what command did you use to create the database?
what is the database called them if its not poolserverj_native?
if you did this correctly
coinserver~: sudo mysqladmin create poolserverj_native -p[password]
you would have created the database poolserverj_native
email me your poolserverj.config
and I will take a look at it for you
btw I compiled cgminer for you if you want to use it for testing
wget
http://cablepair.devcoin.org/cgminerjust make sure you chmod +x cgminer before you try to run it
