Java WEB AS - Is it possible to prevent a single process using all memory?

Hi all,
We have a SAP PI 7.0 installation and we have encountered issues with Java mappings utilizing all available memory on the Java stack and causing the server to slow and eventually crash. The original issue was caused by a poorly coded map, but as this is a large installation we want to protect ourselves against any other poor coding that may be on the system or introduced later.
Are there any configuration options within the WEB AS whereby we can either limit the amount of memory available to the execution of any one mapping, or that will enable the server to stop processing once a set limit is reached?
Any help will be much appreciated.
Regards,
- Ian

The only thing that comes to my mind is to use several server processes for the Java instance and limit the max heap size. Once that size is reached, the thread will end with OutOfMemory error but since you have several server processes others threads can continue to work.

  • Bootstrap with Java Web Start: is it possible?

    I'm developing a chat for my university and I want to use Java Web Start. For the application client-side, I've write a class, named URLClientBootstrap.java, put it into a jar file, and my jnlp file refers to it.
    This class does a bootstrap of another class of the server codebase, named AutClient.java and it's correctly throw thanks to JWS. But, if I click on a button, I need to make another bootstrap so, from AutClient.java, I need to bootstrap a class named RegClient.java but this doesn't append.
    Why? I can make only one bootstrap? Or maybe JWS doesn't allow me to start another applet?

    Hi,
    Your concern is legitimate.
    Basically to work with SLD you will not face any problem while creating the Business system but your main intention is to use it in configuration and that is in ID which is a client application and that needs Java Webstart to run on your local machine. Definitely you can create the Business system in SLD but to work with that one you need JavaWebstart
    Java Web Start:
    Using Java Web Start technology, standalone Java software applications can be deployed with a single click over the network. Java Web Start ensures the most current version of the application will be deployed, as well as the correct version of the Java Runtime Environment (JRE)

  • Firefox plugin process takes all memory even if adobe flash isn't installed and java is disabled, and within the browser all plugins are disabled. why ? nsa ?

  • Which solution should I adopt? Applet or Java Web Start?

    Hi,
    I am developing a web application which should print cards through a printer in the client side.
    I would like to use a web start aplication to execute JNI calls in client side, but I am considering a possible solution the use of an Applet aplication to execute that.
    My question is "Which solution should I adopt?"
    Thanks a lot in advance.
    Regards.
    Paulo R. A. Sales.
    Software Architect.

    I would go for Java Web Start, since it is:
    a wonderful tool
    easy to use
    gives you full control
    you don't have to start your browser to print them cards
    But wait for better qualified responses as I haven't written an applaet since school.

  • Can I Include an xml-stylesheet Link in a Java Web-Service?

    The ability to easily create a SOAP-based web-service from a Java class using JDev's built in "Java Web Service" wizard is great.
    From an "Ajax enablement" perspective, I see tremendous value in having the ability to specify an XSL url in the call to that web-service, so that the server will insert an <?xml-stylesheet .../> link to the specified URL prior to the SOAP message that it returns. That way, different callers to the web-service could render the same SOAP response differently (via an XSL transformation performed on the client-side via the XSL they've specified).
    Is there already an undocumented way to do this with an Oracle "Java Web Service" that I am not aware of? If not, adding that capability would be trivial for Oracle, and it would add tremendous value to developers using Oracle's "Java Web Service" capability.

    Hi Chris,
    I take it you are using the RESTful API method to GET the data. In that case you shoul be able to perform a http POST from your js code in order to update the controls.
    This could be done as form components are updated, or after a submit button is pressed (I'm sure you are familiar with this part).
    Please see here for more information: http://zone.ni.com/reference/en-XX/help/371361J-01​/lvhowto/build_web_service/
    I hope this helps.

  • Custom classloader fails when using Java Web Start

    Hope you can help me with a problem that is driving me nuts. I have implemented my own classloader to support plugins. This classloader works as follows:
    1. The classloader is configured to access a plugin components jar file downloaded by jws.
    2. The plugin components jar file contains other jar files which contains the actual plugin code to be loaded using my own classloader.
    3. Upon initialization - my classloader extracts all jar files contained in the plugin components jar file into temporary files.
    4. These temporary files are used by my classloader when defining plugin classes.
    The classloader works fine when not using java web start. Then I launch the application using java web start with security policy in .jnlp file set to:
    <security>
    <all-permissions/>
    </security>
    After a while (it was able to load some of the classes) it fails with the following stack-trace:

    Does anyone have source code for implementing a simple class loader that can be used with Java Web Start (preferrably with all jar files to be used by the classloader wrapped into a jar file)

    If you implement your own classloader, and then still run with a SecurityManager installed, then your ClossLoader is responsible for asigning the permissions to the code it loads.
    You need your ClassLoader to extend SecureClassLoader, and implement the method :
    SecureClassLoader.getPermissions(CodeSource cs) to return the PermissionCollection you want.

    From your post it is not clear what kind of Java web service client (JAX-WS, JAX-RPC, Axis) you are using. The problem being faced is also not clear in the post. Some more elaboration may help others in providing inputs.

