First of all, if you are using NFS to store Oracle database data files, I strongly advise you to enable Oracle Direct NFS (DNFS) to access these files. However, if you are not using NFS, DNFS is probably not of interest to you, and you should stop reading here. But, if you want to set it up, let’s go!
A while ago, I was paged by a client having backup job failure. Doing my routine as usual, I started the investigation by looking at the job execution log. Connected to the box was a strange output. Here it is!
Sharing knowledge not only is beneficial to others, but also enhances one’s own knowledge and broadens the spectrum. Blogging is all about sharing and this Log Buffer Edition brings together some great blog posts from around the database arena.

But I needed a way to easily serialize my objects for it. So I dragged in MooseX::Storage to the mix. And then I had fun with helper classes and roles to make the interfacing between the two systems as smooth and slick as a buttered piglet.
With the rapid advancement in the database technologies, the legacy systems are either being upgraded or replaced. Or, in some cases, technologists are finding ways to support them in new ways, showing us the flexible nature of databases and the belief of professionals that the sky is the limit. For this Log Buffer Edition, we go even beyond.
A new trial version of DBD::Oracle has been churned out. This release is mostly about Martin J. Evans going all ninjawesome on minor bug fixes as well as paving the way for an upcoming refactoring/speed boost of ora_verbose. As usual, the new version will be soaked for at least 2 weeks before it will turn into its fit-for-general-consumption v1.46 incarnation. Testers, please give this baby a whirl. The full changelog follows for the curious-minded.
