I think in most case, initrans=1 should be enough for most tables, as one block has a transaction slot. unless two different session are DMLing the exact same block, oracle will dynamically allcoate another transaction slot.

If you really want to find out the tables maybe need more initrans, try search v$sql with most executions and sql_text like "insert%' or 'delete%' or 'update%' maybe helps.

If in oracle 9i, try the following SQL:
select * from v$segment_statistics where STATISTIC_NAME='ITL waits' and value>0

> Tables have default INITRANS value.
> I want to set this parameter to a suitable value. Because INITRANS is 1 as default value and I want to avoid from load of dynamic
> But how can I figure out suitable value of this parameter for each table.
