Agent Process Throws Error - Could not create the Java virtual machine

We are trying to run a WAN test but the server which hosts required SW is kind of older version
OATS controller version installed is 9.3
Agent version same 9.3 v27628
Java version its showing for 9.3 is - 6.0_24
I got this error message on Agent machine

Can you please tell me if this server is not compatible for running version 9.3.
Or let me know what other problem you see.. I will check the user guide to check compatibility too.
Thanks for looking.

Where do i change the path.. i change it in config file in anget manager folder.
then Agent process started working.. but as we try to test it its still pointing to JRockit thing
can u please tell me where should we set the path.. only in config file or there are env entires too?
Thanks

Installation fails with "Cannot launch the Java Virtual Machine"

I'm trying to install OAS 10.1.3.1. on Windows XPbut after copying all the files the installer starts complaining that it cannot lauch the Java Virtual Machine. Eventually, the process gets to the configuration step where it succeeds with one configuration, then fails with the next, and then finally goes into an eternal loop.
When launching the installer it claims that my environment successfully passes all test for memory size, etc.
Is this a known problem? Is there any way I can get more info about the reason why the JVM could not get lauched? I searched for information in the logs without success. I also tried to play around with the PATH environment variable since I saw some installation note saying that includingthe jre/bin path here could help, but it did not help.
Could anyone, please, give me a hint of how to complete the installation successfully?

Thanks for the hint.

Java Virtual Machine aborted

i am writing a stored procedure in java in DB2.
this stored procedure of mine is calling the service of an External class.
In this external class i have all my return statements in "finally" blocks.
my problem is:
whenever i compile my external class on java 1.2.2 on solaris and run my stored procedure my procedure works fine. but whenever i complie my external class on java 1.3.0 and then run my stored procedure my procedure never terminates.when i see the log file generated by the procedure it shows me the statement "java virtual machine aborted"
when i removed the return statements from the finally blocks and reran the program it worked fine on boh java 1.2.2 and java 1.3.0
can u plz explain why?

can u plz explain why? No.
when i removed the return statements from the finally blocks Do not put return statements in finally blocks. And do not execute code in a finally block that might throw exceptions without wrapping it in a do nothing try/catch block.

I eventually fixed the rest of the samples build process by cleaning up my path.
In run.bat, before the path modification

How does JVM (Java Virtual Machine) relate to XI?

Can somebody describe to me exactly what JVM (Java Virtual Machine) is and how it is related/associated to XI? Responses are appreciated, thanks in advance!

HI,
A Java Virtual Machine (JVM), is a virtual machine that interprets and executes Java bytecode. This code is most often generated by Java language compilers, although the JVM can also be targeted by compilers of other languages. JVMs may be developed by other companies as long as they adhere to the JVM standard published by Sun.
The JVM is a crucial component of the Java Platform. Because JVMs are available for many hardware and software platforms, Java can be both middleware and a platform in its own right - hence the expression "Write once, run anywhere." The use of the same bytecode for all platforms allows Java to be described as "Compile once, run anywhere", as opposed to "Write once, compile anywhere", which describes cross-platform compiled languages.
Starting with J2SE 5.0, changes to the JVM specification have been developed under the Java Community Process as JSR 924[1]. As of 2006, changes to specification to support changes proposed to the class file format (JSR 202[2]) are being done as a maintenance release of JSR 924. The specification for the JVM is published in book form[3], known as "blue book". The preface states:
We intend that this specification should sufficiently document the Java Virtual Machine to make possible compatible clean-room implementations. Sun provides tests which verify the proper operation of implementations of the Java Virtual Machine.
Sun's JVM is called HotSpot. Clean-room Java implementations include Kaffe and IBM's. Sun retains control over the Java trademark, which it uses to certify implementation suites as fully compatible with Sun's specification
we have two caches JAVA,ABAP.
i mean all objects which will execute in JAVA Cache those need the JVM.

