Checking NonStop™ TM/MP Status
This subsection explains how to check the status of the NonStop™ Transaction
Manager/MP (TM/MP) and the data volumes it protects.
The main component of NonStop™ TM/MP is the Transaction Management Facility
(TMF) subsystem, a standard Compaq tool that maintains the consistency, integrity, and
durability of a distributed database that is being updated by concurrent transactions. You
use the TMFCOM command interface or the TM View graphical user interface to
manage and operate the TMF subsystem, and as a system operator, you might check
TMF status in your routine system monitoring.
To monitor the basic components of the TMF subsystem using TMFCOM, enter:
> TMFCOM
~ STATUS TMF
