Superstar Saar just released a new set of Oracle VM templates.
I was looking at snmp for a few days and decided to put together a little snmp module (extension) that would work on Oracle VM Server (3.2 and up). In 3.2 we started to include the net-snmp rpms to allow customers to monitor any given Oracle VM server with standard SNMP tools. Whether that be cacti, snmpwalk, even Oracle Enterprise Manager (snmp fetchlets) or whatever tool.
Another frequently asked question related to Oracle Linux is how versions of specific packages (RPMs) are picked.
A Linux distribution is basically a collection of a ton of open source projects that make up the Operating System environment, with at its core the Linux kernel. Linux as a development project is about the Linux kernel specifically. There are then many (1000's) of random open source projects out there and a Linux distribution basically is an OS made up of, at its core, the kernel, and tons of those other projects packaged up.
A frequently discussed topic inside Oracle and also outside with customers and partners is Oracle Linux versions and how to treat updates and support and certifications and minimum levels. Here's our take on it, from the Oracle Linux side.
When talking about Oracle Linux and versions, there really are 3 major components :
-1- A major new release, such as Oracle Linux 5, Oracle Linux 6,...
A major new release is an update of the entire OS, kernel, userspace, all the 1000's of packages that make up Oracle Linux.
It's been exactly two years since we acquired a small startup called Ksplice. Ksplice as a company created the zero downtime update technology for the Linux kernel and they provided a service to their customers which tracked Linux kernel security fixes and providing these fixes as zero downtime Ksplice updates.
Essentially the ksplice technology allows us to create Linux kernel patches that can be applied in an online fashion. We are not talking about the ability to install a patch while the system is running and make it active after reboot.
Someone forwarded a document to me earlier today that had Some Company make a statement that implied that Oracle Clusterware was not free with Oracle Linux. I found it sort of amuzing because I think we've been rather clear on this for quite some time.
So let me spell it out to make sure it's very, very clear.
When a customer purchases Oracle Linux support subscriptions (Basic, Basic Limited, Premier, Premier Limited) or purchases an Oracle x86 server with Support, they have the full right-to-use included for Oracle Clusterware without any additional fees.
This week we released the latest version of our database, Oracle database 12c Release 1.
Finally found some time to play with ovm_utils again and added another little tool to the package.
ovm_utils is a collection of little tools I wrote over the last year or 2. They can help make command line use a little easier. Of course we have since introduced a real ovm_cli in Oracle VM Manager in 3.1 which is officially part of the product and officially supported. ovm_utils is provided as-is, for fun.
So a nasty bug report came out the other day on linux, a serious exploit.
