Requiring Files to Be Audited
Requiring Files to Be Audited
The NonStop AutoTMF software manages access to audited files in a manner
transparent to application programs. If the audited attribute is removed from any of the
audited files it is managing, the application will continue to operate without any problem
because NonStop AutoTMF software does not attempt to generate transactions for un-
audited files.
In some environments, the accidental or deliberate disabling of audit on such files is
considered a critical event.
You can enforce the requirement that a file be audited:
1. First set the global parameter ATMFABENDNOAUDIT to ON.
2. Then, configure the files for which auditing is critical with one of the following
ATMFFILE options: COMMONTX, SEPARATETX, RECORDTX, or NOTX.
When any of the configured files is opened by a program, NonStop AutoTMF software
checks the audit flag. If the file is not audited, the NonStop AutoTMF runtime abends
the program and sends a message to the EMS log, thus preventing any update to
occur.
Handling TMF Environmental Errors
By default, if a program encounters a TMF environmental error, NonStop AutoTMF
software aborts the program because the program cannot continue processing without
compromising data integrity. This has the side effect of producing large numbers of
saveabend files at a time when the system is under stress.
You can configure NonStop AutoTMF software to stop, rather than abort, a program
that encounters TMF errors. This eliminates the proliferation of saveabend files caused
by TMF problems.
If NonStop AutoTMF software aborts or stops a program when a TMF error occurs, it
sends a message to the EMS log describing the failure and displaying the TMF error
that was encountered.
STOPONTMFERR applies to the following TMF errors:
