Starting of domain and managed server through script

Dear experts,

I have a business requirement that all the domains and their respective managed server should be started through a script.  A script should find that how many managed servers are there in a domain and accordingly start the managed server also.  It should ask for userid/password of domain.  As  we start we start the domain using startWeblogic.sh and nodemanager using startNodemanager.sh.  I have 4 domains name java_domain, forms_domain, base_domain, and riha_domain and each and every domains have 7-8 managed server, so please help me to create a script which should start the domains and their managed server also.
