Usage Guidelines
This section describes typical uses and limitations of NonStop AutoTMF software,
drawn from the experiences of customers.
Preparing Third-party Applications
NonStop AutoTMF and Process Pairs
Auditing Files
Once NonStop AutoTMF software is installed, the programs are prepared, and after
NonStop AutoTMF configuration attributes have been specified, you can enable
auditing of files. Enabling auditing can be performed by using the standard system
utilities FUP and SQLCI, but the NonStop AutoTMF software command interpreter can
also audit entire file sets with a single ALTER command.
The audit attribute may not be changed when a file is open, so you will need to stop
applications that are using the file in order to change the audit attribute.
Non TMF-aware applications
Non TMF-aware applications do not access any audited file. By default:
•
Auditing a file will cause NonStop AutoTMF software to generate automatic
transactions to manage access to the file because there is no active transaction.
•
Access to all audited files occurs under the common transaction.
However you can configure some files to be managed as a separate transaction.
TMF-aware applications
TMF-aware applications access audited files under their own transactions. These
transactions are begun and ended or aborted by the application, not by NonStop
AutoTMF software. The non-audited files that these applications also access can now
be audited and managed by automatic transactions generated by NonStop AutoTMF
software.
NonStop AutoTMF software does not start an automatic transaction if a process
transaction is active. To generate automatic transactions to access newly audited files,
explicitly configure these files by specifying the NonStop AutoTMF software file
attribute COMMONTX or SEPARATETX.
In a mixed NonStop AutoTMF software and application controlled transaction
environment, you must specify to NonStop AutoTMF software which files are managed
