An 8.0.6 ops database being migrated to 9i RAC database on Solaris 8. The 8.0 database had an block size of 2k. Multiblock read count is 8. This is an OLTP database, all transactions almost always work on a single row. None of the row sizes exceed the block size. Hardly any chained or migrated rows. Now, during this migration, it was recommended to change the block size to 8k. And my concerns are:
1. Would this not increase pinging across the instances? With 9i and interconnect and cache fusion, this should be reduced considerably, so, is it a mute point? 2. This could alter the execution plans of some statements. Would some, maybe a very few of the statements not prefer a full table scan? Any other positive or negative effects of this increase in block size?
