Table of Contents
This section describes new features and changes in Update 2 for Oracle Linux 7.
For details of the new features and changes in the initial release of Oracle Linux 7, see the Oracle Linux 7 Release Notes.
You can install Oracle Linux 7 on x86-64 systems with up to 2048 logical CPUs and 64 TB of memory. The theoretical upper limit is 5120 logical CPUs and 64 TB of memory, but Oracle has not tested this configuration. A minimum of 2 logical CPUs and 1 GB of memory per logical CPU is recommended. Although the minimum disk space required for installation is 1GB, a minimum of 5 GB is recommended.
The following table lists the maximum file size and maximum file system size for the btrfs, ext4, and XFS file systems.
File System Type | Maximum File Size | Maximum File System Size |
|---|---|---|
btrfs | 50 TB | 50 TB |
ext4 | 50 TB | 50 TB |
XFS | 16 TB | 500 TB |
The maximum supported size for a bootable LUN is 50 TB. GPT and UEFI support are required for LUNs larger than 2 TB.
The maximum size of the address space that is available to each process is 128 TB.
Oracle Linux 7 Update 2 includes the following kernels:
kernel-3.10.0-327.el7Red Hat Compatible Kernel (RHCK).
kernel-uek-3.8.13-98.6.1.el7uekUnbreakable Enterprise Kernel Release 3 (UEK R3), which is the default kernel.
makedumpfile can now use sadump format for dumps
of more than 16 TB of physical memory.
It is now possible to configure Kdump during non-graphical installation. For
limitations on using the crashkernel=auto setting, see Section 3.4, “Crash Kernel auto Setting”.
Oracle Linux 7 includes the Keepalived and HAProxy technologies for balancing access to network services while maintaining continuous access to those services.
Keepalived uses the IP Virtual Server (IPVS) kernel module to provide transport layer (Layer 4) load balancing, redirecting requests for network-based services to individual members of a server cluster. IPVS monitors the status of each server and uses the Virtual Router Redundancy Protocol (VRRP) to implement high availability.
HAProxy is an application layer (Layer 7) load balancing and high availability solution that you can use to implement a reverse proxy for HTTP and TCP-based Internet services.
For more information, see Load Balancing and High Availability Configuration in the Oracle Linux 7 Administrator's Guide.
In the initial release of Oracle Linux 7, the MySQL Community 5.6 packages were provided on the Oracle Linux 7 full installation DVD image but were not installable using the Anaconda installer or kickstart. The ISO image for this update to Oracle Linux 7 provides support for installing either MySQL 5.6 or MariaDB by using either the Anaconda installer or kickstart.
It is not possible to install MySQL and MariaDB on the same system as package conflicts exist. Installing the MySQL packages replaces any conflicting MariaDB packages.
By default, neither MySQL 5.6 packages nor MariaDB packages are installed. It is possible to install either the MySQL 5.6 package group or the MariaDB package group on a system by using the graphical installer or kickstart, but not both package groups.
To install the MySQL 5.6 packages using kickstart, specify the
@mysql package group in the %packages section. If
you also specify @mariadb, it is ignored.
To install the MariaDB packages using kickstart, specify @mariadb
but not @mysql in the %packages section.
If you want to install MariaDB, you must deselect the MySQL repository. Otherwise, MySQL is installed even if you select only the MariaDB group. (Bug ID 22238684)
The MySQL Community 5.7, MySQL Community 5.6 and MySQL Community 5.5 packages are also available on the Unbreakable Linux Network (ULN) and Oracle Public Yum.
It is not necessary to install the Spacewalk client before registering an Oracle Linux 7 Update 2 system with a Spacewalk server. Instead, you can use the rhnreg_ks command, specifying the server URL and the activation key to be associated with the system.
If the server URL does not have a HTTP secure address, use the following command:
# rhnreg_ks --serverUrl=http://spacewalk_server/XMLRPC --activationkey=activation_keyIf the server URL has a HTTP secure address:
Download the CA certificate file RHN-ORG-TRUSTED-SSL-CERT to
the server.
