How to dynamically refresh system properties when changed

Hi All,
Through weblogic startup class I'm loading the properties from a properties file
into system properties, Now my requirement is to refresh those system properties
when ever I make changes to the properties.
Is there any way to achieve this functionality through MBeans.

Hello Lucky,
I believe you cannot refresh properties file dynamically using MBeans. What
you can do is write an MBean which necessrily mirror your property file and
register with MBeanServer. You can set values on the MBean dynamically but
in order to persist your changes you need to write your own persistance
mechanism.
Cheers

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.

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
some additional properties
for successful server startup.
Here it is
import java.util.Properties;
public class startmyWLS
public static void main(String[] args)
Properties props = System.getProperties();
props.put("myProperty", "myValue");
props.put("bea.home", "E:\\bea");
props.put("weblogic.Domain", "mydomain");
props.put("weblogic.Name", "myserver");
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.

You can also use System.setProperty() or a combination of

They are not normal system properties. I'm using some open source code, and
it requires settings to be system properties, but they are specific to the
application, which means that they are not already in the system
properties. I know how to get them, and after some more research, you can
set them on the command line when starting up weblogic. However, is this
the best way to set system properties?

How to set JVM system properties in Oracle Portal ??

Hello Guys,
I want to set javax.net.ssl.trustStore="path to keystore" ,JVM system properties on oracle portal,
Like i want to configure my keystore with oracle portal so that my application can make a success full connection with back end using https.
i read the following note from one of the Oracle tech note,which says that
It is important that this system property is passed as a command line option to Oracle Application Server Containers for J2EE (OC4J). Setting the property in oc4j.properties will not help because the system property is read first before OC4J reads this file. Therefore, it is best to modify the <java-option> line in the OC4J_portal section of ORACLE_HOME/opmn/conf/opmn.xml.
So, i made the required changes to OC4J_portal section of opmn.xml file as below
added value is shown in bold
<data id="java-options" value="-server -Xrs -Djava.security.policy=C:\oracle\OraPortal\j2ee\OC4J_Portal\config\java2.policy -Djava.awt.headless=true -Xmx256m -Djavax.net.ssl.trustStrore=C:\keystore1 -Djavax.net.ssl.trustStrorePassword=password1"/>
Even after making these changes, my application not able to make connection using https.
Could u guys explain me, what things are going wrong or somethings else i need to do to make it work.
Any thoughts would be highly appreciated.
Thanks

Hello Guys,
I want to set javax.net.ssl.trustStore="path to
keystore" ,JVM system properties on oracle
portal,
-Xmx256m -Djavax.net.ssl.trustStrore=C:\keystore1
-Djavax.net.ssl.trustStrorePassword=password1"/>Hi,
if the above is an exact copy of the values you inserted then it looks like you have two typos in the command line parameters.
-Djavax.net.ssl.trustStrore -> trustStore
-Djavax.net.ssl.trustStrorePassword -> trustStorePassword

How can I get system properties?

Hello,
How can I get the system properties like %JAVA_HOME% in my java codes, for example, I want to print it like this.
System.out.println("%JAVA_HOME%");
but it doesn't work!
Please give me a hand!

To pass the Operating system environment variable to the Java "environment variables", you have to explicitely pass them on the command line eg.
java -Dmyjava.home=%JAVA_HOME% myClass
then, in your code use
String JAVA_HOME = System.getProperty ( "myjava.home" );regards,

How to scope 3 system TMS when only DEV available?

I will build a 3 system TMS with DEV, QAS and PRD.
But now, I have only DEV system available, and QAS and PRD system will available several month later.
And before QAS and PRD system available, the developer will develop in DEV system, so how can I build the TMS system?
with only one DEV system? or set up another 2 virtual system(QAS and PRD)?
I should make sure that the requests which created now, can transfer to the QAS and PRD system in the furture.
Thanks in advance.
Regards,
Randy

Hi Randy,
Your instincts are correct...and this is common...set up QAS and PRD as virtual systems now and change them to actual systems later.
Best Regards,
Matt

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 to find out System properties are available

Hello,
Is there a way to get a list of the properties that are available 'out-of-the-box' on Netweaver via the System.getProperty("xxx") method?
In other words, can I get a list of the possible values for "xxx"?
I know I can add my own properties but I'm more interested in finding out what is available to me by default. What I'm looking for may already be there. Plus, this list would tell me what constant NOT to use if I'm adding my own property.
Thanks in advance for any help.
David.

