Have some problem to start the DB2 embedded database in the appliance. May be I have allocated too little RAM to it?? After some investigation, the DB2 embedded database can be started using the below procedures in a 2GB footprint :

su – db2inst1
/opt/db2/home/db2inst1/sqllib/adm/db2start will fail
>db2 update dbm cfg using INSTANCE_MEMORY AUTOMATIC
