Short post to mention that I’ve added another installation cookbook to the set published here. This one falls into the Advanced Cookbook section and covers installation on Oracle Linux 6.3 with Oracle 11.2.0.3 single-instance and 4k ASM, paying special attention to the configuration of UDEV and the multipathing software.
The blog posts haven’t been coming thick and fast recently as I have been concentrating on Violin’s (excellent) end of year but I hope to resume soon. I have one more piece to publish concerning subjects like Exadata and VMware, then a new blog series on “Storage for DBAs” to mark the combined anniversaries of my joining Violin and starting this blog.
In the meantime I’d like to recommend this short but very interesting blog series on Exadata Hybrid Columnar Compression over at ofirm.wordpress.com – part one starts here…

Only one so far but the menu will grow…
