You remember correctly. From ask tom (http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:21545894805637):This attempts to make sure that the data is consistent, yes. However, I **think** that if you do the export as "/ as sysdba" then for some reason it may not actually be consistent! Now I'm sure to be corrected in this because I read it about 6 months ago and now I cannot find where I read it. So apologies in advance if I'm misleading you.
Ahh -- they tricked you -- read only transactions are*NOT SUPPORTED* for "sys" (as sysdba or otherwise) and they are using a read only transaction. the documentation has this to say: <quote> CONSISTENT=y is unsupported for exports that are performed when you are connected as user SYS or you are using AS SYSDBA, or both. </quote> Harel Safra
