The Question is:
Does RMS support 'HA', in relationship to Tuxedo?
The Answer is :
Terse questions beget terse answers, and potentially answers to
questions other than those that were intended.
The Wizard will assume you are refering to "High Availability" by
your use of the acronym HA.
There are likely as many meanings of the phrase High Availability
as there are folks involved in the discussion.
There are many High Availability features present in OpenVMS. There
are features of and optional packages for the OpenVMS I/O subsystem
and RMS that can provide availability features -- examples include
volume shadowing, clustering, and RMS journaling.
Please contact BEA for information on Tuxedo.
