HI guys
I have found solution form one of the java threds from sun forums.
"You need to create an environment variable called CATALINA_OPTS. Set the value equal to -Xmx512m
This will work for windows or linux."

How to increase the Heap space of Jdeveloper for about more than 512 MB?

When starting JDeveloper, the application within JDeveloper is throwing the error message:
"could not reserve enough space for object heap"
and a windows popup with the following error message:
"Unable to create an instance of the Java Virtual Machine Located at path: ..\..\jdk\jre\bin\client\jvm.dll "
To resolve these issues, i know that adding the following in ide.conf , jdev.conf will help.
AddVMOption -XX:MaxPermSize=512M
AddVMOption -Xmx512M
AddVMOption -Xms512M
I have got 10 GB of RAM in my desktop machine and virtual memory of 15 GB (page size). I am not able to increse the heap space of Jdeveloper for about more than 512MB. This is really frustrating..I had to restart my jdevloper after 3 or 4 deployments.....Has anyone tried success in increasing the heap space in jdeveloper for about 2 GB?
Regards

Yes, i know that -XX:MaxPermSize has nothing to do with Heap Memory. I Just pasted all my configuration settings to know if some thing or the other has caused the issue.... After hearing few people who increased the heap space to more than 512m , i played with those settings again and figured out few things...Mine is Jdeveloper 11.1.1.4, 64 bit Windows 7 environment, 64 bit Java/ JDK.
First, i was deceived by one suggestion in forum that, keeping max and min heap memory to same size always will yield in good performance...From that time on wards, i was always increasing both and was never able to move more than 512m..But this time, i kept the min memory as constand and kept on changing the max memory ..
Jdev.conf
AddVMOption -XX:MaxPermSize=512M
AddVMOption -Xmx972M (I was never able to increase more than this size, though i have around 10GB RAM, if not Jdev doesnt startup)
AddVMOption -Xms512M
Ide.conf
AddVMOption -Xmx2048M (here i was able to increase)
AddVMOption -Xms512M
But even then, i was not seeing my changed settings at the time of deployment...
starting weblogic with Java version:
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b51)
Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode)
Starting WLS with line:
C:\Oracle\MIDDLE~1\JDK160~1\bin\java -client -Xms512m -Xmx512m -XX:MaxPermSize=512m -Dweblogic.Name=DefaultServer ..........
Then i changed again into
setDomainEnv.cmd of my default domain
set USER_MEM_ARGS=-Xms512m -Xmx2048m -XX:MaxPermSize=512m
Then i stared my deployment...this time i could see a real boost in deployment...and my page was launched in a fraction of minute..
tarting weblogic with Java version:

How to increase the heap space size -is there any parameter to pass to JVM

I created a memory buffering module which can be use to buffer log records and write to hard disk.disk writing is done by a separate thread so the main application won't be delayed. and memory for new errors are allocated dynamically. when i test this it gave this exception Exception in thread "Thread-62" java.lang.OutOfMemoryError: Java heap space then I test 100,000 of log records at a time and sleep the thread for 1 second to let the garbage collector do its job this works fine. but when i increase the log records count further it gave the above error. so i want to know whether is there a way to give the heap memory size to the VM as a parameter before running it.

How to secure the web resources in tomcat server

Hi,
Iam developing a web application using java, frame work struts and tomcat server.
I have to redirect the user, when he used to access site through folder names.

Now, it is showing 404 error page.
Now, i have to redirect it to home page, how can i do it?
Please help me to slove this issue.

404 indicates that the file not found I guess. If you want to redirect to different page, you can use
<jsp:forward> tag

1. Tell more about it, e.g.: OS, a sun jdk or a ibm jdk? 32-bit or 64-bit?
for ibm jdk, look for *.hpd file within the dir.
for sun jdk, add startup option -XX:+HeapDumpOnOutOfMemError
Then analyze them with heap analyzer.
2.MaxPermSize=1024m so big space for class files, really necessary?

Need to find the free space on storage server

Hi,
I need to find the free space on storage server through Java code, and even find whether web server has access to the storage server.
So please tell me how do i do that.

This will be through an API for your "storage
server". It would be helpful if you at least
indicated what this "storage server" is: a NFS? an
FTP site? something else?I forgot to mention that. Its NFS. Please let me know
clearly, what APIs I need to use and in simple how.How am I supposed to clearly know this?
Consult the documentation for your NFS system and figure it out. That's what to do.

Hi
1. Deleting a domain will not hold any references. But make sure that under your user_projects/applications also remove the folder that matches with your domain. Basically under user_projects folder you will see 2 folders named applications and domains. When you create a domain say mySoaDomain, it will crate a folder with the same name under applications folder also with few files like em.ear. If you do this, then you can crate a new soa domain and use the same old name.
2. NOW comes the most important thing. If you create a new SOADomain, at one point, you had to give details for soainfra and mds schemas. If you give your current existing db details (that was used for your old deleted domain), then you may still have the issues. Because the soainfra db may still have the instances for your old process.
3. If you really want to have a full clean soa domain, here is what you do:
a) Run rcu and drop the existing schemas for soainfra and mds.
b) Run rcu again and create above schemas again.
c) Now create SOADomain using config wizard and refer above clean rcu db and you are all set.
3. Under your domain root folder, just searh for files named with your workflow and you should see the .jar location.
