Developer on 2000?

I can't start my listener after install.
Does Developer work on Windows 2000?

Installed Developer 2000 on Win2000. It overwrites System files. I lost hardware connections. Called Technical support and got the run-around. If you can use an alternative like Crystal Reports do so.

How i can connect developer 6i & 2000 to databse 10g standerd-one

How i can connect developer 6i & 2000 to databse 10g standerd addition one

I don't think Developer 2000 is supported with 10g, I haven't tried it.
Patch 18 for Forms 6i can only be downloaded from metalink since Forms 6i is no longer supported only limited support for E-Business Suite users.
Why would waht to use Dev 200 and Forms 6i, these product are no longer supported, why no use the latest version of Forms Forms 10g R2???

SQL Server 2005 and 2000

Hello,
Is it possible to develop on SQL server 2000. And use the sbo company database in sql server 2005
Regards,
Kit

Yes Kit,
SQL 2000 is forward compatible with 2005. Thus you can develop in 2000 and migrate to 2005 when need be. The only thing is with the securities in 2005. It works slightly differently in 2005. But that you can sort out with minimal effort when you migrate/implement to 2005. And this will only be an "issue" if you use your own SQL logins/user. Using the standard SBO connections will allow seamless cut-over from 2000 to 2005.

Exchange 2000 portlets time out

Running the exchange ASPs both in an empty browser window and as portlets goes awfully slow. Adding all three portlets to one page makes at least one of them time out, regardless of the timeout setting. Running only one takes up to ten seconds to complete. The ASPs are installed on the same server as is running the Outlook Web Access. When running the OWA's default GUI it completes downloading in a couple of seconds so the server's capacity should not be the issue.
Could this be a problem with the authentication since the ASPs use basic authentication while the OWA uses windows authentication? Anyone have tips on how to speed 'em up?

I will try and explain the implementation of MS Exchange Portlets and inturn try to solve the problem that we have at hand.
Outlook Web Access (OWA), is the default web access utility provided by Microsoft.
The MS Exchange portlets follow the earlier implementations OWA (OWA 5.5). This implementation is with Active Server Pages (ASP) and Collaboration Data Objects (CDO), these in turn rely on Messaging API (MAPI) function calls to retrieve messages from the Exchange Server. For each connected user, OWA must open a MAPI session with the Exchange server, but the number of open MAPI sessions that can be efficiently handled within an ASP session is limited. The architecture restricts the number of users that can simultaneously connect to an Outlook Web Access server.
Because of this, a major complaint that many users had with earlier OWA versions was performance.
Now coming to the implementation of OWA in Exchange 2000, rather than attempt to improve OWA's performance by tweaking the existing code, Microsoft developed OWA 2000 from scratch to take advantage of universal technologies like Web-Dav. In addition to this OWA 2000 uses XML and Dynamic HTML (DHTML) to improve performance and provide additional advanced features by offloading some rendering tasks to the client and reducing the amount of client-to-server communication.
So OWA 2000 will run fine without giving any performance issues. Same would be the case if you use IFrame to use load OWA.
Also contrary to what the OWA 2000 response time suggests, in these Portlets the server capacity would matter.
Information that would prove helpful to investigate this problem further would be;
1. What is the Exchange/IIS Server setup,
a. Are the Exchange/IIS on the same machine?
b. Machine configuration of each of the machines?(OS,RAM, Processor speed etc.)
c. Are the Exchange/IIS on the same Windows domain?
2. Number of users simultaneously accessing MS Exchange through Portlets.
If you can share this information regarding the setup/usage, we can investigate into this problem further, and try to solve the problem.

Is there a flowchart describing gc behaviour of the Sun hotspot jvm?

Given that garbage collector tuning is such an important part of application deployment it is surprising that the behaviour of the garbage collector implemented in the Sun JVM is so poorly documented.
Our system is displaying behaviour changes that we don't expect and do not want and it we can't find enough information to predict how the garbage collector will behave under expected and changing conditions. This makes it impossible to select sensible parameters for our system.
For example, we have included the -Xincgc option when running a weblogic6.0 server to reduce the size of the gc pauses. Monitoring the memory (both on the weblogic console and via -verbose:gc) we have small gcs happening quite frequently but after a couple of hours it switches over to full gcs and stays that way for ever after. The full gcs bring on the longer delays for garbage collection (typically around 5 seconds) every 5 minutes or so.
Incidentally, we assume the small gcs are the incremental gcs performed on the old area but there is no way to distinguish those from the little scavenging gcs that are performed even without -Xincgc.
The total memory used is quite modest (1/4 to 1/2 the size generally) compared to the max heap size and the old area and comparable to the new area.
If there is a flowchart or uml activity diagram that describes the hotspot gc behaviour so that we could be a little more deterministic in our approach to gc tuning I would be most grateful to get access to it. This trial and error approach is very frustrating.
There's some very useful information out there about the structure of the java heap and the meaning of the various options and even the garbage collection algorithms themselves but it is not sufficient to specify the behaviour of the specific hotspot jvm from Sun Microsystems.
I liken it to having a class diagram describing a highly dynamic system but no interaction diagrams.

