THE GENERAL SERVER
Locking Records
ON indicates that the data base files to be accessed by
ENABLEGS are audited by TMF. A data base file audited by TMF
is flagged for special handling in preparation for recovery
efforts. For use under PATHWAY, all the files accessed by a
given server class must either be audited by TMF or be
non-audited files.
OFF indicates that none of the data base files to be accessed
by ENABLEGS is audited by TMF.
The default for this parameter OFF.
• WHOLEFILES [ ON ]
[ OFF ]
ON indicates that ENABLEGS is to issue an error message if it
cannot access an alternate key file or a partition of a data
file.
OFF indicates that ENABLEGS does not issue an error message if
it cannot access an alternate key file or a partition of a
data file.
The default for this parameter is OFF.
If you use the General Server in a PATHWAY system, you provide
parameters by using the SET SERVER PARAM command. Refer to the
PATHWAY System Management Reference Manual for information
about this command.
To pass parameters to the General Server outside of a PATHWAY
system, you must use the command interpreter PARAM command.
Refer to the GUARDIAN Operating System User's Guide for more
information about this command.
THE GENERAL SERVER AND LOCKING
The General Server does not perform file-level locking. The
General Server locks a record immediately before issuing an
UPDATE or DELETE and verifies that the old record image
presented by the caller matches the locked record from the file
before proceeding with the modification. If the General Server
detects a mismatch, it returns the current value of the record
with an error status.
