You can change coredump with the ulimit command.
The others need to use kctune(1m) to change the values of kernel parms:
maxdsiz(5) & maxdsiz_64bit(5), maxssiz(5) & maxssiz_64bit(5), maxfiles(5), maxfiles_lim(5)
Note: You can't make the sizes unlimited, you can only increase the kernel parms.
Note: Making maxssiz too large will decrease maxdsiz.
Note: The *_64bit forms must be bigger than the 32 bit limit.
