Hi guys And Gram2000,
My instance is fine know and i did recreate the controlfiles successfully. The prolem was that I typed

setenv oracle_sid test
not
setenv ORACLE_SID test

Unix does take serious about case sensitivity.

I could shut down the instance and follow your suggestions to create controlfiles.

THANKS VERY MUCH ALL OF YOU OUT THERE FOR HELPING ME.

THANKS,
