The software described in this documentation is either in Extended Support or Sustaining Support. See https://www.oracle.com/us/support/library/enterprise-linux-support-policies-069172.pdf for more information.
Oracle recommends that you upgrade the software described by this documentation as soon as possible.
The following features included in the Unbreakable Enterprise Kernel Release 2 are still under development, but are made available for testing and evaluation purposes.
Kernel module signing facility
Applies cryptographic signature checking to modules on module load, checking the signature against a ring of public keys compiled into the kernel. GPG is used to do the cryptographic work and determines the format of the signature and key data.
Linux Containers (lxc)
Based on the Linux Cgroups and name spaces functionality, containers allow you to safely and securely run multiple applications or instances of an operating system on a single host without risking them interfering with each other. Containers are lightweight and resource-friendly, which saves both rack space and power. In order to get started with containers, you need to install the
lxc
package, which is included in the package repository of the Unbreakable Enterprise Kernel.Transcendent memory (tmem)
Transcendent Memory provides a new approach for improving the utilization of physical memory in a virtualized environment by claiming underutilized memory in a system and making it available where it is most needed. From the perspective of an operating system, tmem is fast pseudo-RAM of indeterminate and varying size that is useful primarily when real RAM is in short supply. To learn more about this technology and its use cases, see the Transcendent Memory project page on oss.oracle.com: https://oss.oracle.com/projects/tmem/
Distributed Replicated Block Device (DRBD)
A shared-nothing, synchronously replicated block device (RAID1 over network), designed to serve as a building block for high availability (HA) clusters. It requires a cluster manager (for example, pacemaker) to implement automatic failover.
The following Technology Preview features are currently not supported under Oracle Linux 6 and may not be functionally complete:
DIF/DIX support for SCSI
FS-Cache
fsfreeze
IPv6 support in IPVS
LVM API
LVM RAID support
Matahari
Open multicast ping (
omping
)System Information Gatherer and Reporter (SIGAR)
Trusted Platform Module (TPM)
Trusted Boot
vios-proxy
The following Technology Preview features are only available when running the Red Hat Compatible Kernel (RHCK):
Brocade BFA driver
Diagnostic pulse for the
fence_ipmilan
agentError Detection And Correction (EDAC) driver interface
Fibre Channel over Ethernet (FCoE) target mode
Kernel Media support
KVM Live Snapshots
KVM network drivers wire-speed requirement
Parallel NFS
Remote audit logging
Single Root I/O Virtualization (SR-IOV) on the
be2net
driverSystem monitoring via SNMP
These features are not suitable for production use, but are included to give them wider exposure.
