communcation Tool, osc-interdom, is an infrastructure framework and a service that runs on Oracle SuperCluster products to provide flexible monitoring and...

After getting started by importing an Oracle Solaris image into your Oracle Cloud Infrastructure (OCI) tenant and launched an instance, you'll likely want to use other OCI resources to run your applications. In this post, I'll provide a quick cheat sheet to using the storage resources: block volumes and file storage. I'm not going to cover the basics of creating these objects in OCI, which is covered well by the documentation. This post just shows how to do the...

The examples shown in this blog post were created and executed on a Solaris system. Some of these tips and examples are applicable to all *nix systems. Digest of a File One of the typical uses of computed digest is to check if a file has been compromised or tampered. The digest utility can be used to calculate the digest of files. On Solaris, -l option lists out all cryptographic hash algorithms available on the system. eg., % digest -l sha1 md5 sha224 sha256 .. sha3_224...

With today's release of Oracle Solaris 11.4, we're making pre-built images available for use in Oracle Cloud Infrastructure (OCI). The images aren't part of the official OCI image catalog at this time, but using them is easy, just follow these steps, which are the same as in my previous post on the 11.4 beta images. Login to your OCI console and select Compute->Custom Images from the main menu, this will display the Images page. Press the blue Import Image button. This will...
