How to deal with NULL when using OCI

I tried to select some data from a table, and some of them are
null.
Can anybody tell me how to deal with the null value?
Thanks!

See the documentation on 'indicator variables'. This is the
correct way of dealing with reading and/or writing NULL data
for a table.

How to deal with images when detecting/resizing screen?

Hi there,
I am trying to learn how to detect screen resolution and
resize a flash movie to those dimensions. The one thing I'm
wondering first is, how to deal with images in the movie.
Do I need a variety of different movie sizes that I serve up
depending on the resolution, or is there some way of linking to
higher rez image that can be scaled down to fit the screen?
Thanks!

as far as I know this has always been a bit of an issue when
using
images inside a scaled movie. If you display a high res image
inside a
scaled down movie, flash can't "reoptimize" it so the image
looks
jagged. Of course the other way around is even worse..
Serving images based on the screen res could be possible if
you detect
it using javascript but could be a night mare to maintain and
test it...
I guess the questions I would ask myselkf are:
1. what is my audience? What resolution the majority of them
will have?
2. Is there anyway I can keep the image size fixed, and scale
to fit he
rest of the design?
3. How much time do I have to implement the customized
version?
It really depends on your project..but to answer to your
quuestion yes
you can detect.
http://www.pageresource.com/jscript/jscreen.htm
and your flash will have to interpret and load images from
different
directories based on the var passed

How to deal with security when migrating application from weblogic 5.1 to weblogic 6.1?

Dear All,
I have one statement int weblogic 5.1 weblogic.propertis as follow,
weblogic.security.realmClass=com.tbcn.security.realm.TestRealm
but after converting to weblogic 6.1 there are no corresponding statement in
the file config.xml. And when i start the new application, error occured.
what should I do?

# WEBLOGIC HTTP SERVLET PROPERTIES
# CLUSTER USERS: Note that ALL servlets should be set up
# in the per-cluster properties file ONLY.
# WebLogic offers different types of servlets for various uses.
# Classpath servlet registration
# The ClasspathServlet is used to serve classes from
# the system CLASSPATH. It is used by applets to load
# classes they depend upon, and is registered against
# the virtual name 'classes' here by default. This means
# you should set your applet codebase to "/classes".
# You can register multiple virtual names for this servlet.
# Note that it can also be used to serve other
# resources/files from the system CLASSPATH.
# Don't confuse the ClasspathServlet with the ServletServlet. The
# ClasspathServlet is used for serving classes for client-side Java only.
# The ServletServlet is used to invoke unregistered servlets.
# See the Administrators Guide "Setting up WebLogic as an HTTP server"

How to deal with Null Variables

AND (CONVERT(varchar, CAST(rtrim(SH.ship_dt) AS datetime), 101) = (CONVERT(varchar, (DATEADD(day, -1, GETDATE())), 101)))
This part of my where clause results in a NULL causing my job to fail since it is setting an integer variable. Any tips? I've tried using ISNULL and can't seem to place it correctly.
Erika

Yes, the null column is ship_dt. When i used that it gave me an error message 245
Msg 245 Conversion failed when converting the varchar value '1900-01-01' to data type int.

Stop/start of BW 7.0 system-- how to deal with deltas when moving instance?

Dear BW guru's,
we are moving a BW 7.0 system to a new datacenter, where the R3 source systems remain the same.
What should we consider when we want to stop the system, move it, and restart the next day, when the source systems cannot be stopped?
Specifically I may need to clear the delta queues in BW before stopping and moving the system.
After the system has been installed in it's new location, can we just the delta process chains without any other action, and will it extract the delta's from source system where it left of before?
is there something I am overlooking?
thanks for tapping your collective brainpower,
-jh

Hi,
When you are miving instance and source would be on during that period then you may look for follwoing.
Stop the loads and resume the delta after movement.
If there are some jobs for fetching data in R3/ for BW data source then those needs to be stopped and rescheduled as some time those jobs define the delta in BW.
If there are pseudo delta or some hardcoding for extracting delte then need to take care of the as well.
I hope it will help.
Thanks,
S

How to deal with "Error 1001. The specified service already exists" when install a service using installer package?

Hi everybody,
I wrote a "Class Library" project which is a service using Visual Stodio 2008 recently, then tried to use a Visual Studio 2008
Setup Project to install it.
Here is what I did for the "Class Library":
1. Finish the program.cs, Service.cs
2. Add Installer
3. Change the serviceInstaller so that "StartType" to be Aotumatic
4. Change the ServiceProcessInstaller2 so that "Account" to be LocalSystem
5.
6. Click in F5 (Start Debugging)
Here is what I did for the Setup Project:
1. Add the exe file built from the "Class Library" project to the Application Folder
2. On the Custom Action Editor, add the exe file from 1 to Install and Commit
3. Change the property of the project so that "RemovePreviousVersion" to be true
4. Click on F6(Build Solution)
Then I tried to run the msi file from the built of the Setup Project. Because I modified the two projects serveral times, I uninstalled the Class Library using "Control Panel->Add or Remove Programs" before I reinstall. Two things I notived:
1. After unstall, the registry was not cleaned up about the installed program
2. After several rounds install/uninstall, I got "Error 1001. The specified service already exists"
My questions are:
1. How to cleanup the registry when uninstall a program?
2. How to deal with the "Error 1001. The specified service already exists"?
3. Did I do anytbing wrong with the "Class Library" or the "Setup Project"?
Thanks a lot!
Helen

Hi Simon, not a problem!
I spent some more time on this and here are few more notes:
it is called Major Upgrade, when you are installing new version of the product upon a previous one and
MSI supports 2 strategies:
Strategy 1. Install a new version and uninstall previous one. (Install a new version right upon previously installed version (file merging is performed based on dll version number) and the delete previously
installed files)
Strategy 2. Uninstall previous version and install a new one (Delete all previous files and install from scratch new files.)
From the first look it seems that 1st strategy is weird and buggy. But, remember, MSI is great because it's transactional!!! That means that if once some of the phases (Installation, Uninstallation, Rollback, Comit) fails, your machine
will be reverted to the previous state and it'll be still functional.
Let's consider both strategies:
Consider you have installed product_v1.msi and you want to install product_v2.msi.
Strategy 1
1. MSI engine copies files from Product_v1 directory to TEMP directory
2. MSI engine merges files based on the assembly version (between v1 and v2)
3. Once merging is completed successfully it removes files in TEMP (RemoveExistingProducts action triggers it) and you got product_v2 installed, otherwise if it fails MSI engine revert machine to V1 and copies previous files from TEMP.
Strategy 2
1. MSI engine tottaly removes all files from v1.
2. MSI engine installs v2 files and if something goes wrong you cannot revert back, because RemoveExistingProducts allready worked out and MSI doesn't have files to revert machine back
I recommend to everybody to use Strategy 1 and leverage MSI transaction functionality. And you can set this strategies by defining sequence of RemoveExistingProducts action. See more info
here. So, I think it's not even a bug in VS as I said in the upper post it is default recommened behaviour.
AND, you got "Error 1001. The specified service already exists"
because if we follow Strategy 1 MSI engine tries to install Windows Service on top of the existing service and OF COURSE it fails MSI engine (StopServices, DeleteServices actions are executed before actual
installation and they look at ServiceControl table). In order to stop service first and delete them you have to fill ServiceContol table of the MSI (and then StopServices, DeleteServices actions will recognize what to they have to stop
and delete), like this:
*clip*clip*clip*
' see http://msdn.microsoft.com/en-us/library/windows/desktop/aa371634(v=vs.85).aspx for more info
' Update the Service Entry to stop and delete service while uninstalling
query = "INSERT INTO ServiceControl (ServiceControl, Name, Event, Arguments, Wait, Component_) VALUES ('MAD_Service', 'Service name', '160', '', '1', '"
+ componentName + "')"
Set view = database.OpenView(query)
: CheckError
view.Execute : CheckError
' Update the Service Entry to stop and delete service while installing
query = "INSERT INTO ServiceControl (ServiceControl, Name, Event, Arguments, Wait, Component_) VALUES ('MAD2_Service', 'Service name', '10', '', '1', '"
+ componentName + "')"
Set view = database.OpenView(query)
: CheckError
view.Execute : CheckError
*clip*clip*clip*
We can uninstall service first by following Strategy 2, but then we lose transactional support.
So, Simon did I encourage you to change your code a bit?:)
And, btw, if you don't want to change the strategy, please don't rely on SequenceID in MSI table, it can be change, you have to get the at the runtime.
Hope it will help to everybody!

How to deal with the rule that do not use "object" class to declear a class

I run my flex project in sonar. And there is a rule "Do not use Object class ".
I just want to know how to deal with this problem.
I mean, when I try to write a base class, I don't know which kind of class will be transfered in by reference, which type I can declear instead of "object"?

Check out this example:
The moment I put in the code >> box1.addItem("hello"); << and run the application, the BusNameListener is fired. Hope this makes sense.
import java.awt.*;
import javax.swing.*;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
public class JFrameExample {
private JComboBox box1;
public JFrameExample() {
box1 = new JComboBox();
box1 .setMinimumSize(new Dimension(300, 24));
box1 .setPreferredSize(new Dimension(300, 24));
box1.addActionListener(new BusNameListener());
box1.addItem("hello");
JFrame f = new JFrame("This is a test");
f.setSize(400, 150);
Container content = f.getContentPane();
// content.setBackground(Color.white);
content.setLayout(new FlowLayout());
content.add(box1);
f.setVisible(true);
class BusNameListener implements ActionListener {
public void actionPerformed(ActionEvent e) {
JComboBox cb = (JComboBox) e.getSource();
String item = (String) cb.getSelectedItem();
if (item != null) {
JOptionPane.showInputDialog(null,
"Specify...", "File Import",
JOptionPane.OK_CANCEL_OPTION);
}

Hi Paulbin,
Do you want to supply a function-pointer to a DLL so it can call[back] your VI? Here's how it can be done with .NET, though, that solution requires a C compiler. A single "VI_to_function-reference" utility could handle all cases where the callback passes no parameters. Maybe someday somebody will share that dll.
Did you know that LabVIEW can use Events for some COM-signals change? See pic. (Note: DTR is not listed - - )
Another question is another function's prototype is WORD SetTestType(WORD comHandle, bool type1, bool type2, bool type3), I tried to use a boolean control and a Boolean to (0,1) node in labVIEW to pass parameters to CLF, I config the bool input value as U8(according to C++ bool type) and U32(according to WIN32 BOOL type), it dose not help, when I execute the VI, LabVIEW will be disappeare, it seems to be closed, I must start it again.
Could someone has similar experience on this points?
It's easy to crash LabVIEW misusing CLF - maybe there's another reason for the crash besides bool mis-match(?) Do you know which "Calling convention" is required? What type is comHandle? (where does comHandle come from?)
Cheers!

How to deal with deadlock on wwv_flow_data table when http server times out

There are some threads about a deadlock on the wwv_flow_data table. None of them contain a real explanation for this behaviour. In my case I will try to explain what I think is happening. Maybe it helps somebody who is hitting the same matter.
In my case with APEX 3.2.1 I am navigating from one page to another. Doing this APEX will lock the table wwv_flow_data. As soon as the other page is shown the lock will be released. But now this other page contains a bad performing query (standaard report region). After 5 minutes the http server (modplsql) will time out and present the message "No response from the application server" on the screen. In the meanwhile the query is still running on the database server and the lock stays on the wwv_flow_data table.
Normal user behaviour will be that the user will use the back button to return to the previous page and tries it again to navigate to the other page or
the user will try to refresh the page with the bad performing query.
And voila now you will have a deadlock on the wwv_flow_data table since a second session is trying to do the same thing while the first hasn't finished yet.
How to deal with it?
First of all. Have a good look at the bad performing query. Maybe you can improve it that it will succeed before the http server will timeout.
In my case the 11gr1 optimizer couldn't handle a subquery factoring clause in the best way. After changing it back to a classical inline query the problem was solved.
Secondly you could increase the timeout parameter of the http server. Although this not the best way.
Maybe it would better if APEX in a next version would release the lock on the table wwv_flow_date earlier or do a rollback just before the moment that the http server is timing out.
regards,
Mathieu Meeuwissen

