Hi Nirmal,

I was thinking that the script would be manually created, but the certain
parts of the configuration would be extracted, so instead of this:

while [ "$status" = "$START_EXIT_STATUS" ]
do
    $JAVACMD \
    -Xbootclasspath/a:"$CARBON_XBOOTCLASSPATH" \
    -Xms256m -Xmx1024m -XX:MaxPermSize=256m \
    -XX:+HeapDumpOnOutOfMemoryError \
   ...
done

you would have something like this:

while [ "$status" = "$START_EXIT_STATUS" ]
do
    $JAVACMD \
    -Xbootclasspath/a:"$CARBON_XBOOTCLASSPATH" \
    $JAVA_MEM_SETTINGS \
    -XX:+HeapDumpOnOutOfMemoryError \
   ...
done

there would then be a custom properties file that would be read by the
startup script, for example

   JAVA_MEM_SETTINGS= -Xms256m -Xmx1024m -XX:MaxPermSize=256m

You would then have different property files for different products, e.g.

stratos-load-balancer-startup.properties (e.g. for the load balancer
product when installed standalone)

   JAVA_MEM_SETTINGS= -Xms256m -Xmx1024m -XX:MaxPermSize=256m

stratos-manager-startup.properties (e.g. for the manager product when
installed standalone)

   JAVA_MEM_SETTINGS= -Xms256m -Xmx2048m -XX:MaxPermSize=256m

all-in-one-startup.properties (e.g. when all stratos products are installed
in one server)

   JAVA_MEM_SETTINGS= -Xms1024m -Xmx4094m -XX:MaxPermSize=1024m

I don't know if this approach would work, it depends on what startup
configuration varies for each of the products.

Does this help explain?

Many thanks,

Chris
