sequential access
Accessing a record on the basis of its position within a predefined record
sequence.
server task
Task of the independent DBH in which the UDSSUB module executes; processes
the requests of the DB application programs.
session
Period between starting and normal termination of the DBH (independent/ linked-
in) in which it is possible to work with the databases of the configuration. Normally,
a session consists of a sequence of session sections and session interrupts.
session abort
Occurs when the DBH is terminated abnormally after a successful session start.
A session abort can be caused by: power failure, computer failure, BS2000
problems, DBH problems, %TERM.
session end
Is the result of:
– DAL when using independent DBH,
– TERM in the DML application program when using linked-in DBH,
– DBH error handling.
During a session interrupt, the user can also effect session end by invalidating
the SLF contents. Inconsistent databases can be made consistent again by a
warm start, even without an SLF.
session interrupt
The period between a session abort and the related session restart.
session job variable
Job variable in which UDS/SQL stores information about a session.
Session Log File (SLF)
File which is permanently assigned to a session and which is required by the
DBH in the event of a session restart. It contains information on the current DB
configuration, the number of current file identifiers and the current values of the
DBH load parameters.
