ADD ATMFPROGRAMS
•
All BEGIN and ENDTRANSACTION operations requested by the
application are ignored.
•
All transactions inherited from requesters through messages on
$RECEIVE are ignored.
•
FILEINFO requests for audited files report that files are not audited.
This facility is for testing only. Programs that make use of TMF may depend on
the correct operation of the calls that are eliminated by setting this option.
Enabling this option may cause program failures and data corruption.
TMF operations may be suppressed for a program by specifying the class map
define =_ESCORT_SUPPRESS_AUDIT.
TXTIMEOUT { value | NEVER | OFF }
specifies how long automatic transactions may live, regardless of the TMF
AutoAbort setting. This feature requires TMF version 3.6 or later.
°
value is n [ SEC[ONDS] | MIN[UTES] ]
value can be between 5 and 510 minutes and overrides the TMF
AutoAbort timer.
°
NEVER specifies that the TMF AutoAbort timer is not in effect.
°
OFF specifies that the TMF AutoAbort is in effect.
If TXTIMEOUT is configured on a system that is not running TMF 3.6 or later, a
warning message is issued, the configuration is updated and the transaction
timeout takes effect when TMF 3.6 is installed.
WAITEDIO
converts NOWAIT I/O operations to WAITED I/O operations.
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.
For this option to take effect, specify it both as an attribute of a program and as
an attribute of the file using ADD ATMFFILESET or ALTER ATMFFILESET.
Note. The AutoTMF AutoCommit timer always applies, regardless of the configured
transaction timeout. If the desired transaction time out value exceeds the default
AutoCommit timer value, the user should adjust the AutoCommit timer accordingly.
See AutoCommit attribute description above on page 6-7
for details.
