CentOS and Oracle release their Red Hat 6.2 clones
Dec. 20, 2011

A week after releasing CentOS 6.1, the CentOS project launched version 6.2 of the Red Hat Enterprise Linux (RHEL) clone, while Oracle released its own RHEL 6.2 variant with Oracle Linux 6.2. Meanwhile, Red Hat unveiled a beta of RHEL 5.8, and announced strong third-quarter earnings.

The CentOS project released CentOS 6.2 only a week after it unveiled CentOS 6.1. The CentOS 6.2 release reverses the community project's slow upgrade pace, as it now trails its RHEL 6.2 foundation by only two weeks.

The freely available CentOS 6.2 offers almost all the non-proprietary portions of RHEL 6.2, and is said to be 100 percent binary compatible. The distribution is available for i386 and x86_64 architectures.

Meanwhile, Oracle released its own Red Hat clone with Oracle Linux 6.2, which adds its Unbreakable Enterprise Kernel to the RHEL 6.2 codebase. The kernel, which is optimized for performance on Oracle software, is claimed by Oracle to be faster than a standard RHEL kernel in operations ranging from OLTP to Infiniband messaging.

The underlyling RHEL 6.2 upgrade introduced some fairly significant performance and scalability enhancements on multicore platforms. Improvements were said to have been applied to resource management, high availability, storage and file system, and identity management components, among other enhancements.

On Dec. 16, Red Hat announced a beta version of its long lifecycle RHEL 5.8 version. The new version supplies a wide variety of updates and new hardware support, and offers a special focus on power, security management, and virtualization enhancements, says Red Hat.

Finally, on Dec. 19, Red Hat released its fiscal 3Q 2011 earnings, showing another quarter of positive earnings. Profits rose to $38.2 million, or $0.19 per share, up from $26 million, or $0.13 per share, in 3Q 2010.
