Use java thread? or Oracle DB scheduler?

I have a java thread which purge records in a table every 30 seconds. The thread calls a prepared statement which is like "delete from MyTable where status=99"
can I use DB's scheduled job to do the same thing? I can create a DB schedule, and a job in plsql.
Thus I can save on DB connections.
Which one is better in terms of performance?

i personally recommend against PL/SQL if you can manage it
some will argue that it's okay to couple yourself to a database because you're likely not to change it
but i've seen enough migrations to know the painConversely I have seen attempts to process data by dragging it across the network in the vain attempt to make the application database agnostic. Which results in orders of magnitude more processing time when the application needs to do anything approaching real volume.

Thanks you very much.

It is unclear where you are having a problem. Is your issue at runtime (when the form runs in the browser) or when working in the Builder on the form?
Also be aware that you will need to sign your jar and include some new manifest entries. Refer to the Java 7u51 documentation and blogs that discuss the changes.

How to use Java Script in Oracle Forms 10g

Hello,
Appreciate if anyone could help me using Java Script in Oracle Forms 10g?
Thanks
GM

Thank you for your reply. I was reading on the metalink that we could use the to call the java script from oracle Forms 10g (Doc ID 265863.1)
Example:
WEB.SHOW_DOCUMENT ('javascript:void(window.open("http://www.oracle.com","","location=no,toolbar=no,menubar=no,status=no,"));self.close()','_blank');
I tried it but it did not open the any window as it claims. Am I missing anything? Is there any IE related setting which I need to modify for the above to work?

Help : Unable to use Java Beans in Oracle forms 6i

Hi ,
I have been trying to run few sample code to understand how to use Java beans in oracle forms 6i .But have been largely unsuccessfull.
It will be great if somebody can provide me with some simple form( and java code )which uses java beans concept to give some data to the java program and receive some data from it . Pls inform me about the settings that need to be done.
If you guys know it then pls take the pains of writing a simple form and java code.
i hope somebody will respond because your reply is very necesary for me to proceed.
U can email me the code > [email protected]
Thanks in advance.

Thanks for your reply Francois.
Actually i am not facing problem understanding the programming technique.
I think the problem at my end is more of a cofiguration one.I am using forms version 6i
on oracle 8.
Every time i set the imlementation class property of the bean area it gives an error 13010 which translates to that "the class being mentioned is not extending the IView class".
The class i have written extends VBean so i am not sure why this error is occuring.
I think if oracle (correctly) finds the java class to use then i will be able to proceed.
Pls reply.
If you have some code that is working fine then pls send it to me.And also inform is some environment variables have to be set for its use.

Unable to get 'InitialContext' using Java Client in Oracle App 10.0.2.0

Scenario & Problem Description: Unable to get 'Initial Context' using Simple Java Client in Oracle Application Server 10.0.2.0
I'm having an issue while I try to initialize the Initial Context for an EJB lookup from a simple Java Client [local lookup], but the same code snippet works fine when I try from Servlet. I have enclosed the Exception Stack Trace and the Code Snippet for your reference.

throw ne;
Note:
1. The user "ias_admin" & password "ias123" are the credential provided for the 'Admin' while installing the Oracle App Server and using these credentials I'm able to bring the Admin Console. Also, added new user 'guest/guest' - assigned this user to the 'admin' group ...
2. Since its a local lookup, there is no need to specify the credentials, but at runtime a dialog box pops up prompting to enter the 'userid/password' and when I enter the crendtials, I get the exception as stated. [In case of Servlet - EJB lookup, I'm not specifying any credentials]
Are there are any configuration parameters which I need to provide in any of the .xml? Could you please let me know the fix for the same.

How to use java programe in oracle form

Hello Expert,
My Config is : -
Forms [32 Bit] Version 11.1.1.3.0 (Production)
Jdeveloper - 10.1.3
I want to use the java programe in form builder. I create the one java class in Jdeveloper -
package demo;
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
public class get_info{
   public static void main(String[] args){
   ch_add();
   public static void ch_add()
InetAddress ip;
try {
ip = InetAddress.getLocalHost();
/*System.out.println("Current IP address : " + ip.getHostAddress()); */
NetworkInterface network = NetworkInterface.getByInetAddress(ip);
byte[] mac = network.getHardwareAddress();
/*System.out.print("Current MAC address : ");   */
StringBuilder sb = new StringBuilder();
for (int i = 0; i < mac.length; i++)
sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));
System.out.println(sb.toString());
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (SocketException e){
e.printStackTrace();
and this into Formweb.cfg and default.env and also add into Form_class_path. After that i import this java into forms.

Using Java Dictionary With Oracle

Can Someone tell how can i configure my java dictionary with oracle...Currently if a create a table from my IDE and then deploy it it deploys to the Default SAP DB ...how do i directrly create tables in oracle by just specifying the Deploy option ...
And further on I want my web Dynpro application to talk with oracle db..how do i acheive this..
Please Help!!

Hi,
Does this mean that the additional features of The Java Dictionary (bufferring etc ) can only be implemented if we ONLY connect to the SAP DB---- YES
If I have to utilize the services of Java Dictionary in my application i can only use The SAP DB database -- YES
You deploy a dictionary project to create a table in the DB.
When it is a DB created and used by Web AS ,it is possible to create tables in that DB with dictionary project using the standard connection parameters specified in visual admin.
Java Dictionary purpose is to create a DB abstraction by providing a standard interface to create tables whatever the DB used by WebAS maybe.

