Information Left Over After Termination; Error Messages Displayed During System Loading - Bull DPS 7000 Operator's Manual

3.5.3

Information Left Over After Termination

After system termination, information remains in the system files about the
following:
•
Jobs known to the system,
•
Input enclosures associated with these jobs,
•
Output prepared by (or for) these jobs.
Some information remains in the SYS.LIB system file.
The system dump, if there is one, is stored on the backing store file SYS.BKST.
After an abnormal termination (crash) the system context is partly saved in BKST
and partly kept in main memory. The a reload is automatically forced in order to
process the system dump (refer to Section 3.4.3.5 DUMP). The error context is
rebuilt using BKST and the main memory part that is not damaged by the reload
mechanism.
In the event of a system shutdown, i.e. termination of a session by means of the
TERMINATE_SYSTEM command, all system files are closed. In any other case
they are left open, as are the user files, to be recovered by File Salvager if a warm
restart is requested at the next storage load.
