Random Number Generator for use in Oracle?

Hi All

I have attempted to load up Oracles cryptographic toolkit to use the random number generator that comes with it.

In svrmgrl I exectuted the following.
connect (as sys user)
@dbmsoctk.sql
@prvtoctk.plb
@dbmsrand.sql

When loading the toolkit I have come across errors when loading prvtoctk.plb.

What is a plb file and does anyone have any suggestions as to what I can do to fix the error listed below?

Is there an easier way to use a random number generator with Oracle?

Thanks in advance

Matt
