sar -B, pgpgin/s and Oracle Direct I/O

 When running the sar -B command on a Linux 2.6 system I have noticed some large pgpgin/s and pgpgout/s numbers when running an Oracle 10gR2 database with ASM.

The definitions for pgpgin/s and pgpgout/s are: 

              pgpgin/s
		
                     Total number of kilobytes the system paged in  from  disk
		
                     per second.  Note: With old kernels (2.2.x) this value is
		
                     a number of blocks per second (and not kilobytes).
		

              pgpgout/s
		
                     Total number of kilobytes the system paged  out  to  disk
		
                     per second.  Note: With old kernels (2.2.x) this value is
		
                     a number of blocks per second (and not kilobytes

Howdy, Stranger!