In a browser tab, navigate to
http://, where
swksvr_FQDN/pubswksvr_FQDN is the fully qualified domain name of the
Spacewalk server, and download the CA certificate file
RHN-ORG-TRUSTED-SSL-CERT to
/usr/share/rhn/.
Alternatively, you can use wget from the command line, for example:
#wget -q -O /usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT\http://swksvr_FQDN/pub/RHN-ORG-TRUSTED-SSL-CERT
Register the system with Spacewalk using the rhnreg_ks command, using the --sslCACert option to specify the certificate.
#rhnreg_ks --sslCACert=/usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT\--serverUrl=http://swksvr_FQDN/XMLRPC --activationkey=activation_key
Specify the Spacewalk server or proxy by its fully qualified domain name.
If you need to re-register a Spacewalk client with a Spacewalk server, additionally specify the --force option.
Oracle recommends installing the full Spacewalk client after registration to support all of the features provided by Spacewalk, which include provisioning and auditing.
To install the Spacewalk Client software after registration, subscribe the server to a Spacewalk Client 2.2 software channel and use yum to install the packages:
# yum install rhn-client-tools rhn-check rhn-setup rhnsd m2crypto yum-rhn-pluginThe following features are still under development, but are made available for testing and evaluation purposes with UEK R3:
Ceph
Ceph presents a uniform view of object and block storage from a cluster of multiple physical and logical commodity-hardware storage devices. Ceph can provide fault tolerance and enhance I/O performance by replicating and striping data across the storage devices in a Storage Cluster. Ceph's monitoring and self-repair features minimize administration overhead. You can configure a Storage Cluster on non-identical hardware from different manufacturers.
Ceph for Oracle Linux is based on the Ceph Community Firefly release (v0.80). It includes the Object Store, Block Device, Storage Cluster, and Object Gateway components of Ceph. The Ceph file system (CephFS) component is also included but it is neither a technical preview feature nor is it supported.
For more information, see the Ceph for Oracle Linux Technology Preview Release Notes.
Deo Network Bound Disk Encryption
Deo (formerly known as Petera) enables the automated decryption of encrypted disks on systems inside an enterprise firewall and is intended to ensure that the data remains secure should an encrypted disk be removed from the network. You use the deo command first to enable automated decryption of an encrypted disk and subsequently to fetch and use the decryption key to unlock the disk.
For use case suggestions, see New Deo Design and Automatic decryption of TLS private keys with Deo.
For more information, see Network Bound Disk
Encryption and the deo(1) manual page.
DRBD (Distributed Replicated Block Device)
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) for automatic failover.
SCAP Workbench and the OSCAP Anaconda add-on
The OpenSCAP add-on to the Installer allows you to select a Security Content
Automation Protocol (SCAP) policy by using either the graphical interface or a Kickstart
% addon org_fedora_oscap section. At the end of the installation
process, the compliance scanning utility (openscapscanner) scans the
system and saves the results to /root/openscap_data. The installation
supports a number of standard security profiles that are provided by the
scap-security-guide package. Alternatively, you can choose to use
profiles from an accessible FTP or web server. By default, the Installer neither applies
a security policy nor performs a compliance scan.
Transcendent memory
Transcendent Memory (tmem) 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 at http://oss.oracle.com/projects/tmem/.
UEFI Secure Boot
This update allows you to install and use Oracle Linux 7 on systems that have enabled UEFI Secure Boot. A system in Secure Boot mode will load only boot loaders and kernels that have been signed by Oracle.
For the RHCK, the following features are currently under technology preview:
Active Directory and LDAP sudo providers.
Block and object storage layouts for parallel NFS (pNFS).
Block device caching by LVM, which allows small, fast devices to act as caches for large, slow devices.
btrfs file system. Oracle supports btrfs with UEK R3.
Crash kernel can be configured to boot with more than a single CPU.
DIF/DIX for data integrity checking on SCSI devices other than certain, specified native HBA and storage hardware. Oracle supports DIF/DIX with UEK R3.
