Have your ever faced Out of Memory Error in your environment ???

What cud be the quick solution ?

One solution is
Edit the orion-ejb-jar.xml file in the $OC4J_HOME/application-
deployments/$YOUR_PROJECT$-ejb.jar directory. Set the attribute max-
instances='x' in all the EJBs deployed <entity-deployment
name="ForumMessageEJB" location="ForumMessageEJB"
wrapper="ForumMessageHome_EntityHomeWrapper23"
max-instances="10"
table="ForumMessageEJB">
<ejb-ref-mapping name="ejb/forummessage" /> <resource-ref-mapping
name="jdbc/biltmart" /> </entity-deployment>

The above is not possible for Production Environment, where it is
difficult to make changes in all the jar files. Any other
alternative approach / methods to configure deployment variables ?
