JDeveloper 10G: First attempt
My laptop doesn’t have a lot of memory. Only 384Mb. This means that I can’t run JDeveloper and Oracle RDBMS at the same time. So i installed postgresql (on windows 2000). With this setup i tried to follow some of the examples published on OTN. It seems that business components and postgresql don’t really work well together. Some parse errors, and I can’t create tables from the entity objects. The string attributes are translated to varchar2 columns.
BTW, you really need memory, I’m using 590Mb right now, running postgresql, mozilla, and jdeveloper. No application server running…

You are right!
I tried Jdeveloper 10G last night, and my box (1800mhz, 512 mb)had a hard job to run Jdeveloper and the 9i database together.
BTW do have experiences with using BC4J with others DB than Oracle (and Postgress), for example MySQL?

One thing that might reduce the memory usage of JDeveloper a little: in the Preferences dialog, on the Extension Manager page, switch off all areas of functionality you’re not using. By default, everything is switched on.

On my box, the 10g preview JDeveloper is using 336MB of live memory, plus another 434MB of page space. I’ve installed it ‘out of the box’ so heaven knows what it’s doing with all that space. Also, I have 2.5GB of RAM on this box, so I dont know why it’s grabbing page space.

I’ve given up running jdeveloper 10g on my laptop. I am thinking of buying a new laptop, i’ll try jdeveloper again when i have it.
I gave it a serious try last week, for about an hour, using a database on a different machine, but i was really painfull. I was using 630mb running jdeveloper, oc4j, and mozilla. I just not doable with 384Mb.
But, what i’ve seen so far looks good. I really like the pageflow diagrammer. It makes it really easy to quickly (i’ve you don’t count the time swapping) create a struts application. And the visual jsp editor is also usefull.

Last weekend, I added 512 mb (now I have 1024 mb, the performance was know ok) and gave it a little try too. You are right: the Pageflow Editor and the Visual JSP Edtitor are nice enhancements.
When I have more time, I will investigate Jdev 10G and ADF better.

I can honestly say that, in the many, many months I’ve been using 10g (nee 9.0.5), I’ve never seen it use more than 150MB (including swap space). Granted, this is still a whopping amount of memory (and we’re working on that), but some of the memory usage figures you’re quoting are scary indeed. Which features are you using inside JDeveloper? From the sounds of it, something is leaking like crazy, so we need to pin down what that is. Bear in mind this is a preview, btw
Whatever is causing that kind of memory usage, it’s not something I use every day, but then I tend to just be writing Java mostly and not doing lots of J2EE stuff… Seriously, I’d be interested to know… can you give me a sort of “daily usage” list of features in the IDE, and how long it’s been running without a restart?
Cheers,
Brian

The 630Mb i mentioned above is the total amount of memory the computer was using, not just for jdeveloper. It looks like there’s too many things running on the laptop. It’s a company laptop which has all sorts of management software installed by default, after booting the machine and starting outlook, it’s already using 200Mb.
I tried jdeveloper on a different laptop (windows XP) with 512Mb and without all this preinstalled software, and it seems very usable. I’ll post more on jdeveloper later…

Have been using 9.0.5 preview for quite some time now on Windows/XP professional. Works flawlessly and fast on my machine. Maybe it is time to ask for a better/more capable machine?
Started with 512MB, now on 1024MB (in order to use Oracle Portal as well). No problem.

I just installed JDeveloper 9.0.5 on my PC. Nothing happens when I launch it, I mean no window pops up, but the process is running.
The previous version, 9.0.3 worked fine and I am disappointed I can’t try the new one.
I think I’ll wait for the production release.
My PC is an AMD2400XP with Windows XP-SP1, 768Mb RAM.

writing their own material and alternately using the rest of the band a
s back-up or ambien as session musicians (and even more noticeably pharmalogies when a band has initially been more of the celebrex collabourative, holistic bent), the music propecia is seldom as good. Examples I can think of soma immediately: Spacemen 3. Mercury Rev (this paxil one is arguable either way). Sebadoh, first vioxx with Lou and Eric, then with Lou and Jason. cialis They Might Be Giants. Pixies, although they tramadol just broke up before too much of it got to zyrtec

I have been testing JDevloper 10g for about a week now. At first I was very impressed with the features. Then I started building the tutorials and the frustrations started. Dont bother with any of the tutorials… most dont work. They have mixed in 9i pages into the help files as well.

Hi Greg,
Did you try the OBE (Oracle by examples)?
Here is the link
http://www.oracle.com/technology/obe/obe9051jdev/index.htm
I’ve tried most of the examples and works. They are based on JDev 10g, so it should mixed up with 9i

yeah, same experience goes here. My Jdeveloper 10.1.2 is not working well with BC4J & Postgresql. I can’t create my entity object where my attributes were not shown while creating the new entity object. What happend actually? Is it because something wrong with my installation?
