Hi everyone,

We are planning for a large OLTP database. When issues has been analyzed there is a serious discussion on changing the SUN OS default block size 512k to 2k (or) 4k.

We know INIT parmeter setings for oracle will do for the db_block_size. And it should be in multiples of OS Blocks

But we would like to know whether changing of OS default block size is recommended or not. Kindly experienced people suggest the pros and cons of the same in this issue
