Access to Hardware Support to Generate Random Numbers
Make sure all client and server IDs have access to /dev/random. This will allow for faster random number generating. To test that a user ID has access to /dev/random, issue the following command from that user ID in USS:
> head /dev/random | od -x
If you see random numbers, this user has access to /dev/random.
If access to /dev/random is needed and not granted, this could lead to possible RACF messages on the operator’s console.
Make sure users have access to the ICSF CSFRNG (Integrated Cryptographic Service Facility random number generate) service:
