What privileges are need for a normal Oracle user to access V$ and DBA_ views?

Question

I'm connecting to Oracle 19c as HR user. I want to execute the following SQL and some dba_... views:

select s.sid
      ,s.serial#
      ,s.username
      ,s.machine
      ,s.status
      ,s.lockwait
      ,t.used_ublk
      ,t.used_urec
      ,t.start_time
from v$transaction t
inner join v$session s on t.addr = s.taddr;

Oracle tells me the objects doesn't exist. It seems like a permission issue. What privileges are needed for me to access dynamic performance views and DBA_... views?

Answer 1

If you want to allow that user to read all system views, you can use

grant select_catalog_role to the_user;
