Want to make use of the nologging option in direct-path-insert.

1)
a. create a table with attribute NOLOGGING
b. insert /*+ append */ .....
this results in a modified unrecoverable_time in v$datafile - as expected

2)
a. alter table test logging
b. insert /*+ append nologging */ ... or ... insert /*+ append */ nologging
Would have expected that unrecoverable_time had changed after issuing this command, but it didn't.
Is No.2 really no NOLOGGING-Operation or is just unrecoverable_time not adjusted as it should.
