Returns the status information of the aborted sessions.
REPLACE FUNCTION SYSLIB.AbortListSessions (HostIdIn SMALLINT, UserNameIn TD_ANYTYPE, SessionNoIn INTEGER, LogoffSessions VARCHAR(1) CHARACTER SET LATIN, UserOverride VARCHAR(1) CHARACTER SET LATIN ) RETURNS TABLE (HostId SMALLINT, SessionNo INTEGER, UserName VARCHAR(128) CHARACTER SET UNICODE, AbortStatus CHAR CHARACTER SET LATIN ) . . . ;
|HostIdIn||Logical ID of a host (or client) with sessions logged on.
A value of -1 indicates all hosts.
|UserNameIn||User name of the session.
An asterisk (*) or NULL indicates all users.
|SessionNoIn||ID of the session to abort.
A value of zero indicates all sessions.
|LogoffSessions||Indicator of whether to log off sessions to Teradata Database in addition to aborting them:
|UserOverride||Indicator of whether to override an ABORT SESSION failure:|
Sessions are marked IN-DOUBT by the 2PC protocol, which governs how transactions are committed by multiple systems that do not share memory. The protocol guarantees that either all systems commit or all roll back.
Usage Notes - AbortListSessions
This table function is only supported in Constant Mode.
AbortListSessions cannot be used to abort delayed utility sessions because these sessions are not completely logged on.
This function provides similar functionality to the PMPC ABORT SESSION request with ListSessions set to ‘N’ or ‘No’.
|HostId||Logical host ID of (or client) the aborted sessions were logged on to. For a PE, HostId identifies one of the hosts or LANs associated with the described PE. For a session, the combination of a host ID and a session number uniquely identifies a user session on the system.
This value is NULL for AMPs. A value of zero represents the Supervisor window.
|SessionNo||Number of the session that was aborted. Together with a given host ID, a session number uniquely identifies a session on the Teradata Database system. This value is assigned by the host (or client) at logon time.|
|UserName||User name of the session that was aborted.|
|AbortStatus||Status of the sessions aborted:
For an ABORT without LOGOFF, any status except NULL indicates the reason the request could not impact the associated session.
For an ABORT with LOGOFF, an I, E, or S status value indicates that the associated session cannot be aborted or logged off.
Example: Using AbortListSessions
SELECT * FROM TABLE (AbortListSessions(1, 'User14', 0, 'Y', 'Y')) AS t1; *** Query completed. 5 rows found. 4 columns returned. *** Total elapsed time was 4 seconds. HostId SessionNo UserName AbortStatus ------ ----------- ----------- ----------- 1 1007 USER14 1 1011 USER14 1 1010 USER14 1 1009 USER14 1 1008 USER14
