How are the java system properties loaded into the Oracle 8.1.7

I have listed the java system properties both standalone and in the Oracle database. The standard list of system properties is quite extensive and informative. But the list of system properties from the Oracle database is severely truncated.
I expect these properties are initialized on database startup.
If that is the case, I expect there to be a file and initialization parameters that define where the information is kept and there values.
Can anyone give me some guidance?

System*.properties file should be located in the $ORACLE_HOME/javavm/jahome directory

How the "Java System Properties" are populated in "About this Page"

Hi Gurus,
We are facing a very intriguing issue and want to find out the way self service pages shows information in tab "Java System Properties" on clicking "About This Page" link ( bottom left corner of any EBSO selef service page)
Thanks,
Ajay

Hi Peddi,
Thanks but let me give some more details on our problem.
It is a EBSO environment.
On Private MT we do not have any proxies set in context file or any other configuration files.
<proxyhost oa_var="s_proxyhost"> </proxyhost>
<proxyport oa_var="s_proxyport"> </proxyport>
The standard all standard OAF pages ( no customization or personalization ) show via link I mentioned before show these variables set
http.proxyHost
http.proxyPort
http.proxySet
Any idea how these get populated ?
Are these values fetched dynamically via some DB table?
Thanks,
Ajay

Incremental load into the Dimension table

Hi,
I have the problem in doing the incremental load of the dimension table.Before loading into the dimension table,i would like to check the data in the dimnesion table.
In my dimension table i have one not null surrogate key and the other null dimension tables.The not null surrogate key, i am populating with the Sequence Generator.
To do the incremental load i have done the following.
I made lookup into the dimension table and looked for a key.The key from the lookup table i have passed to the expression operator.In the expression operator i have created one field and hard coded one flag based on the key from the lookup table.I passed this flag to the filter operator and rest of the fields from the source.
By doing this i am not able to pass the new records to the dimension table.
Can you please help me.
I have another question also.
How do i update one not null key in the fact table.
Thanks
Vinay

Hi Mark,
Thanks for your help to solve my problem.I thought i share more information by giving the sql.
I am giving below the 2 sqls, i would like to achieve through OWB.
Both the following tasks need to be accomplished after loading the fact table.
task1:
UPDATE fact_table c
SET c.dimension_table_key =
(SELECT nvl(dimension_table.dimension_table_key,0)
FROM src_dimension_table t,
dimension_table dimension_table
WHERE c.ssn = t.ssn(+)
AND c.date_src_key = to_number(t.date_src(+), '99999999')
AND c.time_src_key = to_number(substr(t.time_src(+), 1, 4), '99999999')
AND c.wk_src = to_number(concat(t.wk_src_year(+), concat(t.wk_src_month(+), t.wk_src_day(+))), '99999999')
AND nvl(t.field1, 'Y') = nvl(dimension_table.field1, 'Y')
AND nvl(t.field2, 'Y') = nvl(dimension_table.field2, 'Y')
AND nvl(t.field3, 'Y') = nvl(dimension_table.field3, 'Y')
AND nvl(t.field4, 'Y') = nvl(dimension_table.field4, 'Y')
AND nvl(t.field5, 'Y') = nvl(dimension_table.field5, 'Y')
AND nvl(t.field6, 'Y') = nvl(dimension_table.field6, 'Y')
AND nvl(t.field7, 'Y') = nvl(dimension_table.field7, 'Y')
AND nvl(t.field8, 'Y') = nvl(dimension_table.field8, 'Y')
AND nvl(t.field9, 'Y') = nvl(dimension_table.field9, 'Y')
WHERE c.dimension_table_key = 0;
fact table in the above sql is fact_table
dimesion table in the above sql is dimension_table
source table for the dimension table is src_dimension_table
dimension_table_key is a not null key in the fact table
task2:
update fact_table cf
set cf.key_1 =
(select nvl(max(p.key_1),0) from dimension_table p
where p.field1 = cf.field1
and p.source='YY')
where cf.key_1 = 0;
fact table in the above sql is fact_table
dimesion table in the above sql is dimension_table
key_1 is a not null key in the fact table
Is it possible to achieve the above tasks through Oracle Warehouse builder(OWB).I created the mappings for loading the dimension table and fact table and they are working fine.But the above two queries i am not able to achieve through OWB.I would be thankful if you can help me out.
Thanks

Java system properties

In weblogic 10.3, is it possible to set java arguments by using the console only?
I tried to put:
-DmyArg=XXX
inside the Arguments section of my weblogic server under the tab "Server start".
However, when I start the server and look at the logs, the Java system properties are printed there, but I can't see my new property..
Thanks.

