Weblogic Server error - OutOfMemoryError: PermGen space

Question

Dear All,
For Oracle BPM 11g (Implement the Process Model) implementation on windows
I am using windows 7 64 Bit OS. I have 
Installed 10g DB
Run the RCU Utility for SOAINFRA, ORABAM, SSPDM and MDS schemas successfully.
Installed Weblogic Server 11gr1(10.3.5)
Installed Oracle Jdeveloper 11g - 11.1.1.6.0
Installed SOA 11g  using \Java\jdk1.6.0_24
From Jdeveloper I installed the extensions for SOA Composite Editor and BPM studio.
Created Domain for SOA server
All installations, utitlities and configurations completed successfully.
After starting the Weblogic Admin. server (server is up and OK)
The Problem starts here
When I login to weblogic Admin console I get the following error
javax.servlet.ServletException: java.lang.OutOfMemoryError: PermGen space on
the command prompt window and even on the browser window.
I am able to trace the problem.  To get the Idea following are some details of
$MW_HOME/user_projects/domains/soa_domain/bin/setDomainEnv.cmd
call "%WL_HOME%\common\bin\commEnv.cmd"
call "%DOMAIN_HOME%\bin\setSOADomainEnv.cmd"
call "%DOMAIN_HOME%\bin\setSOADomainEnv.cmd"
set WLS_HOME=%WL_HOME%\server
set XMS_SUN_64BIT=256
set XMS_SUN_32BIT=256
set XMX_SUN_64BIT=512
set XMX_SUN_32BIT=512
set XMS_JROCKIT_64BIT=256
set XMS_JROCKIT_32BIT=256

if "%JAVA_VENDOR%"=="Sun" (
    set WLS_MEM_ARGS_64BIT=-Xms256m -Xmx512m
    set WLS_MEM_ARGS_32BIT=-Xms256m -Xmx512m
) else (
    set WLS_MEM_ARGS_64BIT=-Xms512m -Xmx512m
    set WLS_MEM_ARGS_32BIT=-Xms512m -Xmx512m
if "%JAVA_VENDOR%"=="Oracle" (
    set CUSTOM_MEM_ARGS_64BIT=-Xms%XMS_JROCKIT_64BIT%m -Xmx%XMX_JROCKIT_64BIT%m
    set CUSTOM_MEM_ARGS_32BIT=-Xms%XMS_JROCKIT_32BIT%m -Xmx%XMX_JROCKIT_32BIT%m
) else (
    set CUSTOM_MEM_ARGS_64BIT=-Xms%XMS_SUN_64BIT%m -Xmx%XMX_SUN_64BIT%m
    set CUSTOM_MEM_ARGS_32BIT=-Xms%XMS_SUN_32BIT%m -Xmx%XMX_SUN_32BIT%m
set MEM_ARGS_64BIT=%CUSTOM_MEM_ARGS_64BIT%
set MEM_ARGS_32BIT=%CUSTOM_MEM_ARGS_32BIT%
if "%JAVA_USE_64BIT%"=="true" (
    set MEM_ARGS=%MEM_ARGS_64BIT%
) else (
    set MEM_ARGS=%MEM_ARGS_32BIT%
set MEM_PERM_SIZE_64BIT=-XX:PermSize=128m
set MEM_PERM_SIZE_32BIT=-XX:PermSize=128m
After taking the backup
I tried  changing the Permsize to 256, 512 and even 1024.
started the Weblogic Admin server and tried to login, but the same error.
Details of setSOADomainEnv.cmd
set JAVA_OPTIONS=%JAVA_OPTIONS%
set DEFAULT_MEM_ARGS=-Xms512m -Xmx1024m
set PORT_MEM_ARGS=-Xms768m -Xmx1536m
if "%JAVA_VENDOR%" == "Oracle" goto OracleJVM
set DEFAULT_MEM_ARGS=%DEFAULT_MEM_ARGS% -XX:PermSize=128m -XX:MaxPermSize=512m
set PORT_MEM_ARGS=%PORT_MEM_ARGS% -XX:PermSize=256m -XX:MaxPermSize=512m
what are the recommended values I need to put for Permsize in setDomainEnv.cmd?
Do I also need to change the values in setSOADomainEnv.cmd ?
Please correct me where I am wrong. How can the OutOfMemoryError: PermGen space
issue be resolved ?
Thanks

Hi Lakshman,
Thanks for the prompt resonse.
1. How many managed servers do you have in your domain ?
I have only one managed server (soa_server1)
2. If yes, How you are starting the Managed server ? Is that by Nodemanager or Startscript ?
Yes. I start the managed server by startscript (using startmanagedweblogic)
3. Can you check the <managed_server1>.out log file what java heap size is mentioned ?
I have not reached the managed server startup (though it starts and gives
the last line as SOA platform is accepting and running the requiests.
My problem is with weblogic server, which after login I get the Permgen out of memory error.
4. Can you show us the start up arguements of your each managed server ?
   AdminConsole-->Environments---.Servers--->YourManagedServer--->Configuration (TAB)--->ServerStart (SubTab)---> Arguments:(TextArea)
I am not able to get the console. Because when I login the weblogic console,
Immediately I get the  error as
javax.servlet.ServletException: java.lang.OutOfMemoryError: PermGen space
Please clear my doubt as which of the files
setDomainEnv.cmd or setSOADomainEnv.cmd, I should change the values and
into which file and which step.
My priority is weblogic console to be working without any errors. So Far Managed server is OK.
Thanks
