ADD ATMFFILESET
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, it overrides the value of the global parameter
ATMFSKIPNULLRECS and of the
=_ESCORT_SKIP_NULL_RECS define.
READNULLRECS is the default.
READTHRULOCK
enables read-thru-lock mode on audited files that use automatic transactions.
If this READTHRULOCK is specified, the file attribute value overrides the
global parameter ATMFREADTHRULOCK value.
To set this option for a specific program file set use ADD ATMFPROGRAMS or
ALTER ATMFPROGRAMS .
RECORDTX
generates 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 RECORDTX to take effect, it 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 conjunction with 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
configures files to be accessed by the programs using separate automatic
transactions. Specify SEPARATETX when automatic transactions for a file are
always to be used (even if the process has its own transaction) and the
transaction should be managed separately from transactions for other files.
SKIPNULLRECS
(for entry-sequenced files only)
ignores zero-length records when reading sequentially through an audited
entry-sequenced file.
