CPU high utilization on OAS Server, how to find the cause of problem ?
437457Jan 14 2009 — edited May 1 2009Hi all,
We are running ADFBC application on OAS 10.1.3.3 on RH Linux ES 4. The database is Oracle 10g on RH Linux also.
here is the setting in opmn.xml :
<data id="java-bin" value="/opt/oracle/OraHome_oc4j/jdk64/jdk1.5.0_17/bin/java"/>
<data id="java-options" value="-server -XX:CompileCommand=exclude,oracle/sql/NUMBER,toBytes
-ms3072M -mx3072M -XX:+AggressiveHeap -XX:MaxPermSize=1024M -XX:AppendRatio=3 -Djava.security.policy=$ORACLE_HOME/j2ee/ittas/config/java2.policy
-Djava.awt.headless=true -Dhttp.webdir.enable=false"/>
Most of time I see (with linux "top" command) that CPU utilizationis 99.9 %
And sometimes at that time user gets very slow that we have to restart the OC4J to the it normal again.
How do I know what is the cause of that problem ?
Thank you very much,
xtanto
