Type S (Terminal Session) Entry

Type S (terminal session) entries, described in the following table, contain 164 bytes and supply information about session partners when a session is initiated or terminated. These records are written at session initiation or termination, rather than at the end of the base interval.

Initialization records contain the initiation time; termination records contain data from the beginning of the interval or the session's initiation, whichever is later.

You can collect type S and T records for the same terminal in the same interval: a type S record is generated at session initiation, then at the end of the current interval, a type T record is generated.

Note: The collection of type S records is optional. Records are recorded unless you specify SESSION=NO in the SMF statement of the INITPRM member. Type S records are never written to the log.

2	138	N	Element index
Note: (1) The 'X02' bit added to the flag at decimal offset 71 indicates that response times are not being collected for this session. This means that the last host response, last network response, worst host response, worst network response, cumulative host response, cumulative network response, number of network responses computed, number of responses on targets, and number of transactions terminated at the host fields should not be used for summarizing or reporting information. These fields may contain data; however, this data should not be used for reporting. (2) For non-ESA releases, this field contains the TSO user ID. For ESA releases, this field can contain the TSO user ID (for TSO sessions) or the CA TPX SM user ID (for virtual non-TSO sessions).