I would also love to have a comprehensive explanation of garbage collection in Java. I'm still mystified by it in some respects.
The author of this thread has obviously researched Java GC... don't know if this helps, but someone in another thread posted this link to a JDC Tech Tips issue concerning memory allocation and GC:
http://developer.java.sun.com/developer/TechTips/2000/tt1222.html
Also the links near the bottom may be worth checking out...
There's something in that web page that I still don't understand and I think I will post a message about it soon.

Help! Trying to understand overloading.

I keep getting the following compile error when attempting to compile the following code. If I swap the f(String s) with the f(float f) method it works but I don't understand why. Can anyone help this newbie?
MyClass.java:23: reference to f is ambiguous, both method f(int) in Overload and method f(float) in Derived match
          d.f(100);
class Overload {
     public void f(String s) {
          System.out.println(s);
     public void f(int i) {
          System.out.println("" + i);
     public void f(boolean b) {
          System.out.println("" + b);
class Derived extends Overload {
     public void f(float f) {
          System.out.println("" + f);
public class MyClass {
     public static void main(String[] args) {
          Derived d = new Derived();
          d.f("Hello World");
          d.f(10);
          d.f(true);

Multithreaded client issues

I have a multithreaded client that maintains a pool of connections to the Oracle server. Each thread grabs a connection to issue selects, updates and inserts to the DBMS. Under Win 2000, an access violation occurs in msvcrt.dll when the second or third thread exits (during the OS call to _endthreadex). This problem does not occur under WIn NT 4.0.
Are there any multithreaded issues related to development on 2000 vs NT? Where can I read more about writing multithreaded OCI clients in general?
The Win 2000 box is current on Windows 2000 service packs, Visual Studio SPs, and the MS SDK. I'm using OCI V8.
Thanks,
Ben

if your question is the same as another post up in this thread, you just need a single environment handle. OCI will automatically manage the thread safety across multiple threads.

Importing classes/packages

Does importing an entire package cause the classloader to load ALL the classes in that package into memory or are they loaded only on demand?
Suppose package called MyPackage.
import MyPackage.* - Does this cause all the classes to be loaded into memory ?

Here's some more info on the 'import' statement:

Return statement on a void?

Theres a part that i dont understand, and if its possible i'd like to be helped a bit with it ^_^.
This class is part of a program that uses threading to display a consistent "Tick Tock", but the part that i dont get is why is there a return statement on the method that is on bold, isn't void supposed to mean that it doesnt return a value, is the return statement just used to get out of the if loop?, or maybe something else! help is appreciated!
class TickTock {
synchronized void tick(boolean running) {
if(!running) { // stop the clock
notify(); // notify any waiting threads
return;
System.out.print("Tick ");
notify(); // let tock() run
try {
wait(); // wait for tock() to complete
catch(InterruptedException exc) {
System.out.println("Thread interrupted.");
synchronized void tock(boolean running) {
if(!running) { // stop the clock
notify(); // notify any waiting threads
return;
System.out.println("Tock");
notify(); // let tick() run
try {
wait(); // wait for tick to complete
catch(InterruptedException exc) {
System.out.println("Thread interrupted.");

A simple return statement means that you are just exiting that function. A function can use the return statement even if it is declared a void. It is just that from a void function you can not return a value.
In your code the function is doing some condition checking (if statements) and based on that decides whether to exit the function or to continue going forward.
Additionally, the if-construct is not a loop. If statements provide conditional branching mechanism.
http://java.sun.com/docs/books/tutorial/java/nutsandbolts/branch.html
You probably will never need to break out of an if statement. If you do need it, then perhaps your if condition is suspect.
http://java.sun.com/developer/TechTips/2000/tt0613.html
You can use labeled breaks if you need to break out of nested if statements but it is very rare that you will need them and the code can perhaps be written in another way which is much more readable than labeled breaks.

