Getting your Oracle Forum posts as RSS
In my last post I said one of my "Top 10" wishes for OTN was to be able to get an RSS feed of posts by a specified member to the Oracle Forums.
At first it may sound a bit narcissistic to have a feed that allows you to follow what you have written yourself! 
It was my exploration of Jaiku that prompted the thought. Since "presence" is their big thing, I've been experimenting to see what's its like to have Jaiku aggregate all your web activity. So far it looks really cool - I love the interface. Must say that I'm not sure how useful Jaiku may turn out to be in the long run ... I suspect it works best if you have a whole lot of your friends also using it. NB: the Jaiku guys are particularly focused on mobile phones. Its not something I've tried yet because I think it would be a bit ex from where I live.
So Jaiku was the catalyst for me thinking about getting an RSS feed of my forum posts. Recently I've been trying to make an extra effort to contribute to the forums; frankly, they've always seemed a little quieter than I think they should be. So seeing any forums posts I make highlighted on Jaiku should be one of the neat indicators of my "web presence".
Problem is, while you can get a web page that lists your recent posts, and you can subscribe for email alerts when authors post, I wasn't able to find a way of getting an RSS feed for a specific author's posts.
So I created a little perl script that scrapes the HTML and generates an RSS feed (using XML::RSS::SimpleGen). I've packaged it as a CGI program on a server I have access to. That's what I registered on my experimental Jaiku site, and it works like a charm.
Until Oracle build this feature into the forums, feel free to take my oracleForumRSS.pl script and experiment away. Its pretty basic, but is generic for any forum user and ready to go. Sorry, but I'm not hosting it for direct use by others, so you'd have to find you own server with cgi or convert it to script that spits out a static rss xml page instead.
Post-script: Eddie Awad blogged on the "Easy Way" to do this using Dapper. Very cool, thanks Eddie!

OTN Semantic Web - first look
My last post on the state of the OTN community was probably a little long on rhetoric. So I thought since the move of Oracle Blogs! to the much vaunted Semantic Web seems well underway, it would be worth taking a first look. The old site has taken a bit of stick for being, let's say, less than engaging.
The big improvement by using the Semantic Web is of course all the slicing and dicing it allows to hone in on posts of interest, with the blogger tag cloud giving instant feedback (and access) to the bloggers most active on a given subject.
I got to say though it doesn't take long before you realise this site needs a serious design and usability facelift. Urgently!
Maybe its easy to be critical with something new. Actually, no "maybe" about it...
OK, I won't nitpick too much. The biggest problem is that we've paid for all the slice & dice flexibility in the worst possible way ... all the content has been squeezed off the page!
If Oracle do nothing else, they should push all the filtering and clouds out of the way to make a nice, big section of the page available for the star of the show - the content. Use AJAX to make all the filtering available in an instant, but avoid the clutter. At that point, we have a decent replacement for the old blog site.
But for OTN to truely find its Web 2.0 mojo, I think the Semantic Web is probably laying some important foundations but its just the beginning.
My Top 10 OTN/Semantic Web Wishlist
OK, so quick brainstorm, and here's a selection of things I'd really love to see happen on OTN:
- Take Down This Wall ... between content types (not what Justin originally meant, I know)! The current layout of the Semantic Web page puts concrete delineation between content types (podcast, blogs, forums and other personally attributed content) at the top of the page. At first that may sound fine, but its locking us into a mindset and behaviour patterns that assume these are all distinct in terms of production and consumption. A destructive and divisive fallacy. Get rid of it, and make the content type just another filter.
- Long live the forums! These are places where you can actually have a conversation (instead of trying to have a conversation in blog comments). OK, so they look a bit dated, and the level of participation can be a problem. Nothing a lick'a paint can't fix, and use the Semantic Web to drive usage.
- Give Oracle's "celebrity" bloggers a personal forum that links neatly off their blog so that conversations can be usefully launched on the back of a blog post. What the heck, let everyone have a personal forum!
- Let me take an RSS feed of my forum post history. Its the kind of thing I'd put on my Jaiku page. At the moment, we can just watch via email.
- Let me take an RSS feed of any Semantic Web page I find/define (with all the current filtering etc).