LSI Syncro CS feature in the megaraid_sas driver to support
High-Availability Direct-Attached storage (HA-DAS) adapters.
LVM API.
More than 32 PCI slots can be configured with PCI Bridge in QEMU.
OpenLMI Software Provider.
PCI Express Bus, AHCI Bus, and USB 3.0 host adapter emulation are provided for KVM guests.
Single-Root I/O virtualization (SR-IOV) in the qlcnic driver.
Storage array management, which includes a command-line interface and the libStorageMgmt API.
The dm-era device-mapper target records changes made to blocks
over a specified time period.
Trusted Network Connect.
virtio-blk-data-plane in Quick EMUlator (QEMU) improves block I/O
performance.
The upstream Kpatch RPM has been removed from Oracle Linux. Customers who wish to patch their running kernel with zero downtime should evaluate Oracle's Ksplice technology, which is included at no additional cost with Oracle Linux Premier support.
Oracle Linux maintains user-space compatibility with Red Hat Enterprise Linux, which is independent of the kernel version that underlies the operating system. Existing applications in user space will continue to run unmodified on the Unbreakable Enterprise Kernel Release 3 (UEK R3) and no re-certifications are needed for RHEL certified applications.
To minimize impact on interoperability during releases, the Oracle Linux team works closely with third-party vendors whose hardware and software have dependencies on kernel modules. The kernel ABI for UEK R3 will remain unchanged in all subsequent updates to the initial release. UEK R3 contains changes to the kernel ABI relative to UEK R2 that require recompilation of third-party kernel modules on the system. Before installing UEK R3, verify its support status with your application vendor.
The following Emulex LightPulse HBA devices are being desupported by Emulex and are not supported for use with Oracle Linux 7:
LP10000 (VID:10DF, DID:FA00)
LP10000S (VID:10DF, DID:FC00)
LP101 (VID:10DF, DID:F0A1)

Table of Contents
This chapter describes the fixed issues for Oracle Linux 7 Update 2.
A kernel panic no longer occurs with UEK R3 quarterly update 7 or later (kernel version 3.8.13-118 or later) if all the inodes for an XFS file system are used. (Bug ID 19695297)
Table of Contents
This chapter describes the known issues for Oracle Linux 7 Update 2.
The daemons and features provided by the Red Hat Automatic Bug Reporting Tool (ABRT)
are not supported with Oracle Linux. ABRT packages and associated files, such as
libreport, are included in the distribution to satisfy package
dependencies, but the features within these packages are not supported. For technical
assistance, contact Oracle Support via the My Oracle Support portal or by telephone.
Pressing the Tab key to complete commands automatically in the bash shell works for some commands such as ls but not for other commands such as export. You can use the following workaround to enable autocompletion for all commands:
Remove the bash-completion package:
# yum remove bash-completion Run the complete -r command in the shell. To make this command
persistent, you could put it in $HOME/.bashrc.
(Bug ID 19248362)
Mounting and formatting Ceph block devices is available as a technical preview with UEK R3. See the Ceph for Oracle Linux Release Notes. (Bug ID 20304006)
If you enable the crashkernel=auto kernel parameter for UEK R3 to
simplify Kdump configuration, both dmesg output and
/proc/cmdline show
crashkernel=. This is the expected
behavior for the implementation, where NNNM@0M@0M implies the
auto setting. The crashkernel=auto parameter is not
supported for Xen.
Docker 1.8.3 fails to start if SELinux is enabled. The workaround is to disable SELinux. (Bug ID 22258930)
The following error message indicates that IPv6 NAT is not currently supported by
firewalld with UEK R3.
ERROR: ipv6 table 'nat' does not exist (or not enough permission to check)
(Bug ID 18504545)
If grubby is used to remove a kernel menu entry from the GRUB 2
configuration, the value of the default entry in /etc/grub2/grub.cfg is
incorrect. The workaround is to set the value of GRUB_DEFAULT in
/etc/default/grub to the correct entry and use
grub2-mkconfig to recreate /etc/grub2/grub.cfg, or
use yum or rpm to remove the kernel packages. (Bug ID
19192278)
Installing the tex-fonts-hebrew package fails unless you first
install all texlive* packages. (Bug ID 19059949)
The following sections describe issues that might be encountered when using InfiniBand devices.