Migrating legacy code to 2008 R2 standards...

Hi , I'm trying to rewrite the below code which uses tmp tables developed in 2000 version of SQL to 2008 R2 .any help in tuning query is appreciated.. -- Load all ip_id and skill combinations from tblSwDM_stg_SYNONYM into #temp_Complete_Skill_List
INSERT #temp_Complete_Skill_List
SELECT DISTINCT sm.switch_id, s.value, max(s.item_name), max(s.descr)
FROM tblSwDM_stg_SYNONYM s (NOLOCK)
INNER JOIN tblSwDM_SwitchMaster sm (NOLOCK)
ON s.cms_id = sm.cms_id
AND s.acd_no = sm.acd_number
WHERE s.item_type = 'split'
GROUP BY sm.switch_id, s.value
-- Append all additional ip_id and skill combinations from tblSwDM_stg_DSPLIT_UNIQUE into #temp_Complete_Skill_List
INSERT #temp_Complete_Skill_List
SELECT DISTINCT stg.ip_id, stg.split, NULL, NULL

LEFT OUTER JOIN #temp_Complete_Skill_List tmp
ON stg.ip_id = tmp.switch_id
AND stg.split = tmp.skill
WHERE tmp.switch_id IS NULL
AND tmp.skill IS NULL
---- The above code will be later used to load the table below..

>> I'm trying to rewrite the below code which uses TMP tables developed in 2000 version of SQL to 2008 R2<<
How much can you do to upgrade the schema? You have a ton of ISO-111798 violations in the data element names. For example, the prefix “tbl-' is absurdly redundant and it is called “tbling” as a design flaw.
We do not use temp tables in good SQL. This is how an old COBOL programmer fakes using a scratch tape instead of using a derived table, VIEW or CTE. You even do a step-by-step tape merge in SQL!
DISTINCT and GROUP BY are seldom used together. But we have no DDL or other specs, so we do not know. The correct form is INSERT INTO; INSERT is dialect.
The use of NULLIF(skill_name, '') and NULL constant columns is usually a sign of bad design. How can the skill name be an empty string in a valid schema? Where is the explicit “unknown” value? Why create NULLs and then overwrite them in another process step?
(answer: This is how we did data processing with punch cards in the 1960's!)
The term “master” is not RDBMS; it is from tape files and network databases.
Why do you have multiple names for the same data element? What is the generic, vague “value”? Generic vague “skill” (skill_name, skill_level, skill_code, etc), “split”? Likewise, there is no such thing as a “type_id” in RDBMS. Do you have a “blood_type” or
a “blood_type_id”? See the redundancy? People actually will say “blood_type_id_value” or worse.
Did you know that the 1970's Sybase UPDATE..FROM.. does not work or port? Today we might use a MERGE statement.
But my preference would be a
CREATE VIEW Complete_Skill_List (switch_id, something_value, item_name, something_description)
so that it is always correct and current. It will also probably be faster than constantly doing disk seeks and updates.
Any help?

Fuskie-
The way I understand it:
    When the data source is a stored procedure, CR will execute it so if the stored procedure has any
    parameters, it will prompt for them. These parameters are in the stored procedure side. Then, if you
    have additional parameters in the Crystal Report itself, you are going to be asked to input those too.
    This will cause "double prompting".

Interested to learn about your backup workflows?

i'd be curious to know how users back up their data.
i know there are plenty of soft/hardware specs involved, but what i'd be interested to know is how people handle the logistics and workflows in a world of exploding data volumes. the internal hdd will fill up quickly, bootable backups should be separate, yet another external hdd may be used for streaming, itunes content may need to be accessible from various engines through a hdd attached to aebs, aperture has its vault and raw its appetite for capacity, etc.
...and maybe i am paranoid, ten years ago, a burglar may probably not have taken albums with him but today, he will for sure take everything with an apple logo on it...
how do you do it?