Well, if you use script to start server, then you need to add required settings to the script.
Arguments field in startup properties are processed by the NodeManager while executing command to start server. See here for more details: http://e-docs.bea.com/wls/docs92/server_start/nodemgr.html#wp1081792

Downloadhelper just stopped working and I can no longer get the icon to load into the tool bar.

I downloaded the add on Downloadhelper and it worked for many video captures and then stopped. I reinstalled it but the icon will not load into the toolbar or the tools under View -> Toolbars -> Customize. I have gone through the troubleshooting guides and everything seems to be enabled properly. At the same time Firefox stopped allowing me to open more than one Firefox screen.

Contact the carrier and ask them what is going on.

How to list the JAR files loaded into the Oracle Database ?

How to list the JAR files loaded into the Oracle Database ?

From 11.1 onwards, the below two views are available to identify the jar files loaded into the Database.
JAVAJAR$
JAVAJAROBJECTS$
By querying the JAVAJAR$ view you can know information about the JAR files loaded into the Database and using JAVAJAROBJECTS$ view you can find all the java objects associated with the given JAR file.
These views are populated everytime you use LOADJAVA with "-jarsasdbobjects" option to load your custom java classes.
But unfortunately this feature is available only from 11.1 onwards and there is no clear workaround for above in 10.2 or earlier.

How to load a class dynamically in the current/system class loader

I need to dynamically load a new jdbc driver jar to the current/system class loader... Please note that creating a new classloader will not help since the DriverManager refers to the systemclassloader itself.
Restarting the application by appending the jar to its classpath will solve the problem but I want to avoid doing this.

Did you then create a ClassLoader to load the JDBC
driver and then install it into the system as
directed by the JDBC specification (ie
Class.forName(someClassName))?
And then try to use it from a class loaded fromsome
other ClassLoader (i.e. the system class loader)?
If you did not try this please explain why not.O.K. I just looked at the source to
java.sql.DriverManager. I did not know what I was
talking about, as what I suggested above will not
work.
This is my new Idea:
Create a URLClassLoader to load the JDBC driver also
in this ClassLoader you need to place a helper class
that does the following:
public class Helper {
public Driver getJDBCDriver(String driverClassName,
String url) {
try {
Class.forName(driverClassName);
Driver d = DriverManager.getDriver(url);
return d;
catch(Exception ex) {
ex.printStackTrace();
return null;
}Now create an instance of the Helper class in the new
ClassLoader, and call its getJDBCDriver method to get
an instance of the driver (you will probably have to
create an interface in the root class loader that the
Helper implements so that you can easily call it).
Now from the root classloader you can make calls
directly to the returned Driver and bypass the
DriverManager and its restrictions on cross
ClassLoader access.
The only catch here is that you would have to call to
the returned Driver directly and not use the Driver
Manager.This sounds like will work but I did not want to load DriverManager in a new classloader.. I did a hack
I unzip the jar dynamically in a previously known location (which I included in my classpath when launching the app). The classLoader finds the class now though it did not exist when the app was launched !
A hack of-course but works eh ..

How can i add the dimensions and data loading into planning apllications?

Now please let me know how can i add the dimensions and data loading into planning apllication without manuallly?

you can use tools like ODI or DIM or HAL to load metadata & data into planning applications.
The data load can be done at the Essbase end using rules file. But metadata changes should flow from planning to essbase through any of above mentioned tools and also there are many other way to achieve the same.

How to read the data file and write into the same file without a temp table

Hi,
I have a requirement as below:
We are running lockbox process for several business, but for a few businesses we have requirement where in we receive a flat file in different format other than how the transmission format is defined.
This is a 10.7 to 11.10 migration. In 10.7 the users are using a custom table into which they are first loading the raw data and writing a pl/sql validation on that and loading it into a new flat file and then running the lockbox process.
But in 11.10 we want to restrict using temp table how can we achieve this.
Can we read the file first and then do validations accordingly and then write to the same file and process the lockbox.
Any inputs are highly appreciated.
Thanks & Regards,
Lakshmi Kalyan Vara Prasad.