To configure Internet Protocol over InfiniBand (IPoIB):
Edit the
/etc/sysconfig/network-scripts/ifcfg-ib
configuration file, where NN is the number of the interface.
The following example shows the configuration for the interface
ib0:
DEVICE=ib0 TYPE=InfiniBand ONBOOT=yes DHCP_HOSTNAME="myhost.mydom.com" BOOTPROTO=static IPADDR=192.168.100.1 NETMASK=255.255.255.0 IPV4_FAILURE_FATAL=yes IPV6INIT=no CONNECTED_MODE=no NAME=ib0
Stop the NetworkManager service:
# systemctl stop NetworkManagerStart the RDMA service:
# systemctl start rdmaBring up the interface:
# ifup ibN(Bug ID 19150870)
The IPoIB driver supports the use of either connected mode or datagram mode with an
interface, where datagram mode is the default mode. Changing the mode of an InfiniBand
interface by echoing either connected or datagram to
/sys/class/net/ib is not
supported. It is also not possible to change the mode of an InfiniBand interface while it
is enabled. N/mode
To change the IPoIB mode of an InfiniBand interface:
Edit the
/etc/sysconfig/network-scripts/ifcfg-ib
configuration file, where NN is the number of the
interface:
To configure connected mode, specify CONNECTED_MODE=yes
in the file.
To configure datagram mode, either specify
CONNECTED_MODE=no in the file or do not specify this
setting at all (datagram mode is enabled by default).
Before saving your changes, make sure that you have not specified more than
one setting for CONNECTED_MODE in the file.
To enable the specified mode on the interface, use the following commands to take down the interface and bring it back up:
#ifdown ib#Nifup ibN
(Bug ID 17479833)
You might see the following warning messages if you use the ibportstate disable command to disable a switch port:
ibwarn: [2696] _do_madrpc: recv failed: Connection timed out ibwarn: [2696] mad_rpc: _do_madrpc failed; dport (Lid 38) ibportstate: iberror: failed: smp set portinfo failed
You can safely ignore these warnings. (Bug ID 16248314)
The following sections describe issues that might be encountered during installation.
During installation, if you select Encrypt my data on the Installation Destination screen and then perform manual partitioning, the Encrypt check box is not shown as selected on the Manual Partitioning screen. This check box refers to encryption that you can configure on a file system type that supports encryption or on an LVM logical volume that contains the file system. If you click Modify, the Encrypt check box on the Configure Volume screen is shown as selected for the volume, meaning that the encryption will be applied at the level of the underlying block device.
For LVM, selecting Encrypt my data encrypts the LVM physical volume and all the logical volumes that it contains. If you do not select Encrypt my data, you can encrypt the logical volume by selecting the Encrypt check box on the Manual Partitioning screen or encrypt the physical volume by selecting the Encrypt check box on the Configure Volume screen.
For btrfs, encryption can only be applied to the block device that contains the file
system, including its subvolumes. For example, enabling encryption for the
/home subvolume of a btrfs root file system implicitly enables
encryption for the root file system itself. You can only select the Encrypt check box on the Configure Volume screen. As btrfs does
not support encryption at the file-system level, you cannot select the Encrypt check box on the Manual Partitioning screen for a btrfs
file system.
Do not select the Encrypt check box or a BTRFS, LVM, or LVM Thin Provisioning device type for /boot.
The /boot file system must be configured on a standard partition and
should be of type ext4 or XFS.
When entering a password in the Disk Encryption Passphrase dialog, press Tab to move between the entry fields. You cannot use the mouse to select the fields.
Attempting to perform a network installation without configuring a network interface
to use DHCP to obtain its IP settings or with static IP settings results in the error
Error in Installation Source.
