Running Different Versions of NonStop AutoTMF
Software on the Same System
Running Different Versions of NonStop AutoTMF Software on
the Same System
If you need to run different versions of NonStop AutoTMF on the same system, for
example to test a newer version of the product, you must configure an alternate
NonStop AutoTMF software environment (Monitor and MapDB) and install the test
software in a different location than the subvolume currently in use. For details on
configuring and using an alternate environment, see
Configuring and Using an
Alternate NonStop AutoTMF Environment on page A-4 in Appendix A, System
Management .
Disabling NonStop AutoTMF Software
To disable NonStop AutoTMF software and run application programs, use any one of
the following steps:
•
Alter the database files to unaudited. If no files are audited, the NonStop AutoTMF
runtime library will not perform any extra operations to manage automatic
transactions.
•
Stop the NonStop AutoTMF monitor process. If the monitor process is not available
to supply NonStop AutoTMF configuration information, the NonStop AutoTMF
runtime library will revert to the passthrough mode and will not perform any extra
operations to manage automatic transactions.
•
Alter the NonStop AutoTMF global configuration to disable automatic transactions.
The ESCORT CI command is:
ALTER GLOBAL AUTOTMF OFF;
Removing NonStop AutoTMF Software
1. If you have prepared and bound your application’s user libraries with the NonStop
AutoTMF runtime library, restore those user libraries with copies that are
unprepared and unbound.
2. Use the UNPREPARE command to restore the application program object files to
their original state.
3. Stop the NonStop AutoTMF monitor process.
4. Use SQLCI to purge the SysDB and MapDB tables.
5. Use SQLCI to drop any catalog created during installation.
6. Update your startup and shutdown procedures to remove the commands that start
and stop the monitor process.
