What are the consequences of increasing INITTRANS on a table?

In my particular case (using JDBC), I do not want to increase
the INITRANS value since I am NOT doing any DML activity.
I am doing ONLY a SELECT. Hence, I do not want to increase INITTRANS instead (atleast for me, it doesn't make sense to increase this). I want to change the connection mode that JDBC is doing now (from SERIALIZABLE, READ CONSISTENT).

Any suggestions???
