Quick post: I was trying to connect to a 64-bit Oracle database using PL/SQL Developer. Despite ORACLE_HOME being set the right values and oci.dll available, PL/SQL Developer could not connect to the database.
By default, Oracle Forms Application Server serves Oracle Forms applications using the built-in Jinitiator JVM. While JVM works swell with cutting edge browsers1 it pretty much crashes most of the other browsers2 and doesn’t work at all in Chrome. There are workarounds but the workarounds do not play well while working with multiple tabs.
Steven Feuerstein has a nice little presentation on some golden rules for developers. They aren’t anything new, yet not many people read/follow them 🙂

Toad (acronym for Tool for Oracle Application Developers) is arguably one of the most popular and best known tools used by most people dabbling in Oracle databases ( or for that matter, most relational databases anyway). Toad’s reputation is so good, I’ve known few people swear by it and don’t even bother looking at other software, no matter how good.
Toad’s got more features than your average SQL/ PL/SQL developer would use,and hence got a bit of a steep learning curve. Not to mention an even steeper price tag ( the base edition starts at $957, and goes all the way upto $4709 if you include the Code Tester and DB Admin module). Given these prices, Toad is pretty heavily pirated.
However, most people are unaware that Toad also comes in a freeware edition, and until recently was severely crippled. Few days ago, there was an update to Toad freeware – and the updates are pretty good. The freeware edition is now based on 10.5 codebase, rather than previous 8.5 codebase. Now before you start jumping up and down, the restrictions on the freeware edition are still in place, but noticeably lesser than the previous update. Some of the restrictions include you being limited to only one concurrent database connection (which btw – would severely hamper me, I generally maintain 2-3 connections). Another major irritation is that the freeware edition will expire every 90 days, and you will need to uninstall, re-download and reinstall it. Ugh.
Here’s comparison chart between the commercial edition and freeware.
If you’re OK with the restrictions imposed by freeware edition or a Toad fan, then you can go ahead with getting it. If you ask me, Oracle’s SQL Developer is a perfectly acceptable alternative tool.
(In case you’re wondering my preferred tool, its Allround Automations’ PL/SQL Developer. Yes, yes, I know, the UI is butt ugly – I didn’t want to touch it at all just because of the UI – but believe me, once you get over the UI, you’ll love it – its fantastically fast, consumes very little memory and got boat load of features for the price its available at. I’ll probably do a review of the tool soon.)
Do let me know if you have a preferred /alternative tool that I could look at.
If you’re looking to brush up on your PL/SQL knowledge, PL/SQL challenge is pretty nice. It’s a daily challenge quiz, where you are presented with multiple choice or true/false questions. It’s an initiative by Steven Feuerstein , who’s pretty well known. I just joined in, first few questions were not too tough 🙂 Join in, there’s some great prizes to be won .
If you know of any more such websites, do drop in a comment and let me know.
(PS: If you’re wondering what’s with the weird URL structure, well its built on Oracle Apex. Long, clumsy URLs are a pain, and Apex does nothing to banish them).
They say “Necessity is the Power of Invention” – a quote which I fully understood the impact today. I’ve been trying to understand Oracle’s Hierarchical Queries for a while now, but never fully understood the situation under which or when it would be used. Yesterday I got a reason to use it. Let me begin.
