<Question>
Hi,
I'm DBA and my company asked me to demonstrate VPD and proxy
authentication of Oracle database EE 10.2 .
I need to learn these things and test some examples described in documentation .
May I for these purposes install on my notebook 10.2 EE database
downloaded from OTN under Development license ?
XE doesn't contain these features :)
Is the trial period restricted to 21 days ?
regards
Janus

Yes, any software download from OTN can be used for
testing/evaluation/development purposes indefinitely.
