       -Xms100m
       -Xmx1024m
       -Xscmx48m
       -Xshareclasses:name=IBMSDP_%u
       -Xquickstart
       -Xgcpolicy:gencon
       -Xmnx64m
       -Djava.util.Arrays.useLegacyMergeSort=true
       -Dcom.ibm.ws.management.event.max_polling_interval=1000

     • If you are using an IBM 64-bit JRE, then add the following text after the -vmargs line:
