i am not too sure but i think dirty means that the data that is written to the data files mite also be obsolete. This means that the data has already been deleted from the database yet it is written into the file. This is similar to what people call a dirty read in informix cursors where the data displayed through a cursor does not synchronize with the values in the database instead it loads from the memory.
Hope this helps.

I would appreciate if someone could kindly clear my confusion. What is meant by dirty data buffers? If these are dirty (not good/healthy) why to write to these to data files? TIA!
