System properties through -D option...

Where can I get a good listing of all the standard system property values I can pass through the -D flag? I need it for Mac OS X right now, but am also interested in the one for Linux.

I know that, but I'm not looking for the standard options (which are the same for all platforms), but the non-standard ones (often specific to platforms) which one can specify through the -D option in java. How do I know about ones like -Dj3d.sharedctx=false -DAnnotationEngine.loglevel=error (these ones I know, but I want to know about all other properties I can set)?
Actually I want to tweak the default rendering in Mac, and someone suggested to try out different properties.

Where can I change the System properties permanently

Instead of
System.setProperty("name","new-value");
to change the system properties in run-time.
How can I change it in a config file? Where is it?
Thx.

Hai,
We can't directly set the system properties values using config/properties file. But, if you wish to use <b>Spring </b> framework, there is an option to load system properties through a config file.

Using system properties in config file.

HI,
Does anybody know how we can declare System properties in OC4J.
I am talking about using System.getProperty() in java classes.
I need to use this to capture my context realtive path in log4j properties file.

JavaSiva,
If you are using OC4J stand-alone, there are two ways (I know of) to define "System" properties:
* Use "-D" option of "java" command when launching OC4J
* Use "-p" switch recognized by "oc4j.jar" when launching OC4J
Note that I haven't tried OC4J stand-alone developer's preview 10.1.3.1.0 so I don't know if the above is still correct for that version, but it is for every version prior to that one.
Good Luck,
Avi.

Why can't I see an option for ethernet in System Properties?

My wife has just got a new MacBook Pro from work. The wi-fi is working fine, but the ethernet is not. There isn't even an option for it in System Properties. Any thoughts? Is it just a setting that's wrong or do I need to send it back?

Can I Link BOM Node System Properties to Basic Nodes?

Configurator Developer R12
Currently, we utilize basic nodes in the UI that represent the actual BOM nodes which are not displayed in the UI; however, there is a system property, specifically List Price, that is tied to the BOM node that must be visible in the UI next to the appropriate option.
This is currently being handled as a separate cell element in the UI that is manually tied to a specific option, but this method is very manual as it is outside of a Node List Layout Region.
I would like to be able to "link" this system property somehow to the basic node so that I can simply point to the property from the basic node rather than create a row for each option that is linked to the BOM node for just this property. Is there a standard way of "linking" these two node types? Anyone have any experience with this type of need?
Thanks,
Paul

Paul --
Good to know that your desired end state eliminates the dummy Options and uses Properties (whether maintained in Configurator Developer or imported from Inventory Catalog Group Descriptive Elements) to deal with the display captions. This would definitely be the preferred solution, and only if there is a compelling reason why it is not feasible should the scheme I'm about to outline be considered.
The best way to implement a List Price "linking" mechanism is by leveraging User String Properties. Think of these as dynamic Properties, whose values can be set by a Configurator Extension at runtime. (They're documented in the "User String Properties" section of Chapter 6 of the Oracle Configurator Extensions and Interface Object Developer's Guide.) Your CX would iterate through your Option Class(es), and for each Item it would set a User String Property (UserStr01, for example) on the corresponding Option to the Item's List Price. The UI Content Template used for displaying the Option Feature would then be enhanced to display the UserStr01 value along with the name of each Option.
To be as reusable and as generic as possible, you want your CX to have as little in the way of hardcoded values as possible. As such, you want to handle the mapping of Items to their corresponding Options via your Model Structure, Properties in particular, and not via hardcoded mappings in your CX code. You'll want to define a Property ("Corresponding Guided-Selling Node", for example) on each Option Class that identifies its corresponding Option Feature, and on each Item that identifies its corresponding Option within the Option Feature. In doing so, you eliminate the need to modify your CX whenever changes are made to your BOM. The CX can operate over all the Option Classes on which it finds the Property defined, so if a new Option Class is added it will automatically get picked up, and a new Item added to an existing Option Class will work as long as the Property is defined on it and a corresponding Option is created for it.
Hope this helps, let me know if you have any questions or concerns about it.

Where do I read in the documentation the list of the system properties?

Yep. Sounds stupid. But it's true. I read in all these forums where and how to set the truststore and so on but it would be beautiful to understand it my own.
1. First I read setting the -Djavax.net.ssl.trustStore in the VM arguments.
2. Then I find out the the -D is just for setting something like a static property.
3. Next I want to read about the system properties. Who, what and where the Java tries to get this system property. I do not find it.
What I find is great help in these forums and solving this kind of problems seems easy... I googled and the only place I found info about this is in a boulder.ibm.com site:
http://publib.boulder.ibm.com/infocenter/iseries/v5r4/index.jsp?topic=/rzaha/sysprop2.htm
http://publib.boulder.ibm.com/infocenter/iseries/v5r4/index.jsp?topic=/rzaha/rzahajssesysprops.htm
I also found some info on a sun tutorial but not an official documentation. Do you know where to find it? It seems that my learning is always about finding the right place to find information and not guessing and trying.
Thanks!!

