oracle linux 6.5操作系统下载_oracle enterprise linux 6.5发布，下载地址详细附件。 本次甲骨文Oracle公司发布了Oracle Linux 6.5版本，这个版本包括x86 (32 bit) and x86_64 (64 bit) architectures.Oracle Linux 6 Update 5 包含了两个内核（Oracle Linux 6 Update 5 ships with three sets of kernel packages:）：The Red Hat Compatible Kernel - 直接从 Red Hat Enterprise Linux 编译而来UnbreakableEnterprise Kernel - 紧紧跟随官方 Linux 内核，并且提供最新的功能和优化的性能和稳定性。86
Unbreakable Enterprise Kernel Release 2(|kernel-uek-2.6.39-400.211.1.el6uek|) for x86 Unbreakable Enterprise Kernel Release 3 (|kernel-uek-3.8.13-16.2.1.el6uek|) for x86|_|64 OracleLinux 6.5版本的更新说明与新功能介绍如下：87
Red Hat Compatible Kernel (|kernel-2.6.32-431.el6|) for x86 and x86_64 By default, both the Unbreakable Enterprise Kernel and the Red Hat Compatible Kernel are installed. UEK R3 includes the following major improvements over UEK R2: Integrated DTrace support in the UEK R3 kernel and user-space tracing of DTrace-enabled applications.

Device mapper support for an external, read-only device as the
origin for a thinly-provisioned volume.
The|loop|driver provides the same I/O functionality as|dm-nfs|by
extending the AIO interface to perform direct I/O. To create the loopback device, use the*
losetup*command instead of*dmsetup*.

The|dm-nfs|module is not provided with UEK R3.
Btrfs*send*and*receive*subcommands allow you to record the
differences between two subvolumes, which can either be snapshots of
the same subvolume or parent and child subvolumes. Btrfs quota groups (/qgroups/) allow you to set different size
limits for a volume and its subvolumes.

Btrfs supports replacing devices without unmounting or otherwise disrupting access to the file system.
Ext4 quotas are enabled as soon as the file system is mounted.
CP controlled delay management (/CoDel/) is a new active queue
management algorithm that is designed to handle excessive buffering across a network connection (/bufferbloat/). The algorithm is based on for how long packets are buffered in the queue rather than the
size of the queue. If the minimum queuing time rises above a threshold value, the algorithm discards packets and reduces the transmission rate of TCP.

TCP connection repair implements process checkpointing and restart, which allows a TCP connection to be stopped on one host and restarted on another host. Container virtualization can use this feature to move a network connection between hosts.
TCP and STCP early retransmit allows fast retransmission (under certain conditions) to reduce the number of duplicate acknowledgements. TCP fast open (TFO) can speed up the opening of successive TCP connections between two endpoints by eliminating one round time trip (RTT) from some TCP transactions. The TCP small queue algorithm is another mechanism intended to help deal with bufferbloat. The algorithm limits the amount of data that can be queued for transmission by a socket.

The secure computing mode feature (/seccomp/) is a simple sandbox mechanism that, in strict mode, allows a thread to transition to a state where it cannot make any system calls except from a very restricted set (|_exit()|,|read()|,|sigreturn()|, and|write()|) and it can only use file descriptors that were already open. In filter mode, a thread can specify an arbitrary filter of permitted systems calls that would be forbidden in strict mode. Access to this feature is by using the|prctl()|system call. For more information, see the|prctl(2)|manual page.

The OpenFabrics Enterprise Distribution (OFED) 2.0 stack supports the following protocols:

SCSI RDMA Protocol (SRP) enables access to remote SCSI devices
via remote direct memory access (RDMA)
iSCSI Extensions for remote direct memory access (iSER) provide
access to iSCSI storage devices
Reliable Datagram Sockets (RDS) is a high-performance,
low-latency, reliable connectionless protocol for datagram delivery
Sockets Direct Protocol (SDP) supports stream sockets for RDMA
network fabrics
Ethernet over InfiniBand (EoIB)
IP encapsulation over InfiniBand (IPoIB)
Ethernet tunneling over InfiniBand (eIPoIB)

The OFED 2.0 stack also supports the following RDS features:
Async Send (AS)
Quality of Service (QoS)
Automatic Path Migration (APM)
Active Bonding (AB)
Shared Request Queue (SRQ)
Netfilter (NF)
Paravirtualization support has been enabled for Oracle Linux guests on Windows Server 2008 Hyper-V or Windows Server 2008 R2 Hyper-V.
The Virtual Extensible LAN (VXLAN) tunneling protocol overlays a virtual network on an existing Layer 3 infrastructure to allow the transfer of Layer 2 Ethernet packets over UDP.
This feature is intended for use by a virtual network infrastructure in a virtualized environment. Use cases include virtual machine migration and software-defined networking (SDN).
