The DBC.SessionInfoX view provides information about currently logged on users, including the session source (host connection, logon name, and application), query band, the current partition, collation, role, password status, type of transaction, LDAP status, and audit trail ID (user authcid).
For information about collections of sessions initiated under a session pool, use the DISPLAY POOL command. For details, see Teradata® Director Program Reference, B035-2416.
If you use a multi-tier client architecture, the LogonSource field of this view can provide distinct source identification because it originates from the server tier, including the user ID and application name.
CLIv2 inserts data strings for TCP/IP sessions into the LogonSource field, which truncates strings that exceed 128 bytes.