How to use Java threads in ColdFusion

Hello Everybody,
I have a question in concerns to threads. We all know that in

Hello Experts,
I am using Oracle forms 11.1.2.2.0 with weblogic 10.3.6 generic at windows 7 64 bit.
My java version is jdk1.7.0_51.
Now I have a htmlbutton.jar (which is for bean item in oracle form and this jar file works well for oracle forms 11g 32 bit windows 7 environment).
I have takken steps:
1:-Put jar file in home\java folder.
2:-add this jar file into archive in formsweb.cfg.
3:-Add this this jar file(which is in my home- java folder) in form_class path in registry.
Now when I try to locate this jar file in my oracle form.There is no such jar file.what are the steps to use this jar file in oracle forms bean item.
Please told me what is wrong here.
thank you

It is unclear where you are having a problem. Is your issue at runtime (when the form runs in the browser) or when working in the Builder on the form?

Cannot use Java Mail in Oracle 8i

I have loaded Sun's API Java Mail (and Java Activator) into
an Oracle 8.1.5 server running on a Windows NT 4.0 server.
I have also created a small Java-application that tries to
send emails. The application is stored in database as a stored
procedure.
However, when I try to send a mail through my stored procedure
I get the message:
'ORA-01041 internal error. hostdef extension doesn't exist'
followed by an end-of-channel error.
It works fine when I run my Java-program stand-alone, without
any database involved.
I need some help with this one...

How to upgrade Forms 11gR2 to use JAVA 7 after it was installed with JAVA 6

I recently installed Forms 11gR2 on a development server. We are trying to have the latest versions of everything to migrate from Forms 10g and assure we have support for the next few years.
Our platform has the following software configuration:
Solaris 10 (Update 19) SPARC 64 bits
Weblogic 11g (10.3.6) that was installed with Java JDK 1.6.0_38
Forms 11g R2 (11.1.2.1) that was also installed with
Java JDK 1.6.0_38
I tried to install Weblogic and Forms using the latest Java 7 JDK (1.7.0_25) but I got an error in the final steps of Forms setup, when I was configuring the domain. I searched online and found a couple of tips but nothing worked. The installation was stuck at the
Creating Weblogic Domain step. So I decided to try the installation process with the Java 6 JDK that we are using right now for Forms 10g, and it worked perfectly. I have now two options but I don't know which one might be the better path:
Uninstall Weblogic and Forms 11g completely, and try to re-install them again with Java 7, trying to fix the error that I got at the end of the configuration process.
Try to upgrade the current Forms 11g installation from Java 6 to Java 7. I found a blog that might suggest it is possible, but I don't know if it may cause additional issues along the road. http://pitss.com/us/2013/02/20/how-to-use-java-7-with-oracle-forms-11g-in-an-oracle-supported-environment/
Thanks in advance for any suggestions you might have, or if any of you has experience installing Forms 11gR2 with Java 7 it might be great to know how to fix this error. It might be worth mentioning that when I installed Forms and Weblogic with Java 6 I used exactly the same values, ports, options and paths. The error appears like this in the installation logs and the process hangs there:

Well if I got it to work with java 6 I'd leave it alone, to say the least. The elephant in the room is the certification matrix.
http://www.oracle.com/technetwork/developer-tools/forms/overview/index.html
there's 2 issues, what jdk does forms on the server want? Bigger question, what JRE is acceptable on the client?
You would surely want the jre to be 7 on the client. Regarding the jdk on the server, you could leave it as is IMHO.
Note that there was a patch to 11gr2. In conclusion, be sure to check the cert matrix regarding what is certified for the jdk for the server.
I think the matrices are saying that if you have forms 11.1.2.1.0 that you can use the jdk 7. but like I said the big issue is what can the client use?
As I read the matrix I think it is saying you have to have 11.1.2.1.0 to use the jre 7 on the client.
So I would say if you have 11.1.2.1.0 on the server you are good because it's not a problem to have the jdk 6 on the server, if not you have to apply the patch in order to enable the jre 7 on the client.

Java threads monitoring

I am using Java threads in my Java program, running on Windows Professional 2000. I am monitoring the threads using Windows Performance Monitor (WPM). However, even running a small Java program which creates only 2 threads, results in many (at least 10) instances of Java threads being reported by the WPM. Problem is, in WPM, there is no way to determine which threads in the WPM are the threads that I programmatically created. Any ideas on how to determine this?
Thanks.

Hi Dmirty ,
To handle large asynchronous message in queues you can use message packaging where multiple message are processed in one package . to make it applicable you have to perform these simple steps
1. go to SXMB_ADM add one RUNTIME parameter PACKAGING and value 1
2 GO TO transaction SXMS_BCONF set delay time 0 message count 100 messages and package size 1000 KB
with these setting your improvement will increase .secondly also put IN SXMB_ADM monitor category parameter QRFC_RESTART_ALLOWED TO 1
this will automatically start your queue . Only thing you have to take care if you enable packaging them don't keep too many parallel queue i.e EO_INBOUND_PARALLEL and EO_OUTBOUND_PARALLEL should be less than 20

Error while importing java class into oracle forms 10g

Hi
I have generated a web service client using jdeveloper 10g. It consists of complex type methods. I am trying to import the class files using java importer in oracle form 10g. I am able import all of them successfully except one. That one is the main method. Please see the error and suggest me how to overcome this error.
Exception occurred: java.lang.NoClassDefFoundError: oracle/jdeveloper/webservices/runtime/WrappedDocLiteralStub
Thanks in advance

Do you see oracle/jdeveloper listed in "Import Java Classes" when you try to import?
If not, make sure you add C:\DevSuiteHome_1\jdev\lib\jdev.jar to FORMS_BUILDER_CLASSPATH in registry
Also excetion indicates: oracle/jdeveloper/webservices/runtime/WrappedDocLiteralStub
If you typing it - type: oracle.jdeveloper.webservices.runtime.WrappedDocLiteralStub

Use java thread? or Oracle DB scheduler?
