Oracle: Unbreak my Linux Heart

Not we are using this anywhere or in production, but it is useful to know that ext4 file system support is coming soon. Kernel 2.6.24+ adds experimental support already, so you're able to test with it. IBM has a little write up about migrating to ext4 ... which is surprisingly simple!

Linux has a wealth of file systems to choose from, but we are facing a number of challenges with scaling to the large storage subsystems that are becoming common in today's data centers. File systems need to scale in their ability to address and manage large storage, and also in their ability to detect, repair and tolerate errors in the data stored on disk. So Oracle is creating a new file system: btrfs. Read more...

Last year, the Enterprise OpenSource Magazine website posted results of a performance study of several open source clustering file systems. The study was done in an academic environment and aimed to measure the same workloads on several different technologies. However, for the purposes of this blog, the difference between Red Hat's GFS and Oracle's OCFS2 are most interesting... Source: Kevin Closson

Sadly but expectedly, Oracle does not provide or support the Red Hat Application Stack . The stack enables easy development of web applications because its components are fixed. The stack includes JBoss, Hibernate, Red Hat GFS, Red Hat Cluster Suite, and Red Hat Directory Server. However, Oracle already bundles its own "stack" with Apache and Tomcat in the form of the Oracle Application Server . Oracle has made, what appears to be, its own fork of these open source software packages, and it support them independently of the public versions of Apache and Tomcat. For clustering applications, Oracle also delivers its own file system OCFS2.
