READ and WRITE. After the AWAITIO completes, AutoTMF commits any
outstanding transactions using the usual algorithms as directed by the
configuration.
AutoTMF saves the values returned by AWAITIO, and returns control to
program as if the READ or WRITE operation were still in progress. For a
READ, the data buffer contains the input data.
WAITTIME sets the maximum number of seconds an operation will wait for
locks to be released. The value specified is from 1 to 4096 and rounded to the
nearest power of 2 (1,2,4,8...). The default is 64 seconds.
For this option to take effect, specify it both as an attribute of a program and as
an attribute of the file using

sets the frequency of the long transaction warning messages displayed in the
EMS log. By default, the warnings are generated every 5 minutes.
The AutoTMF runtime generates periodic EMS messages to alert the
operator of long running transactions, which are usually caused by a
program holding locks and preventing AutoTMF from committing an automatic
transaction.
The EMS message displays the transaction identifier of the long running
transaction, the name of the process holding the locks and the time remaining
before the transaction reaches the AutoCommit limit.
value: is n [ SEC[ONDS] | MIN[UTES] ], between 5 and 510 minutes. A
value entered as n SEConds is rounded up to minutes.
NEVER: suppresses the display of long transaction warning messages.
DEFAULT: resets the interval to 5 minutes.
NO: is equivalent to DEFAULT.
Note. Removing an option specifying NO is different from setting it to the default value. The
default value setting overrides the global (or local) value. Removing the option adopts the
setting from the global (or local) setting.
