Summary :
Increasing heap size using environment variable ARCSIGHT_JVM_OPTIONS

The migration tool document mentions the following:
If you have a very large number of resources, the default 6 GB of heap size on the
Manager may not be sufficient to handle the load. To work around this issue, set
ARCSIGHT_JVM_OPTIONS environment variable to the desired heap size before you
run the migration tool. 

Solution

1) login as arcsight

Check values from $ARCSIGHT_HOME/config/server.wrapper.conf
 wrapper.java.initmemory=4096
 wrapper.java.maxmemory=8192

Set the envrionment variable in the shell to these values you before executing the migration utililty

2) issue following command:

export ARCSIGHT_JVM_OPTIONS="-Xms4096m –Xmx8192m"

3) verify that it is set, issue following command:

echo $ARCSIGHT_JVM_OPTIONS

4) should return

-Xms4096m –Xmx8192m