- Drop the barriers to participation. The Semantic Web makes concerns of the "quality" of bloggers irrelevent. If they never post, they get buried. OTN registration should include an opt-in for an Oracle-host blog, or a link to an externally hosted blog.
- An OTN Community Site Badge. To promote participation, how about a logo/widget/javascripty thing that bloggers can put on their blog? It would both brand their blog as part of the OTN community, and also provide a link back to the OTN Semantic Web. It would be neat if it actually had a function (like clustermaps), but I can't think of anything useful right now.
- Invert the Semantic Web. OK, we're getting used to coming top down. But what if I *start* from someone's blog post? It could be a really neat thing to be able to then explore the Semantic Web from that point out ... to discover related or linked pages. Worth an experiment I think.
- Drop the dopomene theme. I'm in the Semantic Web, discovering fascinating information in ways that have never been possible before. This is really exciting! ... but the look and feel is blaring a very incongruous message that messes with your psyche. We need a better use of colour and graphics.
- ... and a dozen other insanely cool Web 2.0 things that I can't even imagine right now, and if I could I'd be well on my way to my first $1b.
Wow, I'm actually getting excited now...

No respect! Should Justin care?
Justin "Dangerfield" Kestelyn launched one of the most lively discussions the Oracle community has ever had with his "I Don't Get It" post some weeks back.
"In particular," he states, "Oracle gets zero credit in this community for its rather aggressive support of blogging (by employees and nonemployees), despite the fact that a rather large blogging community exists and has for some time"
Strangely, there seems to be pretty unanimous agreement that there is a large number of bloggers out there, and some very good ones at that. Vincent McBurney's blog made special mention of Nishant Kaushik, Rob Smythe and Steven Chan for example.
And if we also consider the OTN Podcasts (my favourites being the ones that feature interviews with the "names" like Tom Kyte and Wim Coekaerts), it seems to me pretty evident that we actually have a pretty healthy community of content creators.
But when I look back at what Justin actually said, he was referring specifically to the lack of credit from the Web 2.0 community.
I think the OTN team - and Justin in particular - have been doing a fantastic job with the blogsphere and podcasts. But is that enough to make a stir in the Web 2.0 scene? Maybe a year or two ago it would have, but not any more. Sadly (for Justin) it is now just all too routine.
How many "Web 2.0 firsts" can OTN really claim? The harsh reality is that to make a splash and get some respect in the Web 2.0 community, Oracle needs to do much much more. And I don't think its about content or whether our blog etiquette is any good. Leadership and innovation is the name of the game in two important areas:
- How to build more effective social networks and find new and better ways for this to deliver real benefit to the community. At present, I'm not sure we even deserve the "community" moniker .. it feels more like a public swimming pool we all just happen to go to, rather than a forum (in the Roman sense) where we meet, discuss and debate.
- Invent and apply cutting-edge Web 2.0 techniques and technologies to support this goal. Yes, this IS about technology;) The Web 2.0 community is incredibly dynamic and creative at this point. Take blogs for example. They've been around for a while. Long enough for people to discover that for some things they are really good, but in other ways they suck (like trying to have a "conversation" in comments). So we now have sites like twitter, tumblr, virb and jaiku all experimenting with different approaches and trying to push the envelope in meaningful ways. Its this kind of creative experiementation that we haven't seen Oracle doing in the past ... with the one recent exception being the semantic web (hopefully an indicator of more great things to come). If Oracle really wants Web 2.0 street cred, OTN should be the playground where it is seen to be exploring the outer limits of what is possible - some of which may find its way back into the Fusion Middleware product line.
One notion we must definitely reject is that somehow we need to coach all the Oracle bloggers into becoming Web Celebs. To do so totally ignores (and destroys) the value of diversity in the community. Personally, I identify five "kinds" of web presence we should embrace:
- Leadership and Product Management as a "conversation". These are the celebs and thought leaders engaging with the community, but very much with their corporate responsibility at the fore. Funny thing is, I had the impression Oracle was doing much better in this regard, but it doesn't hold up to inspection. Mark Wilcox is one of the few getting close. Perhaps commercial considerations actually make it a very hard thing to do without tipping the competition too much, or just sounding like a mouthpiece for marketing.
