ALTER GLOBAL
The value can be overridden for a program file set using the ADD
ATMFPROGRAMS or ALTER ATMFPROGRAMS and for a file set using the
ADD ATMFFILESET or ALTER ATMFFILESET .
ATMFSEPARATETX
generates a separate parallel transaction for every file managed by AutoTMF.
ATMFSEPARATETX should be used with caution as it might have a
measurable negative impact on performance.
The default is OFF.
ATMFSKIPNULLRECS
ignores zero-length records when reading sequentially through an audited
entry-sequenced file.
If a record is inserted into an audited entry-sequenced file and subsequently
backed out because a transaction is aborted, a zero-length record is left in the
file where the record had been inserted. This cannot occur if the file is not
audited and can cause problems for programs that are not expecting to
encounter such records. Setting ATMFSKIPNULLRECS to ON shelters all
programs from reading unexpected null records in all entry-sequenced files.
Although automatic transactions are never aborted by AutoTMF, unilateral
aborts could leave such gaps in an entry-sequenced file.
The default is OFF.
ATMFSTOPONTMF[ERR]
stops a program that encounters a TMF environmental error.
By default, AutoTMF aborts a program that encounters a TMF error. Setting
this option causes the program to stop without creating an Inspect saveabend
file. A message describing the failure and the returned file system error code is
sent to the EMS log.
See Handling TMF Environmental Errors on page 4-10 for a list of the
applicable TMF errors.
The default is OFF.
ATMFTXHOLDOFF 0-to-n-seconds
keeps automatic transactions active between requests received by a server if
the time between these requests is smaller than n seconds. The value of n
should be between 0 and 120.
The default is 0 seconds and automatic transactions are committed when a
server process replies to a request.
This feature is especially useful for certain types of batch processing that are
implemented as a master process that sends requests to server processes. In
