Hi,

When we are ask to check how many user connections have establish currently,what view should we use to check from the following queries ?

1.select count(*) from v$session where status in ('ACTIVE','INACTIVE')

2.SELECT username,
       extended_timestamp,
       owner,
       obj_name,
       action_name
FROM   dba_audit_trail
WHERE  owner = 'AUDIT_TEST'
ORDER BY timestamp;

Regards,
Database admin

My answer does not change. Which view gives the current connections? Check the documentation.

Michel,

If this is the running query then join v$session and v$sql.

By default in 11.2, if you didn't deactivate it, connections are audited, so query dba_audit_session.

Audit have both past and current connections, if you want only current ones then query v$session (you don't need v$sql to get just the connection information).

First thing you should clarify is EXACTLY what the person asking the question wants to know because with a structure like the one balckswan described they could be asking at any level of the stack.
