Setting jvm options

what happens if I have a really big app which uses much memory? how can I expand the heap used by the jvm so that I don't get an OutOfMemoryException? for traditional apps there is a command line option, but for web start ?

Initial and max heap sizes go in your Resources section:
<resources>
<j2se version="1.3" initial-heap-size="80m" max-heap-size="160m"/>

Setting JVM options in a capi program with JMSJVMOPTS

Hello,
          We are using Weblogic's capi to access JMS from a C program. We are running on a Sun Solaris 2.9 machine and linking our program with the 1.4.2 Java Vritual Machine. The program runs ok but we would like to turn on the "verbose:gc" option of the JVM that's started by the capi.
          We've tried using the JMSJVMOPTS environment variable specified in the capi documentation to do this but it doesn't apprear to be working. We set JMSJVMOPTS to "-verbose:gc" and run our program but it doesn't seem to have any affect. Is this the proper way to specify additional options to the JVM when using the capi? Are we doing something wrong? Any help or suggestions would be appreciated.
          Thanks,
          Bill Sublett

Yes you can but you will be implementing a type a schedule which you will have to develop within your BPEL process.
I'm assuming that you are populating a open interface table, or a custom table and the concurrent program reads from this location.
A way you could do this is select from the table before you do an insert, if the row count is X or greater then invoke a concurrent program.

Browser's JVM options

How to set JVM options for the JVM used by IE or Netscape?
for example setting the heap size.

If it is the Java Plug-in you are talking about, then it is explained here: http://java.sun.com/j2se/1.4.1/docs/guide/plugin/developer_guide/control_panel.html
(Look at the "Advanced" section.)

JVM options doesn't accept option with spaces

I am trying to pass an option via JVM options that has spaces in it. In Admin console I set it via
server1->JVM Settings->General->Debug Options.
I specified
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1678 -Xnoagent -Djava.compiler=NONE -Dcom.spss.util.xml.catalog=D:\SWDF\config\catalog with spaces
The path - D:\SWDF\config\catalog with spaces
cannot be retrieved in my code via
String catalogRoot = System.getProperty(CATALOG_ROOT_KEY);
I get
D:\SWDF\config\catalog
I tried surrounding it with single and double quotes but none of these work.
When surrounded by double qoutes I get
"D:\SWDF\config\catalog
Is this a known issue? I am using Sun ONE ver 7. The JVM is
java version "1.4.0_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0_02-b02)
Java HotSpot(TM) Client VM (build 1.4.0_02-b02, mixed mode)
Swavek

Please run a simple test. Create a small standalone application that dumps the system properties it sees to the console. If you can get this to work (i.e. spaces in a property), and the same technique fails for AS7, file a defect report with Sun on the issue.

Unable to set JVM file encoding to UTF-8 on Windows

Hi,
I am running Tomcat on 1.5.0_05 JRE. I tried several things to set the jvm file encoding to UTF-8 instead of the default Cp1252, but no luck yet.
The most intuitive approach seems to be to use a JVM option like
"-Dfile.encoding=UTF-8"
but this does not seem to have any effect. I have a WinXP pro m/c. I saw some bug reports which seemed to indicate that changing the JVM file encoding is not an available feature....is that correct? I would really appreciate any help/pointers on this. I will post the solution if I find something in the meantime.
Thanks,
Sriram

I am fail to set it too. I think it is better to separate the file.encoding into two, one for accept local OS, the other for compile .java and .jsp and so on files. So we can change it and the bugs will be decrease!

Creating jvm-option with asadmin

Hi,
I am trying to create the following JVM option using asadmin:
-Dproperties.dir=C:/Projects/Project1/myproperties
so I used the following command:
create-jvm-options "-Dproperties.dir=C:/Projects/Project1/myproperties"
The command doesn't work. It ends up in the server as two properties:
"-Dproperties.dir=C
/Projects/Project1/myproperties"
including the quotes ("). I also tried:
create-jvm-options --"-Dproperties.dir=C:/Projects/Project1/myproperties" but it just gives the error:
--"-Dproperties.dir : Option does not have an exact match
Can anyone help?
thanks
Steve

Jvm option "-d64" does not recognized by app. server

Product: SunOne App Server v.7 Platform Edition
It seems app. server does not respect jvm option -d64. I've set this option manually in server.xml file and also from management console. None worked. When I debug System properties from my web application it is listed as follows:
sun.arch.data.model=32
Anyone encounter this problem before? Should I set this option from another file or script?
Thanks in advance.