I use different backup methods depending on the system and how badly I do NOT want to loose my data.
My MacBook is the most backed up.
a) SuperDuper to a network mounted volume every day at work (this is the only manually started backup).
b) Time Machine when I'm at home.
c) Mozy.com for selected files so I have off-site backup.
d) And rsnapshot for selected files to my workstation at work over lunch.
My Mac mini, uses Time Machine. It is also my home network server with 2TB of external Drobo storage, and it is where my networked MacBook Time Machine backups go.
My Wife's iBook G4 is backed up via rsnapshot every night to my Mac mini external Drobo storage.
My Mom's iMac G4 is backed up over an ssh internet connection every night using rsnapshot to my Mac mini external Drobo storage.
My Wife's MacBook Pro is backed up via Time Machine to the Mac mini external Drobo storage.
My work Redhat Linux development system (2000 miles away) has selected files backed up to my work PowerMac G5 via rsnapshot several times a day over an ssh connection.
My work PowerMac G5 boot disk is backed up via SuperDuper ever night to the other internal disk.
Selected files on my PowerMac G5 are backed up via rsnapshot every night to an external disk.
Select files on several key work systems are backup nightly via tar, which is compressed, and copied over the network to my workstation.
My workstation has about 1.8TB of storage on it. I'm thinking of replacing the 300GB and 500GB internal disks with two 1TB disks now that I'm seeing prices in the $135 range. Another $10 price drop and I think I just might do it

How can Java trap closing DOS window

Hi all:
This pertains to Windows.
I have an application which needs to be shut down in a controlled fashion. Unfortunately I can't get my users to cooperate.
I have learned how to trap for Ctrl-C and do a controlled shut down.
I can't prevent them from closing the window the program runs in or the other ways to shut a program down from Windows.
Is there any way to trap for the user closing the appliation (either by clicking the X in the top right or by choosing Close-AltF4 from the pull down). I would like to trap for the event and do a controlled shut down of the application before Windows pulls the gound out from under it.
Thank!

Hot Deployment & ClassLoader Re-Use

I've implemented a service that observes changes to a jar file's timestamp, and utilizes a new UrlClassLoader to hot deploy class changes. It's working well in isolation, but I wonder how it will perform in production. The work is based on the October 31, 2000 JDC Tech Tips ( http://java.sun.com/developer/TechTips/2000/tt1027.html ).
I've tried to improve on the example code and I wonder if my change will help or haunt me. The example creates a new URLClassLoader every time the class is requested by name. In comparison, I wanted to only create a new class loader when necessary. To do so, I collect the class loader used for a given class name and re-use it on the next request if the underlying jar file has not changed. Is this a wise approach? Anything else I should be thinking about?
Here's some sample code to illustrate:
    protected HashMap jarMap = null;
    protected HashSet classesUpgraded = null;
    protected HashMap classLoaders = null;
    protected IUpgradeObserver observer = null;
    public Class getClass(String xtlClassName) throws ClassNotFoundException {
        Class c = null;
        File f = getJar(xtlClassName);
        observer.notifyIfChanged(f);
        try {
            if(f != null) {
                lazyInitClassesUpgraded();
                if(classesUpgraded.contains(xtlClassName)) {
                    // the jar has changed, so create a new class loader
                    Dbug.print(dbugTag, "Reloading " + xtlClassName + " from jar with timestamp " + f.lastModified());
                    ClassLoader loader = new URLClassLoader(new URL[]{f.toURL()});
                    c = loader.loadClass(xtlClassName);
                    if (c != null) {
                        classesUpgraded.remove(xtlClassName);
                        lazyInitClassLoaders();
                        classLoaders.put(xtlClassName, loader);
                } else {
                    // the class has already been loaded from the current jar - reuse the existing class loader
                    lazyInitClassLoaders();
                    ClassLoader loader = (ClassLoader)classLoaders.get(xtlClassName);
                    c = loader.loadClass(xtlClassName);
        } catch (MalformedURLException urle) {
            urle.printStackTrace();
        if(c == null) {
            throw new ClassNotFoundException("The Xtencil jars did not contain " + xtlClassName);
        } else {
            return c;
    }

legosa - Sure, some portion of getClass must be synchronized to reduce the likelihood of an additional new class def being created when two threads enter getClass at the same time. The other points you make are good as well, and I initially became aware of them in reading the Sun example. As far as I can tell, they shouldn't affect us. I'm not writing a general-purpose class loader. My work is only used to load a specific type of "map" that is frequently updated. We always go through the same factory function to create these maps by name. No singletons will be generated through the utility, and it should be fine for two class objects to exist for a given class name. Basically, the software looks up a map implementation by name, runs it, marks the map as garbage, and moves on to the next. If I plug my class loader into our other web-based container, I have more concerns, since many users may be requesting maps and the old class definitions are less likely to be garbage at any given time.
pekoe - Thanks for the heads up on HotSwap. Unfortunately, as I understand it, the work is intended for development environments, not production servers. For example, it requires the JVM be in debug mode!

Developer on 2000?
