ALTER ATMFFILESET
READNULLRECS
(for entry-sequenced files only)
reverses the effect of the SKIPNULLRECS option. See the description of
SKIPNULLRECS below for details.
To instruct the runtime to read null records for all audited entry-sequenced files,
set the global parameter ATMFSKIPNULLRECS to OFF. To request this option
for a specific program, use the
=_ESCORT_READ_NULL_RECS define.
If this option is specified, this specification overrides the value of the global
parameter ATMFSKIPNULLRECS and of the
=_ESCORT_SKIP_NULL_RECS
define.
The default is READNULLRECS.
READTHRULOCK | NO READTHRULOCK
enables or disables read-thru-lock mode on audited files that use automatic
transactions.
If this option is specified, this specification overrides the value of the global
parameter ATMFREADTHRULOCK.
To set this option for a specific program file set use ADD ATMFPROGRAMS or
ALTER ATMFPROGRAMS .
RECORDTX | NO RECORDTX
enables or disables the generation of an automatic transaction for each locked
record and commits the transaction as soon as the record is unlocked.
RECORDTX is used when a file is accessed by programs in which record
locking sequences do not allow AutoTMF to commit automatic transactions
(there is at least one lock held on a record in this file at any given time).
For this option to take effect, the option must be configured both as a program
attribute and as a file attribute using
ADD ATMFPROGRAMS or ALTER
ATMFPROGRAMS .
The RECORDTX file attribute can be specified in addition to other attributes,
such as COMMONTX or SEPARATETX. The other attributes are ignored if
RECORDTX is specified for both the file and the program. If RECORDTX is
specified for a program, but not the file, then the other options, such as
COMMONTX or SEPARATETX, will be in effect.
For further details on the use of RECORDTX, see paragraph Record-Level
Transactions on page 4-12.
SEPARATETX | NO SEPARATETX
enables or disables the use of separate transactions by the programs to
access an audited file. SEPARATETX is used when an automatic transaction is
