All the planned system shutdowns they are a problem just like the unplanned ones. In the case of machines such as servers that are offering a service, during outages this service is no longer offered and that lost time is money. Therefore, the more stable and fewer reboots an operating system needs for large machines, the better. You know that a while ago we announced a system for the kernel that prevented the system from restarting when it was updated.
Well, now SUSE Linux Enterprise Live Patching will offer a new system to avoid companies these planned stops due to updates or added patches. Thus, SAP HANA and SAP NetWeaver users can benefit from this patching system without having to restart the system and therefore avoiding critical service stops in companies that have these packages. Without a doubt, great news that will improve productivity.
As well reported from SUSE, specifically Michael miller, companies are increasingly dependent on data and that is why this type of planned downtime is still problematic. Of course the unplanned ones are even more so, since they deal with system or hardware problems that must be corrected, but from the point of view of the client or user, both have the same consequences, the temporary loss of service. The latter cannot be foreseen or avoided, but the former can ...
With this implementation, a company that has SUSE LInux Enterprise SAP HANA will be able to patch the Linux kernel without having to take down the service SAP HANA nor do you restart the server. The large volumes of data that this system supports are not compromised during the time this process takes and therefore will always be available. This is achieved thanks to some packages that the famous distribution has included to avoid these tedious reboots when updates are applied.
