The 1.2.4 upgrade instructions state that a a SELECT Grant on SYS.V_$TABLESPACES is required if not using SYS as SYSDBS. I'm assuming this is a typo. DO you mean v$TABLESPACE or DBA_TABLESPACES?
It will be changed to use DBA_TABLESPACES in the future
The script foex_install.sql reads from V$TABLESPACE
Sorry for the confusion, we'll fix that in the documentation.
Thanks for the response, our DBA is questioning why it needs that access as that dynamic view is mostly concerned with RMAN backup and flashback?
