ALTER GLOBAL
ATMFMAXTIME 1-to-n-seconds
specifies that transactions should be committed after n seconds. The value of n
should be a power of 2 (1,2,4,8,16,32,...) in the range of 1 to 4096. If the value
specified is not a power of 2, the value will be rounded to a power of 2.
The default is 16 seconds.
MAXTIME can also be set for separate transactions and for selected programs.
See
for details.
ATMFMAXTX 1-to-1000
specifies the maximum number of concurrent transactions each prepared
program can process.
ATMFMAXTX is rounded up to the next multiple of 100 when NonStop
AutoTMF software opens the TFILE ($TMP).
The default is 100.
If an application program opens the TFILE with a transaction depth greater
than 100, NonStop AutoTMF software also increases its current value of
MAXTX to the value specified by the program, rounded up to the next multiple
of 100.
An application program must open the TFILE before NonStop AutoTMF
software opens the TFILE to have the maximum depth increased under
program control. Once NonStop AutoTMF software has opened the TFILE, it
cannot close and reopen the TFILE with the desired depth.
In such cases, you must configure MAXTX specifically if a value larger than
100 is desired.
To override ATMFMAXTX for a specific program, set the MAXTX option using
.
ATMFMAXUPDATE 1-to-4096
specifies that transactions should be committed after n updates and inserts.
The value of n should be a power of 2 (1,2,4,8,16,32,...) in the range of 1 to
4096. If the value specified is not a power of 2, the value will be rounded to a
power of 2.
The default value is 32 updates and inserts.
MAXUPDATES can also be set for separate transactions and for selected
programs. See
and
for details
ATMFNOWAIT { ON | OFF }
Note. You can set ATMFMAXTX to a value greater than 100 only on NonStop servers
that support a maximum of 1000 transactions (T9055AER and later)
