Integration

Hi all,
Now I'm using Oracle AS 10.1.3.0, and after some hours, the error "java.lang.OutOfMemoryError: Java heap space" appeared.

And this is the information of OracleAS memory when it has error:

And this is runtime prarameter:
-Xrs -server -XX:MaxPermSize=128m -Xms256m -Djava.security.policy=$ORACLE_HOME/j2ee/home/config/java2.policy -Djava.awt.headless=true -Dhttp.webdir.enable=false

Any one can help me?
