=_ESCORT_STATEMENT_DATA
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 does occur if the file is not audited and can cause
problems for programs that are not expecting to encounter such records.
Specifying this define precludes the program from reading unexpected null records.
Although automatic transactions are never aborted by NonStop AutoTMF software,
unilateral aborts could leave such gaps in an entry-sequenced file.
Specifying this define overrides the value of the global parameter
ATMFSKIPNULLRECS.
=_ESCORT_STATEMENT_DATA
You can request a process trace that includes data records with the
=_ESCORT_STATEMENT_DATA DEFINE. The DEFINE is added with the following
TACL command:
This define traces a superset of the information traced by the
=_ESCORT_STATEMENT_TRACE. See the description of that DEFINE below.
=_ESCORT_STATEMENT_KEYS
You can request a process trace that includes record key fields with the
=_ESCORT_STATEMENT_KEYS DEFINE.
The DEFINE is added with the following TACL command:
This define traces a superset of the information traced by the
=_ESCORT_STATEMENT_TRACE. See the description of that DEFINE below.
=_ESCORT_STATEMENT_TRACE
You can request a process trace with the =_ESCORT_STATEMENT_KEYS DEFINE.
Each operating system procedure, such as OPEN, KEYPOSITION, READ and WRITE,
that is intercepted by the NonStop AutoTMF software runtime library is traced. The
trace is detailed and can include key fields and entire records if so configured. In
addition, the trace contains much of the process startup information, such as
•
The startup message
•
ASSIGNs passed to the process
•
DEFINEs active when the process started
