I was looking for something on google groups last night and came across a post by Mladen that included a link to his website. As I did not remember him having a site I went for a look. Mladen's site
is Mladens home page and it looks quite new. Mladen is writing a book about Oracle and PHP. I found a couple of links on his page that looked interesting. The first is about Direct I/O
which I have skimmed over but it looks quite interesting. The second I was more interested in as its about an undocumented utility oradebug
. I am always interested in undocumented Oracle. This is not a bad paper, most of the ground is covered in other papers listed on my undocumented Oracle page
but its still a good paper. The paper starts with some discussion of what oradebug is and how it works and what other information is available. Mladen goes on to cover starting orabdebug, attaching to an Oracle process, taking dumps, setting events, suspending and resuming and hang analysis.
I have updated my Undocumented Oracle page
to include details of this paper.