  • Java web service using pl/sql DB package - JDev 10.1.3.1

    Hi All,
    I wanted to create a java web service, instead of a pl/sql web service, that calls a pl/sql package in my DB.
    Jdev (10.1.3.1) can generate java code for my pl/sql package. But the generated code can't be used with a java web service. I've found that the generated code uses types that can't be serialized for a webservice (ie. java.sql.Timestamp).
    Does anyone know of a work around?
    Thanks!

    http://www.oracle.com/technology/obe/obe1013jdev/10131/wsfromplsqlpackage/devwsfrom%20plsql.htm
    It's pretty well documented within Jdev also.
    Thanks, Rob

  • Why sun leader do not think about  "Why Java Web Start not be used widely"

    {color:#ff0000}Why sun leader do not think about "Why Java Web Start not be used widely"
    {color}
    Java Web Start was instruduced in jdk1.2, it's about ten years ago,But it's still not widely used--WHY?
    it's not because the design, it's becasue the code--the garbage code-- even the last version not work in many user computers,
    just not work suddendly -- noboday know reason--- if you do not believe, please google internet, many people suffered and suffering from web start!
    It's incredible that a famous big company like sun can not resolve an deployment problen in ten years that some very small company can do good work in much more short time !!!
    That' sun-- always say and design good things, then publish trouble and pain to their users. I really do not know what the sun's engineers are doing in so
    many years! -- why they do not know deployment is so important than others -- if deployment work fine, then the wrong thing can be correct easy !
    Sun, please do an famous big company -- give happy to user rather than pain !!! Please give us -- your users an stable and fast java web start to save us.
    {color:#ff6600}(Note: I use java web start to depoly our application, then receive endless complains, not work, slow and so on. now, we has no way just to give it up--design ourself's deployment-- that's also done by many pained people---just google it){color}
    Here is an desing suggestion:
    Client-end should be simple and stable, should let the server-end do complex thing .(now sun do opposite thing, they make Client-end complex, but server simple) ---it's because that Client-end will take widely effect on user's computer. update a few server is much more easy then update a amount of clients!

  • Any java API to get the metadata for a deployed bpel process in soa/bpm11g?

    Hi,
    Just wonder if this is possible, that there is some existing java api to retrieve the metadata (containing activities, isSynchrous, version information etc) for a deployed bpel process? If not, is there any other way to achieve this goal ( or example query database table directly)?
    I can only find this link for soa11g java api. I am able to invoke the bpel process using this API(direct binding) from java client.
    http://download.oracle.com/docs/cd/E14571_01/apirefs.1111/e10659/index.html?overview-tree.html
    Any help will be greatly appreciated.
    Thanks,
    Bin

    What I find so far:
    1. can get some process property values from ComponentInstance class, see its api.
    http://download.oracle.com/docs/cd/E14571_01/apirefs.1111/e10659/oracle/soa/management/facade/ComponentInstance.html
    Please refer http://blogs.oracle.com/soabpm/2009/07/soa_suite_11g_api_tricks_part.html of how to get the component instance (contain the bpel process) from a composite object
    2. in dev_soainfra database schema, the CUBE_INSTANCE table contains most of soa bpel components information. The BPM_CUBE_PROCESS table seems to contain only the process defined in a bpm application. This sounds a little confused, if we want to develop a bpel application, should it be put in soa or bpm application and what is the difference?
    Please feel free to correct any mistakes here.

  • Prevent JNLP from being cached in the Java Web Start cache

    Hi,
    when i launch a JNLP it's always being cached in the Java Web Start cache. Is there a way to prevent it from being cached? Some attribute/property inside it?
    Thanks!

    Set the http headers in the response from the server when the client downloads the jnlp file.
    eg Cache-control no-cache
    Expires (use same date as "date" header)
    Note that over SSL on Internet Explorer 8 this will not work. All other configurations should be ok.

  • JAVA, JAVA WEB dynpro and possibility of JAVA workflow

    Hi all
    Just a take here -- I'm just getting some feelers on the way WF SHOULD be going in future.
    Since starting to use the JAVA WD system and netweaver developer studio it seems that having to encapsulate a lot of NEW Workflows as ABAP objects is going "Backwards". (Note I said NEW not EXISTING applications)
    I understand that some compatability with existing systems needs to be maintained but if your user is doing all his applications from a Portal you really need the WF's to be triggered from the portal via say WEB SERVICES.
    I find I'm actually using the older ERP / ECC 6.0 R/3 systems these days purely as DATA repositories and from a JAVA program can often retrieve the data via standard BAPI's and RFC calls in a JAVA or Portal application.
    Isn't it about time that the workflow system as a whole was made much more JAVA and PORTAL friendly --since this is where more and more people are doing their developments from.
    Since switching more or less full time over to JAVA WEB DYNPRO developments the whole development time is completed MUCH QUICKER and with many many less mistakes.
    ABAP Web dynpro is also OK but it's still a little bit of a nightmare compared with JAVA when you need a lot of WEB SERVICES.
    Some WF's obviously will need to remain ABAP based but newer custom WF's IMO should be WEB DYNPRO and WEB SERVICE based.
    I can't think of too many large organisations who aren't making more and more use of Portals these days -- so C'mon SAP -- provide some proper Web hooks into WF's instead of us having to go through hoops and rings of writing LAST CENTURY's code to get stuff to work through a Portal.

    Hi,
    Have you checked the new BPM tool that SAP is offering? I think that it is definately a big step into to the drection that you are describing. I haven't really checked all its features and the technology that is is based on, so I am not the biggest expert of this matter.
    Check for example this article to get an overview: http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/b06c49b2-ac63-2c10-3d8d-d17b817ba4ca?quicklink=nw-bpm&overridelayout=true
    Of course it will be a long road before this new tool will (if it will ever) replace the old ABAP based workflow engine.
    I wouldn't totally agree with all the points that you presented (ABAP WD being a nighmare, etc.). Actually I think that the direction (at least in some parts) is the opposite. For example SAP seem to have replaced their "old" travel management applications (Java WD) with new ABAP WD applications, so I see that they believe more in ABAP than Java (of course there might be some financial & other reasons behind this also.). In my opinion WDA has so many advantages compared to WDJ, that I would consider carefully the options when choosing the technology (the possible better(?) compatibilitly with web services might be one of the reasons).