For example, if you use a feature such as a remote console or Lights-out management to access a boot ISO, the network configuration of the embedded server manager might not be available when you select the installation location. The workaround is to use the graphical installer to configure the network settings manually before configuring the installation location. (Bug ID 19047736)
When installing on an iSCSI disk, add either ip=ibft or
rd.iscsi.ibft=1 to the boot command line and specify at least one MBR
or GPT-formatted disk as an installation target. Otherwise, the installation fails with
the error message No valid boot loader target device found. (Bug ID
22076589)
The UEK R3 does not support the QAT driver that allows cryptographic capabilities to be offloaded to QuickAssist hardware.
If you want to install MariaDB, you must deselect the MySQL repository. Otherwise, MySQL is installed even if you select only the MariaDB group. (Bug ID 22238684)
Running the multipath -ll command under UEK R3 produces messages such as the following:
zram0: No fc_host device for 'host' zram0: No fc_host device for 'host' zram0: No fc_remote_port device for 'rport--1:-1-0'
You can ignore these message as there is no effect on multipath functionality. You can
prevent the messages from occurring by blacklisting the zram device in
/etc/multipath.conf, for example:
blacklist {
devnode "^(ram|zram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
}(Bug ID 20300644)
The Network Priority cgroup subsystem (net_prio) is not currently
supported for use with UEK R3. Attempting to use the module with UEK R3 results in error
messages such as the following:
modprobe: FATAL: Module netprio_cgroup not found mount: special device cgroup does not exist.
(Bug ID 18966564)
The network connection icon might report an active network interface as being
disconnected. This behavior is seen for the root user but not for other
users. Command-line utilities such as ip link and
ifconfig report the correct state. (Bug ID 19060089)
The following sections describe issues that might be encountered when using NFS.
Attempting to create an lxc-oracle container on a remote file
system mounted using NFS v4 fails. In addition, attempting to mount a remote file system
using NFS v4 from within an lxc-oracle container also fails. The
workaround is to use NFS v3 instead. (Bug ID 16316266)
The oracleasm script fails if SELinux is in
Enforcing mode. The suggested workaround is to disable the SELInux
policy module for Oracle ASM before running oracleasm:
#semodule -d oracleasm#semodule -l | grep oracleasmoracleasm 1.0.0 Disabled
(Bug ID 18513404)
Oracle Linux 7 guests are supported for both hardware virtualization (HVM) and hardware virtualization with paravirtual drivers (PVHVM) on Oracle VM 3. Oracle Linux 7 guests in a paravirtualized domain (PVM) on Oracle VM or other Xen-based hypervisors are not supported.
Oracle Linux 7 guests of any type are not supported on Oracle VM 2.
Per-CPU allocation fails when the kvm_intel module is loaded with
UEK R3. Messages such as the following are logged:
kvm_intel: Could not allocate 48 bytes percpu data PERCPU: limit reached, disable warning
There is no current workaround for UEK R3. (Bug ID 18459498)
The systemctl command supports the disable,
enable, restart, start,
status, and stop actions for services such as
o2cb and oracleasm. To perform actions such as
configure, invoke the /etc/init.d script for the
service directly. (Bug IDs 18527520 and 18528039)
At boot time, systemd fails to load the autofs4
and ipv6 modules and errors such as the following are logged:
systemd[1]: Failed to insert module 'autofs4' systemd[1]: Failed to insert module 'ipv6'
There is no current workaround for UEK R3. (Bug ID 18470449)
Updating Oracle Linux 7 fails if you have installed the i686 versions of the
krb5-server and krb5-server-ldap packages on a
system. Remove these packages before updating the system, for
example:
# yum remove krb5-server.i686 krb5-server-ldap.i686(Bug ID 20671170)
The following sections describe issues that might be encountered when upgrading from
Oracle Linux 6 (_latest) to Oracle Linux 7 Update 2.
