ADD ATMFPROGRAMS

If WAITEDIO is specified for a NOWAIT file open, AutoTMF automatically
performs an AWAITIO operation immediately following the various forms of
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

ADD ATMFPROGRAMS

or

ALTER

ATMFPROGRAMS

.

For further details, see

Changing Nowait IO to Waited IO

on page 4-13.