Hello Gurus,
Let me tell you about my requirement clearly with an example.
Problem:
i am receiving a dat file from bank in below format
105A371273020563007 07030415509174REF3178503 001367423860020015E129045
in this detail 1 record starting from 38th character to next 15 characters is merchant reference number
REF3178503 --- REF denotes it as Sales Order
ACC denotes it as Customer No
INV denotes it as Transaction Number
based on this 15 characters......my validation comes.
If i see REF i need to pick that complete record and then fill that record with the SO details as per my system and then submit the file for lockbox processing.
In 10.7 they created a temporary table into which they are loading the data using a control file....once the data is loaded into the temporary table then they are doing a validation and updating the record exactly as required and then creating one another file and then submitting the file for lockbox processing.
Where as in 11.10 they want to bypass these temporary tables and writing it into a different file.
Can this be handled by writing a pl/sql procedure ??
My findings:
May be i am wrong.......but i think .......if we first get the data into ar_payments_interface_all table and then do the validations and then complete the lockbox process may help.
Any suggestions from Oracle GURUS is highly appreciated.
Thanks & Regards,
Lakshmi Kalyan Vara Prasad.

Sun Java System Application Server into Netbean 6.1

Hi , I am new to Java community,
I like to lean J2EE so I downloaded
jdk-1_5_0_16-windows-i586-p and installed
then I installed
java-tools-bundle-update5-windows
I am trying to do the initial setup and do the sample
The Java EE 5 Tutorial
See this tutorial for information on building and deploying Java EE 5 applications.
When I try to register the Sun Java System Application Server into Netbean 6.1
I could not I have warning, says
Provide a valid server installation location
But I gave, C:\Sun\AppServer
If you guys can give any light on this appreciated

It doesn't sound like you have installed a Java EE (formerly J2EE) application server. Your download of "jdk-1_5_0_16-windows-i586-p" is Java Standard Edition, which you need, but you also need an implementation of Java Enterprise Edition. The [Sun Java System Application Server|http://developers.sun.com/appserver/] is certainly a valid Java EE implementation, but I don't see in your steps where you downloaded that. There are several types of NetBeans downloads ("bundles") you can perform and I believe that one or more bundles (such as "All" and "Web & Java EE") includes GlassFish as part of the download. I recommend using the GlassFish Java EE implementation that comes with NetBeans 6.1 for learning how to use Java EE with NetBeans. Alternatively, you can download GlassFish separately at [https://glassfish.dev.java.net/|https://glassfish.dev.java.net/].

How do I set System properties within WL6.0?

I am setting WL6.0 up to have a startup class, but this class needs to
read system properties which have not yet been set. How do I set these
up within weblogic? I was able to get the startup class set up, but it
needs these system properties to continue.
gmo

Correct on all points. The one advantage of doing this in java is that you can more easily do more
complex things like accessing configuration information from a remote data store (like a database).
Dimitri Rakitine wrote:
These are not needed if you simply replace java ...lots of options... weblogic.Server with
java ...lots of options... startmyWLS in the script which starts WebLogic, but, on the other
hand, this solution is no different from simply adding -DmyProperty=myValue to the startup script
(I think that the ultimate goal is the ability to deploy(and redeploy!) components,
without any mods to the particular vendor's startup scripts of anything of that nature).

Thanks to robert for a quick workaround..
I tried to start the WLS with the following piece of code and actually i need to set

Here it is
import java.util.Properties;

public static void main(String[] args)
Properties props = System.getProperties();
props.put("myProperty", "myValue");
props.put("bea.home", "E:\\bea");

props.put("java.security.policy",
"E:\\bea\\wlserver6.0\\lib\\weblogic.policy");
System.setProperties(props);
weblogic.Server.main(args);
Make sure you run this from E:\bea\wlserver6.0., as it tries to read config.xml
config\[your-domain-name] from this
directory.

That won't work since it has to be 'outside' of the code. It's a service, and
services are started when weblogic is started up, not when I call a bean.
And it has to be dynamic, since the properties will vary on evry installation.

set them on the command line when starting up weblogic. However, is this

Can CD's be loaded into the cloud to be accessed by my IPad?

Can CD's be loaded into the Cloud from a PC then be accessed from my IPad?

You need to install Photoshop on your new machine. Once installed you can sync you new installation with your old cc install. If your assets and Photoshop add-ons are on the external drive your done if you link them into you Photoshop paths. I prefer to copy my Photoshop add-on like Plug-ins and Scripts to the boot disk and link then in there. Adobe removed additional plug-in folder from preferences and never had an additional script folder support. Using Files system links work just fine. I have CS2, CS6, CC and CC 2014, They all share the same Plug-ins and Scripts. Some do not work in CS2 because they user new features not in CS2.
