Database and Transaction

Processing Products

The G06.26 RVU contains new features for these database and transaction processing

products:

•

TMF 3.3

•

TS/MP 2.1 (Controlled Availability)

TMF 3.3

The HP NonStop Transaction Management Facility (TMF) includes T2076, T2781,

T8302, T8606, T8607, T8608, T8609, T8652, T8694, T8695, T8696, T8697, and

T8698. For G06.26, TMF 3.3 provides these new features:

•

Ability to add auxiliary audit trails to the TMF configuration while TMF is started,

provided through the TMFCOM ADD AUDITTRAILS command.

•

Controlled Availability: The commit-hold feature is available in the TMFCOM

ALTER AUDITTRAIL command and is controlled through the

COMMITHOLDMODE, RESET COMMITHOLDMODE, and COMMITHOLDTIMER

options. This feature is available only on systems running the HP NonStop Remote

Database Facility (RDF) product that guarantees Zero Lost Transactions

(RDF/ZLT) and is solely provided to those customers on a controlled basis. With

this feature, if the components needed to ensure ZLT on the backup system in an

RDF configuration become unavailable, commit-hold can be activated, and the

Transaction Management Process (TMP) stops writing audit (which includes

transaction commit and abort records) to the primary system. Therefore, when

commit-hold is activated, no transactions are completed on the primary system

without being copied to the backup system, and ZLT is guaranteed. The commit-

hold condition prevails until the problem that activated commit-hold is resolved, a

specified time-out duration expires, or the condition is explicitly suspended or

terminated by a user. Information about commit-hold is also displayed by the INFO

AUDITTRAIL, STATUS AUDITTRAIL, and STATUS TMF commands.

•

but now present in the TMFCOM ALTER TMF command through these options:
