Thank you, it helps! Since we use FOR FETCH ONLY or FOR READ ONLY we did not heard of locking problems anymore. Thanks again!
Hi,

In the J2EE project I work now we are using DB2 databases and we interact with them through DB Visualizer 4.1, with auto-commit set to true. Third parties in the project said that we are causing tables locking problems due to the fact that we are using DB Visualizer. They say we should use the command line (db2 console prompt) or command editor, provided by IBM with the installation of DB2 client. But I think these are too rudimentary. Also, they said that a team member in our team has definitively locked a table with a simple select and that their database admin has to manually type some commands in an administration tool to release the lock!! I do not think that DB Visualizer is that dummy and that it does not make locking management by itself!


That is why I think that the real problem is that the database is not well configured, but before checking that with them, I would like to know if possible, if anyone experienced locking issues in a team due to use of DB Visualizer (in particular DB Visualizer 4.1)?
Hi, can you help me with a link with RAD 7.0 benefits and /or known issues? Do they have something specified for the version they are releasing?

Seems to me from the logs that you only have allocated for your WAS server a maximum of 256 Mb (), which I know is quite a problem for the memory WAS server uses, since I know it needs 512Mb allocated (at least) to work properly. You can increase memory allocated from the *.ini file of the server.

And I forgot: yes, design patterns are still between exam objectives. This book: Addison Wesley - Gamma, Helm, Johnson, Vlissides - Design Patterns, Elements Of Reusable Object Oriented Software is recommended by Sun, another book that can help you with design patterns is "Head First Design patterns", contains a lot of examples and it's written in a more readable format.
it's a very bad practice to access database data directly from JSP. It's against all patterns.

But if you really have to do this, you can use Spring framework (it is easy to integrate). In your JSP you can write java code as scriptlet using <%..%> statements. So here you could write directly database access statements. But, I repeat, this is against DAO pattern (you can check Sun's reccommendations at: how Sun describe DAO pattern)

What you want to do sounds to me like hackering tentative ...

Hi, it is because of browser, not because operating systems. Some browsers require you to close all opened tags. So, in your JSP you have a not closed html:select tag. Firefox recognizes your pages even if you do not close all your tags, but MIE shows also an error when you have some not closed tag. I hope this helps a bit.

I also have experienced problems like the one you mentioned, but only when "Build automatically" option is not enabled. IBM says on its site that in RAD to optimally delete deployed code and deploy ejb projects you need to have "Build automatically...." option enabled all the time. That really helped and since I enabled it I didn't had problems anymore.

Hello,

I have browsed topics here and also another forums on the net and I saw a lot of topics regarding part II related to airline flight reservations. I am preparing for SCEA exam and I would like to know if there is the same application (tickets reservation) for everyone in part II? Or is it different for every applicant? Thanks!
Hi,

Congratulations, it's an impressive score!
Information you provided is very useful, thanks.

Just a question: what do you mean by "deep reading"? I am trying to estimate the time I need to prepare for first part and I am trying to figure out how much time (approximately) do I have to allocate per day to intensive reading to get a score like yours ?
