I am using the cloning method to copy the AGENT_HOME from machine1 to machine2.

As part of the process I have to run and it is throwing java heap space error.

$agentca -f

Stopping the agent using /usr/apps/oracle/product/oracle10g/agent10g/bin/emctl stop agent

So I asked the unix admin and he said modify the runConfig.sh to put these options to increase the heap space.

/usr/apps/oracle/product/oracle10g/agent10g/jdk/jre/bin/java -Xms64m -Xmx256m -classpath .................

but the command is still failing....

Any ideas on what I should do next ?

You could try increasing -Xmx even further. Perhaps -Xmx1024m

Also have a look in this OTN thread, if you are trying to clone the chained agent.