Hello Shmoove,
I saw your reply here and you probably understand the problems the HTTP 100 response may cause.
I am trying to send image that was taken by getSnapshot. The problem is that the server respond with this HTTP 100 message.
I suspect that the reason that my server doesn't recognize the file that I'm sending from J2me is that the "server to client" response to the 100 message comes after the second message of (see what the TCPIP viewer shows down here):

How to deal with credentials for external applications using a Java Client/

Hi Guys,
This is the case. I am integrating an external application with an ADF Application. I have implemented some programmatic ViewObjects that are being filled up by a REST Java Client Wrapper. Everything is working fine but the issue is that the credentials the wrapper is using are hard coded inside the java class. I am thinking to ask for the credentials at the beginning of my taskflow and then store them somewhere and use them then to create my client wrapper (passing them in the constructor).
However, I don't know if my approach is good and I would like you to share your experiences or how to deal with this.
Regards

You can use Credential Store Framework to store the credentials securely in the weblogic server instead of hardcoding in the java class.
The Credential Store Framework:
- enables you to manage credentials securely
- provides an API for storage, retrieval, and maintenance of credentials in different back-end repositories
Check the documentation on CSF API -
http://docs.oracle.com/cd/E29505_01/core.1111/e10043/devcsf.htm
Major Steps -
1. Create a credential map and key in em console to store the password (http://docs.oracle.com/cd/E25054_01/core.1111/e10043/csfadmin.htm)
2. Use CSF API to retrieve the stored password
3. In jazn-data.xml give permissions to access CSF key and map

SQL Developer 3.2 crashes with java error when using OCI/Thick Driver

I just installed SQL Developer 3.2 on my linux desktop. SQL Developer crashes with a java error when I select a database from the object tree.
When I check Use OCI/Thick driver the application will crash when I navigate to the tree and open a database.
The app does not crash then I have Use OCI/Thick driver unchecked.
Here are some details of my environment:

I also had the problem of SQL Developer crashing when using OCI/Thick driver but I've managed to solve it. My configuration is:
- Windows 64-bit
- Java 64-bit (1.6.0.34)
- SQL Developer 3.2.09 64-bit
- OCI Instant client 11.2.0.3 64-bit (without installation).
The thing that solved the problem was copying two files, ojdbc5.jar and ojdbc6.jar, from Instant client installation folder to JAVA_HOME/lib/ext folder+.
After that, I haven't had a single crash or error message.
The same trick that solved the problem on 64-bit installation also solved the problem on another windows computer with 32-bit SQL Developer installation.

How to deal with user session when power goes off

Hi
All,
One day I had 170 oracle session connected on oracle database server and and suddenly electricity went off. but server was still running. and after power back on ther same bunch of user try to connect it.So I don't know what happen to those 170 session. does anybody know how to deal with this? I did shutdown and restart of database but I am not sure that is correct way to deal with this kind of situation.
Thanks,
Vishal

If the database server is still running, the sessions will remain there, but it depends on how they got connected to the server. If they got access through a middle tier which maintains the session and this MT is still running the sessions will still be visible from the database perspective, unless the MT handles the disconnection event.
If the sessions are working on a Client-Server basis, then PMON will mark the sessions as abruptly broken and it will get rid of them. Sessions may eventually remain hanged, but it depends on the topology, so the way you proceed was a clean database restart.