The libcgroup package in Oracle Linux 7 does not include the
cgconfig and cgred control group services. To
restore these services on an upgraded system, install the
libcgroup-tools package. (Bug ID 19177606)
The postupgrade scripts fail if a proxy is required to access Oracle Public Yum. (Bug ID 19169163)
If you do not run the preupgrade assistant utility preupg, an
upgraded system hangs while rebooting with the message starting wait for plymouth
boot screen to quit. (Bug ID 18815298)
The old RHCK is not removed during the upgrade. (Bug ID 18767222)
The redhat-upgrade-tool-cli utility does not exit if UEK R3 is not installed. (Bug ID 18900135)
The redhat-upgrade-tool-cli utility requires that you install
version 3.2.29-43.0.1 or later of the yum package on the Oracle Linux 6
system that you want to upgrade. If you use an earlier version of the
yum package, the upgrade tool fails with dependency errors. (Bug ID
18648783)

If installed, remove the i686 versions of the krb5-server and krb5-server-ldap
packages before updating the system, for example:
# yum remove krb5-server.i686 krb5-server-ldap.i686If you are installing the update on a system on which you have previously installed the Oracle-supported OFED packages, see the following sections for instructions on how to update these packages during the upgrade:
Section 4.2.1, “Installing Oracle Linux 7 Update 2 from ULN if the Oracle-Supported OFED Packages Are Already Installed” for instructions on how to install the update from ULN.
Section 4.2.2, “Installing Oracle Linux 7 Update 2 from Public Yum if the Oracle-Supported OFED Packages Are Already Installed” for instructions on how to install the update from Public Yum.
UEK R3 is the default boot kernel for fresh installations of Oracle Linux 7.
For systems that are running UEK R3 and are subscribed to the ol7_x86_64_UEKR3
channel on ULN, or the ol7_x86_64_UEKR3 repository on Oracle Public Yum,
you upgrade to the latest UEK release as follows:
Upgrade all packages on the system, including kernel packages.
# yum updateBy default, the boot manager automatically enables the most recent kernel version so you do not need to change your GRUB configuration.
Reboot the system.
# systemctl rebootIt is possible to upgrade an Oracle Linux 6 system to Oracle Linux 7 Update 2 under the following conditions:
The system meets the minimum installation requirements for Oracle Linux 7 as described in Section 1.1, “System Requirements”.
The Oracle Linux 6 system has been completely updated from the
ol6_x86_64_latest channel or ol6_latest
repository.
UEK R3 has been installed on the system to be upgraded and is the default boot kernel. Upgrading from UEK R2 is not supported.
No Oracle product stack is present on the system.
Upgrading is supported only for systems that are installed with the Minimal Install base environment.
The following table shows the changes that are applied to any kernels that are configured on the system being upgraded.
|
Kernel on Original System |
Kernel on Upgraded System |
|---|---|
|
RHCK (2.6.32) |
RHCK (3.10.0) for Oracle Linux 7 is installed. RHCK (2.6.32) is removed. |
|
UEK R3 (3.8.13) |
UEK R3 (3.8.13) for Oracle Linux 7 is installed and made the default boot kernel. The previous version of UEK R3 is removed. |
For instructions on how to perform an upgrade, see Upgrading an Oracle Linux System in the Oracle Linux 7 Installation Guide.
The following sections describe how to install or upgrade the OFED packages provided by
Oracle, including how to replace the default OFED packages from Red Hat that are present on
a system that you have upgraded to Oracle Linux 7 or that you have installed from the Oracle
Linux 7 full installation DVD image, the ol7_x86_64_latest channel on
ULN, or the ol7_latest repository on Oracle Public Yum.
This procedure assumes that you have registered the system with ULN. See Registering an Oracle Linux 6 or Oracle Linux 7 System.
To install Update 2 from ULN on an Oracle Linux 7 system on which the Oracle-supported OFED packages are already present:
Subscribe the system to the ol7_x86_64_optional_latest,
ol7_x86_64_UEKR3_OFED20, ol7_x86_64_UEKR3, and
ol7_x86_64_latest channels on ULN. (By default, the
ol7_x86_64_UEKR3 and ol7_x86_64_latest
channels are enabled when you register an Oracle Linux 7 system with ULN.)
