Questa versione contiene (in Inglese):

Oracle is pleased to announce the availability of the Oracle Linux 8 Update 4 for the 64-bit Intel and AMD (x86_64) and 64-bit Arm (aarch64) platforms.  Oracle Linux brings the latest open source innovations, business-critical performance, and security optimizations for cloud and on-premises deployment. Oracle Linux maintains user space compatibility with Red Hat Enterprise Linux (RHEL) and CentOS, which is independent of the kernel version that underlies the operating system. Existing applications in user space will continue to run unmodified on Oracle Linux 8 Update 4 with Unbreakable Enterprise Kernel Release 6 (UEK R6) and applications already certified on  previous releases of Red hat Enterprise Linux 8 or Oracle Linux 8 do not require a certification with this new release.

Oracle Linux 8 Update 4 includes the UEK R6 Update 2 on the installation image, along with the Red Hat Compatible Kernel (RHCK). For new installations, UEK R6 is enabled and installed by default and is the default kernel on first boot. UEK R6, the kernel developed, built, and tested by Oracle is based on the mainline Linux Kernel 5.4, and deliversmore innovation than other commercial Linux kernels.

Oracle Linux 8 Update 4 release includes:

• Dynamic Programming Languages
  • Updated module streams include python39:3.0, swig:4.0, subversion:1.14 and redis:6.
  • mysql-selinux packageincludes an SELinux module that provides rules for the MySQL database.

• Red Hat Compatible Kernel (RHCK)
  • EDAC module included. (EDAC) kernel module, part of RHCK, primarily handles Error Code Correction (ECC) memory and detects and reports PCI bus parity errors.
  • Free memory page feature added. The Oracle Linux 8 host kernel is capable of returning memory pages that are not used by its VMs back to the hypervisor. This feature change improves the stability and resource efficiency of the host.
  • kmod-redhat-oracleasm package added.  The kmod-redhat-oracleasm package has been added in this release. This package provides the kernel module part of the ASMLib utility. Oracle Automated Storage Management (ASM) is a data volume manager for Oracle databases. ASMLib is an optional utility that you can use on Oracle Linux systems to manage Oracle ASM devices.
  • Note: those features was formerly only available in the Unbreakable Enterprise Kernel.