I would think using this capability would require that you are running on a Sparc 64 Solaris machine, and that you specified that Sun ONE should use your locally installed jsdk1.4 package for operation.
Additionally, you would have had to install the supplemental 64 bit support for jsdk1.4 per instructions (http://java.sun.com/j2se/1.4.1/install-solaris-64.html#64bitinstall).
Once this is done, the app server should recognize the "-d64" option.

JVM options for remote debugging

I'm run Tomcat 5.0.28 using service wrapper and i need help with set the required JVM options for remote debugging from ECLIPSE 3.0.0.

Where can I find a complete list of available JVM options for WLS?
For example -Dweblogic.security.SSL.protocolVersion is not listed anywhere
That is NOT a JVM options as I just explained in your other thread - see that thread for details.
JVM options
That "-Dxxx" syntax means you are specifying a system property on the Java command-line when launching Java.
That property can now be accessed in the Java app
You can make up and use ANYTHING you want when you write your own apps - those command line entries will just get added to the standard/default System properties as I explain in your other thread.
Consult the WebLogic documentation (or onliine help if WLS has such a thing) for info on the system properties that have been defined for WLS.

Configuring JVM options in DIM

Hello,
I just installed DIM 9.3.1 in my laptop.ON running a workflow, I get error that session failed and the error reads:
[PMJVM_42023] [ERROR] Failed to load the JVM library: <>
How will I configure "Informatica service" with JVM options. where do I get the option to configure the JVM in informatica.
Any help will be appreciated.

Can you tell me exactly how to create these registry entries for the service without doing it manually? Is this set at the installation of Tomcat, or of the Tomcat service? I am using the conf/jk/jk_nt_service.exe with the wrapper.properties file to create the tomcat service.
Thanks, that was the last piece of the puzzle. It
looks like Tomcat the service, needs to have the -Xms
and -Xmx params set at installation of the service
using the jvm_option switch. Your registry hack let
me configure it after the fact.
The service can not read the system variables, which
is why you have to set them at installation.
Just go to the directory where tomcat.exe resides, and
from a dos prompt type "tomcat.exe /?" and you will
see the jvm_options switch.
Thanks to all of you who replied.

JVM OPTIONS=-Xmx768M in OWB

Hi all,
In my owb client 11.1.0.7.0
run_service.bat file contains JVM OPTIONS-Xmx768M.
is it ok to execute the mapping fast or either i want to increase it to 1024M
Regards,

Hi,
-Xmx768M is the default value in OWB11g
If you have enough physical memory (RAM) available then you can increase this value .
Regarding mapping run : are you facing any performance related issue with -Xmx768M ?
If yes then try setting it to a higher value .
You need to restart the control center service for this change to take affect .
Thanks,

How to set print option for a Billing document using T-code VF02

How to Set Polling Options of a DB adapter From EnterpriseManager/AdminCons

HI All,
We all know after Dragging a DB adapeter we can manually set the polling Options in J developer
However,
My query is how to Set Polling Options of a DB adapter From EnterpriseManager/AdminCons so that we dun hav to change our code and redeploy if any change is asked for.
My DB adapter is deployed to EM.(SOA Server).
Polling Options are like:
From the Polling Frequency list, select how frequently to poll for new records or events.
In the Database Rows per XML Document field, specify the number of rows per XML document when sending events to Oracle BPEL PM or Mediator. This is the batch setting between the database adapter and its consumer: Oracle BPEL PM or Mediator.
In the Database Rows per Transaction field, select Unlimited or enter a value to indicate the number of table rows to process during a single transaction.
When polling the database for events, you can order the returned rows by the selected column by using the Order By list. The best practice is to choose <No Ordering>, as message ordering regardless is not guaranteed without extra configuration.

Hi,
Inside your composite (in the EM), you can see there is a category table call 'Services and References'.
Under it, find the name of your JCA Adapter, where you've define the polling from the DB. Click on it and go to the property tab.
There you can find all the parameters you've set and more.
After you finish update it, click on Apply (this will automatically poll the data).
