just wonder, how many databases I can create in one environment, will
not open at the same time. just create.

I know if open too many db at the same time, system will slow down, but
how about just create many dbs (just open one at once). will this also
slow down the system?

thanks

assume, only one user access the environment, one database, once.

maybe the cost of opening and closing databases is high. could not
find answer by googling

thanks