- Web 2.0 as Shared Memory. I think one of the completely understated revolutions going on. As I've blogged before, and epitomised by the likes of Alejandro Vargas, this is all about using the web to finally Get Knowledge Management Right. These tend to be boring as hell to try and follow unless they are right in your niche. Scenario: One day, you'll be sweating a problem. Ask google, and thank your lucky stars that there are people around like Alejandro.
- Living your professional life online. Probably the most common approach today on OTN. Its a diary, scrapbook and log. You may find some really good gems, but there's no harm in being obscure in this category... you're just one of the community and its often done more for your own personal benefit.
- The personal/social presence. And yes there is room for all those who are part of the community (because they work at Oracle for example) but just want to talk about baseball!
- The audience. Let's not forget the vast majority of people who are searching and reading, but will never do much more that perhaps post a question to a forum or maybe a comment on a blog. For a whole range of reasons there's no value or motivation for them to go further. Don't try and make them blog. It won't work. But should we do everything possible to make sure they are well served by the community ... yes!! Numerically, they ARE the community.
Justin finished his initial post with a somewhat flippant "...maybe I shouldn't even care!". But perhaps he unwittingly hit the nail on the head.
It's a truism in business that if you forget who your customers are, you are doomed. Similarly, if OTN becomes preoccupied with impressing the Web 2.0 community as its primary mission, I'm pretty sure they will find success "inexplicably" elusive (and prove that all of Justin's denials of it being a PR conspiracy are lies!!).
Success will come most easily if OTN focuses on serving its real constituency first - the Oracle community of employees, users and developers. Do that well, and if OTN is indeed pushing the boundaries, then the Web 2.0 cred will be the just reward.
I guess in a way its like being cool. Try to be cool and you'll fail. You just are (or not, as the case may be).

Do Oracle temp tables behave correctly under DBI?
Andon Tschauschev recently posted on perl.dbi.users concerning an apparent problem with temp tables "disappearing" between statements in the same session. He was using SQL Server via ODBC support.
The discussion and investigation continues, but it made me think to test if there's any similar strange behaviour with Oracle via DBI.
The temporary table model is somewhat different in Oracle, and centers around the "CREATE GLOBAL TEMPORARY TABLE.." statement. Temp table definitions are always global, but data is always private to the session, and whether data persists over a commit depends on whether the qualification "on commit preserve rows" or "on commit delete rows" is specified.
testOraTempTables.pl is a simple test script to check out the behaviour. Good news is that all seems to be a-ok. The temporary table definition is persistent across sessions, but data is not, and importantly (..the point of Andon's investigation..) data is preserved across DBI calls within the same session as expected.
Sample output from the test program:
C:\MyDocs\Testers2\perl\dbi>perl testOraTempTables.pl orcl scott tiger
[1st connection] connect to orcl {AutoCommit => 1}:
[1st connection] create global temp table:
create global temporary table t1 (x varchar2(10)) on commit preserve rows
[1st connection] insert 3 rows of data into it: insert into t1 values (?)
[1st connection] should be 3 rows because we have "on commit preserve rows" set:
select count(*) from t1 = 3
[2nd connection] connect to orcl:
[2nd connection] should be 0 rows because while the table definition is shared, the data is not:
select count(*) from t1 = 0
[2nd connection] disconnect:
[1st connection] disconnect:
[1st connection] reconnect {AutoCommit => 0}:
[1st connection] should be 0 rows because this is a new session:
select count(*) from t1 = 0
[1st connection] drop the temp table: drop table t1
[1st connection] create global temp table:
create global temporary table t1 (x varchar2(10)) on commit delete rows
[1st connection] insert 3 rows of data into it: insert into t1 values (?)
[1st connection] should be 3 rows because we have autocommit off and not committed yet:
select count(*) from t1 = 3
[1st connection] should be 0 rows because now we have committed:
select count(*) from t1 = 0
[1st connection] disconnect:
[1st connection] reconnect {AutoCommit => 1}:
[1st connection] insert 3 rows of data into it: insert into t1 values (?)
[1st connection] should be 0 rows because we have autocommit on and "on commit delete rows" defined:
select count(*) from t1 = 0
[1st connection] disconnect:
[1st connection] reconnect {AutoCommit => 0}:
[1st connection] drop the temp table: drop table t1
[1st connection] disconnect:
