ALTER GLOBAL
returns control to the application without waiting for the transaction to be fully
committed. Automatic transactions are committed in nowait mode. The status
of a nowait transaction is checked by the runtime when the next transaction for
the file is started or when the process terminates.
The default is OFF.
NOWAIT can also be set for separate transactions and for selected programs.
See
for details.
ATMFNOWARNLONGTX { ON | OFF }
suppresses the warning message that is normally displayed in the EMS log
when an automatic transaction runs longer than 5 minutes. The warning is
repeated every 5 minutes until the transaction is committed.
Users should exercise caution when suppressing the long transaction warning
and do so only if the cause for the delayed commit is well understood.
The default is OFF.
ATMFOPTIMIZEUNL[OCKS] | ATMFOPTMZUNL[OCKS] { ON | OFF }
specifies that UNLOCKFILE operations performed on audited files by an
application process are eliminated. NonStop AutoTMF software considers all
locks on the file released and attempts to commit the transaction, subject to the
usual protocol for committing automatic transactions.
This optimization only applies to files that are enabled for automatic
transactions.
The default is OFF and can be overridden for specific programs by using
ATMFREADTHRULOCKS { ON | OFF }
instructs NonStop AutoTMF software to enable or disable read-thru-lock mode
on audited files that use automatic transactions.
The default is ON.
The value can be overridden for a program file set using the
ATMFSEPARATETX
instructs NonStop AutoTMF software to (or not to) generate a separate parallel
transaction for all files under its control.
ATMFSEPARATETX should be used with great caution as it might have a
measurable negative impact on performance.
The default is OFF.