David, System class has method getProperties which returns instance of Properties (http://java.sun.com/j2se/1.4.2/docs/api/java/util/Properties.html). Iterate through it using propertyNames() and you will get all system properties available.
Best regards, Maksim Rashchynski.

Shared Reminders: How do I stop getting emails when changes are made?

My wife and I both have iPhone 5's that we bought 2 weeks ago. We are sharing a calendar and a "Grocery" list in reminders. I have everything set up where it is working properly but I keep getting emails when a change is made to the grocery list. I don't get emails when there are changes to the calendar.
I want to stop getting emails when there are changes made to our grocery list but I am not sure how to do it. We both have icloud accounts and we both have checked the box under preferences in my calendar for "in app notifications" for icloud invitations. When I open Reminders in icloud I don't see a preferences for reminders.
If it helps , or makes any difference, my wife has a yahoo mail account and I have a hotmail account. She does not get emails about changes being made.
thanks

Did you try to switch Push "off" and fetch to "manually"? This way no mail is delivered until you choose to open the mail app. The moment you open Mail on your device, your mail account will be checked and if any, mail will be delivered.
Fetch New Data
This setting lets you turn Push on or off for MobileMe, Microsoft Exchange, Yahoo!, and any other push accounts on iPhone. Push accounts deliver new information to iPhone whenever new information appears on the server (some delays may occur). You might want to turn Push off to suspend delivery of email and other information, or to conserve battery life.
When Push is off, and with accounts that don’t support push, data can still be fetched—that is, iPhone can check with the server and see if new information is available. Use the Fetch New Data setting to determine how often data is requested. For optimal battery life, don’t fetch too often.
Turn Push on: Choose “Mail, Contacts, Calendars” > Fetch New Data, then tap to turn Push on.
Set the interval to fetch data: Choose “Mail, Contacts, Calendars” > Fetch New Data, then choose how often you want to fetch data for all accounts.
To conserve battery life, fetch less frequently.
Setting Push to OFF (or setting Fetch to Manually on the Fetch New Data screen) overrides individual account settings.

How to keep your forum Userid when changing Oracle SSO accounts?

I have one SSO account which is linked to my forum user TimW. Does anyone know how I can move this forum account to another Oracle SSO account without changing the forum handle or losing any of the post history?
Thanks
Tim

Thanks for the advice. But I already have another SSO account. The old one is linked to my account in this forum and the new one is linked to all sorts of other stuff, like MoS etc! I can't change the name of the old SSO account as the system says the new address already exisits. I guess my only options are a) to delete the new account and then change the old one, or b) stick with both accounts. Unless you have any other suggestions ....
Regards
Tim

How to not retriggered output type when changes are made in Purchase Order

Hi All,
Could you let me know how can I resolve this one?
We have a custom output type. Now this output type should NOT be automatically retriggered if a change is made to the document/purchase order. Currently the system automatically repeating the output type for every change made to the document/purchase order. But there is still an option for the user to be able to manually repeat the output.
TIA

Hi,
1.In order to restrict the output type to trigger you need to write the requirement routine in transaction
VOFM> requirements>output control.
2. create the requirement routine in application EF and write the required logic and pass the sy-subrc EQ 4 if you not require to trigger the output type and pass sy-subrc equal 0 to trigger the output type.
3. assign this requirement routine to custom output type.

How to dynamically discover runtime properties of app server within webapp

Hi friends,
Does anyone know if the Servlet API provide any methods to dynamically discover app server runtime properties such as which http and https ports the server is listening at?
It's not the same as ServletRequest.getServerPort() which only give you back the port the incoming request comes from.
I want to be able to say redirect user requests to https, WITHOUT in advance knowledge of the https port configured for the app server, which means no hardcoding of the port number.
Thanks very much for help.

You could always add a web resource collection to your web.xml and specify the transport guarantee to be integral.
