Information about current session pools, which are a collection of sessions that are logged on to the database under the same logonid, may be accessed by entering the DISPLAY POOL command. For more information on DISPLAY POOL, see Teradata® Director Program Reference, B035-2416.

LogonSource

Teradata recommends using alternative columns instead of the LogonSource column, if available. For information about the recommended columns for LogonSource, see "LogonSource Column Fields and Examples."

ClientConfCipherSuite and UnityConfCipherSuite

ASCII String representing the confidentiality cipher suite. Currently, this is the TLS cipher suite, for example: "TLS_AES_256_GCM_SHA384".

ClientConfVersion and UnityConfVersion

ASCII String representing the confidentiality version number. Currently, this is the TLS version number, for example: "TLS 1.2".

Possible Values for ClientConfType

Value Description
C TLS used for encryption. Client validated the Certificate-Authority chain but ignored the Subject-Alternative-Name and the Common-Name.
E TDGSS used for encryption. The application does not have the option to change this during the session.
F TLS was attempted but failed, so this is a fallback to using TDGSS for encryption because ENCRYPTDATA is specified.
H TLS was attempted but failed, so this is a fallback to unencrypted because ENCRYPTDATA is not specified.
O May be encrypted using TDGSS or unencrypted. The application has the option of changing this at any time. This is possible only with CLIv2 apps, because drivers (e.g. ODBC, JDBC) do not toggle encryption on and off within a session.
R TLS used for encryption. Server certificate was ignored; client did not validate the identity of the server.
U Unencrypted. The application does not have the option to change this during the session.
V TLS used for encryption. Client validated the Certificate-Authority chain and the Subject-Alternative-Name or the Common-Name.

Possible Values for ClientConnectionType

Value Description
1 Client is connected using TCP/IP via the gateway.
2 Client is connected from a mainframe via a mainframe-attached host.

Possible Values for CurrentCollation

Value Description
A ASCII
E EBCDIC
H Host
M Multinational
C CharSet_Coll
J JIS_Coll

Possible Values for DirUserNetConfidentiality, UnityNetConfidentiality, EffectiveSessionNetConf

When these columns are set to I or C it indicates the level of protection required.

Value Description
I Indicates the level of protection required for Integrity, which is obtained by lookup in the LDAP directory used for security policy. The levels are: Default (D), Low (L), Medium (M), and High (H).
C Indicates the level of protection required for Confidentiality, which is obtained by lookup in the LDAP directory used for security policy. The levels are: Default (D), Low (L), Medium (M), and High (H).

Possible Values for ExpiredPassword

Value Description
Y Yes, by Session Control procedures
N No, by the Parser when a new password is assigned to the user

Possible Values for LogonRedrive

Value Description
' ' Not participating
MEMORY NON-FALLBACK RESPONSES Memory-based Redrive participation
NULL or blanks Session is not participating in Redrive and database restarts will not be transparent to applications and users.

Possible Values for LoadingOp

Value Description
T Session isolated loading is enabled. This is the default setting for a session.
F Session isolated loading is disabled.

Possible Values for Partition

Value Description
7 Console Utility Partition number
8 Partition in which DBC console procedures will be started by the Host utility
9 File System Partition number
10 Gateway partition number
11 Worker Task Partition number
12 Session Control Partition number
13 Dispatcher Partition number
14 Parser Partition number
15 Startup Partition number
17 Resource Sampling Subsystem (RSS) StartUp Partition number
18 Distributed Database File (DDF) Server Partition number
19 Relay Services Gateway (RSG) Partition number
47 Replication Gateway rsgdbsmain partition number

Possible Values for ProxyLogon

Value Description
T The ProxyLogon column indicates if Unity has logged a user onto a TD2 session using existing credentials, when that user was successfully logged on by another Unity-managed Vantage system using TD2. When this occurs, ProxyLogon is set to T.
F False indicates the TD2 session logged on or attempted to log on with a valid password.

Possible Values for ServerConfType

Value Description
E TDGSS used for encryption, either enforced by policy or asserted by a Client.
O May be encrypted using TDGSS or unencrypted, as asserted by a Client, or because it cannot be determined.
T TLS used for encryption.
U Unencrypted, as asserted by a Client Interface.

Possible Values for ServerUnityConfType

Value Description
E TDGSS used for encryption, either enforced by policy or asserted by Unity.
O May be encrypted using TDGSS or unencrypted. Cannot be determined by the gateway.
T TLS used for encryption.
U Unencrypted, as asserted by Unity.

Possible Values for TTGranularity

Value Description
LOGICALROW Row is timestamped with the time the row is processed by the AMP.
REQUEST Row is timestamped with the time the request is submitted.
TRANSACTION Row is timestamped with the time when the first non-locking reference is made to a temporal table, or when the built-in function TEMPORAL_TIMESTAMP is first accessed during the transaction.

Possible Values for UnicodePassThrough

Value Description
S UNICODE PASS THROUGH session attribute is enabled.
F UNICODE PASS THROUGH session attribute is not enabled.

Possible Values for UnityConfType

Value Description
E TDGSS used for encryption.
F TLS was attempted but the handshake failed, so this is an attempt to fallback to using TDGSS for encryption. This is otherwise equivalent to "E".
T TLS used for encryption.
U Unencrypted.