Thanks for your soon reply. Yeah, I found that but I really was expecting a more serious documentation.
I have to admit that it is documented. Yes. But I didn't expect to find that in middle of a guide. But more in a reference or in a specification document. It's inside the "Customization" and in a table, yes... But it's a guide!!
I like Java but something to worry about is the "too many - too less" documentation. Documentation is not clear enough and all the hundreds of options you have can make the programming with Java no good. It would sound like a good thing have a lot of choices and hundreds of places to look info for but I am a bit disappointed with that. It's not clear enough to find the right info.
Anyway, thanks a lot for your help!! I will have to live with that.

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

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

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).

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

And it has to be dynamic, since the properties will vary on evry installation.

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

J2ME system properties

In J2ME wireless toolkit, we can add system properties on the "User Defined" tab under settings. These properties can then be accessed by the Midlet. I am using JDeveloper with JWE. From within JDeveloper, I don't see any such option to set system properties. How can I achieve this?
Thanks for your help.

You can manage midlet attributes from the property page of the midlet suite. This is in step 4 with ".MIDletInfo" settings.

Setting System properties and classpath at boot

Hi all,
I'm pretty new to weblogic and I'd need to set some system properties and classpath definitions for my servers at boot. Can I set them via the Administration console or just adding them to the startWeblogic/startManagedWeblogic using the standard -cp and -D flags ?
I've found in the Console, there's the Server Boot properties. However adding them there didn't work. Correct me if I'm wrong, this option can be used ONLY when starting the servers from the Node Manager ?
Thanks
Frank

Hi Frank,
You are right!!!!
But you can set them with in setDomainEnv file under java_option.
Please set under
Unix
JAVA_OPTION = "${JAVA_OPTION} -DXXXXX"
In Windows
set JAVA_OPTION = %JAVA_OPTION% -DXXXXX
Hope this will help you.

Specifying system properties/security manager for OC4J

I have a couple of related questions regarding OC4J/orion.jar:
1. Generically, how can we specify system properties to orion.jar? Being an executable JAR, simply using -D does not work.
2. Specifically, I need to launch the OC4J app server with a Java security manager (with associated security policies, etc.) Java's way of doing this is via -Djava.security.manager=... but this does not work with executable JARs it seems. I tried specifying these parameters via -D and I got a security exception:
Exception in thread "main" java.security.AccessControlException: access denied (java.util.PropertyP
rmission java.protocol.handler.pkgs write)
at java.security.AccessControlContext.checkPermission(Unknown Source)
at java.security.AccessController.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkPermission(Unknown Source)
at java.lang.System.setProperty(Unknown Source)
at com.evermind.server.ApplicationServer.initProtocolHandlers(ApplicationServer.java:652)
at com.evermind.server.ApplicationServer.launchCommandline(ApplicationServer.java:319)
at com.evermind.server.ApplicationServer.main(ApplicationServer.java:314)
So, how do I install the Java security manager with orion.jar? Is there any other way to specify system properties to this, or is there any other way to install the Java security manager for OC4J?
Any help much appreciated.
..Hrishi

Thanks, that seemed to work. However it seems that spawned another little problem. I was using the -Xbootclasspath/a option while firing up orion.jar because I needed to append something to OC4J's default classpath (that is specified in orion.jar's Manifest). Now, when I start OC4J with the -D options for the security policy, it seems to ignore the -Xbootclasspath argument. I have not yet been able to confirm this fact, but based on the ClassNotFoundError I'm running into, that does seem to be the problem.
So I guess my question is, could specifying the -D options to the executable JAR cause it to ignore any other options you may be passing to it (such as -Xbootclasspath)? Is there any sequence in which these args need to be passed?
Thanks.
..Hrishi
Hi,
You can try this :
- Check if you have a file java2.policy in <OC4J_HOME>\config\policy and check if the permission java.util.PropertyPermission "read,write" is granted to <OC4J_HOME>.
if there is no file, you can create one based on <JAVA_HOME>\lib\security\java.policy and grant the approriate privileges.
- Launch OC4J :
java -Djava.security.manager -Djava.security.policy=<OC4J_HOME>/config/java2.policy -jar orion.jar
OR java -Djava.security.manager -Djava.security.policy=<PATH_TO_FILE_POLICY>/<YOUR_FILE>.policy -jar orion.jar

Adding global system properties

Hello,
I know that there are some system properties that are available by default via the System.getProperty method. I also know that I can programatically add my own properties to that list.
My question is...Is there some way for an admin to add custom properties to that list through the Visual Administrator or Configuration Manager?
The reason I ask is because we want to have some properties that will have the same name on each runtime environment but different values. For example, let's say we have a property named NOTES_CONTENT_SERVER which will contain a different server name on DEV, QA and PROD.
Please ask if this question is not clear.
Thanks in advance for any help.
David.

Start the config tool, then in the tree structure in the left hand pane navigate to: cluster-data > instance_XXXXX > server_IDXXXXX (highlight this node).
In the General tab that will appear in the right hand pane you will see a label titled "Java parameters:" with a corresponding text field where you can enter all your JVM parameters. Add your global parameter like so "-Dmy.global.prop=blah".
Save your settings, and restart the cluster, you can then lookup the property in your code: System.getProperty("my.global.prop");
Of cousre you could have learned how to set JVM properties with the config tool on the SAP help site here:
