Hi all,

Under Oracle, you can set the number of blocks to read (multiblock_read)
as well as the block size you'll use under a database.

If the OS can handle reads of a certain amount, then as a DBA you size
these factors to be equivalent to the maximum amount of data that can be
read at once by the OS from disk.

For example, if an OS can read 32K in one read, and oracle's block size
is set to 8K, then multiblock_read would be set to 4, as in 4 = 32K/8K

My question then is, what is the maximum amount of data a single read
can retrieve under linux? I'm running RH6.2

Also, anyone know what this factor is under Solaris 7?

Thanks,

Ahbaid.
