incomplete transaction
I
incomplete transaction. A transaction that was active when the system failed; ultimately,
TMF backs the transaction out of the database.
independent product (IP). A licensed software product, independent of the standard
operating system release version update (RVU) and delivery process, that is generally
delivered on separate media from the NonStop Kernel operating system release
software. Independent products ship when ready with no dependency on the standard
operating system release and delivery process. An IP can be independently applied to
the current product release (CPR) or new feature production release (NFPR)
environments by the customer, depending on the availability of the IP’s requisites.
in-doubt transaction. See unresolved transaction.
integrity. The state of a database in which stored information is consistent.
IP. See independent product (IP).
L
large audit-trail file. See format 2 audit-trail file.
local transaction. A transaction that involves a requester, servers, and files that all reside
on the same system. Contrast with distributed transaction.
logical file name. The external file name that an application uses to identify a file stored on
an SMF virtual disk.
long-running transaction. A transaction that runs beyond the time specified by the
autoabort threshold or spans more than 45% of the audit trail capacity.
M
master audit trail (MAT). The audit trail that contains TMF control information (such as
commit or abort records for each transaction) and information describing the logical
ordering of audit information in all audit trails in the system. The master audit trail can
also store audit information generated by a set of data volumes. There must be
exactly one master audit trail in any TMF configuration.
Measure performance analysis subsystem. A software product used to collect
performance statistics on a wide range of system resources. With the Measure
application, you can gather data from system components, network components, and
applications. Among these elements, the Measure application allows you to obtain and
display performance statistics for TMF.
