to solve this issue all you have to do increasing JVM, to do this follow the below steps :-
- Depend on OS, Open the following File :-
- Windows :- C:\oracle\product\owb11_1\owb\bin\win32\owbclient.bat
- Linux : $ORACLE_HOME/owb11_1\owb\bin\win32\owbclient.bat.
This file will indicate to setownenv.sh or setowbenv.bat usually in the same path. Open it with any editor.
be careful while adding this file If you notice or read this file there is more than one line looking the same, these lines only depend on OS for example in my case i am working on LINUX then i have to add Line that indicate for Linux only.
Next to the line -d64 add new parameter -Xmx=1024M or depend on your work.
Restart OWB now.
