IBM PowerVM vs. Oracle Linux

IBM PowerVM only is available on IBM POWER machines. It makes live much easier, compared to bare metal machines (OPAL) or machines with KVM. Personally I would not like to manage systems that don't have IBM PowerVM. The current line-up always includes IBM PowerVM (firmware built-in).

Oracle Linux is a very good and useful combination of the stability of Rhel and support for Oracle Databases. Our organisation uses an application and a database combo that we offer to the client but after the inclusion of Oracle Linux into our infrastructure, the provision and the operation cost are reduced significantly. So I would recommend using Oracle Linux when you are using multiple on-premises DB servers and want to move to a more secure, organised, and fast operating system.

• IBM PowerVM is used for virtualization on IBM Power series hardware to utilize the hardware resources more efficiently like micro partitioning for CPU, NPIV for fibre port...etc
• IBM PowerVM provides the feature of live partitioning mobility (LPM), which allows moving the running virtual machine from one hardware to another hardware without any disruption on a virtual machine.
• IBM Power VM provides the feature of Integrated virtual manager (IVM), which helps to manage the single IBM Power hardware. There is no need to purchase a separate hardware management console to manage the Power hardware. This works well for small organizations having small environments.

• We use Oracle Linux distro for every customer. The OS is very easy and absolutely free to develop/host and update our customers' apps and data across the globe. I personally use it in my lab to practice and test some personal stuff
• We have Oracle Linux database, WebLogic, and e-business suite hosted on Oracle Linux. It is used across our whole organization in running critical applications. It is robust, easy to manage and administer, with rock-solid stability and very minimal server reboots or performance issues. I would highly recommend Oracle Linux over other operating systems.
• Oracle Linux is trusted in high-volume, transactional, mission-critical production IT environments.
• Oracle’s Linux support is relied upon for applications that require continuous or near-continuous availability
• Application performance in general was enhanced as a result of the migration to Oracle Linux from Red Hat Enterprise Linux.
• Oracle Linux-based VMs are used in our case for hosting a spark-based cluster for processing big data-based workloads. Those VMs have better security configurations and are patched. It has built-in installed packages which come in handy for a developer to start the development activity for the project.
• We are using Oracle Linux as our primary Linux distribution deployed for our customers, but also for testing purposes on multiple test and UAT environments. Currently, it is used mainly by our department. We aim to provide commercial technical support for customers for our products, and thanks to the Oracle Linux Support program which covers Oracle Linux, we are getting assistance if needed.
• I work across many different types of organizations. In some cases, Oracle Linux is being used for all database servers across the entire organization. In some cases, it is being selectively rolled out to replace legacy Unix systems. Plus in a few isolated cases, I've helped to replace Windows database servers with Oracle Linux. The common theme across all these different types of organizations is that they want the best Linux for running Oracle, which is pre-tuned and optimized as well as well supported by the database vendor. Oracle Linux wins hands down on these points.

• The ability to run Windows. Hardware architecture does not allow this, but it is a limiting factor.
• More performance monitoring and management could be built in.
• Sometimes is marketed and packaged in some rather unusual ways

• TigerVNC needs some fine tuning in Oracle Linux 8.4.
• AutoTuning of Kernal Parameters for Oracle Databases based on the available hardware resources.
• Embedded IPA Solutions to manage large number of Oracle Linux Systems.
• Simple commands for LUN management.
• Proactive SELinux policy violation message to administrator's mailbox.

The product works. It provides the proven environment to support IBM's primary operating systems that run on the IBM Power processing systems. This by extension includes the IBM various storage products that work within that environment. It has proven to be seamless as the environment has grown and as various new products and version updates have been added. As with most IBM products, the support is excellent.

Since it is built into the firmware (hardware) it requires no separate installation (except for the Virtual I/O servers, if you need those). Both HMC and Novalink (with PowerVC) support IBM PowerVM well and offer a user-friendly interface to setting up LPARs and making changes, most on the fly. Modern systems also give insights into performance, power consumption etc. A lot of separate tools exist to show more details, like LPAR2RRD, IBM Instana, IBM Turbonomic etc.

One of the most robust Linux distributions is Redhat, its forks have given rise to infinite business models and distributions that have defined the market. Oracle Linux, obviously developed by the tech giant Oracle, is constantly releasing a flexible and incredibly stable product while adding its own bunch of new features. Among the most notable is the "Unbreakable Enterprise Kernel" (UEK).

Our company utilizes VMware and PowerVM. VMware is very user friendly from an IT support view and makes supporting Windows OS easier. PowerVM is moving in that direction. PowerVM is better in that you can prioritize workloads across different VMs and be granular in your reservation of cores and virtual CPUs. PowerVM allows you to modify VM characteristics while the VM is up and running

The Oracle Linux definitely comes on the top when it comes down to being easily available as its platform-independent. This is where the masses lie as we have moved to a hybrid work environment where keeping everyone on the same devices is no more required. Linux stands out as it allows the industry workers to implement BYOD in all environments. Software as a service is truly done by Linux. I don’t want to switch to other platforms anymore.

• We are able to run several LPARs on one frame, which means we do not need to buy as many physical servers. That saves on floor space, power, and heating and cooling of the data center, among other things.
• Using LPM allows us to do maintenance on a frame without impacting the LPARs, giving us greater uptime.

• Oracle Linux provides technical advances that Solaris UNIX does not while saving millions of dollars.
• Oracle Linux supports automated patching and easy maintenance, allowing less downtime for users and developers.
• Oracle Linux is recommended for applications already on Oracle Database and using other Oracle products and software.
• Oracle Linux is a secure, stable, and high-performance operating system that allows hybrid or cloud platforms.
