ALTER ATMFPROGRAMS
NOTX | NO NOTX
disables or enables (NO NOTX) the generation of automatic transactions for
audited file access.
NOWAIT[TX] | NO NOWAIT[TX] | WAITED[TX]
Enables or disables (NO NOWAIT[TX] or WAITED[TX]) the use of nowait
transactions. If enabled, separate transactions are committed in nowait mode
and 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.
NOWARNLONGTX | NO NOWARNLONGTX
suppresses or restores (NO NOWARNLONGTX) 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 NO NOWARNLONGTX.
OPTIMIZEUNL[OCKS] | NO OPTIMIZEUNL[OCKS]
specifies that UNLOCKFILE operations performed on audited files by the
program fileset are suppressed. 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.
UNLOCKFILE optimization can also be enabled or disabled for a program by
specifying the class map define =_ESCORT_OPTIMIZEUNLOCKS
or
=_ESCORT_OPTMZUNLOCKSOFF.
To enable the optimization for all programs, set the global parameter
ATMFOPTIMIZEUNL[OCKS] to ON.
RECORDTX | NO RECORDTX
generates (or does not generate) an automatic transaction for each locked
record and commits the transaction as soon as the record is unlocked.
RECORDTX is used when a file is accessed by programs in which record
locking sequences do not allow NonStop AutoTMF software to commit
automatic transactions (there is at least one lock held on a record in this file at
any given time).
For this option to take effect, this option must be configured both a program
and a file attribute using ADD ATMFFILESET
or ALTER ATMFFILESET.
