What Is The SAP Kernel?
The SAP Kernel is a set of core programs that provides the basic functionality required by all SAP applications. It includes the operating system, database, and application server. The SAP Kernel is the foundation upon which all SAP applications are built.
Why you need ready to use SAP Kernel
Most SAP consultants agree that maintaining SAP products can be very time consuming. SAP Kernel upgrades are no exception here, as it requires a great deal of manual effort (and time!). SAP specialists are forced to perform many tedious actions, such as connecting to the server, stopping and restarting the SAP system, downloading files, placing the necessary packages in specific folders using specific archiving programs, verifying that no users are connected to the system, no jobs are running, and no other activities are being performed, making sure that all permissions are set correctly, etc.
The solution to this problem is automation powered by Avantra’s automation platform. More and more companies are starting to take notice of this opportunity and using it to save time and money. Below, we will take a closer look at the new Automated Kernel Upgrade solution from Avantra and its benefits for SAP landscape management.

What is the SAP Kernel, and why are kernel updates important?
The SAP Kernel is often called the “heart” of any SAP system, and its executable files are necessary for its successful operation. Using the latest stable kernel is vital to keep your system running smoothly.
In simple terms, the SAP Kernel is the central program that acts as the interface between an SAP application and an operating system. The kernel consists of executable programs that help start SAP, initialize memory, create buffers, begin managing user requests, as well as efficiently use hardware resources. It is also responsible for starting and stopping all application services like dispatcher, message server, collector, etc.
If SAP specialists for some reason fail to update the kernel correctly, SAP may not start and they will have to start over. There are also other serious side effects of improperly upgrading the SAP Kernel, however, they will depend on its current version.
