The promise of live patching for a Linux kernel is one which a couple of companies had been chasing for several years. today, SUSE introduced the contemporary new release of its live patching technique, with SUSE Linux agency live patching, focused on customers of SAP applications, such as the HANA in-memory database.
SUSE Linux business enterprise live Patching is available for x86-sixty four servers on top of SUSE Linux employer Server 12 service percent 1 for SAP programs, that’s SUSE’s SUSEoptimized working system platform for SAP.
stay patching for Linux has been to be had for several years thru Oracle’s kSplice generation, and both red Hat and SUSE had been operating on live patching technology that first began to appear in the Linux 4.zero kernel that debuted in April 2015.
“stay Patching from SUSE is currently the usage of the kGraft generation, evolved by SUSE Labs,” SUSE product supervisor Hannes Kuehnemund, advised ServerWatch. “components of our technology are merged upstream.”
Kuehnemund introduced that SUSE’s expectation is that through the end of the 12 months the upstream model could be presenting all features required by using establishments, so that it will allow SUSE to exchange from its very own domestic-grown technique to the upstream one. The upstream technique makes use of each kGraft in addition to factors from purple Hat’s kpatch live patching technique.
How the kGraft generation Works
In terms of the way the kGraft technology now works, it’s now not a wholesale replacement of a running kernel.
“We do not install a brand new kernel; we patch the most severe safety flaws of the strolling kernel,” Kuehnemund explained. “And yes, there may be no interruption of the application, be it SAP HANA, SAP NetWeaver or whatever else.”
The stay kernel patching for SAP applications is not the first time that SUSE has made the patching technology to be had. In November 2014, SUSE first announced organisation live Patching for SUSE Linux agency Server 12.
SUSE is also increasing its ordinary associate efforts this week with the brand new SUSE join utility catalog.
“With SUSE join, we permit a one-click installation of companion software program inside our nearby systems management framework,
