Answer:
OC4J
as a component of Oracle Application Server
When OC4J
is installed as a component of Oracle Application Server, OC4J system properties
must be manually added to the opmn.xml configuration file. Options will be
passed to managed OC4J instances at startup.
Set Java system properties in the <data> element where the id attribute is
"java-options". This <data> element is enclosed within the
<category id="start-parameters"> subelement of the <ias-component
id="OC4J"> element in the XML structure. For example:
<ias-component id="OC4J">
<process-type id="OC4J_Portal"
module-id="OC4J">
<module-data>
<category id="start-parameters
">
<data id="java-options" value=
"-server -Djava.security.policy=/u01
/oracle/iAS/mid101202/j2ee
/OC4J_Portal/config/java2
.policy -Djava.awt.headless=true -Xms256m -Xmx512m"/>
</category>
...
</module-data>
</process-type>
</ias-component>
Standalone OC4J
OC4J
runtime options can be set by passing arguments on the oc4j.jar command line at
OC4J startup. The syntax for oc4j.jar is as follows:
java [props] -jar oc4j.jar [args]
Note that system runtime options are specified before the oc4j.jar while the
OC4J runtime arguments ([args]) are specified after oc4j.jar in the syntax. For
example:
java -Xms256m -Xmx512m -jar oc4j.jar -validateXML -verbosity 10
Above options set an initial heap size of 256MB and a maximum heap size of
512MB.
Good Luck!
