Goodbye SUNW , hello JAVA . Sun changes its Stock Symbol
2007-08-24 22:34:00 It was this morning that Jonathan Schwartz announced the change of the stock symbol that Sun held for 25 years or so.

Optimizing Oracle Database
2007-08-02 16:52:00 To help your database run faster and more effectively, Oracle has whats called a KEEP pool. Some may call it simply cache that holds most frequently used objects in memory for immediate usage. Description from the Oracle Documentation: “A good candidate for a segment to put into the KEEP pool is a segment that is smaller than 10% of the size of the DEFAULT buffer pool and has incurred at least 1% of the total I/Os in the system” Which means that it is not meant to hold all of your highly demanded tables , just smaller ones. You may want to use some script to handle this task for you, i have found this site that provides a helpful Script that maybe automated if put as a job (on daily basis). www.dba-oracle.com/t_script_automate_keep _pool_tables_indexes.htmRead more...

Oracle - PL/SQL - using WHEN in a trigger
2007-07-06 17:44:00 I've had a bit of trouble trying to decode what Invalid relational operator means when i am using a normal sign <> (which means not equal) which is perfectly valid. Silly Oracle enjoys confusing US, the developers. So after searching Safari and googling furiously i found a good old Oreilly book (even for my version of Oracle 8i) The error happened to be nothing but a COLON that should not be there in WHEN statement. Remember the :OLD and :NEW , it should be just OLD and NEW. Here is the sample: CREATE OR REPLACE TRIGGER emp_before_ins_t BEFORE INSERT ON employee FOR EACH ROW WHEN (NEW.mgr is null)BEGIN IF (:NEW.sal > 800) THEN :NEW.sal := 850; END IF;END; I found a great number of usual problems with Triggers here: http://www.oreilly.com/catalog/ordevworkb ook/chapter/ch16p.html and after searching the solution i found it here: http://www.oreilly.com/catalog/ordevworkb ook/chapter/ch16s.html Read more...

How to find more information on a arbitrary constraint name such as
2007-05-03 17:27:00 Oracle usually stores constraints using this format: SYS_C001457 The number obviously does not make any sense to a human being so here is how you would find which table and which column does this Constraint refer to: select table_name,constraint_name,column_name from user_cons_columns where constraint_name like '%1457%'; Definitely works starting from 8i, haven't tested against 7 and below.Read more...

Where on earth does NetBeans keep it's Library Manager records
2007-04-29 20:00:00 IDEs have their own little world within our system (OS) and the more advanced they are, the harder it is to migrate them to a e.g. new computer with existing IDE (same one) but moving plugins , libraries ,etc proved to be far from easy. Unfortunately i have learned the hard way. I am using NetBeans 5.5 which is quite similar in it's setup to NB 5.0 Over the time i have installed many plugins and created many libraries for my development and ease of use. FYI, Library manager is a neat tool to organize many JAR files (libraries) into groups and give them a name, e.g. Jfree would have many Jar files together with it so when you are developing, you can have a reference to all of these libs by using an alias (Group name). I thought that copying the whole folder e.g. netbeans5.5 would be enough but it wasn't , even though modules are kept in it , the configuration files for modules didn't seem to be there. Same goes for Library Manager Everything is kept in your $H... More About: Earth , Keep , Here

New upcoming Solaris 10 upgrade 4
2007-04-19 22:03:00 I've been invited to join a new beta program since i used to be a beta tester of first betas of Solaris 10 and now Sun is looking for beta testers again to test the new releases.

Buggy MSN Live
2007-04-07 00:11:00 Anyone would simply die laughing when seeing this. If you are a MSN user , you probably have been bombarded every time with a message that a new version of MSN came out, and at some point you will give in and install that version. What i really hated about MSN Live : - The MSN team definitely did not do it's homework in migration My groups were disordered and old ones appeared once again that i deleted years ago. I have no idea where it came from, even old contact that i banned or deleted. It was a MESS i tell you. - These pesky message regarding approval of someone seeing my profile updated? The whole notion is strange, i could care less of it. And the best part, when i clicked on Pending Requests , i got this popup window that contained a few profiles that somehow ( for them) requested my approval on updates. I decided to see who the person is and clicked on the View Profile that was supposed to show me some icon and quick info and this is what i got: Read more... More About: Bugg

Sun's Project Black box - virtualized data center , on wheels?
2007-03-29 17:17:00 It may look like a container with a nice design, not just a coloured box but from the looks of it, it is a sticker with a huge Sun logo on it. Well after all it is still a Shipping container, but what of it? It seems and feels that this would be how data centers will be in the next decade. An efficient monster that will support all of the IT needs for a given sector. It is stuffed with the latest servers that not only super fast but also energy efficient which became a new race among IBM, HP, SUN hardware creators. But SUN surprised them all, now you could take your Data Cent er on wheels and move it to your garage :)) Well , no, you won't unless you have a backbone running towards your house and a nice little power generator. But companies might benefit from this project. Let's have a look at what this "container" has in stock for us? Read On, you will be shocked. Read more... More About: Project , Black , Virtual
Saving a database an extra round trip, update when needed
2007-03-26 20:20:00 Before even begin, if your project deals with a database directly without any Hibernate or ORM like software this is for you. Also it is important to note that ViewState must be enabled on the page we're about to change. ViewState in short terms a hidden encrypted input field on your page essentially. What's it useful for? If you are making some sort of changes to e.g. Drop Down List or a Calendar, you might want to know if a certain field has been changed by a user. E.g. A user selected a different value in the Drop Down List, hence upon hitting a button "Update " your code would know that drop down list has changed its Index. How? 1. To store an initial value of component (e.g. Drop down list) , you should do like this: if (!IsPostBack) { ViewState["ddlindex"] = this.ddlSomething.SelectedIndex; } 2. Upon updating simply check the ViewState for that id, if the information in the ViewState is different then the current one, you should update, other... More About: Data , Database , Trip , When

How do you manage various containers?
2007-03-24 04:18:00 I usually develop on Sun Application Server which comes with SDK and Netbeans in a bundle, but unfortunately i don't have the luxury of running a Sun App Server on my host so i have to redeploy on Jboss to see how it goes.

But do you manage deployment, undeploy and other operations, since each one is totally different from each other. I found an interesting project: Cargo cargo.codehaus.org/HomeRead more...

Properly closing Database Connection C# way
More articles from this author:2007-03-07 19:28:00 Most of us , developers, are quite a lazy bunch, well aren't we all? How do you close and dispose your database connection objects? I have a seen a lot of developers do this: try{ this.cmd.Connection .Close(); this.cmd.Connection.dispose(); }catch{ } Not only can this throw an exception which obviously will be caught but it simply tells CLR to do more job than a simple check if object is null or not and if not wheather it is Open or not.
