Would there be any adverse impact in changing resource class DB2 from ATTR(NOMASK) to ATTR(MASK)?

Answer:

No, there is would be no impact from changing the class to ATTR(MASK).

You just need to make sure to:
1. TSS REVOKE all permissions
2. TSS REMOVE the ownerships
3. Change the class refinition to ATTR(MASK)
4. TSS ADD the ownership back again
5. TSS PERMIT the resources again