Chilla

The model used by a JVM accepts a form of computer intermediate language commonly referred to as Java bytecode. This language conceptually represents the instruction set of a stack-oriented, capability architecture.
Java Virtual Machines operate on Java bytecode, which is normally (but not necessarily) generated from Java source code; a JVM can also be used to implement programming languages other than Java. For example, Ada source code can be compiled to Java bytecode, which may then be executed by a JVM. JVMs can also be released by other companies besides Sun (the developer of Java) -- JVMs using the "Java" trademark may be developed by other companies as long as they adhere to the JVM specification published by Sun (and related contractual obligations).
The JVM is a crucial component of the Java Platform. Because JVMs are available for many hardware and software platforms, Java can be both middleware and a platform in its own right  hence the expression "write once, run anywhere." The use of the same bytecode for all platforms allows Java to be described as "compile once, run anywhere", as opposed to "write once, compile anywhere", which describes cross-platform compiled languages. The JVM also enables such unique features as Automated Exception Handling which provides 'root-cause' debugging information for every software error (exception) independent of the source code.
The JVM is distributed along with a set of standard class libraries which implement the Java API (Application Programming Interface). The virtual machine and API have to be consistent with each other[dubious  discuss] and are therefore bundled together as the Java Runtime Environment.
Execution environment
Programs intended to run on a JVM must be compiled into a standardized portable binary format, which typically comes in the form of .class files. A program may consist of many classes in different files. For easier distribution of large programs, multiple class files may be packaged together in a .jar file (short for Java archive).
The JVM runtime executes .class or .jar files, emulating the JVM instruction set by interpreting it, or using a just-in-time compiler (JIT) such as Sun's HotSpot. JIT compiling, not interpreting, is used in most JVMs today to achieve greater speed. Ahead-of-time compilers that enable the developer to precompile class files into native code for a particular platform also exist.
Like most virtual machines, the Java Virtual Machine has a stack-based architecture.
Although the JVM was primarily aimed at running compiled Java programs, other languages can now run on top of it[1], such as:
* Ruby, with JRuby
* JavaScript, with Rhino
* Python, with Jython
* Common Lisp, with Armed Bear Common Lisp
* Groovy
* Scala
[edit] Bytecode verifier
A basic philosophy of Java is that it is inherently "safe" from the standpoint that no user program can "crash" the host machine or otherwise interfere inappropriately with other operations on the host machine, and that it is possible to protect certain functions and data structures belonging to "trusted" code from access or corruption by "untrusted" code executing within the same JVM. Furthermore, common programmer errors that often lead to data corruption or unpredictable behavior such as accessing off the end of an array or using an uninitialized pointer are not allowed to occur. Several features of Java combine to provide this safety, including the class model, the garbage-collected heap, and the verifier.
The JVM verifies all bytecode before it is executed. This verification consists primarily of three types of checks:
* Branches are always to valid locations
* Data is always initialized and references are always type-safe
* Access to "private" or "package private" data and methods is rigidly controlled.
The first two of these checks take place primarily during the "verification" step which occurs when a class is loaded and made eligible for use. The third is primarily performed dynamically, when data items or methods of a class are first accessed by another class.
The verifier permits only some bytecode sequences in valid programs, e.g. a jump (branch) instruction can only target an instruction within the same function or method. Because of this, the fact that JVM is a stack architecture does not imply a speed penalty for emulation on register-based architectures when using a JIT compiler. In the face of the code-verified JVM architecture, it makes no difference to a JIT compiler whether it gets named imaginary registers or imaginary stack positions that need to be allocated to the target architecture's registers. In fact, code verification makes the JVM different from a classic stack architecture whose efficient emulation with a JIT compiler is more complicated and typically carried out by a slower interpreter.
Code verification also ensures that arbitrary bit patterns cannot get used as an address. Memory protection is achieved without the need for a MMU. Thus, JVM is an efficient way of getting memory protection on simple architectures that lack an MMU. This is analogous to managed code in Microsoft's .NET CLR, and conceptually similar to capability architectures such as the Plessey 250, and IBM System/38.
[edit] Bytecode instructions
Main article: Java bytecode
The JVM has instructions for the following groups of tasks:
* Load and store
* Arithmetic
* Type conversion
* Object creation and manipulation
* Operand stack management (push / pop)
* Control transfer (branching)
* Method invocation and return
* Throwing exceptions
* Monitor-based concurrency
The aim is binary compatibility. Each particular host operating system needs its own implementation of the JVM and runtime. These JVMs interpret the byte code semantically the same way, but the actual implementation may be different. More complicated than just the emulation of bytecode is compatible and efficient implementation of the Java core API which has to be mapped to each host operating system.
[edit] Secure execution of remote code
A virtual machine architecture allows very fine-grained control over the actions that code within the machine is permitted to take. This is designed to allow safe execution of untrusted code from remote sources, a model used by Java applets. Applets run within a VM incorporated into a user's browser, executing code downloaded from a remote HTTP server. The remote code runs in a restricted "sandbox", which is designed to protect the user from misbehaving or malicious code. Publishers can purchase a certificate with which to digitally sign applets as "safe", giving them permission to ask the user to break out of the sandbox and access the local file system and network...
[edit] C to bytecode compilers
From the point of view of a compiler Java bytecode is just another processor with an instruction set for which code can be generated. The JVM was originally designed to execute programs written in the Java language. However, the JVM provides an execution environment in the form of a bytecode instruction set and a runtime system that is general enough that it can be used as the target for compilers of other languages.
Because of its close association with Java the JVM performs the runtime checks mandated by the Java specification. This can make it technically difficult to translate C code (which is much more lax with regard to runtime checking) to the JVM and expect it to run without issuing any warnings.
Compilers targeting many different languages, including Ada and COBOL, have been written.
[edit] Licensing
Starting with J2SE 5.0, changes to the JVM specification have been developed under the Java Community Process as JSR 924[2].

I have updated my iTunes to the newest version, 10-25 on a windows XP system. Now my java virtual machine is not working and I need it to run applet window. My Java is also newest version. What can I do to fix/repair my issue?

I need help with java on windowsXP after updating iTunes to the latest version. My java will not work and I get error message need java virtual machine to run applet window. Did not have this problem prior to the iTunes update.
Please help, Thanks

If your library was working on your computer and then popped up empty all of a sudden then this might be what you need...
Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!

Could not initialize the Java Virtual Machine

While trying to configure the turnkey product I encounter an error in starting the JBoss for Adobe LiveCycle ES v8.0 service. The JBossService.exe ends up showing in the task list - but the service shows its status as "starting" and an enty stating: "Could not initialize the Java Virtual Machine" is placed in the event log. I've seen a posting on this form that traced at least some of these symptoms to the account under which the service is configured to run - but I don't believe that solution applies in this case - I'm starting the service under the System Account which has all the permissions it needs to start the service.

Thanks very much for the suggestion. Indeed, the problem turned out to be memory related - I was able to correct the issue by updating the registry keys "JVM Option Number 4" and "JVM Option Number 5" so specify lower values. For some reason the system didn't like the 1024 meg size that was set by default (our server has 2 gig of memory).

<GC: 1 387875.630047 554 1258496 1 161087488 0 161087488 20119552 0 20119552

There are 2 "full garbage collections", one of reason "1" and one of reason "5".
For the first one "Old generation After " =238778016
For the second "Old generation After " =238778016
Thus, "Old generation Before garbage collection" of the second is higher than "Old generation After garbage collection". Why?
I expected all objects to be allocated in the "Eden" space. And therefore I did not expect to s

I agree but my current Hp support is not very good on JVM issues.

We have 2 full garbage collections, one of Reason 5 and the next oneof Reason
1.
What happened between these 2 garbage collections as we got : "Oldgeneration
After" of row 2 is higher than "Old generation Before" of row 1? Iexpected Objects
to be initially allocated in eden and so we could not get "old generation2modified
between the end of one garbage collection and before the next one.
Could you please clarify this issue and/or give more information aboutgarbage

Saving files and future Java Virtual Machine updates questions

So I've made A program that keeps a list of Ingredients and Recipes for my dads small business. This program is currently on 3 computers my dads, the secretaries, and mine. I made it so it saved and loaded from a shared folder in the network where all the computers has access. The secretary and my dads computer saved and loaded the program fine with changes from one to the other, but mine wouldn't. If I save what information I put on my computer the other computers could no longer load the save file. If i saved something on the secretary or dads computer then my computer would not be able to load the file.
well i solved this problem by re downloading Java virtual machine on my computer.
this brings me to my question:
Will future virtual machine updates make it so the program can't read old .dat files (I've been using ObjectInputStreams and ObjectOutputStreams to save and load)
Sorry for the long story before the question I just wanted to state how I came to the question.

Yes, absolutely. That is one of the problems with using serialization to save data. Fortunately the serialization tutorial mentions it and explains some strategies for minimizing the problem. So have a look at that tutorial.

"Could not create Java virtual machine" for several XP SP3 clients

Hi,
In this last year I got the message "could not create java virtual machine",
(suddenly, after several mounths without any kind of problem),
on 10-15 XP SP3 clients in our lan, lan in which all the 200 clients (90% XP SP3)
have this application installed.
Every time the solution seems to be different:
sometimes the cause is a virus, sometimes i have to disinstall all Java components
and reinstall only the Java RE 6.0_23 (used by the application),
sometimes I have to make also a system registry cleaning for Java components,
only few times was enough to clear the Java cash, change the kind of Java network connection,
delete the temporary files...
In two situations the problem was solved changing UltraVnc with RealVnc
and only once the user solved himself restarting the computer...
I'd like to know which is the meaning of this message and which steps is better
to follow in order to solve the problem in the shortest time.
Thank You

Thank you
for anwering my question !
Anyway, in all the 10-15 cases I solved this problem, I hadn't to change the amount of RAM...
never... and, once solved, the computer client is ok and the application works without subsequent problems...
So, as I said, i can solve the problem without Knowing the real reason, and often after several
hours... (you can read in my previous comment about a lot of differences solutions...)
The matter is... that I can't understand "how and why" I solve the problem...
Bye

Could not create the Java virtual machine What happen?

all,good day!
i use tomcat7 and JRockit JVM;

in R28 jrdoc ,The -XgcPrio option is deprecated in Oracle JRockit R28. The option works in R28, but Oracle recommends that you use -Xgc instead. For more information, see -Xgc;
in -Xgc option info lists the garbage collection modes that i can specify with the -Xgc option. pausetime mode in which the option；

Could not create the Java virtual machine.
what's wrong in my configuration ?
Edited by: 944618 on 2012-7-5 上午4:26

I would add the jvm flag -showversion next to the -Xgc:pausetime flag, so you will see which JVM you're actually running.
Also, the following part of your post is a bit inconsistent, which jvm flag are you actally using?
"but，but，i use -Xgc:pausetime in my tomcat7;tomcat startup error:

The error output you posted looks like the error you would get from a R27 version of JRockit.
