That's strange - with every release I've worked so far, the default value for this parameter was 5. Also, I hope you are aware that this setting has absolutely nothing to do with the actual number of concurent transactions each rollback can handle. This parameter is only relevant at startup to help Oracle decide how many of the available rollback segments to acquire and put online.
